EVALUATION OF THE TRANSITION FROM INTRAVENOUS TO SUBCUTANEOUS VEDOLIZUMAB IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE. / VALORACIÓN DE LA TRANSICIÓN DE VEDOLIZUMAB INTRAVENOSO A SUBCUTÁNEO EN PACIENTES CON ENFERMEDAD INFLAMATORIA INTESTINAL.

AIMS: The aim of the study is to evaluate the clinical and biochemical response of inflammatory bowel disease (IBD) patients treated with vedolizumab, 16 weeks after transitioning from intravenous (iv) to subcutaneous (sc). METHODS: An observational, prospective, single-center cohort study was performed. Patients with IBD and maintenance treatment with vedolizumab, stable for at least 4 months, were offered to switch to sc formulation. At the same time of treatment administration a blood test was performed, with vedolizumab levels and fecal calprotectin. RESULTS: 43 patients were included, 12 of them (27.9%) chose to transition to sc formulation. All included patients remained in remission during follow-up. At week 16 (w16), no significant differences were found in terms of calprotectin levels in patients on iv treatment (mean 146.6 ± SD 45.9) vs sc (159.26 ± 53.9) (p 0.9). Vedolizumab serum levels at w16 were higher in the sc group (22364.3 ± 5141.6) vs. iv (11425.9 ± 1514.2) (p 0.009). At w16, 9 (75%) of the patients in the SC group were highly satisfied with the medication and 11 (91.7%) considered it easy to administer. 4 patients (12.9%) in the iv group and 2 (16.6%) in the sc group presented mild adverse effects. The 2 cases (100%) of the sc group the adverse event was local inflammation at the injection site. CONCLUSION: In our experience, vedolizumab sc is a convenient alternative to iv administration. Vedolizumab serum levels in patients who transitioned to sc were higher than iv formulation.

Equipo multidisciplinar de cirugía radioguiada: Alternativa de cambio al paradigma actual / Multidisciplinary radio-guided surgery team: Alternative to change the current paradigm

IntroducciónAnte el aumento constante de la demanda asistencial de exploraciones relacionadas con cirugía radioguiada (CRG), nuestro hospital adoptó incluir en el equipo de CRG nuevos perfiles profesionales con el fin de reducir parcialmente el tiempo de dedicación de los médicos nucleares a esta tarea.Objetivos: Analizar el proceso de incorporación de los perfiles de Técnico Superior en Imagen para el Diagnóstico (TSID) y Enfermera Referente de Ganglio Centinela (ERGC), evaluando su despliegue en los procedimientos ligados a la técnica. Material y métodos: Análisis de la actividad de CRG durante el periodo 2018-2022, centrándolo en los procedimientos prequirúrgicos y quirúrgicos relativos a cáncer de mama (CaM) y melanoma maligno (MM), por ser aquellas patologías en las que se concentró la transferencia de competencias asistenciales. Evolución cronológica de las competencias asumidas por los diferentes perfiles durante su integración en el equipo de CRG. Resultados: La actividad asistencial de CRG durante el periodo analizado experimentó un incremento del 109%. CaM y MM son las patologías que aglutinaron con diferencia una mayor demanda asistencial. La transferencia de competencias en estas dos patologías se ha producido de manera progresiva, asumiendo en 2022 el 74% (460/622) de la fase de administración el ERGC y el 64% (333/519) de las cirugías el TSID. Conclusiones: La creación de un equipo multidisciplinar de CRG, que incluye distintos perfiles profesionales (MN, ERGC y TSID), es una eficaz estrategia para dar respuesta al incremento de la complejidad y número de todos los procedimientos relacionados con la CRG.(AU)

