RESUMO

Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.


Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.


Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas. Isso aumenta o risco de complicações relacionadas ao seu uso, portanto, podem ser evitáveis. O objetivo deste estudo é conhecer as características do uso do cateterismo urinário em pacientes internados em enfermarias de cuidados moderados de um hospital universitário terciário, determinar a frequência, duração e indicações mais frequentes, bem como avaliar a presença de complicações associadas ao mesmo. Metodologia: Estudo transversal, realizado em quartos de cuidados moderados de um hospital terciário e universitário em Montevidéu, Uruguai, em 21 de dezembro de 2022. Foram incluídos pacientes que apresentaram ou apresentaram sonda vesical durante a internação atual e a coleta de variáveis ​​foi concluída .revisando o histórico médico. Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.

RESUMO

Introducción: La caries es una de las enfermedades crónicas que más afecta a la humanidad, los niños son un grupo de alto riesgo de presentarla. La Calidad de Vida Relacionada con Salud Oral (CVRSO) se refiere a la percepción de las condiciones bucales de uno mismo y la manera en que los factores afectados impactan el bienestar y desempeño en las actividades diarias, el desarrollo de indicadores de esta se ve limitado por el nivel cognitivo de los niños, lo que genera el P-CPQ para determinar la percepción parental. Objetivo: determinar la percepción parental de la calidad de vida relacionada con la salud bucal de los niños de 6 a 10 años. Materiales y Métodos: se realizó un estudio observacional descriptivo con componente analítico. Se llevó a cabo una encuesta a 98 padres, el P-CPQ modificado que consta de 23 preguntas que abarcan las subescalas de síntomas orales, limitaciones funcionales, bienestar emocional y bienestar social. Resultados: Relacionando los resultados del cuestionario con la presencia de caries en dientes permanentes se reportó el aumento de caries con la edad; el sexo femenino predominó entre los participantes con caries siendo el 63,8%. La puntuación media fue de 13,6 (DE=13,1). Se presentó una asociación estadísticamente significativa entre la percepción parental de CVRSO de los niños y la presencia de caries dental en dientes permanentes (p=0,004). Conclusiones: Se concluyó que la presencia de caries en dientes permanentes en niños de 6 a 10 años puede disminuir significativamente la CVRSO en las dimensiones de síntomas orales, limitaciones funcionales y bienestar social.


Introduction: Caries is one of the chronic diseases that most affects humanity; children are a high-risk group for developing it. Oral Health Related Quality of Life (OHRQL) refers to the perception of one's own oral conditions and the way in which the affected factors impact well-being and performance in daily activities. The development of indicators of this is limited by the cognitive level of the children, which led to the P-CPQ to determine parental perception. Objective: to determine the parental perception of the quality of life related to the oral health of children from 6 to 10 years old. Materials and Methods: This was a descriptive and observational study with an analytical component. A survey of 98 parents was conducted, using the modified P-CPQ which consists of 23 questions covering the subscales of oral symptoms, functional limitations, emotional well-being, and social well-being. Results: Relating the results of the questionnaire with the presence of cavities in permanent teeth, an increase in cavities with age was reported; the female sex predominated among the participants with cavities, being 63.8%. The mean score was 13.6 (SD=13.1). There was a statistically significant association between parental perception of children's OHRQL and the presence of dental caries in permanent teeth (p=0.004). Conclusions: The presence of caries in permanent teeth in children aged 6 to 10 years can significantly reduce OHRQLin the dimensions of oral symptoms, functional limitations and social well-being.

RESUMO

En la actualidad, diversos estudios han explorado las diferencias de las conductas de salud en los estudiantes universitarios de acuerdo con características como edad, sexo y ciclo de estudio, no obstante, estos se han centrado en un enfoque frecuentista basado en la prueba de significancia de la hipótesis nula (NHST). Objetivo. Explorar las diferencias de las conductas de salud de acuerdo con el sexo, edad y ciclo académico, así como establecer la relación entre estas y la percepción de salud general en estudiantes universitarios peruanos, desde un enfoque bayesiano. Materiales y métodos. Se ejecutó un estudio cuantitativo, comparativo, correlacional y transversal, en una muestra de 708 universitarios seleccionados de manera intencional. Se utilizó el cuestionario de conductas de salud (CEJUV-R) y una ficha de datos sociodemográficos. Resultados. Los hallazgos muestran que los hombres tienen mejores hábitos de actividad y condición física y organización del sueño, con respecto a las mujeres. Asimismo, se observa una evidencia moderada a favor de la hipótesis alternativa del autocuidado en función de la edad y el ciclo académico. Finalmente, la actividad física, la organización del descanso, el autocuidado y la organización del sueño presentan evidencias muy fuertes (BF>100) de su relación con la percepción general de salud. Conclusión. El análisis bayesiano mostró evidencia a favor de la hipótesis alterna en algunas de las conductas de salud en función del sexo, edad y ciclo académico, lo que resaltan la importancia de promover conductas más saludables entre los estudiantes universitarios peruanos atendiendo a sus características personales.


