Introduction and Objectives: Endoscopic ultrasound guided portal pressure gradient measurement (EUS-PPGm) would provide useful clinical information in patients with liver diseases. However, there is yet scarcely data on the clinical relevance of this EUS-guided procedure.We report our experience on EUS-PPGm focus on safety, clinical relevant findings, technical drawbacks and how to overcome them, aiming to make this procedure more safe, accurate and available. Materials and Patients: EUS-PPGm was performed with a therapeutic echoendoscope and a dedicated 25G needle in 30 consecutive patients. Assessment of NAFLD 25; idiopathic portal hypertension 3; evaluation for curative therapy in hepatocellular carcinoma (HCC) 2. EUS-guided bilobar liver biopsies (EUS-BLB) were also immediately performed in 26 patients (87%) with a 19G needle Results: EUS-PPGm was obtained in 25/30 patients (83%) being >5 mmHg in 10/22 NALFD patients (45%) without endoscopic and/or ultrasonographic signs of portal hypertension neither liver fibrosis on EUS-BLB. Mean time to obtain EUS-PPGm was 21±2 minutes.EUS-PPGm was not obtained in 5 cases. In 4 cases for excesive use of the elevator and up&down wheel and bending of the needle. In another case for exacerbating breathing movements. The hepatic and portal vein were difficult to punction in one and two cases, respectively having to transverse the vessels and reposition the needle.A self-limited bleeding from the cardias and a mild epigastric pain 2 day after a combined procedure were observed without other adverse events one month later. Conclusions: EUS-guided PPGm, even when combined with EUS-BLB, seems safe providing useful clinical information. Almost half of patients affected with NAFLD have portal hypertension diagnosed precociously in reversible stages providing a useful tool in precision Medicine, especially in the setting of obesity pandemic. There are technical aspects related to the needle and the position of the echoendoscope that should be known to improve the safety, accuracy and availibility of this procedure.

ABSTRACT Therapeutic options to treat bacterial infections caused by Gram-negative pathogens are limited due to the spread of multidrug resistance. Protein engineering of phage-derived lysins can play a key role in the search for new antimicrobial compounds targeting Gram-negative pathogens. A previous high-throughput screen of a combinatorial lysin library identified lysin 1D10 active against Acinetobacter baumannii under elevated human serum concentrations. The engineered lysin consists of four modules: cecropin A, a linker, cell wall-binding domain, and an enzymatic active domain. Using time-lapse microscopy, we show that 1D10 has a distinct antibacterial mode of action resulting in local cell wall bulging at the septum instead of cell-wide lysis, as observed for previously reported engineered lysins that target Gram-negative bacteria. Our results indicate that the activity of 1D10 relies on the antibacterial activity of both cecropin A (CecA) and the enzymatically active domain. Based on a truncation analysis, the role of each of the four modules of 1D10 was dissected. We further compared the antibacterial spectrum, thermostability, and cytotoxicity of cecropin A alone and lysin 1D10. Both lysin 1D10 and CecA are most active against A. baumannii and are not cytotoxic toward human keratinocytes. Lysin 1D10 unfolds at 57°C and has a remarkable refolding capacity, as it regains its activity even after exposure to 90°C and sterilization conditions, whereas CecA is inactivated at 70°C. Overall, the present study shows that an improved understanding of the killing mechanism and the protein properties will further support lysin engineering designs in the future. IMPORTANCE Engineered lysins are considered as highly promising alternatives for antibiotics. Our previous screening study using VersaTile technology identified 1D10 as a possible lead compound with activity against Acinetobacter baumannii strains under elevated human serum concentrations. In this manuscript, we reveal an unexpected mode of action and exceptional thermoresistance for lysin 1D10. Our findings shed new light on the development of engineered lysins, providing valuable insights for future research in this field.

