RESUMO

This scoping review aimed to identify methodological procedures for acquiring and analyzing ultrasound images related to swallowing in adults and older adults. The inclusion criteria were based on the PCC strategy (participants, concept, and context), as follows: population (adults and older adults), concept (ultrasound assessment), and context (swallowing assessment). The review included observational, experimental, descriptive, and analytical studies and excluded those that were not available in full, animal studies, in vitro studies, letters to the editor, errata, study protocols, and those that used ultrasound for purposes other than swallowing. There were no language and time restrictions. Two independent blinded professionals selected 81 articles that met the inclusion criteria from different databases. The most evaluated parameters included tongue morphology and movements, hyoid bone displacement, swallowing muscle area, and pharyngeal residue detection, such as pharyngeal wall mobility. They used convex and linear transducers (3 MHz to 8 MHz) positioned in the submental, laryngeal, and lateral regions of the neck. The subjects were seated and instructed to eat different food volumes and consistencies. The literature mapping showed that ultrasound is a promising diagnostic tool, helping clinicians understand swallowing disorders, as it provides static and dynamic images in different modes and positions. Also, patients receive real-time biofeedback of changes related to dysphagia.

RESUMO

Xylanases from thermophilic fungi have a wide range of commercial applications in the bioconversion of lignocellulosic materials and biobleaching in the pulp and paper industry. In this study, an endoxylanase from the thermophilic fungus Rasamsonia composticola (XylRc) was produced using waste wheat bran and pretreated sugarcane bagasse (PSB) in solid-state fermentation. The enzyme was purified, biochemically characterized, and used for the saccharification of sugarcane bagasse. XylRc was purified 30.6-fold with a 22% yield. The analysis using sodium dodecyl sulphate-polyacrylamide gel electrophoresis revealed a molecular weight of 53 kDa, with optimal temperature and pH values of 80 °C and 5.5, respectively. Thin-layer chromatography suggests that the enzyme is an endoxylanase and belongs to the glycoside hydrolase 10 family. The enzyme was stimulated by the presence of K+, Ca2+, Mg2+, and Co2+ and remained stable in the presence of the surfactant Triton X-100. XylRc was also stimulated by organic solvents butanol (113%), ethanol (175%), isopropanol (176%), and acetone (185%). The Km and Vmax values for oat spelt and birchwood xylan were 6.7 ± 0.7 mg/mL, 2.3 ± 0.59 mg/mL, 446.7 ± 12.7 µmol/min/mg, and 173.7 ± 6.5 µmol/min/mg, respectively. XylRc was unaffected by different phenolic compounds: ferulic, tannic, cinnamic, benzoic, and coumaric acids at concentrations of 2.5-10 mg/mL. The results of saccharification of PSB showed that supplementation of a commercial enzymatic cocktail (Cellic® CTec2) with XylRc (1:1 w/v) led to an increase in the degree of synergism (DS) in total reducing sugar (1.28) and glucose released (1.05) compared to the control (Cellic® HTec2). In summary, XylRc demonstrated significant potential for applications in lignocellulosic biomass hydrolysis, making it an attractive alternative for producing xylooligosaccharides and xylose, which can serve as precursors for biofuel production.

RESUMO

Although it is well established that platelet-activated receptor (PAF) and protease-activated receptor 2 (PAR2) play a pivotal role in the pathophysiology of lung and airway inflammatory diseases, a role for a PAR2-PAFR cooperation in lung inflammation has not been investigated. Here, we investigated the role of PAR2 in PAF-induced lung inflammation and neutrophil recruitment in lungs of BALB/c mice. Mice were pretreated with the PAR2 antagonist ENMD1068, PAF receptor (PAFR) antagonist WEB2086, or aprotinin prior to intranasal instillation of carbamyl-PAF (C-PAF) or the PAR2 agonist peptide SLIGRL-NH2 (PAR2-AP). Leukocyte infiltration in bronchoalveolar lavage fluid (BALF), C-X-C motif ligand 1 (CXCL)1 and CXCL2 chemokines, myeloperoxidase (MPO), and N-acetyl-glycosaminidase (NAG) levels in BALF, or lung inflammation were evaluated. Intracellular calcium signaling, PAFR/PAR2 physical interaction, and the expression of PAR2 and nuclear factor-kappa B (NF-КB, p65) transcription factor were investigated in RAW 264.7 cells stimulated with C-PAF in the presence or absence of ENMD1068. C-PAF- or PAR2-AP-induced neutrophil recruitment into lungs was inhibited in mice pretreated with ENMD1068 and aprotinin or WEB2086, respectively. PAR2 blockade impaired C-PAF-induced neutrophil rolling and adhesion, lung inflammation, and production of MPO, NAG, CXCL1, and CXCL2 production in lungs of mice. PAFR activation reduced PAR2 expression and physical interaction of PAR2 and PAFR; co-activation is required for PAFR/PAR2 physical interaction. PAR2 blockade impaired C-PAF-induced calcium signal and NF-κB p65 translocation in RAW 264.7 murine macrophages. This study provides the first evidence for a cooperation between PAFR and PAR2 mediating neutrophil recruitment, lung inflammation, and macrophage activation.

