Personalized monitoring of circulating tumor DNA with a specific signature of trackable mutations after chimeric antigen receptor T-cell therapy in follicular lymphoma patients.

Background: CART therapy has produced a paradigm shift in the treatment of relapsing FL patients. Strategies to optimize disease surveillance after these therapies are increasingly necessary. This study explores the potential value of ctDNA monitoring with an innovative signature of personalized trackable mutations. Method: Eleven FL patients treated with anti-CD19 CAR T-cell therapy were included. One did not respond and was excluded. Genomic profiling was performed before starting lymphodepleting chemotherapy to identify somatic mutations suitable for LiqBio-MRD monitoring. The dynamics of the baseline mutations (4.5 per patient) were further analyzed on 59 cfDNA follow-up samples. PET/CT examinations were performed on days +90, +180, +365, and every six months until disease progression or death. Results: After a median follow-up of 36 months, all patients achieved a CR as the best response. Two patients progressed. The most frequently mutated genes were CREBBP, KMT2D and EP300. Simultaneous analysis of ctDNA and PET/CT was available for 18 time-points. When PET/CT was positive, two out of four ctDNA samples were LiqBio-MRD negative. These two negative samples corresponded to women with a unique mesenteric mass in two evaluations and never relapsed. Meanwhile, 14 PET/CT negative images were mutation-free based on our LiqBio-MRD analysis (100%). None of the patients had a negative LiqBio-MRD test by day +7. Interestingly, all durably responding patients had undetectable ctDNA at or around three months after infusion. Two patients presented discordant results by PET/CT and ctDNA levels. No progression was confirmed in these cases. All the progressing patients were LiqBio-MRD positive before progression. Conclusion: This is a proof-of-principle for using ctDNA to monitor response to CAR T-cell therapy in FL. Our results confirm that a non-invasive liquid biopsy MRD analysis may correlate with response and could be used to monitor response. Harmonized definitions of ctDNA molecular response and pinpointing the optimal timing for assessing ctDNA responses are necessary for this setting. If using ctDNA analysis, we suggest restricting follow-up PET/CT in CR patients to a clinical suspicion of relapse, to avoid false-positive results.

Real-life disease monitoring in follicular lymphoma patients using liquid biopsy ultra-deep sequencing and PET/CT.

In the present study, we screened 84 Follicular Lymphoma patients for somatic mutations suitable as liquid biopsy MRD biomarkers using a targeted next-generation sequencing (NGS) panel. We found trackable mutations in 95% of the lymph node samples and 80% of the liquid biopsy baseline samples. Then, we used an ultra-deep sequencing approach with 2 · 10-4 sensitivity (LiqBio-MRD) to track those mutations on 151 follow-up liquid biopsy samples from 54 treated patients. Positive LiqBio-MRD at first-line therapy correlated with a higher risk of progression both at the interim evaluation (HRINT 11.0, 95% CI 2.10-57.7, p = 0.005) and at the end of treatment (HREOT, HR 19.1, 95% CI 4.10-89.4, p < 0.001). Similar results were observed by PET/CT Deauville score, with a median PFS of 19 months vs. NR (p < 0.001) at the interim and 13 months vs. NR (p < 0.001) at EOT. LiqBio-MRD and PET/CT combined identified the patients that progressed in less than two years with 88% sensitivity and 100% specificity. Our results demonstrate that LiqBio-MRD is a robust and non-invasive approach, complementary to metabolic imaging, for identifying FL patients at high risk of failure during the treatment and should be considered in future response-adapted clinical trials.

Transcriptomic clustering of critically ill COVID-19 patients.