Objectives: The course of progressive liver damage after achieving sustained virological response (SVR) with direct-acting antivirals (DAAs) remains undetermined. We aimed to determine risk factors associated with the development of liver-related events (LREs) after SVR, focusing on the utility of non-invasive markers. Methods: An observational, retrospective study that included patients with advanced chronic liver disease (ACLD) caused by hepatitis C virus (HCV), who achieved SVR with DAAs between 2014 and 2017. Patients were followed-up until December 2020. LREs were defined as the development of portal hypertension decompensation and the occurrence of hepatocellular carcinoma (HCC). Serological markers of fibrosis were calculated before treatment and one and two years after SVR. Results: The study included 321 patients, with a median follow-up of 48 months. LREs occurred in 13.7% of patients (10% portal hypertension decompensation and 3.7% HCC). Child–Pugh [HR 4.13 (CI 95% 1.74; 9.81)], baseline FIB-4 [HR 1.12 (CI 95% 1.03; 1.21)], FIB-4 one year post-SVR [HR 1.31 (CI 95% 1.15; 1.48)] and FIB-4 two years post-SVR [HR 1.42 (CI 95% 1.23; 1.64)] were associated with portal hypertension decompensation. Older age, genotype 3, diabetes mellitus and FIB-4 before and after SVR were associated with the development of HCC. FIB-4 cut-off values one and two years post-SVR to predict portal hypertension decompensation were 2.03 and 2.21, respectively, and to predict HCC were 2.42 and 2.70, respectively. Conclusions: HCV patients with ACLD remain at risk of developing liver complications after having achieved SVR. FIB-4 evaluation before and after SVR may help to predict this risk, selecting patients who will benefit from surveillance.

This prospective single-center study was designed to assess the clinical utility of the FilmArray® blood culture identification (BCID) panel for improving the diagnostic accuracy in neonatal sepsis. Results obtained using the FilmArray® BCID panel were correlated with results of blood culture in all consecutive neonates with suspicion of early-onset (EOS) and late-onset sepsis (LOS) attended in our service over a two-year period. A total of 102 blood cultures from 92 neonates were included, 69 (67.5%) in cases of EOS and 33 (32.3%) in LOS. The FilmArray® BCID panel was performed in negative culture bottles at a median of 10 h of blood culture incubation (IQR 8–20), without differences by the type of sepsis. The FilmArray® BCID panel showed a 66.7% sensitivity, 100% specificity, 100% positive predictive value, and 95.7% negative predictive value. There were four false-negative cases, three of which were Streptococcus epidermidis in neonates with LOS, and there was one case of Granulicatella adiacens in one neonate with EOS. We conclude that the use of the FilmArray® BCID panel in negative blood cultures from neonates with clinical suspicion of sepsis is useful in decision-making of starting or early withdrawal of empirical antimicrobials because of the high specificity and negative predictive values of this assay.

The prevalence of postnatal growth faltering (PGF) in preterm infants with very low birth weight (VLBW) (n = 112; and 2013–2017, n = 92) were compared. Results. In the second five-year period, a decrease in prevalence of PGF was observed (36.6% vs. 22.8%, p = 0.033), an increase in growth rate in the first 28 days (5.22 (4.35–6.09) g/kg/day vs. 11.38 (10.61–12.15) g/kg/day, p < 0.0001) and an increase in height standard deviation (SD) at 2 years (−1.12 (−1.35–−0.91) vs. −0.74 (−0.99–−0.49) p = 0.023). Probability of short stature at 2 years was directly related to daily weight gain in the first 28 days. Conclusions: when comparing two five-year periods in the last two decades, growth in VLBW preterm infants has improved, both during neonatal period and at two years of age.

Background and study aims: Endoscopy plays an essential role in managing patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. As such assessments are not always objective, different scores have been devised to standardize the findings. The main aim of this study was to assess the interobserver variability between the Mayo Endoscopy Score (MES), Ulcerative Colitis Endoscopy Index of Severity (UCEIS) and Ulcerative Colitis Colonoscopy Index of Severity (UCCIS) analyzing the severity of the endoscopic lesions in patients with ulcerative colitis. Patients and methods: This was a single-cohort observational study in which a colonoscopy was carried out on patients with UC, as normal clinical practice, and a video was recorded. The results from the video were classified according to the MES, UCEIS and UCCIS by three endoscopic specialists independently, and they were compared to each other. The Mayo Endoscopy Score (MES) was used to assess the clinical situation of the patient. The therapeutic impact was analyzed after colonoscopy was carried out. Results: Sixty-seven patients were included in the study. The average age was 51 (SD ± 16.7) and the average MES was 3.07 (SD ± 2.54). The weighted Kappa index between endoscopists A and B for the MES was 0.8; between A and C 0.52; and between B and C 0.49. The intraclass correlation coefficient for UCEIS was 0.92 among the three endoscopists (CI 95 %: 0.83–0.96) and 0.96 for UCCIS among the three endoscopists (CI 95 % 0.94–0.97). A change in treatment for 34.3 % of the patients was implemented on seeing the results of the colonoscopy. Conclusions: There was an adequate, but not perfect, correlation between the different endoscopists for MES, UCEIS, UCCIS. This was higher with the last two scores. Thus, there is still some subjectivity to be minimized through special training, on assessing the seriousness of the endoscopic lesions in patients with UC.