Introduction: Given the constant increase in the healthcare demand for examinations related to radio-guided surgery (RGS), our hospital adopted new professional profiles in the RGS team, in order to partially reduce the time spent by nuclear medicine physicians on this task. Aim: To analyze the process of incorporating the profiles of Superior Diagnostic Imaging Technician (TSID) and Sentinel Node Referent Nurse (ERGC), evaluating their deployment in the procedures linked to the technique. Material and methods: Analysis of RGS activity during the period 2018-2022, focusing on pre-surgical and surgical procedures related to breast cancer (BC) and malignant melanoma (MM), as they are those pathologies on which the transfer of care competencies was concentrated. Chronological evolution of the competencies assumed by the different profiles during their integration into the RGS team. Results: RGS's healthcare activity during the analyzed period experienced an increase of 109%. BC and MM were the pathologies that accounted for by far the greatest demand for care. The transfer of competencies in these two pathologies occurred in a progressive and staggered manner, with 74% (460/622) of the administration phase being carried out by the ERGC and 64% (333/519) of the surgeries by the TSID in 2022. Conclusions: The creation of a multidisciplinary RGS team that includes different professional profiles (NM, ERGC and TSID) is an effective strategy to respond to the increase in the complexity and number of all procedures related to RGS.(AU)

Seroprevalence of ANTI-SARS-CoV-2 antibodies in patients with inflammatory bowel disease.

Patients with inflammatory bowel disease (IBD) treated with biologic and/or immunosuppressant drugs are at increased risk for opportunistic infections. Seroprevalence studies can confirm the diagnosis of SARS-CoV-2 infections as well as the associated risk factors. This is a descriptive study which primary endpoints were to highlight the prevalence of SARS-CoV-2 antibodies in a cohort of IBD patients in March 2021, and to analyze seroconversion in patients with known COVID-19 infection and its relationship with IBD treatments. Patients filled in a questionnaire about symptoms of COVID-19 infection and clinical information about their IBD. All included patients were tested for SARS-CoV-2 antibodies. 392 patients were included. Among patients with clinical infection, 69 patients (17,65%) were IgG-positive, 286 (73,15%) IgG-negative and 36 (9,21%) indeterminate. In relation to seroconversion among patients under biologic treatment, 13 patients of the 23 with a previous positive CRP developed antibodies (56.5%). However, when the influence of immunosuppressive treatment on the probability of developing antibodies was analyzed, no significant differences were seen between those patients with or without treatment (77.8% vs. 77.1%, p = 0.96). In our cohort of IBD patients, after one year of pandemic, there were 18.64% IgG positive patients, a higher prevalence than the general population (15.7%).

Particle size and cholesterol content of circulating HDL correlate with cardiovascular death in chronic heart failure.

Evidence regarding any association of HDL-particle (HDL-P) derangements and HDL-cholesterol content with cardiovascular (CV) death in chronic heart failure (HF) is lacking. To investigate the prognostic value of HDL-P size (HDL-Sz) and the number of cholesterol molecules per HDL-P for CV death in HF patients. Outpatient chronic HF patients were enrolled. Baseline HDL-P number, subfractions and HDL-Sz were measured using 1H-NMR spectroscopy. The HDL-C/P ratio was calculated as HDL-cholesterol over HDL-P. Endpoint was CV death, with non-CV death as the competing event. 422 patients were included and followed-up during a median of 4.1 (0-8) years. CV death occurred in 120 (30.5%) patients. Mean HDL-Sz was higher in CV dead as compared with survivors (8.39 nm vs. 8.31 nm, p < 0.001). This change in size was due to a reduction in the percentage of small HDL-P (54.6% vs. 60% for CV-death vs. alive; p < 0.001). HDL-C/P ratio was higher in the CV-death group (51.0 vs. 48.3, p < 0.001). HDL-Sz and HDL-C/P ratio were significantly associated with CV death after multivariable regression analysis (HR 1.22 [95% CI 1.01-1.47], p = 0.041 and HR 1.04 [95% CI 1.01-1.07], p = 0.008 respectively). HDL-Sz and HDL-C/P ratio are independent predictors of CV death in chronic HF patients.

Usefulness of intestinal ultrasound in inflammatory bowel disease. / Utilidad de la ecografía intestinal en la enfermedad inflamatoria intestinal.

