Dynamic nature of BRAF or KRAS p.G12C mutations in second-line therapy for advanced colorectal cancer patients: do early and late effects exist?

INTRODUCTION: The mitogen-activated protein kinase (MAPK) signalling network aberrations in metastatic colorectal cancer (mCRC) generate intrinsic dynamic effects and temporal variations that are crucial but often overlooked in clinical trial populations. Here, we investigate the time-varying impact of MAPK pathway mutation genotype on each treatment line's contribution to the overall clinical course. METHODS: The PROMETEO study focused on mCRC patients undergoing second-line treatment at 20 hospitals. We evaluated genotypes and employed flexible models to analyse the dynamic effect of each mutation. RESULTS: We examined data derived from 1160 patients. The effects of KRAS G12C or G12V, and BRAF V600E are clearly time-varying, with unexpected consequences such as the deleterious effect of BRAF V600E vs other genotypes dissipating over time when subjects receive antiangiogenics, or KRAS G12V and G12C showing increasing aggressiveness over time. Thus, contrary to expectations, the 12-month survival rate from the second line for those who survived >6 months was 49.9% (95% CI, 32.7-67.3) for KRAS G12C and 59% (95% CI, 38.5-80.6) for BRAF V600E. CONCLUSIONS: The dynamic perspective is essential for understanding the behaviour of tumours with specific genotypes, especially from the second line onward. This may be relevant in patient monitoring and treatment decision-making, particularly in cases with distinct mutations.

Maintenance of angiogenesis inhibition with aflibercept after progression to bevacizumab in metastatic colorectal cancer: real life study in the Valencian community

Introduction The second-line chemotherapy in metastatic colorectal cancer (mCRC) with FOLFIRI-aflibercept demonstrated an increase in survival compared with FOLFIRI in patients previously treated with oxaliplatin-based regimens. Few data are available in patients treated previously with bevacizumab. Our objective is to evaluate the efficacy and safety of FOLFIRI-aflibercept in second-line treatment in patients who have previously received bevacizumab. Patients and methods This is a observational, retrospective study of patients with mCRC treated with FOLFIRI-aflibercept in 2nd line in eight hospitals in the Valencian Community. Survival, response, and toxicity were analyzed. Result 122 patients with a median age of 61 years were included. 89% of patients had PS 0–1. The median of PFS (progression free survival) and OS (overall survival) was 5.45 (95% CI 4.74–6.15 months) and 10.15 (95% CI 7.47–12.82 months), respectively. Disease control rate 59.8%. The most common grade 3–4 adverse events were neutropenia (13,1%) and asthenia (9%). The presence of hypertension during treatment with FOLFIRI-aflibercept was associated with a survival benefit. Median of OS was 14.45 (95% CI 11.58–17.32) in patients with hypertension vs 7.78 (95% CI 5.02–10.54) in patients without hypertension (p = .001). Our results suggest that the presence of PS 0, primary tumor surgery, metachronous metastases, and the presence of only 1 metastatic location, are favorable prognostic factors associated with better OS. Conclusions Our results confirm the value of maintaining angiogenesis inhibition with FOLFIRI-aflibercept in mCRC after progression to a first-line treatment with bevacizumab. The development of hypertension during treatment is a possible predictive marker of response (AU)

Understanding factors that influence whether a woman will seek care for reproductive health: A national survey.

A number of studies have characterized the importance of regular OB/GYN visits for women who are above the age of 18. As more emphasis is placed on reproductive healthcare, there has been an overall decrease in the rates of adverse sexual and reproductive health outcomes. In this study, a population of 200 women were surveyed to find factors that influence whether they had sought care from an OB/GYN in the past year. These results can be further extrapolated to whether women will seek OB/GYN healthcare in the future. A survey research platform was used to collect demographic data in addition to the survey responses. Thirteen survey questions were designed, some of which were adapted from the NIH Healthcare Access and Utilization Survey. This study found that women of minority races (African American and Hispanic) were more likely to report that they didn't feel like they were asked for their opinions about their healthcare. Additionally, women who were younger, who didn't feel like they were asked for their opinions, and who were of minority races were more likely to have not seen an OB/GYN in the past year. These findings can be used to focus on fixing the factors that deter women from seeking regular OB/GYN care. Efforts must be made to ensure that patients feel supported and understood, for this is the only way that we can make progress towards a healthier society.

Transvaginal Ultrasound Diagnosis of Ovarian Ectopic Pregnancy.