Background: Neonatal sepsis is a condition with high mortality and morbidity that contributes to high rates of antibiotic therapy at birth. In addition, very low birth weight newborns (VLBWN) are particularly vulnerable. Interleukin 6 (IL-6) seems to be an early and effective marker that could help a better selection of patients to be treated. This study aimed to evaluate the use of antibiotics in the first 72 hours of life in VLBW infants before and after using IL-6 as an infection marker. Also, we wanted to analyze the differences in morbidity and mortality during admission and other factors associated with the decision to start antibiotic treatment. Methods: We conducted a cohort retrospective study. We included VLBWN born in our hospital or admitted before 72 hours of life in two two-year periods (2007-2008 and 2011-2012). Results: Antibiotics use during the first 72 hours of life was analyzed as the primary variable, which was reduced by 20% on the second period (p = 0.002). Regarding the analysis of secondary variables, we found no significant differences in mortality during hospital admission and the incidence of nosocomial sepsis, enterocolitis, or invasive fungal infection. The multivariate analysis indicated extreme prematurity and the study group as the most strongly related factors to the start of antibiotic therapy. Conclusions: IL-6 was a useful marker of infection to reduce the use of antibiotic therapy in VLBW infants without increasing mortality.

ABSTRACT Background and aims: infliximab has changed the natural history of inflammatory bowel disease (IBD). The advent of biosimilar treatments such as CT-P13 will hopefully improve the availability of biological therapies. Data with regard to drug switching are currently limited. The objective of the study was to assess the effectiveness and safety of switching from the reference product (RP), infliximab, to CT-P13 in patients with IBD. Methods: this was a multicenter prospective observational study in patients with Crohn's disease (CD) and ulcerative colitis (UC). All patients had switched from infliximab RP (Remicade(r)) to CT-P13 treatment and were followed up for 12 months. The efficacy endpoint was the change in clinical remission assessed at 0 and 12 months, according to the Harvey-Bradshaw score and partial Mayo score for patients with CD and UC, respectively. Adverse events were monitored and recorded throughout the study. Results: a total of 167 patients (116 CD/51 UC) were included; 88.8% (103/116) of patients with CD were in remission at the time of the drug switch and 69.7% were in remission at 12 months. The Harvey-Bradshaw (HB) score significantly changed at 12 months (p = 0.001); 84.3% (43/51) of patients with UC were in remission at the time of the drug switch and 76.7% were in remission at 12 months. No significant changes in the median partial Mayo score (p = 0.87) were observed at 12 months. Serious adverse events related to medication were reported in 12/167 (7.2%) cases. Conclusion: switching from infliximab RP to CT-P13 is safe and effective at 12 months. The loss of efficacy at 12 months was 15.7%.

We document novel facts about the relationship between aggregate growth and firm dynamics using a large set of countries. We argue that firm employment patterns are not necessarily informative about cross-country differences in aggregate growth because they are induced by changes in the productivity of a firm relative to others. In contrast, aggregate growth is linked to average firm-level productivity growth and firm age. We formalize this intuition through a tractable model of endogenous aggregate growth and firm dynamics where firms realize positive returns to investment with some probability. We find that cross-country disparities in this probability can account for two-thirds of the variation in aggregate growth. (JEL D21, D22, E23, O4), I. INTRODUCTION An extensive literature relates differences in the level of development across countries to differences in firm employment and productivity distributions (among them, Hsieh and Klenow 2009; Bartelsman, Haltiwanger, [...]

Background: Several studies have reported positive efficacy outcomes for patients with inflammatory bowel disease treated with CT-P13, an infliximab biosimilar. Data from follow-up periods longer than 1 year are still scarce. Here, we assessed the long-term efficacy data, loss of response and safety after switching from infliximab to CT-P13 in patients with inflammatory bowel disease. Methods: This was a prospective single-center observational study involving patients with moderate-to-severe Crohn’s disease and ulcerative colitis switched from infliximab to CT-P13 treatment and reviewed up to 24 months. Efficacy and loss of response were measured using the Harvey–Bradshaw (HB) index and partial Mayo score for patients with Crohn’s disease and ulcerative colitis respectively. C-reactive protein, infliximab drug levels, adverse events and antidrug antibodies were also monitored throughout the study. Results: A total of 64 patients with Crohn’s disease and 36 patients with ulcerative colitis were included. Most of them (72%) remained on CT-P13. Overall, 28% of patients discontinued the therapy due to loss of response, adverse events or long-lasting clinical remission. Remission at 18 and 24 months occurred in 69.9% and 68.5% of patients, respectively. Dose increase was performed in 22% of patients, with remission being reached in 60% of them. HB index, partial Mayo score, C-reactive protein and infliximab drug levels did not show significant changes. Serious adverse events were reported in 14% of patients. Overall, two patients developed low levels of antidrug antibodies. Conclusions: Most of the patients switching from original infliximab were maintained on CT-P13 at 2 years of follow up with a good profile of efficacy and safety.

