Foreign body impaction is a frequent indication of urgent endoscopy. One of the reasons for impaction is eosinophilic oesophagitis (EE). To analyze characteristics of oesophageal foreign body impactions and their relationship with eosinophilic oesophagitis.In this retrospective study, urgent endoscopies in a tertiary care centre were analyzed. We included all urgent endoscopies due to bolus and foreign body impactions performed between September 1st 2018 and September 1st 2020. We reviewed clinical data of all patients who were diagnosed with EE and compared it to impactions that were due to other motives. The mean follow-up time was 18.7 months.693 urgent endoscopy procedures were performed. 239 (34%) of these were due to foreign body ingestion. Mean age of the patients was 63 years old and 135 (63%) were men. EE was diagnosed in 36 (17%) patients. The factors associated with EE were age, to be younger than 50 years (OR, 7.3; 95% CI, 1.1-48.4; p=0.04), asthma/rhinitis/atopic dermatitis (OR, 8.9; 95% CI, 2.3-35.3; p=0.002), findings in the endoscopy as trachealization (OR, 9.7; 95% CI, 1.3-70.9; p=0.03) and psychotropic/calcium channel blocker drugs (OR, 0.09; 95% CI, 0.009-0.9; p=0.04). 15 (7%) patients died. In 6 of them death was impaction-related. None patients with EE died.Foreign body impaction in the upper gastrointestinal tract due to EE is a frequent cause of urgent endoscopy. Being under 50 years of age, having asthma/rhinitis/atopic dermatitis, trachealization on the oesophagus and not taking psychotropic/calcium channel blocker drugs are factors associated with the diagnosis of EE. Mortality in the follow-up of patients without EE is important.

Some quality indicators of proper health care in patients with colorectal cancer have been established.Our goal was to evaluate the relationship between performing of certain procedures or treatments, included as quality indicators, and some outcomes of indicators in the follow-up of colorectal cancer patients.This was a prospective cohort study of patients diagnosed with colorectal cancer that underwent surgery and were followed at 1, 2, 3, and 5 years. CT scanning, colonoscopy, chemotherapy, and radiotherapy were evaluated in relation to various clinical outcomes and PROM changes over 5 years. Multivariable generalized linear mixed models were used to evaluate their effect on mortality, complications, recurrence, and PROM changes (HAD, EQ-5D, EORTC-Q30) at the next follow-up.CT scanning or colonoscopy was related to a decrease in the risk of dying, while chemotherapy at a specified moment was related to an increased risk. In the case of recurrence, CT scanning and chemotherapy showed statistically increased the risk, while all the procedures and treatments influenced complications. Regarding PROM scales, CT scanning, colonoscopy, and radiotherapy showed statistically significant results with respect to an increase in anxiety and decrease in quality of life measured by the EORTC. However, undergoing radiotherapy at a specified moment increased depression levels, and overall, receiving radiotherapy decreased the quality of life of the patients, as measured by the EuroQol-5d.After adjustment for sociodemographic factors, comorbidities, and severity of the disease, performing certain quality indicators of proper health care in patients with colorectal cancer was related to less mortality but higher adverse outcomes.ClinicalTrials.gov Identifier: NCT02488161.

The prevalence of depressive symptoms immediately after the diagnosis of colorectal cancer (CRC) is high and has important implications both psychologically and on the course of the disease. The aim of this study is to analyse the association between depressive symptoms and CRC survival at 5 years after diagnosis.This multicentre, prospective, observational cohort study was conducted on a sample of 2602 patients with CRC who completed the Hospital Anxiety and Depression Scale (HADS-D) at 5 years of follow-up. Survival was analysed using the Kaplan-Meier method and Cox regression models.According to our analysis, the prevalence of depressive symptoms after a CRC diagnosis was 23.8%. The Cox regression analysis identified depression as an independent risk factor for survival (HR = 1.47; 95% CI: 1.21-1.8), a finding which persisted after adjusting for sex (female: HR = 0.63; 95% CI: 0.51-0.76), age (70 years: HR = 3.78; 95% CI: 1.94-7.36), need for help (yes: HR = 1.43; 95% CI: 1.17-1.74), provision of social assistance (yes: HR = 1.46; 95% CI: 1.16-1.82), tumour size (T3-T4: HR = 1.56; 95% CI: 1.22-1.99), nodule staging (N1-N2: HR = 2.46; 95% CI: 2.04-2.96), and diagnosis during a screening test (yes: HR = 0.71; 95% CI: 0.55-0.91).There is a high prevalence of depressive symptoms in patients diagnosed with CRC. These symptoms were negatively associated with the survival rate independently of other clinical variables. Therefore, patients diagnosed with CRC should be screened for depressive symptoms to ensure appropriate treatment can be provided.