Introduction: Health training, especially in Brazil, has incorporated the International Classification of Functioning, Disability and Health (ICF) in order to develop capacities to deal with human life in the biopsychosocial model. Purpose: Describe and analyze the inclusion of the ICF in undergraduate Speech, Language and Hearing Sciences curricula in Brazil. Methods: A descriptive, cross-sectional study, approved by the Research Ethics Committee, conducted between November 2021 and July 2022. A questionnaire comprising 24 open-ended, multiple-choice questions on aspects relating to the presence of the ICF in the curriculum was made available via Google Forms. Brazilian undergraduate courses in Speech, Language and Hearing Sciences were included, and distance learning courses were excluded. Quantitative analysis was carried out using the SPSS program. Results: Of the 78 Speech, Language and Hearing Sciences undergraduate courses contacted, 28.2% answered the questionnaire. Of the respondents, 50% were in the southeast region and 59.1% were linked to public institutions. Of the participating courses, 27.3% included the ICF in their pedagogical project. Among the courses in which the ICF is present, 50% focus on theoretical subjects, 33.3% on theoretical and practical subjects and 16.7% on theoretical, practical, and complementary activities. Conclusion: The ICF is incipient in Brazilian undergraduate courses in Speech, Language and Hearing Sciences, predominantly in theoretical curricular components. There is a need to broaden the debate about the training of speech therapists about the precepts provided by the ICF, since its inclusion in curricular units, both theoretical and practical, can favor the development of competencies, skills and attitudes focused on the biopsychosocial model.

RESUMO

BACKGROUND: Cisgender men were mostly affected during the 2022 mpox multinational outbreak, with few cases reported in women. This study compares the characteristics of individuals diagnosed with mpox infection according to gender in Rio de Janeiro. METHODS: We obtained surveillance data of mpox cases notified to Rio de Janeiro State Health Department (June 12 to December 15, 2022). We compared women (cisgender or transgender) to men (cisgender or transgender) using chi-squared, Fisher's exact, and Mood's median tests. RESULTS: A total of 1306 mpox cases were reported; 1188 (91.0%) men (99.8% cisgender, 0.2% transgender), 108 (8.3%) women (87.0% cisgender, 13.0% transgender), and 10 (0.8%) non-binary persons. Compared to men, women were more frequently older (40+years: 34.3% vs. 25.1%; p < 0.001), reported more frequent non-sexual contact with a potential mpox case (21.4% vs. 9.8%; p = 0.004), fewer sexual partnerships (10.9 vs. 54.8%; p < 0.001), less sexual contact with a potential mpox case (18.5% vs. 43.0%; p < 0.001), fewer genital lesions (31.8% vs. 57.9%; p < 0.001), fewer systemic mpox signs/symptoms (38.0% vs. 50.1%; p = 0.015) and had a lower HIV prevalence (8.3% vs. 46.3%; p < 0.001), with all cases among transgender women. Eight women were hospitalized; no deaths occurred. The highest number of cases among women were notified in epidemiological week 34, when the number of cases among men started to decrease. CONCLUSIONS: Women diagnosed with mpox presented differences in epidemiological, behavioral, and clinical characteristics compared to men. Health services should provide a comprehensive assessment that accounts for gender diversity.

RESUMO

OBJECTIVES: to integrate evidence from studies on auditory perceptual and speech production effects in communication situations with face mask use. METHODS: an integrative literature review, in MEDLINE, Cochrane Library and Embase databases. The guiding question was: what effects on communication (perceptual-auditory and speech production) occur with face mask use? RESULTS: searches in electronic databases resulted in 1,478 studies and filtering resulted in 29 final studies. CONCLUSIONS: mask use has effects on communication, both in perception and speech production, factors that are also related to quality of life, stress and socio-emotional factors. These data can impact on indicators and alerts in favor of adopting strategies to manage mask use, involving speech production and perception when wearing a mask in health services.