Introduction: Capsule endoscopy (CE) has become a first-line tool for small bowel (SB) examination. However, adverse events (AEs), such as CE retention or aspiration, may occur. The aims of this study were to evaluate incidence, clinical outcomes and therapeutic approaches of CE-related AEs in the largest series published to date. Methods: Data from 5428 procedures performed at 12 institutions between August 2001 and January 2012 were retrospectively analyzed. Baseline patient characteristics; procedure; type, localization and symptoms before/after AEs; previous patency tests performed; therapeutic management and patient's outcome were recorded. Results: The overall incidence of CE-related AEs was 1.9%: 2.0% for SB, 0.9% for esophageal and 0.5% for colon CE. The incidence of capsule retention was significantly higher than capsule aspiration (1.87% vs. 0.003%; p < 0.05), in patients suffering from inflammatory bowel disease (IBD) than in obscure GI bleeding (OGIB) (3.3% vs. 1.5%; p < 0.05) and in patients with the combination of nausea/vomiting, abdominal pain and distension. The SB was the most frequent localization of retention (88.2%). The use of patency tests -except for Patency© capsule- before CE was not a good predictor for AEs. Most of the patients with AEs developed no or mild symptoms (97%) and were managed by non-surgical methods (64.4%). Conclusions: CE-related AEs are uncommon and difficult to predict by imagiological examinations. SB retention, that is usually asymptomatic, is the most frequent AE. In absence of symptoms, non-surgical management of CE-related AEs is recommended.

Endoscopic ultrasound (EUS)-guided drainage is now the treatment of choice in cases of pancreatic pseudocysts and walled-off necrosis, especially in the absence of luminal bulging and in patients with portal hypertension. Malignant refractory ascites usually heralds a poor prognosis and substantially impairs the quality of life of patients because of the symptoms experienced and the need for repeated paracentesis. EUS-guided placement of lumen-apposing, fully covered, self-expandable metal stents (FCSEMS) has been reported for the drainage of malignant ascites. Herein, we present the results of EUS-guided placement of plastic pigtails stents for the drainage of refractory malignant ascites in three patients. The aim was to improve symptoms and minimize the possible drawbacks of large-caliber FCSEMS. In this preliminary experience, EUS-guided placement of plastic stents was feasible and avoided further paracentesis.

Introduction: PillCam© colon capsule endoscopy (CCE) enables the study of colonic diseases in a safe and non-invasive way, although there are aspects that need to be improved. Current methods of bowel preparation lead to discordant rates of adequate cleansing and CCE excretion. Aims: To compare the efficacy of colon cleansing using two different regimes (2L PEG plus ascorbic acid versus 4L PEG alone) for PillCam Colon (C2) capsule endoscopy. Methods: Fifty eight patients included in this prospective study and randomized to: Group A, PEG plus ascorbic acid regimen (n = 28, 12 F/16 M) or group B, PEG alone regimen (n = 30, 14 F/16 M). The degree of cleansing was categorized into "excellent-good" or "fair-poor", according to Leighton's recently published preparation scale. CCE excretion rate and colon cleansing were assessed. Patients underwent to PillCam colon of second generation (C2). Results: Cleansing was considered to be excellent-good in 78 % of cases in group A and in 64 % of cases in group B, with no significant difference between the groups (p = 0.252). Nevertheless, when the grade of cleansing was analyzed in segments, a significant difference was found in the cecum and transverse colon. No differences were observed in the bubble effect between preparations. The excretion rate was 93 % in group A versus 70 % in group B (p = 0.043). Conclusions: These results suggest that a 2L PEG plus ascorbic acid regimen is at least as effective as a 4L PEG regimen. This regimen may be considered an effective alternative which would improve compliance because a smaller volume is required.

