Hyaluronic acid-mediated epithelial-mesenchymal transition of human lens epithelial cells via CD44 and TGF-β2

ABSTRACT Purpose: The epithelial-mesenchymal transition of human lens epithelial cells plays a role in posterior capsule opacification, a fibrotic process that leads to a common type of cataract. Hyaluronic acid has been implicated in this fibrosis. Studies have investigated the role of transforming growth factor (TGF)-β2 in epithelial-mesenchymal transition. However, the role of TGF-β2 in hyaluronic acid-mediated fibrosis of lens epithelial cell remains unknown. We here examined the role of TGF-β2 in the hyaluronic acid-mediated epithelial-mesenchymal transition of lens epithelial cells. Methods: Cultured human lens epithelial cells (HLEB3) were infected with CD44-siRNA by using the Lipofectamine 3000 transfection reagent. The CCK-8 kit was used to measure cell viability, and the scratch assay was used to determine cell migration. Cell oxidative stress was analyzed in a dichloro-dihydro-fluorescein diacetate assay and by using a flow cytometer. The TGF-β2 level in HLEB3 cells was examined through immunohistochemical staining. The TGF-β2 protein level was determined through western blotting. mRNA expression levels were determined through quantitative real-time polymerase chain reaction. Results: Treatment with hyaluronic acid (1.0 μM, 24 h) increased the epithelial-mesenchymal transition of HLEB3 cells. The increase in TGF-β2 levels corresponded to an increase in CD44 levels in the culture medium. However, blocking the CD44 function significantly reduced the TGF-β2-mediated epithelial-mesenchymal transition response of HLEB3 cells. Conclusions: Our study showed that both CD44 and TGF-β2 are critical contributors to the hyaluronic acid-mediated epithelial-mesenchymal transition of lens epithelial cells, and that TGF-β2 in epithelial-mesenchymal transition is regulated by CD44. These results suggest that CD44 could be used as a target for preventing hyaluronic acid-induced posterior capsule opacification. Our findings suggest that CD44/TGF-β2 is crucial for the hyaluronic acid-induced epithelial-mesenchymal transition of lens epithelial cells.

Choroiditis following severe acute respiratory syndrome coronavirus 2 infection in unvaccinated identical twins

ABSTRACT Unvaccinated identical twins developed bilateral anterior uveitis soon after the onset of coronavirus disease 2019 symptoms. During follow-up, both patients developed choroiditis, and one twine developed posterior scleritis and serous retinal detachment. Prompt treatment with oral prednisone ameliorated the lesions, and no recurrence was observed at the 18-month follow-up. Choroiditis may rarely be associated with severe acute respiratory syndrome coronavirus 2 infection, and it responds well to corticosteroid therapy. Although the exact mechanism is unknown, we hypothesize that the virus may act as an immunological trigger for choroiditis.

Sodium-glucose cotranspor ter 2 (SGLT2) inhibitors in nephrolithiasis: should we "gliflozin" patients with kidney stone disease? / Inibidores de cotransportadores sódio-glicose-2 (SGLT2) na nefrolitíase - devemos "gliflozinar" os litiásicos?

ABSTRACT The prevalence of nephrolithiasis is increasing worldwide. Despite advances in understanding the pathogenesis of lithiasis, few studies have demonstrated that specific clinical interventions reduce the recurrence of nephrolithiasis. The aim of this review is to analyze the current data and potential effects of iSGLT2 in lithogenesis and try to answer the question: Should we also "gliflozin" our patients with kidney stone disease?

RESUMO A prevalência da nefrolitíase está aumentando em todo o mundo. Apesar dos avanços na compreensão da patogênese da doença litiásica, poucos estudos demonstraram que intervenções clínicas específicas diminuem a recorrência da nefrolitíase. O objetivo desta revisão é analisar os dados atuais e efeitos potenciais dos iSGLT2 na doença litiásica e tentar responder à pergunta: devemos também "gliflozinar" os litiásicos?

