El uso de las mascarillas en la protección de las infecciones respiratorias: una revisión de revisiones

Introducción La emergencia sanitaria global causada por la actual pandemia de COVID-19 está suponiendo un enorme desafío a todos los niveles. El uso de la mascarilla puede reducir la propagación de la infección al minimizar la excreción de las gotitas de Flügge. Así, el objetivo de este trabajo es realizar una recopilación de la evidencia…

Influence of the Covid-19 pandemic on out-of-hospital cardiac arrest. A Spanish nationwide prospective cohort study

Aims: The influence of the COVID-19 pandemic on attendance to out-of-hospital cardiac arrest (OHCA) has only been described in city or regional settings. The impact of COVID-19 across an entire country with a high infection rate is yet to be explored. Methods: The study uses data from 8629 cases recorded in two time-series (2017/2018 and…

The effect of an online exercise programme on bone health in paediatric cancer survivors (iBoneFIT): study protocol of a multi-centre randomized controlled trial

Background New approaches on paediatric cancer treatment aim to maintain long-term health. As a result of radiotherapy, chemotherapy or surgery, paediatric cancer survivors tend to suffer from any chronic health condition. Endocrine dysfunction represents one of the most common issues and affects bone health. Exercise is key for bone mass accrual during growth, specifically plyometric…

Weight change in middle adulthood and risk of cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

Obesity is a risk factor for several major cancers. Associations of weight change in middle adulthood with cancer risk, however, are less clear. We examined the association of change in weight and body mass index (BMI) category during middle adulthood with 42 cancers, using multivariable Cox proportional hazards models in the European Prospective Investigation into…

Blood polyphenol concentrations and differentiated thyroid carcinoma in women from the European Prospective Investigation into Cancer and Nutrition (EPIC) study

Background Polyphenols are natural compounds with anticarcinogenic properties in cellular and animal models, but epidemiological evidence determining the associations of these compounds with thyroid cancer (TC) is lacking. Objectives The aim of this study was to evaluate the relations between blood concentrations of 36 polyphenols and TC risk in EPIC (the European Prospective Investigation into…

Adiposity and endometrial cancer risk in postmenopausal women: a sequential causal mediation analysis

Background Adiposity increases endometrial cancer (EC) risk, possibly through inflammation, hyperinsulinemia, and increasing estrogens. We aimed to quantify the mediating effects of adiponectin (anti-inflammatory adipocytokine); interleukin-6, interleukin-1-receptor antagonist, TNF-receptor-1 and -2, and C-reactive protein (inflammatory status biomarkers); C-peptide (hyperinsulinemia biomarker); free estradiol and estrone (estrogen biomarkers) in the adiposity-EC link in postmenopausal women. Methods We…