BACKGROUND: Infections caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may cause a severe disease, termed coronavirus disease 2019 (COVID-19), with significant mortality. Host responses to this infection, mainly in terms of systemic inflammation, have emerged as key pathogenetic mechanisms and their modulation has shown a mortality benefit. METHODS: In a cohort of 56 critically ill COVID-19 patients, peripheral blood transcriptomes were obtained at admission to an intensive care unit (ICU) and clustered using an unsupervised algorithm. Differences in gene expression, circulating microRNAs (c-miRNAs) and clinical data between clusters were assessed, and circulating cell populations estimated from sequencing data. A transcriptomic signature was defined and applied to an external cohort to validate the findings. RESULTS: We identified two transcriptomic clusters characterised by expression of either interferon-related or immune checkpoint genes, respectively. Steroids have cluster-specific effects, decreasing lymphocyte activation in the former but promoting B-cell activation in the latter. These profiles have different ICU outcomes, despite no major clinical differences at ICU admission. A transcriptomic signature was used to identify these clusters in two external validation cohorts (with 50 and 60 patients), yielding similar results. CONCLUSIONS: These results reveal different underlying pathogenetic mechanisms and illustrate the potential of transcriptomics to identify patient endotypes in severe COVID-19 with the aim to ultimately personalise their therapies.

Structural brain changes in patients with persistent headache after COVID-19 resolution.

Headache is among the most frequently reported symptoms after resolution of COVID-19. We assessed structural brain changes using T1- and diffusion-weighted MRI processed data from 167 subjects: 40 patients who recovered from COVID-19 but suffered from persistent headache without prior history of headache (COV), 41 healthy controls, 43 patients with episodic migraine and 43 patients with chronic migraine. To evaluate gray matter and white matter changes, morphometry parameters and diffusion tensor imaging-based measures were employed, respectively. COV patients showed significant lower cortical gray matter volume and cortical thickness than healthy subjects (p < 0.05, false discovery rate corrected) in the inferior frontal and the fusiform cortex. Lower fractional anisotropy and higher radial diffusivity (p < 0.05, family-wise error corrected) were observed in COV patients compared to controls, mainly in the corpus callosum and left hemisphere. COV patients showed higher cortical volume and thickness than migraine patients in the cingulate and frontal gyri, paracentral lobule and superior temporal sulcus, lower volume in subcortical regions and lower curvature in the precuneus and cuneus. Lower diffusion metric values in COV patients compared to migraine were identified prominently in the right hemisphere. COV patients present diverse changes in the white matter and gray matter structure. White matter changes seem to be associated with impairment of fiber bundles. Besides, the gray matter changes and other white matter modifications such as axonal integrity loss seemed subtle and less pronounced than those detected in migraine, showing that persistent headache after COVID-19 resolution could be an intermediate state between normality and migraine.

Results in clinical practice in the treatment of severe eosinophilic asthma with mepolizumab: a real-life study.

OBJECTIVE: Add-on therapy with monoclonal antibodies is the recommended therapy for severe asthmatic patients refractory to maintenance treatment. In randomized control trials, mepolizumab reduced the number of exacerbations, the need of oral corticosteroids (OCS), increased asthma control, and lung function in a population of uncontrolled severe eosinophilic asthmatic patients. In this piece of work, we aimed to assess mepolizumab efficacy and safety in a cohort of patients with severe eosinophilic asthma in real-life conditions. METHODS: A retrospective study was carried out at eight hospitals from Asturias (Spain). The sample included patients treated with mepolizumab from 1 January 2016 to 31 March 2019. Demographic and clinical variables were collected, including OCS use, asthma control, lung function, and exacerbation rate. RESULTS: Sixty-nine patients (72% women) with mean age 56 ± 13 years were included. Annual exacerbation rate decreased from 4.7 (SD 3.7) to 1.3 (SD 2.5) (p < 0.001). The number of patients requiring OCS treatment decreased from 25 patients (36%, mean prednisone dose = 18 mg/day) to 13 patients (19%, mean prednisone dose = 9 mg/day) (p < 0.001). Twelve patients (48%) stopped OCS treatment. Forced expired volume in one second (FEV1) as percentage increased from 68% (SD 20) to 76% (SD 21) (p < 0.001). Fifty-six patients (81%) were considered responders to mepolizumab. No serious adverse events were detected during the study period. CONCLUSIONS: Overall, this study demonstrates mepolizumab efficacy and safety in a cohort of patients with uncontrolled severe eosinophilic asthma in routine clinical practice.

