RESUMEN
AIM: The temporal avascular area of the retina and the duration of mechanical ventilation (DMV) may predict the need to treat retinopathy of prematurity (ROP). This study considers whether the rate of retinal vascularisation and related risk factors should be included in a predictive model of the need for ROP treatment. METHODS: This single-centre, observational retrospective case-control study was conducted on 276 preterm infants included in an ROP screening programme. All had undergone at least three examinations of the fundus. The main outcome measures considered were DMV (in days of treatment), the temporal avascular area (in disc diameters, DD) and the rate of temporal retinal vascularisation (DD/week). RESULTS: The multivariate logistic model that best explains ROP treatment (R2 = 63.1%) has three significant risk factors: each additional day of mechanical ventilation (OR, 1.05 [95% CI, 1.02-1.09]; p = 0.001); each additional DD of temporal avascular area (OR, 2.2 [95% CI, 1.7-2.9]; p < 0.001) and a vascularisation rate <0.5 DD/week (OR, 19.0 [95% CI, 6.5-55.5]; p < 0.001). Two tables are presented for calculating the expected need for ROP treatment according to these three risk factors. CONCLUSIONS: A greater DMV, a broad avascular area of the temporal retina at the first binocular screening and slow retinal vascularisation strongly predict the need for ROP treatment. The predictive model we describe must be validated externally in other centres.
RESUMEN
PURPOSE: To assess if a panel of cell-cycle markers could improve the discrimination of European Organization for Research and Treatment of Cancer (EORTC) and Spanish Urological Club for Oncological Treatment (CUETO) models in predicting recurrence and progression of high-grade non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND METHODS: Between January 2007 and January 2012, every patient with high-grade NMIBC treated with transurethral resection of bladder underwent immunohistochemical staining for 5 biomarkers (p21, p27, p53, KI-67, and cyclin E1). We excluded patients who had muscle-insvasive disease, underwent early cystectomy, and those with incomplete follow-up. Kaplan-Meier curves assessed recurrence and progression-free survival. Univariate and multivariate Cox regression analysis assessed the predictive ability of markers after correcting for EORTC or CUETO risk scores. Harrel concordance index assessed for discrimination. RESULTS: There were 131 patients with a median follow-up of 31.1 months. Stage was Ta (50%), T1 (44%), and Tis (8%). For 95 patients this was the primary tumor. Intravesical therapy was used in 76% of cases of which 45% had maintenance. Recurrence-free survival rates at 6, 12, and 24 months were 68.9%, 52.1%, and 33.2%, respectively, whereas progression-free survival rate at 6, 12, and 24 months were 93.8%, 88%, and 84.3%, respectively. No differences in survival based on number of altered markers were noted. Biomarker status was neither a significant predictor of recurrence nor progression. Marker alterations marginally improved discrimination of EORTC and CUETO models, which were confirmed to be mediocre. CONCLUSIONS: Markers were not significant predictors of recurrence nor progression in patients with high-grade NMIBC and their addition to prediction models is of little benefit.

Introducción: con el desarrollo de la sociedad y los cambios en el estilo de vida, las enfermedades cardiovasculares son la primera causa de muerte en el mundo y en Cuba. Son prevenibles si se actúa sobre sus factores de riesgo cardiovasculares, que se estratifican estimando el riesgo cardiovascular global. Se engloba los principales factores en tablas, que determinan la probabilidad de presentar una enfermedades cardiovasculares en 5 o 10 años. La edad vascular se calcula a partir del riesgo cardiovascular global. Es una herramienta útil para motivar a los pacientes a eliminar los factores de riesgo cardiovasculares. Por lo anterior, los autores se propusieron revisar referentes teóricos del riesgo cardiovascular global y la edad vascular. Materiales y métodos: se desarrolló una búsqueda en la Biblioteca Virtual de Infomed. Fueron revisados 231 trabajos científicos sin limitación de año y país, seleccionándose 49. Desarrollo: se caracterizaron 14 tablas que calculan el riesgo cardiovascular global, a partir del estudio de Framingham. En Cuba, fueron utilizadas las clásicas de Framingham, Organización Mundial de la Salud, Sociedad Internacional de Hipertensión y Gaziano sin laboratorio. La edad vascular de un individuo, es igual a la edad que tendría una persona con igual riesgo cardiovascular global, pero con todos los factores de riesgo cardiovasculares en niveles normales. Esto tiene una gran carga emocional que conlleva a que el paciente tome medidas preventivas. Conclusiones: las tablas que estratifican el riesgo cardiovascular global, deben ser ajustadas a la realidad epidemiológica de cada país. De las tablas utilizadas en Cuba, la de Gaziano sin laboratorio es la más factible de aplicar. La edad vascular es una forma fácil de comunicar el riesgo de sufrir unas enfermedades cardiovasculares.