AimTo evaluate the influence of an algorithm designed to incorporate reflex testing according to haemogram results for analytical tests ordered to investigate anaemia.MethodsIn 2020, a new request for ‘initial study of anaemia’ was created in three primary care pilot centres for suspected anaemia or new anaemias. A haemogram was ordered and the remainder of the tests were created in a reflex manner according to an algorithm integrated in the laboratory information system that also generates a comment that is completed and validated by a haematologist. The demand for tests was evaluated over three time periods.ResultsOf 396 requests, anaemia was detected in 80 (20.2%), with 26 microcytic anaemias (6.57%), 20 iron deficiency anaemias, 41 (10.3%) normocytic anaemias and 13 macrocytic anaemias (3.28%); 4 with folate deficiency; and 1 haemolytic anaemia. No haematological diseases were detected. Twenty-four (6.06%) cases exhibited microcytosis/hypochromia without anaemia, 12 of which exhibited iron deficiency. Four young women exhibiting within-limit haemoglobin levels had iron deficiency. There were 56 (14.1%) cases of macrocytosis without anaemia.With the new profile of ‘initial study of anaemia’, the demand for tests was reduced and was significantly lower than in the remainder of primary centres for iron, transferrin, ferritin, vitamin B12 and folate.ConclusionsA new profile of ‘initial study of anaemia’ in the request form with algorithms integrated in the laboratory information system enabled submission of orders and decreased the demand for unnecessary iron, transferrin, ferritin, vitamin B12 and folate tests.

Objective There is limited information on health service use or patient-reported outcomes when comparing the effectiveness of laparoscopic with that of open surgery. The aim was to compare the effectiveness of laparoscopic with that of open surgery up to 2 years after intervention in patients with colon cancer. Methods Prospective cohort study of patients with colon cancer who underwent surgery (laparoscopic or open surgery) between June 2010 and December 2012, at 22 hospitals. Main outcomes of the study were mortality, complications, reoperation, readmission, and patient-reported outcome measures (PROMs), as measured using the Hospital Anxiety and Depression Scale, Duke-UNC, EuroQol-5D, and European Organisation for Research and Treatment of Cancer-Q30 and Q29 at baseline, and 30 days and 1 and 2 years after surgery. Multivariable multilevel logistic regression and generalized linear models were used in analyses after adjusting for specific propensity scores developed for each outcome and time point. Results In the multivariable analysis, the complication rates up to 30 days (infectious, surgical, and medical) and 1 year (surgical), and readmission rate at 30 days and at 2 years were higher among patients who underwent open surgery than among those who underwent laparoscopic surgery. There were no differences between the two surgical approaches in all other parameters assessed and in changes of all PROMs. Conclusions Though in most outcomes both surgical approaches provide similar results up to 2 years after intervention, still the rates of some complications and readmission, mainly up to 30 days, are higher in open surgery.

Background The aim of this study was to identify predictors of mortality in elderly patients undergoing colorectal cancer surgery and to develop a risk score. Methods This was an observational prospective cohort study. Individuals over 80 years diagnosed with colorectal cancer and treated surgically were recruited in 18 hospitals in the Spanish National Health Service, between June 2010 and December 2012, and were followed up 1, 2, 3, and 5 years after surgery. Sociodemographic and clinical data were collected. The primary outcomes were mortality at 2 and between 2 and 5 years after the index admission. Results The predictors of mortality 2 years after surgery were haemoglobin ≤ 10 g/dl and colon locations (HR 1.02; CI 0.51–2.02), ASA class of IV (HR 3.55; CI 1.91–6.58), residual tumour classification of R2 (HR 7.82; CI 3.11–19.62), TNM stage of III (HR 2.14; CI 1.23–3.72) or IV (HR 3.21; CI 1.47–7), LODDS of more than − 0.53 (HR 3.08; CI 1.62–5.86)) and complications during admission (HR 1.73; CI 1.07–2.80). Between 2 and 5 years of follow-up, the predictors were no tests performed within the first year of follow-up (HR 2.58; CI 1.21–5.46), any complication due to the treatment within the 2 years of follow-up (HR 2.47; CI 1.27–4.81), being between 85 and 89 and not having radiotherapy within the second year of follow-up (HR 1.60; CI 1.01–2.55), no colostomy closure within the 2 years of follow-up (HR 4.93; CI 1.48–16.41), medical complications (HR 1.61; CI 1.06–2.44), tumour recurrence within the 2 years of follow-up period (HR 3.19; CI 1.96–5.18), and readmissions at 1 or 2 years of follow-up after surgery (HR 1.44; CI 0.86–2.41). Conclusion We have identified variables that, in our sample, predict mortality 2 and between 2 and 5 years after surgery for colorectal cancer older patients. We have also created risks scores, which could support the decision-making process. Trial registration ClinicalTrials.gov, NCT02488161.

REDISSEC-CARESS/CCR group., [Introduction] Few studies have been conducted to establish the relationship between colorectal cancer screening programmes and survival adjusting by stage and, to determine whether there are differences, at a biological level, between the tumours of asymptomatic and symptomatic patients. Accordingly, the aim of this study is to evaluate clinical, biological and survival differences between symptomatic colorectal tumours and those detected by screening., [Study method] A prospective cohort study was performed of patients subjected to surgical intervention during the period 2010–2012, at different hospitals in Spain. In every case, clinical, pathological, biological and survival-related variables were obtained., [Results] A total of 2634 patients from the CARESS-CCR cohort were analysed; of these, 220 were diagnosed through screening. The asymptomatic patients were younger, had a higher Body Mass Index (BMI), a lower degree of perineural invasion and a less advanced T stage and nodular stage, and the tumour was frequently located on the right side of the colon. All of these differences were statistically significant. The serum tumour marker carbohydrate antigen 19.9 (CA 19.9) was found more frequently in the symptomatic patients (p, [Conclusions] The detection method employed influenced the survival of patients with colorectal cancer and there were no significant biological differences between the study groups., This research was partially supported by grants from REDISSEC (RD12/0001/0010 and RD16/0001/0006), Instituto de Salud Carlos III (PI 09/00910, PI 13/00013, PI 18/01181) and the European Regional Development Fund.

