RESUMEN
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?
RESUMEN
Introducción La diabetes mellitus tipo 2 es una enfermedad de alta prevalencia y está asociada a mayor morbimortalidad. Debido al bajo porcentaje de compensación, se han buscado nuevas estrategias de tratamiento farmacológico, como los inhibidores del cotransportador sodio-glucosa tipo 2. Objetivo Describir la evolución de pacientes diabéticos tipo 2 insulino-requirentes tratados con empagliflozina en el Hospital Peñaflor, ubicado en el sector poniente de la Región Metropolitana, Chile. El objetivo primario fue evaluar la eficacia del medicamento respecto a hemoglobina glicosilada A1c. Los objetivos secundarios fueron registrar el logro de hemoglobina glicosilada A1c igual o menor a 7,5% según análisis de supervivencia. Luego, consignar el cambio en la velocidad de filtración glomerular y en la excreción urinaria de albúmina post tratamiento. Métodos Revisión de ficha clínica de todos los pacientes tratados con empagliflozina desde noviembre de 2019 a junio de 2023. Media de seguimiento de 19 (de 16,3 a 40) meses. Para comparación entre valores de hemoglobina glicosilada A1c según rangos de seguimiento, se utilizó prueba T de Student de términos pareados o prueba de Wilcoxon. Resultados Se estudió a 58 pacientes, 15 hombres y 43 mujeres (74,1%). Edad 58,5 ± 9,2 años, rango de 35 a 75 años. Hemoglobina glicosilada A1c basal de 10,3 ± 1,6% y 8,98% ± 2,2 en un rango de seguimiento de 18 a 24 meses post tratamiento, resultando en un descenso de 1,27% (p = 0,002; intervalo de confianza 95%: 0,5 a 2,03). El efecto adverso más frecuente fue infección del tracto urinario. Conclusiones Los pacientes diabéticos tipo 2 insulino-requirentes tratados con empagliflozina en el Hospital Peñaflor lograron un mejor control glicémico con pocos efectos adversos.
Background Type 2 diabetes mellitus is a highly prevalent disease and is associated with increased morbidity and mortality. Due to the low percentage of adequate glycemic control, new strategies for the treatment of type 2 diabetes mellitus have been sought, including sodium-glucose cotransporter type 2 inhibitorss. Objective To describe the evolution of patients with type 2 diabetes mellitus with insulin requirements treated with empagliflozin at the Peñaflor Hospital. The primary objective was to evaluate the efficacy of the medication regarding glycosylated hemoglobin A1c (HbA1c). The secondary objectives were: 1) achievement of HbA1c equal to or less than 7.5% according to survival analysis. 2) Change in glomerular filtration rate and urinary albumin excretion post treatment. Methods Review of clinical records of all patients treated with empagliflozin from November 2019 to June 2023. Average follow-up of 19 (16.3 to 40) months. To compare HbA1c values according to follow-up ranges, the paired T test or Wilcoxon test was used. Results We included 58 patients, 15 men and 43 women (74.1%), with an average age of 58.5 ± 9.2 years, ranging from 35 to 75 years. Baseline HbA1c of 10.3 ± 1.6% and 8.98% ± 2.2 in a follow-up of 18 to 24 months post-treatment, resulted in a decrease of 1.27% (p = 0.002; confidence interval 95%: 0.5 to 2.03). The most common adverse effect was urinary tract infection. Conclusions Patients with type 2 diabetes mellitus with insulin requirements treated with empagliflozin at the Peñaflor Hospital achieved better glycemic control with few adverse effects.
RESUMEN
ABSTRACT Purpose: Statins are one of the most prescribed classes of drugs worldwide to treat hypercholesterolemia and dyslipidemia. By lowering the level of cholesterol, the use of statin could cause a reduction in testosterone levels. The objective was to evaluate whether the continued use of statins in patients with hypercholesterolemia causes a deficiency in testosterone and other sex hormones. Materials and Methods: Systematic Review with Meta-analysis, performed in Embase, Medline and Cochrane databases, until May 2023; PROSPERO CRD42021270424protocol. Selection performed by two independent authors with subsequent conference in stages. Methodology based on PRISMA statement. There were selected comparative studies, prospective cohorts (CP), randomized clinical trials (RCT) and cross-sectional studies (CSS) with comparison of testosterone levels before and after statin administration and between groups. Bias analysis were evaluated with Cochrane Tool, The Newcastle-Ottawa Scale (NOS), and using the Assess the Quality of Cross-sectional studies (AXIS) tool. Results: There were found on MedLine, Embase and Cochrane, after selected comparative studies, 10CP and 6RCT and 6CSS for the meta-analysis. In the Forrest plot with 6CSS, a correlation between patients with continuous use of statins and a reduction in total testosterone was evidenced with a statistically significant reduction of 55.02ng/dL (95%CI=[39.40,70.64],I²=91%,p<0.00001). In the analysis with 5RCT, a reduction in the mean total testosterone in patients who started continuous statin use was evidenced, with a statistical significance of 13.12ng/dL (95%CI=[1.16,25.08],I²=0%,p=0.03). Furthermore, the analysis of all prospective studies with 15 articles showed a statistically significant reduction in the mean total testosterone of 9.11 ng/dL (95%CI=[0.16,18.06],I²=37%,p=0.04). A reduction in total testosterone has been shown in most studies and in its accumulated analysis after statin use. However, this decrease was not enough to reach levels below normal. Conclusion: Statins use causes a decrease in total testosterone, not enough to cause a drop below the normal range and also determines increase in FSH levels. No differences were found in LH, Estradiol, SHBG and Free Testosterone analysis.
