RESUMO

BACKGROUND AND AIMS: The prevalence and mortality of chronic liver disease has risen significantly. In end stage liver disease (ESLD) the survival of patients is approximately 2 years. Despite the poor prognosis and high symptom burden of these patients, integration of palliative care is reduced. We aim to analyze the agreement between palliative care and hepatology physicians of clinical scenarios that could require palliative care intervention. METHODS: A cross-sectional study was conducted. Palliative care and hepatology physicians were surveyed. Using a five-point Likert scale, their perceptions of palliative care in ESLD were rated. Their agreement in clinical scenarios that could require palliative care intervention were evaluated. Analyses were conducted to assess any differences by primary role (hepatology vs. palliative care) and length of practice (<10 years vs. 10 years). RESULTS: A total of 123 responses were obtained: 52% from palliative care and 48% from hepatology. The majority (66.7%) work in the field for up to ten years. There was a great consensus in 4 of the 8 clinical scenarios. In scenarios with less consensus, the area of activity and length of practice influence the reliance of physicians on palliative care. Involvement of palliative care in ESLD was considered "rare" by 30% and 61% consider difficult to predict the prognosis. More than 90% support medical training in both areas of activity. CONCLUSION: The current involvement of palliative care is considered low, but there are clinical conditions that reveal a clear consensus and there's a unanimous view of the relevance of training.

RESUMO

INTRODUCTION AND OBJECTIVES: Prevalence and mortality of chronic liver disease have risen significantly. In end stage liver disease, the survival of patients is approximately two years. Despite the poor prognosis and high symptom burden of these patients, integration of palliative care is limited. We aim to assess associated factors and trends in palliative care use in recent years. MATERIALS AND METHODS: A Multicenter retrospective cohort of patients with end stage liver disease who suffered in-hospital mortality between 2017 and 2019. Information regarding patient demographics, hospital characteristics, comorbidities, etiology, decompensations, and interventions was collected. Two-sided tests and logistic regression analysis were used to identify factors associated with palliative care use. RESULTS: A total of 201 patients were analyzed, with a yearly increase in palliative care consultation: 26.7 % in 2017 to 38.3 % in 2019. Patients in palliative care were older (65.72 ± 11.70 vs. 62.10 ± 11.44; p = 0.003), had a lower Karnofsky functionality scale (χ=18.104; p = 0.000) and had higher rates of hepatic encephalopathy (32.1 % vs. 17.4 %, p = 0.007) and hepatocarcinoma (61.7 % vs. 26.2 %; p = 0.000). No differences were found for Model for End-stage Liver Disease (19.28 ± 6.60 vs. 19,90 ± 5.78; p = 0.507) or Child-Pugh scores (p = 0.739). None of the patients who die in the intensive care unit receive palliative care (0 % vs 31.6 %; p = 0.000). Half of the palliative care consultations occurred 6,5 days before death. CONCLUSIONS: Palliative care use differs based on demographics, disease complications, and severity. Despite its increasing implementation, palliative care intervention occurs late. Future investigations should identify approaches to achieve an earlier and concurrent care model.

RESUMO

Despite progress in bone tissue engineering, reconstruction of large bone defects remains an important clinical challenge. Here, a biomaterial designed to recruit bone cells, endothelial cells, and neuronal fibers within the same matrix is developed, enabling bone tissue regeneration. The bioactive matrix is based on modified elastin-like polypeptides (ELPs) grafted with laminin-derived adhesion peptides IKVAV and YIGSR, and the SNA15 peptide for retention of hydroxyapatite (HA) particles. The composite matrix shows suitable porosity, interconnectivity, biocompatibility for endothelial cells, and the ability to support neurites outgrowth by sensory neurons. Subcutaneous implantation leads to the formation of osteoid tissue, characterized by the presence of bone cells, vascular networks, and neuronal structures, while minimizing inflammation. Using a rat femoral condyle defect model, longitudinal micro-CT analysis is performed, which demonstrates a significant increase in the volume of mineralized tissue when using the ELP-based matrix compared to empty defects and a commercially available control (Collapat). Furthermore, visible blood vessel networks and nerve fibers are observed within the lesions after a period of two weeks. By incorporating multiple key components that support cell growth, mineralization, and tissue integration, this ELP-based composite matrix provides a holistic and versatile solution to enhance bone tissue regeneration.