Background and study aims: Colon capsules display images from the moment they are ingested, making the study of other extracolonic areas possible. The aim of this study was to analyze the significance of these extracolonic findings. Patients and methods: In this single-center, prospective study, 165 patients underwent colon capsule endoscopy (CCE) between September 2009 and October 2012 to rule out colonic pathology. Images were recorded, without interruptions, from the moment the capsule was ingested until its battery ran out. The study was deemed complete when the capsule had traveled from the esophagus to excretion or until the hemorrhoidal plexus was observed. Results: CCE was used for colorectal cancer (CRC) screening (81.2 %), to investigate for chronic diarrhea (9.7 %) and chronic iron deficiency anemia (6.1 %), and for patients with incomplete colonoscopy (3.0 %). The capsule returned findings in the esophagus in 52.1 % of patients, in the stomach in 45.5 % of patients, and in the small bowel in 70.7 % of patients, with the findings being considered relevant in 4.9 %, 9.7 %, and 22.6 % of patients, respectively. The whole extent of the digestive tract was fully recorded in 86.1 % of patients and the Z line could be fully observed in 57.6 % of patients. There were no adverse events. Conclusions: CCE allows the recording of images from almost the whole extent of the digestive tract in most patients, enabling relevant pathologies to be identified in extracolonic areas, particularly the small bowel. Technical and procedural improvements are still necessary in order to achieve better observation of the stomach and esophagus.

Background: adalimumab, a human anti-TNF, is an effective induction and maintenance therapy for patients with moderate to severe Crohn's disease. It seems to be effective in patients with resistance to infliximab, too, though the experience is more limited. Aim: to evaluate the efficacy of adalimumab, in patients with Crohn's disease (CD) and failure to previous treatment with infliximab. B twenty-five patients with CD and failure to previous treatment with infliximab were enrolled; they were treated with 160/80 (24 patients) and 80/40 (1 patient) induction doses. We analyze clinical response to treatment with adalimumab by the Crohn's disease Activity Index (CDAI) and plasma concentration of C-reactive protein (CRP), steroid sparing and complete fistula closure at week 48. Results: eighteen out of twenty-five patients (72%) achieved clinical remission (CDAI score < 150) at week 24 and 15/25 (60%) patients at week 48. There was a statistically significant difference (p < 0.01) in CRP serum levels from 21 to 8 mg/dl at week 48. Nine out of fifteen patients (60%) treated with corticosteroids were able to discontinue steroids. Three out of eleven patients (27%) with fistulizing Crohn's disease had complete fistula closure after the treatment. Seventy two percent of the patients (18/25) needed to increase adalimumab to weekly dose, in order to maintain clinical response. Five out of twenty-five patients (20%) had adverse events; two of them (8%) with serious adverse events (tuberculous meningitis and abdominal abscess) that forced the withdrawal of treatment. Conclusions: according to these data, adalimumab provides a clinical and analytical improvement in patients with CD and failure to previous therapy with infliximab.Introducción: adalimumab, un anti-TNF humano, ha demostrado ser efectivo en la inducción y tratamiento de mantenimiento de la enfermedad de Crohn moderada-grave. Existe menos experiencia, pero este fármaco parece también eficaz en los pacientes con pérdida de respuesta o intolerancia al infliximab. Objetivo: evaluar la eficacia de adalimumab durante un año, en nuestra serie de pacientes con enfermedad de Crohn (EC) y fracaso en el tratamiento previo con infliximab. Métodos: se incluyen 25 pacientes con enfermedad de Crohn y fracaso previo a la terapia con infliximab, que son tratados con adalimumab. Se utilizaron dosis de inducción de 160/80 mg en 24 pacientes y dosis de 80/40 en un paciente. Analizamos la respuesta clínica al tratamiento con adalimumab mediante el Índice de actividad de la enfermedad de Crohn (CDAI) y las concentraciones plasmáticas de proteína C reactiva (PCR), el cese de la corticoterapia y el cierre completo de las fistulas en la semana 48. Resultados: dieciocho de veinticinco pacientes (72%) alcanzan la remisión clínica (CDAI < 150) en la semana 24 y 15/25 pacientes (60%) en la semana 48. Esto se acompañó de un descenso de los niveles de PCR de 21 a 8 mg/l en la semana 48. En nueve de quince pacientes (60%) que tomaban corticoides, se consiguió su retirada. Tres de once pacientes (27%) con enfermedad fistulosa presentaron un cierre completo de las fístulas tras el tratamiento con adalimumab. Un 72% de los pacientes (18/25) necesitaron, a lo largo del seguimiento, acortar el intervalo de tratamiento a una semana para mantener la respuesta. Cinco de veinticinco pacientes (20%) presentan efectos secundarios y en 2 de ellos (8%) fue precisa la retirada del fármaco (meningitis tuberculosa y absceso abdominal). Conclusiones: el tratamiento con adalimumab proporciona una mejoría clínica y analítica en un número significativo de pacientes con EC y fracaso previo a la terapia con infliximab.