RESUMEN
Resumo Fundamento: Sabe-se que a rigidez aórtica (RA) aumenta em pacientes com disfunção erétil (DE). Os inibidores da enzima fosfodiesterase tipo 5 (PDE-5) são usados no tratamento da DE, e as respostas dos pacientes a esse tratamento podem variar. Objetivos: Nosso objetivo foi investigar o papel da RA na previsão da resposta de pacientes planejados para tomar inibidores da enzima PDE-5 devido à DE. Métodos: Um total de 96 pacientes do sexo masculino com DE foram incluídos no estudo. O questionário do Índice Internacional de Função Erétil (IIEF) foi utilizado para avaliar a presença e gravidade da DE e a resposta ao tratamento. A ecocardiografia transtorácica foi utilizada para avaliar RA. Resultados: Houve diferença estatisticamente significativa entre os valores de deformação aórtica e distensibilidade aórtica dos grupos de estudo (p<0,001). O escore delta IIEF apresentou alto nível de correlação positiva com a deformação aórtica (p<0,01, r=0,758) e um nível moderado de correlação positiva com a distensibilidade aórtica (p<0,01, r=0,574). Conclusão: Determinamos que em pacientes com DE, a deformação aórtica e a distensibilidade aórtica medidas de forma não invasiva por meio de ecocardiografia transtorácica são parâmetros importantes na previsão da resposta dos pacientes à terapia com inibidores da PDE-5.
Abstract Background: It is known that aortic stiffness (AS) increases in patients with erectile dysfunction (ED). Phosphodiesterase type-5 (PDE-5) enzyme inhibitors are used in the treatment of ED, and patients' responses to this treatment may vary. Objectives: We aimed to investigate the role of AS in predicting the response of patients planned to take PDE-5 enzyme inhibitors due to ED. Methods: A total of 96 male patients with ED were included in the study. The International Index of Erectile Function (IIEF) questionnaire was used to evaluate the presence and severity of ED and the response to treatment. Transthoracic echocardiography was used to evaluate AS. Results: There was a statistically significant difference between the aortic strain and aortic distensibility values of the study groups (p<0.001). The delta IIEF score had a high level of positive correlation with aortic strain (p<0.01, r=0.758) and a moderate level of positive correlation with aortic distensibility (p<0.01, r=0.574). Conclusion: We determined that in patients with ED, aortic strain and aortic distensibility measured non-invasively using transthoracic echocardiography are important parameters in predicting patients' response to PDE-5 inhibitor therapy.
RESUMEN
Resumo Fundamento: A doença por coronavírus 2019 (COVID-19) está associada à hipercoagulabilidade. Permanece incerto se a anticoagulação contínua para fibrilação atrial (FA) em pacientes que posteriormente contraem COVID-19 melhora os desfechos clínicos. Objetivos: Comparar a anticoagulação oral crônica com ausência de anticoagulação prévia em pacientes com FA que contraíram uma infecção por COVID-19 em relação aos desfechos de mortalidade por todas as causas, mortalidade por COVID-19, admissão em unidade de terapia intensiva (UTI) e hospitalização. Métodos: Buscamos sistematicamente no PubMed, Embase e Cochrane Library estudos elegíveis desde o início até dezembro de 2022. Incluímos estudos que compararam desfechos de COVID-19 em pacientes com e sem anticoagulação crônica prévia para FA. Foram agrupadas razões de risco (RR) com intervalos de confiança (IC) de 95% por meio de um modelo de efeitos aleatórios. O nível de significância foi estabelecido em p < 0,05. As avaliações da qualidade e do risco de viés foram realizadas de acordo com as recomendações da Cochrane. Resultados: Foram identificados 10 estudos abrangendo 1.177.858 pacientes com COVID-19 e FA, dos quais 893.772 (75,9%) estavam em anticoagulação crônica prévia para FA. Em pacientes com COVID-19, a anticoagulação crônica para FA reduziu significativamente a mortalidade por todas as causas (RR 0,75; IC 95% 0,57 a 0,99; p = 0,048; I2 = 89%) e a mortalidade relacionada à COVID-19 (RR 0,76; IC 95% 0,72 a 0,79; p < 0,001; I2 = 0%) quando comparada com a ausência de anticoagulação prévia. Em contrapartida, não houve diferença entre os grupos em relação à hospitalização (RR 1,08; IC 95% 0,82 a 1,41; p = 0,587; I2 = 95%) ou internação em UTI (RR 0,86; IC 95% 0,68 a 1,09; p = 0,216; I2 = 69%). Conclusões: Nesta metanálise, a anticoagulação crônica para pacientes com FA que contraíram COVID-19 foi associada a taxas significativamente mais baixas de mortalidade por todas as causas e mortalidade relacionada à COVID-19 em comparação com a ausência de anticoagulação anterior.