Currently, several studies have explored the differences in health behaviors in university students according to characteristics such as age, sex and study cycle; however, these have focused on a frequentist approach based on the null hypothesis significance test (NHST). Objective. To explore the differences in health behaviors according to sex, age and academic cycle, as well as to establish the relationship between these and the perception of general health in Peruvian university students, from a Bayesian approach. Materials and methods. A quantitative, comparative, correlational and cross-sectional study was carried out in a sample of 708 intentionally selected university students. The health behaviors questionnaire (CEJUV-R) and a sociodemographic data sheet were used. Results. The findings show that men have better habits of activity and physical condition and sleep organization, with respect to women. Likewise, there is moderate evidence in favor of the alternative hypothesis of self-care as a function of age and academic cycle. Finally, physical activity, rest organization, self-care and sleep organization present very strong evidence (BF>100) of their relationship with the general perception of health. Conclusion. The Bayesian analysis showed evidence in favor of the alternative hypothesis in some of the health behaviors as a function of sex, age and academic cycle, which highlights the importance of promoting healthier behaviors among Peruvian university students according to their personal characteristics.

RESUMO

Objetivos: Descrever as principais manifestações bucais associadas ao uso das drogas lícitas e ilícitas mais utilizadas atualmente, bem como os cuidados que devem ser tomados durante o atendimento odontológico desses pacientes. Revisão de literatura: Na revisão foi abordada a classificação das substâncias químicas, as principais manifestações orais e os cuidados que o cirurgião-dentista deve ter durante o atendimento odontológico. As substâncias descritas foram álcool, tabaco, benzodiazepínicos, maconha, anfetaminas e cocaína/crack. As complicações de saúde bucal associadas ao abuso de drogas podem resultar da exposição direta dos tecidos orais às drogas durante o fumo ou ingestão, da interação biológica das drogas com a fisiologia normal da cavidade oral e dos efeitos das drogas na função cerebral que resultam em um espectro de comportamentos de dependência, como comportamento de risco, falta de higiene e descuido. Considerações finais: O consumo de substâncias psicoativas, seja a curto ou longo prazo, pode desencadear consequências, tanto na saúde geral como na saúde bucal do usuário. Sob essa perspectiva, o cirurgião-dentista deve estar ciente das manifestações orais e sistêmicas causadas pelas substâncias psicoativas e estar capacitado para diagnosticar, tratar ou também encaminhar o usuário, se necessário, visando um cuidado integral e multiprofissional.


Objective: to describe the main oral manifestations associated with the use of the most commonly used licit and illicit drugs today, as well as the care that should be taken during the dental care of these patients. Literature review: The review covered the classification of chemical substances, the main oral manifestations and the care that dentist should take during dental care. The substances described were alcohol, tobacco, benzodiazepines, marijuana, amphetamines and cocaine/crack. Oral health complications associated with drug abuse can result from direct exposure of oral tissues to drugs during smoking or ingestion, from the biological interaction of drugs with the normal physiology of the oral cavity, and from the effects of drugs on brain function that result in a spectrum of addictive behaviors, such as risk behavior, poor hygiene and carelessness. Final considerations: The consumption of psychoactive substances, whether in the short or long term, can have consequences for both the general health and the oral health of the user. From this perspective, the dentist must be aware of the oral and systemic manifestations caused by psychoactive substances and be able to diagnose, treat or also refer the user, if necessary, aiming for comprehensive, multi-professional care.

RESUMO

SUMMARY: This paper's aim is a morphometric evaluation of liver and portal vein morphometry using ultrasonography in healthy Turkish population. This study was carried out with 189 subjects (107 females, 82 males). The demographic data and the body surface area were calculated. The longitudinal axis of the liver for two lobes, diagonal axis or liver span, anteroposterior diameter of the liver and portal vein, portal vein transverse diameter, caudate lobe anteroposterior diameter, and portal vein internal diameters as well as longitudinal liver scans in an aortic plane, sagittal plane, transverse plane, and kidney axis were measured. All measurements were analyzed according to age, sex, body mass index, obesity and alcohol consumption. The mean values of the age, height, weight and body mass index were calculated as 44.39 years, 167.05 cm, 74.23 kg, and 27.06kg/m2 in females, respectively. The same values were 44.13 years, 167.70 cm, 75.93 kg and 26.71 kg/m2 in males, respectively. There was significant difference between demographic characteristics, gender, and alcohol consumption in terms of anteroposterior diameter of the liver, portal vein transverse diameter of the right side and liver transverse scan. Also, some measurements including portal vein transverse diameter, liver transverse scan and at kidney axis longitudinal scan of liver showed significant difference between the age groups. There was significant difference in diagonal axis and anteroposterior diameter of liver, portal vein internal diameter, and longitudinal liver scans of the aortic plane parameters between obesity situation. The findings obtained will provide important and useful reference values as it may determine some abnormalities related liver diseases. Also, age, sex, obesity and body mass index values can be effective in the liver and portal vein morphometry related parameters.


