P056 Occupational exposure to metals and risk of breast, chronic lymphocytic leukaemia, colorectal, prostate, and stomach cancer in the MCC-spain case control study
Arsenic, cadmium, chromium, and nickel are classified by IARC as human carcinogens (Group 1), while lead as a probable/possible carcinogen to humans (Group 2A). We explored associations between occupational exposure to metals and breast, chronic lymphocytic leukaemia (CLL), colorectal, prostate, and stomach cancer in the MCC-Spain population based case-control study. Methods The analyses were based on 3047 controls, and 1499 breast, 1539 colorectal, 332 CLL, 1070 prostate, and 382 stomach cancer cases. Occupational exposure to arsenic, cadmium, chromium, iron, lead and nickel was assessed using the MatEmEsp job-exposure matrix. Logistic regression models accounting for education, sex, geogr…
Efectividad del tratamiento antirretroviral combinado de gran actividad en eventos recurrentes de sida en una cohorte de seroconvertores al virus de la inmunodeficiencia humana
Resumen Introduccion La efectividad del tratamiento antirretroviral de gran actividad (TARGA) en la reduccion del tiempo al primer evento definitorio de sida ha sido demostrada por diversos estudios observacionales, pero el efecto en eventos recurrentes de sida no es tan evidente. Material y metodos Se dispone de 1.938 sujetos seroconvertores al VIH de la cohorte GEMES. Se ha utilizado una extension del modelo de Cox para analizar el tiempo desde la seroconversion a cada evento sida, que tiene en cuenta el tiempo entre sucesivos eventos y que permite que el riesgo de referencia cambie con el numero de paciente con sida previos. El calendario se dividio en tres periodos coincidiendo con la d…
Occupational Heat Exposure and Breast Cancer Risk in the MCC-Spain Study.
Background: Mechanisms linking occupational heat exposure with chronic diseases have been proposed. However, evidence on occupational heat exposure and cancer risk is limited. Methods: We evaluated occupational heat exposure and female breast cancer risk in a large Spanish case-control study. We enrolled 1,738 breast cancer cases and 1,910 frequency-matched population controls. A Spanish job exposure matrix, MatEmEsp, was used to assign estimates of the proportion of workers exposed (P greater than or equal to 25% for at least one year) and work time with heat stress (wet bulb globe temperature ISO 7243) for each occupation. We used three exposure indices: ever vs. never exposed, lifetime c…