Abstract Background: Coronavirus disease 2019 (COVID-19) is associated with hypercoagulability. It remains uncertain whether ongoing anticoagulation for atrial fibrillation (AF) in patients who later contract COVID-19 improves clinical outcomes. Objectives: To compare chronic oral anticoagulation with no previous anticoagulation in patients with AF who contracted a COVID-19 infection concerning the outcomes of all-cause mortality, COVID-19 mortality, intensive care unit (ICU) admission, and hospitalization. Methods: We systematically searched PubMed, Embase, and Cochrane Library for eligible studies from inception to December 2022. We included studies comparing COVID-19 outcomes in patients with versus without prior chronic anticoagulation for AF. Risk ratios (RR) with 95% confidence intervals (CI) were pooled with a random-effects model. The level of significance was set at p < 0.05. Quality assessment and risk of bias were performed according to Cochrane recommendations. Results: Ten studies comprising 1,177,858 patients with COVID-19 and AF were identified, of whom 893,772 (75.9%) were on prior chronic anticoagulation for AF. In patients with COVID-19, being on chronic anticoagulation for AF significantly reduced all-cause mortality (RR 0.75; 95% CI 0.57 to 0.99; p = 0.048; I2 = 89%) and COVID-19-related mortality (RR 0.76; 95% CI 0.72 to 0.79; p < 0.001; I2 = 0%) when compared with no prior anticoagulation. In contrast, there was no difference between groups regarding hospitalization (RR 1.08; 95% CI 0.82 to 1.41; p = 0.587; I2 = 95%) or ICU admission (RR 0.86; 95% CI 0.68 to 1.09; p = 0.216; I2 = 69%). Conclusions: In this meta-analysis, chronic anticoagulation for patients with AF who contracted COVID-19 was associated with significantly lower rates of all-cause mortality and COVID-19-related mortality as compared with no previous anticoagulation.

RESUMEN
Abstract Background The HLA-DRB1 shared epitope (SE) is a risk factor for the development of rheumatoid arthritis (RA) and the production of anti-citrullinated protein antibodies (ACPAs) in RA patients. Our objective was to examine the real-world effectiveness of abatacept versus tumor necrosis factor inhibitors (TNFi) in patients with RA who were SE and anti-cyclic citrullinated peptide antibody (anti-CCP3) positive. Methods Abatacept or TNFi initiators who were SE + and anti-CCP3+ (> 20 U/mL) at or prior to treatment and had moderate or high CDAI score (> 10) at initiation were identified. The primary outcome was mean change in CDAI score over six months. Analyses were conducted in propensity score (PS)-trimmed and -matched populations overall and a biologic-experienced subgroup. Mixed-effects models were used. Results In the overall PS-trimmed (abatacept, n = 170; TNFi, n = 157) and PS-matched cohorts (abatacept, n = 111; TNFi, n = 111), there were numerically greater improvements in mean change in CDAI between abatacept and TNFi but were not statistically significant. Similar trends were seen for biologic-experienced patients, except that statistical significance was reached for mean change in CDAI in the PS-trimmed cohort (abatacept, 12.22 [95% confidence interval (95%CI) 10.13 to 14.31]; TNFi, 9.28 [95%CI 7.08 to 11.48]; p = 0.045). Conclusion In this real world cohort, there were numerical improvements in efficacy outcomes with abatacept over TNFi in patients with RA who were SE + and ACPA+, similar to results from a clinical trial population The only statistically significant finding after adjusting for covariates was greater improvement in CDAI with abatacept versus TNFi in the bio-experienced PS-trimmed cohort. .