Imaging techniques play a fundamental role in the initial diagnosis and follow-up of inflammatory bowel disease. Intestinal ultrasound has high sensitivity and specificity in patients with suspected Crohn's disease and in the detection of inflammatory activity. This technique enables the early diagnosis of intra-abdominal complications such as stenosis, fistulas, and abscesses. It has also proven useful in monitoring the response to treatment and in detecting postsurgical recurrence. Technical improvements in ultrasound scanners, technological advances such as ultrasound contrast agents and elastography, and above all increased experience have increased the role of ultrasound in the evaluation of the gastrointestinal tract. The features that make ultrasound especially attractive include its wide availability, its noninvasiveness and lack of ionizing radiation, its low cost, and its good reproducibility, which is important because it is easy to repeat the study and the study is well tolerated during follow-up. This review summarizes the role of intestinal ultrasound in the detection and follow-up of inflammatory bowel disease.

Influence of fertilisation with foliar urea on the content of amines in wine.

Amines are substances that could cause toxic effects in the consumer. The concentration of amines in wine depends on different factors such as grape variety, vinification conditions and nitrogen fertilisation of the vines. The aim of this work was to study the influence of the application of foliar urea on the concentration of amines in wine. To carry out the study, grapevines of Tempranillo variety were used. These grapevines were treated with foliar urea at two different concentrations: 2 and 4 kg N ha(-1). Treatment with foliar urea significantly increased (p < 0.05) the concentration of histamine in the wines compared with the control sample (65% in the treatment with 2 kg N ha(-1) and 93% in the treatment with 4 kg N ha(-1)), reaching higher concentrations than the threshold level where it could provoke toxic effects in the consumer (8-20 mg l(-1)). On the other hand, treatment with foliar urea did not increase the concentrations of other amines which could be toxic such as tyramine or phenylethylamine, nor amines such as putrescine which could enhance the toxic effect of histamine. In the case of the volatile amines containing secondary amine groups, the concentration of pirrolidine increased by 37% after treatment with 2 kg N ha(-1) and 61% after treatment with 4 kg N ha(-1).

Lateral engineering of surface states - towards surface-state nanoelectronics.

Patterned metal surfaces can host electron quantum waves that display interference phenomena over distances of a few nanometres, thus providing excellent information carriers for future atomic-scale devices. Here we demonstrate that collimation and waveguiding of surface electrons can be realized in silver-induced strain dislocation networks on Cu(111) surfaces, as a conceptual proof-of-principle of surface-state nanoelectronics (SSNE). The Ag/Cu(111) system exhibits featured surface bands with gaps at the Fermi energy, which are basic requirements for a potential SSNE material. We establish a solid analogy between the behavior of surface-state electrons and surface plasmons in patterned metal surfaces, thus facilitating the transfer of existing knowledge on plasmonic structures to the new scenario presented by engineered electronic surface-state nanostructures, with the advantage of a 1000-fold reduction in wavelength and geometrical parameters.

[Needs of the families in a Critical Care Unit]. / Necesidades de los familiares en una Unidad de Cuidados Críticos.

OBJECTIVES: To identify the needs of the family of admitted patients in the Critical Care Unit (CCU), and their level of satisfaction with the attention that they received. DESIGN: Cross-sectional, observational study. SETTING: Critical Care Unit, Virgen Macarena University Hospital, Seville. SUBJECTS OF THE STUDY: Two-hundred and sixty-eight families were selected through a random sampling system. INSTRUMENTS: A survey was developed using bibliography as reference. RESULTS: According to information, it was observed that receiving information after visiting hours and its access was difficult in regards to unforeseen changes in the patient's course. On the other hand, there were high levels of satisfactions with the attention received and with the nursing cares. Nevertheless, several deficiencies were observed in the identification of all the professionals, the visiting hours, the physical conditions of the waiting room, and privacy within patient's care environment. CONCLUSIONS: One of the principal needs of the relatives was to spend more time with the patients. Regarding to the information, access after visiting hours, and on that regarding unforeseen changes in the patient's evolution should be reviewed. Regarding satisfaction, in general, families were highly satisfied with the attention received, especially with the nurse's care. Nevertheless, these professionals should encourage the participation of the families in the patient's care. Moreover, all the areas of improvement observed should be dealt with urgently, mainly the visiting hours.