This study aims to assess the efficacy of hormone therapy in patients with severe gastrointestinal bleeding due to multiple angiodysplastic lesions.Between May 2010 and July 2017, we included 12 consecutive patients with anaemia or recurrent bleeding due to angiodysplasia who had been started on hormone therapy. The therapy given was a combination of levonorgestrel (between 0.10 and 0.25 mg) and ethinylestradiol (between 0.02 and 0.05 mg). We determined the mean number of transfusions required in the 6 months before and after the start of the treatment, as well as the mean haemoglobin levels, number of admissions for anaemia due to gastrointestinal bleeding and length of hospital stay in these periods.The mean age of patients included was 77.83 years old and 75% were male. The follow-up period after treatment initiation was 6 months. Of the 12 patients included, only one stopped the treatment owing to it not being effective. Overall, 83.3% of the patients reported subjective improvement. Furthermore, we found significant differences comparing before and after starting treatment regarding the mean number of transfusions (7±4.8 vs. 3.4±4.6; P=0.005), the mean haemoglobin levels (9.5±1.2 vs. 10.8±2.6; P=0.034) and the mean number of admissions (1.6±1.6 vs. 0.2±0.4; P=0.024). On the contrary, differences between pretreatment and post-treatment length of hospital stay were not significant.Hormone therapy is a potentially useful therapeutic tool in patients with refractory bleeding and anaemia due to angiodysplasia.

Introduction: The diagnosis or treatment of breast cancer is sometimes delayed. A lengthy delay may have a negative psychological impact on patients. The aim of our study was to evaluate the sociodemographic, clinical and pathological factors associated with delay in the provision of surgical treatment for localised breast cancer, in a prospective cohort of patients. Methods: This observational, prospective, multicentre study was conducted in ten hospitals belonging to the Spanish national public health system, located in four Autonomous Communities (regions). The study included 1236 patients, diagnosed through a screening programme or found to be symptomatic, between April 2013 and May 2015. The study variables analysed included each patient's personal history, care situation, tumour history and data on the surgical intervention, pathological anatomy, hospital admission and follow-up. Treatment delay was defined as more than 30 days elapsed between biopsy and surgery. Results: Over half of the study population experienced surgical treatment delay. This delay was greater for patients with no formal education and among widows, persons not requiring assistance for usual activities, those experiencing anxiety or depression, those who had a high BMI or an above-average number of comorbidities, those who were symptomatic, who did not receive NMR spectroscopy, who presented a histology other than infiltrating ductal carcinoma or who had poorly differentiated carcinomas. Conclusions: Certain sociodemographic and clinical variables are associated with surgical treatment delay. This study identifies factors that influence surgical delays, highlighting the importance of preventing these factors and of raising awareness among the population at risk and among health personnel.

Population screening has improved early diagnosis of colorectal cancer (CRC). Nonetheless, most cases are diagnosed in symptomatic patients. Faecal immunochemical testing has been recommended for assessing patients with lower gastrointestinal symptoms, but whether it improves patient survival is unknown. Our objective was to compare CRC survival in 50- to 69-year-olds between asymptomatic screen-detected patients and symptomatic patients by route to diagnosis. Methods: We identified all cases of CRC diagnosed in 50-to 69-year-olds between 2009 and 2016, in Donostialdea (Gipuzkoa, Spain). Three groups were created: 1-screen-detected CRC, 2-CRC detected in symptomatic patients after a positive faecal immunochemical test(FIT), and 3-CRC detected in symptomatic patients without a FIT or after a negative result. We analysed survival using the Kaplan-Meier method and log-rank tests. Results: Of 930 patients diagnosed with CRC, 433 cases were detected through screening and 497 in symptomatic patients, 7.9% after a positive FIT and 45.5% by other means. The 3-year CRC survival was significantly lower in group 3 (69.5%) than groups 1 (93%, p = 0.007) or 2 (87.5%, p = 0.02). The risk of death was lower in groups 1 (HR 0.42, 95% CI 0.30&ndash, 0.58) and 2 (HR 0.51, 95% CI 0.29&ndash, 0.87). Conclusion: Half of CRC cases in 50- to 69-year-olds are diagnosed outside screening. Use of the FIT as a diagnostic strategy in symptomatic patients may improve survival.

O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status has been considered a prognostic factor in newly diagnosed glioblastoma (GBM). In this study, we evaluated the prognostic and predictive value of MGMT promoter methylation in patients with glioblastoma in Donostia Hospital. Surprisingly, methylation of MGMT promoter did not predict response to temozolomide in patients with glioblastoma in Donostia Hospital. Specifically, overall survival (OS) and progression-free survival (PFS) did not differ significantly by MGMT methylation status in our cohort. In contrast, both were longer in patients who received treatment, received more TMZ cycles, had a better general status and perform at least a partial resection. No association was detected between methylation of MGMT promoter and molecular markers such as ATRX, IDH, p53 and Ki67. These results indicate that MGMT methylation did not influence in patient survival in our cohort.