RESUMEN
ABSTRACT Purpose: To report the clinical findings, treatments, and outcomes in a series of patients with vitreous metastasis from cutaneous melanoma. Methods: This single-center, retrospective, interventional case series included patients with biopsy-confirmed vitreous metastasis from cutaneous melanoma diagnosed between 1997 and 2020. Standard 23- or 25-gauge pars plana vitrectomy was performed for diagnostic sampling. Sclerotomies were treated with double or triple freeze-thaw cryotherapy. Perioperative intravitreal injections of melphalan (32 µg/0.075 mL) were administered, when indicated. Visual acuity, intraocular pressure, and systemic and ocular treatment responses were reported. Results: Five eyes of five patients with unilateral vitreous metastasis from cutaneous melanoma were identified. The median age at diagnosis was 84 (range, 37-88) years. The median follow-up after ophthalmic diagnosis was 28 (8.5-36) months; one patient did not have a follow-up. The initial visual acuity ranged from 20/30 to hand motions. Baseline clinical findings included pigmented or non-pigmented cellular infiltration of the vitreous (5/5), anterior segment (4/5), and retina (3/5). Four patients had secondary glaucoma. Systemic therapy included checkpoint inhibitor immunotherapy (n=3, all with partial/complete response), systemic chemotherapy (n=2), surgical resection (n=3), and radiation (n=2). The median time from primary diagnosis to vitreous metastasis was 2 (2-15) years. One patient had an active systemic disease at the time of vitreous metastasis. The final visual acuity ranged from 20/40 to no light perception. Ophthalmic treatment included vitrectomy in all five patients, intravitreal administration of melphalan in three, and intravitreal administration of methotrexate in one. One patient required enucleation, and histopathology revealed extensive invasion by melanoma cells. Conclusions: Vitreous metastasis from cutaneous melanoma can present as a diffuse infiltration of pigmented or non-pigmented cells into the vitreous and may be misdiagnosed as uveitis. Diagnostic pars plana vitrectomy and periodic intravitreal chemotherapy may be indicated.
RESUMO Objetivo: Descrever os achados clínicos, tratamentos, e desfechos em uma série de pacientes com me tástases vítreas de melanoma cutâneo. Métodos: Série retrospectiva de casos de único centro com intervenção. Pacientes incluídos tiveram seu diagnóstico de MVMC confirmado por biópsia entre 1997 e 2020. Vitrectomia via pars plana com 23 ou 25 gauge foram realizadas para obter espécimens. Esclerotomias foram tratadas com crioterapia em duplo ou triplo congelamento. Injeção intravítrea perioperatória de melfalano (32 ug/0,075 mL) foi administrada quando necessário. Foram relatados acuidade visual, pressão intraocular, resposta terapêutica sistêmica e ocular. Resultados: Cinco olhos de 5 pacientes com metástases vítreas de melanoma cutâneo unilateral foram identificados. Idade média de diagnóstico foi 84 anos (variando de 37-88). Seguimento médio após diagnóstico oftalmológico foi 28 (8,5-36) meses; 1 paciente não teve acompanhamento. Acuidade visual inicial variou de 20/30 a movimentos de mão. Achados clínicos iniciais incluíram infiltração de células pigmentadas e não-pigmentadas no vítreo (5/5), segmento anterior (4/5), e retina (3/5). Quatro pacientes tiveram glaucoma secundário. Tratamento sistêmico incluiu imunoterapia com inibidores da via de sinalização (3 - todos com resposta parcial/completa), quimioterapia sistêmica (2), ressecção cirúrgica (3), e irradiação (2). Intervalo médio entre diagnóstico primário e metástases vítreas foi 2 (2-15) anos. Um paciente teve doença sistêmica ativa simultânea as metástases vítreas. Acuidade visual final variou entre 20/40 e SPL. Tratamento oftalmológico incluiu vitrectomia nos 5 pacientes, melfalano intravítreo em 3 e metotrexato intravítreo em 1. Um paciente precisou de enucleação. A histopatologia revelou invasão celular extensa de melanoma. Conclusões: Metástases vítreas de melanoma cutâneo pode se manifestar como uma infiltração difusa de células pigmentadas e não-pigmentadas no vítreo e erroneamente diagnosticada como uveites. Vitrectomia diagnóstica e quimioterapia intravítrea periódica podem estar indicadas.
