Myxoid liposarcoma: MRI features with histological correlation.

BACKGROUND AND AIMS: Myxoid liposarcoma is classified in the group of sarcomas with adipose differentiation, which is the second most common group of sarcomas. However, myxoid liposarcoma is not a homogeneous entity, because the behavior and clinical course of these tumours can vary widely. This study aimed to describe the magnetic resonance imaging (MRI) features of myxoid liposarcomas and to determine whether the MRI features are associated with the histologic grade and can differentiate between low-grade and high-grade tumours and thus help in clinical decision making. MATERIAL AND METHODS: We studied 36 patients with myxoid liposarcomas treated at our centre between 2010 and 2018. We analysed clinical variables (age, sex, and tumour site) and MRI features (size, depth, borders, fatty component, myxoid component, non-fatty/non-myxoid component, apparent diffusion coefficient (ADC), and type of enhancement after the administration of intravenous contrast material). We correlated the MRI features with the histologic grade and the percentage of round cells. RESULTS: In our series, patients with myxoid liposarcomas were mainly young adults (median age, 43 years). There were no differences between sexes; 97.2% were located in the lower limbs, 86.1% were deep, and 77.8% had well-defined borders. Of the 23 myxoid liposarcomas that contained no fat, 16 (69.6%) were high grade (p = 0.01). All the tumors with a myxoid component of less than 25% were high grade (p = 0.01); 83.3% of those with a non-fatty/non-myxoid component greater than 50% were high grade (p = 0.03) and 61.5% had more than 5% round cells (p = 0.01). Diffusion sequences were obtained in 14 of the 36 patients; ADC values were high (median, 2 × 10-3 mm2/s), although there were no significant associations between low-grade and high-grade tumours. Contrast-enhanced images were available for 30 (83.3%) patients; 83.3% of the tumours with heterogeneous enhancement were high grade (p = 0.01). CONCLUSIONS: MRI can be useful for differentiating between high- and low-grade myxoid liposarcomas and can help in clinical decision making.

Recurrencia y mortalidad a largo plazo de los pacientes con síncope no cardiogénico / Long-term recurrences and mortality in patients with noncardiac syncope

Introducción y objetivos: La evolución a largo plazo de los pacientes que padecen síncope, una vez descartada su etiología cardiaca, no se ha descrito en profundidad. Se describe la evolución a largo plazo de esta población. Métodos: Durante 147 meses, se estudió a todos los pacientes remitidos a nuestra unidad de síncope tras haberse descartado una causa cardiaca. Resultados: Se incluyó a 589 pacientes consecutivos, 313 de ellos mujeres (53,1%), con una mediana de 52 [34-66] años. A 405 (68,8%) se les diagnosticó síncope vasovagal (SVV); a 65 (11%), síncope por hipotensión ortostática (SHO), y a 119 (20,2%), síncope de etiología desconocida (SED). Durante una mediana de 52 [28-89] meses de seguimiento, 220 (37,4%) tuvieron recurrencias (el 21,7%, 2 o más recurrencias) y se produjeron 39 muertes (6,6%). La recurrencia del síncope se produjo en el 41% de los pacientes con SVV, el 35,4% del grupo con SHO y el 25,2% del de SED (p=0,006). La recurrencia se correlacionó en el análisis multivariado con la edad (p=0,002), el sexo femenino (p<0,0001) y el número de episodios previos (< 5 frente a ≥ 5; p <0,0001). Fallecieron 15 pacientes (3,5%) con SVV, 11 (16,9%) con SHO y 13 (10,9%) con SED (p=0,001), El análisis multivariado asoció edad (p=0,0001), diabetes (p=0,007) y diagnóstico de SHO (p=0,026) y SED (p=0,020) con la muerte. Conclusiones: En los pacientes con síncope de origen no cardiaco, a los 52 meses de seguimiento, la tasa de recurrencias es del 37,4% y la de mortalidad, del 6,6%. Hay más recurrencias en los pacientes con perfil neuromediado y más mortalidad en los pacientes con perfil no neuromediado (AU)

