High linoleic acid levels in red blood cells predict a poor response to neoadjuvant chemotherapy in human epidermal growth factor receptor type 2-positive breast cancer patients.

OBJECTIVE: Polyunsaturated fatty acids are categorized as ω-3 or ⍵-6. Previous studies demonstrate that breast cancers display a high expression of fatty acid synthase and high fatty acid levels. Our study sought to determine if changes in plasma or red blood cell membrane fatty acid levels were associated with the response to preoperative (neoadjuvant) chemotherapy in non-metastatic breast cancer patients. METHODS: Our prospective study assessed fatty acid levels in plasma and red blood cell membrane. Response to neoadjuvant chemotherapy was evaluated by the presence or absence of pathologic complete response and/or residual cancer burden. RESULTS: A total of 28 patients were included. First, patients who achieved pathologic complete response had significantly higher neutrophil-to-lymphocyte ratio versus no pathologic complete response (P = 0.003). Second, total red blood cell membrane polyunsaturated fatty acids were higher in the absence of pathologic complete response (P = 0.0028). Third, total red blood cell membrane ⍵-6 polyunsaturated fatty acids were also higher in no pathologic complete response (P < 0.01). Among ⍵-6 polyunsaturated fatty acids, red blood cell membrane linoleic acid was higher in the absence of pathologic complete response (P < 0.01). Notably, plasma polyunsaturated fatty acid, ⍵-6, and linoleic acid levels did not have significant differences. A multivariate analysis confirmed red blood cell membrane linoleic acid was associated with no pathologic complete response; this was further confirmed by receiver operating characteristic analysis (specificity = 92.3%, sensitivity = 76.9%, and area under the curve = 0.855). CONCLUSIONS: Pending further validation, red blood cell membrane linoleic acid might serve as a predictor biomarker of poorer response to neoadjuvant chemotherapy in non-metastatic human epidermal growth factor receptor type 2-positive breast cancer. Measuring fatty acids in red blood cell membrane could offer a convenient, minimally invasive strategy to identifying patients more likely to respond or those with chemoresistance.

Effect of refining and pressing temperature on chemical attributes of canola oil produced in Chile

The consumption of vegetable oils is common in our daily diet. Rapeseed oil (canola oil) is the third most consumed edible oil in the world, followed by palm and soybean oils in terms of production. Rapeseed oil has a low proportion of saturated fatty acids, while it is rich in unsaturated fatty acids, as well as in healthy compounds such as phenols, tocopherols, phytosterols, carotenoids, and fat-soluble vitamins. However, processing technologies affect the content and functional activities of bioactive compounds in the oil. Aim: To assess any potential effect of hot or cold pressing and a refining process on the nutritional value and the profile of several bioactive compounds in canola oils produced in Chile. Methods: Canola oils were characterized regarding their fatty acid profile, phytosterol and tocopherol composition, total phenol content, and antioxidant activity, according to the mode of extraction (cold or hot pressed) and before and after bWeing subjected to a refining process. Results: Fatty acid profiles were not significantly different in any of the analyzed canola oils. Refining but not temperature extraction led to a sharp decrease of phytosterols and tocopherols. Hot pressing significantly increased the amount of total phenols (3.1 times) and the antioxidant activity measured by ORAC (3.1 times) and DPPH (8.3 times) compared to the cold extraction. However, phenolic concentration and antioxidant capacity decreased after refining. Conclusions: Refining processes should be adjusted to reduce the loss of bioactive compounds in the oil.