El objetivo de este artículo fue realizar una evaluación de la morfometría del hígado y la vena porta mediante ecografía en una población turca sana. Este estudio se llevó a cabo en 189 sujetos (107 mujeres, 82 hombres). Se calcularon los datos demográficos y la superficie corporal. Se midió eleje longitudinal del de dos lóbulos del hígado, el eje diagonal o la extensión del hígado, los diámetros anteroposterior del hígado y de la vena porta, el diámetro transversal de la vena porta, anteroposterior del lóbulo caudado y los diámetros internos de la vena porta, así como las exploraciones longitudinales del hígado en un plano aórtico. Se midieron el plano sagital, el plano transversal y el eje del riñón. Todas las mediciones se analizaron según edad, sexo, índice de masa corporal, obesidad y consumo de alcohol. Los valores medios de edad, talla, peso e índice de masa corporal se calcularon como 44,39 años, 167,05 cm, 74,23 kg y 27,06 kg/m2 en las mujeres, respectivamente. Las mismas variable fueron 44,13 años, 167,70 cm, 75,93 kg y 26,71 kg/m2. Hubo diferencias significativas entre las características demográficas, el sexo y el consumo de alcohol en términos de diámetro anteroposterior del hígado, diámetro transversal de la vena porta del lado derecho y exploración transversal del hígado. Además, algunas mediciones, incluido el diámetro transversal de la vena porta, la exploración transversal del hígado y la exploración longitudinal del hígado en el eje del riñón, mostraron diferencias significativas entre los grupos de edad. Hubo diferencias significativas en el eje diagonal y el diámetro anteroposterior del hígado, el diámetro interno de la vena porta y los parámetros de las exploraciones hepáticas longitudinales del plano aórtico entre situaciones de obesidad. Los hallazgos obtenidos proporcionarán valores de referencia importantes y útiles ya que pueden determinar algunas anomalías relacionadas con enfermedades hepáticas. Además, los valores de edad, sexo, obesidad e índice de masa corporal pueden ser eficaces en los parámetros relacionados con la morfometría del hígado y la vena porta.

RESUMO

Abstract Autophagy-related gene (ATG) 5 regulates blood lipids, chronic inflammation, CD4+ T-cell differentiation, and neuronal death and is involved in post-stroke cognitive impairment. This study aimed to explore the correlation of serum ATG5 with CD4+ T cells and cognition impairment in stroke patients. Peripheral blood was collected from 180 stroke patients for serum ATG5 and T helper (Th) 1, Th2, Th17, and regulatory T (Treg) cell detection via enzyme-linked immunosorbent assays and flow cytometry. The Mini-Mental State Examination (MMSE) scale was completed at enrollment, year (Y)1, Y2, and Y3 in stroke patients. Serum ATG5 was also measured in 50 healthy controls (HCs). Serum ATG5 was elevated in stroke patients compared to HCs (P<0.001) and was positively correlated to Th2 cells (P=0.022), Th17 cells (P<0.001), and Th17/Treg ratio (P<0.001) in stroke patients but not correlated with Th1 cells, Th1/Th2 ratio, or Treg cells (all P>0.050). Serum ATG5 (P=0.037), Th1 cells (P=0.022), Th17 cells (P=0.002), and Th17/Treg ratio (P=0.018) were elevated in stroke patients with MMSE score-identified cognition impairment vs those without cognition impairment, whereas Th2 cells, Th1/Th2 ratio, and Treg cells were not different between them (all P>0.050). Importantly, serum ATG5 was negatively linked with MMSE score at enrollment (P=0.004), Y1 (P=0.002), Y2 (P=0.014), and Y3 (P=0.001); moreover, it was positively related to 2-year (P=0.024) and 3-year (P=0.012) MMSE score decline in stroke patients. Serum ATG5 was positively correlated with Th2 and Th17 cells and estimated cognitive function decline in stroke patients.