Compulsive buying behavior of Smartphones by university students.

BACKGROUND: Few studies have analyzed compulsive buying behavior in relation to a specific product. Smartphones are hugely popular products today, especially among young people. These two aspects have motivated this research into the compulsive buying behavior of Smartphones by university students. METHODS: To study this behavior, the main features that differentiate compulsive buyers from those that are not are analyzed, and their risk profiles are obtained through a discrete choice model. RESULTS: Sociodemographic features that define buyers with the greatest propensity to compulsiveness are younger age, longer time spent daily using social networks, higher spending on the acquisition of Smartphones and having owned a greater number of these devices. These buyers also show shopping addiction and greater feelings of guilt after the purchase as well as more positive and negative affective states when purchasing Smartphones. CONCLUSIONS: This analysis not only determines the characteristics that define young individuals with a tendency toward compulsiveness in Smartphone purchases, but also contributes to quantifying the probability of having this tendency.

Falsos positivos del cribado de trisomía 21 y 18 del primer trimestre y complicaciones obstétricas / Adverse outcomes in pregnancies with false positive trisomy 21 and 18 screening results

OBJETIVO: Analizar si los casos positivos de cribado combinado de trisomía 21 (t21) o trisomía 18 (t18) en ausencia de aneuploidía (falsos positivos- FP) se relacionan con complicaciones de la gestación, ajustando por factores demográficos y clínicos de riesgo. MATERIAL Y MÉTODOS: Estudio retrospectivo de casos y controles anidado en una cohorte de pacientes que acudieron para cribado del primer trimestre. Los casos fueron las pacientes con FP de riesgo combinado de t21 superior a 1/270 o riesgo de t18 superior a 1/100. Se consideraron complicaciones de la gestación: óbito fetal, parto prematuro menor de 34 semanas o prematuro menor de 37 semanas, preeclampsia, retrasos de crecimiento, pequeño para la edad gestacional (CIR, PEG) y diabetes gestacional (DG). Se ajustó por obesidad, edad, paridad, tabaquismo, y técnicas de reproducción asistida. RESULTADO: Se obtuvieron 204 casos de FP, 149 FP para trisomía 21, 41 para trisomía 18, y 14 FP para ambos riesgos. Se encontró asociación estadísticamente significativa de FP t21 con óbito fetal (OR=3,5; ic95% 1,4-8,7; p=0,01), parto prematuro menor de 37 semanas (OR=2,2; IC95% 1,4-3,4; p=0,001), preeclampsia (OR =2,6; IC95% 1,17-6,1; p=0,02), PEG (OR =2,2; IC95% 1,2-4,1; p=0,02), CIR (OR=2,8; IC95% 1,6-5,1; p=0,001), y DG (OR=2,1; IC95% 1,2-3,7; p=0,01). Los FP t18 se asociaron con óbito (OR=8,9; IC95% 2,9-27; p=0,002). CONCLUSIÓN: Los FP del cribado del primer trimestre, para trisomía 21 y trisomía 18, se asocian con resultados obstétricos adversos.

We have studied whether positive cases of combined trisomy 21 (t21) or 18 (t18) screening in the absence of aneuploidy (false positives -FP-) are related to pregnancy complications adjusting for demographic and clinical risk factors. METHODS: Retrospective case-control study nested in a cohort of patients who came for first trimester aneuploidy screening. The cases were patients with FP combined risk of t21 (greater than 1/270) or t18 risk (greater than 1/100). The control group was a sample of patients with low-risk screening. We considered pregnancy complications: stillbirth, premature delivery before 34 and 37 weeks, preeclampsia, growth retardation, small for gestational age (FGR, SGA), and gestational diabetes (GD). Or were adjusted for obesity, age, parity, smoking, and assisted reproduction techniques. RESULTS: 204 cases of FP were obtained, 149 FP for trisomy 21, 41 for trisomy 18, and 14 FP for both risks. A statistically significant association between t21 FP was found with stillbirth (OR = 3.5; 95% CI 1.4-8.7; p = 0.01), preterm delivery less than 37 weeks (OR = 2.2; 95% CI 1.4-3.4; p = 0.001), preeclampsia (OR = 2.6; 95% CI 1.17-6.1; p = 0.02), SGA (OR = 2.2; 95% CI 1, 2-4.1; p = 0.02), FGR (OR = 2.8; 95% CI 1.6-5.1; p = 0.001), and GD (OR = 2.1; 95% CI 1.2 −3.7; p = 0.01). FP t18s were associated with fetal loss (OR= 8.9 (95% CI 2.9-27) p = 0.002. CONCLUSION: FP from first trimester screening for t21 and t18 are associated with adverse obstetric outcomes.