El consumo de aceites vegetales es habitual en nuestra dieta diaria. El aceite de colza (aceite de canola) es el tercer aceite comestible más consumido en el mundo, seguido por los aceites de palma y soja en términos de producción. El aceite de colza tiene una baja proporción de ácidos grasos saturados, mientras que es rico en ácidos grasos insaturados, así como en compuestos liposolubles saludables como fenoles, tocoferoles, fitoesteroles, carotenoides y vitaminas. Sin embargo, las tecnologías de procesamiento afectan el contenido y las actividades funcionales de los compuestos bioactivos en el aceite. Objetivo: Evaluar cualquier efecto potencial del prensado en caliente o en frío y un proceso de refinación sobre el valor nutricional y el perfil de varios compuestos bioactivos en los aceites de canola producidos en Chile. Métodos: Los aceites de canola se caracterizaron en cuanto a su perfil de ácidos grasos, composición de fitoesteroles y tocoferoles, contenido de fenoles totales y actividad antioxidante, según el modo de extracción (prensado en frío o en caliente) y antes y después de ser sometidos a un proceso de refinación. Resultados: Los perfiles de ácidos grasos no fueron significativamente diferentes en ninguno de los aceites de canola analizados. La refinación, pero no la extracción en caliente, condujo a una fuerte disminución de los fitoesteroles y tocoferoles. El prensado en caliente aumentó significativamente la cantidad de fenoles totales (3,1 veces) y la actividad antioxidante medida por ORAC (3,1 veces) y DPPH (8,3 veces) en comparación con la extracción en frío. Sin embargo, la concentración de fenoles y la capacidad antioxidante disminuyeron después del refinado. Conclusión: Los procesos de refinación deben ajustarse para reducir la pérdida de compuestos bioactivos en el aceite.

Dietary and Nutritional Interventions in Nonalcoholic Fatty Liver Disease in Pediatrics.

Nonalcoholic fatty liver disease (NAFLD) is pediatrics' most common chronic liver disease. The incidence is high in children and adolescents with obesity, which is associated with an increased risk of disease progression. Currently, there is no effective drug therapy in pediatrics; therefore, lifestyle interventions remain the first line of treatment. This review aims to present an updated compilation of the scientific evidence for treating this pathology, including lifestyle modifications, such as exercise and dietary changes, highlighting specific nutritional strategies. The bibliographic review was carried out in different databases, including studies within the pediatric population where dietary and/or nutritional interventions were used to treat NAFLD. Main interventions include diets low in carbohydrates, free sugars, fructose, and lipids, in addition to healthy eating patterns and possible nutritional interventions with n-3 polyunsaturated fatty acids (EPA and DHA), amino acids (cysteine, L-carnitine), cysteamine, vitamins, and probiotics (one strain or multi-strain). Lifestyle changes remain the main recommendation for children with NAFLD. Nevertheless, more studies are required to elucidate the effectiveness of specific nutrients and bioactive compounds in this population.

High Fatality Rates in Pediatric Multisystem Inflammatory Syndrome: A Multicenter Experience From the Epicenter of Brazil's Coronavirus Pandemic.

BACKGROUND: Brazil´s case fatality rate (CFR) of pediatric multisystem inflammatory syndrome in children and adolescents (MIS-C) is among the highest worldwide. Despite these concerns, limited hospital-based and comprehensive pediatric data have been published on MIS-C in Brazilian children. METHODS: We performed a descriptive analysis of the MIS-C scores in 16 public and private hospitals providing secondary and tertiary care in the metropolitan area of São Paulo, Brazil. Clinical and demographic information were systematically extracted from the electronic medical records of each patient. Logistic regression analysis was performed to identify the combined effects of MIS-C phenotype, disease severity and comorbidity as dependent variables. RESULTS: A total of 101 patients met the MIS-C criteria and were evaluated. The median age was 67 months, 60% were male, 28.7% were black or afrodescendant and 62.3% were admitted to public hospitals. Underlying medical conditions were observed in 16.8% of patients and were associated with a longer duration of hospitalization. A Kawasaki disease-like phenotype was observed in 43.5% of patients, and they demonstrated a trend of lower median age. Children with severe MIS-C were older (median age 91 months vs. 36 months) and had a nonspecific phenotype, more cardiovascular and respiratory involvement and kidney injury; 73.3% required intensive care, 20.8% required mechanical ventilation and 35.6% required inotropic support. Four deaths occurred (CFR = 3.9%), three of which were in healthy participants. CONCLUSION: We identified a lower median age, particularly among children with Kawasaki disease-like phenotypes, those with a significant need for intensive care, and a high CFR in MIS-C. Our findings confirmed the increased severity of the disease in the selected Brazilian population.

