Aesthetic Radiofrequency Associated with Rosmarinus officinalis Supplementation is Safe and Reduces Oxidative Stress in Women: Randomized, and Double-Blind Clinical Trial.

The objective were to evaluate the effects of supplementation of standardized dry extract of Rosmarinus officinalis (RO) and the application of aesthetic radiofrequency on the oxidative stress markers catalase (CAT), superoxide dismutase (SOD), non-protein thiols (NP-SH), and thiobarbituric acid reactive species (TBARS) and the biochemical markers triglycerides, total cholesterol, high density lipoprotein (HDL) cholesterol, glutamic-oxaloacetic transaminase (TGO/AST), pyruvic-glutamic transaminase (TGP/ALT), gamma glutamyl transpeptidase (gamma-GT), and creatinine. This study included 32 women received the aesthetic therapy to reduce localized fat. They were divided into the control group (n = 8) receiving placebo capsules and the intervention group (n = 24) subdivided into Group A, B, and C, each with eight members receiving supplementation with 100, 500, and 1000 mg/day of standardized dry extract of RO, respectively. The Universal Trial Number (UTN) - U1111-1274-6255. Supplementation with RO (500 mg/day) demonstrated a reduction in oxidative stress (quantified with through a significant increase in NP-SH and a reduction in SOD and CAT enzymes). The radiofrequency aesthetic treatment did not promote an increase in oxidative stress; however, it caused significant changes in total cholesterol, HDL cholesterol, and creatinine. RO is a plant with antioxidant effects and its oral consumption is safe in selected women subjects in hepatic and renal markers.

Clinical Profile and Course of Patients with Acute Respiratory Distress Syndrome due to COVID-19 in a Middle-Income Region in Mexico.

Introduction: COVID-19 leads to severe clinical complications that culminate in respiratory failure and acute respiratory distress syndrome (ARDS). Despite reports of some comorbidities that contribute to the development of COVID-19-mediated ARDS, there is great variation in mortality rates among critical COVID-19 patients in the world. To date, no studies have described the incidence and comorbidities associated with ARDS due to COVID-19 in the northeastern region of Mexico. Aim of the study: To describe patients diagnosed with ARDS due to COVID-19 in the northeastern region of Mexico, as well as its variations in comparison with other regions of the country. Material and Methods: We conducted a prospective and observational study in a tertiary care center in Northeastern Mexico. All patients diagnosed with SARS-CoV-2 infection and requiring management in the intensive care unit were included. We developed a database that was updated daily with the patients' demographic information, pre-existing diseases, disease severity, and clinical variables. Results: The incidence of ARDS secondary to COVID-19 in HRAEV was high in comparison with other reports. Diabetes mellitus was the risk factor most associated with COVID-19-mediated ARDS. Conclusion: Based on our findings and those previously reported in the literature, there are differences that we discuss between northeastern and central Mexico, and analyze other areas evaluated around the world.

Exploring the biofilm inhibitory potential of Candida sp. UFSJ7A glycolipid on siliconized latex catheters.

Biosurfactants, sustainable alternatives to petrochemical surfactants, are gaining attention for their potential in medical applications. This study focuses on producing, purifying, and characterizing a glycolipid biosurfactant from Candida sp. UFSJ7A, particularly for its application in biofilm prevention on siliconized latex catheter surfaces. The glycolipid was extracted and characterized, revealing a critical micellar concentration (CMC) of 0.98 mg/mL, indicating its efficiency at low concentrations. Its composition, confirmed through Fourier transform infrared spectroscopy (FT-IR) and thin layer chromatography (TLC), identified it as an anionic biosurfactant with a significant ionic charge of -14.8 mV. This anionic nature contributes to its biofilm prevention capabilities. The glycolipid showed a high emulsification index (E24) for toluene, gasoline, and soy oil and maintained stability under various pH and temperature conditions. Notably, its anti-adhesion activity against biofilms formed by Escherichia coli, Enterococcus faecalis, and Candida albicans was substantial. When siliconized latex catheter surfaces were preconditioned with 2 mg/mL of the glycolipid, biofilm formation was reduced by up to 97% for E. coli and C. albicans and 57% for E. faecalis. These results are particularly significant when compared to the efficacy of conventional surfactants like SDS, especially for E. coli and C. albicans. This study highlights glycolipids' potential as a biotechnological tool in reducing biofilm-associated infections on medical devices, demonstrating their promising applicability in healthcare settings.

Production and characterization of the lipopeptide with anti-adhesion for oral biofilm on the surface of titanium for dental implants.