RESUMO

Functionalization of calcium phosphates with biomimetic peptides is a promising strategy to increase cellular response for bone tissue repair. In this work, biphasic calcium phosphate pellets were functionalized with the hydroxyapatite-binding peptide pVTK by dropping a suspension of the peptide on the pellet surface. The bioactivity tests were performed in vitro by using McCoy culture medium. Cytotoxicity tests were also performed to assess cell viability. The material was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy with field emission gun (FEG-SEM). The results showed that functionalization with the biomimetic peptide was most effective in inducing precipitation of bone-like apatite on the pellets surface, when compared to the control groups (two positive control groups and one negative control group). Cytotoxicity tests showed that all samples are biocompatible but the pellets with peptide showed the highest values of cell viability.

RESUMO

Mountain ecosystems experience abrupt abiotic changes that represent environmental filters for many organisms, shaping their phenotypic expressions. However, little is known about the morphological and symmetric adjustments of native bees along altitudinal gradients. We evaluated the changes on wing morphology, wing size, and vein fluctuating asymmetry (FA) of Eulaema nigrita Lepeletier (Apidae: Euglossini) associated with climatic variables along an altitudinal gradient in the rupestrian grassland (known also as campo rupestre or rupestrian field) of Serra do Cipó, Brazil. Seven sampling points along the altitudinal gradient were selected and distributed among 800 and 1400 m.a.s.l., and then, 40 individuals of E. nigrita were collected per each altitudinal point to determine the FA levels and the morphological changes using geometric morphometric techniques. We found that the wing size of E. nigrita decreased with increasing altitude. At the highest altitudes, the levels of FA of the wing veins were greater compared to bees from lower altitudes. We detected significant changes in wing morphology along the altitudinal gradient; bees of lower altitudes showed longer and wider wings than bees of higher altitudes, which had narrower and less elongated wings. Our results show a set of morphological adjustments and phenotypic expressions in E. nigrita associated with the variation in environmental conditions along the altitudinal gradient. We highlight the importance of environmental variables as insect-stressor factors, and that FA and geometric morphometric can be excellent tools for monitoring and evaluating environmental stresses.

RESUMO

OBJECTIVE: Breast cancer treatment has evolved significantly over the years, both in terms of local and systemic approaches. Halsted's radical mastectomy gave way to modified mastectomies and to conservative surgeries, along with breast reconstruction and repair. Although the use of new drugs has directly increased the survival of patients submitted to adjuvant or neoadjuvant systemic therapies, the de-escalation of drugs may also be beneficial in numerous cases. Therefore, breast cancer treatment must be increasingly customized and assessed using a multidisciplinary approach. This study aimed to review the concept and therapy of early breast cancer. METHODS: A narrative review of the literature was carried out in the PubMed database in December 2022, where the keywords for the searches were as follows: early breast cancer, surgical treatment of breast cancer, systemic treatment of breast cancer, neoadjuvant chemotherapy in breast cancer, adjuvant treatment of luminal breast cancer, early triple negative tumor, and early positive Her-2 tumor. Articles that were historically important in the treatment of breast cancer and articles that impacted management with scientific relevance were selected for this review. DISCUSSION: As new evidence continues to update existing knowledge, breast cancer treatment is becoming increasingly personalized and must now take into account the different tumor variants and their clinical stages, the age of patients and relevant comorbidities, as well as personal expectations and desires. CONCLUSION: This literature review of current studies shows that the primary therapy for patients with early breast cancer continues to be surgery, although a customized and multidisciplinary approach is now required.

RESUMO

PURPOSE: Early integration of pediatric palliative care (PPC) for children with cancer is critical to improving the quality of life of both the patient and family. Understanding physician perceptions of palliative care and perceived barriers to early integration is necessary to develop PPC in Brazil. METHODS: The Assessing Doctors' Attitudes on Palliative Treatment survey was modified for use in Brazil. The survey was open from January 2022 to June 2022 and distributed to physicians of all specialties from participating institutions who treat children with cancer. Statistical analysis was complemented by qualitative analysis of open-ended responses. RESULTS: A total of 272 respondents participated. Most respondents reported access to PPC experts for consultation (77.2%) and 34.5% indicated previous palliative care training. Physician knowledge of PPC was generally aligned with WHO guidance (median alignment, 93.0%; range, 80.5%-98.2%). However, about half (53.3%) felt comfortable addressing physical needs of patients receiving PPC, 35.3% addressing emotional needs, 25.8% addressing spiritual needs, and 33.5% addressing grief and bereavement needs. Most respondents (65.4%) felt palliative care should be involved from diagnosis, but only 10.3% stated that this occurred in their setting. The most important barriers identified were physician discomfort (89.0%), limited physician knowledge (88.6%), and lack of home-based services (83.8%). CONCLUSION: Despite a strong understanding of the role of palliative care, physicians in Brazil reported low confidence delivering PPC to children with cancer. Additionally, physicians generally believed that PPC should be integrated earlier in the disease trajectory of children with cancer. This work will direct educational and capacity building initiatives to ensure greater access to high-quality PPC for children with cancer in Brazil to address patient and family suffering.