International Pediatric COVID-19 Severity Over the Course of the Pandemic.

Importance: Multiple SARS-CoV-2 variants have emerged over the COVID-19 pandemic. The implications for COVID-19 severity in children worldwide are unclear. Objective: To determine whether the dominant circulating SARS-CoV-2 variants of concern (VOCs) were associated with differences in COVID-19 severity among hospitalized children. Design, Setting, and Participants: Clinical data from hospitalized children and adolescents (younger than 18 years) who were SARS-CoV-2 positive were obtained from 9 countries (Australia, Brazil, Italy, Portugal, South Africa, Switzerland, Thailand, UK, and the US) during 3 different time frames. Time frames 1 (T1), 2 (T2), and 3 (T3) were defined to represent periods of dominance by the ancestral virus, pre-Omicron VOCs, and Omicron, respectively. Age groups for analysis were younger than 6 months, 6 months to younger than 5 years, and 5 to younger than 18 years. Children with an incidental positive test result for SARS-CoV-2 were excluded. Exposures: SARS-CoV-2 hospitalization during the stipulated time frame. Main Outcomes and Measures: The severity of disease was assessed by admission to intensive care unit (ICU), the need for ventilatory support, or oxygen therapy. Results: Among 31 785 hospitalized children and adolescents, the median age was 4 (IQR 1-12) years and 16 639 were male (52.3%). In children younger than 5 years, across successive SARS-CoV-2 waves, there was a reduction in ICU admission (T3 vs T1: risk ratio [RR], 0.56; 95% CI, 0.42-0.75 [younger than 6 months]; RR, 0.61, 95% CI; 0.47-0.79 [6 months to younger than 5 years]), but not ventilatory support or oxygen therapy. In contrast, ICU admission (T3 vs T1: RR, 0.39, 95% CI, 0.32-0.48), ventilatory support (T3 vs T1: RR, 0.37; 95% CI, 0.27-0.51), and oxygen therapy (T3 vs T1: RR, 0.47; 95% CI, 0.32-0.70) decreased across SARS-CoV-2 waves in children 5 years to younger than 18 years old. The results were consistent when data were restricted to unvaccinated children. Conclusions and Relevance: This study provides valuable insights into the impact of SARS-CoV-2 VOCs on the severity of COVID-19 in hospitalized children across different age groups and countries, suggesting that while ICU admissions decreased across the pandemic in all age groups, ventilatory and oxygen support generally did not decrease over time in children aged younger than 5 years. These findings highlight the importance of considering different pediatric age groups when assessing disease severity in COVID-19.

Effect of a pescetarian and vegan diet on fatty acid composition in blood and spermatozoa in young healthy men.

INTRODUCTION: There is a growing interest in vegetarian and vegan diets, but both can potentially affect tissue fatty acids (FA) composition. We aimed to evaluate the effect of vegetarian diets on plasma, erythrocytes, and sperm n-3 polyunsaturated fatty acids (n-3 PUFA) status in healthy young men. METHODS: Four groups were studied: i) men consuming a regular omnivore diet (OMV-1, n = 35); ii) men consuming an omnivore diet but excluding fish and seafood (OMV-2, n = 34); iii) men consuming a pescetarian diet (including dairy, eggs, fish, and seafood) (PESC, n = 36); and iv) men following a strict vegan diet (VEG, n = 35). Participants in each group should follow their diet for at least the previous 12 months. Diet evaluation used a structured validated food frequency questionnaire. FA composition was measured in plasma, erythrocyte phospho-lipids, and spermatozoa by gas-liquid chromatography, expressed as a mole percentage of the total FA content. RESULTS: Main findings showed higher alpha-linolenic fatty acid (ALA) and total n-3 PUFA dietary intake in the VEG group. In plasma, arachidonic and eicosapentaenoic acids were higher in OMV and PESC groups, whereas docosahexaenoic acid (DHA) level was lower in VEG. Higher ALA, but reduced DHA and total n-3 PUFA levels were found in erythrocytes and spermatozoa in the VEG group. CONCLUSION: Higher dietary ALA intake was found in pescetarians and vegan men. However, the higher ALA intake was not reflected in higher DHA content in the evaluated tissues. PUFA assessment, with particular emphasis in DHA, are necessary to improve PUFA status in vegan men.