Primary ovarian pregnancies are rare and comprise less than one percent of all ectopic pregnancies. Diagnosis can be difficult as an ovarian ectopic pregnancy may share similar features on ultrasound with those of a corpus luteal cyst. Findings on transvaginal ultrasound, including a hyperechoic ring, may denote the presence of a gestational sac and therefore an ovarian ectopic pregnancy. Ultrasonographic findings, as well as a strong suspicion of an ovarian ectopic pregnancy, are critical. The report reviews the case of a 23-year-old primigravida with first trimester bleeding, an elevated human chorionic gonadotropin, an ovarian cyst, and no intrauterine pregnancy detected on ultrasound. The evaluation, diagnosis, and surgical management of an ovarian ectopic pregnancy are discussed.

Survival, response, and toxicity were analyzed. RESULTS: 122 patients with a median age of 61 years were included. 89% of patients had PS 0-1. The median of PFS (progression free survival) and OS (overall survival) was 5.45 (95% CI 4.74-6.15 months) and 10.15 (95% CI 7.47-12.82 months), respectively. Disease control rate 59.8%. The most common grade 3-4 adverse events were neutropenia (13,1%) and asthenia (9%). The presence of hypertension during treatment with FOLFIRI-aflibercept was associated with a survival benefit. Median of OS was 14.45 (95% CI 11.58-17.32) in patients with hypertension vs 7.78 (95% CI 5.02-10.54) in patients without hypertension (p = .001). Our results suggest that the presence of PS 0, primary tumor surgery, metachronous metastases, and the presence of only 1 metastatic location, are favorable prognostic factors associated with better OS. CONCLUSIONS: Our results confirm the value of maintaining angiogenesis inhibition with FOLFIRI-aflibercept in mCRC after progression to a first-line treatment with bevacizumab. The development of hypertension during treatment is a possible predictive marker of response.

Introducción: las infecciones estreptocócicas pueden presentarse con fiebre, inflamación faringoamigdalina con o sin exudados, petequias en el paladar, adenitis cervical, exantema escarlatiniforme y / o dolor abdominal. Resulta útil en área de urgencia disponer de pruebas de detección rápida de antígenos de S. pyogenes (DRASP) de alta especificidad y sensibilidad algo menor. Objetivos: conocer la utilidad de un test de DRASP en 2 servicios de Urgencia Pediátrica, describiendo las características clínicas y epidemiológicas de los pacientes estudiados durante el período de la investigación y su correlación con el cultivo de exudado faríngeo mediante el cálculo de sensibilidad (S), especificidad (E), valor predictivo positivo (VPP) y valor predictivo negativo (VPN). Material y métodos: estudio prospectivo, observacional, transversal en dos servicios de emergencia pediátrica. Se incluyeron niños a los que se les realizó DRASP y exudado faríngeo (EF) entre el 14 de febrero y el 13 de abril de 2018. Se registró: sexo, edad, motivo de consulta, diagnóstico, tratamiento, destino, resultado del test y de cultivo faríngeo. Se calcularon S, E, VPP y VPN. Resultados: n=241 niños. Rango 8 meses - 14 años, media 6 años. Consultaron por fiebre 103 niños (42,7%); por odinofagia 48, por erupción 11 y 47 por otros síntomas. Al 95% de los niños se le otorgó el alta. DRASP negativos 87,6% (N: 211) y positivos 12,9% (N: 31). EF negativos 80,1% (n: 193) y positivos para SßHGA en 13,7% (n: 33). La sensibilidad de la prueba fue del 52% y su especificidad del 93%. El VPP 55% y el negativo 92%. El diagnóstico más frecuente fue faringitis viral 132 (54,7%). Conclusiones: el test se aplicó fundamentalmente a escolares febriles, algunos con odinofagia. Contribuye a diferenciar en forma rápida la etiología y habilita a no usar antibióticos en caso de resultado negativo. Estos resultados avalan el uso de DRASP en la urgencia pediátrica.