Background: with the society development and changes in life style, cardiovascular diseases are the first cause of death in the world and in Cuba. They could be preventable if acting on their cardiovascular risk factors that are stratified estimating the global cardiovascular risk. The main factors are summed up in tables, determining the possibility of presenting a cardiovascular disease in 5 or 10 years. Cardiovascular age is calculated on the basis of the global cardiovascular risk. It is a useful tool for motivating patients to eliminate the cardiovascular risk factors. For all the before said, the authors planed to review theoretical referents of the global cardiovascular risk and the vascular age. Materials and Methods: it was carried out a search in the Virtual Library of Infomed. 231 works were reviewed without year or country limitation, selecting 49 of them. Development: there they were characterized 14 tables calculating the global cardiovascular risk factor, beginning from Framinghan study. In Cuba, it were used the classic ones of Framinghan, World Health Organization, International Society of Hypertension and Gaziano without laboratory teats. An individual’s vascular age is the same as it would be the age of a person with one and the same global vascular risk, but with all the cardiovascular risk factors at normal levels. This has a great emotional load leading the patient to take preventive measures. Conclusions: the tables stratifying the global cardiovascular risk should be adjusted to the epidemiologic reality of each country. Of all the tables used in Cuba, Gaziano´s without laboratory test is the most workable one. Vascular age is an easy form of communicating the risk of suffering cardiovascular diseases.
RESUMEN
INTRODUCTION: Due to the risk of recurrence and progression, patients with non-muscle-invasive bladder cancer have to be under observation. The aim of this study is the evaluation of early recurrence at the first control cystoscopy, as a prognostic factor for recurrence and progression based on EORTC risk tables. MATERIAL AND METHODS: This study analyzed 243 patients with non-muscle-invasive bladder cancer, with an average observation time of 46 months. Recurrence was observed in case of 99 patients. Among these patients, we selected 79 who had the first cystoscopy 3 months after the transurethral electroresection of the bladder tumor. Subsequently, 45 patients with early recurrence at the first control cystoscopy were compared with 34 patients whose cancer recurred at later control cystoscopies. The patients were compared with respect to the number of points assigned by EORTC tables. RESULTS: Those patients who had an early recurrence had a significantly higher score in the EORTC table in the progression scale (p = 0.017) but not in the recurrence scale (p = 0.11), as compared with patients who had a late recurrence. CONCLUSIONS: Early recurrence that occurs within 3 months after TURBT indicates a higher risk of progression, as compared with a late recurrence. Patients who had an early recurrence had a significantly higher EORTC risk score for progression. Their EORTC risk score for recurrence was also higher, but the difference was not statistically significant. Every patient with an early recurrence has a worse prognosis and a higher risk of progression.
RESUMEN
BACKGROUND: The aim of this study was to develop a risk stratification of patients with muscle-invasive bladder cancer (MIBC) after radical cystectomy (RC). For this purpose, we compared the cancer-specific mortality (CSM) of patients with primary MIBC and patients with secondary MIBC in different risk groups according to the European Organisation for Research and Treatment of Cancer (EORTC) progression score. PATIENTS AND METHODS: The records of 521 consecutive patients treated with RC for clinical MIBC according to transurethral resection of bladder cancer (TURBT) diagnosis were reviewed. Of the 521 patients, 399 (76.6%) had primary MIBC (study group 1 [SG1]) and 122 (23.4%) had secondary MIBC (study group 2 [SG2]). Patients in SG2 were stratified into risk groups according to the results of the first and last TURBT in non-MIBC using the EORTC progression score. RESULTS: CSM for patients with primary and secondary MIBC did not differ significantly. Patients in SG2 with the highest risk for tumor stage progression at time of the first and last TURBT in non-MIBC showed a significantly higher CSM after RC compared with patients with low-to-intermediate risk and compared with patients in SG1. In multivariable analyses, stage pT 3/4 (hazard ratio [HR], 2.12; P < .001), lymphovascular invasion (LVI) (HR, 3.47; P < .001), female sex (HR, 1.35; P = .048), and time from diagnosis of MIBC to RC > 90 days (HR, 2.07; P < .001) were significantly associated with higher CSM. CONCLUSION: Risk stratification by the EORTC progression score can help to identify those patients with the highest risk of CSM after progression to MIBC and thus enable us to offer these patients a multimodal treatment. Our results need to be verified in large prospective studies.