RESUMEN
ABSTRACT Purpose: Intravitreal antiangiogenic therapy is currently the most invasive ophthalmic procedure performed worldwide. This study aimed to describe the clinical and epidemiological profile of patients undergoing intravitreal antiangiogenic therapy in a tertiary referral hospital in Brazil. Methods: This cross-sectional, retrospective, and observational study analyzed medical records of patients who received intravitreal injections of antiangiogenic agents for the treatment of retinal diseases at the ophthalmology outpatient clinic in the Hospital das Clínicas at Unicamp between January and December 2020. Results: The study included 429 patients and 514 eyes. The study population was predominantly male (51.28%), white (80.89%), between 50 and 80 years old (mean age, 60.92 years), had complete or incomplete first-grade education (56.88%), and did not belong to the Regional Health Department of which Campinas is a part (78.55%). Bevacizumab was the most commonly used intravitreal injectable medicine (79.38%), pro re nata was the most commonly used treatment regimen (90.27%), and macular edema was the most prevalent pathology indicative of treatment (60.12%), with diabetes etiology accounting for 48.25%. The average number of injections per patient was 3.83, with the macular neovascularization group and the pro re nata group having the highest and lowest with five and three injections, respectively. Treatment adherence was associated with the patient's pathology, and the macular edema (52.24%) and macular neovascularization (49.48%) groups had the lowest adherence rates. Conclusions: This study evaluated the epidemiological and clinical profile of patients undergoing antiangiogenic therapy in a high-complexity public hospital, which is fundamental for a better understanding of the demand for ophthalmic reference service in Brazil, and the analysis of functional results and user adherence profile promotes optimization of indications and leverages the benefits of intravitreal therapy.

O fármaco mais utilizado nas injeções intravítreas foi o bevacizumabe (79,38%), o principal regime de tratamento foi o pro re nata (90,27%) e a principal grupo de patologia indicativa de tratamento foi o edema macular (60,12%), sendo 48,25% desses de etiologia diabética. A média de injeções foi de 3,83/paciente, sendo o grupo de neovascularização macular o de maior mediana com 5 injeções/paciente e o esquema pro re nata o regime de tratamento com menor mediana, 3 injeções/paciente. A adesão ao tratamento associou-se a patologia do paciente, sendo as menores taxas de adesão as dos grupos com edema macular (52,24%) e neovascularização macular (49,48%). Conclusões: O presente estudo avaliou o perfil epidemiológico e clínico dos pacientes submetidos a terapia antiangiogênica em hospital público de alta complexidade, o que é fundamental para melhor conhecimento da demanda de serviço oftalmológico de referência no Brasil e possibilita, a partir da análise dos resultados funcionais e perfil de adesão dos usuários, otimizar as indicações e alavancar os benefícios de terapia intravítrea.
RESUMEN
ABSTRACT Purpose: To evaluate early changes after the first antivascular endothelial growth factor injection for macular edema secondary to diabetic retinopathy and retinal vein occlusion and the relationship between longterm outcomes. Methods: The study enrolled patients who received anti-vascular endothelial growth factor injections for treatment-naive macular edema due to retinal vein occlusion and diabetic retinopathy. The central macular thickness was measured at baseline, post-injection day 1, week 2, and month 1, and at the last visit using spectral-domain optical coherence tomography. A good response was defined as a central macular thickness reduction of ≥10% on post-injection day 1. Patients were reassessed at the last visit with regard to treatment response on post-injection day 1 based on the favorable anatomic outcome defined as a central macular thickness <350 µm. Results: In total, 26 (44.8%) patients had macular edema-retinal vein occlusion and 32 (55.2%) had macular edema-diabetic retinopathy. The mean follow-up time was 24.0 (SD 8.5) months. A statistically significant decrease in the central macular thickness was observed in both patients with macular edema-retinal vein occlusion and macular edema-diabetic retinopathy after antivascular endothelial growth factor injection therapy (p<0.001 for both). All patients with macular edema-retinal vein occlusion were good responders at post-injection day 1. All nongood responders at post-injection day 1 belong to the macular edema-diabetic retinopathy group (n=16.50%). The rate of hyperreflective spots was higher in nongood responders than in good responders of the macular edema-diabetic retinopathy group (p=0.03). Of 42 (2.4%) total good responders, one had a central macular thickness >350 µm, whereas 5 (31.2%) of 16 total nongood responders had a central macular thickness >350 µm at the last visit (p=0.003). Conclusion: The longterm anatomical outcomes of macular edema secondary to retinal vein occlusion and diabetic retinopathy may be predicted by treatment response 1 day after antivascular endothelial growth factor injection.