Factores relacionados con la supervivencia en una cohorte de pacientes con enfermedad pulmonar obstructiva crónica grave a largo plazo: relación con la capacidad aeróbica / Related Factors for Survival in a Cohort of Patients with Severe Chronic Obstructive Pulmonary Disease in a Long-Term of Follow-Up: Relationship with Aerobic Capacity

Introducción: Sólo Oga et al. (AJRCCM 2003) relacionaron supervivencia y capacidad aeróbica en pacientes EPOC, pero en hombres y seguimiento a 5 años. Objetivos: Evaluar la supervivencia de una cohorte de pacientes EPOC grave según el consumo de oxígeno pico (VO2p) ajustado al peso. Material y Métodos: Se evaluó la supervivencia a largo plazo desde el diagnóstico de pacientes con EPOC (GOLD). Se midió el VO2p ajustado por peso en prueba cicloergo- métrica máxima (gases espirados). Se usaron técnicas estadísticas convencionales y análisis de supervivencia de LogRank (Mantel-Cox). Resultados: 70 pacientes (27% femenino); edad 68 años (RIQ 63-73); %FEV1 postBD: 39,95±2,09; VO2p: 9,25 ± 3,17 ml/kg/min. GOLD D/B/A 84,3/14,2/1,5%; GOLD II/III/IV: 15,7/61,4/22,9%. A 14 años de seguimiento, 75% había fallecido. Supervivencia: primer cuartilo de VO2p (ml/kg/min) fue 38,5 meses (RIQ 18,25-58,5) y para el cuarto cuartilo 68 meses (RIQ 48-93). A 103 meses, la diferencia en supervivencia fue: primer cuartilo vs. cuarto cuartilo de VO2p (p<0,01) y segundo vs. cuarto cuartilo (p<0,03); a 145 meses entre segundo vs. cuarto cuartilo (p=0,049). En el análisis multivariado, el VO2p alto es un factor protector sobre la mortalidad. En cambio, otras variables independientes como sexo masculino, edad >70, grado de obstrucción bronquial severo y fenotipo exacerbador frecuente se asociaron a mortalidad. Conclusión: A largo plazo, en una cohorte de pacientes hombres y mujeres EPOC grave, en análisis multivariado, el VO2p alto es factor protector sobre la mortalidad. En cambio, otras variables independientes como sexo masculino, edad >70, grado de obstrucción bronquial severo y exacerbador frecuente se asociaron a mortalidad.

Introduction: Only Oga et al. (AJRCCM 2003) related survival and aerobic capacity, but only in chronic obstructive pulmonary disease (COPD) men with 5 years of follow-up. Objective: To determine survival in a cohort of patients with severe COPD due to aerobic capacity (VO2max) adjusted by weight. Methods: Survival of COPD patients was evaluated to long-term (GOLD definition). Patients performed maximal exercise test in cicloergometry (expired gases) evaluating (VO2max). Conventional statistics and Log-Rank survival analysis (Mantel-Cox) were used. Results: We included 70 patients (27% female) followed up 60.77 months (RIQ 29- 87.85); age 68 years (RIQ 63-73); %FEV1 postBD: 39.95±2.09; VO2p: 9.25± 3.17 ml/kg/ min. GOLD D/B/A 84.3/14.2/1.5%; GOLD II/III/IV: 15.7/61.4/22.9%. After 14 years of follow-up, 75% of patients died. Survival: VO2p (ml/kg/min) first quartil was 38.5 months (RIQ 18,25-58,5); second quartil 66 months (RIQ 35-84.5); third quartil 70 months (RIQ 15-96) and fourth quartil 68 months (RIQ 48-93). After 103 months of follow-up, survival was compared: 1st vs 4rd quartil of VO2p (p<0.01) and 2nd vs. 4rd quartil (p<0.03); comparing at 145 months: 2nd vs. 4rd quartil (p=0.049). In a multivariate analysis, high VO2p is a protective factor on mortality, nevertheless other independent variables as male gender, age >70, severe airway obstruction and frequent exacerbators were associated to mortality. Conclusion: At long term of follow-up, a cohort of severe COPD patients (males and fe- males), in multivariate analysis, high VO2p is a protective factor of mortality, nevertheless other independent variables as male gender, age >70, severe airway obstruction and frequent exacerbators were associated to mortality.