In-vivo measurement of the fluorescence spectrum of wild cochineal (Dactylopius opuntiae).

It is known that the harmful presence of the wild cochineal (Dactylopius opuntiae), unlike the fine cochineal (Dactylopius coccus), in prickly pear crops of farmers leads to consider it as one of the major pests for this crop. In this study, we present the implementation of an optical setup that ensures the measurement of the in-vivo fluorescence spectra of wild cochineals ranging in size from 440 to 1190 µm in their natural habitat achieved by developing a reproduction model adopted from available literature. It was observed that in-vivo fluorescence spectra of these insects were comprised in the spectral region of 570-760 nm, showing a proportional dependence between the fluorescence intensity emitted and the cochineal size. In addition, we have considered other spectral parameters to perform the comparison between fluorescence spectra of the different cochineal sizes. These results provide the basis for the development of novel methodologies and equipment aimed towards the early detection of this pest in prickly pear crops from its early growth stages (nymph I and II).

El papel de hospitales municipales y provinciales en España desde una perspectiva histórica / The role of municipal and provincial hospitals in Spain from a historical perspective

Los hospitales municipales y provinciales representaron un papel clave en la confi-guración histórica del sistema hospitalario en España hasta la segunda mitad del siglo XX. Su papel estratégico en la beneficencia del siglo XIX para la cobertura de los pobres se modificó con el avance y la configuración del hospital moderno ubicado en nuevos edificios y técnicas de gestión, con una estructura interna jerarquizada y avances en ámbito diagnóstico-terapéutico para la cobertura de cada vez más porcentaje de población. Partiendo de esta idea, este trabajo se centra en el estudio histórico de las infraestructuras hospitalarias públicas vinculadas a los municipios y diputaciones en España con dos objetivos. De un lado, trata de analizar cómo se configuraron, qué servicios prestaron y cómo afrontaron su financiación hasta la dictadura de Franco. De otro, aborda los efectos que tuvo la puesta en marcha del Seguro Obligatorio de Enfermedad (SOE), en 1944, y la construcción de su propia red de hospitales, conocidos como residencias sanitarias, en el funcionamiento y supervivencia de estas viejas infraestructuras municipales y provinciales. Finalmente se analiza su práctica desaparición tras la cesión de las competencias sanitarias en la transición democrática (AU)

Delirium en una unidad de cuidados paliativos: incidencia y factores de riesgo asociados / Delirium in a palliative care unit: incidence and associated risk factors