Background There is already evidence that the faecal immunochemical test (FIT) is a useful tool for the diagnosis of colorectal cancer (CRC) that helps to identify symptomatic patients requiring early colonoscopy. Although the recommendation to use FIT is widely accepted, there are no data concerning whether this strategy improves patient survival.The objective was to assess whether the survival is higher if CRC patients have been first diagnosed by FIT (as compared with the rest of patients with CRC). Methods We identified all cases of CRC diagnosed between 2009 and 2016 in Donostialdea (Spain), excluding all the CRC detected in population screening. We focused on symptomatic patients. One thousand five hundred twenty-seven cases of CRC were divided into two groups based on the route to diagnosis: group 1: individuals who tested positive in a FIT during the year before diagnosis, and group 2: others.Survival was assessed by Kaplan-Meier estimation, and with the log-rank test. A Cox regression model was used to adjust for differences between groups due to other variables associated with survival. Results One thousand nine hundred sixty-seven cases of invasive CRC were identified, of which 22.4% were detected in population screening. Of the 1527 cases diagnosed in symptomatic patients, 317 patients had undergone a FIT in the year before the diagnosis of CRC. In 279 cases(18.3%), the result had been positive and this was the first step towards their CRC diagnosis (group 1). Group 2 was composed of the 1248 cases of CRC (81.7%). Considering these cases, 1210 patients with CRC did not undergo any FIT while 38 patients presented a negative result in the year before the diagnosis. The rate of early-stage disease (stage I or II) was higher in group 1 (51.3% vs 45.5% in group 2) (p = 0.04). Furthermore, the 3-year survival was longer in group 1 (72% vs 59% in group 2) (HR 1.50; 95% CI 1.22–1.84).The variables independently associated with worse survival were: group 2, age > 70 years and stage at the moment of diagnosis. Conclusions The use of FIT as a diagnostic strategy in symptomatic patients may improve survival in CRC. Nonetheless,FIT is still not widely used in our region.

Resumen Introduccion La condicion funcional fisica y psiquica son factores clave en la poblacion anciana. Hay disponibles muchas herramientas de evaluacion, pero no se pueden aplicar a la totalidad de la poblacion geriatrica. Presentamos el test Alusti, cuyas 2 versiones le permiten abarcar este amplio y complejo espectro de poblacion. Material y metodos Estudio prospectivo realizado con poblacion institucionalizada, hospitalizada y comunitaria, desarrollado entre septiembre y diciembre del 2016. Se ha realizado el analisis comparativo con otros test: indice de Barthel (IB), velocidad de la marcha (VM), Timed «UP & GO» test (TUG), Short Physical Performance Battery (SPPB) y test Tinetti. Resultados Se incluyeron 363 sujetos (edad media 83,25 anos), con diferentes niveles de situacion funcional y cognitiva. La aplicacion del test resulta sencilla, rapida (entre 3 y 6 min), con un 100% de aplicabilidad y usabilidad, con efecto suelo-techo amplio (0-100 puntos), con un coeficiente de correlacion intraclase (CCI) que muestra alta fiabilidad interobservador (CCI = 0,99) y buena correlacion en su version completa con el IB (CCI = 0,86; intervalo de confianza [IC]: 0,82-0,88) y el test Tinetti (CCI = 0,76; IC 95%: 0,71-0,81) asi como en la abreviada con IB (CCI = 0,71; IC 95%: 0,65-0,75) y con el test Tinetti (CCI = 0,90; IC 95%: 0,88-0,92). Permite medir la variacion de la situacion funcional, que en nuestra muestra ha generado un aumento del 10,9%, tras un periodo de hospitalizacion. Conclusiones El test Alusti permite la evaluacion del rendimiento fisico en la totalidad de la poblacion geriatrica. La mayor concordancia se produce con el test Tinetti, al que supera en aplicabilidad.

Background The overall aim of this study was to describe trends in participation rates and detection of lesions in a colorectal cancer (CRC) screening programme, during three rounds, using faecal immunochemical test (FIT). Methods National registers were used to collect data on invitations for CRC screening in the Basque Country (Spain) from 2009 to 2014. Information about participation, age, gender and lesions in each round were collected. Results A total of 961.533 individuals were included in the analysis; respectively, 584.950, 298.143 and 78.440 in the first, second and third rounds. The average participation rate was 68.4% (66.8, 70.4 and 72.3%, respectively by round; P < 0.001) and the positivity rate was 6.3% (7, 5.5 and 5.4%, respectively by round; P < 0.001). The participation rate increased significantly with age and was found to be higher in women versus men. A total of 15.144 advanced adenomas and 2.131 CRCs were diagnosed, leading to a detection rate of 23.9 and 3.4‰, respectively. Regarding gender, men had the highest rates in all periods and rounds. The detection rate of advanced neoplasia was lower in the regular when compared with irregular paricipants. Conclusions In a CRC screening, this organization obtained high FIT participation rates. Older participants and women were associated with a higher participation. The detection rate of lesions was higher in men, independent on age and round.

Introduction We present a case-control study of non-AIDS-defining cancers (NADCs) in a cohort of HIV-infected patients where we value the incidence, survival and prognostic factors of mortality. Methods All NADCs diagnosis conducted from 2007 to 2011 in 7 hospitals were collected prospectively, with a subsequent follow up until December 2013. A control group of 221 HIV patients without a diagnosis of cancer was randomly selected. Results Two hundred and twenty-one NADCs were diagnosed in an initial cohort of 7067 HIV-infected patients. The most common were: hepatocellular carcinoma 20.5%, lung 18.7%, head and neck 11.9% and anal 10.5%. The incidence rate of NADCs development was 7.84/1000 people-year. In addition to ageing and smoking, time on ART (OR 1.11; 95% CI 1.05–1.17) and PI use (OR 1.72; 95% CI 1.0–2.96) increased the risk of developing a NADC. During follow-up 53.42% died, with a median survival time of 199.5 days. In the analysis of the prognostic factors of mortality the low values of CD4 at tumour diagnosis (OR 0.99; 95% CI 0.99–1.0; p = 0.033), and the previous diagnosis of AIDS (OR 2.06; 95% CI 1.08–3.92) were associated with higher mortality. Conclusions Predictors of NADCs in our cohort were age, smoking, CD4 lymphocytes and time on ART. Mortality is high, with NADC risk factors being low CD4 count and previous diagnosis of AIDS.