Potential Clinical Applications of Pro-Resolving Lipids Mediators from Docosahexaenoic Acid.

Docosahexaenoic acid (C22:6n-3, DHA) is the precursor of specialized pro-resolving lipid mediators (SPMs), such as resolvin, protectin, and maresin families which have been considered therapeutic bioactive compounds for human health. Growing evidence indicates that DHA and SPMs are beneficial strategies in the amelioration, regulation, and duration of inflammatory processes through different biological actions. The present review discusses the reported therapeutic benefits of SPMs on various diseases and their potential clinical applications.

Cardiac Hydatid Cyst: An Uncommon Cause of Complete Atrioventricular Block. / Cisto Hidático Cardíaco: Uma Causa Incomum de Bloqueio Atrioventricular Total.

Hydatidosis is a zoonosis caused by Echinococcus granulosus, leading to the formation of cysts on involved organs. Cardiac involvement is rare and can cause a wide range of complications secondary to rupture, embolization, or compression. Its diagnosis is challenging, and is generally confirmed through data related to clinical manifestations, environmental exposure, and laboratory and imaging exams. Surgical removal is necessary in most cases, in which an association with antiparasite therapy is recommended. The present article describes a case of a cardiac hydatid cyst associated with a complete atrioventricular block (AVB) in a young adult patient, with the need for a pacemaker implant, an atypical presentation, and scarce reports in the literature.

Characteristics and clinical outcomes of COVID-19 in children: a hospital-based surveillance study in Latin America's hardest-hit city.

Background: In 2020, Brazil became the epicentre of the coronavirus disease (COVID-19) pandemic in Latin America, resulting in an unparalleled health catastrophe. Nevertheless, comprehensive clinical reports in Brazilian children are not available. Methods: This retrospective, hospital-based, active surveillance study was performed to identify paediatric patients with COVID-19 who presented at a private academic medical centre in a large urban area between March 2020 and March 2021. Clinical and demographic information was analysed for those requiring hospitalization, those with severe illness and those with clinical syndromes. Results: In total, 964 symptomatic cases were evaluated; of these, 17.7% required hospitalization, and 27.5% of hospitalized cases were classified as severe/critical. Acute bronchiolitis and pneumonia were the most common causes of hospitalization among the severe cases. Twenty-seven hospitalized children fulfilled the diagnostic criteria for multi-system inflammatory syndrome (median age 29 months; 85.2% cases were non-severe). A significant co-existing condition was present in 29% of hospitalized children. The risk of hospitalization was higher in children with at least one comorbidity, children aged <2 years and obese children. Increased risk of severe disease was described among those with leukopenia, leukocytosis or any significant comorbidity. No deaths occurred among the study population. Conclusion: Although most children with COVID-19 experienced mild disease, and no deaths occurred among the study population, a significant proportion of cases required hospitalization and developed severe illness. Obesity, young age, underlying comorbidity, leukopenia and leukocytosis were risk factors for hospitalization or severe disease.

Sofrimento e solidão: narrativas de profissionais do setor de oncologia / Sufrimiento y soledad: narrativas de profesionales del sector oncológico / Suffering and loneliness: narratives of professionals from oncology's sector