Introduction and objectives: There are no in-depth studies of the long-term outcome of patients with syncope after exclusion of cardiac etiology. We therefore analyzed the long-term outcome of this population. Methods: For 147 months, we included all patients with syncope referred to our syncope unit after exclusion of a cardiac cause. Results: We included 589 consecutive patients. There were 313 (53.1%) women, and the median age was 52 [34-66] years. Of these, 405 (68.8%) were diagnosed with vasovagal syncope (VVS), 65 (11%) with orthostatic hypotension syncope (OHS), and 119 (20.2%) with syncope of unknown etiology (SUE). During a median follow-up of 52 [28-89] months, 220 (37.4%) had recurrences (21.7% ≥ 2 recurrences), and 39 died (6.6%). Syncope recurred in 41% of patients with VVS, 35.4% with OHS, and 25.2% with SUE (P=.006). In the Cox multivariate analysis, recurrence was correlated with age (P=.002), female sex (P <.0001), and the number of previous episodes (< 5 vs ≥ 5; P <.0001). Death occurred in 15 (3.5%) patients with VVS, 11 (16.9%) with OHS, and 13 (10.9%) with SUE (P=.001). In the multivariate analysis, death was associated with age (P=.0001), diabetes (P=.007), and diagnosis of OHS (P=.026) and SUE (P=.020). Conclusions: In patients with noncardiac syncope, the recurrence rate after 52 months of follow-up was 37.4% and mortality was 6.6% per year. Recurrence was higher in patients with a neuromedial profile and mortality was higher in patients with a nonneuromedial profile (AU)

Determination of a cutoff value for medication regimen complexity index to predict polypharmacy in HIV+ older patient.

OBJECTIVE: HIV+ patients have increased their life expectancy with a parallel increase in age-associated co-morbidities and pharmacotherapeutic complexity. The aim of this study was to determine an optimal cutoff value for Medication regimen complexity index (MRCI) to predict polypharmacy in HIV+ older patients. METHODS: A transversal observational single cohort study was conducted at a tertiary Hospital in Spain, between January 1st up to December 31st, 2014. Patients included were HIV patients over 50 years of age on active antiretroviral treatment. Prevalence of polypharmacy and it pattern were analyzed. The pharmacotherapy complexity value was calculated through the MRCI. Receiver operating characteristic curve analyses were used to calculate the area under the curve (AUC) for the MRCI value medications to determine the best cutoff value for identifying outcomes including polypharmacy. Sensitivity and specificity were also calculated. RESULTS: A total of 223 patients were included. A 56.1% of patients had polypharmacy, being extreme polypharmacy in 9.4% of cases. Regarding the pattern of polypharmacy, 78.0% had a cardio-metabolic pattern, 12.0% depressive-psychogeriatric, 8.0% mixed and 2.0% mechanical-thyroidal. The ROC curve demonstrated that a value of medication complexity index of 11.25 point was the best cutoff for predict polypharmacy (AUC=0.931; sensitivity= 77.6%; specificity=91.8%). CONCLUSIONS: A cut-off value of 11.25 for MRCI is proposed to determine if a patient reaches the criterion of polypharmacy. In conclusion, the concept of polypharmacy should include not only the number of prescribed drugs but also the complexity of them.

Influence of pharmacist intervention, based on CMO model, to improve activation in HIV patients.

OBJECTIVE: The aim of study was to evaluate the influence of pharmacist intervention based on "CMO model", to improve activation in HIV-patients. METHODS: Longitudinal, prospective, single-center study. Eligible patients were HIV-infected, taking antiretroviral treatment. The collected data included demographic characteristics, clinical and HIV-related and pharmacotherapeutic variables. The primary outcome was the variation of patient activation measured by Spanish adapted patient activation measure questionnaire. This questionnaire assesses people's knowledge, skills and confidence in managing their own health care. The assessment was performed at the beginning and 6 months after the program start, which consisted of individualized interventions planned in the stratification model, a motivational interview and a specific pharmacotherapeutic follow-up. RESULTS: A total of 140 patients were included. The most common regimens prescribed were based on non-nucleoside plus nucleoside reverse transcriptase inhibitor (44.0%) and more than half of the patients had chronic concomitant medication. The patients who achieved the highest activation level increased from 28.1% to 68.3% (p<0.0005). The relationship between this increase in patient activation and the stratification level that occurs in largest increases in patients with a low need level, where it was observed an improvement in the percentage of patients with high activation from 28.3% to 74.3% (p<0.001) after intervention. The percentage of patients with adequate adherence to concomitant treatment increased by 18.4% (p = 0.035). Baseline PAM values showed high activation for 28.6% (40 patients), intermediate for 43.6% (61) and low for 27.9% (39). CONCLUSIONS: CMO model has an important role for patient activation, improving adherence and health outcomes for HIV+ patients.