Resumen Introduccion Presentamos un estudio caso-control de tumores no definitorios de sida (TNDS) en una cohorte de pacientes infectados por el VIH en la que valoramos las tasas de incidencia, supervivencia y factores pronosticos de mortalidad. Metodos Se recogieron de forma prospectiva en 7 hospitales, los diagnosticos de TNDS realizados de 2007 a 2011, con seguimiento posterior hasta diciembre de 2013. Se seleccionaron de forma aleatoria un grupo control de 221 pacientes VIH sin diagnostico de cancer. Resultados Se diagnosticaron 221 TNDS en una cohorte inicial de 7.067 pacientes VIH. Los mas frecuentes: hepatocarcinoma 20,5%, pulmon 18,7%, cabeza y cuello 11,9% y anal 10,5%. La tasa de incidencia de desarrollo de TNDS fue de 7,84/1.000 pacientes-ano. Ademas de la edad y el tabaco, el tiempo en TAR (OR 1,11; IC 95% 1,05-1,17) y el uso de IP (OR 1,72; IC 95% 1,0-2,96) aumentaron el riesgo de desarrollar un TNDS. Durante el seguimiento fallecieron el 53,42%, con una mediana de supervivencia de 199,5 dias. En el analisis de los factores pronosticos de mortalidad, los valores bajos de CD4 en el momento del diagnostico del tumor (OR 0,99; IC 95% 0,99-1,0; p = 0,033) y el diagnostico previo de sida (OR 2,06; IC 95% 1,08-3,92) se asociaron con una mayor mortalidad. Conclusiones Los predictores de TNDS en nuestra cohorte fueron la edad, el consumo de tabaco, los linfocitos CD4 y el mayor tiempo en TAR. La mortalidad es alta, siendo factores de riesgo los CD4 bajos en el momento del diagnostico del TNDS y el diagnostico previo de sida.

Purpose The delayed diagnosis of colorectal cancer (CRC) may be attributable to sociodemographic characteristics, to aspects of tumour histopathology or to the functioning of the health system. We seek to determine which of these factors most influences prolonged patient-attributable delay (PPAD) in the diagnosis and treatment of CRC. Materials and methods A prospective, multicentre observational study was conducted in 22 Spanish hospitals. In total, 1,785 patients were recruited to the study between 2010 and 2012 and underwent elective or urgent surgery. PPAD is considered to occur when the time elapsed between a patient presenting the symptom and him/her seeking attention from the primary care physician or hospital emergency department exceeds 180 days. A bivariate analysis was performed to assess differences in variables segmented by tumour location and patient delay. Multivariate logistic regression analysis was performed on the outcome variable, PPAD. Results The rate of PPAD among this population was 12.1%. PPAD was significantly associated with altered bowel rhythm (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.02 to 1.83) and with adenocarcinoma histology, in comparison with mucinous adenocarcinoma (OR, 2.03; 95% CI, 1.11 to 3.71). Other sociocultural factors and clinicopathological features were not independent predictors of PPAD. Conclusion Many patients do not consider altered bowel rhythm an alarming symptom, warranting a visit to the doctor. PPAD could be reduced by improving health education, raising awareness of CRC-related symptoms.

Resume Objectif Evaluer si l’âge a l’apparition du rhumatisme psoriasique (RP) facilite la caracterisation du phenotype de la maladie. Methodes Etude retrospective d’une cohorte de 205 patients consecutifs remplissant les criteres CASPAR du RP. Les resultats de l’etude ont ete evalues par des analyses univariees et multivariees en fonction de l’âge a l’apparition des atteintes cutanees et articulaires (seuil a 40 ans). Resultats Le psoriasis precoce a ete associe a une atteinte cutanee plus etendue (OR : 2,3, p = 0,011), un profil axial a l’apparition de la maladie (OR : 4,6, p = 0,009) et mixte au cours de l’evolution (OR : 2,4, p = 0,019), des antecedents familiaux de psoriasis (OR : 3,1, p = 0,003) et de RP (OR : 4,0, p = 0,021) et une prevalence plus elevee de HLA-C06 (OR : 2,03, p = 0,03) et HLA-B27 (OR : 2,7, p = 0,02). L’arthrite precoce s’est caracterisee par davantage d’antecedents familiaux de RP (OR : 2,9, p = 0,007) et par la presence de HLA-B27 (OR : 5,9, p Conclusion L’âge a l’apparition de la maladie a une forte influence sur plusieurs parametres du phenotype du RP. Il serait donc pertinent d’utiliser ce facteur descriptif comme option de stratification dans les etudes epidemiologiques et genetiques sur le RP.