RESUMO. No setor de oncologia das instituições hospitalares, visando o cuidado humanizado, tem sido desejável a atuação de profissionais de diferentes áreas. Esse estudo teve o objetivo de investigar a experiência subjetiva dos diferentes profissionais que atuam nesse setor. A pesquisa contou com a participação de 23 profissionais da área de oncologia de um hospital público situado no interior do Rio Grande do Sul. Nesse estudo qualitativo, os participantes foram entrevistados individualmente, sendo tais entrevistas mediadas pela apresentação de uma narrativa interativa, a qual eles eram convidados a inventarem um desfecho e a associarem livremente. Foram identificadas, após consideração psicanalítica, duas categorias intituladas 'Aos outros eu devolvo a dor' e 'Dança da solidão'. A partir delas foi possível identificar, respectivamente, como os profissionais experienciam, em seu cotidiano de trabalho, suas relações com os pacientes e com os seus colegas de equipe. Observou-se que, para os participantes, o cotidiano de trabalho é atravessado por sofrimento por terem de lidar com o mal-estar de seus pacientes, bem como as perdas frequentes, sofrimento esse que fica acentuado por não terem condições de compartilhá-lo com os seus pares no trabalho. Conclui-se que se faz necessário o desenvolvimento de ações, em especial a constituição de um enquadre clínico em que os profissionais possam ter trocas afetivas entre si, o que poderia, num só tempo, tanto ajudá-los a lidar com o sofrimento despertado no setor de oncologia quanto ajudá-los a se sentirem pertencentes a essa equipe composta por diferentes áreas de especialidade.

RESUMEN. En el sector de Oncología de las instituciones hospitalarias, con miras a la atención humanizada, ha sido deseable la actuación de profesionales de diferentes áreas. Este estudio tuvo como objetivo investigar la experiencia subjetiva de los diferentes profesionales que laboran en este sector. La investigación contó con la participación de 23 profesionales del área de Oncología de un hospital público ubicado en el interior de Rio Grande do Sul. En este estudio cualitativo, los participantes fueron entrevistados individualmente, siendo dichas entrevistas mediadas por la presentación de una narrativa interactiva, a la que fueron invitados a inventar un desenlace y asociarse libremente. Se identificaron dos categorías, después de una consideración psicoanalítica, tituladas 'Devuelvo el dolor a los demás' y 'Danza de la soledad'. A partir de ellos, fue posible identificar, respectivamente, cómo los profesionales viven, en su trabajo diario, sus relaciones con los pacientes y con sus compañeros de equipo. Se observó que, para los participantes, el trabajo diario está atravesado por el sufrimiento porque tienen que convivir con el malestar de sus pacientes, así como con las frecuentes pérdidas, sufrimiento que se acentúa al no poder compartirlo con los demás compañeros de trabajo. Se concluye que es necesario desarrollar acciones, especialmente la constitución de un entorno clínico en el que los profesionales puedan tener intercambios afectivos entre sí, que puedan, en un solo tiempo, ayudarles a afrontar el sufrimiento suscitado en el sector de Oncología, además de ayudarles a sentirse parte de este equipo formado por diferentes áreas de especialidad.

ABSTRACT. In the Oncology Ward of hospital institutions, aiming humanized care, the performance of professionals from different areas has been desirable. This study aimed to investigate the subjective experience of the different professionals who work in this sector. The research was developed with the participation of 23 professionals from the Oncology area of ​​a public hospital located in Rio Grande do Sul. In this qualitative study, they were interviewed individually. Those interviews were mediated by the presentation of an interactive narrative, with the participants being asked to create an outcome and to freely associate. Two categories were identified, after psychoanalytic consideration, entitled 'I return the pain to others' and 'Dance of solitude'. From those categories, it was possible to identify, respectively, how professionals experience, in their daily work, their relations with patients and with their teammates. It was observed that, for the participants, the daily work is crossed by suffering because they have to deal with the discomfort of their patients, as well as the frequent losses, a suffering that is accentuated by not being able to share it with their peers at work. It is concluded that it is necessary to develop actions, especially the constitution of a clinical setting in which professionals can have affective exchanges with each other, which could, in just one time, help them to deal with the suffering aroused in the Oncology sector as well as help them to feel that they belong to this team made up of different areas of specialty.