Titanium implants are subject to bacterial adhesion and peri-implantitis induction, and biosurfactants bring a new alternative to the fight against infections. This work aimed to produce and characterize the biosurfactant from Bacillus subtilis ATCC 19,659, its anti-adhesion and antimicrobial activity, and cell viability. Anti-adhesion studies were carried out against Streptococcus sanguinis, Staphylococcus aureus, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Proteus mirabilis as the minimum inhibitory concentration and the minimum bactericidal concentration. Cell viability was measured against osteoblast and fibroblast cells. The biosurfactant was classified as lipopeptide, with critical micelle concentration at 40 µg mL- 1, and made the titanium surface less hydrophobic. The anti-adhesion effect was observed for Staphylococcus aureus and Streptococcus sanguinis with 54% growth inhibition and presented a minimum inhibitory concentration of 15.7 µg mL- 1 for Streptococcus sanguinis and Aggregatibacter actinomycetemcomitans. The lipopeptide had no cytotoxic effect and demonstrated high potential application against bacterial biofilms.

Antibacterial and Antiviral Properties of Chenopodin-Derived Synthetic Peptides.

Antimicrobial peptides have been developed based on plant-derived molecular scaffolds for the treatment of infectious diseases. Chenopodin is an abundant seed storage protein in quinoa, an Andean plant with high nutritional and therapeutic properties. Here, we used computer- and physicochemical-based strategies and designed four peptides derived from the primary structure of Chenopodin. Two peptides reproduce natural fragments of 14 amino acids from Chenopodin, named Chen1 and Chen2, and two engineered peptides of the same length were designed based on the Chen1 sequence. The two amino acids of Chen1 containing amide side chains were replaced by arginine (ChenR) or tryptophan (ChenW) to generate engineered cationic and hydrophobic peptides. The evaluation of these 14-mer peptides on Staphylococcus aureus and Escherichia coli showed that Chen1 does not have antibacterial activity up to 512 µM against these strains, while other peptides exhibited antibacterial effects at lower concentrations. The chemical substitutions of glutamine and asparagine by amino acids with cationic or aromatic side chains significantly favoured their antibacterial effects. These peptides did not show significant hemolytic activity. The fluorescence microscopy analysis highlighted the membranolytic nature of Chenopodin-derived peptides. Using molecular dynamic simulations, we found that a pore is formed when multiple peptides are assembled in the membrane. Whereas, some of them form secondary structures when interacting with the membrane, allowing water translocations during the simulations. Finally, Chen2 and ChenR significantly reduced SARS-CoV-2 infection. These findings demonstrate that Chenopodin is a highly useful template for the design, engineering, and manufacturing of non-toxic, antibacterial, and antiviral peptides.

Blood biochemical, hormonal, and hematological responses of native sheep submitted to different environmental conditions.

The aim of this study was to evaluate the biochemical, hormonal, and hematological blood responses of native sheep subjected to five temperatures (20°, 24°, 28°, 32°, and 36 °C), using 24 sheep of the following breeds: Santa Inês (SI), Morada Nova (MN), Soinga (SO) and no defined racial pattern (NDRP), kept in collective pens inside the climatic chamber. The experimental design was completely randomized, in a 5 × 4 factorial scheme (5 temperatures and 4 breeds) with 6 animals of each breed at each temperature. There was interaction for urea (P < .0001), glucose (P < .0001), cholesterol (P < .0001), and magnesium (P < .0001) as a function of breed and air temperature. Urea (P = .001), glucose (P < .0001), triglycerides (P = .033), cholesterol (P = .004), and magnesium (P < .0001) showed differences according to breed. It was observed that T4 (P < .0001) and cortisol (P < .0001) showed an interaction between breed and temperature, while T4 (P = .001) and cortisol (P = .001) an effect of breed. The highest magnesium concentration was observed in MN, and the lowest was in NDRP, SO, and SI, which are statistically similar, and SI and NDRP are statistically similar. The hormones showed a significant effect (P < .0001) for temperature, where cortisol increased, and thyroid hormones decreased with increasing temperature. Temperatures of 32° and 36 °C contribute to changes in blood, hormone, and hematological biochemical responses of native sheep.

Giants of the Amazon: How does environmental variation drive the diversity patterns of large trees?