What have we learned from reporting safety incidents in the Surgical Block?: Cross-sectional descriptive study of two-years of activity of a multidisciplinary analytical group. / ¿Qué hemos aprendido de la notificación de incidentes de seguridad en el Bloque Quirúrgico?: estudio descriptivo transversal de 2 años de actividad de un grupo analizador multidisciplinar.

BACKGROUND AND OBJECTIVES: Incident Reporting Systems (IRS) are considered a tool that facilitates learning and safety culture. Using the experience gained with SENSAR, we evaluated the feasibility and the activity of a multidisciplinary group analyzing incidents in the surgical patient notified to a general community system, that of the Observatory for Patient Safety (OPS). MATERIAL AND METHOD: Cross-sectional observational study planned for two years. After training in the analysis, a multidisciplinary group was created in terms of specialties and professional categories, which would analyze the incidents in the surgical patient notified to the OPS. Incidents are classified and their circumstances analyzed. RESULTS: Between March 2015 and 2017, 95 incidents were reported (4 by non-professionals). Doctors reported more than nurses, at 54 (56.84%) vs. 37 (38.94%). The anaesthesia unit reported most at 46 (48.42%) (P=.025). The types of incidents mainly related to the care procedure (30.52%); to the preoperative period (42.10%); and to the place, the surgical area (48.42%). Significant differences were detected according to the origin of the notifier (P=.03). No harm, or minor morbidity, constituted 88% of the incidents. Errors were identified in 79%. The analysis of the incidents directed the measures to be taken. CONCLUSIONS: The activity undertaken by the multidisciplinary analytical group during the period of study facilitated knowledge of the system among the professionals and enabled the identification of areas for improvement in the Surgical Block at different levels.

[Evolution of the Complexity Index of the antiretroviral therapy in HIV+ patients in a real life clinical practice]. / Evolución del índice de complejidad de la terapia antirretroviral en paciente VIH en una cohorte de práctica clínica real.

OBJECTIVE: HIV infection has been one of the biggest successes in the healthcare world, mainly due to the appearance of antiretroviral treatment (ART). The complexity of this type of treatment has been one of the decisive factors in the follow-up of these patients. METHODS: An analytical, unicentric, retrospective observational study. We included all patients older than 18 years of age who were diagnosed with HIV who received ART in follow-up for the consultation of pharmaceutical pathology care during the year 2015. The evolution of the complexity index of ART over time and its relation with adherence to ART and concomitant treatment. RESULTS: A total of 619 patients were included in the study with a mean age of 47.03 ± 10.18 years. There was a reduction in CI over the years, with a significant decrease in the year 2013 and in 2015. The results obtained after the analysis of the secondary variables showed a significant relation between the adhesion to the ART and the CI of this. Patients have a lower CI (3.5) than non-adherent patients (4.25). (P = 0.003). CONCLUSIONS: The complexity of ART is being reduced mainly by new treatment strategies and the increasing appearance of pharmaceutical coformulations. A reduction in the complexity of ART assumes a better adherence to it.

Influence of adding etravirine on complexity index and patients' perceived complexity.