RESUMO Objetivo: Avaliar as alterações precoces após a primeira injeção de anticorpos antifator de crescimento endotelial vascular (anti-VEGF) em casos de edema macular secundário à retinopatia diabética e oclusão da veia da retina e a relação entre essas alterações e o resultado a longo prazo. Métodos: Foram incluídos no estudo pacientes que receberam uma injeção de antifator de crescimento endotelial vascular para edema macular, virgem de tratamento e devido à oclusão da veia retiniana ou a retinopatia diabética. A espessura macular central foi medida no início do tratamento e no 1º dia, 2ª semana e 1º mês após a injeção, bem como na última visita, através de tomografia de coerência óptica de domínio espectral. Definiu-se uma "boa resposta" como uma redução ≥10% na espessura macular central no 1º dia após a injeção. Os pacientes foram reavaliados na última visita com relação à resposta ao tratamento no 1º dia após a injeção, com base em um resultado anatômico favorável, definido como uma espessura macular central <350 µm. Resultado: Foram registrados 26 (44,8%) pacientes com edema macular e oclusão da veia da retina e 32 (55,2%) com edema macular e retinopatia diabética. O tempo médio de acompanhamento foi de 24,0 meses (desvio-padrão de 8,5 meses). Foi observada uma diminuição estatisticamente significativa da espessura macular central após o tratamento antifator de crescimento endotelial vascular tanto em pacientes com edema macular e oclusão da veia retiniana quanto naqueles com edema macular e retinopatia diabética (p<0,001 para ambos). Todos os pacientes com edema macular e oclusão da veia retiniana responderam bem no 1º dia pós-injeção. Todos os que responderam mal no 1º dia pós-injeção pertenciam ao grupo com edema macular e retinopatia diabética (n=16,50%). A presença de manchas hiperrefletivas foi maior nos pacientes que responderam mal do que naqueles que tiveram boa resposta no grupo com edema macular e retinopatia diabética (p=0,03). Um dos 42 (2,4%) pacientes com boa resposta total teve espessura macular central >350 um, enquanto 5 (31,2%) do total de 16 pacientes com resposta ruim apresentaram espessura macular central >350 µm na última visita (p=0,003). Conclusão: O resultado anatômico de longo prazo do edema macular secundário à oclusão da veia retiniana e à retinopatia diabética pode ser previsto pela resposta ao tratamento no 1º dia após a injeção de antifator de crescimento endotelial vascular.
RESUMEN
ABSTRACT Background: Proton pump inhibitors (PPIs) are widely prescribed worldwide, often resulting in their overuse. Consequently, it is essential to identify the likely causes of this overuse to facilitate their appropriate prescription. Objective: This study aims to assess physician prescribing patterns, their knowledge of PPIs, and factors affecting their knowledge. Methods: An online survey was conducted among Latin American and Spanish physicians, collecting the following data: professional information, patterns of PPI usage, familiarity with published evidence, and the management approach in three hypothetical case-scenarios. Participant knowledge was categorized as sufficient or insufficient based on the results of the case scenarios. Subsequently, subgroup analysis was performed based on physician training level, years in practice, specialty, and time since the last PPI literature review. Results: A total of 371 physicians participated in the survey. Thirty-eight percent frequently prescribe PPIs, primarily for prophylactic purposes (57.9%). Eighty percent were unfamiliar with PPI deprescribing strategies, and 54.4% rarely reviewed the ongoing indication of patients taking a PPI. Sixty-four percent demonstrated sufficient knowledge in the case-scenarios. A significant association was observed between specialty type (medical vs surgical: 69.4% vs 46.8%, P<0.001), the timing of the PPI indication literature review (<5 years vs >5 years: 71.4% vs 58.7%, P=0.010), and sufficient knowledge. Conclusion: While most participants prescribed PPIs regularly and for prophylaxis purposes, the majority were unfamiliar with deprescribing strategies and rarely reviewed ongoing indications. Sufficient knowledge is correlated with recent literature reviews and medical specialty affiliation.
RESUMO Contexto: Os inibidores da bomba de prótons (IBPs) são amplamente prescritos em todo o mundo, muitas vezes resultando em seu uso excessivo. Consequentemente, é essencial identificar as prováveis causas desse uso excessivo para facilitar sua prescrição adequada. Objetivo: Este estudo tem como objetivo avaliar o padrão de prescrição dos médicos, seu conhecimento sobre IBPs e fatores que afetam seu conhecimento. Métodos: Uma pesquisa on-line foi conduzida entre médicos latino-americanos e espanhóis, coletando os seguintes dados: informações profissionais, padrões de uso de IBP, familiaridade com evidências publicadas e abordagem de manejo em três casos-cenários hipotéticos. O conhecimento dos participantes foi categorizado em suficiente ou insuficiente com base nos resultados dos cenários de caso. Posteriormente, a análise de subgrupos foi realizada com base no nível de formação do médico, anos de prática, especialidade e tempo desde a última revisão da literatura dos IBPs. Resultados: Um total de 371 médicos participaram da pesquisa. Trinta e oito por cento prescrevem frequentemente IBP, principalmente para fins profiláticos (57,9%). Oitenta por cento não estavam familiarizados com as estratégias de prescrição de IBP, e 54,4% raramente revisaram a indicação contínua de pacientes em uso de IBP. Sessenta e quatro por cento demonstraram conhecimento suficiente nos cenários-caso. Observou-se associação significativa entre o tipo de especialidade (médica vs cirúrgica: 69,4% vs 46,8%, P<0,001), o momento da revisão da literatura de indicação do IBP (<5 anos vs >5 anos: 71,4% vs 58,7%, P=0,010) e conhecimento suficiente. Conclusão: Embora a maioria dos participantes prescrevesse IBPs regularmente e para fins de profilaxia, no entanto, não estava familiarizada com estratégias de prescrição e raramente revisava as indicações em andamento. O conhecimento suficiente está correlacionado com revisões recentes da literatura e afiliação à especialidade médica.