Introduction: streptococcal infections can show fever, pharyngotonsillar inflammation with or without swabs, palatal petechiae, cervical adenitis, scarlatiniform rash and/or abdominal pain. Rapid detection tests for S. pyogenes antigens (DRASP) with high specificity and somewhat lower sensitivity are a useful at the Emergency Ward. Objectives: know the usefulness of a DRASP test in 2 Pediatric Emergency, describe the clinical and epidemiological characteristics of the patients studied during the research period and its correlation with the culture of pharyngeal exudates by calculating sensitivity (S) , specificity (S), positive predictive value (PPV), and negative predictive value (NPV). Material and Methods: prospective, observational, cross-sectional study carried out in two pediatric emergency wards. We included children who underwent DRASP and pharyngeal swab (PS) between February 14 and April 13, 2018. The following data were recorded: sex, age, reason for consultation, diagnosis, treatment, destination, test results and throat cultures. S, S, PPV and NPV were calculated. Results: n=241 children. Range 8 months - 14 years, average 6 years. 103 children (42.7%) consulted due to fever; 48 due to sore throat, 11 due to rash and 47 due to other symptoms. 95% of children were discharged. DRASP negative 87.6% (N: 211) and positive 12.9% (N: 31). Negative EP 80.1% (n: 193) and positive for SßHGA in 13.7% (n: 33). The test sensitivity was 52% and specificity 93%. The PPV 55% and the negative 92%. The most frequent diagnosis was viral pharyngitis 132 (54.7%). Conclusions: the test was applied mainly to febrile schoolchildren, some with odynophagia. A quick etiology differentiation is helpful, since it prevents antibiotics from being used in the event of a negative result. These results support the use of DRASP in pediatric emergency wards.

A rápida diferenciação etiológica é útil, pois evita o uso de antibióticos em caso de resultado negativo. Esses resultados apoiam o uso do DRASP em enfermarias de emergência pediátrica.

Ascending Aortic Aneurysm With Dissection in the Second Trimester of Pregnancy.

Aortic aneurysm in pregnancy is uncommon. A dissecting aortic aneurysm in pregnancy is less common. If present, a dissecting aortic aneurysm can lead to poor outcomes for both the mother and the fetus, including death. Swift recognition of the signs and symptoms of a dissecting aortic aneurysm can prevent a delay in diagnosis and possibly improve maternal-fetal outcomes. The report discusses a case of a pregnant patient who experienced a dissecting aortic aneurysm in the second trimester despite having none of the commonly associated risk factors. The evaluation, diagnosis, and surgical management of dissecting aortic aneurysm in pregnancy are discussed.

Threatened Miscarriage in a COVID-19 Patient.

Introducción: El lupus eritematoso sistémico (LES), prototipo de enfermedad autoinmune, cursa con empujes y remisiones. Dada la diversidad de presentaciones posibles, su diagnóstico y tratamiento son un reto para el clínico, y se requiere tener un alto índice de sospecha. Objetivo: presentar el caso clínico de un adolescente que debuta con LES a forma de anemia hemolítica, probablemente gatillado por infección por virus de Epstein Barr. Caso clínico: Varón de 14 años, sin antecedentes a destacar. Consulta por fiebre de 7 días de evolución de hasta 39º C, odinofagia, astenia y adinamia. Al examen físico se constata palidez cutáneo mucosa, ictericia, adenopatías cervicales y hepatoesplenomegalia. El laboratorio muestra anemia severa regenerativa con aumento de las bilirrubinas a expensas de la indirecta sin hepatitis. Prueba de Coombs positiva. Anticuerpos específicos para Epstein Barr positivos, con lo que se diagnostica anemia hemolítica secundaria a mononucleosis y se inicia tratamiento corticoideo. En la evolución agrega eritema malar y limitación en flexión de codos y rodillas. Se reciben anticuerpos antinucleares y anti ADN nativo positivos con hipocomplementemia severa. Con diagnóstico de LES se inicia hidroxicloroquina y azatioprina, manteniéndose la prednisona. Conclusiones: Muchos virus (hepatitis C, Parvovirus B19, Epstein Barr y Citomegalovirus) se han descrito como posibles inductores o simuladores de LES. Es necesario mantener un alto índice de sospecha para realizar un diagnóstico oportuno y tratamiento precoz.

Introduction: Systemic lupus erythematosus (SLE), prototype of autoimmune disease, progresses with flares and remissions. Given the diversity of possible presentations, its diagnosis and treatment are a challenge for the clinician, and a high index of suspicion is required. Objective: To present the clinical case of an adolescent who debuted with SLE in the form of hemolytic anemia, probably triggered by Epstein Barr virus infection. Clinical case: 14 - year - old male, with no history to highlight. Consultation for fever of 7 days of evolution of up to 39º C, odynophagia, asthenia and adynamia. Physical examination revealed mucous skin pallor, jaundice, cervical lymphadenopathy, and hepatosplenomegaly. The laboratory shows severe regenerative anemia with increased bilirubin at the expense of indirect without hepatitis. Positive Coombs test. Specific antibodies for Epstein Barr were positive, with which hemolytic anemia secondary to mononucleosis was diagnosed and corticosteroid treatment was started. In the evolution, it adds malar erythema and limitation in flexion of the elbows and knees. Positive antinuclear and anti-native DNA antibodies are received with severe hypocomplementemia. With a diagnosis of SLE, hydroxychloroquine and azathioprine were started, maintaining prednisone. Conclusions: Many viruses (hepatitis C, Parvovirus B19, Epstein Barr and Cytomegalovirus) have been described as possible inducers or mimics of SLE. It is necessary to maintain a high index of suspicion for timely diagnosis and early treatment.

