Abstract: Objetivos: Determinar las propiedades métricas del EUROQoL y optimizar las del COOP/WONCA en personas con osteoartrosis de cadera o rodilla. Además, se pretende conocer la validez convergente entre ambos cuestionarios. Material y Método: Estudio descriptivo transversal realizado en los Hospitales "La Merced" (Osuna-Sevilla) y "Torrecárdenas" (Almería), mediante encuesta telefónica, incluyendo todas las personas en espera de artroplastia de cadera o rodilla por osteoartrosis, desde octubre 2004 hasta noviembre de 2006. Resultados: El COOP/WONCA presentó un máximo de 79,9% de frecuencia de endose. El análisis factorial por componentes principales desechó 2 ítems con valores inferiores a 0,5; logrando la mayor varianza total explicada 71,09% de CVRS, con dos componentes de 50,70% y 20,38%. Se realizó una rotación Promax, dada la correlación de factores (0,36). En fiabilidad obtuvo un a de Cronbach de 0,75. El EUROQoL presentó una frecuencia de endose de 96,8% para el ítem de movilidad. El análisis factorial por componentes principales encontró una varianza total explicada del 59,46%; con dos factores con 36,77% y 22,68%. La correlación de factores inferior a 0,2 determinó la rotación Varimax. La fiabilidad obtuvo un a de Cronbach de 0,53. El análisis de convergencia entre ambos cuestionarios mostró una baja correlación. Conclusiones: El COOP/WONCA con 5 ítems presenta unas propiedades métricas adecuadas, convirtiéndolo en instrumento de elección para medir la CVRS en población con osteoartrosis de cadera y rodilla, a diferencia de las insatisfactorias propiedades del EUROQoL. Ambos cuestionarios no presentan una convergencia de contenido suficientemente similar para usar las tablas de a os ajustados por calidad de vida del EUROQoL con el COOP/WONCA. Objectives: To determine the metric properties of EUROQoL and to optimize the metric properties of COOP/WONCA on people suffering from hip and knee osteoarthritis, via telephone. Also to identify the convergence validity between them. Methods: A descriptive study design is performed at "La Merced" (Osuna-Sevilla) and "Torrecárdenas" (Almería) Hospitals, via telephone interview since October 2004 to November 2006. The study included all people suffering from hip and knee osteoarthritis and awaiting for a surgical intervention. Results: COOP/WONCA obtained a maximum value of 79,9% on endorsement frequency. Main components factorial analysis resulted on two items with a value below 0,5; and the greatest explained total variance -71,09%- of Health Related Quality of Life (HRQoL) with two components of 50,70% and 20,

Abstract: Objective: To identify the factors associated with Health Related Quality of Life (HRQL), and Symptoms and Physical Functional Disability (S&PFD) after a Hip or Knee Total Replacement, according to a gender approach. A longitudinal cohort study design is performed at “La Merced” (Osuna. Sevilla) and “Torrecárdenas” (Almería) Hospitals, via telephone interview since October 2004 to November 2006. The study included all people who underwent a hip or knee total replacement. The dependent variables were HRQL and S&PFD, both measured via short versions of the COOP/WONCA and WOMAC questionnaires.Results: 311 people were included, who were mostly women (82,63%) and 70 years old (average). The hip and knee replacement obtained an statistically significant improvement on HRQL (20,5%) and S&PFD (28,2%), with no gender difference. Five variables were associated to HRQL for Women: HRQL previous to surgery, hospital, local infection as a complication, autonomy for daily living, and marital status. All of them were associated to men, except the last two ones. About S&PFD, six variables were associated for women: HRQL and S&PFD previous to surgery, hospital, local infection as a complication, body mass index and marital status. All of them were associated to men, except the last two ones.Factors associated to improve on HRQL and S&PFD in male population are few, though they find a great explanation of the improvement. Different situation arise on female population because more factors obtained a substantially inferior explanation.