RESUMO

SUMMARY OBJECTIVE: Breast cancer treatment has evolved significantly over the years, both in terms of local and systemic approaches. Halsted's radical mastectomy gave way to modified mastectomies and to conservative surgeries, along with breast reconstruction and repair. Although the use of new drugs has directly increased the survival of patients submitted to adjuvant or neoadjuvant systemic therapies, the de-escalation of drugs may also be beneficial in numerous cases. Therefore, breast cancer treatment must be increasingly customized and assessed using a multidisciplinary approach. This study aimed to review the concept and therapy of early breast cancer. METHODS: A narrative review of the literature was carried out in the PubMed database in December 2022, where the keywords for the searches were as follows: early breast cancer, surgical treatment of breast cancer, systemic treatment of breast cancer, neoadjuvant chemotherapy in breast cancer, adjuvant treatment of luminal breast cancer, early triple negative tumor, and early positive Her-2 tumor. Articles that were historically important in the treatment of breast cancer and articles that impacted management with scientific relevance were selected for this review. DISCUSSION: As new evidence continues to update existing knowledge, breast cancer treatment is becoming increasingly personalized and must now take into account the different tumor variants and their clinical stages, the age of patients and relevant comorbidities, as well as personal expectations and desires. CONCLUSION: This literature review of current studies shows that the primary therapy for patients with early breast cancer continues to be surgery, although a customized and multidisciplinary approach is now required.

RESUMO

ABSTRACT Objective: to analyze the implementation strategies for adult men's health actions in Primary Care. Methods: action-research conducted with 12 adult men and 14 health professionals from a Family Health Unit in the municipality of Salvador, Bahia, Brazil. Multiple data production techniques were employed, namely: systematic observation, semi-structured interviews, field diaries and contextualized photography, across the action-research stages. Thematic Content Analysis and interpretation based on the axes of the National Policy for Comprehensive Men's Health Care were used. Results: three categories emerged from the conceptions of men and health professionals: health care for men, differentiated strategies, and lessons learned. Discussion: the culture of the strong, unyielding provider man who does not get sick and considers illness as a sign of weakness exacerbates toxic masculinity, requiring a transformation through acknowledging that men are not inherently averse to care but, rather, they are socially shaped. Conclusion: recognizing the institutional barriers became important for the discussion regarding access to health services. The action-research challenges and potentialities enabled the elaboration of an action agenda to enhance access and welcoming at the study health unit.

RESUMO

INTRODUCTION: Infrared thermography has the potential to help assess human head and neck muscles, as thermal variation measurements due to muscle imbalance can contribute to the evaluation and therapeutic follow-up of various clinical conditions in the field of health. OBJECTIVE: This study investigated, with a scoping review, the use of infrared thermography in complementary assessments of human head and neck muscles to determine the extent of research on the topic, what methodologies are used in thermal assessment and thermographic analysis, what regions are assessed, and what results are expected in thermography. METHODS: LILACS, MEDLINE, SciELO, and Web of Science were the databases searched to identify articles published on the topic, with no restriction of language or time of publication. Descriptive, analytical, and experimental observational studies on the assessment of the human head and neck muscle surface temperature with infrared thermography were included. Case studies, case series, methodological accuracy, literature review, animal studies, studies that assessed patients with head and neck cancer, and studies that did not assess head and neck muscle temperature with thermography were excluded. The articles were analysed with a protocol developed by the authors, with data on author, year, country, type of study, sample characterisation, muscles assessed, outcomes investigated, thermal assessment methodology, thermographic analysis methodology and thermography measurements. RESULTS: This review identified and analysed 27 articles. The studies assessed thermal distribution in normal individuals and those with pathologies related to hyper- and hypofunctional head and neck muscle conditions for diagnosis or therapeutic follow-up. The masseter, temporal, digastric, anterior cervical region, orbicularis oris, frontalis, buccinator, suprahyoid, trapezius, sternocleidomastoid and levator scapulae muscles were assessed. Quantitative analyses with area selection tool predominated, considering absolute temperatures and temperature differences. The studies investigated temperature and its relationship with myogenic pain, quantitative assessment of muscle parameters and blood flow velocity. The mean temperature ranged from 32.97°C (±2.21) to 34.90°C, and hyper-radiant and/or asymmetric regions were observed in hyperfunctional conditions and normal subjects after muscle activation. CONCLUSION: Thermography is used in complementary assessments of head and neck muscles, identifying hyper-radiant regions and thermal asymmetry related to muscle tension and activation state. Papers are limited to specific clinical conditions and few muscle groups, besides having great methodological variability.