RESUMEN
ABSTRACT Introduction Instruments to manage adverse effects of endocrine therapy with Aromatase inhibitors (AI) may improve adherence and persistence to treatment and Health-Related Quality of Life (HRQL). The 31-item Cervantes Scale (CS-31) is an HRQL questionnaire with particularities of the perimenopausal and postmenopausal period that could be an appropriate instrument to assess HRQL in Breast Cancer (BC) survivors. Objective This study aimed to perform additional validation of the CS-31 for BC survivors undergoing adjuvant endocrine therapy. Methods This prospective study was performed at three time points named T0, T1, and T2: initial, intermediate, and final follow-up period, respectively, totaling 24 months of follow-up. At each time point, the participants completed the CS-31, Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), and Hospital Anxiety and Depression Scale (HADS). The internal consistency, construct validity, responsiveness analyses, and known-group validity of CS-31 were evaluated. Results This study included 89 postmenopausal women diagnosed with hormone receptor-positive early BC in adjuvant endocrine therapy with AI. The internal consistency was good (Cronbach's alpha = 0.89). Construct validity received a positive rating, with 100% of results consistent with prior hypotheses. A prospective improvement in HRQL was identified for the CS-31 Global Score and FACIT-F Total Score and for most of their domains. Furthermore, women with anxiety and depression by HADS presented worse HRQL by CS-31. Conclusion The authors identified that the CS-31 seems to be appropriate for use in oncology medical routine and may help to monitor adverse effects and HRQL of BC survivors during adjuvant endocrine therapy.
RESUMEN
Abstract PD-1 (programmed Death-1) immune checkpoint inhibitors have provided significant benefits to tumor patients. However, a considerable proportion of the patients develop immune-related adverse events (irAEs), of which cutaneous irAEs (cirAEs, e.g., psoriasis) occur relatively early. This review provides an overview of the current progress in psoriasis de novo or exacerbation by PD-1 checkpoint inhibitors. It not only describes the relevant influencing factors but also theoretically analyzes the immunological mechanisms that lead to the onset or exacerbation of psoriasis. Finally, the authors present guidelines for the treatment of psoriasis de novo or exacerbation by PD-1 checkpoint inhibitors. The review is intended to assist dermatologists in the early recognition and effective individualized management of such cirAE, which is helpful to continue or adjust the tumor-targeted immunotherapy on the basis of ensuring the quality of life of tumor patients.
RESUMEN
Resumen Los inhibidores de puntos de control inmune (ICIs) son anticuerpos monoclonales cada vez más utilizados en tratamientos oncológicos. A medida que aumenta la experiencia en el uso de inmunoterapia, se conoce cada vez más su perfil de seguridad y los efectos adversos inmunomediados. Entre ellos se encuentra la cetoaci dosis diabética (CAD), complicación infrecuente, grave y potencialmente mortal. En este trabajo describimos los casos de tres pacientes que se presentaron con episo dios de CAD durante el tratamiento con ICIs, dos de los cuales manifestaron con formas fulminantes, llevando un curso agudo con valores de hemoglobina glicosilada inicialmente normales. Asimismo, realizamos una revi sión de la literatura sobre la CAD asociada a ICIs a fines de resaltar la importancia de advertir estas complica ciones potencialmente fatales e instaurar rápidamente la terapéutica apropiada.
Abstract Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that are increasingly used in cancer treat ments. As experience in the use of immunotherapy increases, more is known about its safety profile and immune-mediated adverse effects. Among them is dia betic ketoacidosis (DKA), a rare but serious fatal compli cation of treatment. In this paper we describe the cases of three patients who presented with episodes of DKA during treatment with ICIs, two of which manifested with fulminant forms, leading to an acute course with initially normal glycosylated hemoglobin values. In ad dition, we conducted a review of the literature on DKA associated with ICIs in order to highlight the importance of noticing these potentially fatal complications and promptly establishing appropriate therapy.

