RESUMO

The benefit of adding the antiangiogenic drug aflibercept to FOLFIRI regime in metastatic colorectal cancer (CRC) patients resistant to or progressive on an oxaliplatin-based therapy has been previously demonstrated. However, the absence of validated biomarkers to predict greater outcomes is a major challenge encountered when using antiangiogenic therapies. In this study we investigated profiles of circulating microRNAs (miRNAs) to build predictive models of response to treatment and survival. Plasma was obtained from 98 metastatic CRC patients enrolled in a clinical phase II trial before receiving FOLFIRI plus aflibercept treatment, and the circulating levels of 754 individual miRNAs were quantified using real-time PCR. A distinct signature of circulating miRNAs differentiated responder from non-responder patients. Remarkably, most of these miRNAs were found to target genes that are involved in angiogenic processes. Accordingly, some of these miRNAs had predictive value and entered in predictive models of response to therapy, progression of disease, and survival of patients treated with FOLFIRI plus aflibercept. Among these miRNAs, circulating levels of hsa-miR-33b-5p efficiently discriminated between responder and non-responder patients and predicted the risk of disease progression. Moreover, the combination of circulating VEGF-A and miR-33b-5p levels improved clinical stratification of metastatic CRC patients who were to receive FOLFIRI plus aflibercept treatment. In conclusion, our study supports circulating miRNAs as valuable biomarkers for predicting better outcomes in metastatic CRC patients treated with FOLFIRI plus aflibercept.

RESUMO

Atypical uremic haemolytic syndrome is a variant of thrombotic micro-andiopathy characterized by non-autoimmune hemolytic anemia, thrombocytopenia and acute renal failure as a result of excessive activation of the complement. Up to 60% of patients have mutations in the genes that encode the complement system. A disensing factor is required for its manifestation, including gestation. It is an entity with a high morbidity, which can decrease drastically if an early diagnosis is made and appropriate treatment is initiated. Administration of ecuilizumab has demonstrated rapid process disruption, reducing the need for extrarenal purification therapies and improving renal function and patient prognosis.

RESUMO

El síndrome hemolítico urémico atípico es una variante de la microangiopatía trombótica caracterizada por presentar anemia hemolítica no autoinmune, trombocitopenia y fallo renal agudo como consecuencia de una excesiva activación del Sistema del complemento. Hasta en un 60% de los pacientes presentan mutaciones en los genes que codifican el sistema del complemento. Se requiere un factor desencadenante para su manifestación, entre los que se encuentra la gestación. Es una entidad que presenta una elevada morbimortalidad, que puede disminuir de forma relevante si se realiza un diagnóstico precoz y se inicia tratamiento adecuado. La administración de eculizumab ha demostrado la interrupción rápida del proceso, con reducción de la necesidad de terapias de depuración extrarrenal y mejoría de la función renal y pronóstico de las pacientes.(AU)

RESUMO

BACKGROUND: We explored the influence of BRAF and PIK3CA mutational status on the efficacy of bevacizumab or cetuximab plus 5-fluorouracil/leucovorin and irinotecan (FOLFIRI) as first-line therapy in patients with RAS wild-type metastatic colorectal cancer (mCRC). PATIENTS AND METHODS: VISNÚ-2 was a multicentre, randomised, phase II study. Patients with RAS wild-type mCRC and <3 circulating tumour cells/7.5 ml blood were stratified by BRAF/PIK3CA status (wild-type versus mutated) and number of affected organs (1 versus >1), and allocated to bevacizumab (5 mg/kg every 2 weeks) or cetuximab (400 mg/m2 then 250 mg/m2 weekly) plus FOLFIRI [irinotecan 180 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil 400 mg/m2 (bolus) then 2400 mg/m2 (46-h continuous infusion) every 2 weeks]. The primary endpoint was progression-free survival (PFS). All analyses were exploratory. RESULTS: Two hundred and forty patients with BRAF/PIK3CA wild-type (n = 196) or BRAF- and/or PIK3CA-mutated tumours (n = 44) were enrolled. Median PFS was 12.7 and 8.8 months in patients with BRAF/PIK3CA wild-type and BRAF/PIK3CA-mutated tumours, respectively [hazard ratio (HR) = 1.22; 95% confidence interval (CI) 0.80-1.85; P = 0.3602]. In the BRAF- and/or PIK3CA-mutated cohort, median PFS was 2.8, 8.8 and 15.0 months in patients with BRAF/PI3KCA-mutated (n = 8), BRAF-mutated/PI3KCA wild-type (n = 16) and BRAF wild-type/PI3KCA-mutated (n = 20) tumours, respectively (P = 0.0002). PFS was similar with bevacizumab plus FOLFIRI versus cetuximab plus FOLFIRI in BRAF/PIK3CA wild-type (HR = 0.99; 95% CI 0.67-1.45; P = 0.9486) and BRAF/PIK3CA-mutated tumours (HR = 1.11; 95% CI 0.53-2.35; P = 0.7820). The most common grade 3/4 treatment-related adverse events were neutropenia, diarrhoea and asthenia in both treatment groups. CONCLUSIONS: BRAF/PIK3CA status influences outcomes in patients with RAS wild-type mCRC but does not appear to assist with the selection of first-line targeted therapy.