ABSTRACT Chia (Salvia hispanica L.) is a seed native to the southern part of Mexico and Guatemala, which has spread to other Latin American countries. This seed has been used for different purposes throughout history, where it stands out as a food product due to its great versatility, since it can be used as a seed, whole meal flour, fiber and/or protein fractions and oil. Currently, the investigation of new food sources that provide health benefits has managed to collect information on the chemical composition and nutritional value of this seed and its derivatives (flour and oil). For polyunsaturated fatty acid content, n-3 is found, highlighting alpha linolenic acid (C18:3n-3, ALA), which is proposed as an alternative source of this nutrient to foods of other origins. In addition, the fiber content of chia, is mainly insoluble fiber. Regarding the benefits associated with chia consumption, it is closely related to chronic non-communicable diseases such as dyslipidemia, diabetes, type II, hypertension, cancer, among others, managing to attract the attention of researchers to control and prevent these pathologies that are increasing in world population. Therefore, it is relevant to deepen the knowledge available about this seed and its by-products in order to establish the possible molecular mechanisms that are involved in generating health benefits. The objective of this review is to present an update on the benefits associated with consumption of chia seed and its derivatives.

Albahaca: Composición química y sus beneficios en salud

Las plantas medicinales se han utilizado tradicionalmente en la medicina popular debido a sus reconocidos efectos curativos naturales. Se estima que alrededor de dos tercios de la población mundial utilizan la medicina tradicional para sus necesidades médicas primarias. La albahaca (Ocimum basilicum L.) es uno de los principales cultivos herbáceos del mundo que ha mostrado componentes que pueden ser beneficiosos para el tratamiento de enfermedades cardiovasculares, trastornos inflamatorios y disminución del riesgo de cáncer. Este artículo presenta una revisión acerca de la planta y semillas de albahaca desde el 2010 a la fecha, con el objetivo de identificar la composición química (macronutrientes-proteínas, lípidos, carbohidratos; compuestos volátiles y polifenoles) y sus beneficios para la salud en función de la evidencia en humanos, modelo in vivo e in vitro. La literatura reciente muestra que las hojas y semillas de albahaca son una buena fuente de ácidos grasos α-linolénico, aceite y polifenoles con propiedades antioxidantes y antiinflamatorias que afectaría de forma favorable en la salud, restaurando la homeostasis en diversas patologías. Sin embargo, hasta la fecha, no se han dilucidado por completo los mecanismos moleculares involucrados.

Medicinal plants have traditionally been used in folk medicine for their natural healing effects. It is estimated that around two-thirds of the world's population uses traditional medicine for their primary medical needs. Basil (Ocimum basilicum) is one of the main herbal crops in the world that has shown components that can be beneficial for the treatment of cardiovascular diseases, inflammatory disorders, and decreased risk of cancer. This article presents a review of the state of the art about the basil plant and seeds from 2010 to date, with the aim of identifying the chemical composition (macronutrients-proteins, lipids, carbohydrates; volatile compounds and polyphenols) and its benefits on health based on evidence in humans, in vivo and in vitro models. Recent literature shows that basil leaves and seeds are a good source of α-linolenic fatty acids, essential oils and polyphenols with antioxidant and anti-inflammatory properties that would have a favorable impact on health, restoring homeostasis in various pathologies. However, to date, the molecular mechanisms involved have not been fully elucidated.

A pandemia de Covid-19 narrada por mulheres: o que dizem as profissionais de saúde? / The Covid-19 pandemic told by women: what do health professionals say?

RESUMO Este artigo objetivou investigar narrativas de mulheres brasileiras que trabalham como profissionais de saúde no contexto da pandemia de Covid-19. Parte de uma pesquisa que discute as repercussões subjetivas desse contexto, a partir da perspectiva de gênero, para a qual foi construído um questionário on-line, que convida as mulheres a narrar suas vivências. A investigação foi desenvolvida no âmbito da psicologia, articulando os métodos psicanalítico e fenomenológico, aliados às teorias feministas, em prol de uma análise crítica e situada de fenômenos contemporâneos. A análise qualitativa dos relatos de 602 mulheres levou a diferentes aspectos, dentre os quais se destaca a intensificação das exigências de cuidado, seja no âmbito familiar, seja no âmbito profissional, o que as leva a desconsiderar o autocuidado. Ao mesmo tempo, a exposição ao risco e o medo constante parecem levar à ocorrência de um contágio psíquico a partir do contato com os pacientes acometidos pela Covid-19, o que produz sofrimento intenso. Os resultados evidenciam como as questões de gênero repercutem nas mulheres que trabalham na área da saúde, reafirmando a necessidade de considerar as especificidades desse público na elaboração de políticas públicas e dispositivos de atenção em saúde mental.