RESUMEN
ABSTRACT BACKGROUND: Until recently, the treatment of people with hemophilia A and inhibitors (PwHAi) was based on the use of bypassing agents (BPA). However, the advent of emicizumab as prophylaxis has demonstrated promising results. OBJECTIVES: We aimed to compare the bleeding endpoints between PwHAi on BPA and those on emicizumab prophylaxis. DESIGN AND SETTING: Systematic review of interventions and meta-analysis conducted at the Universidade Federal de Goiás, Goiânia, Goiás, Brazil. METHODS: The CENTRAL, MEDLINE, Scopus, and LILACS databases were searched on February 21, 2023. Two authors conducted the literature search, publication selection, and data extraction. The selected publications evaluated the bleeding endpoints between PwHAi on emicizumab prophylaxis and those on BPA prophylaxis. The risk of bias was evaluated according to the Joanna Briggs Institute criteria. A meta-analysis was performed to determine the annualized bleeding rate (ABR) for treated bleeds. RESULTS: Five publications (56 PwHAi) were selected from the 543 retrieved records. Overall, bleeding endpoints were lower during emicizumab prophylaxis than during BPA prophylaxis. All the publications had at least one risk of bias. The only common parameter for the meta-analysis was the ABR for treated bleeds. During emicizumab prophylaxis, the ABR for treated bleeds was lower than during BPA prophylaxis (standard mean difference: −1.58; 95% confidence interval −2.50, −0.66, P = 0.0008; I2 = 68.4%, P = 0.0031). CONCLUSION: Emicizumab was superior to BPA in bleeding prophylaxis in PwHAi. However, both the small population size and potential risk of bias should be considered when evaluating these results.

RESUMEN
OBJECTIVE To systematically review the pharmacoeconomic evaluation literature about proprotein convertase subtilisin/kexin type 9 （PCSK9） inhibitors for the prevention of cardiovascular disease in patients with hypercholesterolemia， and to provide a reference for clinical treatment， health decision-making and future follow-up research. METHODS Retrieved from English and Chinese databases such as PubMed and CNKI， the pharmacoeconomic literature about PCSK9 inhibitors （evolocumab and alirocumab） for the prevention of cardiovascular disease in patients with hypercholesterolemia was collected from the establishment of the database to October 8， 2023. The quality of the included literature was assessed with Consolidated Health Economic Evaluation Reporting Standards 2022 （CHEERS 2022） scale. The descriptive analysis was performed for basic information， model structure， related parameters， sensitivity analysis and the results of included studies. RESULTS & CONCLUSIONS A total of 29 literature were included， with overall good quality. The evaluation mainly adopted the Markov model from the healthcare system， payer and societal perspective. The effectiveness and utility data mainly came from the previous studies； the direct cost was mainly considered with a discount rate of 1.5%-5.0% per year， while the willingness-to-pay threshold was often set at 1-3 times the gross domestic product per capita. Most health output indicators were measured in life years and quality-adjusted life years. The sensitivity analysis of most studies demonstrated the robustness and the main influential factor was the drug cost. Most Chinese studies showed that PCSK9 inhibitor was not cost-effective for the prevention of cardiovascular disease in patients with acute coronary syndrome， myocardial infarction and atherosclerotic cardiovascular disease. It was cost-effective to use PCSK9 inhibitors for the prevention of cardiovascular disease only in specific groups， such as patients with triple vessel disease， patients with newly diagnosed acute coronary syndrome and low-density lipoprotein cholesterol≥100 mg/dL. Future research should refer to the CHEERS 2022 scale to improve the design， and strive to select large-scale， high-quality data to enhance the quality of reports and the transparency of health decisions， so as to more accurately assess the cost-effectiveness of PCSK9 inhibitors.
RESUMEN
The FMS-like tyrosine kinase 3 (FLT3) gene mutation is the most common genetic mutation in acute myeloid leukemia (AML) and is associated with poor prognosis. Various targeted inhibitors have been developed for FLT3 mutations and have shown promising clinical efficacy. However, the emergence of resistance poses new challenges for targeted therapy in AML. This article provides an overview of the pathological and prognostic role of FLT3 mutations in AML, the current research progress on commonly used FLT3 inhibitors (type I and type II), the mechanisms of FLT3 inhibitor resistance, and strategies for overcoming resistance.
RESUMEN
Receptor-interacting serine/threonine-protein kinase 3(RIPK3),a member of the RIP kinase family,plays an important role in cell death,especially in necroptosis. In addition,RIPK3 is also involved in apoptosis and pyroptosis,suggesting that RIPK3 may be the intersection of multiple cell death and it possesses the potential to be a target for precise regulation of cell death. According to the kinase binding mode,current RIPK3 inhibitors can be classified into type ,type Ⅱ and other types. This review summarizes the research progress in the role of RIPK3 in cell death and its inhibitors,which is of great significance in seeking drugs for the treatment of injury-related diseases.