Morphological and Morphometric Analysis, Apoptosis and Oxidative Stress Study in Hep 2 Cells Treated by Resveratrol or Quercetine / Análisis Morfológico y Morfométrico, Estudio de Apoptosis y Estrés Oxidativo en Células Hep 2 Tratadas con Resveratrol o Quercetina

SUMMARY: Resveratrol (RES) and quercetine (QRC), is a promising agent relevant for both cancer chemoprevention and treatment via several signaling pathways, involved in their anticancer activity related to its chemotherapeutic potential, associated with the induction of ROS generation in cancer cells, leading to apoptosis. In our study, we have summarized the mechanisms of action of RES and QRC, and their pharmacological implications and potential therapeutic applications in cancer therapy. After treatment of Hep 2 cells with QRC or RES, the death pathways such as the cytochrome c release, ERK1/2 and IRS-1 pathways were upregulated, while cell survival pathway, including PI3K/AKT were downregulated. The RES and QRC caused oncosis, cells hypertrophy, hypercondensatin of chromatin, rupture of the plasma membrane and nuclear membrane, and formation of apoptotic bodies. Morphometric measurements of some cellular and nuclear parameters showed that RES and QRC induced an increase in cells and nuclear size, the nucleocytoplasmic ratio remained below 1 (N-Cyt R < 1), sign of low nuclear activity. The RES and QRC induced apoptosis of Hep2 cells by increasing of oxidative stress markers, MDA, and by modulating detoxifying enzymes, CAT and SOD. Our study results prove antiproliferative and proapoptotic properties of quercetin and resveratrol with regard to larynx cancer.

Resveratrol (RES) y quercetina (QRC), es un agente prometedor y relevante tanto para la quimioprevención como para el tratamiento del cáncer a través de varias vías de señalización, involucrado en su actividad anticancerígena relacionada con su potencial quimioterapéutico, asociado con la inducción de la generación de especies reactivas del oxígeno (ROS) en células cancerosas, lo que lleva a apoptosis. En nuestro estudio, hemos resumido los mecanismos de acción de RES y QRC, y sus implicaciones farmacológicas y posibles aplicaciones terapéuticas en la terapia del cáncer. Después del tratamiento de las células Hep 2 con QRC o RES, las vías de muerte, tal como la liberación de citocromo c, las vías ERK1/2 e IRS-1, se regulaban positivamente, mientras que la vía de supervivencia celular, incluida PI3K/AKT, se regulaba negativamente. El RES y el QRC provocaron oncosis, hipertrofia celular, hipercondensación de la cromatina, rotura de la membrana plasmática y nuclear y formación de cuerpos apoptóticos. Las mediciones morfométricas de algunos parámetros celulares y nucleares mostraron que RES y QRC indujeron un aumento en las células y el tamaño nuclear, la proporción nucleocitoplasmática se mantuvo por debajo de 1 (N- Cyt R <1), signo de baja actividad nuclear. RES y QRC indujeron la apoptosis de las células Hep2 aumentando los marcadores de estrés oxidativo, MDA, y modulando las enzimas desintoxicantes, CAT y SOD. Los resultados de nuestro estudio demuestran las propiedades antiproliferativas y proapoptóticas de la quercetina y el resveratrol con respecto al cáncer de laringe.

La relación entre la vacunación con COVID-19 y la irregularidad menstrual: ¿qué se ha descrito en la bibliografía?

En marzo de 2020, la Organización Mundial de la Salud decretó la pandemia de COVID-19 y para prevenir los casos de Síndrome Respiratorio Agudo Severo y otras complicaciones una de las medidas adoptadas fue la vacunación contra el COVID-19. El virus SARS-CoV-2, responsable del COVID-19, penetra en las células huésped a través de los receptores de la enzima convertidora de angiotensina II que se expresan en diversos órganos como el útero y los ovarios. Hasta el último trimestre de 2021, se han aprobado en todo el mundo unas doce vacunas, en seis categorías diferentes, contra el COVID-19, y entre los efectos adversos se han notificado irregularidades menstruales. En varios estudios se mencionan alteraciones del ciclo menstrual tales como alteración de la duración del ciclo, aumento del flujo menstrual, dismenorrea y amenorrea de 7 a 30 días después de la administración de la última dosis de COVID-19. También se observó en estos estudios que mujeres que no presentaban irregularidades después de la primera dosis de la vacuna, empezaron a tenerlas después de la segunda dosis. En general, las anormalidades del ciclo menstrual cesan dentro de los 3 meses después de la última dosis de la vacuna y no hay un impacto definitivo sobre la fertilidad de la mujer.