Electronic states in faceted Au(111) studied with curved crystal surfaces.

Vicinal Au(111) surfaces exhibit periodic faceting within a wide range of miscut angles. There, the system segregates two alternating phases with different step lattice constants d(w) and d(n). Using a curved crystal surface that allows a smooth variation of the surface orientation, we have studied, as a function of the miscut angle, the evolution of Au(111) faceted structures by scanning tunneling microscopy, and their electronic surface states by angle-resolved photoemission. We observe that surface bands reflect the two-phase character of the faceted system, i.e. we find d(w)- and d(n)-like states that evolve accordingly to the faceted structure. Using a photoemission calculation we prove that the apparently complex topology hides relatively simple physics, i.e. the same free-electron-like dispersion and repulsive step scattering that feature surface bands in stepped noble metal surfaces. On the grounds of such simulations, we discuss the possible interference of the electronic energy in the delicate free energy balance that determines the critical size of reconstructed (d(w)) and unreconstructed (d(n)) terraces during Au faceting.

Success rate and patient satisfaction with the Essure sterilisation in an outpatient setting: a prospective study of 857 women.

After 857 women with Essure system inserted for tubal obstruction as a method of sterilization in an outpatient setting, insertion is achieved in close to 99% of the women. Physician described the procedure as very difficult in 15% of the cases, mainly due to anatomical tubal anomalis or tubal spasm, and women felt highly satisfied in all cases.

Cribado del cáncer cervicouterino en colectivos de mujeres asintomáticas con factores de riesgo / Screening for cervical cancer in asymptomatic women with risk factors

Objetivos: Determinar las tasas de patología cervical y vaginal en colectivos de mujeres asintomáticas con factores de riesgo y su grado de adhesión al programa de cribado. Pacientes y métodos: Se asistió a 269 mujeres asintomáticas, reclutadas durante un período de un año (1998), que fueron interrogadas en relación con prácticas de riesgo y sometidas a citología, colposcopia y biopsia de cérvix, y determinación de anticuerpos frente al virus de la inmunodeficiencia humana. Se realizó un seguimiento durante 5 años. Resultados: La prevalencia de lesiones intraepiteliales del cérvix fue del 26,8 por ciento y la incidencia acumulada del 10,4 por ciento. El 62,5 por ciento no volvió a revisión en los 5 años de seguimiento, mientras que el 37,6por ciento volvió al menos una vez. Conclusiones: Las mujeres de los colectivos estudiados presentan altas tasas de patología cervicovaginal y alto riesgo de desarrollar cáncer de cérvix. La adhesión de estas mujeres al programa de cribado es muy baja. Debido a la poca precisión de la citología, estas mujeres deben someterse a una segunda técnica de cribado

Objectives: To determine the rates of cervical and vaginal disease in groups of asymptomatic women with risk factors and their degree of adhesion to the screening program. Patients and methods: 269 asimptomatic women attended during 1 year (1998) were interrogated in relation to risk practices; they underwent pap smear, colposcopy-biopsy of the cervix and determination of antibodies for VIH. A follow-up was made during 5 years. Results: The prevalence of intaepithelial lesions was 26.8 percents and the accumulated incidence was 10.4 percents; 62.5 percents of the women never returned to revision more, whereas 37.6 percents returned at least once. Conclusions: The women of the studied groups show high rates of cervical-vaginal pathology and high risk of developing cervical cancer. The adhesion of these women to the screening program is very low. Because of the low precision of the citology, this women must undergo a second screening test

Scattering of surface states at step edges in nanostripe arrays.