RESUMO

Introduction: Work-related stress is the physical and emotional manifestation triggered by an imbalance in coping with perceived demands. One of the workers most affected by work-related stress is the nursing staff, a situation that was exacerbated during the COVID-19 pandemic and could affect their quality of life. Objective: To evaluate the connection between quality of life and work-related stress in nurses during the COVID-19 pandemic. Materials and Methods: Analytical, cross-sectional study, with a quantitative approach. Descriptive statistics and multiple linear regression analysis were used for the present study. Results: A negative correlation was obtained between quality of life and stress level (r = -0,438, p < 0,01), and being a professional nurse was related to higher stress levels. On the other hand, being 31 years or older and having more than 12 months of work experience were associated with a higher quality of life score, while being female, single, divorced, or widowed and having higher acute stress scores indicated a significantly worse quality of life. Discussion: Acute stress negatively affects the quality of life of nurses during the COVID-19 pandemic and this differs significantly according to age, sex, marital status, and work experience. Conclusion: It is recommended that the health sector authorities design policies that guarantee strategies to improve the mental health of nursing personnel, as well as to guarantee fair and dignified treatment.

RESUMO

PURPOSE@#The incidence of heatstroke (HS) is not particularly high; however, once it occurs, the consequences are serious. It is reported that calcitonin gene-related peptide (CGRP) is protective against brain injury in HS rats, but detailed molecular mechanisms need to be further investigated. In this study, we further explored whether CGRP inhibited neuronal apoptosis in HS rats via protein kinase A (PKA)/p-cAMP response element-binding protein (p-CREB) pathway.@*METHODS@#We established a HS rat model in a pre-warmed artificial climate chamber with a temperature of (35.5 ± 0.5) °C and a relative humidity of 60% ± 5%. Heatstress was stopped once core body temperature reaches above 41 °C. A total of 25 rats were randomly divided into 5 groups with 5 animals each: control group, HS group, HS+CGRP group, HS+CGRP antagonist (CGRP8-37) group, and HS+CGRP+PKA/p-CREB pathway blocker (H89) group. A bolus injection of CGRP was administered to each rat in HS+CGRP group, CGRP8-37 (antagonist of CGRP) in HS+CGRP8-37 group, and CGRP with H89 in HS+CGRP+H89 group. Electroencephalograms were recorded and the serum concentration of S100B, neuron-specific enolase (NSE), neuron apoptosis, activated caspase-3 and CGRP expression, as well as pathological morphology of brain tissue were detected at 2 h, 6 h, and 24 h after HS in vivo. The expression of PKA, p-CREB, and Bcl-2 in rat neurons were also detected at 2 h after HS in vitro. Exogenous CGRP, CGRP8-37, or H89 were used to determine whether CGRP plays a protective role in brain injury via PKA/p-CREB pathway. The unpaired t-test was used between the 2 samples, and the mean ± SD was used for multiple samples. Double-tailed p < 0.05 was considered statistically significant.@*RESULTS@#Electroencephalogram showed significant alteration of θ (54.50 ± 11.51 vs. 31.30 ± 8.71, F = 6.790, p = 0.005) and α wave (16.60 ± 3.21 vs. 35.40 ± 11.28, F = 4.549, p = 0.020) in HS group compared to the control group 2 h after HS. The results of triphosphate gap terminal labeling (TUNEL) showed that the neuronal apoptosis of HS rats was increased in the cortex (9.67 ± 3.16 vs. 1.80 ± 1.10, F = 11.002, p = 0.001) and hippocampus (15.73 ± 8.92 vs. 2.00 ± 1.00, F = 4.089, p = 0.028), the expression of activated caspase-3 was increased in the cortex (61.76 ± 25.13 vs. 19.57 ± 17.88, F = 5.695, p = 0.009) and hippocampus (58.60 ± 23.30 vs. 17.80 ± 17.62, F = 4.628, p = 0.019); meanwhile the expression of serum NSE (5.77 ± 1.78 vs. 2.35 ± 0.56, F = 5.174, p = 0.013) and S100B (2.86 ± 0.69 vs. 1.35 ± 0.34, F = 10.982, p = 0.001) were increased significantly under HS. Exogenous CGRP decreased the concentrations of NSE and S100B, and activated the expression of caspase-3 (0.41 ± 0.09 vs. 0.23 ± 0.04, F = 32.387, p < 0.001) under HS; while CGRP8-37 increased NSE (3.99 ± 0.47 vs. 2.40 ± 0.50, F = 11.991, p = 0.000) and S100B (2.19 ± 0.43 vs. 1.42 ± 0.30, F = 4.078, p = 0.025), and activated the expression caspase-3 (0.79 ± 0.10 vs. 0.23 ± 0.04, F = 32.387, p < 0.001). For the cell experiment, CGRP increased Bcl-2 (2.01 ± 0.73 vs. 2.15 ± 0.74, F = 8.993, p < 0.001), PKA (0.88 ± 0.08 vs. 0.37 ± 0.14, F = 20.370, p < 0.001), and p-CREB (0.87 ± 0.13 vs. 0.29 ± 0.10, F = 16.759, p < 0.001) levels; while H89, a blocker of the PKA/p-CREB pathway reversed the expression.@*CONCLUSIONS@#CGRP can protect against HS-induced neuron apoptosis via PKA/p-CREB pathway and reduce activation of caspase-3 by regulating Bcl-2. Thus CGRP may be a new target for the treatment of brain injury in HS.