RESUMO

Abstract Introduction: End of life care of patients with end-stage kidney disease (ESKD) may be particularly challenging and requires the intervention of a specialized palliative care team (PCT). Objective: To characterize the population of ESKD patients referred to a PCT and evaluate the determinants of planned dying at home. Methods: We performed a retrospective observational cohort study of all patients with ESKD referred to our PCT between January 2014 and December 2021 (n = 60) and further characterized those with previously known ESKD regarding place of death (n = 53). Results: The majority of the patients were female and the median age was 84 years. Half of the patients were on conservative treatment, 43% were on chronic hemodialysis, and the remainder underwent hemodialysis on a trial basis and were subsequently suspended. Of those with previously known ESKD, 18% died at home and neither gender, age, cognition, performance status, comorbidities, CKD etiology, or treatment modality were associated with place of death. Anuria was significantly associated with dying at the hospital as was shorter time from dialysis suspension and death. Although not reaching statistical significance, we found a tendency towards a longer duration of palliative care follow-up in those dying at home. Conclusion: Dying at home is possible in a palliative domiciliary program regardless of age, gender, etiology of CKD, major comorbidities, and treatment modality. Anuria and shorter survival from RRT withdrawal may be limiting factors for planned dying at home. A longer follow-up by palliative care may favor dying at home.


Resumo Introdução: Os cuidados de fim de vida em doentescom doença renal terminal (DRT) podem ser desafiantes e necessitar do apoio de uma equipa especializada em cuidados paliativos (ECP). Objetivo: Caracterizar a população de doentes com DRT encaminhada à ECP e avaliar os determinantes para um fim de vida planeado no domicílio. Métodos: Realizámos um estudo de coorte observacional retrospectivo dos doentes com DRT encaminhados à ECP entre janeiro/2014 e dezembro/2021 (n = 60) e caracterizámos aqueles com DRT previamente conhecida relativamente ao local de fim de vida (n = 53). Resultados: A maioria dos pacientes eram mulheres comidade mediana de 84 anos. Metade dos doentes encontrava-se em tratamento conservador, 43% em hemodiálise crónica e os restantes suspenderam diálise iniciada agudamente. Daqueles com DRT previamente conhecida, 18% morreram em casa. Não foi objetivada associação entre género, idade, cognição, status funcional, comorbilidades, etiologia da DRC ou modalidade de tratamento da DRT e o local de óbito. A anúria e a menor sobrevida após suspensão de diálise associaram-se a um fim de vida no hospital e verificámos uma tendência para o fim de vida em casa nos doentes com mais tempo de acompanhamento pela ECP. Conclusão: O fim de vida no domicílio é possível num programa domiciliário de cuidados paliativos, independentemente de idade, sexo, etiologia da DRC, principais comorbilidades e modalidade de tratamento. A anúria e o menor tempo de sobrevida após suspensão da TRS podem ser fatores limitantes. Um acompanhamento mais longo em cuidados paliativos pode favorecer o fim de vida no domicílio.

RESUMO

Pre-implant bone surgery in oral surgery allows to reconstruct maxillary atrophies related to traumatic, infectious or tumoral processes. In this context, the ideal biomaterial remains autogenous bone, but biomaterials (of natural or synthetic origin) allow to limit the morbidity linked to bone harvesting, and to simplify these surgical procedures. In this article, we illustrate how 3D printing technologies can be used as an adjuvant to treat bone defects of complex shape or to create anatomical models used to plan interventions. Finally, some perspectives brought by tissue engineering and bioprinting (creation of complex in vitro models) are presented.


