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?

Bastidores da prescrição de inibidores de bomba de prótons: uma pesquisa internacional sobre práticas e conhecimentos médicos / Behind the proton pump inhibitor prescription: an international survey on physician practices and knowledge

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.

Health-Related quality of life by 31-item Cervantes scale in breast cancer survivors undergoing adjuvant endocrine therapy

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.

Is there a relationship between the first-day results of anti-VEGF therapy for macular edema due to vascular diseases and longterm outcomes? / Há alguma relação entre os resultados do primeiro dia de terapia anti-VEGF para edema macular devido a doenças vasculares e o resultado a longo prazo?

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.

Vitreous metastasis from cutaneous melanoma: diagnosis and management / Metástase vítrea de melanoma cutâneo: diagnóstico e tratamento

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.

Profile of patients treated with intravitreal antiangiogenics in a Brazilian public service with high level of complexity / Perfil de pacientes tratados com antiangiogênicos intravítreo em serviço público brasileiro de alto nível de complexidade

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.

Comparative effectiveness of abatacept versus TNF inhibitors in rheumatoid arthritis patients who are ACPA and shared epitope positive

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. .

Is it Always Laryngopharyngeal Reflux? How Voice Disorders Can Manifest as LPR

Introduction: Laryngopharyngeal reflux (LPR) manifests with a constellation of common throat symptoms and inconclusive signs on laryngoscopic exam. It is a diagnosis, often made clinically, that can lead to prescriptions of proton pump inhibitors that are unnecessary and potentially harmful. Glottic insufficiency (GI) and the accompanying hyperfunctional laryngeal behaviors can also present with similar, common throat complaints that may or may not include a qualitative change to the voice. Methods: This is a reflection article. It is written to summarize, explain, and support with evidence the opinion of the author on the topic of how symptoms of voice disorders can easily be mistaken for symptoms of LPR. The offered reflection is based on his experience, research and the available literature. Reflection: This article intends to explore the similarities between GI and LPR, how to ultimately differentiate them and how to approach treatment with a broader differential diagnosis. Conclusion: LPR and GI can present with identical, vague throat, and voice symptoms. Empiric medication trials, behavioral interventions and objective laryngovideostroboscopy, impedance-based reflux, and esophageal motility testing may all be needed, sometimes in a trial and error fashion, to correctly diagnose and treat a patient's symptoms.

Introducción: El reflujo laríngeo-faríngeo (LPR, por sus siglas en inglés) se manifiesta con una serie de síntomas comunes en la garganta y signos no concluyentes en el examen larinoscópico. Es un diagnóstico que a menudo se realiza clínicamente y que puede llevar a la prescripción de inhibidores de la bomba de protones que son innecesarios y potencialmente perjudiciales. La insuficiencia glótica (IG) y los comportamientos laríngeos hiperfuncionales que la acompañan también pueden presentar síntomas de garganta comunes similares, que pueden o no incluir un cambio cualitativo en la voz. Métodos: Este es un artículo de reflexión. Está escrito para resumir, explicar y respaldar con evidencia la opinión del autor sobre cómo los síntomas de los trastornos de la voz pueden confundirse fácilmente con los síntomas del LPR. La reflexión ofrecida se basa en su experiencia, investigación y la literatura disponible. Reflexión: Este artículo tiene la intención de explorar las similitudes entre la IG y el LPR, cómo diferenciarlos finalmente y cómo abordar el tratamiento con un diagnóstico diferencial más amplio. Conclusión: El LPR y la IG pueden presentar síntomas idénticos y vagos en la garganta y la voz. Puede ser necesario realizar ensayos de medicación empírica, intervenciones conductuales y pruebas objetivas de laringovideostroboscopia, reflujo basado en impedancia y motilidad esofágica, a veces de manera experimental, para diagnosticar y tratar correctamente los síntomas de un paciente.