INTRODUCCIÓN: El delirium es un trastorno neuropsiquiátrico muy frecuente en pacientes ingresados en unidades de cuidados paliativos. OBJETIVOS: Estudiar la incidencia de delirium en una población de pacientes ingresados en una unidad de cuidados paliativos (UCP); analizar los posibles factores sociodemográficos, clínicos, funcionales y mentales que pudieran asociarse al riesgo de delirium. MATERIAL Y MÉTODOS: Estudio epidemiológico longitudinal sobre una población de pacientes hospitalizados en la UCP entre el 13 de marzo y el 13 de abril de 2019. Se recogieron variables sociodemográficas, clínicas, funcionales (índice de Barthel y Karnofsky) y mentales (Global Deterioration Scale). El diagnóstico de delirium se realizó en base al Confussional Assessment Method (CAM) y se clasificó en hiperactivo, hipoactivo y mixto. RESULTADOS: 35 sujetos fueron incluidos en el estudio (77,69 ± 11,66 años; 51,4 % mujeres; Barthel 35,14 ± 31,54 y Karnofsky 30 ± 19,40). Se detectó una incidencia de delirium del 65,7 % (11,4 % hiperactivo, 20,4 % hipoactivo y 34,3 % mixto). Se objetivó asociación estadística con delirium de: puntuación en el Barthel y Karnofsky, presencia de metástasis cerebrales y ser tratados con antidepresivos. CONCLUSIONES: Para nuestra población de estudio, el 65,7 % de los sujetos ingresados en la UCP desarrolla un delirium. Según los resultados obtenidos, la puntuación en Barthel y el Karnofsky, así como la existencia de metástasis cerebrales y la prescripción de antidepresivos, son factores que se asocian a un aumento del riesgo de sufrir delirium

INTRODUCTION: Delirium is a very common neuropsychiatric disorder in patients admitted to palliative care units. OBJECTIVES: To study the incidence of delirium in a population of patients admitted to a Palliative Care Unit (PCU); to analyze the sociodemographic, clinical, functional, and mental factors associated with the risk of delirium. MATERIAL AND METHODS: A longitudinal epidemiological study in a population of patients hospitalized in the PCU between March 13 and April 13, 2019. Sociodemographic, clinical, functional (Barthel and Karnofsky Index), and mental variables were collected (Global Deterioration Scale). The diagnosis of delirium was made based on the Confussional Assessment Method (CAM), and was then classified as hyperactive, hypoactive, or mixed. RESULTS: A total of 35 subjects were included in the study (77.69 ± 11.66 years, 51.4 % women, Barthel: 35.14 ± 31.54, Karnofsky: 30 ± 19.40). The incidence of delirium was 65.7 % (11.4 % hyperactive, 20.4 % hypoactive, 34.3 % mixed). A statistical association with delirium was observed for: Barthel and Karnofsky scores, presence of brain metastases, and treatment with antidepressants. CONCLUSIONS: In all, 65.7 % of the subjects admitted to the PCU developed delirium. Barthel and Karnofsky scores, as well as the existence of brain metastases and the prescription of antidepressants were factors associated with the risk of delirium

Gray Matter Structural Alterations in Chronic and Episodic Migraine: A Morphometric Magnetic Resonance Imaging Study.

OBJECTIVE: This study evaluates different parameters describing the gray matter structure to analyze differences between healthy controls, patients with episodic migraine, and patients with chronic migraine. DESIGN: Cohort study. SETTING: Spanish community. SUBJECTS: Fifty-two healthy controls, 57 episodic migraine patients, and 57 chronic migraine patients were included in the study and underwent T1-weighted magnetic resonance imaging acquisition. METHODS: Eighty-four cortical and subcortical gray matter regions were extracted, and gray matter volume, cortical curvature, thickness, and surface area values were computed (where applicable). Correlation analysis between clinical features and structural parameters was performed. RESULTS: Statistically significant differences were found between all three groups, generally consisting of increases in cortical curvature and decreases in gray matter volume, cortical thickness, and surface area in migraineurs with respect to healthy controls. Furthermore, differences were also found between chronic and episodic migraine. Significant correlations were found between duration of migraine history and several structural parameters. CONCLUSIONS: Migraine is associated with structural alterations in widespread gray matter regions of the brain. Moreover, the results suggest that the pattern of differences between healthy controls and episodic migraine patients is qualitatively different from that occurring between episodic and chronic migraine patients.

Alternative Microstructural Measures to Complement Diffusion Tensor Imaging in Migraine Studies with Standard MRI Acquisition.

