Analysis of solitary pulmonary nodule after surgical resection in patients with 18F-FDG positron emission tomography integrated computed tomography in the preoperative work-up. / Análisis del nódulo pulmonar solitario tras su resección quirúrgica en pacientes con 18F-FDG PET-TC integrado en el estudio preoperatorio.

INTRODUCTION: To analyse clinicopathological characteristics of patients operated for pulmonary solitary nodule (PSN) and 18F-FDG integrated PET-CT scan after surgical resection. METHODOLOGY: Retrospective study on a prospective database of patients operated from January 2007 to October 2017 for PSN without preoperative diagnosis. Dependent variable was anatomopathological result (benign vs malignant) of PSN. Variables of the study were: age, sex, PET-CT uptake, SUVmax, smoking history, COPD, previous history of malignant disease, tumoral location, and tumour size on CT-scan. RESULTS: A total of 305 patients were included in this study, 225 (73.8%) men, 80 (26.2%) women, mean age = 63.9 (range 29-86 years), mean size PSN = 1.68 (s.d. .65 cm), benign = 46 (15.1%), malignant = 258 (84.6%), type of resection: pulmonary wedge = 151 (49.5%), lobectomy = 141 (46.2%), segmentectomy = 12 (3.9%), exploratory intervention = 1 (0.3%). Postoperative mortality was 1.9%. COPD = 50.8% cases, previous cancer disease = 172 cases (56.4%), smoking history = 250 cases (82.0%), positive PET = 280 cases (91.8%), PSN in upper pulmonary fields = 204 cases (66.9%), median SUVmax = 3.4 (range 0-20.7). Backward stepwise binary logistic regression model showed that age, SUVmax, previous malignant disease and female sex were independent risk factors with statistical significance (p < .05). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were 94.6%, 23.4%, 87.1%, 44.0%, and 83.6% respectively. There were 14 false negative cases (4.6%) and 36 false positive cases (11.8%). CONCLUSIONS: Age, SUVmax, previous malignant disease, and female sex were independent risk factors in our study. Each case should be individually evaluated in a multidisciplinary committee, and the patient's preferences or concerns should be kept in mind in decision-making. Surgical resection of PSN is not exempt from morbidity and mortality, even in sublobar or pulmonary wedge resection.

Cost of Hospitalizations due to Exacerbation in Patients with Non-Cystic Fibrosis Bronchiectasis.

BACKGROUND: Knowing the cost of hospitalizations for exacerbation in bronchiectasis patients is essential to perform cost-effectiveness studies of treatments that aim to reduce exacerbations in these patients. OBJECTIVES: To find out the mean cost of hospitalizations due to exacerbations in bronchiectasis patients, and to identify factors associated with higher costs. METHODS: Prospective, observational, multicenter study in adult bronchiectasis patients hospitalized due to exacerbation. All expenses from the patients' arrival at hospital to their discharge were calculated: diagnostic tests, treatments, transferals, home hospitalization, admission to convalescence centers, and hospitals' structural costs for each patient (each hospital's tariff for emergencies and 70% of the price of a bed for each day in a hospital ward). RESULTS: A total of 222 patients (52.7% men, mean age 71.8 years) admitted to 29 hospitals were included. Adding together all the expenses, the mean cost of the hospitalization was EUR 5,284.7, most of which correspond to the hospital ward (86.9%), and particularly to the hospitals' structural costs. The adjusted multivariate analysis showed that chronic bronchial infection by Pseudomonas aeruginosa, days spent in the hospital, and completing the treatment with home hospitalization were factors independently associated with a higher overall cost of the hospitalization. CONCLUSIONS: The mean cost of a hospitalization due to bronchiectasis exacerbation obtained from the individual data of each episode is higher than the cost per process calculated by the health authorities. The most determining factor of a higher cost is chronic bronchial infection due to P. aeruginosa, which leads to a longer hospital stay and the use of home hospitalization.

Diferencias entre los fumadores que no inician el tratamiento y los que sí lo inician / Differences between smokers who do not begin the treatment and those who do

Introducción: De los pacientes que acuden a la consulta a dejar de fumar, muchos no vuelven a la segunda consulta, por lo que no inician el tratamiento. Objetivo: Se intentaron determinar las características diferenciales de esta población respecto a los pacientes que sí iniciaron tratamiento. Pacientes y métodos: 1.484 pacientes acudieron a la Unidad de Tratamiento Especializado en Tabaquismo del Complejo Hospitalario Universitario de Albacete desde el 1 de enero de 2008 hasta el 31 de diciembre de 2012. Se utilizaron la Chi-cuadrado y la prueba exacta de Fisher para variables cualitativas y t de Student para cuantitativas y se realizó una regresión logística para evitar variables confusoras. El nivel de significación se estableció con una p < 0,05. Resultados: Se incluyeron en el estudio un total de 1.484 pacientes, de ellos, 731 sujetos abandonan el tratamiento sin acudir a la segunda consulta, esto es un 49,26% del total. En el modelo de regresión logística que se hizo no se observó que ninguna variable influyera de forma significativa. Conclusión: Hay muchos pacientes que, a pesar de acudir a una primera cita, no continúan con el tratamiento. Esto supone un fracaso que debemos estudiar