Objetivo: determinar cuál de las tablas de riesgo cardiovascular y factores de riesgo, está más relacionada con la resistencia a la insulina en los adultos sobrepesos y obesos. Métodos: se estudiaron 350 pacientes sobrepesos u obesos de edades comprendidas entre los 19 y 70 años. Se les aplicó un cuestionario, que incluyó: edad, sexo, color de piel, hábitos tóxicos, práctica de actividad física y medicamentos utilizados. Las particularidades del examen físico realizado fueron: peso, talla, índice de masa corporal, tensión arterial, circunferencias de cintura y cadera e índice cintura-cadera. Los exámenes bioquímicos realizados fueron: glucosa, insulina, colesterol, triglicéridos y HDL-c en ayunas. La resistencia a la insulina fue evaluada mediante el índice de cálculo modelo homeostático de Mathews. Se utilizaron las tablas de Framingham, de la Organización Mundial de la Salud y las de Gaziano para medir el riesgo cardiovascular. Resultados: al comparar la frecuencia de riesgo cardiovascular según las tablas utilizadas, se observó que el riesgo moderado y alto, según Gaziano, fue superior al encontrado por Framingham y la Organización Mundial de la Salud (20,6 por ciento [72/350] vs. 2,9 por ciento [10/350] y 3,7 por ciento [13/350]). La frecuencia de resistencia a la insulina se distribuyó de manera similar para todas las tablas de riesgo cardiovascular. Cuando se analizó la relación entre la resistencia a la insulina y cada factor de riesgo cardiovascular, predominaron los triglicéridos elevados (68,7 por ciento), seguido por el colesterol ³ 5,2 mmol/L (60,2 por ciento), el índice de masa corporal ³ 30 (59,0 por ciento) y la hipertensión (59,5 por ciento).

Objective: to determine the cardiovascular risk and risk factor table that is most associated with the insulin resistance in overweight and obese patients. Methods: three hundred fifty overweight and obese patients, aged 19 to 70 years, were studied. They were questioned about age, sex, race, toxic habits, physical exercising and pharmaceutical consumption. The details of the physical exam included weight, size, body mass index, blood pressure, waist and hip circumference, waist-hip index. The biochemical exams were glucose, insulin, cholesterol, triglycerides and HDL-C on fasting. Mathews' homeostatic model estimation index served to evaluate the insulin resistance. The WHO table, the Framingham table and Gaziano table sere used to measure the cardiovascular risk. Results: the comparison of the cardiovascular risk frequency according to the tables showed that the moderate and the high risks in Gaziano table were higher than those of the Framingham and of the World Health Organization (20.6 percent [72/350] vs. 2.9 percent [10/350] and 3.7 percent [13/350]). The insulin resistance frequency was similar in all the cardiovascular risk tables. In the analysis of the relations between the insulin resistance and each cardiovascular risk factor, increased triglyceride indexes prevailed (68.7 percent) followed by cholesterol index of ³ 5.2 mmol/L (60.2 percent), body mass index of ³ 30 (59.0 percent) and hypertension (59,5 percent). The sensitivity of detection of insulin resistance observed in each cardiovascular risk table was similar; however, Gaziano tables showed higher specificity (43 percent).

