Interaction of sedentary behaviour and educational level in breast cancer risk.

OBJECTIVE: This cross-sectional study aims to analyse the relationship between sedentary behaviour and breast cancer (BC) risk from a social perspective. METHODS: Women aged 45-70 who participated in the Valencia Region Breast Cancer Screening Programme (2018-2019) were included, with a total of 121,359 women analysed, including 506 with cancer and 120,853 without cancer. The response variable was BC (screen-detected) and the main explanatory variable was sedentary behaviour (≤2 / >2-≤3 / >3-≤5 / >5 hours/day, h/d). Nested logistic regression models (M) were estimated: M1: sedentary behaviour adjusted for age and family history of BC; M2: M1 + hormonal/reproductive variables (menopausal status, number of pregnancies, hormone replacement therapy; in addition, months of breastfeeding was added for a subsample of women with one or more live births); M3: M2 + lifestyle variables (body mass index, smoking habits); M4: M3 + socioeconomic variables (educational level, occupation); Final model: M4 + gender variables (childcare responsibilities, family size). Interaction between sedentary behaviour and educational level was analysed in the Final model. Moreover, for the whole sample, postmenopausal women and HR+ BC, the Final model was stratified by educational level. RESULTS: Sedentary behaviour was associated with an increased risk of BC with a nearly statistically significant effect in the Final model (>2-≤3 h/d: OR = 1.22 (0.93-1.61); >3-≤5 h/d: OR = 1.14 (0.86-1.52); >5: OR = 1.19 (0.89-1.60)). For women with a low educational level, sitting more than 2 h/d was associated with an increased risk of BC in the whole sample (>2-≤3 h/d OR = 1.93 (1.19-3.21); in postmenopausal women (>2-≤3 h/d, OR = 2.12 (1.18-2.96), >5h/d OR = 1.75 (1.01-3.11)) and in HR+ BC (>2-≤3h/d, OR = 2.15 (1.22-3.99)). Similar results were observed for women with one or more live births. Conclusions Sitting >2 h/d is associated with BC risk in women with low educational level, especially in postmenopausal women and those with live births.

[Results of 10 years of the Colorectal Cancer Prevention Program in the Valencian Community.] / Resultados de 10 años del Programa de Prevención de Cáncer Colorrectal en la Comunitat Valenciana.

OBJECTIVE: The population-based Program for the Prevention of Colorectal Cancer (PPCRC) was implemented in 2005 in the Valencian Community, following the guidelines of the European Union. To achieve the desired effectiveness in these programs, it is necessary to achieve a series of requirements, assessable through the program indicators. The objective of this study was to analyze the evolution of the program indicators from 2006 to 2016. METHODS: The accumulated indicators for the period were calculated. The Poisson regression model was used to compare the indicators by age groups and sex, by type of screening, by type of fecal occult blood test (FOBT) and by year. RESULTS: The number of people invited to participate was 1,934,266. The participation rate was 44.4%, being 87.6% in the subsequent screening and 33.7% in the initial one, with men over 60 having the lowest participation figures. Except for the positive predictive value (PPV) for low risk adenomas, which was higher in a group of men aged 50 to 59 years of successive screening, the detection rates and PPV for the different types of lesions were higher in the initial screening, with immunological test and in the group of men over 60 years old. Throughout the period, there was a decrease in the test positivity rates and in the advanced adenomas and cancers detection rates. CONCLUSIONS: The PPCCR reaches levels of quality for which the effectiveness of the program is demonstrated. However, the insufficient participation of some population groups highlights the need to carry out studies to achieve the desired objectives in all population groups and thus result in greater effectiveness of the program.

