RESUMO

Resumo Introdução: A gestação configura-se como um acontecimento único e memorável para a vida de uma mulher. A gravidez de alto risco é uma experiência estressante em razão dos riscos a que estão submetidos a mãe e o bebê e devido às mudanças que afetam negativamente o seu equilíbrio emocional. Objetivo: Identificar os sentimentos vivenciados pela gestante frente à gravidez de alto risco. Método: Descritivo e exploratório com abordagem qualitativa, com amostra por conveniência composta por mulheres com gestação de alto risco, selecionadas de acordo com a disponibilidade do serviço de internamento, até a saturação das entrevistas. A coleta dos dados foi realizada em um período de dois meses através de entrevistas guiadas por um roteiro. Os dados foram analisados por meio da técnica de análise de conteúdo segundo Minayo. Resultados: Fizeram parte 37 mulheres. Os resultados foram oeganizados nas categorias: Como se deu o diagnóstico de alto risco; Sentimentos ao descobrir que a gestação é/era de risco; Sentimentos em relação ao apoio familiar acerca da gestação de alto risco. Os sentimentos relatados pelas gestantes e puérperas que conviveram com a gravidez de alto risco, deixam evidentes os impactos que este evento traz não somente na saúde física sobretudo para a emocional, deixando as gestantes fragilizadas. Conclusão: Assim, o estudo nos permitiu perceber que os sentimentos vivenciados nesse processo podem interfir na vida dessas mulheres, e de forma negativa. Mas, que apesar dessa situação, estas expressam sentimentos ambíguos, pois mesmo com o risco gestacional, muitas mostram-se felizes pela dádiva de ser mãe.


Resumen Introducción: El embarazo se considera un evento único y memorable en la vida de una mujer. El embarazo de alto riesgo es una experiencia estresante debido a los riesgos a los que están expuestas tanto la madre como su bebé y a los cambios que afectan negativamente su equilibrio emocional. Objetivo: Identificar los sentimientos experimentados por las mujeres embarazadas frente a un embarazo de alto riesgo. Metodología: Descriptivo y exploratorio con enfoque cualitativo, con una muestra a conveniencia compuesta por mujeres con embarazos de alto riesgo, seleccionadas según la disponibilidad del servicio de hospitalización, hasta la saturación de las entrevistas. La recopilación de datos se llevó a cabo durante un período de dos meses a través de entrevistas guiadas. Los datos fueron analizados utilizando la técnica de análisis de contenido según Minayo. Resultados: Participaron 37 mujeres y los resultados se organizaron en las siguientes categorías: cómo se realizó el diagnóstico de alto riesgo; sentimientos al descubrir que el embarazo era de riesgo; sentimientos con respecto al apoyo familiar en relación con el embarazo de alto riesgo. Los sentimientos relatados por las mujeres embarazadas y posparto que vivieron un embarazo de alto riesgo evidencian los impactos que tiene este evento no solo en la salud física sino, especialmente, en el bienestar emocional, pues deja a las mujeres embarazadas en un estado de vulnerabilidad. Conclusión: El estudio nos permitió darnos cuenta de que los sentimientos experimentados en este proceso pueden interferir en la vida de estas mujeres de manera negativa. Sin embargo, a pesar de esta situación, muchas de ellas expresan sentimientos ambiguos, porque, incluso con el riesgo gestacional, están agradecidas por el regalo de la maternidad.