Background There is conflicting evidence about what factors influence outcomes after total knee replacement (TKR). The objective is to identify baseline factors that differentiate patients who achieve both, minimal clinically important difference (MCID) and a patient acceptable symptom state (PASS) in pain and function, measured by WOMAC, after TKR from those who do not attain scores above the cutoff in either of these dimensions. Methods One-year prospective multicentre study. Patients completed WOMAC, SF-12, EQ-5D, expectations, other joint problems and sociodemographic data while in the waiting list, and 1-year post-TKR. Dependent variable was a combination of MCID and PASS in both dimensions (yes/no). Univariate analysis was performed to identify variables associated. Exploratory factor analysis (EFA) was performed to study how these variables grouped into different factors. Results Total sample comprised 492 patients. Mean (SD) age was 71.3 (6.9), and there were a 69.7% of women. Of the total, 106 patients did not attain either MCID or PASS in either dimension, and 230 exceeded both thresholds in both dimensions. In the univariate analysis, 13 variables were associated with belonging to one group or another. These 13 variables were included in EFA; 3 factors were extracted: expectations, mental health, and other joints problems. The percentage of variance explained by the 3 factors was 80.4%. Conclusion We have found 2 modifiable baseline factors, expectations and mental health, that should be properly managed by different specialist. Indication of TKR should take into account these modifiable factors for improving outcomes after TKR.

INTRODUCTION: The use of Peripherally Inserted Central Catheters (PICCs) has increased significantly in the last years due to their advantages compared to the other types of central catheters: easier and protocolized insertion by specialized nurse-led teams; cost-effectiveness; ease of management, ... However, an increase in the incidence of Catheter Related Thrombosis (CRT) has been observed with this type of device, especially in cancer patients and in the critical care setting. The main objective of this study is to determine the incidence of PICC related deep venous thrombosis in oncologic and onco-hematologic patients at the Donostia University Hospital, in Spain. The secondary outcome is the identification of possible risk factors associated with this event. METHODS: Using the database created and handled by the nurse-led Intravenous Therapy Team (ITT) in our center, in which all inserted PICCs are prospectively and consecutively included since 2011, a retrospective analysis was conducted on oncology and hemato-oncology-derived adult patients (over 18 years old) with a PICC inserted between May 15th 2018 and December 15th 2019. In the total population, several characteristics of the patient, of the PICC and of the thrombotic event were descriptively analyzed, and a bivariant analysis of four potential risk factors was carried out using Pearson's Chi-squared test. Patient and CRT treatment-associated risk factors were more exhaustively analyzed in the subgroup of patients with CRT. The missing data were obtained from the electronic clinical history records. RESULTS: The final study sample consisted of 1024 PICCs (n=1024), 19,10% (n=313) derived from the Hematology department and 43,62% (n=715) from the Oncology department (tables 1 and 2). The global incidence of CRT was 4,9% (n=50): 5.8% in hematologic patients and 4.5% in patients derived from Oncology. In the bivariant analysis no significant association was found between the selected potential risk factors (department of origin, PICC lumen number, PICC material and the catheter-to-vessel ratio) and CRT (table 3). In terms of the treatment administered to patients presenting CRT, in 80% of the cases (n=40) a Low Molecular Weight Heparin (LMWH) at therapeutic dose was initiated; in 10% (n=5) LMWH at a lower dose, and in 2 patients treatment could not be initiated because of thrombopenia. Finally, the PICC was withdrawn in only 8 patients after the diagnosis of the thrombotic event. CONCLUSIONS: The majority of the studies on PICC associated venous thrombosis in cancer patients are small, observational, retrospective, and without comparison groups. Here we present a work with an important sample size, a homogeneous population and with a prospective data collection. The CRT incidence has been similar to that described in the literature and significant association has not been found between the included potential risk factors and CRT. In conclusion, this study reflects the need of more trials on this subject, in particular to identify CRT risk factors in order to design effective prevention strategies.

Objective To identify factors associated with early, intermediate or late recurrence colon cancer recurrence. Methods A total of 1,732 consecutive patients with colon cancer were recruited and followed for a period of 5 years. Recurrence at 1 year (early), from 1 to 2 (early), from 2 to 3 (intermediate) and from 3 to 5 years (late) was the main outcome measures. Results Predictors of early recurrence (AUC (95% CI):0.74 (0.70–0.78) were as follows: TNM stage II and III, more than one type of invasion, haemoglobin

Objective The aim of this study was to explore the association between baseline social support, functional status, and change in health-related quality of life (HRQoL) in colorectal cancer patients and change in anxiety and depression measured by Hospital Anxiety and Depression Scale (HADS) at 1 year after surgery. Methods Consecutive patients who were due to undergo therapeutic surgery for the first time for colon or rectal cancer in 9 hospitals in Spain were eligible for the study. Patients completed the following questionnaires before surgery and 12 months afterward: 1 HRQoL instrument, the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire; a social support questionnaire, the Duke-UNC Functional Social Support Questionnaire; the Barthel Index, to assess functional status; the HADS, to assess anxiety and depression; and questions about sociodemographic information. General linear models were built to explore the association between social support, functional status, and change in HRQoL and changes in anxiety and depression 12 months after surgery. Results A total of 947 colorectal cancer patients took part in the study. Patients' functional status, social support, and change in HRQoL were associated with changes in anxiety and depression. Greater social support and improvements in physical, cognitive, and social functioning and in insomnia resulted in improvements in anxiety and depression. No functionally independent patients were associated with lesser improvements in anxiety and depression. Conclusions Colorectal cancer patients who have more social support, are functionally independent and have higher improvements in HRQoL may have better results in anxiety and depression at 1 year after surgery, adjusting for age, gender, location, occupation, and baseline HADS scores.