In March 2020, the World Health Organization decreed the COVID-19 pandemic and to avoid cases of Severe Acute Respiratory Syndrome and other complications, one of the measures adopted was vaccination for COVID-19. The SARS-CoV-2 virus, responsible for COVID-19, enters host cells through angiotensin II converting enzyme receptors that are expressed in various organs such as the uterus and ovaries. Until the last quarter of 2021, around the world, about twelve vaccines were approved, in six different categories, for COVID-19 and among the adverse effects there was the report of menstrual irregularities. In several studies, changes in the menstrual cycle are mentioned, such as changes in the duration of the cycle, increased menstrual flow, dysmenorrhea and amenorrhea from 7 to 30 days after the administration of the last dose for COVID-19. It was also observed in these studies that women who did not have irregularities after the first dose of the vaccine started to have them after the second dose. In general, changes in the menstrual cycle cease within 3 months after the last dose of the vaccine and there is no definitive impact on the woman's fertility. (provided by Infomedic Intl)

Caracterización de nuevos genes implicados en metástasis en cáncer de próstata

Introducción: Nuestro trabajo aborda una revisión bibliográfica realizada entre enero de 2019 y septiembre de 2023, se resalta la importancia de los genes BRCA1, BRCA2, AR y PTEN en la patogénesis, pronóstico y tratamiento del cáncer de próstata, especialmente en su forma metastásica resistente a la castración (mCRPC). Los genes BRCA1 y BRCA2 se identifican como marcadores clave para prever la agresividad del cáncer, sugiriendo la necesidad de terapias dirigidas y vigilancia estricta. La adaptabilidad de las células cancerosas y la variabilidad en la expresión del receptor de andrógenos (AR) limitan la efectividad de las terapias centradas únicamente en AR, señalando la importancia de identificar vías alternativas y biomarcadores para un tratamiento más efectivo. La función de PTEN se relaciona directamente con la progresión de la enfermedad, y su alteración sugiere posibles enfoques terapéuticos. Sin embargo, la heterogeneidad de las células cancerosas y la complejidad de las vías moleculares presentan desafíos significativos para el desarrollo de terapias universales. Conclusión: Los hallazgos promueven la investigación futura para confirmar la aplicabilidad de estos genes como biomarcadores y desarrollar estrategias de tratamiento personalizadas en el cáncer de próstata.

Introduction: Our work addresses a literature review conducted between January 2019 and September 2023, the importance of BRCA1, BRCA2, AR and PTEN genes in the pathogenesis, prognosis and treatment of prostate cancer, especially in its metastatic castration-resistant form (mCRPC), is highlighted. BRCA1 and BRCA2 genes are identified as key markers for predicting cancer aggressiveness, suggesting the need for targeted therapies and strict surveillance. The adaptability of cancer cells and variability in androgen receptor (AR) expression limit the effectiveness of therapies focused solely on AR, pointing to the importance of identifying alternative pathways and biomarkers for more effective treatment. PTEN function is directly related to disease progression, and its alteration suggests potential therapeutic approaches. However, the heterogeneity of cancer cells and complexity of molecular pathways present significant challenges to the development of universal therapies. Conclusion: The findings promote future research to confirm the applicability of these genes as biomarkers and to develop personalized treatment strategies in prostate cancer.

Repercussions of the COVID-19 pandemic on breast cancer actions in a Brazilian state / Repercusiones de la pandemia de COVID-19 en las acciones contra el cáncer de mama en un estado brasileira / Repercussões a pandemia da COVID-19 nas ações do câncer de mama em um Estado Brasileiro

Objective. To analyze whether the COVID-19 pandemic had an impact on the screening, diagnosis and treatment of breast cancer in women up to 50 years of age in the state of Pará. Methods. Retrospective, cross-sectional study with a quantitative approach, using data from the Information Technology Department of the Brazilian Unified Health System. (DATASUS). The number of exams carried out in the pre-pandemic (2018-2019) and pandemic (2020-2021) period was analyzed based on the percentage variation, application of the chi-square test and G test for the time of exams and start time of treatment. Results. During the pandemic period, there was a greater number of screening mammograms (+3.68%), cytological (+23.68%), histological (+10.7%) and a lower number of diagnostic mammograms (-38.7%). The time interval for carrying out the exams was up to 30 days for screening and diagnostic exams and more than 60 days to start treatment during the pandemic period. Conclusion. Although the results indicate an increase in the number of screening and diagnostic procedures for breast cancer during the pandemic period, with the exception of diagnostic mammography, when considering probability values, the study points out that statistically the COVID-19 pandemic did not interfere with actions of breast cancer, in women over 50 years of age, in the state of Pará. Considering the autonomy of nursing and its role in public health, it is up to the professionals who are in charge of primary care programs to implement contingency plans in periods of crisis so that the population is not left unassisted.