RESUMO

PURPOSE: The primary aim of this retrospective study was to describe the treatment patterns according to the type of treatment received by patients with metastatic colorectal cancer (mCRC) in Spain. METHODS: This was a retrospective, observational, multicenter study performed by 33 sites throughout Spain that included consecutive patients aged 18 years or older who had received or were receiving treatment for mCRC. RESULTS: At the time of inclusion, of the 873 evaluable patients, 507 (58%) had received two lines, 235 (27%) had received three lines, 106 (12%) had received four lines, and the remaining patients had received up to ten lines. The most frequent chemotherapy schemes were the FOLFOX or CAPOX regimens (66%) for first-line treatment, FOLFOX, CAPOX or FOLFIRI (70%) for second-line treatment, and FOLFOX, FOLFIRI or other fluoropyrimidine-based regimens for third- and fourth-line (over 60%) treatment. Sixty percent of patients received targeted therapy as part of their first-line treatment, and this proportion increased up to approximately 70% of patients as part of the second-line of treatment. A relevant proportion of patients were treated with unknown KRAS, and especially the BRAF, mutation statuses. CONCLUSIONS: This study reveals inconsistencies regarding adherence to the recommendations of the ESMO guidelines for the management of mCRC in Spain. Improved adherence to the standard practice described in such guidelines for the determination of RAS and BRAF mutation statuses and the use of targeted therapies in first-line treatment should be considered to guarantee that patients can benefit from the best therapeutic approaches available.

RESUMO

BACKGROUND: Treatment of frail patients with advanced colorectal cancer (CRC) is controversial. This pilot phase II trial aimed to assess the efficacy and safety of regorafenib when administered in first-line to frail patients with advanced CRC. METHODS: Frail patients without prior advanced colorectal cancer treatment were included in the study. Definition of frailty was defined per protocol based on dependency criteria, presence of chronic comorbid pathologies and/or geriatric features. MAIN OBJECTIVE: to assess progression-free survival (PFS) rate at 6 months. Treatment consisted of 28-day cycles of orally administered regorafenib 160 mg/day (3 weeks followed by 1 week rest). RESULTS: Forty-seven patients were included in the study. Median age was 81 years (range 63-89). Frailty criteria: dependency was observed in 26 patients (55%), comorbidities in 27 (57%) and geriatric features in 18 (38%). PFS rate at 6 months was 45% (95% confidence interval [CI] 30-60]. Median PFS was 5.6 months (95%CI 2.7-8.4). Median overall survival (OS) was 16 months (95%CI 7.8-24). Complete response, partial response and stable disease were observed in one, two and 21 patients respectively (objective response rate 6.4%; disease control rate 51%). Thirty-nine patients (83%) experienced grade 3-4 adverse events (AEs). The most common grade 3-4 AEs were hypertension (15 patients; 32%), asthenia (14; 30%), hypophosphatemia (6; 13%); diarrhea (4; 8%), hand-foot-skin reaction (4; 8%). There were two toxic deaths (4.2%) (grade 5 rectal bleeding and death not further specified). Dose reduction was required in 26 patients (55%) and dose-delays in 13 patients (28%). CONCLUSIONS: The study did not meet the pre-specified boundary of 55% PFS rate at 6 months. Toxicity observed (83% patients experienced grade 3 and 4 AEs) preclude its current use in clinical practice on this setting. Disease control rate and overall survival results are interesting and might warrant further investigation to identify those who benefit from this approach. TRIAL REGISTRATION: This trial was prospectively registered at EudraCT ( 2013-000236-94 ). Date of trial registration: April 9th, 2013.