Title: Impression 3D et bioimpression pour la régénération osseuse en chirurgie orale. Abstract: La chirurgie osseuse pré-implantaire en chirurgie orale permet de reconstruire les atrophies des maxillaires en rapport avec des processus traumatiques, infectieux ou tumoraux. Dans ce contexte, le biomatériau idéal reste l'os autogène mais les biomatériaux (d'origine naturelle ou synthétique) permettent de limiter la morbidité liée aux prélèvements osseux et de simplifier ces interventions chirurgicales. Dans cet article, nous illustrons l'apport récent de l'impression 3D dans ce contexte pour traiter des défauts osseux de forme complexe ou pour créer des modèles anatomiques servant à planifier les interventions. Enfin, les perspectives apportées par l'ingénierie tissulaire et la bioimpression (création de modèles in vitro complexes) sont détaillées.

RESUMO

RESUMO Introdução: No processo de ensino, as estratégias de ensino, como as metodologias ativas, desempenham um papel fundamental na promoção da construção do conhecimento dos alunos, especialmente em disciplinas com temáticas e conteúdos científicos de difícil assimilação. Objetivo: Este estudo teve como objetivo avaliar a percepção dos alunos sobre as metodologias ativas usadas na disciplina de Genética Humana nos cursos de saúde de uma universidade pública do Amazonas. Método: Neste estudo, alunos de Enfermagem, Medicina e Odontologia responderam a um questionário com alternativas de respostas em escalas Likert sobre seis metodologias ativas na sala de aula: construção de modelo didático, gamificação, aprendizagem baseada em equipe, sala de aula invertida, estudo de casos clínicos e aprendizagem baseada em vídeo. Avaliou-se a confiabilidade das respostas, e testes qui-quadrado, Mann-Whitney e Kruskal-Wallis foram usados para análises de associação com nível de confiança de 95%. Resultado: Os participantes, em sua maioria mulheres, tinham uma média de idade de 20,4 ± 3,5 anos. Os alunos de Medicina foram os mais representativos em quatro das seis metodologias ativas usadas. Observou-se uma associação significativa entre o sexo feminino e a preferência pela metodologia de construção de modelo didático, enquanto o sexo masculino tendeu a avaliar mais positivamente a aprendizagem baseada em vídeo. Além disso, a análise individual revelou que a aprendizagem baseada em vídeo foi mais associada ao curso de Odontologia em comparação com Enfermagem, enquanto o estudo de casos clínicos foi mais favorecido pelos alunos de Medicina em comparação com Enfermagem. Isso sugere uma preferência dos estudantes de Odontologia e Medicina por essas metodologias, respectivamente. Quanto ao entendimento do conceito de metodologias ativas, a palavra "aluno" foi a mais frequentemente mencionada. Conclusão: Os alunos reconhecem o envolvimento direto das metodologias ativas, mas têm compreensão parcial dos benefícios. Metodologias ativas em genética humana motivaram e despertaram interesse. Docentes devem considerar a diversidade de competências e preferências dos alunos ao usarem tais metodologias, bem como compartilhar suas experiências e buscar uma educação permanente.


ABSTRACT Introduction: In the education process, learning strategies such as active methodologies play a fundamental role in promoting the construction of students' knowledge, especially in subjects with challenging scientific themes and content. Objective: To evaluate how students perceive active methodologies used in the discipline of human genetics in health courses at a public university in the state of Amazonas. Method: In this study, nursing, medicine, and dentistry students responded to a questionnaire with Likert scale response options relating to six active methodologies in the classroom: construction of didactic models, gamification, team-based learning, flipped classroom, clinical case studies, and video-based learning. The reliability of the responses was assessed, and Chi-square, Mann-Whitney, and Kruskal-Wallis tests were used for association analyses with a confidence level of 95%. Results: The participants, mostly women, had an average age of 20.4±3.5 years. Medicine students were the most representative in four of the six active methodologies used. A significant association was observed between female gender and preference for the didactic model construction methodology, while the male gender tended to evaluate video-based learning more positively. Additionally, individual analysis revealed that video-based learning was more associated with the dentistry course compared to nursing, while clinical case studies were more favoured by medicine students compared to nursing. This suggests a preference of dentistry and medicine students for these methodologies, respectively. As for understanding the concept of active methodologies, the word "student" was the most frequently mentioned. Conclusion: Students acknowledge the direct involvement of active methodologies but have a partial understanding of the benefits. Active methodologies in human genetics have motivated and sparked interest. Educators should consider the diversity of students' skills and preferences when using such methodologies, as well as share their experiences and pursue ongoing education.