RESUMO

OBJECTIVE@#To investigate the effects and underlying mechanisms of VX765 on osteoarthritis (OA) and chondrocytes inflammation in rats.@*METHODS@#Chondrocytes were isolated from the knee joints of 4-week-old Sprague Dawley (SD) rats. The third-generation cells were subjected to cell counting kit 8 (CCK-8) analysis to assess the impact of various concentrations (0, 1, 5, 10, 20, 50, 100 μmol/L) of VX765 on rat chondrocyte activity. An in vitro lipopolysaccharide (LPS) induced cell inflammation model was employed, dividing cells into control group, LPS group, VX765 concentration 1 group and VX765 concentration 2 group without obvious cytotoxicity. Western blot, real-time fluorescence quantitative PCR, and ELISA were conducted to measure the expression levels of inflammatory factors-transforming growth factor β 1 (TGF-β 1), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α). Additionally, Western blot and immunofluorescence staining were employed to assess the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1). Thirty-two SD rats were randomly assigned to sham surgery group (group A), OA group (group B), OA+VX765 (50 mg/kg) group (group C), and OA+VX765 (100 mg/kg) group (group D), with 8 rats in each group. Group A underwent a sham operation with a medial incision, while groups B to D underwent additional transverse incisions to the medial collateral ligament and anterior cruciate ligament, with removal of the medial meniscus. One week post-surgery, groups C and D were orally administered 50 mg/kg and 100 mg/kg VX765, respectively, while groups A and B received an equivalent volume of saline. Histopathological examination using HE and safranin-fast green staining was performed, and Mankin scoring was utilized for evaluation. Immunohistochemical staining technique was employed to analyze the expressions of matrix metalloproteinase 13 (MMP-13) and collagen type Ⅱ.@*RESULTS@#The CCK-8 assay indicated a significant decrease in cell viability at VX765 concentrations exceeding 10 μmol/L ( P<0.05), so 4 μmol/L and 8 μmol/L VX765 without obvious cytotoxicity were selected for subsequent experiments. Following LPS induction, the expressions of TGF-β 1, IL-6, and TNF-α in cells significantly increased when compared with the control group ( P<0.05). However, intervention with 4 μmol/L and 8 μmol/L VX765 led to a significant decrease in expression compared to the LPS group ( P<0.05). Western blot and immunofluorescence staining demonstrated a significant upregulation of Nrf2 pathway-related molecules Nrf2 and HO-1 protein expressions by VX765 ( P<0.05), indicating Nrf2 pathway activation. Histopathological examination of rat knee joint tissues and immunohistochemical staining revealed that, compared to group B, treatment with VX765 in groups C and D improved joint structural damage in rat OA, alleviated inflammatory reactions, downregulated MMP-13 expression, and increased collagen type Ⅱ expression.@*CONCLUSION@#VX765 can improve rat OA and reduce chondrocyte inflammation, possibly through the activation of the Nrf2 pathway.

RESUMO

ABSTRACT Purpose: The purpose of this study was to investigate the vascular effects of photobiomodulation using a light-emitting diode on the chorioallantoic embryonic membrane of chicken eggs grouped into different times of exposure and to detect the morphological changes induced by the light on the vascular network architecture using quantitative metrics. Methods: We used a phototherapy device with light-emitting diode (670 nm wavelength) as the source of photobiomodulation. We applied the red light at a distance of 2.5 cm to the surface of the chorioallantoic embryonic membrane of chicken eggs in 2, 4, or 8 sessions for 90 s and analyzed the vascular network architecture using AngioTool software (National Cancer Institute, USA). We treated the negative control group with 50 μl phosphate-buffered-saline (pH 7.4) and the positive control group (Beva) with 50 μl bevacizumab solution (Avastin, Produtos Roche Químicos e Farmacêuticos, S.A., Brazil). Results: We found a decrease in total vessel length in the Beva group (24.96% ± 12.85%) and in all the groups that received 670 nm red light therapy (2× group, 34.66% ± 8.66%; 4× group, 42.42% ± 5.26%; 8× group, 38.48% ± 6.96%), compared with the negative control group. The fluence of 5.4 J/cm2 in 4 sessions (4×) showed more regular vessels. The number of junctions in the groups that received a higher incidence of 670 nm red light (4× and 8×) significantly decreased (p<0.0001). Conclusion: Photo-biomodulation helps reduce vascularization in chorioallantoic embryonic membrane of chicken eggs and changes in the network architecture. Our results open the possibility of future clinical studies on using this therapy in patients with retinal diseases with neovascular components, especially age-related macular degeneration.