The white matter state in migraine has been investigated using diffusion tensor imaging (DTI) measures, but results using this technique are conflicting. To overcome DTI measures, we employed ensemble average diffusion propagator measures obtained with apparent measures using reduced acquisitions (AMURA). The AMURA measures were return-to-axis (RTAP), return-to-origin (RTOP) and return-to-plane probabilities (RTPP). Tract-based spatial statistics was used to compare fractional anisotropy, mean diffusivity, axial diffusivity and radial diffusivity from DTI, and RTAP, RTOP and RTPP, between healthy controls, episodic migraine and chronic migraine patients. Fifty healthy controls, 54 patients with episodic migraine and 56 with chronic migraine were assessed. Significant differences were found between both types of migraine, with lower axial diffusivity values in 38 white matter regions and higher RTOP values in the middle cerebellar peduncle in patients with a chronic migraine (p < 0.05 family-wise error corrected). Significantly lower RTPP values were found in episodic migraine patients compared to healthy controls in 24 white matter regions (p < 0.05 family-wise error corrected), finding no significant differences using DTI measures. The white matter microstructure is altered in a migraine, and in chronic compared to episodic migraine. AMURA can provide additional results with respect to DTI to uncover white matter alterations in migraine.

Perfil del paciente que sufre caídas en el entorno hospitalario: estudio multicéntrico / Profile of the patient who suffers falls in the hospital environment: Multicenter study

OBJETIVOS: Analizar el perfil de los pacientes que sufren caídas en el entorno hospitalario. MÉTODO: Estudio longitudinal, de seguimiento prospectivo de una cohorte de pacientes reclutada de mayo de 2014 a marzo de 2016. Participaron 5 hospitales de agudos de la Comunidad de Andalucía de unidades médicas, quirúrgicas y cuidados intensivos. Se incluyeron pacientes mayores de 16 años. Las variables de caracterización fueron: edad, sexo, unidad, estancia, medidas preventivas; y las de resultado: nivel de conciencia, déficits sensoriales, movilidad, número de caídas, circunstancias y consecuencias, medicamentos, caídas previas. RESULTADOS: Se reclutaron 1.247 pacientes, de los que 977 completaron el estudio. La incidencia de caídas fue del 2,35%. La edad media de las personas que sufrieron caídas fue de 73,6 años (p = 0,015). El evento aconteció sobre todo en las mujeres (56,5%) y en las unidades médicas (79%). Las caídas ocasionaron daños menores. La reordenación del mobiliario demostró ser la única medida protectora (OR=3,95; IC95% 1,46-10,68; p = 0,015). Los factores predictivos del suceso fueron: haber ingresado en el hospital tras una caída (HR=5,88; IC95% 3,23-10,67; p < 0,001), seguido de problemas visuales, ir al baño con frecuencia y haber sufrido caídas previas. CONCLUSIONES: El perfil del paciente que sufre caídas en el hospital se presenta como mayor de 70 años, mujer, ingresada en una unidad médica, durante el turno de noche, estando en cama y solo, sin deterioro del nivel de conciencia y con antecedentes de caídas

AIMS: To analyse the profile of patients suffering from falls in the hospital environment. METHOD: Longitudinal study, prospective follow-up of a cohort of patients recruited from May 2014 to March 2016. Medical, surgical and intensive care units of 5 acute hospitals of the Community of Andalusia participated. Patients older than 16 years were included. The variables of characterization were: age, sex, unit, stay, preventive measures, and those of result: level of consciousness, sensory deficits, mobility, number of falls, circumstances and consequences, medications, previous falls. RESULTS: 1,247 patients were recruited, of whom 977 completed the study. The incidence of falls was 2.35%. The average age of the faller was 73.6 years (P=.015). The event occurred mostly in women (56.5%) and in medical units (79%). The falls caused minor damage. Rearrangement of the furniture proved to be the only protective measure (OR= 3.95, 95% CI 1.46-10.68, P=.015). The predictors of the event were: having been admitted to the hospital after a fall (HR= 5.88, 95% CI 3.23-10.67, P<.001), followed by visual problems, frequent visits to the bathroom and having suffered previous falls. CONCLUSIONS: The profile of the patient suffering falls in the hospital is presented as aged over 70 years old, female, admitted to a medical unit, during the night shift, being in bed and alone, without impaired level of consciousness and with a history of falls