RESUMO

Cell polarity is a macroscopic phenomenon established by a collection of spatially concentrated molecules and structures that culminate in the emergence of specialized domains at the subcellular level. It is associated with developing asymmetric morphological structures that underlie key biological functions such as cell division, growth, and migration. In addition, the disruption of cell polarity has been linked to tissue-related disorders such as cancer and gastric dysplasia. Current methods to evaluate the spatiotemporal dynamics of fluorescent reporters in individual polarized cells often involve manual steps to trace a midline along the cells' major axis, which is time consuming and prone to strong biases. Furthermore, although ratiometric analysis can correct the uneven distribution of reporter molecules using two fluorescence channels, background subtraction techniques are frequently arbitrary and lack statistical support. This manuscript introduces a novel computational pipeline to automate and quantify the spatiotemporal behavior of single cells using a model of cell polarity: pollen tube/root hair growth and cytosolic ion dynamics. A three-step algorithm was developed to process ratiometric images and extract a quantitative representation of intracellular dynamics and growth. The first step segments the cell from the background, producing a binary mask through a thresholding technique in the pixel intensity space. The second step traces a path through the midline of the cell through a skeletonization operation. Finally, the third step provides the processed data as a ratiometric timelapse and yields a ratiometric kymograph (i.e., a 1D spatial profile through time). Data from ratiometric images acquired with genetically encoded fluorescent reporters from growing pollen tubes were used to benchmark the method. This pipeline allows for faster, less biased, and more accurate representation of the spatiotemporal dynamics along the midline of polarized cells, thus advancing the quantitative toolkit available to investigate cell polarity. The AMEBaS Python source code is available at: https://github.com/badain/amebas.git.

RESUMO

This study aimed to microencapsulate Cymbopogon citratus essential oil (CCEO) with spray drying using maltodextrin and gelatin. The effects of the operational conditions (inlet temperature (130-160 °C), CCEO concentration (5-15%), maltodextrin concentration (10-20%)) on the physicochemical stability and antioxidant and antibacterial activities of the CCEO microcapsules were determined. The CCEO microencapsulation process had yield and encapsulation efficiency values varying from 31.02 to 77.53% and 15.86-61.95%, respectively. CCEO microcapsules had antibacterial effects against Staphylococcus aureus and Escherichia coli with minimum inhibitory concentration varying from 10 to 20%, and total phenolic contents and antioxidant activities varying from 1632 to 4171.08 µg TE/g and 28.55-45.12 µg/g, respectively. CCEO microcapsules had average diameters varying from 5.10 to 10.11 µm, with spherical external structures without cracks and apparent pores. The best desirable process conditions for CCEO microencapsulation were process inlet temperature of 148 °C, maltodextrin concentration of 15%, and CCEO concentration of 10%. The results showed that CCEO microcapsules with increased stability and low degradation of active components can be prepared by spray drying using maltodextrin and gelatin with the production of microcapsules, which could be exploited as potential food preservatives.

RESUMO

A straightforward and versatile methodology for the extraction of volatile metabolites in biological samples from ruminants for gas chromatography analysis is proposed. The methodology was applied in the determination of multiclass metabolites (short-chain fatty acids, aldehydes, alcohols, ketones, esters, phenols, and sulfides) in different analytical matrices (rumen fluid, urine, and feces) collected from Holstein cows. The 24 multiclass volatile metabolites reported in the different biological samples and their respective concentrations were critically discussed in the context of digestive physiology. Most detected compounds are derived from the rumen and lower gut fermentation of carbohydrates, proteins, and lipids or their metabolism, being consistent with the prior state of the art. The proposed method also takes advantage of the already existing tools in animal nutrition laboratories, providing a novel methodological ground that can generate relevant bioanalytical information with a significant impact on ruminant's nutritional studies.