Niveles de colinesterasa sérica en agricultores de San Pablo de Borbur, Boyacá, expuestos a organofosforados

Introducción: Las colinesterasas son enzimas que se encargan de hidrolizar la acetilcolina en ácido acético y colina, poniéndole fin a la transmisión nerviosa a lo largo de la sinapsis de las uniones neuromusculares. La medición de la actividad de la colinesterasa sérica constituye un indicador del efecto causado por la exposición prolongada a los organofosforados. Objetivo: Determinar los niveles de colinesterasa sérica y factores relacionados con la exposición a organofosforados en agricultores de la vereda de Páramo Lagunas de San Pablo de Borbur, Boyacá, Colombia. Metodología: Estudio prospectivo, de corte transversal, con una muestra de 57 trabajadores. A cada individuo se le aplicó una encuesta de datos sociodemográficos y factores laborales, posteriormente se les tomó una muestra de sangre venosa en ayuno de 8-12 horas; con el fin de determinar las concentraciones de colinesterasa sérica (kit Colinesterasa Butiriltiocolina Biosystems®) con el equipo automatizado de química clínica A-15 de Biosystems®. Resultados: El rango de edad de los participantes estuvo entre los 22 y 64 aflos, el 72 % de los individuos pertenecía al sexo masculino. El 3,5 % (2 varones) presentó valores inferiores al intervalo biológico de referencia (IBR), el 88 % de las personas afirmó realizar tareas con plaguicidas y el 54 % afirmó no utilizar los elementos de protección personal (EPP) al trabajar con estas sustancias. Conclusiones: Se evidenció la falta de escolaridad y la ausencia del acompaflamiento técnico en esta zona, lo que induce a que estos agricultores realicen procesos agrícolas relacionados con la aplicación de plaguicidas sin el adecuado conocimiento y sin la utilización adecuada de EPP.

Introduction: Cholinesterases are enzymes responsible for hydrolyzing acetylcholine in acetic acid and choline, which ends nerve transmission along the synapse of neuromuscular junctions. Measurement of serum cholinesterase activity acts as an indicator of the effect caused by prolonged exposure to organophosphates and carbamates Objective: To determine serum cholinesterase levels and factors related to exposure to organophosphates in farmers from the county of Páramo Lagunas in San Pablo de Borbur, Boyacá, Colombia. Methodology: Prospective, cross-sectional study, with a sample of 57 agricultural workers, a survey of sociodemographic data and labor factors was applied to each individual and a venous blood sample was taken in an 8-12 hour fasting, Serum cholinesterase concentrations were determined (Biosystems® Butyrylthiocholine Cholinesterase kit), by means of the Biosystems® A-15 automated clinical chemistry kit. Results: The age range of the participants was between 22 and 64 years old, 72% of the individuals belonged to the male sex. 3.5% (2 male individuals) presented values lower than the biological reference interval (BRI); 88% of the people affirmed to carry out tasks with pesticides and 54% of them affirmed not to use personal protective equipment (PPE) when working with these substances. Conclusions: The lack of schooling was evidenced in most of the farmers, as well as the absence of technical support to this area, which induces these farmers to carry out agricultural processes such as pesticide application, without adequate knowledge and without the proper use of PPE.

Avoidant restrictive eating disorder and panic attacks in an adult man: A case report / Trastorno evitativo restrictivo de la ingesta alimentaria y ataques de pánico en un hombre adulto: Reporte de caso

Abstract Avoidant or Restrictive Food Intake Disorder (ARFID) is an eating disorder (ED) not common in adults. In this article we present a clinical case of ARFID in a 37-year-old male patient treated in an ED center in Medellin, Colombia; displaying anxious symptoms that began a year earlier and concomitant weight loss, following a traumatic event causing an overall impairment with that patient. Several medical evaluations/examinations looking for organic causes, were excluded. Interventions were implemented by a psychiatry, a psychotherapist using cognitive-behavior therapy (CBT), and a nutritionist, all in face-to-face modality, which were carried out weekly for the first three months, then biweekly and subsequently quarterly. each lasting approximately 40-60 minutes. After the set of pharmacological interventions and psychotherapy, a great improvement in the functionality of the patient was observed. Improvement was found with respect to eating in public, food variation and panic attacks. In the absence of guidelines, it is important to use standardized and replicable treatments in this population.

Resumen El trastorno evitativo restrictivo de la ingesta (TERIA) es un trastorno alimentario (TCA) raro en adultos. Se presenta el caso de un hombre de 37 años con TERIA y trastorno de pánico atendido en un centro para TCA en Medellín, Colombia, quien presentó un año de síntomas ansiosos y pérdida de peso después de evento traumático, generando disfuncionalidad. Fue evaluada y excluida organicidad. Se realizaron intervenciones por parte de psiquiatría, psicoterapia con enfoque cognitivo conductual y nutrición, todas en modalidad presencial, las cuales se realizaron semanalmente los primeros tres meses, luego quincenalmente y posteriormente trimestralmente. Cada una con una duración de 40-60 minutos aproximadamente por sesión. Posterior al conjunto de intervenciones farmacológicas y psicoterapia, se observó una gran mejoría la funcionalidad del paciente, se encontró mejoría con respecto a comer en público, variación en los alimentos y ataques de panico. Ante la ausencia de guías de manejo de TERIA en adultos es relevante realizar tratamientos estandarizados que puedan ser replicados.