Introduction: several studies have pointed out the effectiveness of the PillCam© colon capsule endoscopy (CCE) compared with the colonoscopy in the study of the colonic pathology. Aims and methods: the objective of our study was to assess the agreement in the diagnosis of CCE with conventional colonoscopy as well as its sensitivity and specificity, and to describe the findings of the CCE in our clinical practice. Consecutive patients with abdominal symptoms were included in the study. The CCE was performed as previously reported (with PEG and sodium phosphate as laxative agents). The nature and location of the findings, colonic transit time, complications, cleanliness degree and consistency with diagnostic colonoscopy, when performed, were analyzed. Results: a total of 144 subjects (67 women and 77 men); (52.17±16.71 years) with the following indications were included: screening of Colorectal cancer (88 patients), control after polipectomy (24), incomplete colonoscopy (7), rectal bleeding (10), anemia (8), diarrhea (7). The CCE exploration was complete in 134/144 cases (93%), with no case of retention. The preparation was good-very good in 88/134 (65,6%), fair in 26/134 (19,4%) and poor in 20/134 (15%) of the cases. The average colonic transit was of 140.76 min (9-603). Any adverse effect was notified. In 44 cases a colonoscopy was carried out after CCE (results were hidden from another endoscopist). Compared to colonoscopy, the rate of agreement was 75,6%, the sensitivity was 84% and the specificity 62,5%, PPV was 77,7% and NPV was 71,4 %. The colonic findings in 134 CCE were: in 34 cases CCE it did not show lesions, diverticulosis in 63 explorations, polyps in 43, angiodysplasias in 15, Crohn's Disease in 9 and ulcerative colitis in other 8 cases. Conclusions: the CCE is an effective and reliable technique for the detection of lesions in colon, and because of its high agree-ment with the colonoscopy, it could be useful in clinical practice. Further studies with large seria and cost-effectiveness analysis are needed to confirm these data.

Introducción. El objetivo de la presente investigación ha sido comparar mediante un ensayo clínico la efectividad de una Psicoterapia Breve con el tratamiento habitual de los Trastornos Mentales Comunes en los Centros de Salud Mental (CSM) de Asturias. La introducción general a este estudio se ha descrito por Fernández-Méndez y cols. (2010) y se remite a los lectores a ese artículo para más detalles respecto al fundamento, diseño, tratamientos y procedimientos de la investigación. Sujetos y método. Se seleccionaron al azar 216 personas mayores de 14 años que consultaban por primera vez en seis CSM y que fueron diagnosticadas de trastornos depresivos, de ansiedad y/o de adaptación. Ciento cuarenta y una cumplían los criterios de inclusión y aceptaron participar en la investigación, siendo asignadas al azar a dos grupos: Psicoterapia breve integradora-ecléctica (n = 76) o Tratamiento habitual en los CSM (n = 65). Se han comparado sus resultados a los 6, 12, 24 y 36 meses en diversos índices de mejoría clínica, funcionamiento psicosocial e indicadores sanitarios indirectos. Los datos se han obtenido del Registro de Casos Psiquiátricos, de la Historia Clínica y del propio paciente. Se han usado los siguientes instrumentos: Impresión Clínica Global (ICG, Guy, 1976), Inventario de Discapacidad de Sheehan (SDI, Sheehan, 1996) y Cuestionario de Satisfacción (Moré y Muñoz, 2000). Resultados. El programa de Psicoterapia breve ha sido más efectivo que el tratamiento habitual: Obtiene una mayor tasa de altas y los sujetos muestranmayor satisfacción. Estas diferencias se dan tanto a los seis meses como al año y a los dos años de iniciarse los tratamientos. Además, aunque el número medio de sesiones es igual en ambos grupos (en torno a seis), el tratamiento experimental duró mucho menos tiempo. Conclusiones: La Psicoterapia ha resultado ser un tratamiento viable y efectivo para la mayoría de los casos que consultan en los CSM.
