Influencia del código postal en las hospitalizaciones pediátricas en Sevilla

Introducción El lugar de vivienda es un indicador del nivel socioeconómico que influye en la morbimortalidad y utilización de recursos sanitarios. Los objetivos de este estudio fueron analizar este efecto en las hospitalizaciones pediátricas y describir las tasas de hospitalización de los diagnósticos principales más frecuentes en la ciudad de Sevilla. Material y métodos Estudio…

El error diagnóstico en atención primaria

El primer gran estudio sobre seguridad del paciente, publicado hace 25 años1, ya señalaba que los eventos adversos debidos a error diagnóstico duplicaban los causados por fármacos. Ha tenido que transcurrir ese tiempo para que el error diagnóstico deje de ser un «elefante invisible» en la habitación de la seguridad, tras la consideración de área…

Helicobacter pylori infection, chronic corpus atrophic gastritis and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort: a nested case-control study

The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori…

Activity and determinants of cholinesterases and paraoxonase-1 in blood of workers exposed to non-cholinesterase inhibiting pesticides

Pesticide exposure has been associated with different adverse health effects which may be modulated to some extent by paraoxonase-1 (PON1) activity and genetic polymorphisms. This study assessed seasonal variations in PON1 activity (using paraoxon –POase–, phenylacetate –AREase–, diazoxon –DZOase– and dihydrocoumarin –DHCase– as substrates), erythrocyte acetylcholinesterase (AChE) and plasma cholinesterase (using butyrylthiocholine –BuChE– and benzoylcholine…

Dietary Flavonoid Intake and Colorectal Cancer Risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) Cohort

Flavonoids have been shown to inhibit colon cancer cell proliferation in vitro and protect against colorectal carcinogenesis in animal models. However, epidemiological evidence on the potential role of flavonoid intake in colorectal cancer (CRC) development is still sparse and inconsistent. We evaluated the association between dietary intakes of total flavonoids and their subclasses and risk…

Contribution of Persistent Organic Pollutant Exposure to the Adipose Tissue Oxidative Microenvironment in an Adult Cohort: A Multipollutant Approach

Despite growing in vitro and in vivo evidence of the putative role of persistent organic pollutants (POPs) in the induction of oxidative damage in cell structures, this issue has been poorly addressed from an epidemiologic perspective. The aim of this study was to explore associations between adipose tissue POP concentrations and the in situ oxidative…

Endometrial cancer risk prediction including serum-based biomarkers: Results from the EPIC cohort

Endometrial cancer risk prediction models including lifestyle, anthropometric, and reproductive factors have limited discrimination. Adding biomarker data to these models may improve predictive capacity; to our knowledge, this has not been investigated for endometrial cancer. Using a nested case-control study within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, we investigated the improvement…