RESUMO Objetivo: investigar os efeitos vasculares da foto-biomodulação com diodo emissor de luz utilizando membrana embrionária corioalantóide de ovos de galinhas em grupos com diferentes tempos de exposição e detectar as alterações morfológicas por meio de métricas quantitativas promovidas pela luz na arquitetura da rede vascular. Métodos: Um aparelho de fototerapia com diodo emissor de luz no comprimento de onda de 670 nm foi usado como fonte de fotobiomodulação. A luz vermelha foi aplicada a uma distância de 2,5 cm da superfície da membrana embrionária corioalantóide em 2, 4 ou 8 sessões de 90 s a arquitetura da rede vascular foi analisada por meio do software AngioTool (National Cancer Institute, USA). Usamos um grupo controle negativo tratado com 50 µL de solução salina tamponada com fosfato (PBS) pH 7,4 e um grupo controle positivo (Beva) tratado com 50 µL de solução de bevacizumabe (Avastin, Produtos Roche Químicos e Farmacêuticos S.A., Brasil). Resultados: Uma diminuição no comprimento total do vaso foi detectada para o grupo Beva (24,96 ± 12,85%), e para todos os grupos que receberam terapia de luz vermelha de 670 nm, 34,66 ± 8,66% (2x), 42,42 ± 5,26% (4x) e 38,48 ± 6,96% (8x) em comparação ao grupo controle. A incidência de 5,4 J/cm2 em 4 sessões (4x) mostrou vasos mais regulares. A redução foi mais intensa nos grupos que receberam maior incidência de luz vermelha de 670 nm (4x e 8x). Conclusão: A fotobiomodulação contribui para a redução da vascularização nos vasos da membrana embrionária corioalantóide de ovos de galinhas e mudanças na arquitetura da rede. Os achados deste experimento abrem a possibilidade de considerar um estudo clínico usando esta terapia em pacientes com doenças retinais com componentes neovasculares, especialmente degeneração macular relacionada à idade.

RESUMO

ABSTRACT The authors report full-field electroretinogram and optical coherence tomography findings of intravitreal melphalan retinal toxicity. An 18-month-old girl with unilateral group D retinoblastoma was evaluated with light-adapted 3 full-field electroretinogram protocol and optical coherence tomography (I-Stand optical coherence tomography, Optovue) after treatment with intravitreal melphalan for active vitreous seeds. After the third injection, the child developed retinal pigment epithelial changes near the injection site. The photopic response of the full-field electroretinogram standard flash cones showed a decrease in amplitude responses of waves a and b in the affected eye compared to the contralateral eye. Optical coherence tomography showed loss of photoreceptors and outer nuclear layers in the affected eye. Melphalan toxicity is dose-dependent, and despite its treatment benefits, it can affect vision. Our case shows an updated, in-depth retinal toxicity assessment of intravitreal melphalan in the human retina with optical coherence tomography and its correlation with electroretinogram changes.


RESUMO Os autores relatam os achados de eletrorretinograma de campo total e tomografia de coerência óptica (OCT) da toxicidade retiniana ao melfalan intravítreo. Menina de 18 meses com retinoblastoma foi avaliada com fases fotópicas do eletrorretinograma de campo total e tomografia de coerência óptica após o tratamento com melfalan intravítreo. Após a terceira injeção, a criança desenvolveu alterações do epitélio pigmentar da retina próximo ao local da injeção. A resposta fotópica do eletrorretinograma de campo total mostrou diminuição da amplitude das respostas das ondas a e b no olho afetado comparado com o olho sadio. A tomografia de coerência óptica mostrou alterações significativas nas camadas retinianas externas no olho comprometido. A toxicidade do melfalan é dose dependente e, apesar dos benefícios terapêuticos, podem causar alterações retinianas significativas. Este caso demonstra uma avaliação atual e aprofundada da toxicidade retiniana do melfalan intravítreo na retina humana através da tomografia de coerência óptica e sua correlação com as alterações no eletrorretinograma.

RESUMO

ABSTRACT Purpose: The regulatory effect of microRNA on diseases has been confirmed. This study aimed to evaluate the expression of microRNA-210-3p in age-related cataracts and assess the effect of abnormal miR-210-3p expressions on H2O2-induced SAR01/04 cells. Methods: Reverse-transcription quantitative polymerase chain reaction method was performed to assess the levels of miR-210-3p in aqueous humor samples. Receiver operating characteristic analysis was employed to assess the discrimination ability of miR-210-3p between patients with age-related cataracts and healthy people, and Pearson correlation analysis was used to identify the correlation between miR-210-3p and oxidative stress indices such as superoxide dismutase, glutathione peroxidase, malonaldehyde. Cell counting kit-8 assay and Transwell assay were used to estimate the biological function of H2O2-induced age-related cataract cell model. The levels of oxidative stress indices such as superoxide dismutase, glutathione peroxidase, and malonaldehyde were measured to evaluate the degree of oxidative stress damage in the age-related cataract cell model. The relationship between miR-210-3p and its target gene was verified by luciferase reporter gene analysis. Results: The miR-210-3p expression was elevated in the aqueous humor of patients with age-related cataracts. A high miR-210-3p expression showed a high diagnostic value for age-related cataracts and was significantly associated with the level of oxidative stress markers in patients with age-related cataracts. The inhibition of miR-210-3p can reverse oxidative stress stimulation and adverse effects on H2O2-induced cell function. Conclusions: The results suggested that miR-210-3p could promote cell viability, cell migration, and oxidative stress by targeting autophagy-related gene 7 in in vitro age-related cataract cell model.