As to the sensitivity and specificity of the insulin resistance for each cardiovascular risk factor, the body mass index of ³ 30 yielded the highest specificity (74.5 percent). Conclusions: it is advisable to use Gaziano tables because they detected a higher number of individuals with cardiovascular risks, in addition to their higher specificity to detect subjects with insulin resistance. Obesity and hypertriglyceridemia were the cardiovascular risk factors most associated to the insulin resistance, so they should be taken into account to start therapeutic intervention in order to prevent the onset of some cardiovascular diseases(AU)

INTRODUCTION: The assessment of risk of recurrence and progression of bladder cancer (BC) is still rather difficult. We decided to check the rates of the changes mentioned above in the group of the Polish patients after a year-long observation and next to compare them with the results calculated in the European Organisation of Research and Treatment of Cancer (EORTC) risk tables. METHODS: The tested group consisted of 91 patients who underwent transurethral resection of bladder tumour (TURBT). When being diagnosed, 60 cases were in the pTa clinical stage, whereas 30 cases were in T1. The coexisting carcinoma in situ (CIS) was observed in four cases. On the basis of the scores obtained from the EORTC tables, the patients were divided into the groups of low, intermediate or high risk of disease recurrence and progression. RESULTS: Recurrence was noticed in 23 patients (25%), while progression was observed in 11 patients (12.1%). The rate of the observed recurrences proved to be lower than it had been predicted in all the groups, except for one of the intermediate-risk group (score 1- 4). Moreover, the rate of the progressions predicted according to the EORTC risk tables was higher in all the risk groups. CONCLUSIONS: It can be noticed that the rate of real recurrences is lower than expected, whereas the rate of the observed progressions is overestimated. Partly, it could be the result of using a relatively small group of patients for observation and applying a different method of treatment.
RESUMEN
Objective To evaluate the feasibility of European Organization for Research and Treatment of Cancer (EORTC) risk tables in non-muscle invasive bladder cancer in Chinese patients.Methods A retrospective analysis was performed on the data from 185 patients with non-muscle invaaive urothelial bladder cancer from January 2003 to February 2009. Among the 185 patients, 128 patients were stage Ta compared with 57 patients who were stage T1. There were 87, 53 and 45 patients with grade G1, G2 and G3 respectively. Transurethral resection of the bladder tumor was performed on all the patients and all the patients received routine post-operative intravesical instillation. A telephone interview follow-up was conducted on all the patients, and the average follow-up period was 36 months. EORTC risk tables were used to calculate risk scores for recurrence and progression for each patient. The recurrence and progression rates of different risk groups were recorded and compared with the estimated rates by EORTC risk table. Statistical analysis was used for comparison. ResultsTotal 1-year recurrence rate and progression rate for these patients were 25.9% and 3.8% respectively. According to calculated values of the patients, the 1-year recurrence rates of Group 0, Group 1-4, Group 5-9, Group 10-17 were 10.4%(5/48), 21. 5%(14/65), 35. 2% (19/54), 55.6%(10/18), respectively. The 1-year progression rates of Group 0, Group 2-6, Group 7-13, Group 14-23 were 0% (0/43), 1.5% (1/67), 6. 7% (4/60), 13. 3% (2/15). There was no significant difference between the real rates and estimated rates of the EORTC risk tables (P＞0. 05). However,the 1-year recurrence and progression rates between the low risk group, the medium risk group and the high risk group showed significant differences respectively (P ＜ 0. 05 ). Conclusions The EORTC risk tables are feasible to evaluate the recurrence and progression risk of non-muscle invasive bladder cancer in the present cohort. Nevertheless, the long term value and feasibility need more research to confirm.
RESUMEN
Objective To Validate the prognostic significance of the European Organization for Research and Treatment of Cancer (EORTC) risk tables in Chinese patients with non-muscle invasive bladder cancer (NMIBC). Methods According to the scoring standard of the EORTC system, 225 NMIBC patients were reviewed and divided into 3 groups: low, intermediate and high risk groups for recurrence and progression respectively. The probabilities of recurrence and progression at 1 year and 5 year for each group were calculated using life-table analysis and then compared with the EORTC risk tables. Log-Rank test and multivariable analysis were used to analyze the possible differences between risk groups and to find independent prognostic factors. Results For low (n= 32, 25), intermediate (n=109, 128) and high (n=84, 72) risk groups, the probabilities of recurrence and progression at 1 year were 15. 1%, 31.2%, 55.5% and 0. 3%, 2. 0%, 15.5% respectively. The probabilities at 5 year were 28. 2%, 55.2%, 75.0% and 1.4%, 12.9%, 54. 7%. All the results were similar to that of EORTC tables except the probability of progression at 5 year for the high progression risk group.The differences between different risk groups were significant (P＜0.01). In a multivariable analysis for recurrence and progression, the EORTC scores had independent significance (P＜0.01). Conclusions EORTC risk tables could stratify NMIBC patients effectively according to the risk of recurrence and progression. It could be a useful tool for Chinese urologists.