For more than three decades, major efforts in sampling and analyzing tree diversity in South America have focused almost exclusively on trees with stems of at least 10 and 2.5 cm diameter, showing highest species diversity in the wetter western and northern Amazon forests. By contrast, little attention has been paid to patterns and drivers of diversity in the largest canopy and emergent trees, which is surprising given these have dominant ecological functions. Here, we use a machine learning approach to quantify the importance of environmental factors and apply it to generate spatial predictions of the species diversity of all trees (dbh ≥ 10 cm) and for very large trees (dbh ≥ 70 cm) using data from 243 forest plots (108,450 trees and 2832 species) distributed across different forest types and biogeographic regions of the Brazilian Amazon. The diversity of large trees and of all trees was significantly associated with three environmental factors, but in contrasting ways across regions and forest types. Environmental variables associated with disturbances, for example, the lightning flash rate and wind speed, as well as the fraction of photosynthetically active radiation, tend to govern the diversity of large trees. Upland rainforests in the Guiana Shield and Roraima regions had a high diversity of large trees. By contrast, variables associated with resources tend to govern tree diversity in general. Places such as the province of Imeri and the northern portion of the province of Madeira stand out for their high diversity of species in general. Climatic and topographic stability and functional adaptation mechanisms promote ideal conditions for species diversity. Finally, we mapped general patterns of tree species diversity in the Brazilian Amazon, which differ substantially depending on size class.

Brazilian Society of Surgical Oncology: Guidelines for the management of anal canal cancer.

BACKGROUND: Anal canal squamous cell carcinoma (SCC) is a relatively uncommon neoplasia, and it is mostly a local-regional cancer, of low metastatic potential (only 15%), resulting in cure in most cases treated with definitive chemoradiation. On the other hand, its incidence has been steadily increasing over the last decades, which makes it an important public health problem. In an effort to provide surgeons and oncologists who treat patients with anal cancer with the most updated information based on the best scientific evidence, the Brazilian Society of Surgical Oncology (SBCO) has produced the present guideline for the management of anal canal SCC, focused on the main topics related to daily clinical practice. OBJECTIVES: The SBCO developed the present guidelines to provide recommendations on the main topics related to the management of anal canal squamous cell carcinoma (SCC) based on current scientific evidence. METHODS: Between October 2022 and January 2023, 14 experts met to develop the guidelines for the management of anal canal cancer. A total of 30 relevant topics were distributed among the participants. The methodological quality of a final list with 121 sources was evaluated, all the evidence was examined and revised, and the management guidelines were formulated by the 14-expert committee. To reach a final consensus, all the topics were reviewed in a meeting that was attended by all the experts. RESULTS: The proposed guidelines contained 30 topics considered to be highly relevant in the management of anal canal cancer, covering subjects related to screening recommendations, preventive measures, tests required for diagnosing and staging, treatment strategies, response assessment after chemoradiotherapy, surgical technique-related aspects, and follow-up recommendations. In addition, screening and response assessment algorithms, and a checklist were proposed to summarize the important information and offer an updated tool to assist surgeons and oncologists who treat anal canal cancer and in providing the best care to their patients. CONCLUSION: These guidelines summarize recommendations based on the most current scientific evidence on relevant aspects of anal canal cancer management and are a practical guide to help surgeons and oncologists who treat anal canal cancer make the best therapeutic decisions.

Ensino da empatia em saúde: revisão integrativa / Teaching empathy in healthcare: an integrative review / Enseñar empatía en salud: una revisión integradora

Resumo Empatia pressupõe a capacidade e sobretudo a vontade de compreender o outro e se colocar em seu lugar. Considerando isso, espera-se que profissionais envolvidos em cuidados de saúde sejam mais empáticos e capazes de ler o mundo ao seu redor com olhar humanizado, crítico e reflexivo. Objetivou-se investigar, mediante revisão integrativa, o que tem sido discutido a respeito do ensino da empatia nos cursos de graduação da área da saúde nos últimos cinco anos. Foram selecionados 27 artigos das bases de dados MEDLINE e LILACS, por meio dos quais se identificou que a maioria dos estudos disponíveis foram realizados nas áreas de medicina e enfermagem. Além disso, constatou-se que, apesar de o tema empatia remeter à subjetividade, a metodologia quantitativa com aplicação de escalas padronizadas foi a mais utilizada para mensurar níveis de empatia e que, por fim, o ensino da empatia ocorreu por meio de metodologias ativas.

Abstract Empathy presupposes the ability and, most importantly, the willingness to understand others and put oneself in their place. Hence, health personnel are expected to be more empathetic and able to read the world around them with a humanized, critical, and reflexive look. This integrative review examines the studies on teaching empathy in undergraduate health programs published in the last five years. A total of 27 studies were selected from the MEDLINE and LILACS databases, most of which were published in the fields of medicine and nursing. Although a subjective element, most studies measured empathy using standardized scales (quantitative approach). Finally, empathy was taught using active methodologies.