RESUMO

ABSTRACT Introduction In Brazil, 8,000 new cases of childhood cancer are estimated each year, whose causes are still little known, although some have genetically determined factors. Approximately 70% of human cancers have alterations in the TP53 gene, which encodes the protein responsible for inhibiting the disordered growth of cells exposed to injuries. However, the frequency of alterations in the expression of TP53 in childhood cancers in Brazil remains poorly known. Objective To evaluate the expression of TP53 gene in patients with childhood cancer in northeastern of Santa Catarina, Brazil. Materials and Methods: Retrospectively, 282 patients diagnosed with cancer between 2005 and 2015 in Joinville were included. TP53 expression was evaluated by immunohistochemistry using a score based on the intensity and percentage of stained cells. Results The p53 protein was positive in 25.2% of cases, with no difference between sexes. Considering the five main groups of tumors in the sample, the expression was positive in 31.8%, 27.3%, 20%, 17.2% and 5.9% of lymphomas, nephroblastomas, neuroblastomas, tumors of the Central Nervous System and leukemias, respectively. Conclusion The prevalence of TP53 expression was evaluated in different childhood cancers in the northeastern of Santa Catarina. Positivity was higher among lymphomas and lower in leukemias, but with no significant difference among the five most frequent tumors. Further studies that allow correlation with aggressiveness and disease evolution are required.

RESUMO

Introdução: A doença pulmonar obstrutiva crônica (DPOC) possui alta prevalência e gera altos custos aos sistemas de saúde. A reabilitação pulmonar (RP) é uma intervenção não-farmacológica que gera benefícios clínicos para os pacientes e economia de gastos para o sistema de saúde devido a redução do número de exacerbações da doença e internações hospitalares. Embora fortemente recomendada, a RP tem sido subutilizada havendo um baixo índice de indicações. Objetivo: Identificar as barreiras e os facilitadores para o encaminhamento de pacientes com DPOC à RP e à prática de atividade física. Métodos: Estudo qualitativo, realizado com médicos atuantes na atenção primária à saúde (APS) e uso de entrevistas semiestruturadas. As entrevistas foram gravadas e transcritas literalmente e submetidas a análise de conteúdo. Itens (trechos) identificados nos discursos e relacionados ao encaminhamento de pacientes com DPOC à RP e à prática de atividade física foram classificados como barreiras ou facilitadores. Tal classificação se baseou entre os quatorze domínios da Theoretical Domains Framework (TDF) e suas definições para identificar determinantes de comportamento entre os participantes relevantes para a mudança na prática clínica. Resultados: Setecentos e cinquenta e seis itens foram identificados nos discursos de vinte e um participantes e classificados como sendo barreiras (n= 279, 37%) ou facilitadores (n= 477, 63%) relacionados principalmente aos domínios da TDF de "Conhecimento" (n= 245, 32%), "Contexto e recursos ambientais" (n= 124, 16%) e "Papel e identidade social/profissional" (n= 107, 14%). Conclusão: As principais barreiras identificadas foram relacionadas aos programas de RP devido ao conhecimento restrito dos profissionais médicos sobre programas de RP, a disponibilidade reduzida de locais que oferecem estes programas e as dificuldades de acesso dos pacientes à RP. Os principais facilitadores identificados foram relacionados a orientação e o conhecimento pelos médicos sobre os benefícios da atividade física e a presença dos grupos de exercícios fornecidos na APS.


Introduction: Chronic obstructive pulmonary disease (COPD) has a high prevalence and entails high costs to health systems. Pulmonary rehabilitation (PR) is a non-pharmacological intervention that generates clinical benefits for patients and cost savings for the health system due to a reduced number of exacerbations and hospitalizations. Although strongly recommended, PR has been underutilized, with a low rate of indications. Objective: To identify barriers and facilitators for referring patients with COPD to PR and physical activity. Method: Qualitative study was carried out with medical staff working in primary health care using semi-structured interviews. The interviews were recorded, transcribed literally and underwent content analysis. Items (text excerpts) identified in the speeches and related to the referral of patients with COPD to PR and physical activity were classified according to as barriers or facilitators, and among the fourteen domains of the Theoretical Domains Framework (TDF) and its definitions; aiming to identify the determinants of behaviour which were relevant to change in clinical practice. Results: Seven hundred and fifty-six items were identified in the speeches of twenty-one participants and classified as barriers (n= 279, 37%) or facilitators (n= 477, 63%) mainly related to the TDF domains of "Knowledge" (n= 245, 32%), "Context and environmental resources" (n=124, 16%) and "Role and social/professional identity" (n= 107, 14%). Conclusion: The main barriers identified were related to referring patients PR due to lack of knowledge by medical staff about PR programs, the limited number of programs available, and the restricted access to PR program locations. The main facilitators were related to physical activity, mainly the medical staff's knowledge on physical activity benefits and availability of exercise group activities delivered at primary health care centres.