Abstract: We conducted a meta-analysis to assess the association between the N363S polymorphism of the GRL gene and obesity risk. In addition to published research, we included also our own unpublished data -three novel case-control studies- in the meta-analysis The new case-control studies were conducted in German and Spanish children, adolescents and adults (total number of subjects: 1,117). Genotype was assessed by PCR-RFLP (Tsp509I). The final formal meta-analysis included a total number of 5,909 individuals.The meta-analysis revealed a higher body mass index (BMI) with an overall estimation of +0.18 kg/m2 (95% CI: +0.004 to +0.35) for homo-/heterozygous carriers of the 363S allele of the GRL gene in comparison to non-carriers. Moreover, differences in pooled BMI were statistically significant and positive when considering one-group studies from the literature in which participants had a BMI below 27 kg/m2 (+ 0.41 kg/m2 [95% CI +0.17 to +0.66]), but the differences in BMI were negative when only our novel data from younger (aged under 45) and normal weight subjects were pooled together (-0.50 kg/m2 [95% CI -0.84 to -0.17]). The overall risk for obesity for homo-/heterozygous carriers of the 363S allele was not statistically significant in the meta-analysis (pooled OR = 1.02; 95% CI: 0.56–1.87).Although certain genotypic effects could be population-specific, we conclude that there is no compelling evidence that the N363S polymorphism of the GRL gene is associated with either average BMI or obesity risk.Since 1990, important efforts have been made to identify genes influencing complex traits, often by relying on the use of a priori selected candidate genes. According to the updated 2004 version of the Human Obesity Map, 113 candidate genes showed initial association with obesity, out of which only 18 genes are supported by at least five positive studies [1-3]. Since both excess glucocorticoid secretion and central obesity are clinical features of some obese patients, it is

Abstract: objectives: to validate the ability of a hospital administration data set (minimum data set [mds]) to detect incident cases of colorectal cancer using the murcia cancer registry (mcr) as the gold standard and to measure agreement between the mds and registration of colorectal cancer. material and method: a cross sectional validation study of the mds of the main hospital in the region of murcia (spain) was conducted. the study population consisted of incident cases of colorectal cancer in 2000 obtained from the mcr and cases in the mds of the above-mentioned hospital for the same year with an icd-9 diagnostic code between 153.0 and 154.1, eliminating readmissions. during the process, two analyses were performed: one analysis with the principal diagnosis only and another with all the diagnostic codes. sensitivity, specificity, positive predictive value (ppv), negative predictive value (npv) and agreement was calculated with their 95% confidence intervals (ci). results: with the first diagnosis only, the mds detected 80% of the incident cases of colorectal cancer with a ppv of 75%. with all the diagnoses, the mds detected 85% of the cases with a ppv of 64%. the agreement in codification was high at three digits (kappa 88% (95% ci, 0.79-0.97) first diagnosis, 89% (95% ci, 0.80-0.97) all diagnoses) as well as at four digits (kappa 77% (ic, 0.68-0.85) first diagnosis, 78% (95% ci, 0.70-0.86) all diagnoses) in both analyses. conclusions: because of its high sensitivity, the mds is a good source for detecting incident cases of cancer. the high agreement found in the site of colorectal cancer helps to consolidate the mds as a data source for cancer registration.

Abstract: objectives: to quantify anxiety and immediate and late pain, efficacy of the common analgesic methods, and complications. methods: 117 patients were randomized to three groups: 1(39): lubricant gel; 2 (38): intrarectal lidocaine gel; 3 (40): anesthetic blockage with 1% lidocaine. complications and immediate and late pain were collected, these latter with a visual analogic scale. results: 70% of the patients were not much anxious. we did not find significant differences between the analgesia achieved in group 1 (4.37± 2.41) and group 2 (4.22± 2.46), but we found with group 3 (1.88± 2.03). mean pain score the afternoon after biopsy was lower in group 3 (2.08± 2.28) than in groups 1 and 2 (4.06± 2.80 and 2.42± 2.03), without statistical significance. the patients did not show a difference in pain during the pass of the transrectal transducer, varying between 2.34 for group 3 and 3.38 for group 2. grouped by sphincter tone we find differences (low 2.71± 2.76, medium 3.23± 2.38, high 4.99+- 2.22). patients feeling very nervous before the test had a pain score of 4.98± 2.57, significantly greater than the pain of those not feeling nervous (2.59± 2.21). we did not find differences in complications between the three groups. conclusions: the use of intrarectal lidocaine gel did not demonstrated being more effective in pain control in our series than the use of lubricant gel, but lidocaine injected into the apex and seminal vesicles was. sphincter tone and pre-test anxiety are the most determinants factors for pain.