Impacto de la optimización del tratamiento hipolipemiante en el riesgo cardiovascular residual / Impact of Optimizing Lipid-Lowering Therapy on Residual Cardiovascular Risk

RESUMEN Introducción: el modelo SMART-REACH predice el riesgo de eventos cardiovasculares recurrentes. Objetivos: los objetivos de este estudio fueron: a) evaluar el riesgo residual en una población en prevención secundaria y niveles de colesterol asociado a lipoproteínas de baja densidad (C-LDL) fuera de meta; b) mediante un modelo de simulación, determinar el impacto de optimizar las terapias hipolipemiantes en términos de reducción del riesgo residual. Material y métodos: estudio transversal, descriptivo y multicéntrico. Se incluyeron consecutivamente pacientes con antecedentes cardiovasculares y un C-LDL mayor o igual que 55 mg/dL. El riesgo de eventos recurrentes (infarto agudo de miocardio, accidente cerebrovascular o muerte vascular) a 10 años y a lo largo de la vida se estimó utilizando el modelo SMART-REACH. Mediante una simulación, se optimizó el tratamiento hipolipemiante de cada paciente (utilizando estatinas, ezetimibe o inhibidores de proproteína convertasa subtilisina kexina tipo 9 [iPCSK9]), se estimó el descenso del C-LDL, se verificó el alcance del objetivo lipídico y se calculó la reducción del riesgo cardiovascular y el número necesario a tratar (NNT) correspondiente. Resultados: se incluyeron 187 pacientes (edad media 67,9 ± 9,3 años, 72,7% hombres). Los riesgos residuales calculados a 10 años y a lo largo de la vida fueron 37,1 ± 14,7% y 60,3 ± 10,7%, respectivamente. Globalmente, se pudo optimizar una sola estrategia farmacológica con estatinas, ezetimibe o un iPCSK9 en el 38,5%, el 11,5% y el 5,5% de la población, respectivamente. La optimización basada en dos tratamientos se realizó en el 27,5% (estatinas + ezetimibe), el 7,7% (estatinas + iPCSK9) y el 1,1% (ezetimibe + iPCSK9) de los casos. En 15 pacientes se optimizó el tratamiento considerando los tres fármacos. El 53,9% y el 62,9% de las acciones para optimizar el tratamiento mostraron un NNT menor que 30 para evitar un evento a 10 años o a lo largo de la vida, respectivamente. Conclusión: en este estudio, los pacientes con antecedentes cardiovasculares que no alcanzan la meta de C-LDL mostraron un riesgo residual considerable. La simulación mostró un importante margen para optimizar el tratamiento, con un impacto notable en el riesgo residual.

ABSTRACT Background: The SMART-REACH model predicts the risk or recurrent cardiovascular events. Objectives: The objectives of this study were: a) to evaluate the residual cardiovascular risk in a secondary prevention population with LDL-C levels above the recommended goal, using a simulation model; and b) to determine the impact of optimizing lipid-lowering therapies in terms of residual cardiovascular risk reduction. Methods: We conducted a cross-sectional, descriptive and multicenter study. Patient with a history of cardiovascular disease and a LDL-C ≥55 mg/dL were consecutively included. The 10-year and lifetime risk of recurrent events (myocardial infarction, stroke, or vascular death) were estimated using the SMART-REACH model. By means of a simulation, lipid-lowering treatment was optimized for each patient [using statins, ezetimibe and/or PCSK9 (PCSK9) inhibitors], with estimation of LDL-C reduction, checking if lipid-lowering goal was achieved and calculating the reduction in cardiovascular risk and the corresponding number needed to treat (NNT). Results: The cohort was made up of 187 patients; mean age was 67.9 ± 9.3 years and 72.7% were men. The calculated 10-year and lifetime residual risks were 37.1 ± 14.7% and 60.3 ± 10.7%, respectively. Overall, treatment was optimized with a single pharmacological strategy with statins, ezetimibe or PCSK9 inhibitor in 38.5%, 11.5% and 5.5% of the population, respectively. Optimization based on two treatments was performed in 27.5% (statins + ezetimibe), 7.7% (statins + PCSK9 inhibitor) and 1.1% (ezetimibe + PCSK9 inhibitor) of the cases. In 15 patients, treatment was optimized when the three drugs (statins + ezetimibe + PCSK9 inhibitor) were considered. Overall, 53.9% and 62.9% of the actions implemented to optimize treatment showed a 10-year or lifetime NNT < 30 to prevent an event, respectively. Conclusion: In this study, patients with a history of cardiovascular disease who do not reach LDL-C goal showed significant residual cardiovascular risk. The simulation model showed a significant margin for optimizing treatment, with a marked reduction in residual cardiovascular risk.