AIM: To compare intraoperative phacoemulsification parameters and its effect on the corneal endothelium of eyes undergoing femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification (CP) cataract surgery. METHODS: Two hundred eyes from one hundred patients were included in a prospective, non-blinded, randomized, controlled, intraindividual clinical study. One hundred eyes underwent FLACS while their one hundred fellow eyes underwent CP. All surgeries were performed using the Victus® femtosecond laser platform and Infinity® Vision System phacoemulsification machine. Primary outcome measure was endothelial cell density 6mo after surgery. Secondary outcome measures included central corneal thickness (CCT), average cell area, standard deviation, coefficient of variation and hexagonality before surgery and 6mo after surgery and endothelial cell density loss during this period were also evaluated. Intraoperative efficiency parameters [cumulative dissipated energy (CDE), total intraocular surgery time, total ultrasound time, total phacoemulsification time, total torsional energy time, total aspiration time, ultrasound energy, torsional amplitude and fluid required during surgery] were also collated. RESULTS: Data from these patients was not considered for analysis. Data from 92 patients were analysed. Postoperative endothelial cell density (cells/mm2) between groups (2211.88±392.49 CP; 2246.31±403.48 FLACS) was not statistically significant (P=0.869). Total ultrasound time, torsional energy time, CDE and fluid requirements were significantly lower the FLACS group (P

Long non-coding RNAs (LncRNAs) have emerged as a relevant class of genome regulators involved in a broad range of biological processes and with important roles in tumor initiation and malignant progression. We have previously identified a p53-regulated tumor suppressor signature of LncRNAs (PR-LncRNAs) in colorectal cancer. Our aim was to identify the expression and function of this signature in gliomas. We found that the expression of the four PR-LncRNAs tested was high in human low-grade glioma samples and diminished with increasing grade of disease, being the lowest in glioblastoma samples. Functional assays demonstrated that PR-LncRNA silencing increased glioma cell proliferation and oncosphere formation. Mechanistically, we found an inverse correlation between PR-LncRNA expression and SOX1, SOX2 and SOX9 stem cell factors in human glioma biopsies and in glioma cells in vitro. Moreover, knock-down of SOX activity abolished the effect of PR-LncRNA silencing in glioma cell activity. In conclusion, our results demonstrate that the expression and function of PR-LncRNAs are significantly altered in gliomagenesis and that their activity is mediated by SOX factors. These results may provide important insights into the mechanisms responsible for glioblastoma pathogenesis.

To identify and validate risk factors that contribute to prolonged length of hospital stay (LOS) in patients undergoing resection for colorectal cancer. This prospective cohort study included 1955 patients admitted to 22 hospitals for primary resection of colorectal cancer. Multivariate analyses were used to identify and validate risk factors, randomizing patients into a derivation and a validation cohort. Multiple correspondence and cluster analysis were performed to identify clinical subtypes based on LOS. The strongest independent predictors of prolonged LOS were postoperative reintervention, surgical site infection, open surgery, and distant metastasis. The multiple correspondence and cluster analysis provided three groups of patients in relation to prolonged LOS: patients with the longest LOS included the highest percentage of patients with open surgery, distant metastasis, deep surgical site infections, emergency admissions, additional diagnostic factors, and highly contaminated surgical sites. Patients with prolonged LOS (> 14 days) were more likely to develop adverse outcomes within 30 days after discharge. Patients undergoing resection of colorectal cancer cluster into different groups based on LOS of the index admission. Those with prolonged LOS were more likely to develop adverse outcomes within 30 days after discharge. Some of the strongest independent predictors of prolonged LOS, such as surgical infections or open surgery, could be modified to reduce LOS and, in turn, other adverse outcomes. NCT02488161

Background Aspirin (ASA) is a drug that can cause gastrointestinal lesions and symptoms. Colorectal cancer (CRC) is the most prevalent type of cancer in Western countries. We assessed the effect of aspirin on the diagnostic accuracy of the faecal immunochemical test (FIT) for CRC and/or advanced neoplasia (AN) in patients undergoing colonoscopy for gastrointestinal symptoms. Methods We conducted a prospective multicentre observational study of diagnostic tests that included patients with gastrointestinal symptoms undergoing colonoscopy between March 2012 and 2014 (the COLONPREDICT study). Symptoms were assessed and a FIT and blood tests assessing haemoglobin and carcinoembryonic antigen (CEA) levels were performed. Results The study included 3052 patients: A total of 2567 did not take aspirin (non-user group) and 485 (16%) took aspirin (user group). Continuous treatment with ASA did not change the AUC (0.88, 0.82; p = 0.06), sensitivity (92%, 88%; p = 0.5) or specificity (71%, 67%; p = 0.2) of the FIT for CRC detection. Similarly, we found no differences in the AUC (0.81, 0.79; p = 0.6), sensitivity (74%, 75.5%; p = 0.3) or specificity (76%, 73.6%; p = 0.3) for AN detection. Patients with an aspirin use of ≥ 300 mg/day had a lower prevalence of AN and the sensitivity, specificity and AUC for AN for these patients were 54%, 68% and 0.66, significantly lower than for the non-user group ( p = 0.03). Conclusions Aspirin does not modify the diagnostic accuracy of FIT for CRC and/or AN in patients with gastrointestinal symptoms. Aspirin use of ≥ 300 mg/day decreases the accuracy of the test.