Objetivo. Analizar si la pandemia de COVID-19 tuvo impacto en el tamizaje, diagnóstico y tratamiento del cáncer de mama en mujeres de 50 años y más del Estado do Pará-Brasil. Métodos. Estudio retrospectivo, transversal, con abordaje cuantitativo, en el que se utilizaron los datos del Departamento de Informática del Sistema Único de Salud de Brasil (DATASUS). Se comparó el número de exámenes realizados y el tiempo para el inicio de tratamiento en los períodos prepandémico (2018-2019) y pandémico (2020-2021). Resultados. Se observó un mayor número de mamografías de cribado (+3.68%), citologías (+23.68%) e histologías (+10.7%) y un menor número de mamografías diagnósticas (-38.7%) en el período pandémico. El tiempo para la realización de las pruebas fue de hasta 30 días para el cribado y diagnóstico y de más de 60 días para el inicio del tratamiento durante el período pandémico. Conclusión. Aunque los resultados indican un aumento del número de procedimientos de cribado y diagnóstico del cáncer de mama en el periodo pandémico, con la excepción de la mamografía diagnóstica, cuando consideramos los valores de p) el estudio muestra que la pandemia COVID-19 estadísticamente no interfirió en las acciones preventivas contra el cáncer de mama en mujeres de 50 años y más en el estado de Pará. Teniendo en cuenta la autonomía de la enfermería y su papel en la salud pública, corresponde a los profesionales responsables de los programas de atención primaria implementar planes de contingencia en tiempos de crisis para no dejar desatendida a la población.

Objetivo. Analisar se a pandemia da COVID-19 repercutiu no rastreamento, diagnóstico e tratamento do câncer de mama em mulheres paraenses a partir de 50 anos. Métodos. Estudo retrospectivo, transversal, de abordagem quantitativa, com utilização de dados do Departamento de Informática do Sistema Único de Saúde brasileiro. (DATASUS). Analisou-se o número de exames realizados no período pré-pandemia (2018-2019) e pandêmico (2020-2021) com base na variação percentual, aplicação do teste qui quadrado e teste G para o tempo de realização de exames e tempo de início de tratamento. Resultados. Observou-se no período pandêmico maior quantitativo de mamografias de rastreamento (+3.68%), citológicos (+23.68%), histológicos (+10.7%) e menor registro de mamografias diagnósticas (-38.7%). O intervalo de tempo para realização dos exames foi de até 30 dias para os exames de rastreamento e diagnóstico e tempo maior que 60 dias para início de tratamento no período pandêmico. Conclusão. Embora os resultados indiquem aumento no quantitativo de procedimentos de rastreamento e diagnósticos para o câncer de mama no período pandêmico, com exceção da mamografia diagnóstica, ao considerarmos os valores de probabilidade, o estudo aponta que estatisticamente a pandemia da COVID-19 não interferiu nas ações do câncer de mama, em mulheres a partir de 50 anos, no Estado do Pará. Considerando a autonomia da enfermagem e sua atuação na saúde pública, cabe aos profissionais que estão à frente dos programas da atenção básica implementar planos de contingência em períodos de crise para que a população não fique desassistida.

Concordancia diagnóstica de las imágenes torácicas para enfermedad por Covid-19 / Diagnostic concordance of thoracic images for Covid-19 disease

La reacción en cadena de la polimerasa de transcripción inversa (RT-PCR) es el estándard de oro para el diagnóstico de enfermedad por SARS-CoV-2. En el contexto de la pandemia con accesibilidad limitada a esta prueba, las imágenes diagnósticas aportaron hallazgos que sustentan la sospecha diagnóstica, evitando retrasos en atención médica. Objetivo. Determinar la sensibilidad, especificidad, valor predictivo positivo y negativo de las imágenes diagnósticas y su concordancia respecto al resultado de RT-PCR. Metodología. Estudio transversal analítico. Se comparó el resultado del reporte por imágenes con los resultados de RT-PCR en 138 pacientes. Se calculó la sensibilidad, especificidad, valor predictivo positivo y valor predictivo negativo para los rayos X de tórax y tomografía computarizada para el diagnóstico de infección por SARS-CoV-2. Se utilizó el índice Kappa de Cohen y el factor de Bayes para medir la concordancia y fuerza de asociación entre las variables. Resultados. La tomografía computarizada presentó una sensibilidad de 92,9 %, una especificidad del 64 %, un valor predictivo positivo de 92,1 % y un valor predictivo negativo de 66,7 %; mientras que, los rayos X presentaron una sensibilidad del 86 %, una especificidad del 52,9 %, un valor predictivo positivo de 92,9 % y un valor predictivo negativo del 34,6 %. Conclusión. La tomografía mostró concordancia diagnóstica moderada; su utilidad es mayor en casos de sospecha clínica moderada-alta, discrepancia diagnóstica o confirmación de complicaciones. Los rayos X mostraron concordancia diagnóstica baja; este método es de utilidad en casos de alta sospecha clínica, pero necesita comprobación con RT-PCR para un diagnóstico definitivo.