En 2021 aumentaron los sintomáticos, la cefalea y las infecciones intrafamiliares (p <0,05). El porcentaje de contagios en centros educativos tuvo un descenso estadísticamente significativo. Conclusiones: en ambos periodos predominaron los escolares, con aparición de casos en niños menores de un año en 2021. Los niños se contagiaron en domicilio. Los pacientes sintomáticos predominaron en 2021, en particular aquellos con cefalea.

Summary: Introduction: in March 2020, the WHO declared the COVID-19 pandemic. In Uruguay, more than 60,000 children have had the disease, 500 of them requiring hospitalization. Three died. Objectives: to describe the epidemiological characteristics of children under 15 years of age diagnosed with COVID-19 controlled in an outpatient follow-up program, their epidemiological trace, and to compare results for 2020 and 2021. Methodology: descriptive study of children under 15 years of age with etiological confirmation of SARS-CoV-2 assisted by the program between March 2020 and June 2021. Variables: sex, age, origin, epidemiological link and symptoms. Variables were compared between the 2 study periods. Results: 1,328 patients were followed up, 663 (49.9%) male. Under 6 years old, 341 (25.6%), from 6 to 11, 608 (45.7%) and 12 years or older, 379 (28.7%). The epidemiological trace was mainly within the family (867 living together, 144 not living together). In 2020 there were 132 positive patients, 35 (26.5%) under 6 (1 under a year); 66 (50%) symptomatic: 49 upper respiratory symptoms (37.1%), 35 fever (26.5%), 7 headache (5.3%), 60 asymptomatic. In 2021, there were 1,196 positive patients, 306 (25%) under 6 (2 newborns and 43 under 1 year); 791 (66%) symptomatic: 500 upper respiratory symptoms (41.8%), 355 fever (29.7%), headache 212 (17.7%), 352 asymptomatic. In 2021, symptoms, headache and intrafamily infections increased (p < 0.05). The percentage of infections taking place at schools had a statistically significant decrease. Conclusions: in both periods, schoolchildren predominated, with cases appearing in children under one year of age in 2021. The children were infected at home. Symptomatic patients predominated in 2021, particularly those with headache.

Introdução: em março de 2020, a OMS declarou a pandemia de COVID-19. No Uruguai, mais de 60.000 crianças tiveram a doença, 500 delas necessitaram de internação. Três morreram.

Adherence and adverse events of intraperitoneal chemotherapy in optimally debulked ovarian cancer patients: Real-life study.

PURPOSE: Intraperitoneal with intravenous chemotherapy (IP/IV) is the recommended option for patients with stage III cancer with optimally debulked (<1 cm residual) disease based on randomized controlled trials and showing important improvements in overall survival and progression free survival. However, its application has not been largely adopted due to its difficult administration that requires a trained nurse staff. The aim of this work was to study the completion and the toxicity of an IP outpatient chemotherapy regimen in optimally debulked stage III ovarian cancer patients. METHODS: A single-center, retrospective observational study in women with stage III ovarian cancer following optimal cytoreductive surgery (<1 cm) followed by IP/IV chemotherapy from 2009 to 2017. The IP/IV regimen was as it follows: IV paclitaxel 175 mg/m2 in 3 h, day 1; IP cisplatin (100 mg/m2-until December 2013-or 75 mg/m2), day 2; IP paclitaxel 60 mg/m2, day 8, each 21 days for six cycles. RESULTS: A total of 60 patients received IP/IV regimen. Of these, 41 patients (68.3%) completed the six IP chemotherapy cycles and 51 (84.9%) completed four or more cycles. Most of the adverse events reported were non-hematological and G1-2. There was no difference neither in adherence nor in the frequency of adverse events between both cisplatin groups. Despite a high rate of adverse events, IP chemotherapy can be delivered with a high completion rate and manageable toxicity to patients with optimally debulked ovarian cancer.