Resumen La empatía es una capacidad, sobre todo una voluntad, de comprender al otro y de ponerse en su piel. Así se espera que los profesionales involucrados en el cuidado de la salud sean más empáticos y tengan una mirada humanizada, crítica y reflexiva sobre el mundo. Esta es una revisión integradora para identificar cómo se enseña la empatía en las carreras de graduación en el área de la salud en los últimos cinco años. Se seleccionaron 27 artículos de las bases de datos MEDLINE y LILACS, y se identificó que la mayoría de los estudios disponibles fueron de las áreas de Medicina y Enfermería. Se constató también que, aunque el tema de la empatía se refiera a la subjetividad, el método cuantitativo con la aplicación de escalas estandarizadas fue el más utilizado para medir los niveles de empatía y que la enseñanza de la empatía ocurrió por metodologías activas.

Gênero: (re)politizando a psicanálise / Gender: (re)politicizing psychoanalysis / Genre: (re)politiser la psychanalyse / Género: (re)politizando el psicoanálisis

Este texto tem por propósito, em primeiro lugar, construir uma reflexão acerca da ideia de que gênero, além de ser um problema de todos, inclusive da psicanálise e dos/das/des psicanalistas, é um conceito imprescindível para a escuta clínica no contemporâneo. Em segundo lugar, tem por objetivo apontar tarefas teóricas e clínico-políticas para que possamos, coletivamente, desobstruir a nossa escuta e ampliar o nosso horizonte ético e político, mas, mais do que isso, para que possamos perder o medo de abrir mão de velhos conceitos e criarmos coragem de escutar as demandas do nosso tempo, inventando novos rumos e, consequentemente, novos conceitos para as psicanálises.

The purpose of this text is, firstly, to build a reflection on the idea that gender, in addition to being a problem for everyone, including psychoanalysis and psychoanalysts, is an essential concept for clinical listening in the contemporary world. Secondly, it aims to point out theoretical and clinical-political tasks so that we can collectively clear our listening and broaden our ethical and political horizons, but more than that, so that we can lose the fear of giving up old concepts and create the courage to listen to the demands of our time, inventing new directions and, consequently, new concepts for psychoanalysis.

L'objet de ce texte est, dans un premier temps, de construire une réflexion sur l'idée que le genre, en plus d'être un problème pour tous, y compris la psychanalyse et les psychanalystes, est un concept essentiel pour l'écoute clinique dans le monde contemporain. Deuxièmement, il vise à souligner les tâches théoriques et clinico-politiques afin que nous puissions collectivement éclaircir notre écoute et élargir nos horizons éthiques et politiques, mais plus que cela, afin que nous puissions perdre la peur d'abandonner les vieux concepts et créer le courage écouter les exigences de notre temps, inventer de nouvelles directions et, par conséquent, de nouveaux concepts pour la psychanalyse.

Advance Directives: Knowledge of the Topic Among Psychiatrists.

Objective: Advance directives are becoming increasingly important as health technologies evolve. We sought to assess psychiatrists' knowledge of advance directives, as this knowledge is fundamental to the implementation and drafting of these personal documents. Methods: A previously published questionnaire that evaluated the knowledge of medical professors was used. The sample, composed of psychiatrists from Rio de Janeiro, Brazil, originated from a publicly available list. During the search process, the COVID-19 pandemic affected Brazil and the rest of the world, which influenced our methodology and results. Results: A total of 40 psychiatrists participated in the study. The results obtained, although not significant, suggested that psychiatrists with an increased time of practice had more knowledge of advance directives. Nevertheless, less than half of the participants had knowledge about this topic. Conclusion: The number of psychiatrists surveyed indicates the need for further studies on the subject. The influence of the COVID-19 pandemic on this study led to findings such as a change in sensitivity when addressing the topic and greater difficulty in contacting professionals.

Desafios na comunicação de más notícias em unidade de terapia intensiva pediátrica / Challenges in breaking bad news in a pediatric intensive care unit / Desafíos en la comunicación de malas noticias en una unidad de cuidados intensivos pediátrica

Resumo Comunicar más notícias é tarefa desafiadora na prática médica, motivo pelo qual o tema tem adquirido relevância na formação de futuros profissionais. Nas unidades de terapia intensiva, esse tipo de comunicação se mescla a múltiplas situações, a exemplo do manejo de informações envolvendo o agravamento do estado clínico e a possibilidade de morte iminente, especialmente em casos pediátricos. Diante desse contexto, o objetivo desta pesquisa foi compreender os desafios enfrentados por médicos intensivistas na comunicação de más notícias, tendo como eixo de análise algumas questões problematizadas no campo das discussões bioéticas. Os resultados apontaram a necessidade de preparo técnico e pessoal do médico diante desse importante desafio, haja vista que a participação da criança no processo de tratamento ainda é limitada, realidade que dificulta o compartilhamento das informações e, consequentemente, o exercício da autonomia.