RESUMO

This study aimed to evaluate the joint involvement in dogs with visceral leishmaniasis by means of orthopedic physical examination, radiographic and computed tomographic (CT) findings. Of the 46 evaluated dogs, an overall of 91.3 % presented joint (carpal, tarsal, elbows, and stifle) abnormalities, observed on physical examination, radiography and/or CT. In 67.3 % of the dogs orthopedic examination showed no abnormalities. Among the 31 dogs with normal orthopedic examination, 61.3 % showed radiographic and CT findings suggestive of osteoarthritis, 25.8 % presented normal radiographs with abnormalities evidenced only on CT, while 12.9 % presented normal radiographs and CT imaging. From the 15 dogs with abnormal orthopedic examination, 80 % had abnormal radiographic and CT findings suggestive of osteoarthritis, while 20 % presented normal radiographs with abnormalities evidenced only in their CT. Radiographic and CT findings included evident trabecular pattern, subchondral bone sclerosis, osteolysis, mixed bone lesions (osteolytic-proliferative lesions), soft tissue swelling around the joint (edema), joint space narrowing, bone proliferation, osteophytes, bone cyst and cartilage flap. Based on CT results the most affected joints, among those assessed, were the tarsal (80.9 %), followed by stifle (78.5 %), carpal (64.2 %), and elbows (54.7 %). Except by one dog that presented only one stifle joint compromised, the other three joints presented bilateral abnormalities in all dogs.

RESUMO

For selected patients with advanced emphysema, bronchoscopic lung volume reduction with one-way valves can lead to clinically relevant improvements of airflow obstruction, hyperinflation, exercise capacity, and quality of life. The most common complication of this procedure is pneumothorax with a prevalence of up to ±34% of the treated patients. Patients who develop a pneumothorax also experience meaningful clinical benefits once the pneumothorax is resolved. Timely resolution of a post-valve treatment pneumothorax requires skilled and adequate pneumothorax management. This expert panel statement is an updated recommendation of the 2014 statement developed to help guide pneumothorax management after valve placement. Additionally, mechanisms for pneumothorax development, risk assessment, prevention of pneumothorax, and outcomes after pneumothorax are addressed. This recommendation is based on a combination of the current scientific literature and expert opinion, which was obtained through a modified Delphi method.

RESUMO

This prospective, comparative, randomized, horizontal, and double-blind clinical study investigated the clinical efficacy of leucocyte-poor platelet-rich plasma (PRP, n=8) or allogeneic adipose-derived stem cells (ADSC, n=8) in dogs with bilateral degenerative hip joint disease (DHJD). Sixteen dogs were treated with two intra-articular injections of PRP or ADSCs, within a 30-day interval. The Canine Brief Pain Inventory (CBPI), the Helsinki Chronic Pain Index (HCPI), and Visual Analogue Scales for pain (VAS-pain) and locomotion (VAS-loc) were assessed by the dog owners. Analysis-of-gait using a force plate, response to palpation (VAS-palp), and the descriptive numerical scale for pain (DNS) were measured by a veterinarian. The assessments were performed before (baseline), 30 and 60 days after the first treatment. Data were analyzed using the unpaired t test, paired Wilcoxon test, Fisher's exact test, and Mann-Whitney and Friedman tests (P<0.05). Compared with baseline HCPI, CBPI, VAS-pain, and VAS-palp scores reduced 41%, 52%, 51%, and 48% (P=0.0001-0.03) at 60 days in the ADSC group. In PRP-treated dogs, CBPI, VAS-loc, and DNS scores decreased by 43%, 43%, and 33% at 60 days, respectively (P=0.0003-0.011). Based on CBPI data, the rate of success at 60 days was 75% and 25% in the ADSC and PRP groups (P=0.13), respectively. Both therapies were apparently safe and effective to reduce chronic pain in dogs with bilateral DHJD during a 60-day period. However, a trend towards greater improvement was provided by the ADSC treatment.