WHAT IS KNOWN AND OBJECTIVE: Adherence to highly active antiretroviral treatment (HAART) is an important predictive factor of treatment outcome. Medication regimen complexity can be one of the main causes of non-adherence. Thus, treatment simplification is a key strategy in the development of antiretroviral therapy. The aim of this study was to determine the influence of adding etravirine on complexity index and patients' perceived complexity of their treatment regimen. METHODS: We conducted a prospective two-centre observational study. Patients on etravirine-based therapy, for at least 6 months, who came personally to pharmacy departments for a drug refill from February to July 2012 were included. Data were collected for the current etravirine-based HAART and for the previous HAART without etravirine. The main variables were complexity index and patients' perceived complexity. We also evaluated the adherence during the 6 months before and after the introduction of etravirine into HAART. The complexity index was based on a score which takes into account the number of pills per day, the dosing schedule, the dosage form and any specific instructions linked to use of the drug. To evaluate the patients' perceived complexity of their current and previous HAART, patients were asked to assign a mark on a visual analogue scale ranging from 0 (minimum) to 10 (maximum). We assessed the differences in the variables collected between the current and previous antiretroviral therapy. Finally, we carried out a correlation analysis between the complexity index and the patients' perceived complexity. RESULTS AND DISCUSSION: Eighty patients were included. The complexity index was significantly reduced after the addition of etravirine to HAART (P = 0·035). Perceived complexity was also reduced (P = 0·015). After the introduction of the drug, the proportion of adherent patients increased from 65% to 81·3% (P = 0·002). The correlation between the complexity index and the patients' perceived complexity was positive (r = 0·594). The correlation increased (r = 0·696) when the difference between the complexity index before and after the introduction of etravirine in HAART grew. WHAT IS NEW AND CONCLUSION: The addition of etravirine to HAART results in a significant reduction in complexity index and patients' perceived complexity of their therapy. These changes were associated with better adherence to treatment.

Desarrollo y validación de un modelo predictivo para la identificación de pacientes infectados por el VIH con problemas relacionados con los medicamentos. Estudio predictor / Development and validation of a prediction model to identify HIV+ patients with drug-related problems. A prediction study

Objetivo: Desarrollar y validar un modelo predictivo para la detección de problemas relacionados con los medicamentos (PRM) en pacientes con tratamiento antirretroviral (TAR), durante su seguimiento periódico en consultas de atención farmacéutica (AF) y previamente a la dispensación. Método Para encontrar factores pronósticos de PRM, se realizó un modelo de regresión logística binaria tras un análisis univariante, el cual identificó variables independientes relacionadas con PRM que fueron introducidas en el modelo multivariante para la selección final. La validez del modelo se determinó por el método Shrinkage y la capacidad discriminatoria por el estadístico C-Harrell. Estudio multicéntrico, abierto, prospectivo. Se incluyeron pacientes infectados por el VIH con y sin PRM. Para el diseño del modelo se incluyeron variables demográficas, clínicas y farmacoterapéuticas (relacionadas o no con el TAR).Resultados Se incluyeron 733 pacientes. Las variables «adherencia», «prescripción de fármacos con necesidad de ajuste posológico» y «número de medicamentos totales prescritos (al margen del TAR)» se relacionaban de manera independiente con la aparición de PRM. Las probabilidades predichas por el modelo, personalizando los coeficientes por el método shrinkage uniforme mostraron un valor R2=0,962 para la muestra de construcción y R2=0,872 para la de validación. La capacidad discriminatoria del modelo fue de 0,816 para la muestra de construcción y 0,779 para la de validación. Conclusiones El modelo predictivo desarrollado y validado permite la detección de pacientes con tratamiento antirretroviral y con mayor riesgo de sufrir un PRM. Las variables predictoras utilizadas se corresponden con las manejadas habitualmente en la historia farmacoterapéutica del paciente, permitiendo su empleo sistemático en la práctica asistencial (AU)

Objective: To develop and validate a prediction model for the detection of drug-related problems (DRP) in patients on antiretroviral treatment during their regular monitoring in Pharmaceutical Care Clinics before dispensing drugs. Method: Open multicentre prospective study. HIV patients with and without DRP were included. Demographic, clinical and pharmacotherapy variables (related and unrelated to antiretroviral treatment) were included in the model design. To find prognostic factors for DRP, a binary logistic regression model was created after performing a univariate analysis that identified independent variables related to DRP these variables were introduced in the multivariate model for the final selection. Model validity was determined by the shrinkage method and the discriminatory power by Harrell’s C-index. Results: 733 patients were included. The variables ‘‘adherence’’, ‘‘prescription of drugs needing dosage adjustment’’, and ‘‘total number of drugs prescribed (apart from the antiretroviral treatment)’’ were independently related to the appearance of DRP. Probabilities predicted by the model, customising the coefficients using the uniform shrinkage method, showed aR2= 0.962 for the construction sample and a R2= 0.872 for the validation sample. The discriminatory capacity of the model was 0.816 for the construction sample and 0.779 for the validationsample. Conclusions: The developed and validated model enables detection of patients on antiretroviral treatment who are at a higher risk for experiencing a DRP. The prediction variables employed are commonly used in patient’s pharmacotherapy record, allowing the model to be used in routine clinical practice (AU)