Abstract Introduction: Pregnancy is considered a unique and memorable event in a woman's life. High-risk pregnancy is a stressful experience due to the risks to which the mother and the baby are exposed, and due to the changes that negatively affect their emotional balance. Objective: To identify the feelings experienced by pregnant women facing high-risk pregnancy. Method: Descriptive and exploratory, employing a qualitative approach, the study featured a convenience sample of women with high-risk pregnancies, selected based on inpatient service availability, until interview saturation was achieved. Data collection was conducted over a two-month period through scripted interviews. Data analysis was performed utilizing Minayo's content analysis technique. Results: Thirty-seven women participated in the study. The results were categorized as follows: How the high-risk diagnosis was determined; Feelings upon discovering the pregnancy was high-risk; Feelings regarding family support regarding the high-risk pregnancy. The feelings reported by pregnant and postpartum women who experienced high-risk pregnancies clearly reveal the impacts this event has, not only on physical health, but especially on emotional well-being, leaving the pregnant women in a vulnerable state. Conclusion: The study allowed us to realize that the feelings experienced in this process can negatively interfere in the lives of these women. However, despite this situation, many of them express mixed feelings, because even with the gestational risk, they are grateful for the gift of motherhood.

RESUMO

Introduction: Currently, Chronic Obstructive Pulmonary Disease (COPD) has a high impact on morbidity and mortality worldwide. The increase of CD4+, CD8+ cells expressing NF-κB, STAT4, IFN-γ and perforin are related to smoking habit, smoking history, airflow rate, obstruction and pulmonary emphysema. Furthermore, a deficiency in CD4+CD25+Foxp3+ regulatory T cells (Tregs) may impair the normal function of the immune system and lead to respiratory immune disease. On the other hand, the anti-inflammatory cytokine IL-10, produced by Treg cells and macrophages, inhibits the synthesis of several pro-inflammatory cytokines that are expressed in COPD. Therefore, immunotherapeutic strategies, such as Photobiomodulation (PBM), aim to regulate the levels of cytokines, chemokines and transcription factors in COPD. Consequently, the objective of this study was to evaluate CD4+STAT4 and CD4+CD25+Foxp3+ cells as well as the production of CD4+IFN- γ and CD4+CD25+IL-10 in the lung after PBM therapy in a COPD mice model. Methods: We induced COPD in C57BL/6 mice through an orotracheal application of cigarette smoke extract. PMB treatment was applied for the entire 7 weeks and Bronchoalveolar lavage (BAL) and lungs were collected to study production of IFN- γ and IL-10 in the lung. After the last administration with cigarette smoke extract (end of 7 weeks), 24 h later, the animals were euthanized. One-way ANOVA followed by NewmanKeuls test were used for statistical analysis with significance levels adjusted to 5% (p < 0.05). Results: This result showed that PBM improves COPD symptomatology, reducing the number of inflammatory cells (macrophages, neutrophils and lymphocytes), the levels of IFN-γ among others, and increased IL-10. We also observed a decrease of collagen, mucus, bronchoconstriction index, alveolar enlargement, CD4+, CD8+, CD4+STAT4+, and CD4+IFN-γ+ cells. In addition, in the treated group, we found an increase in CD4+CD25+Foxp3+ and CD4+IL-10+ T cells. Conclusion: This study suggests that PBM treatment could be applied as an immunotherapeutic strategy for COPD.

RESUMO

BACKGROUND: Photobiomodulation has exhibited promise in mitigating the local effects induced by Bothrops snakebite envenoming; however, the mechanisms underlying this protection are not yet fully understood. Herein, the effectiveness of photobiomodulation effects on regenerative response of C2C12 myoblast cells following exposure to Bothrops jararacussu venom (BjsuV), as well as the mechanisms involved was investigated. METHODOLOGY/PRINCIPAL FINDINGS: C2C12 myoblast cells were exposed to BjsuV (12.5 µg/mL) and irradiated once for 10 seconds with laser light of 660 nm (14.08 mW; 0.04 cm2; 352 mW/cm2) or 780 nm (17.6 mW; 0.04 cm2; 440 mW/ cm2) to provide energy densities of 3.52 and 4.4 J/cm2, and total energies of 0.1408 and 0.176 J, respectively. Cell migration was assessed through a wound-healing assay. The expression of MAPK p38-α, NF-Кß, Myf5, Pax-7, MyoD, and myogenin proteins were assessed by western blotting analysis. In addition, interleukin IL1-ß, IL-6, TNF-alfa and IL-10 levels were measured in the supernatant by ELISA. The PBM applied to C2C12 cells exposed to BjsuV promoted cell migration, increase the expression of myogenic factors (Pax7, MyF5, MyoD and myogenin), reduced the levels of proinflammatory cytokines, IL1-ß, IL-6, TNF-alfa, and increased the levels of anti-inflammatory cytokine IL-10. In addition, PBM downregulates the expression of NF-kB, and had no effect on p38 MAKP. CONCLUSION/SIGNIFICANCE: These data demonstrated that protection of the muscle cell by PBM seems to be related to the increase of myogenic factors as well as the modulation of inflammatory mediators. PBM therapy may offer a new therapeutic strategy to address the local effects of snakebite envenoming by promoting muscle regeneration and reducing the inflammatory process.