Reverse transcription polymerase chain reaction (RT-PCR) is the gold standard method for diagnosing SARS-CoV-2 disease. However, due to limited accessibility to this test during the pandemic, diagnostic imaging was used to support diagnostic suspicion and avoid delays in medical care. Objective. Determine the accuracy of diagnostic imaging (chest X-ray and computed tomography) in diagnosing SARS-CoV-2 infection, compared to RT-PCR result. Methodology.An analytical cross-sectional study was conducted. The imaging reports of 138 patients were compared with their RT-PCR results to calculate sensitivity, specificity, positive predictive value, and negative predictive value for both chest X-ray and computed tomography. Concordance between the imaging results and RT-PCR was measured using Cohen's Kappa index and Bayes factor. Results. Computed tomography showed a sensitivity of 92.9 %, a specificity of 64 %, a positive predictive value of 92.1 %, and a negative predictive value of 66.7 %. On the other hand, X-rays showed a sensitivity of 86 %, a specificity of 52.9 %, a positive predictive value of 92.9 %, and a negative predictive value of 34.6 %. Conclusion. Computed tomography showed moderate diagnostic concordance and is particularly useful in cases of moderate to high clinical suspicion, diagnostic discrepancy, or the need to confirm complications. On the other hand, X-rays showed low diagnostic concordance and should be used in combination with RT-PCR for a definitive diagnosis, especially in cases of high clinical suspicion

Risk factors for acute kidney injury in patients hospitalized with COVID-19 / Fatores de risco para lesão renal aguda em pacientes hospitalizados com COVID-19

Abstract Introduction: Acute kidney injury (AKI) occurs frequently in COVID-19 patients and is associated with greater morbidity and mortality. Knowing the risks of AKI allows for identification, prevention, and timely treatment. This study aimed to identify the risk factors associated with AKI in hospitalized patients. Methods: A descriptive, retrospective, cross-sectional, and analytical component study of adult patients hospitalized with COVID-19 from March 1 to December 31, 2020 was carried out. AKI was defined by the creatinine criteria of the KDIGO-AKI guidelines. Information, regarding risk factors, was obtained from electronic medical records. Results: Out of the 934 patients, 42.93% developed AKI, 60.59% KDIGO-1, and 9.9% required renal replacement therapy. Patients with AKI had longer hospital stay, higher mortality, and required more intensive care unit (ICU) admission, mechanical ventilation, and vasopressor support. Multivariate analysis showed that age (OR 1.03; 95% CI 1.02-1.04), male sex (OR 2.13; 95% CI 1.49-3.04), diabetes mellitus (DM) (OR 1.55; 95% CI 1.04-2.32), chronic kidney disease (CKD) (OR 2.07; 95% CI 1.06-4.04), C-reactive protein (CRP) (OR 1.02; 95% CI 1.00-1.03), ICU admission (OR 1.81; 95% CI 1.04-3.16), and vasopressor support (OR 7.46; 95% CI 3.34-16.64) were risk factors for AKI, and that bicarbonate (OR 0.89; 95% CI 0.84-0.94) and partial pressure arterial oxygen/inspired oxygen fraction index (OR 0.99; 95% CI 0.98-0.99) could be protective factors. Conclusions: A high frequency of AKI was documented in COVID-19 patients, with several predictors: age, male sex, DM, CKD, CRP, ICU admission, and vasopressor support. AKI occurred more frequently in patients with higher disease severity and was associated with higher mortality and worse outcomes.

