ABSTRACTBackgroundThe association of dietary pattern with the risk of basal cell carcinoma (BCC) ... more ABSTRACTBackgroundThe association of dietary pattern with the risk of basal cell carcinoma (BCC) is little understood and has scarcely been investigated.ObjectivesWe assessed the association of several complete dietary patterns [Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and Pro-vegetarian dietary pattern] with the risk of BCC, conducting a nested case-control study (4 controls for each case).MethodsCases and controls were selected from the SUN (Seguimiento Universidad de Navarra) cohort using risk set sampling. Cases were identified among subjects free of skin cancer at baseline but who later reported a physician-made BCC diagnosis during the follow-up period. In the cohort we identified 101 incident cases of BCC.ResultsIn multivariable-adjusted conditional logistic regression analyses, better adherence to the Mediterranean diet (highest compared with lowest quintile) was associated with a 72% relative reduction in the odds of BCC (OR: 0.28; 95% CI: 0.10, 0.77; Ptrend = 0.014); the DASH diet was associated with a 68% RR reduction (OR: 0.32; 95% CI: 0.14, 0.76; Ptrend = 0.013) for the comparison between extreme quintiles. No association was found between a Pro-vegetarian dietary pattern and BCC. Higher fruit consumption (highest compared with lowest quintile, OR: 0.27; 95% CI: 0.11, 0.64;…

Por este motivo, buscamos estimar la seroprevalencia de anticuerpos frente a SARS-CoV-2 en personas que acuden a una consulta monográfica de ITS, comparar dicha seroprevalencia con la estimada en nuestra región y estudiar los factores asociados.Material y métodoEstudio observacional transversal que incluye a pacientes mayores de 18 años aún no vacunados atendidos en una consulta monográfica municipal de ITS para estudio o cribado, incluidos de forma consecutiva de marzo a abril de 2021. Se realizó test serológico rápido para SARS-CoV-2 y se recogieron variables demográficas, sociales y sexuales, diagnósticos de ITS y antecedentes de síntomas compatibles con infección por SARS-CoV-2.ResultadosSe incluyó a 512 pacientes, el 37% mujeres. Tuvieron alguna prueba positiva a SARS-CoV-2 124 pacientes (24,2%). Se relacionaron con un resultado positivo: el uso de mascarillas tipo FFP2 (OR 0,50) y el número de parejas sexuales superior a la mediana (OR 1,80). El uso de mascarillas FFP2 no se distribuyó de manera aleatoria en la muestra.ConclusionesLa población sexualmente activa ha tenido pruebas positivas a SARS-CoV-2 con más frecuencia que la población general. La principal vía de contagio en este grupo parece ser la vía respiratoria, por lo que la transmisión sexual es probablemente limitada y está relacionada con la proximidad que implican las relaciones sexuales.Background and objectiveSARS-CoV-2 is more easily spread by close contact, which is inherent to sexual intercourse. People with, or at risk for, sexually transmitted infections (STIs) may therefore have higher rates of COVID-19. The aim of this study was to estimate SARS-CoV-2 antibody seroprevalence in people seen at a dedicated STI clinic, compare our findings to the estimated seroprevalence in the local general population, and study factors associated with SARS-CoV-2 infection in this setting.Material and methodsCross-sectional observational study including consecutive patients older than 18 years of age who had not yet been vaccinated against COVID-19 and who underwent examination or screening at a dedicated municipal STI clinic in March and April 2021. We ordered rapid SARS-CoV-2 serology and collected information on demographic, social, and sexual variables, STI diagnoses, and history of symptoms compatible with SARS-CoV-2 infection.ResultsWe studied 512 patients (37% women). Fourteen (24.2%) had a positive SARS-CoV-2 test. Variables associated with positivity were use of FFP2 masks (odds ratio 0.50) and a higher-than-average number of sexual partners (odds ratio 1.80). Use of FFP2 masks was not randomly distributed in this sample.ConclusionsSexually active members of the population in this study had a higher incidence of SARS-CoV-2 infection than the general population. The main route of infection in this group appears to be respiratory, linked to close contact during sexual encounters; sexual transmission of the virus is probably limited.