Pediatric and adolescent chronic myeloid leukemia: A follow-up study in Western India

Background: Chronic myeloid leukemia (CML) is relatively rare in pediatric and adolescent age groups. The purpose of this study was to evaluate the clinical, hematopathological, and biochemical parameters of CML in pediatric and adolescent age groups, along with an assessment of the treatment response with first-line tyrosine kinase inhibitors (TKI) and its correlation with the prognostic scoring systems of adults. Materials and Methods: A retrospective study of 44 Breakpoint Cluster Region-Abelson leukemia virus (BCR-ABL1)-positive pediatric and adolescent CML cases registered at our hospital was done. The clinical and laboratory parameters were evaluated using hospital software. The treatment response was monitored and scoring was performed using mathematical calculations. Results: The mean age was 11.6 (±4.7) years. The median hemoglobin was 8.4 g/dL and 63.6% of the cases showed white blood cell (WBC) counts >250,000/?L. The average follow-up was 21 months. A total of 97.7 and 78.1% cases achieved complete hematological response (CHR) and molecular response, respectively, during the treatment course. The maximum number of patients had low Sokal and European treatment and Outcomes Study (EUTOS) scores. Seventy-five per cent of the cases achieved CHR at 3 months, while 73.6 and 78.6% CML-Chronic phase (CP) cases with low Sokal and EUTOS scores achieved CHR at 3 months, respectively. Conclusion: This study revealed that the CML cases in pediatric and adolescent age groups are normally present with higher WBC counts at the time of diagnosis. The association of the prognostic scoring system with treatment response was statistically insignificant. However, a larger cohort study is needed to determine the treatment response of TKI in children and adolescent CML and its correlation with the prognostic scoring systems.

Risk of renal damage associated with intravitreal anti-VEGF therapy for diabetic macular edema in routine clinical practice

Purpose: Vascular endothelial growth factor inhibitors (anti?VEGF) have been shown to be effective in the treatment of diabetic macular edema. However, there is little information about the systemic effects of intraocular administration of anti?VEGF drugs in patients with coexistent diabetic nephropathy because it can produce adverse renal effects. Methods: This retrospective cohort study analyzed the effect of intravitreal anti?VEGF drugs (bevacizumab, ranibizumab, or aflibercept) on eFGR and microalbuminuria (MicA) in patients with diabetic macular edema and nonproliferative retinopathy without chronic kidney disease (CKD). Results: Sixty?six patients were included, 54.5% male and 45.5% female, with a mean age of 66.70 ± 11.6 years. The mean follow?up of patients with antiangiogenic treatment was 42.5 ± 28.07 months, and the mean number of injections was 10.91 ± 7.54. In 12.1% of the cases, there was a worsening of the glomerular filtration rate (eFGR) and a 19.7% worsening of the microalbuminuria (MicA). The number of injections was not related to the worsening of the eFGR (P = 0.74) or the MicA (P = 0.239). No relationship was found between the type of drug and the deterioration of the GFR (P = 0.689) or the MicA (P = 0.53). Conclusions: Based on the results, there is a small proportion of patients with increase in MicA and the decrease in eFGR after anti?VEGF therapy, and these was no associated with the number of injection or the drug type. Ophthalmologists should be aware of renal damage in order to do a close monitoring of renal function and proteinuria after intravitreal administration of anti?VEGF mainly in hypertensive patients.