Perspectiva multidisplicinaria del apoyo a la adherencia antirretroviral en Andalucía. Estudio Andhalusida / Multidisciplinary perspective on support for antiretroviral therapy adherence in andalusia. andhalusida study

Objetivo: Analizar la perspectiva de médicos, farmacéuticos y enfermeros sobre la importancia de diferentes actividades de apoyo a la adherencia antirretroviral e identificar las dificultades que se encuentran para poder incorporar las recomendaciones establecidas. Método Estudio observacional, transversal y con componente analítico. A partir de las recomendaciones 2008 de GESIDASEFH-PNS sobre mejora de la adherencia se diseñaron 3 cuestionarios: «Medidas ideales» (MI), «Medidas reales» (MR) y «Problemas de apoyo a la adherencia» (CPA). Se determinó el índice alfa de Cronbach para analizar la fiabilidad de los cuestionarios, así como coeficientes de concordancia entre las escalas MI y MR. Se aplicaron las pruebas de chi cuadrado o Montecarlo para analizar la relación entre proveedores de salud y los ítems de los 3 cuestionarios. Resultados Participaron 58 profesionales sanitarios. El porcentaje de respuesta obtenido fue del 76,3%. El índice alfa de Cronbach para los cuestionarios MI, MR y CPA fueron 0,852, 0,933 y 0,818, respectivamente. El coeficiente de correlación intraclase obtenido fue 0,280. Se obtuvieron diferencias significativas en las comparaciones múltiples de los cuestionarios MI y MR entre médicos y farmacéuticos. En el estudio de relaciones también se encontraron diferencias significativas en una de las respuestas al cuestionario MI, 3 al MR y 5 al CPA, principalmente debidas a la falta de tiempo y de formación. Conclusiones Se encontraron diferencias en la perspectiva que los diferentes proveedores de la salud tienen sobre las medidas de apoyo a la adherencia, siendo la falta de tiempo y de formación las principales causas que justifican esta desigualdad (AU)

Objective: To analyse physicians’, pharmacists’ and nurses’ perspectives on the importance of different antiretroviral treatment adherence support activities and identify the main obstacles to meeting established recommendations which health professionals encounter. Method: Cross-sectional observational and analytical study. Three questionnaires were designed based on 2008 GESIDA/SEFH/PNS recommendations for improving treatment adherence: ‘‘ideal measures’’ (IM), ‘‘real measures’’ (RM) and ‘‘adherence support problems’’ (ASP).Cronbach’s Alpha index was determined to analyse questionnaire reliability and correlation coefficients between the MI and MR scales. We applied the Chi-square test or Monte Carlo method to analyse the correlation between health providers and items on the three questionnaires. Results: Participants consisted of 58 health professionals. The response rate was 76%. The Cronbach Alpha indices for the IM, RM and ASP questionnaires were 0.852, 0.933 and 0.818respectively. The resulting intraclass correlation coefficient was 0.280. Significant differences were found for multiple comparisons of IM and RM questionnaires among physicians and pharmacists. The analysis of relationships between providers also found significant differences for one of the answers on the IM questionnaire, three on the RM and five on the ASP. Conclusions: We observed that several health professionals have different perspectives on measures of support for treatment adherence, with differences arising mainly due to lack of time and training