RESUMO

Introdução: A asma é uma doença respiratória caracterizada por sintomas como sibilo à ausculta pulmonar, dispneia e tosse, causados por limitação variável ao fluxo aéreo expiratório. A prática de atividades física pode auxiliar o controle da doença. Objetivo: Investigar o nível de atividade física de asmáticos adultos, e como estes indivíduos reportam receber orientação dos profissionais de saúde quanto à realização de atividade física. Método: Este estudo de métodos mistos foi realizado com indivíduos asmáticos, com idade superior a 18 anos. Os participantes realizaram teste de função pulmonar, responderam questionários sobre atividade física e entrevista semiestruturada. A entrevista foi realizada com questões voltadas ao tema central da pesquisa, as respostas foram transcritas de forma literal e analisadas por meio de metodologia da análise de conteúdo. Resultados: Vinte e cinco indivíduos participaram do estudo, a maioria do sexo feminino (n = 18; 72,0%) e idade média de 36 anos. A maioria dos indivíduos eram "irregularmente ativos" dos tipos A e B (n = 13; 52,0%). Foram identificados sete temas principais nos discursos: "conhecimento sobre os efeitos da atividade física regular" (n = 23; 92,0%), "atividade física específica para pacientes asmáticos" (n = 21; 84,0%), e "influência da orientação de um profissional de saúde" (n = 20; 80,0%). Conclusão: Os indivíduos asmáticos reportaram receber orientações dos profissionais de saúde quanto aos benefícios da prática regular de atividade física. Porém, estas informações podem ser insuficientes quanto ao tipo e frequência dos exercícios, modalidades apropriadas, manejo de possíveis sintomas durante ou após a prática da atividade e como preveni-los. Orientações adequadas sobre a prática da atividade regular para indivíduos asmáticos podem contribuir para o automanejo da doença.


Introduction: Asthma is a respiratory disease characterized by symptoms of wheezing, dyspnea, and cough, caused by some degree of limitation to expiratory airflow. Engagement in regular physical activity can help control the disease. Objective: To assess physical activity levels in asthmatic adults and to investigate how these individuals report guidance received from health professionals regarding physical activity. Method: This mixed-methods study included asthmatic adults aged 18 years or over. Participants underwent pulmonary function tests, completed physical activity questionnaires, and did a semistructured interview. The interview consisted of questions focused on the central topic of interest, and responses were transcribed literally and then analyzed using content analysis methods. Results: Twenty-five individuals participated in the study, most were female (n=18; 72.0%), and mean age was 36 years. Most individuals were classified as "irregularly active" (n=8; 32.0%). Seven main topics were identified in content analysis, including "knowledge about the effects of regular physical activity" (n=23; 92.0%), "specific physical activity for asthmatic patients" (n=21; 84.0%), and "influence of guidance from a health professional" (n=20; 80.0%). Conclusion: Asthmatic individuals reported having received guidance from health professionals regarding the benefits of engagement in regular physical activity. However, there is insufficient information regarding type and frequency of exercise, appropriate modalities, and management of possible symptoms during or after the activity and how to prevent them. Adequate guidance on regular activity for asthmatic individuals may contribute to self-management of the disease.

RESUMO

ABSTRACT Pain control is essential in dental practice, and can be accomplished through various techniques. This study seeks to compare atraumatic and conventional anesthetic techniques, applied during surgeries to remove upper third molars. The endpoints evaluated were pain indices, patient satisfaction and anesthetic efficacy. A random parallel split-mouth clinical trial was conducted with 14 patients. Group A received atraumatic anesthesia without a needle (Comfort-in®) and group B received conventional anesthesia by blocking the posterior superior alveolar nerve (PSAN) and Greater Palatine Nerve (GPN). A Visual Analogue Scale (VAS) was used to assess pain. A significantly (p<0.001) lower perception ofpain was observed among individuals who received the atraumatic technique. In 71% of cases, it was necessary to supplement the anesthesia during the procedure. Even considering the need for additional anesthesia, the Comfort-in® technique was more accepted by patients with regard to pain perception than the conventional manual technique.