OBJETIVO: El Programa Poblacional de Preven-ción de Cáncer Colorrectal (PPCCR) se implantó en 2005 en la Comunitat Valenciana, siguiendo las directrices de la Unión Europea. Para alcanzar la efectividad deseada en estos programas es necesario conseguir una serie de requisitos, valorables mediante los indicadores del programa. El objetivo del presente estudio fue analizar la evolución de los indicadores del programa de 2006 a 2016. METODOS: Se calcularon los indicadores acumulados para el periodo. Se empleó el modelo de regresión de Poisson para comparar los indicadores por grupos de edad y sexo, por tipología de cribado, por tipo de test de sangre oculta en heces (TSOH) y por año. RESULTADOS: El número de personas invitadas a participar fue de 1.934.266. La tasa de participación fue del 44,4%, siendo del 87,6% en el cribado sucesivo y del 33,7% en el inicial, teniendo los hombres mayores de 60 años las menores cifras de participación. Excepto el valor predictivo positivo (VPP) para adenomas de bajo riesgo, que fue superior en grupo de hombres de 50 a 59 años en cribado sucesivo, las tasas de detección y VPP para los diferentes tipos de lesiones fueron mayores en el cribado inicial, con el tipo de test inmunológico y en el grupo de hombres mayores de 60 años. A lo largo del periodo se produjo un descenso en las tasas de positividad para el test y las tasas de detección de adenomas avanzados y cánceres. CONCLUSIONES: El PPCCR alcanza niveles de calidad para los que se demuestra la eficacia del programa. Sin embargo, la participación insuficiente de algunos grupos poblacionales remarca la necesidad de realizar estudios para conseguir los objetivos deseados en todos los grupos poblacionales y así redundar en una mayor eficacia del programa.

[Do women in the Valencian Community accept self-sampling as a form of cervical cancer screening?] / ¿Aceptan las mujeres de la Comunidad Valenciana la auto-toma como forma de cribado de cáncer de cérvix?

OBJECTIVE: The use of new devices such as the self-sampling for the determination of the Human Papilloma Virus (HPV), could facilitate the implementation of population screening programs and increase the participation of women. The objective of the study was to find out the women´s knowledge and attitudes towards cervical cancer screening as well as the acceptability of self-sampling. METHODS: Analytical cross-sectional study by telephone survey carried out on a random sample of 389 women from 35 to 65 years of age. The women were asked about their attitudes and knowledge of the screening and preference for HPV determination by self-sampling or by a healthcare professional. RESULTS: 86.9% of the women preferred self-sampling as a screening method and 93.3% had undergone a previous cervical cytology. 51.4% of the women had a high level of knowledge about cervical cancer screening. Younger women (POR 9.26; 95% CI 1.04-24.38), higher level of education (POR 4.6; 95% CI: 1.92-11.00), and higher level of knowledge (POR 2.78; 95% CI: 1.69-9.29), presented higher preferences for the determination of HPV by self-sampling. The trend in age, educational level and knowledge was the same for the prevalence of previous cervical cytology. CONCLUSIONS: The acceptance of self-testing as a method of cervical cancer screening is high among women. Efforts should be made to raise awareness among women to reduce possible inequalities in access and to encourage informed participation.

OBJETIVO: El uso de la auto-toma para determinación del Virus del Papiloma Humano (VPH), podría facilitar la implantación de los programas de cribado poblacional y aumentar la participación de las mujeres. El objetivo de estudio fue conocer los conocimientos y actitudes de las mujeres frente al cribado del cáncer de cérvix y la aceptación de la auto-toma como método de cribado para la detección del VPH. METODOS: Estudio transversal analítico mediante encuesta telefónica realizada a una muestra aleatoria de 389 mujeres entre 35 y 65 años de la Comunitat Valenciana. Se preguntó a las mujeres sobre prácticas preventivas previas, actitudes y conocimientos del cribado, y la preferencia por la determinación de VPH mediante auto-toma o por un profesional sanitario. RESULTADOS: El 86,9% de las mujeres encuestadas prefirieron la auto-toma como método de cribado y el 93,3% se habían realizado una citología cervical previa. El 51,4% de las mujeres tenían un nivel de conocimiento alto sobre el cribado del cáncer de cérvix. Las mujeres de menor edad (POR 9,26; IC95%1,04-24,38), mayor nivel de estudios (POR 4,6; IC95%:1,92-11,00), y mayor nivel de conocimientos (POR 2,78; IC95%:1,69-9,29), presentaron preferencias mayores por la determinación de VPH mediante auto-toma. La tendencia en la edad, nivel de estudios y conocimientos fue la misma para la prevalencia de realización de la citología cervical previa. CONCLUSIONES: La aceptación de la auto-toma como método de cribado del cáncer de cérvix es elevada entre las mujeres. Se deben dedicar esfuerzos para aumentar el conocimiento en las mujeres para reducir posibles desigualdades de acceso y fomentar una participación informada.