RESUMO

The systematic study of nanoparticle-biological interactions requires particles to be reproducibly dispersed in relevant fluids along with further development in the identification of biologically relevant structural details at the materials-biology interface. Here, we develop a biocompatible long-term colloidally stable water dispersion of few-layered graphene nanoflakes in the biological exposure medium in which it will be studied. We also report the study of the orientation and functionality of key proteins of interest in the biolayer (corona) that are believed to mediate most of the early biological interactions. The evidence accumulated shows that graphene nanoflakes are rich in effective apolipoprotein A-I presentation, and we are able to map specific functional epitopes located in the C-terminal portion that are known to mediate the binding of high-density lipoprotein to binding sites in receptors that are abundant in the liver. This could suggest a way of connecting the materials' properties to the biological outcomes.

RESUMO

Nanomedicine, nanotargeting and nanotherapeutics have in the last few years faced several difficulties in translating the promising results obtained in vitro to an in vivo scenario. The origin of this discrepancy might be found in the lack of a detailed and realistic characterization of the biological surface of nanoparticles. Despite the capability to engineer nanomaterials with a great variety and a precise control of the surface functionalization, the targeting capability is lost when the nanoparticles are embedded in complex biological media, due to the formation of a biological layer (biomolecular corona). This biological layer represents the ultimate nanoparticle surface, likely to interact with the cell machinery. Therefore, in addition to traditional nanoparticle characterization techniques, a more insightful investigation of the biomolecular corona is needed, including the capability to assess the orientation and functionality of specific key molecular features. Here we present a method for the rapid screening of exposed protein recognition motifs on the surface of nanoparticles exploiting quartz crystal microbalance (QCM). We quantify accessible functional epitopes of transferrin-coated nanoparticles and correlate them to differences in nanoparticle size and functionalization. The target recognition occurs label free in flow, thereby pushing our investigation into a more in vivo-like scenario. Our method is applicable to a wide array of nanoparticles and therefore holds the potential to become an advanced technique for the classification of all kinds of nanobioconstructs based on their biological external functionality.

RESUMO

Background and Objectives: Data on the seroprevalence of viral hepatitis are limited in Haiti; consequently, the epidemiology is poorly described. This study aims to provide a descriptive analysis of hepatitis B virus (HBV) and hepatitis C virus (HCV) seroprevalence of blood donations in Haiti. Materials and Methods: Using Haiti's National Blood Safety Program and Haitian Red Cross reports from 2005 to 2014, we analysed the results of screening tests of donor serum samples to assess HBV and HCV seroprevalence among adults aged 17 to 65 years. Results: A total of 198 758 donor samples were screened from 2005 to 2014, of which 0·56% were positive for antibody to hepatitis C virus (anti-HCV) and 3·80% were positive for hepatitis B surface antigen. Over the 10-year study period, anti-HCV seroprevalence among blood donors increased by 31% from 0.66% to 0.86% (95% CI: 1·01-1·70); however, this trend was not uniform over time, with a significant decrease from 0·66% in 2005 to 0·39% in 2009 (95% CI: 0·43- 0·82) and 0·43% in 2012 (95% CI: 0·50-0·90). Conversely, HBV decreased significantly by 13% from 3·95% in 2005 to 3·42% in 2014 (95% CI: 0·77-0·97), a trend that was also observed in 2012 and 2013. Conclusion: The significant, uniform decrease in HBV seroprevalence in more recent years may represent the positive impact of public health interventions in preventing the transmission of blood-borne infections. More research is needed to understand why the trends in HCV transmission are non-uniform and to investigate the significant increase in more recent years.