RESUMO O controle da dor é fundamental na prática odontológica, po-dendo ser feito a partir de várias técnicas. Este estudo visa comparar as técnicas anestésicas atraumática e convencional, aplicadas durante cirurgias para remover terceiros molares superiores. Os pontos avaliados foram índice de dor, satisfaqao do paciente e eficácia anestésica. Um ensaio clínico randomi-zado, paralelo, boca dividida, foi conduzido com 14 participantes. O grupo A recebeu anestesia atraumática sem agulha (Comfort-in®) e o grupo B anestesia convencional por meio de bloqueio do nervo alveolar superior posterior (NASP) e nervo palatino maior (NPM). Uma Escala Visual Analógica (EVA) foi utilizada para avaliar a dor. Uma significativa (p<0,001) menor percepção de dor entre os individuos que receberam a técnica atraumática foi observada. Em 71% dos casos, fez-se necessària a complementação da anestesia durante a realiza-ção do procedimento. Mesmo considerando a necessidade de anestesia adicional, a técnica empregando o sistema Comfort-in® teve maior aceitação dos pacientes quando comparado à técnica manual convencional, no que se refere a percepção de dor, ainda que considerando a necessidade de complementação da anestesia.

RESUMO

ABSTRACT Objective Prematurity and low birth weight predispose preterm infants to cardiovascular disease in later life. Is the metabolic profile of these children impacted by the relation between birth weight and gestational age (GA)? This study aimed to evaluate whether the relationship between birth weight and GA of preterm infants has a positive correlation with the metabolic profile from birth to the sixth month of corrected age. Subjects and methods This is a longitudinal, prospective study with a cohort of 70 preterm and 54 term infants, who were enrolled in the study and shared into two groups: Appropriate for GA (AGA) and Small for GA (SGA), both classified at birth by Fenton and Kim curves. Longitudinal evaluation of anthropometry measures and blood samples of total cholesterol, glucose, triglycerides, and insulin were collected at birth, NICU discharge, and the sixth month of corrected age. Data were analyzed using descriptive and inferential statistical analysis (ANOVA, Fisher test, Shapiro-Wilk, and Cochran test). The effect size was 0.15, power was 0.92, and confidence interval 95%. Results No significant statistical differences were observed in relation to biochemical tests between AGA and SGA groups. However, a significant increase in triglyceride results above the reference values for age in the SGA group was observed throughout the follow-up. Conclusions Changes observed in the preterm infant metabolic profile show no correlation with adequacy of birth weight. Preterm lipid profile requires continuous evaluation at follow-up, due to the increased cardiovascular risk in later life.

RESUMO

The antioxidant and anti-inflammatory properties of Malpighia emarginata D.C (acerola) and Camellia sinensis L. (green tea) have been studied, particularly as an alternative in medicinal approach for different physio pathological conditions. Here we develop an powder blend formulated with both Malpighia emarginata D.C and Camellia sinensis L. which have in the composition higher content of ascorbic acid and epigallatocathechin-3-gallate respectively. Using different conditions for microencapsulation of biocompounds, we performed the powder production through spray-drying process. After, we evaluate the antioxidant and anti-inflammatory properties of blends formulated with Malpighia emarginata D.C and Camellia sinensis L. in an in vitro model of inflammation, using LPS-stimulated RAW-264.7 macrophage cell line. We observed that co-treatment with blends was able to modulate the redox parameters in cells during the in vitro inflammatory response. Moreover, the co-treatment with blends were able to modulate inflammatory response by altering the secretion of cytokines IL-1ß, IL-6, IL-10, and TNF-α. Taken together, our results demonstrate for the first time the synergistic effects antioxidant and anti-inflammatory of Malpighia emarginata D.C and Camellia sinensis L. These results warrant further use of the blend powder for use in the products to heath beneficial, principally in terms of prevention of chronic diseases.