RESUMO

Necrosis is common in skin flap surgeries. Photobiomodulation, a noninvasive and effective technique, holds the potential to enhance microcirculation and neovascularization. As such, it has emerged as a viable approach for mitigating the occurrence of skin flap necrosis. The aim of this systematic review was to examine the scientific literature considering the use of photobiomodulation to increase skin-flap viability. The preferred reporting items for systematic reviews and meta-analyses (PRISMA), was used to conducted systematic literature search in the databases PubMed, SCOPUS, Elsevier and, Scielo on June 2023. Included studies investigated skin-flap necrosis employing PBMT irradiation as a treatment and, at least one quantitative measure of skin-flap necrosis in any animal model. Twenty-five studies were selected from 54 original articles that addressed PBMT with low-level laser (LLL) or light-emitting diode (LED) in agreement with the qualifying requirements. Laser parameters varied markedly across studies. In the selected studies, the low-level laser in the visible red spectrum was the most frequently utilized PBMT, although the LED PBMT showed a similar improvement in skin-flap necrosis. Ninety percent of the studies assessing the outcomes of the effects of PBMT reported smaller areas of necrosis in skin flap. Studies have consistently demonstrated the ability of PBMT to improve skin flap viability in animal models. Evidence suggests that PBMT, through enhancing angiogenesis, vascular density, mast cells, and VEGF, is an effective therapy for decrease necrotic tissue in skin flap surgery.

RESUMO

BACKGROUND: Aldosterone plays a key role in the neurohormonal drive of heart failure. Systematic prioritization of drug targets using bioinformatics and database-driven decision-making can provide a competitive advantage in therapeutic R&D. This study investigated the evidence on the druggability of these aldosterone targets in heart failure. METHODS: The target disease predictability of mineralocorticoid receptors (MR) and aldosterone synthase (AS) in cardiac failure was evaluated using Open Targets target-disease association scores. The Open Targets database collections were downloaded to MongoDB and queried according to the desired aggregation level, and the results were retrieved from the Europe PMC (data type: text mining), ChEMBL (data type: drugs), Open Targets Genetics Portal (data type: genetic associations), and IMPC (data type: genetic associations) databases. The target tractability of MR and AS in the cardiovascular system was investigated by computing activity scores in a curated ChEMBL database using supervised machine learning. RESULTS: The medians of the association scores of the MR and AS groups were similar, indicating a comparable predictability of the target disease. The median of the MR activity scores group was significantly lower than that of AS, indicating that AS has higher target tractability than MR [Hodges-Lehmann difference 0.62 (95%CI 0.53-0.70, p < 0.0001]. The cumulative distributions of the overall multiplatform association scores of cardiac diseases with MR were considerably higher than with AS, indicating more advanced investigations on a wider range of disorders evaluated for MR (Kolmogorov-Smirnov D = 0.36, p = 0.0009). In curated ChEMBL, MR had a higher cumulative distribution of activity scores in experimental cardiovascular assays than AS (Kolmogorov-Smirnov D = 0.23, p < 0.0001). Documented clinical trials for MR in heart failures surfaced in database searches, none for AS. CONCLUSIONS: Although its clinical development has lagged behind that of MR, our findings indicate that AS is a promising therapeutic target for the treatment of cardiac failure. The multiplatform-integrated identification used in this study allowed us to comprehensively explore the available scientific evidence on MR and AS for heart failure therapy.