Haemophilus influenzae type b invasive infections in children hospitalized between 2000 and 2017 in a Pediatric Reference Hospital (PRH).

BACKGROUND: Uruguay incorporated the conjugate vaccine against Haemophilus influenzae b (Hib) in 1994. In 2008, the vaccine was changed from one with natural conjugated capsular polysaccharide to one with a synthetic polysaccharide component. We describe the frequency and characteristics of invasive Hib infections in children hospitalized in a Pediatric Reference Hospital (PRH) between January 1st, 2000 and December 31st, 2017. METHODS: Sterile site Hib isolations from hospitalized children were included. Clinical and microbiological characteristics were analyzed. Favorable conditions for the infection were considered: incomplete immunization, immunodeficiencies and associated pathologies. Two periods are described: 1, prior to vaccine change (1/1 st/2000- 12/31/08) and 2, post-change (1/1 st/09- 12/31st/17). RESULTS: 45 children were hospitalized: 5 in the first period and 40 in the second. The hospitalization rate per 10,000 discharges was 0.41 (95% CI 0.05-0.77) and 4.2/10,000 (95% CI 2.89-5.48), respectively (p < 0.01). The diagnoses at discharge were: meningitis/ventriculitis (20), pneumonia (16), bacteremia (3), epiglottitis (1), arthritis (1), cellulitis (3) and obstruction of the upper airway (1). Four children presented comorbidities. Twenty seven received less than 3 doses of anti-Hib vaccination and 18 were properly vaccinated (2 were immunodeficient). The median hospitalization was 14 days, 18 children required intensive therapy. CONCLUSIONS: Observed change may be due to: incomplete primary series, inhomogeneous vaccine coverage and immunogenicity of the synthetic polysaccharide. To reduce this public health problem, epidemiological surveillance.

Screening de hemoglobina en una población de lactantes / Hemoglobin screening test in a population of infants / Teste de triagem de hemoglobina em uma população de lactentes

La deficiencia de hierro es la causa más frecuente de anemia en pediatría. Su detección precoz, tratamiento correcto y profilaxis adecuada, constituyen una prioridad sanitaria en nuestro país. Objetivo: Describir el screening de hemoglobina realizado en lactantes con edades comprendidas entre 8 y 12 meses, usuarios de un centro de atención pediátrico de Montevideo, en el período comprendido entre 2 de mayo y 31 de octubre de 2015 y evaluar factores de riesgo de anemia ferropénica presentes. Se revisaron sus historias clínicas, consignando datos epidemiológicos, antecedentes perinatales, alimentación recibida y si recibieron suplementación con hierro adecuada. Se registró si se había realizado la medición de hemoglobina por punción digital y el valor medido. Se comparó la prevalencia de factores de riesgo entre niños con y sin anemia. En el período evaluado fueron asistidos 62 niños: 3 pretérminos de 34 semanas o menos; 15 con peso al nacer menor a 3000 gramos; 42 con lactancia materna exclusiva durante 6 meses; 54 con alimentación complementaria adecuada; 45 con suplementación de hierro. Se realizó la medición de hemoglobina por punción digital a 55 niños. Tenían anemia 28 niños (82 % leve). No se encontró asociación de padecer anemia con los factores de riesgo estudiados excepto el cumplimiento de la profilaxis con suplemento de hierro. Concluimos que la prevalencia de anemia en este grupo fue elevada y que la suplementación con hierro es importante para su prevención.

Iron deficiency is the most frequent cause of anemia in pediatrics. Its early detection, correct treatment and adequate prophylaxis, constitute a health priority in our country. Objective: Describe the hemoglobin screening performed in infants aged between 8 and 12 months, users of a pediatric care center from Montevideo, in the period covered between May 2 and October 31, 2015 and evaluate factors of Risk of iron deficiency anemia present. Their clinical histories were reviewed, including epidemiological data, perinatal records, and diet received and if they received adequate iron supplementation. It was recorded if the hemoglobin measurement had been performed by digital puncture and the measured value. The prevalence of risk factors among children with and without anemia was compared. In the evaluated period, 62 children were assisted: 3 preterm subjects of 34 weeks or less; 15 birth weight less than 3,000 grams; 42 exclusive breastfeeding for 6 months; 54 adequate complementary feeding; 45 iron supplementation. The hemoglobin was measured by digital puncture to 55 children. 28 of them had anemia (82 % mild). No association of anemia was found with the risk factors studied except compliance with prophylaxis with iron supplementation. We conclude that the prevalence of anemia in this group was high and that iron supplementation is important for its prevention.