Objective: To evaluate the use of parenteral, enteral, and mixed nutrition in one acute and one chronic hospital. Design: Retrospective, non-randomised, observational study. Study sites: South Seville Health Area: Acute Hospital (H1) and Chronic Hospital (H2) with447 and 84 beds, respectively. We analysed all episodes of artificial nutrition administered in a 6-month period. Exclusion criteria included: age <18 years, oral supplements, and peripheral nutrition. Results: Artificial nutrition was used in a total of 568 episodes: 406 were enteral nutrition, 162were parenteral nutrition, constituting 4.95%, 3.54% and 1,41% of all hospitalisations, respectively. Enteral nutrition was more common at H2 hospital (n = 219, 15.5/100 hospitalisations)and parenteral nutrition was more commonly used at H1 (n = 155, 6.96/100 hospitalisations),with the ICU providing the majority of treatments (43.8%).Mixed nutritional support was used in 68 patients (0.59% of all cases), and was most commonlyused in the surgery department (n = 32, P<.001). The most commonly used enteral formula was the special diabetes diet; 41.2% at H1 and 46.6% at H2. Patient mortality with enteral nutrition was 37% at H1, 63% at H2, and was correlated with age (OR = 1.025, 95% CI: 1.006-1.046, P<.05), male sex (OR = 1.612, 95% CI: 1.023-2.540, P<.05), and time in ICU (OR = 49.379,95% CI: 11.971-203.675, P<.01).Conclusions: Enteral nutrition was more frequently used in both the acute and chronic hospitals.Parenteral nutrition and mixed nutritional support were used almost exclusively at the acutehospital (AU)

Enteral nutrition was more common at H2 hospital (n=219, 15.5/100 hospitalisations) and parenteral nutrition was more commonly used at H1 (n=155, 6.96/100 hospitalisations), with the ICU providing the majority of treatments (43.8%). Mixed nutritional support was used in 68 patients (0.59% of all cases), and was most commonly used in the surgery department (n=32, P<.001). The most commonly used enteral formula was the special diabetes diet; 41.2% at H1 and 46.6% at H2. Patient mortality with enteral nutrition was 37% at H1, 63% at H2, and was correlated with age (OR=1.025, 95% CI: 1.006-1.046, P<.05), male sex (OR=1.612, 95% CI: 1.023-2.540, P<.05), and time in ICU (OR=49.379, 95% CI: 11.971-203.675, P<.01). CONCLUSIONS: Enteral nutrition was more frequently used in both the acute and chronic hospitals. Parenteral nutrition and mixed nutritional support were used almost exclusively at the acute hospital.

Estudio de la relación entre la "imagen de sí" de niños y adolescentes que acudieron a tratamiento a una unidad de salud mental infanto-juvenil y la "imagen de sí" de sus padres / Study of the relationship between "self" of the children and adolescents who attende treatment at children and youth mental unit and "self" of their parents

El objetivo de esta investigación ha sido profundizar en el conocimiento de la relación entre la "imagen de sí" de los niños y adolescentes que acudieron a tratamiento a una Unidad de Salud Mental Infanto-Juvenil y la "imagen de sí" de sus padres, en los aspectos cognitivos, conductuales y emocionales. Estudio observacional que incluyó análisis descriptivo, tablas de contingencia y prueba de homogeneidad marginal, o prueba de McNemar. Se observó como hijos y padres presentan mejor imagen al respecto de sí, que al respecto de la imagen que creían dar a lo demás, además se sintieron poco valorados por padres, profesores y compañeros, y extraordinariamente bien valorados por sus abuelos. Ambos tenían una mala imagen en relación a cómo se comportan y los padres, se mostraron especialmente nerviosos al hablar de sí mismos. El ahondar en el conocimiento de esta relación permitió obtener una herramienta guía para la intervención psicoterapéutica(AU)

The research objective is made a careful study of knowledge the relationship between "self" of children and adolescents who attended treatment at Children and Youth Mental Health Unit, and "self" of their parents, in cognitive, behavioral and emotional issues. Observational study included descriptive analysis, contingency tables and marginal homogeneity test, or McNemar test. It could be observed that children and parents had better image about themselves, that the image they believed to give to the others. Furthermore, they felt under estimated by parents, teachers and peers, and extraordinary estimated by their grandparents. Both had a bad image about their behavior and father felt especially sad to talk about themselves. The focus on understanding of this relationship allowed obtaining a guiding tool for psychotherapeutic intervention(AU)

Estudio comparativo entre la ecografía y la neuroestimulación en el aprendizaje del bloqueo ciático poplíteo posterior / No disponible