RESUMO

The introduction of immunotherapy has brought about a paradigm shift in the management of advanced non-small cell lung cancer (NSCLC). It has not only significantly improved the prognosis of patients but has also become a cornerstone of treatment, particularly in those without oncogenic driver mutations. Immune checkpoint inhibitors (ICIs) play a crucial role in the treatment of lung cancer and can be classified into two main groups: Anti-cytotoxic T lymphocyte antigen-4 (Anti-CTLA-4) and anti-T-cell receptor programmed cell death-1 or its ligand (Anti-PD-1 and Anti-PD-L1). Certainly, the landscape of approved first line immunotherapeutic approaches has expanded to encompass monotherapy, immunotherapy-exclusive protocols, and combinations with chemotherapy. The complexity of decision-making in this realm arises due to the absence of direct prospective comparisons. However, a thorough analysis of the long-term efficacy and safety data derived from pivotal clinical trials can offer valuable insights into optimizing treatment for different patient subsets. Moreover, ongoing research is investigating emerging biomarkers and innovative therapeutic strategies that could potentially refine the current treatment approach even further. In this comprehensive review, our aim is to highlight the latest advances in immunotherapy for advanced NSCLC, including the mechanisms of action, efficacy, safety profiles, and clinical significance of ICI.

RESUMO

Blood pressure (BP) is the main biomarker for monitoring patients, as its lack of control above values considered normal is a modifiable risk factor for target organ damage. The aim of this study is to evaluate the accuracy of the wearable electronic device photoplethysmography technology (PPG) Samsung Galaxy Watch 4 in determining BP in young patients compared to manual and automatic methods of BP determination. This is a quantitative and cross-sectional study, following validation protocols for wearable devices and BP measurement. It was carried out with twenty healthy young adults, in which BP was measured using four instruments, namely, standard sphygmomanometer device (manual), automatic arm oscillometric device (reference), wrist oscillometric device, and Smartwatch PPG. Eighty systolic blood pressure (SBP) and diastolic blood pressure (DBP) readings were observed. SBP means manual 118 ± 2.20,arm 113 ± 2.54, wrist 118 ± 2.51, and PPG (smartwatch) 113 ± 2.58. Among means, arm and PPG difference is 0.15, arm and wrist 4.95, arm and manual 4.45 wrist with PPG. The mean DBP manual 76.7 ± 1.84, arm 73.6 ± 1.92, wrist 79.3 ± 1.87, and PPG 72.2 ± 1.38. Among means, the difference between the arm and PPG is 1.4 and arm and hand 3.5 mmHg. The correlation shows PPG with manual, arm, and wrist. There was a strong SBP correlation and a moderate DBP correlation between the methods tested, evidencing the accuracy of the PPG smartwatch in relation to the reference method.

RESUMO

Prenatal alcohol exposure (PAE) impairs fetal development. Alcohol consumption was shown to modulate the renin-angiotensin system (RAS). This study aimed to analyze the effects of PAE on the expression of the renin-angiotensin system (RAS) and kallikrein-kinin system (KKS) peptide systems in the hippocampus and heart of mice of both sexes. C57Bl/6 mice were exposed to alcohol during pregnancy at a concentration of 10% (v/v). On postnatal day 45 (PN45), mouse hippocampi and left ventricles (LV) were collected and processed for messenger RNA (mRNA) expression of components of the RAS and KKS. In PAE animals, more pronounced expression of AT1 and ACE mRNAs in males and a restored AT2 mRNA expression in females were observed in both tissues. In LV, increased AT2, ACE2, and B2 mRNA expressions were also observed in PAE females. Furthermore, high levels of H2O2 were observed in males from the PAE group in both tissues. Taken together, our results suggest that modulation of the expression of these peptidergic systems in PAE females may make them less susceptible to the effects of alcohol.