Angioedema por enalapril. Presentación de un caso

Los inhibidores de la enzima convertidora de angiotensina son utilizados por más de 40 millones de personas en todo el mundo para el tratamiento de enfermedades cardiovasculares. Son considerados seguros, aunque pueden producir angioedema severo en el 0,1 a 0, 5 % de los pacientes. Se presenta el caso de un paciente del sexo masculino, de 67 años de edad, con diagnóstico de diabetes mellitus e hipertensión arterial, tratado con metformina, hidroclorotiazida y enalapril desde hacía aproximadamente cuatro años, que ingresó en cuerpo de guardia con edema severo del tercio anterior de la lengua, sin compromiso respiratorio. Se indicó hidrocortisona y difenhidramina y evolucionó satisfactoriamente, por lo que fue dado de alta y se prescribió prednisona y difenhidramina por vía oral; se suspendió el enlapril y a las 48 horas se reevaluó y estaba asintomático. El mecanismo por el que estos medicamentos producen angioedema no está claro, pero probablemente sería por la acumulación tisular de bradiquinina y puede presentarse en cualquier momento del tratamiento. La correcta anamnesis, el diagnóstico precoz y el tratamiento inmediato con hidrocortisona por vía endovenosa son aspectos a considerar ante casos similares. El análisis del evento mediante la farmacovigilancia, permitió clasificarlo como severo, probablemente relacionado con el consumo de enalapril. Esto genera alertas para informar al personal de salud y tomar decisiones relacionadas con los medicamentos, que permitan la actuación inmediata con la finalidad de reducir la morbimortalidad.

Angiotensin converting enzyme inhibitors are used by more than 40 million people worldwide for the treatment of cardiovascular diseases. They are considered safe, although they can cause severe angioedema in 0.1 to 0.5% of patients. The case of a 67-years-old male patient diagnosed with diabetes mellitus and arterial hypertension, treated with metformin, hydrochlorothiazide and enalapril for approximately four years, who was admitted to the emergency room with severe edema of the third anterior of the tongue, without respiratory compromise is presented. Hydrocortisone and diphenhydramine were indicated and he evolved satisfactorily, for which he was discharged and prednisone and diphenhydramine were prescribed orally; he discontinued enlapril, 48 hours later he was reassessed and was asymptomatic. The mechanism by which these drugs produce angioedema is not clear, but it would probably be due to the tissue accumulation of bradykinin and can occur at any time during treatment. The correct history, early diagnosis and immediate treatment with intravenous hydrocortisone are aspects to consider in similar cases. Analysis of the event through pharmacovigilance allowed it to be classified as severe, probably related to the enalapril consumption. This generates alerts to inform health staff and make decisions related to medications, which allow immediate action in order to reduce morbidity and mortality.

Diabetes mellitus tipo 1 de presentación súbita inducida por inhibidores del punto de control inmunitario en el tratamiento de cáncer avanzado. Serie de casos / Sudden onset type 1 diabetes mellitus induced by immune checkpoint inhibitors in the treatment of advanced cancer. Cases report

Tres pacientes con cáncer avanzado en tratamiento con inhibidores del punto de control inmunitario (inmune checkpoint inhibitors, ICIs), sin antecedentes de diabetes mellitus (DM), ingresaron al Servicio de Urgencias con poliuria, polidipsia y pérdida de peso, y diagnóstico de cetoacidosis diabética, sin evidencia clínica de infección. Fueron tratados con líquidos e infusión de insulina pasando luego a un régimen de insulina bolo basal que continuó después del alta. Las pruebas de detección de autoanticuerpos para DM resultaron negativas, y se les diagnosticó DM inducida por ICIs, pembrolizumab en dos de ellos y nivolumab en el otro. El propósito de esta serie de casos es demostrar el desarrollo de la DM1 en forma aguda en pacientes tratados con inhibidores de PD-1. Sobre la base de estos casos y la literatura revisada, se buscaron determinar las características clínicas, y sugerir estrategias para la identificación, control, tratamiento precoz y seguimiento de los pacientes tratados con ICIs a fin de minimizar el impacto de la disfunción autoinmune.