ABSTRACT The article aims to investigate narratives of Brazilian women working as healthcare professionals in the context of the Covid-19 pandemic. It is part of a research that discusses the subjective repercussions of this context, from a gender perspective, for which an online questionnaire was constructed, inviting women to narrate their experiences. The research was developed within the scope of psychology, articulating psychoanalytic and phenomenological methods, allied to feminist theories, in favor of a critical and situated analysis of contemporary phenomena. The qualitative analysis of the reports of 602 women led to different aspects, among which we highlight the intensification of care demands, whether in the family or the professional sphere, which leads them to disregard self-care. At the same time, the exposure to risk and the constant fear seems to lead to the occurrence of a psychic contamination from the contact with patients affected by Covid-19, which produces intense suffering. The results show how gender issues impact women working in the health field, reaffirming the need to consider the specificities of this public in the development of public policies and mental health care devices.

Silver nanoparticles (AgNPs) internalization and passage through the Lactuca sativa (Asteraceae) outer cell wall.

Silver nanoparticle (AgNPs) toxicity is related to nanoparticle interaction with the cell wall of microorganisms and plants. This interaction alters cell wall conformation with increased reactive oxygen species (ROS) in the cell. With the increase of ROS in the cell, the dissolution of zero silver (Ag0) to ionic silver (Ag+) occurs, which is a strong oxidant agent to the cellular wall. AgNP interaction was evaluated by transmission electron microscopy (TEM) on Lactuca sativa roots, and the mechanism of passage through the outer cell wall (OCW) was also proposed. The results suggest that Ag+ binds to the hydroxyls (OH) present in the cellulose structure, thus causing the breakdown of the hydrogen bonds. Changes in cell wall structure facilitate the passage of AgNPs, reaching the plasma membrane. According to the literature, silver nanoparticles with an average diameter of 15nm are transported across the membrane into the cells by caveolines. This work describes the interaction between AgNPs and the cell wall and proposes a transport model through the outer cell wall.

Application of thermography in the diagnostic investigation of thyroid nodules.

Thyroid nodules (TN) are common in the general population, and the clinical importance of diagnosing thyroid nodules is based on excluding the possibility of thyroid cancer, which occurs in 7-15% of cases. The thyroid gland, owing to its superficial location, is easily accessible via thermography, a noninvasive method of recording body temperature that measures infrared radiation emitted by the body surface. Therefore, this study aimed to evaluate the temperature differences between benign and malignant TN by using thermography. We conducted a cross-sectional study where 147 TN were divided into two groups: the first group included 120 benign nodules and the other included 27 malignant nodules. All the nodules were subjected to ultrasound, fine needle aspiration biopsy, and thermography. On analyzing the thermography results, the benign nodules had a higher temperature at the beginning of the thermography evaluation, and the malignant nodules showed a higher temperature in the middle and at the end (Ft). Using the relationships, it was observed that the temperature delta (ΔT), ΔT nodule/ΔT healthy, ΔT nodule minus ΔT healthy, and nodule Ft minus Ft of the healthy region were higher in malignant nodules. The ROC curve analysis of ΔT demonstrated a cutoff point of 2.38°C, with a sensitivity of 0.963 and specificity of 0.992. Malignant nodules have higher temperatures than benign nodules on thermographic evaluation. This finding suggests that thermography can be a useful tool in the diagnosis of thyroid nodules.

Glycated Hemoglobin and Blood Pressure Levels in Adults With Type 2 Diabetes: How Many Patients Are on Target?