RESUMO

The use of graphene in surface plasmon resonance sensors, covering a metallic (plasmonic) film, has a number of demonstrated advantages, such as protecting the film against corrosion/oxidation and facilitating the introduction of functional groups for selective sensing. Recently, a number of works have claimed that few-layer graphene can also increase the sensitivity of the sensor. However, graphene was treated as an isotropic thin film, with an out-of-plane refractive index that is identical to the in-plane index. Here, we critically examine the role of single and few layers of graphene in the sensitivity enhancement of surface plasmon resonance sensors. Graphene is introduced over the metallic film via three different descriptions: as an atomic-thick two-dimensional sheet, as a thin effective isotropic material (same conductivity in the three coordinate directions), and as an non-isotropic layer (different conductivity in the perpendicular direction to the two-dimensional plane). We find that only the isotropic layer model, which is known to be incorrect for the optical modeling of graphene, provides sizable sensitivity increases, while the other, more accurate, models lead to a negligible contribution to the sensitivity.

RESUMO

PURPOSE: This study aimed to investigate the effect of transcutaneous electrical nerve stimulation (TENS) associated with vocal therapy in women with behavioral dysphonia. METHOD: Seventeen women with behavioral dysphonia were divided into an experimental group (n = 8) and a placebo group (n = 9). All were submitted to six sessions of vocal therapy, according to the Comprehensive Voice Rehabilitation Program. In the experimental group, therapy was associated with TENS (30 minutes) and in the placebo group, the electrodes were placed and the equipment remained off. The vocal handicap, the voice through the acoustic and auditory perception evaluation, the electrical activity, and the superficial temperature of the suprahyoid and infrahyoid muscles were evaluated. Pre and post data were compared by parametric and nonparametric tests. RESULTS: There was a decreased in vocal handicap of the placebo group (P = 0.002) and a decreased in the percentage of electrical activity of the right (P = 0.036) and left (P = 0.017) infrahyoid muscles of the experimental group in vowel emission and sequential speech (P = 0.036). There was an increase in temperature in the right infrahyoid region in vowel emission (P = 0.027) and the temperature difference decreased quantitatively between the supra and infrahyoid regions in the experimental group. CONCLUSION: TENS associated with vocal therapy reduced the electrical activity of the infrahyoid muscles and balance the temperature between the supra- and infrahyoid regions in women with behavioral dysphonia.

RESUMO

OBJECTIVES: The aim of this study was to review systematically the literature and to investigate the effects of electrical stimulation in treating dysphonia. STUDY DESIGN: This is a systematic review. METHODS: The publications indexed on the MEDLINE, LILACS, PubMed, Web of Science, and SciELO databases were searched. Original articles with experimental, clinical trial and randomized studies involving a control group and approaching dysphonia treatment with electrical stimulation in humans, regardless of age, gender, or race were included. Those excluded were theses, editorials, comments and opinions, reflexive articles, case studies, experimental studies with animals, models, projects, reports and technical reports, and review articles, as well as articles approaching other alterations, not related to dysphonia. RESULTS: Eleven articles were found and it evaluated the effects of neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation on dysphonia caused by vocal fold paralysis, spasmodic dysphonia, behavioral dysphonia, and in patients with vocal fold nodules. The methodological analysis of the articles through the PEDro scale resulted in a mean score of 5.18; the studies were classified as either high quality (N = 3) or fair quality (N = 8). The results indicated that electrical stimulation had a therapeutic effect on various aspects of dysphonia. However, due to the high risk of bias and the heterogeneity of the studies, it is not possible to state the effectiveness of electrical stimulation in treating dysphonia. CONCLUSION: Using electrical stimulation as an evidence-based conventional rehabilitation therapy in the treatment of dysphonia cannot yet be done.