Three patients with advanced cancer, treated with inmune checkpoint inhibitors (ICIs), with no history of diabetes mellitus (DM), were admitted to the Emergency Department with polyuria, polydipsia, and weight loss and a diagnosis of diabetic ketoacidosis without clinical evidence of infection. They were treated with fluids and insulin infusion transitioning to a basal-bolus insulin regimen, which continued after discharge. Autoantibody detection tests for DM were negative and they were diagnosed with DM induced by ICIs, pembrolizumab in two of them, and nivolumab in another. The purpose of this case report is to show the development of DM1 in an acute form in patients treated with PD-1 inhibitors. Based on these cases and the reviewed literature, we seek to identify clinical characteristics and suggest strategies for the proper identification, control, treatment, and follow-up of patients treated with ICIs to minimize the impact of autoimmune dysfunction.

Netarsudil monotherapy as the initial treatment for open-angle glaucoma and ocular hypertension in Indian patients: A real-world evaluation of efficacy and safety

Purpose: Glaucoma is the second leading cause of blindness worldwide, affecting more than 64 million people aged 40–80. The best way to manage primary open?angle glaucoma (POAG) is by lowering the intraocular pressure (IOP). Netarsudil is a Rho kinase inhibitor, the only class of antiglaucoma medications that reorganizes the extracellular matrix to improve the aqueous outflow through the trabecular pathway. Methods: An open?label, real?world, multicentric, observation?based 3?month study was performed for assessing the safety and ocular hypotensive efficacy of netarsudil ophthalmic solution (0.02% w/v) in patients with elevated IOP. Patients were given netarsudil ophthalmic solution (0.02% w/v) as a first?line therapy. Diurnal IOP measurements, best?corrected visual acuity, and adverse event assessments were recorded at each of the five visits (Day?1: screening day and first dosing day; subsequent observations were taken at 2 weeks, 4 weeks, 6 weeks, and 3 months). Results: Four hundred and sixty?nine patients from 39 centers throughout India completed the study. The mean IOP at baseline of the affected eyes was 24.84 ± 6.39 mmHg (mean ± standard deviation). After the first dose, the IOP was measured after 2, 4, and 6 weeks, with the final measurement taken at 3 months. The percentage reduction in IOP in glaucoma patients after 3 months of once?daily netarsudil 0.02% w/v solution use was 33.34%. The adverse effects experienced by patients were not severe in the majority of cases. Some adverse effects observed were redness, irritation, itching, and others, but only a small number of patients experienced severe reactions, as reported in a decreasing order: redness > irritation > watering > itching > stinging > blurring. Conclusion: We found that netarsudil 0.02% w/v solution monotherapy when used as the first?line treatment in primary open?angle glaucoma and ocular hypertension was both safe and effective.

Omeprazole-induced cardiac arrhythmia – A case report

Omeprazole, a Proton pump inhibitor, is widely prescribed in patients with chronic gastroesophageal reflux. Patients continue to use omeprazole for long period of time even without the supervision of the doctor. The authors report a 50-year-old male patient with a 5-year history of omeprazole use, who complained of chest discomfort. ECG on admission showed atrial fibrillation. Laboratory findings showed hypomagnesaemia, hypocalcaemia, and hypokalemia. The case report emphasizes the importance of patient education regarding the use and adverse drug reactions of the prescribed medications.

Merkel cell carcinoma: epidemiology, clinical features, diagnosis and treatment of a rare disease

Abstract Merkel cell carcinoma is a rare skin cancer with neuroendocrine differentiation. The risk factors include sun exposure, advanced age, immunosuppression (such as transplant recipients, patients with lymphoproliferative neoplasms, or patients with HIV), and Merkel cell polyomavirus infection. Clinically, Merkel cell carcinoma appears as a cutaneous or subcutaneous plaque or nodule, but this tumor diagnosis is rarely made clinically. Therefore, histopathology and immunohistochemistry are usually necessary. Primary tumors without evidence of metastases are treated with complete surgical excision and appropriate surgical margins. The presence of occult metastasis in a lymph node is frequent and a sentinel lymph node biopsy should be performed. Postoperative adjuvant radiotherapy increases local tumor control. Recently, agents that block the PD-1/PD-L1 pathway have shown objective and durable tumor regression in patients with advanced solid malignancies. The first anti-PD-L1 antibody used in patients with Merkel cell carcinoma was avelumab, but pembrolizumab and nivolumab have also shown efficacy. This article describes the current state of knowledge of the epidemiology, diagnosis, and staging of Merkel cell carcinoma, as well as new strategies for its systemic treatment.

Limitaciones de los puntajes de riesgo cardiovascular en prevención primaria. ¿Una oportunidad para los moduladores de riesgo? / Limitations of cardiovascular risk scores in primary prevention. An opportunity for risk modulators?