A análise multivariada mostrou que idade (OR 1,03; IC 95% 1,02-1,04), sexo masculino (OR 2,13; IC 95% 1,49-3,04), diabetes mellitus (DM) (OR 1,55; IC 95% 1,04-2,32), doença renal crônica (DRC) (OR 2,07; IC 95% 1,06-4,04), proteína C reativa (PCR) (OR 1,02; IC 95% 1,00-1,03), admissão em UTI (OR 1,81; IC 95% 1,04-3,16) e suporte vasopressor (OR 7,46; IC 95% 3,34-16,64) foram fatores de risco para LRA, e que bicarbonato (OR 0,89; IC 95% 0,84-0,94) e índice de pressão parcial de oxigênio arterial/fração inspirada de oxigênio (OR 0,99; IC 95% 0,98-0,99) poderiam ser fatores de proteção. Conclusões: Documentou-se alta frequência de LRA em pacientes com COVID-19, com diversos preditores: idade, sexo masculino, DM, DRC, PCR, admissão em UTI e suporte vasopressor. LRA ocorreu mais frequentemente em pacientes com maior gravidade da doença e associou-se a maior mortalidade e piores desfechos.

Histological and Endocrine Effects of Chronic Exposure to MP2.5 Derived from Wood Smoke in the Uterus of Nulliparous Adult Rats

SUMMARY: The study explores the relationship between chronic exposure to fine particulate matter (PM2.5), sourced from wood smoke, and the histological structure and endocrine function of the uterus in nulliparous adult rats. It assesses potential structural changes in the uterus that could impact reproductive health, viewing PM2.5 exposure as a possible risk factor. A controlled experiment was conducted in a city known for high air pollution levels, exposing rats to filtered and unfiltered air conditions, thus mimicking human PM2.5 exposure. Histological findings indicated a significant increase in collagen density and uterine wall thickness in PM2.5 exposed subjects, suggesting a reproductive function risk. However, no significant differences were observed in progesterone and estradiol hormone levels, pointing to the complex relationship between PM2.5 exposure and its endocrine impact, and emphasizing the need for further studies for a deeper understanding. This work highlights the importance of thoroughly investigating the long-term effects of PM2.5 pollution on reproductive health, underlining the significance of considering environmental exposure as a critical factor in reproductive health research.

El estudio explora la relación entre la exposición crónica a partículas finas (PM2,5), procedentes del humo de leña, y la estructura histológica y la función endocrina del útero en ratas adultas nulíparas. Evalúa posibles cambios estructurales en el útero que podrían afectar la salud reproductiva, considerando la exposición a PM2,5 como un posible factor de riesgo. Se llevó a cabo un experimento controlado en una ciudad conocida por sus altos niveles de contaminación del aire, exponiendo ratas a condiciones de aire filtrado y sin filtrar, imitando así la exposición humana a PM2,5. Los hallazgos histológicos indicaron un aumento significativo en la densidad del colágeno y el grosor de la pared uterina en sujetos expuestos a PM2,5, lo que sugiere un riesgo para la función reproductiva. Sin embargo, no se observaron diferencias significativas en los niveles de las hormonas progesterona y estradiol, lo que apunta a la compleja relación entre la exposición a PM2,5 y su impacto endocrino, y enfatiza la necesidad de realizar más estudios para una comprensión más profunda. Este trabajo destaca la importancia de investigar a fondo los efectos a largo plazo de la contaminación por PM2,5 en la salud reproductiva, subrayando la importancia de considerar la exposición ambiental como un factor crítico en la investigación de la salud reproductiva.

Função do Ventrículo Direito e Estresse Oxidativo Melhoram com a Administração de Hormônios da Tireoide e Suco de Uva em um Modelo de Hipertensão Pulmonar / Right Ventricular Function and Oxidative Stress Improve with the Administration of Thyroid Hormones and Grape Juice in a Pulmonary Hypertension Model