Introduction: Many of the patients who come to the consultation to stop smoking do not return to the second visit, so they do not initiate treatment. Objective: An attempt was made to determine the differential characteristics of the latter population regarding the patients who did initiate treatment. Patients and methods: 1484 patients came to the Smoking Habit Specialized Treatment Unit of the Complejo Hospitalario Universitario of Albacete from 1 January 2008 to 31 December 2012. The Chi-squared and the Fisher exact test were used for qualitative variables and the Student T test for quantitative variables and a logistic regression was performed to avoid confounding variables. Significance level was established with a p < 0.05. Results: A total of 1484 patients were included in the study. Of these, 731 abandoned treatment wihout coming to the second visit, this accounting for 49.26% of the total. It was not observed that any variable significantly affected the result in the logistic regressions model made. Conclusion: There are many patients who, in spite of coming to the first visit, do not continue with the treatment. This supposes a failure we need to study

Síndrome de apneas-hipopneas durante el sueño / Obstructive sleep apnoea síndrome

Introducción: El síndrome de apneas-hipopneas del sueño (SAHS) es altamente prevalente en la edad pediátrica y un problema importante de salud pública. Se pretende conocer la presentación clínica y polisomnográfica del SAHS infantil en nuestro medio.

Se recogen edad, sexo, datos antropométricos, clínicos, indicación y variables del estudio del sueño, tratamiento y evolución. Resultados: Doscientos treinta y cuatro niños. SAHS el 71,8%: moderado 42,3% y grave 44,6%. 60,7% varones y mediana de edad 5 años; el 78% en edad preescolar o escolar. Presentaban sobrepeso/obesidad 44%, ronquidos 93,4%, apneas 84,5% y somnolencia diurna 5,4%; 23 polisomnografías y 145 poligrafías: mediana de índice de apneas-hipopneas (IAH) 10, de SatO2 mínima 84% y de índice de desaturaciones 8, y media de sueño en supino 53,65% y de eventos en supino 57,61%. El tratamiento fue medidas higiénico-dietéticas en el 29,2%, CPAP el 6% y cirugía el 42,9%. Mejoraron los ronquidos y/o apneas el 69,4% y el peso el 32,4% de los niños con sobrepeso/obesidad. Conclusiones: La mayoría de los niños estudiados tenían un IAH patológico. Casi la mitad presentaban sobrepeso/obesidad y un alto porcentaje tenía SAHS moderado-grave. El tratamiento más indicado fue la cirugía. La evolución clínica fue favorable en casi el 70%. Menos de un tercio con SAHS y sobrepeso/obesidad mejoraron el peso

Introduction: Obstructive sleep apnoea (OSA) is highly prevalent in children and a major public health problem. An attempt is made to determine the clinical and polysomnographic presentation of paediatric OSA in our area. Patients and methods: Retrospective descriptive study of sleep tests conducted on children up to 14 years-old from 1999 to 2012 in the Sleep Unit of the University Hospital of Albacete. Age, gender, anthropometric, clinical data, indication and variables of sleep study, treatment, and outcomes were collected. Results: The study included 234 children. OSA was found in 71.8%, with 42.3% moderate and 44.6% severe. The majority were male (60.7%) and the mean age 5 was years, of whom 78% were pre-school or school age. There was overweight/obesity in 44%, with 93.4% snoring, apnoea 84.5%, and 5.4% daytime sleepiness. There were 23 polysomnographies and 145 polygraphies, with a median apnoea/hypopnoea index (AHI) of 10, Sat.O2 minimum 84%, desaturation index 8, and mean sleep supine 53.65% and supine events 57.61%. Treatment was lifestyle modifications 29.2%, CPAP 6%, and surgery 42.9%. Improved snoring and/or apnoea 69.4%, and weight 32.4% of overweight/obesity children. Conclusions: Most of the studied children had a pathological AHI. Almost half were overweight/obese, and a high percentage had moderate-severe OSA. Most frequent treatment was surgery. The clinical outcome was favourable in almost 70%. Less than a third with OSA and overweight/obesity improved weight