RESUMO Objetivo: O efeito regulador do microRNA em doenças tem sido confirmado, e este artigo tentou avaliar a expressão do microRNA-210-3p na catarata relacionada à idade e avaliar o efeito da expressão anormal do miR-210-3p em células SAR01/04 induzidas por H2O2. Métodos: O método de transcrição reversa seguida de reação em cadeia da polimerase (RT-PCR) quantitativa foi realizado para avaliar os níveis de miR-210-3p em amostras de humor aquoso. Análise de características operacionais do receptor foi feita para avaliar a capacidade de discriminação do miR-210-3p entre pacientes com catarata relacionada à idade e pessoas saudáveis. A análise de correlação de Pearson identificou a correlação do miR-210-3p e índices de estresse oxidativo, como superóxido dismutase, glutationa peroxidase, malonaldeído. O ensaio de contagem de células kit-8 (cck-8) e o ensaio no sistema Transwell foram utilizados para estimar a função biológica do formato de células de catarata relacionada com a idade induzida por H2O2. Os níveis de índices de estresse oxidativo como superóxido dismutase, glutationa peroxidase e malonaldeído foram detectados para avaliar o grau de dano do estresse oxidativo em formato de células de catarata relacionada à idade. A relação entre miR-210-3p e seu gene alvo foi verificada por análise do gene repórter luciferase. Resultados: A expressão miR-210-3p foi elevada no humor aquoso de pacientes com catarata relacionada à idade. A expressão miR-210-3p altamente expressiva mostrou alto valor diagnóstico para catarata relacionada à idade e foi significativamente associado ao nível de marcadores de estresse oxidativo em pacientes com catarata relacionada à idade. A inibição de miR-210-3p pode reverter a estimulação do estresse oxidativo e os efeitos adversos da função celular induzida por H2O2. Conclusões: Esses dados sugeriram que a expressão miR-210-3p poderia promover a viabilidade celular, migração celular e estresse oxidativo ao direcionar genes ATG 7 relacionados à autofagia em modelo in vitro de células de catarata relacionadas à idade.

RESUMO

Resumo O presente estudo objetivou investigar a associação entre o TEA e o uso materno e paterno de medicamentos, tabaco, álcool e drogas ilícitas. Trata-se de um estudo caso-controle realizado com crianças e adolescentes diagnosticados com TEA e indivíduos neurotípicos. Os dados foram colhidos por meio de entrevista com as mães ou responsáveis. Foram analisadas as variáveis sexo e idade das crianças/adolescentes; idade dos pais; uso de medicamentos antes e durante a gestação; classes de medicamentos usados na gestação; tabagismo materno e paterno; etilismo materno e paterno; uso de drogas ilícitas pelos pais. Para a análise das informações, utilizou-se o modelo de regressão logística, além da razão de chances (OR) bruta e ajustada. Os resultados mostraram que, após os ajustes, foi encontrada associação entre o uso materno na gestação de antitérmicos/analgésicos (OR = 2,26; IC95% 1,29-3,95; p < 0,040) com o TEA. Já o uso de tabaco, álcool e drogas ilícitas materno e paterno, antes e durante a gestação, não apontou relação com o TEA. Os dados encontrados sugerem que existe influência de fatores ambientais no desenvolvimento do TEA.


Abstract The aim of this study was to investigate the association between maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder (ASD). We conducted a case-control study with children and adolescents diagnosed with ASD and neurotypical individuals. The data were collected using a semi-structured questionnaire administered during interviews with the children's mothers or guardians. The following variables were analyzed: child sex and age; maternal and parental age; use of medicines before and during pregnancy; classes of medicines used during pregnancy; maternal and paternal smoking; maternal and paternal drinking; maternal and paternal illicit drug use. The data were analyzed using logistic regression and crude and adjusted odds ratios (OR). After adjustment, the results showed an association between maternal use of antipyretics/pain killers during pregnancy (OR = 2.26; 95%CI 1.29-3.95; p < 0.040) and ASD. No association was found between maternal and paternal smoking, drinking and illicit drug use before and during pregnancy and ASD. The findings suggest that the development of ASD is influenced by environmental factors.