RESUMO

BACKGROUND: The January 2010 Haiti earthquake destroyed the National Blood Transfusion Center and reduced monthly national blood collections by > 46%. Efforts to rapidly scale-up blood collections outside of the earthquake-affected region were investigated. STUDY DESIGN AND METHODS: Blood collection data for 2004-2014 from Haiti's 10 administrative departments were grouped into four regions: Northern, Central, Port-au-Prince and Southern. Analyses compared regional collection totals during the study period. RESULTS: Collections in Port-au-Prince accounted for 52% of Haiti's blood supply in 2009, but fell 96% in February 2010. Haiti subsequently increased blood collections in the North, Central and Southern regions to compensate. By May 2010, national blood collections were only 10·9% lower than in May 2009, with 70% of collections coming from outside of Port-au-Prince. By 2013 national collections (27 478 units) had surpassed 2009 levels by 30%, and Port-au-Prince collections had recovered (from 11 074 units in 2009 to 11 670 units in 2013). CONCLUSION: Haiti's National Blood Safety Program managed a rapid expansion of collections outside of Port-au-Prince following the earthquake. Annual collections exceeded pre-earthquake levels by 2012 and continued rising annually. Increased regional collections provided a greater share of the national blood supply, reducing dependence on Port-au-Prince for collections.

RESUMO

The range of possible nanostructures is so large and continuously growing, that collating and unifying the knowledge connected to them, including their biological activity, is a major challenge. Here we discuss a concept that is based on the connection of microscopic features of the nanomaterials to their biological impacts. We also consider what would be necessary to identify the features that control their biological interactions, and make them resemble each other in a biological context.

RESUMO

Localized rectal adenocarcinoma is a heterogeneous disease and current treatment recommendations are based on a preoperative multidisciplinary evaluation. High-resolution magnetic resonance imaging and endoscopic ultrasound are complementary to do a locoregional accurate staging. Surgery remains the mainstay of treatment and preoperative therapies with chemoradiation (CRT) or short-course radiation (SCRT) must be considered in more locally advanced cases. Novel strategies with induction chemotherapy alone or preceding or after CRT (SCRT) and surgery are in development.

RESUMO

Objetivo: El presente artículo describe el tratamiento multidisciplinario de un niño de 5 años de edad con desnutrición, alimentación selectiva, inapetencia e hiperrespuesta a los estí- mulos orales y táctiles. Se utilizó una intervención basada en una estrecha colaboración entre un pediatra, una dietetistanutricionista y una terapeuta ocupacional para afrontar el problema de alimentación. Se presenta una descripción de los 4 meses y medio de tratamiento y 2 meses de seguimiento. Método: Se analizaron las entrevistas con la familia y las notas de evolución en pediatría, nutrición y terapia ocupacional. Se presenta la progresión hacia los objetivos nutricionales, de aceptación de alimentos y de participación activa en el proceso de alimentación. Resultados: La normalización del estado nutricional se documenta mediante el seguimiento del índice de masa corporal y de datos antropométricos por parte del pediatra y de la nutricionista. La mejora en la participación en las comidas y en la aceptación de una mayor cantidad y variedad de alimentos se documenta mediante entrevistas con los padres y observaciones directas en las sesiones de terapia ocupacional. La mejora en las respuestas al estímulo oral y táctil se documenta mediante un cuestionario estandarizado (Sensory Profile). Conclusión: Este caso clínico contribuye a la evidencia existente sobre la utilización de un enfoque multidisciplinario en los casos de niños con desnutrición y rechazo a la alimentación. La consideración de problemas sensoriales como factor subyacente al problema de alimentación ha sido clave en la mejoría nutricional de este niño. Asimismo, este caso clínico contribuye a la evidencia sobre el uso de la terapia ocupacional basada en el enfoque de la integración sensorial de la Dra. Ayres para abordar la relación entre el procesamiento sensorial, la conducta y el desempeño ocupacional (AU)


Objective: This article describes the multidisciplinary treatment of a 5 year old child with malnutrition, selective feeding, lack of appetite and sensory over-responsiveness to oral and tactile stimuli. An intervention based on a close collaboration between a pediatrician, a dietician-nutritionist and an occupational therapist was used to treat the feeding problem. A description of the 4 and half months of treatment and a 2 month follow-up is presented. Methods: Interviews with the family and pediatric, nutrition and occupational therapy progress notes are analyzed. Progress towards nutritional objectives, acceptance of food and active participation in the feeding process is presented. Results: The normalization of the nutritional status is documented through monitoring of body mass and anthropometric data by the pediatrician and nutritionist. Improvement in meal participation and acceptance of a greater amount and variety of foods is documented through interviews with parents and direct observations in the occupational therapy sessions. The improvement in oral and tactile sensory reactivity is documented using a standardized questionnaire (Sensory Profile). Conclusion: This clinical case report contributes to the existing evidence on the use of a multidisciplinary approach in the treatment of children with malnutrition and refusal to feed. Consideration of sensory issues as an underlying factor to the feeding problem has been instrumental in the nutritional improvement of this child. This clinical case also contributes to the evidence on the use of occupational therapy based on Dr. Ayres sensory integration approach in addressing the relationship between (AU)