RESUMEN Introducción : Los puntajes de riesgo cardiovascular tienen limitaciones relacionadas con la calibración, la discriminación y la baja sensibilidad. Se han identificado diferentes "moduladores de riesgo" que permiten mejorar la estratificación del riesgo cardiovascular: placa aterosclerótica carotídea (PAC), puntaje de calcio arterial coronario (pCAC) y lipoproteína(a) [Lp(a)]. Objetivos : 1) determinar la prevalencia de los moduladores de riesgo citados en una población en prevención primaria; 2) determinar la concordancia entre los 2 métodos de detección de aterosclerosis subclínica; 3) establecer qué proporción de pacientes deberían recibir estatinas inicialmente, según su puntaje de riesgo, y posteriormente con el conocimiento de los moduladores de riesgo. Material y métodos : Se incluyeron individuos de 18 a 79 años, que asistieron para una evaluación de riesgo cardiovascular y que no estaban recibiendo tratamiento hipolipemiante. Se calculó el puntaje de riesgo (ASCVD Risk Estimator) en cada paciente. Se evaluó la presencia de PAC, el pCAC y el nivel plasmático de Lp(a). Resultados : Se incluyeron 348 pacientes (edad media 55,6 ± 12,2 años, 45,4% hombres). En la población total, 29,8%, 36,8% y 53,2% de los pacientes mostraron un valor de Lp(a) ≥ 50 mg/dL, PAC o un pCAC > 0, respectivamente. La prevalencia de PAC y pCAC fue progresivamente mayor según la categoría de riesgo cardiovascular; sin embargo, la proporción de sujetos de bajo riesgo que tenían moduladores de riesgo fue considerable (Lp(a) ≥ 50 mg/dl: 25,7%; PAC: 22%; pCAC > 0: 33%). En los 60 individuos menores de 45 años la prevalencia de pCAC > 0 y PAC fue de 18,3% y 10%, respectivamente. La concordancia entre los dos métodos para determinar la presencia de ateromatosis subclínica fue discreta (kappa 0,33). La indicación del tratamiento con estatinas aumentó un 31,6% luego de evaluar la presencia de moduladores. Conclusión : La presencia de moduladores de riesgo fue frecuente en esta población en prevención primaria, incluso en sujetos de bajo riesgo o menores de 45 años. La detección de moduladores de riesgo podría mejorar la estratificación inicial y llevar a reconsiderar el tratamiento con estatinas.

ABSTRACT Background : Cardiovascular risk scores have limitations related to calibration, discrimination, and low sensitivity. Different "risk modulators" have been identified to improve cardiovascular risk stratification: carotid atherosclerotic plaque (CAP), coronary artery calcium (CAC) score and lipoprotein(a) [Lp(a)]. Objectives : The aims of this study were: 1) to determine the prevalence of risk modulators mentioned in a primary prevention population; 2) determine the concordance between the 2 methods of detecting subclinical atherosclerosis; and 3) establish which proportion of patients should receive statins according to the initial risk stratification and after being recategorized by screening for risk modulators. Methods : Individuals aged 18 to 79 years who consulted for cardiovascular risk assessment and who were not receiving lipid-lowering treatment were included. The risk score was calculated in each patient using ASCVD Risk Estimator. The presence of CAP, CAC score and Lp(a) level were evaluated. Results : The cohort was made up of 348 patients; mean age was 55.6 ± 12.2 years and 45.4% were men. In the total population, 29.8%, 36.8%, and 53.2% of patients showed Lp(a) value ≥50 mg/dL, CAP, or a CAC score >0, respectively. The prevalence of CAP and CAC score was progressively higher according to the cardiovascular risk category; however, the proportion of low-risk subjects who had risk modulators was considerable (Lp(a) ≥50 mg/dl: 25.7%; CAP: 22%; CAC score >0: 33%). In the 60 subjects <45 years, the prevalence of CAC score >0 and CAP was 18.3% and 10%, respectively. The agreement between the two methods for quantifying subclinical atheromatosis was fair (kappa= 0.33). The indication for statin treatment increased by 31.6% after evaluating the presence of modulators. Conclusion : The presence of risk modulators was common in this population in primary prevention, even in low-risk subjects or < 45 years. Detection of risk modulators could improve initial stratification and lead to reconsideration of statin treatment.