RESUMO

ABSTRACT A 60-year-old-male with refractory relapsed multiple myeloma presented with redness, pain, foreign body sensation, and blurred vision in both eyes that gradually increased after his third belantamab mafotodin infusion. Biomicroscopy revealed bilateral microcyst-like epithelial changes and epithelial crystal-like deposits, whereas in vivo confocal microscopy revealed intraepithelial and subepithelial hyperreflective deposits in corneal epithelium. Belantamab mafodotin therapy was discontinued for seven weeks due to corneal toxicity, which cleared progressively. We aim to demonstrate belantamab mafodotin-related corneal toxicity that may be detected using slit lamp and in vivo confocal biomicroscopy.


RESUMO Um homem de 60 anos, diagnosticado com mieloma múltiplo recidivante refratário, apresentou vermelhidão, dor, sensação de corpo estranho e visão turva em ambos os olhos, aumentando gradualmente após sua terceira infusão de belantamabe mafodotina. À biomicroscopia, foram observadas alterações epiteliais bilaterais semelhantes a microcistos e depósitos epiteliais semelhantes a cristais. A microscopia confocal in vivo revelou depósitos hiper-refletivos intraepiteliais e subepiteliais na córnea. Devido à toxicidade corneana, a terapia com belantamabe mafodotina foi interrompida por sete semanas e a toxicidade foi gradualmente resolvida. Nosso objetivo é demonstrar os achados à biomicroscopia confocal in vivo e à lâmpada de fenda da toxicidade corneana relacionada ao belantamabe mafodotina.

RESUMO

Abstract In dermatologists' clinical practice, the use of systemic glucocorticoids is recurrent for the management of different comorbidities that require chronic immunosuppression. The prescription of this medication requires caution and basic clinical knowledge due to the several adverse effects inherent to the treatment. However, different doubts may arise or inappropriate conduct may be adopted due to the lack of objective and specific guidelines for the screening, prophylaxis and management of complications from chronic corticosteroid therapy. Considering this problem, the authors carried out a narrative review of the literature to gather up-to-date data on adverse effects secondary to the chronic use of systemic glucocorticoids. The broad approach to this topic made it possible to review the pathophysiology and risk factors for these complications, as well as to develop updated orientation that can be used as a learning tool and quick reference for dermatologists during their clinical practice with glucocorticoids.

RESUMO

Abstract Background Glomus Tumor (GT) are benign neoplasms that originate from mesenchymal cells. It presents as tenderness and cold allodynia in the digits, especially in the subungual region. There are a few studies that investigated the mechanism of pain. Objectives To analyze the clinical-pathologic characteristics of GT and to identify the expression of IL-1β, IL-6, and CGRP in it, further, to explore the possible mechanism of pain. Methods The clinical and pathological data of 60 GT patients were retrospectively analyzed. Tissue microarrays and immunohistochemistry were used to measure the expression of IL-1β, IL-6 and CGRP. Results GT is more common in females and the ratio of male to was near to 1:2, mostly in middle-aged people. It often occurs in fingertips, especially the thumbs. Patients often present with spontaneous pain, tenderness, and cold hypersensitivity. Both the two pain mediators IL-1β and IL-6 were highly expressed in GT cells of patients with and without cold hypersensitivity. While CGRP was not expressed in GT. Study limitations Low sample size and further research is needed to explore the specific mechanism. Conclusions IL-1β and IL-6 were highly expressed in GT cells, suggesting that IL-1β and IL-6 have certain nociceptive roles in GT. In the 4 patients with cold intolerance, the intensity of IL-1β and IL-6 staining was also strong, suggesting that they may not play a role in the cold hypersensitivity. However, since there are only 4 patients with cold intolerance, it's necessary to conduct further in-depth research using a larger sample size. The specific role of CGRP in GT has not been found yet.

RESUMO

ABSTRACT Bilateral acute depigmentation of the iris and bilateral acute iris transillumination (BAIT) are similar clinical entities. The former causes acute-onset depigmentation of the iris stroma without transillumination, whereas the latter causes depigmentation of the iris pigment epithelium with transillumination. The etiopathogenesis of these conditions is not yet fully understood, but the proposed causes include the use of systemic antibiotics (especially moxifloxacin) and viral triggers. We present a case series of five female patients with a mean age of 41 (32-45) years, all of whom suffered acute onset of bilateral pain and redness of the eyes after moxifloxacin use (oral or topical). It is important for ophthalmologists to be aware of the two forms of iris depigmentation since this case series suggests that SARS-CoV-2 or its empirical treatment with moxifloxacin may trigger iris depigmentation. If this is the case, clinicians will likely see increased incidences of bilateral acute depigmentation of the iris and bilateral acute iris transillumination during and after the COVID-19 pandemic.