Prognostic factors of survival in HIV/HCV co-infected patients with hepatocellular carcinoma: The CARCINOVIC Cohort.

BACKGROUND & AIMS: HIV/HCV co-infected patients with hepatocellular carcinoma (HCC) have poorer survival than HCV mono-infected patients. We aimed to evaluate the prognostic factors for survival. METHODS: From 2006 to 2013, 55 incident HCCs among HIV+/HCV+ patients, from three ANRS cohorts, were compared with 181 HCCs in HIV-/HCV+ patients from the ANRS Cirvir cohort. RESULTS: HIV+/HCV+ patients were younger (50 years [IQR: 47-53] vs 62 [54-70], P < 0.001), male (89% vs 63%, P < 0.001) than HIV-/HCV+ patients. At HCC diagnosis, both groups had a majority of non-responders to anti-HCV-therapy, and HIV+/HCV+ patients had more frequently known a previous cirrhosis decompensation (31% vs 14%, P = 0.005). At diagnostic imaging, there were more infiltrative forms of HCC in HIV+/HCV+ group (24% vs 14%, P < 0.001), associated with tumour portal thrombosis in 29%. During a median follow-up period of 11.96 [5.51-27] months since HCC diagnosis, a majority of palliative treatments were decided in HIV+/HCV+ patients (51% vs 19%, P < 0.001). The 1 and 2-year crude survival rates were 61% versus 78% and 47% versus 63%, P = 0.003 respectively. In a Cox model multivariate analysis adjusted for the cohort, age and sex, the most important prognostic factor for survival was the infiltrative form of the tumour (aRR: 8.10 [4.17-15.75], P < 0.001). CONCLUSIONS: The radiological aggressiveness of the tumour is the best prognostic factor associated with poorer survival of HCC in HIV+/HCV+ patients. High α-foetoprotein level and decompensated cirrhosis are other ones. This justifies a particular attention to the detection and the management of small nodules in this high-risk population.

Impact of chagas disease in bolivian immigrants living in europe and the risk of stigmatization.

Background. The prevalence of Chagas disease in endemic countries varies with the kind of vector involved and the socioeconomic conditions of the population of origin. Due to recent immigration it is an emerging public health problem in Europe, especially in those countries which receive immigrant populations with a high prevalence of carriers. The study reviews the impact of the disease on Bolivian immigrants living in Europe, the preventive measures and regulations applied in European countries, and their repercussion on possible stigmatization of certain population groups. Methods. The Bolivian immigrant population resident in 2012 was estimated and the affected population in different European countries was calculated with data on carrier prevalence that were recently published. The preventive measures and regulations available in Europe were also reviewed. MEDLINE-PubMed, GoPubMed, and Embase were consulted for the literature review. Results. The Bolivian immigrant population has the highest prevalence of Chagas carriers (6.7%-25%) compared to the overall Latin American population (1.3%-2.4%). Only in Spain, France, Belgium, UK, Portugal, Italy, Switzerland, The Netherlands, and Germany, preventive measures are applied to this population. The established regulations are insufficient and completely different criteria are applied in the different countries and this could reflect a certain degree of stigmatization.