Surface states of noble metal surfaces split into Ag-like and Cu-like subbands in stepped Ag/Cu nanostripe arrays. The latter self-assemble by depositing Ag on vicinal Cu(111). Ag-like states scatter at nude step edges in Ag stripes, leading to umklapp bands, quantum size effects, and peak broadening. By contrast, Ag stripe boundaries become transparent to Cu-like states, which display band dispersion as in flat Cu(111). We find a linear relationship between the quantum size shift and peak broadening that applies in a variety of stepped systems, revealing the complex nature of step barrier potentials.

Fermi gap stabilization of an incommensurate two-dimensional superstructure.

The compressed, incommensurate approximately (9.5 x 9.5) moire superstructure of the Ag monolayer on Cu(111) displays a filled surface state band with a Fermi energy gap at the Brillouin zone boundary. By contrast, the surface band is gapless for the less compressed, commensurate (9 x 9) moire of two Ag layers. A simple estimate of the energy gain rendered by opening this gap gives a value similar to the elastic energy change required to modify the commensurate structure, thereby suggesting that the approximately (9.5 x 9.5) incommensurate phase is stabilized by such a gap opening. The possible presence of a charge density wave state is discussed.

Neuropharmacological profile of a selective sigma ligand, igmesine: a potential antidepressant.

Igmesine is a selective sigma (sigma(1)) ligand that was reported to exert antidepressant action through an unknown mechanism of action. A number of neurochemical measures were taken in this study in efforts to understand its mode of action. Following 21-day drug treatments, the actions of igmesine on a number of neurochemical measures were investigated. Data obtained showed significant decreases in the densities of beta-adrenergic but not 5-HT(1A), sigma(1) and GABA(B) receptors in fluoxetine (18%), desipramine (DMI, 32%) and igmesine (20%)-treated groups when compared with control. Tyrosine hydroxylase (TH) activity was significantly (30-32%) reduced in all treated groups. Further, fluoxetine and DMI excluding the igmesine-treated groups showed 85 and 40% reductions in serotonin (5-HT) and noradrenaline (NE) neuronal uptake, respectively. Following acute treatment, igmesine lacked activity for monoamine oxidase (MAO) A or B (IC(50)>10 microM). In in vivo studies, at behaviorally active doses, igmesine showed weak effects on the NE uptake but lacked activity in altering 5-HT and DA synthesis or antagonizing selective drug-induced depletion of monoamine neuronal uptake. N-methyl-D-aspartate (NMDA)-induced increases in cGMP was blocked by igmesine indicating that igmesine may interfere with the NMDA receptor/nitric oxide synthase/cGMP pathway. Although it appears that part of the pharmacological actions of igmesine is mediated by the monoaminergic system, there is still need to explore other possible mechanisms of antidepressant action.

Design and synthesis of novel quinoxaline-2,3-dione AMPA/GlyN receptor antagonists: amino acid derivatives.

PNQX (1,4,7,8,9,10-hexahydro-9-methyl-6-nitropyrido[3, 4-f]quinoxaline-2,3-dione) is a potent AMPA (IC50 = 0.063 microM) and GlyN (IC50 = 0.37 microM) receptor antagonist that was developed in our laboratories. While possessing a desirable in vitro and in vivo activity profile, this compound suffers from low aqueous solubility. In an effort to improve its potency and physical properties, we have designed and synthesized novel ring-opened analogues 4, 6, 9, and 11. Modeling analyses demonstrated that, while the 5-substituent in these analogues was forced to adopt an out-of-plane conformation due to steric contacts with neighboring substituents, the overall structure retained a good fit to a previously described AMPA pharmacophore model. This nonplanar orientation may lessen efficient packing in the solid state, compared to PNQX, leading to increased water solubility. Indeed, several nonplanar analogues containing appropriate functionalities, for example, the sarcosine analogue 9, were found to retain AMPA (IC50 = 0.14 microM) and GlyN (IC50 = 0.47 microM) receptor affinity and possess improved aqueous solubility compared to PNQX. The synthesis and the SAR of these compounds are discussed.