RESUMO

We present the main features of CITIUS, a new light source for ultrafast science, generating tunable, intense, femtosecond pulses in the spectral range from infrared to extreme ultraviolet (XUV). The XUV pulses (about 10(5)-10(8) photons/pulse in the range 14-80 eV) are produced by laser-induced high-order harmonic generation in gas. This radiation is monochromatized by a time-preserving monochromator, also allowing one to work with high-resolution bandwidth selection. The tunable IR-UV pulses (10(12)-10(15) photons/pulse in the range 0.4-5.6 eV) are generated by an optical parametric amplifier, which is driven by a fraction of the same laser pulse that generates high order harmonics. The IR-UV and XUV pulses follow different optical paths and are eventually recombined on the sample for pump-probe experiments. We also present the results of two pump-probe experiments: with the first one, we fully characterized the temporal duration of harmonic pulses in the time-preserving configuration; with the second one, we demonstrated the possibility of using CITIUS for selective investigation of the ultra-fast dynamics of different elements in a magnetic compound.

RESUMO

Objetivo. Conocer la satisfacción de los profesionales (enfermería/medicina) que participaban en un proyecto de telemonitorización, desde la atención primaria, de pacientes con enfermedades crónicas (insuficiencia cardiaca y/o broncopatía), con varios ingresos hospitalarios y dificultad para salir de sus domicilios (proyecto TELBIL-A). Material y métodos. En noviembre de 2012 se remitió a los correos electrónicos de 55 sanitarios participantes un cuestionario Web (aplicación «encuesta fácil») diseñado por los investigadores. Constaba de 6 ítems para valorar satisfacción (escala de Likert de 1 —mayor desacuerdo, apreciación más negativa— a 5 —mayor acuerdo, apreciación más positiva—), edad, experiencia profesional y una pregunta abierta para comentarios. Los datos se descargaron y analizaron con el programa SPSS 18.0. Resultados. La tasa de respuesta fue de 90,9% (50 respuestas), 94% de mujeres, un 68% >= 40 años y un 90% > 5 años de experiencia trabajando en el centro de salud. Un 86% eligió la respuesta 4 o 5 en el ítem de satisfacción general con el proyecto, siendo la puntuación media de 4,4 puntos. La media para el resto de preguntas fue de: 3,8 para la interferencia con las tareas habituales, 4,5 en apreciar ventajas en el manejo de los pacientes, 4,2 en la sensación de que los pacientes participaban más en su autocuidado, 3,9 en el aspecto tecnológico y 4,3 en recomendarlo potencialmente a un amigo/familiar. Conclusiones. En las condiciones del estudio se observa una elevada satisfacción con el proyecto TELBIL-A por parte de los profesionales que están participando en el mismo (AU)


Objective: To analyze, through an on-line survey, the satisfaction of professionals (nurses/ general practitioners) taking part in a project of telemonitoring in-home patients with chronic diseases (heart failure and/or pulmonary disease) with ≥2 hospital admissions in the last year (TELBIL-A project). Material and methods: An on-line questionnaire designed by the researchers (using «easy survey» application) was sent to professionals’ email. It consisted of several items to assess satisfaction (Likert scale from 1-strongly disagree, negative appreciation- to 5- strongly agree, positive appreciation-), age, number of years working in Primary Care, and an open question for comments. Data were analyzed using SPSS 18.0. Results: We received responses from 50 out of 55 professionals (90.9%), of whom 94% were female, and 68% aged >=40 years, with 90% working > 5 years in Primary Care. They chose in 86% answer 4 or 5 for the item on overall satisfaction with the project, with the average score being 4.4. The means for the rest of questions were: 3.8 for interference with other professional daily tasks, 4.5 appreciating advantages in the management of patients, 4.2 for the feeling that patients are more involved in their own care, 3.9 for technological aspects, and 4.3 for recommending to a friend/relative. Conclusions: The study explores one aspect, satisfaction with the project, which is critical because of the association with the correct compliance and developing of the intervention. We found a high satisfaction of professionals involved with the TELBIL-A project (AU)