OBJECTIVES: Achieving glycated hemoglobin (A1C) and blood pressure targets is an important strategy for preventing chronic vascular complications in diabetes. Our aim in this study was to determine the proportion of type 2 diabetes patients who meet the recommended A1C and arterial blood pressure targets and to identify the determinants of failure to do so. METHODS: A cross-sectional study was conducted in an outpatient endocrine clinic at a university hospital. The A1C goal was 7% in general and 8% for patients with advanced chronic complications. Regarding blood pressure, the overall expected target was 140/90 mmHg. RESULTS: A total of 602 type 2 diabetes patients were analyzed: 62% were female, 14% self-reported as black, mean age was 63±11 years, mean diabetes duration was 17±9 years and median A1C was 8.0% (interquartile range, 7.0% to 9.5%). Macrovascular disease was present in 33% of the patients, diabetic retinopathy in 47%, peripheral neuropathy in 43% and diabetic kidney disease in 56%. Regarding metabolic control, 403 (67%) patients were not at the adjusted target A1C level, and being female, black, young and an insulin user were the main determinants of poor glycemic control. Regarding blood pressure, 348 (58%) patients were not at the recommended targets, and a more advanced age was the main associated factor. CONCLUSIONS: Because more than half of type 2 diabetes outpatients do not meet the recommended A1C and blood pressure target values, there is a major call to overcome the therapeutic inertia and target treatment of patients on an individual basis.

O luto de pais: considerações sobre a perda de um filho criança / Parents' grief: thoughts on the loss of a child / El duelo de los padres: consideraciones Sobre la pérdida de un hijo todavía niño

A morte fora de lugar, a perda dos projetos futuros, das idealizações depositadas no filho e o lugar insubstituível que ele ocupa no imaginário dos pais dificultam o processo de elaboração do luto. Neste trabalho, buscou-se compreender como os pais vivenciam a perda de um filho ainda criança e discutir aspectos característicos desses casos. Foi realizada uma pesquisa qualitativa, em que se entrevistou 11 pais que perderam os filhos crianças, cujas mortes ocorreram em um intervalo que varia entre quatro meses e um ano e quatro meses em relação à entrevista. As entrevistas foram semiestruturadas com eixos norteadores que direcionaram os temas a serem abordados, e os dados foram trabalhados por meio da análise temática, revelando os núcleos de sentido da comunicação. Entre os principais elementos constituintes das narrativas, destacam-se: a dor incomparável, culpa, as experiências diferentes entre pais e mães, os outros filhos, o sentimento de perda de uma parte de si, a perda do objeto narcísico e a vivência do luto diante do funcionamento social contemporâneo. O estudo demonstrou a importância de considerar a singularidade do luto parental e não o confundir com a melancolia. Esses aspectos precisam ser reconhecidos, junto às diferenças que marcam as experiências distintas entre pai e mãe, o narcisismo dos pais e o contexto contemporâneo, a fim de auxiliar na construção de intervenções adequadas nesses casos. Sublinha-se a importância da fala na organização de uma narrativa que permita a construção de um sentido para a perda e a elaboração do luto. (AU)

The sudden death; the interruption of future projects, of the idealizations set upon a child; and its irreplaceable role within parents' imagination hamper the grief resolution process due to the loss of a child. Thus, this study aimed to understand how parents experience the loss of a child, discussing particular aspects related to this situation. Through a qualitative approach, semi-structured interviews guided by thematic axes were conducted with 11 parents who had lost their children between four months and one year and four months before the interview. Collected data underwent thematic analysis, revealing the communication cores. Incomparable pain, guilt, different experiences between fathers and mothers, other children, the feeling of losing a part of themselves, the loss of a narcissistic object, and the experience of grief towards the contemporary social functioning were the main elements present in parents' narratives. This study demonstrates the importance of considering the singularity of the parental grief without misinterpreting it as melancholy. To help developing appropriate interventions aimed at these cases, one must recognize the aforementioned aspects, as well as the differences marking paternal and maternal experiences, parents' narcissism, and the contemporary context. The findings also point to the relevance of speech in organizing a narrative that enables the construction of a meaning for the loss and grief resolution.(AU)