Background The objective of this study was to study motor and nonmotor symptoms and striatal dopaminergic denervation, as well as the relationship between them, in a cohort of asymptomatic relatives of patients with Parkinson's disease (PD) with the R1441G-leucine-rich repeat kinase 2 mutation. Methods Asymptomatic relatives of patients with PD and this mutation were tested for the presence of the mutation and evaluated for striatal, putamenal, and caudate dopaminergic transporters using 123I-2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl)-nortropane single-photon emission computed tomography binding ratios. Clinical and neuropsychological evaluations including timed motor tests, a smell identification test, and global cognition, attention, executive, visuospatial, and memory functions as well as depression, constipation, and rapid eye movement sleep behavior disorder were also assessed. Results Twenty-seven carriers and 19 noncarriers were studied. Compared with noncarriers, mutation carriers had significantly lower 123I-2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl)-nortropan mean striatal (P = 0.03), mean putamenal (P = 0.01), and lowest putamenal (P = 0.01) binding ratios. Multiple linear regression analysis showed that the carrier status and the execution of timed tests significantly predicted striatal 123I-2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl)-nortropane binding. The proportion of variation accounted for by the regression model of these variables was 69% for the putamen and 53% for the caudate nucleus. Conclusions Asymptomatic carriers of the R1441G-leucine-rich repeat kinase 2 mutation have evidence of dopaminergic nigrostriatal denervation, mainly in the putamen, which is associated with a decline in the execution of complex motor tests. These tests could be early indicators of the ongoing dopaminergic deficit in this group at risk of PD. © 2015 International Parkinson and Movement Disorder Society

Background The aim of this study was to explore the association of social support received, and functional and psychological status of colorectal cancer patients before surgery with changes in health-related quality of life (HRQoL) outcomes measured by EORTC QLQ-C30 at 1-year post-intervention. Methods Consecutive patients that were because of undergo therapeutic surgery for the first time for colon or rectum cancer in nine hospitals in Spain were eligible for the study. Patients completed questionnaires before surgery and 12 months afterwards: one HRQoL instrument, the EORTC QLQ-C30; a social network and social support questionnaire, the Duke-UNC Functional Social Support Questionnaire; the Hospital Anxiety and Depression Scale, to assess anxiety and depression; and the Barthel Index, to assess functional status; as well as questions about sociodemographic information. General linear models were built to explore the association of social support, functional status, and psychological variables with changes in HRQoL 12 months after intervention. Results A total of 972 patients with colorectal cancer took part in the study. Patients' functional status, social support, and anxiety and depression were associated with changes in at least one HRQoL domain. The higher functional status, and the higher social support, the more they improved in HRQoL domains. Regarding anxiety and depression, the more anxiety and depression patients have at baseline, less they improve in HRQoL domains. Conclusions Patients with colorectal cancer who have more social support and no psychological distress may have better results in HRQoL domains at 1 year after surgery.

The goal of this study was to compare the effectiveness of laparoscopic with that of open surgery up to 2 years after intervention in patients with rectal cancer. This is a prospective cohort study of patients with rectal cancer who underwent surgery (laparoscopic or open) between June 2010 and December 2012 in 22 acute hospitals. Main outcomes were mortality, complications, reoperation, readmission, and patient-reported outcome measures (PROMs), as measured using the EuroQol-5D (EQ-5D), European Organisation for Research and Treatment of Cancer (EORTC) QLQ-Q30 and Q29, the Barthel Index (BI), and the Duke-UNC Functional Social Support Questionnaire at baseline, 1 year, and 2 years after surgery. Multivariable multilevel logistic regression and generalized linear models were used in the analyses after adjusting for specific propensity scores developed for each outcome and time point. In the multivariable analysis, rates of some medical complications after surgery during admission (renal failure and paralytic ileus) and infectious (urinary tract infection, septic shock, and localized intra-abdominal infection) and at 1 year (renal and heart failure) were higher among patients who underwent open surgery than among those who underwent laparoscopic surgery. There were no differences between the two surgical approaches in all other parameters assessed at the different time points or in all PROMs evaluated. Laparoscopic surgery and open surgery provide quite similar results in patients with rectal cancer up to 2 years after intervention in most outcomes, though the rates of certain medical and infectious complications at admission and up to 1 year after the intervention were higher in open surgery.

Physical and psychological functional conditions are key factors in the elderly population. Many evaluation tools are available, but they cannot be applied to the whole geriatric population. The use Alusti Test is presented. This test consists of 2versions, which enable it to encompass this wide and complex population spectrum.A prospective study with the institutionalised, hospitalised, and community population, was conducted between September and December 2016. A comparative analysis was conducted using the Barthel Index (BI), Gait Speed Test (GST), Timed «UpGo» Test (TUG), Short Physical Performance Battery (SPPB), and Tinetti Test.A total of 363 subjects were enrolled (mean age: 83.25 years), with varying levels of functional and cognitive conditions. The test was simple and quick to apply (3-6min), 100% applicable and usable with broad floor and ceiling effects (0-100 points) with an intraclass correlation coefficient (ICC) that shows a high inter-observer reliability (ICC = 0.99), and a good correlation in its full version with BI (ICC = 0.86) (95% CI: 0.82-0.88), and the Tinetti test (ICC = 0.76; 95% CI: 0.71-0.81), as well as in the abbreviated version BI (ICC = 0.71; 95% CI: 0.65-0.75) and Tinetti Test (ICC = 0.90; 95% CI: 0.88-0.92). This allows the variation of the functional condition to be measured, which in our sample showed an increase of 10.9%, after a period of hospital admission.It is considered that Alusti test meets the requirements for physical performance assessment in the whole the geriatric population. The highest level of accuracy is given by the Tinetti test, which has greater applicability.