Resumo Fundamento A remodelação adversa dos vasos pulmonares eleva a pressão pulmonar e provoca hipertensão arterial pulmonar (HAP). A HAP resulta em aumento da pós-carga do ventrículo direito (VD), causando hipertrofia ventricular e consequente insuficiência cardíaca. Não existe um tratamento específico para o remodelamento desadaptativo do VD secundário à HAP. Objetivos Este estudo tem como objetivo explorar duas abordagens terapêuticas, o suco de uva (SU) e os hormônios tireoidianos (HT), no tratamento do estresse oxidativo induzido pela HAP e nas alterações funcionais cardíacas. Métodos Parâmetros ecocardiográficos relacionados à resistência dos vasos pulmonares (relação TA/TE), contratilidade do VD (ESPAT) e função diastólica do VD (relação dos picos E/A) foram avaliados. Além disso, foram medidos ROS totais, peroxidação lipídica, enzimas antioxidantes, proteínas de manipulação de cálcio, expressão de proteínas pró-oxidantes e antioxidantes. Valores de p<0,05 foram considerados estatisticamente significativos. Resultados Ambos os tratamentos, com SU e HT, demonstraram uma redução na resistência pulmonar (~22%), além de melhorias na ESPAT (inotropismo ~11%) e na relação TA/TE (~26%) (p<0,05). Não houve alterações entre os grupos na relação do pico de E/A. Embora ROS e TBARS não tenham sido estatisticamente significativos, os tratamentos com SU e HT diminuíram os níveis de xantina oxidase (~49%) e normalizaram a expressão de HSP70 e proteínas de manipulação de cálcio (p<0,05). No entanto, apenas o tratamento com HT melhorou a função diastólica (~50%) e aumentou o imunoconteúdo de NRF2 (~48%) (p<0,05). Conclusões Até onde sabemos, este estudo é pioneiro ao mostrar que o HT administrado em conjunto com o SU promoveu melhorias funcionais e bioquímicas em um modelo de HAP. Além disso, nossos dados sugerem que os tratamentos com SU e HT se mostraram cardioprotetores, sejam combinados ou não, e exibiram seus benefícios ao modular o estresse oxidativo e as proteínas de manipulação do cálcio.

Abstract Background Adverse remodeling of lung vessels elevates pulmonary pressure and provokes pulmonary arterial hypertension (PAH). PAH results in increased right ventricle (RV) afterload, causing ventricular hypertrophy and the onset of heart failure. There is no specific treatment for maladaptive RV remodeling secondary to PAH. Objectives This study aims to explore two therapeutic approaches, grape juice (GJ) and thyroid hormones (TH), on PAH-induced oxidative stress and cardiac functional changes. Methods Parameters of echocardiography related to lung vessel resistance (AT/ET ratio), RV contractility (TAPSE), and RV diastolic function (E/A peaks ratio) were evaluated. Also, total ROS, lipid peroxidation, antioxidant enzymes, calcium handling proteins, pro-oxidant and antioxidant protein expression were measured. Values of p<0.05 were considered statistically significant. Results Both GJ and TH treatments demonstrated reductions in pulmonary resistance (~22%) and improvements in TAPSE (inotropism ~11%) and AT/ET ratio (~26%) (p<0.05). There were no changes amongst groups regarding the E/A peak ratio. Although ROS and TBARS were not statistically significant, GJ and TH treatments decreased xanthine oxidase (~49%) levels and normalized HSP70 and calcium handling protein expression (p<0.05). However, only TH treatment ameliorated diastolic function (~50%) and augmented NRF2 immunocontent (~48%) (p<0.05). Conclusions To the best of our knowledge, this study stands as a pioneer in showing that TH administered together with GJ promoted functional and biochemical improvements in a PAH model. Moreover, our data suggest that GJ and TH treatments were cardioprotective, combined or not, and exhibited their beneficial effects by modulating oxidative stress and calcium-handling proteins.

Neoplasia endócrina múltiple y enfermedad inflamatoria intestinal de inicio muy temprano. Una asociación inesperada / Multiple endocrine neoplasia and very early onset in flammatory bowel disease. An unexpected association

Resumen La enfermedad inflamatoria intestinal de inicio muy temprano (VEOIBD) es una entidad rara en pediatría. Es conocida su asociación con inmunodeficiencias prima rias de origen monogénico. Presentamos el caso de una paciente con diagnóstico de VEOIBD a quien se le realizó una secuenciación masiva del exoma. El resultado del estudio permitió identificar una variante patogénica en el proto oncogen RET, asociada con enfermedad neoplasia endocrina múltiple tipo 2A. No hay reportes de asociación de variantes en el proto oncogen RET con VEOIBD. No se puede adjudicar la presencia de estas dos entidades clínicas a una única causa genética.

Abstract Very early onset inflammatory bowel disease (VEOI BD) is a rare entity in pediatrics. Its association with pri mary immunodeficiencies of monogenic origin is known. We present the case of a patient diagnosed with VEOIBD who underwent massive paralleled exome sequencing. The result of the study showed a pathogenic variant in the RET proto-oncogene, associated with multiple endo crine neoplasia type 2A disease. There are no previous reports of association of RET proto-oncogene variants with VEOIBD. The presence of these two clinical entities cannot be attributed to a single genetic cause.