Introducción: La anestesia regional guiada mediante ecografía es un campo en rápido crecimiento y su docencia está siendo objeto de estudio. Este trabajo compara la realización del bloqueociático-poplíteo posterior mediante ecografía (ECO) o neuroestimulación (NE) por médicos especialistas en formación. Material y método: Se realizó un estudio prospectivo aleatorizado, con los pacientes distribuidos en dos grupos: el grupo ECO mediante técnica guiada con ecografía; el grupo NE empleó referencias de anatomía de superficie más neuroestimulación, considerando válida una respuesta muscular entre 0.2-0.5 mA. Las variables registradas fueron: tiempo de ejecución, número de intentos, número de punciones vasculares y de parestesias, así como éxito del bloqueo. Las técnicas fueron realizadas por un único especialista en formación, sin experiencia previa en anestesia regional ni ecografía, bajo la supervisión de un anestesiólogo experto. Resultados: Se obtuvieron 19 casos (ECO: 10; NE: 9). El grupo ECO requirió menos tiempo que el NE (108,5-338,6 sg, IC95%; p < 0,005) y menor número de intentos, 1,6 ± 0,7 para ECO, frente 9,5 ± 3,8 para NE (media ± ds; p < 0,05), obteniendo éxito en primera punción en un 80% para ECO frente a al11,1% para NE (p < 0,05). El grupo ECO asoció una menor incidencia de punciones vasculares y de parestesias. La tasa de éxito de la técnica fue del 100% en el grupo ECO, frente al 67,7% en NE. Conclusiones: Estos resultados sugieren que el empleo de ecografía en el aprendizaje del bloqueo poplíteo posterior por especialistas en formación, pudiera facilitar la ejecución de la técnica, asociar menor morbilidad y proporcionar mayor éxito del bloqueo nervioso periférico (AU)

Background: The ultrasound-guided regional anesthesia is a rapidly growing field and its teaching is being studied. This paper compares the performance of the posterior popliteal sciatic blockadeby ultrasound (ECO) with that of neurostimulation (NS) carried out by specialist doctors in training. Material and method: A prospective randomized trial was conducted with patients divided into two groups: group ECO treated with ultrasound-guided technique, and group NE in which surface anatomy and neurostimulation references were used, considering valid a muscle response between 0.2 and 0.5 mA. The variables recorded were run time, number of attempts, number of vascular punctures and paresthesias, and success of the blockade. The techniques were performed by a single training specialist without prior experience in regional anesthesia and ultrasound, under the supervision of an expert anaesthesiologist. Results: 19 cases were obteined (ECO: 10, NE 9), the ECO required less time than NE (108,5-338,6 sg, 95%, p < 0.005)and fewer attempts, 1.6 ± 0.7 for ECO, versus 9.5 ± 3.8 for NE(mean ± sd, p < 0.05), and success was achieved on first puncture on 80% of attempts in ECO group, versus 11.1% in NE group (p< 0.05). The ECO group associated a lower incidence of vascular puncture and paresthesia. The success rate of the technique was 100% in the ECO group, versus 67,7% in NE group. Conclusions: These results suggest that the use of ultrasound in the posterior popliteal block learning by training specialists could facilitate the implementation of the technique, and provideless morbidity associated with more successful peripheral nerveblock (AU)

[A prevalence study of dysphagia and intervention with dietary counselling in nursing home from Seville]. / Estudio de prevalencia de disfagia e intervención con consejo dietético, en residencias de mayores de Sevilla.

INTRODUCTION: The prevalence of swallowing disorders widely varies depending on age and comorbidity. OBJECTIVES: To determine the prevalence of dysphagia and feeding disorders in elderly people living in nursing homes from the province of Seville and assess the effectiveness of dietary counselling. METHODS: We carried out a cross-sectional descriptive study on a population of 3921 residents distributed among 86 nursing homes. At the first phase of the study, we pretended to estimate the prevalence of dysphagia so that we selected 373 residents in 23 nursing homes. At the second phase, a sample of residents with dysphagia was selected, being reassessed a month later after receiving dietary counselling and basic measures for managing dysphagia. RESULTS: The median age was 80 (73.86) years, 60 (17.3%) had dysphagia and 50 (13.4%) had feeding difficulties. Both conditions were significantly (p < 0.05) associated with neurological diseases. Forty (11.3%) presented cerebrovascular accident and 123 (34.8%) dementia. Twelve patients with dysphagia were studied at the second phase, the mean age being 80.6+/-11.9 years, MNA 19 +/- 3, Barthel 24 +/- 27, and dysphagia Karnell level of 3-4 in 75% of the cases. These patients, receiving dietary counselling and basic measures for managing dysphagia, did not improve their intake level, dysphagia or dependency. CONCLUSIONS: The prevalence of dysphagia and feeding difficulties is high among nursing homes residents. The standard measures for controlling dysphagia are little effective in patients with severe dependence or advanced dementia.

Estudio de prevalencia de disfagia e intervención con consejo dietético, en residencias de mayores de Sevilla / A prevalence study of dysphagia and intervention with dietary councelling in nursing home from Seville

Introducción: La prevalencia de las alteraciones de la deglución varia ampliamente según la edad y comorbilidad. Objetivos: Determinar la prevalencia de disfagia y alteraciones de la alimentación en personas mayores que viven en residencias de la provincia de Sevilla, valorando la efectividad del consejo dietético. Métodos: Se realizó un estudio descriptivo transversal sobre una población de 3.921 residentes distribuidos en 86 residencias. En una primera fase del estudio se pretendía estimar la prevalencia de disfagia, para lo cual se seleccionaron 373 residentes en 23 residencias. En una segunda fase se seleccionó una muestra de residentes con disfagia, siendo reevaluados un mes después tras recibir consejo dietético y medidas básicas para control de disfagia. Resultados: La mediana de edad fue 80 (73-86) años, presentaron disfagia 60 (17,3%), y dificultades de alimentación 50 (13,4%). Ambas se asociaron de forma significativa (p < 0,05) con enfermedades neurológicas. Presentaron accidente cerebrovascular (AVC) 40 (11,3%), y demencia 123 (34,8%). En la segunda parte se estudiaron 12 pacientes con disfagia, de edad media 80,6 ± 11,9 años, MNA 19 ± 3, Barthel 24 ± 27, y grado de disfagia Karnell 3-4, en un 75% de los casos. Estos pacientes a los que se sometió a consejo dietético y medidas básicas para control de disfagia no mejoraron el nivel de ingesta, disfagia o dependencia. Conclusiones: La prevalencia de disfagia y dificultades de la alimentación es muy elevada en residencias. Las medidas estándar para el control de la disfagia son poco efectivas en pacientes con dependencia severa o demencia avanzada (AU)

[An analisys fo causes for the discontinuation of a simplified antiretroviral regimen with abacavir, lamivudine and zidovudine]. / Análisis de las causas de suspensión del régimen antirretroviral simplificado abacavir, lamivudina y zidovudina.

OBJECTIVE: To identify and analyze the most common causes for the discontinuation of antiretroviral therapy, including the co-formulation of abacavir, lamivudine and zidovudine (ABC-3TC-AZT). METHOD: An observational, retrospective study was carried out on patients receiving antiretroviral therapy with ABC-3TC-AZT seen in the Pharmacy Department s outpatient unit from February 2002 through June 2004. The causes for discontinuation among patients withdrawing from this therapy were analyzed. Adherence was assessed using computerized dispensation records. A Kaplan-Meier survival analysis was designed in order to identify factors predictive of discontinuation. RESULTS: In all, 114 patients (85 males, 74.6%) received this therapy - 25.4% of them were naïve patients - and 34.2% (39/114) withdrew from this regimen, amongst them 44.8% (13/29) of naïve subjects. In 92.3% of cases this happened before treatment week 48. Discontinuation causes included: adverse reactions (46.1%), voluntary discontinuation (33.3%), clinical decision (15.4%), and other reasons (5.1%). A possible hypersensitivity reaction to ABC was reported for 9 patients. A greater likelihood of discontinuation was associated with detectable viral load at therapy onset, ex-parenteral drug abuser status, and naïve status (p < 0.05). CONCLUSIONS: A high percentage of discontinuations due to adverse events and voluntary withdrawal was found, particularly early during treatment. Patients who may therapeutically benefit from this regimen, particularly naïve subjects, should be identified, and interventions to improve adherence and optimize recovery parameters should be implemented.
