Filter by:Low-dose computed tomography (LDCT) lung cancer (LC) screening can reduce mortality among heavy smokers, but there is a critical need to better identify people at higher risk and to reduce harms related to management of benign nodules. The most promising strategy is to combine novel tools to optimize clinical decisions and increase the benefit of screening. In this respect, the investigators already demonstrated that the combination of baseline LDCT features with a minimal invasive microRNA blood test was able to more precisely estimate the individual risk of developing LC. The investigators posit that additional immune-related and radiologic features can be integrated with the help of artificial intelligence (AI) to further implement LDCT screening strategies. The project will answer whether the combination of (bio)markers of different origin can predict LC development at baseline and over time, indicate which screen-detected lung nodules are likely to be malignant and ultimately reduce LC and all cause mortality.
This study is designed as a randomized, double-blind, sham-controlled, single-center research study in which healthy adults will be randomized 1:1 into one of two experimental groups, to receive transcutaneous auricular vagus nerve stimulation (taVNS) targeting either the auricular branch of the vagus nerve (ABVN) or tAN, which targets the ABVN and the auriculotemporal nerve (ATN): 1. Group 1: Sham taVNS followed by active taVNS 2. Group 2: Sham tAN followed by active tAN Participants will receive 30 minutes of sham stimulation (taVNS or tAN), followed by active stimulation (taVNS or tAN). Blood biomarkers (local and systemic) will be measured before and at several timepoints after stimulation to measure the molecular and cellular effects of the device.
The present multi-disciplinary study will assess blood biomarkers to investigate putative mechanisms of action of ECT. Laboratory findings will be correlated to clinical parameters, cognitive measures and psychometric outcome measures. The aim is to elucidate the underlying mechanisms for both treatment effects and cognitive side effects of ECT.
Nanoparticles (NPs) are minute pieces of material to which we are exposed every day in the air we breathe. Some are naturally occurring and have no impact on health, whereas others are produced from urban air pollution and can worsen diseases, particularly in the lungs and blood vessels. However, there is great interest in developing new NPs because of their unique properties that are useful for many applications, such as engineering, electronics and for drug delivery. At present it is unclear exactly what effects inhaled NPs have. Our current programme of research is designed to assess whether a specialized group of fats made in the body (called eicosanoids) drive the cardiovascular effects of NPs. The changes in the profiles of these fats will provide unique fingerprints that could be used to predict the actions of new NPs. In the proposed clinical study we shall investigate the effects of both environmental and manufactured carbonaceous NPs on the lungs, blood vessels, blood clotting, and levels of eicosanoids in blood and urine. We have previously investigated the cardiovascular effects of carbon nanoparticles after inhalation in man, and these experiments will investigate how the shape, size and composition of carbon particles influence these responses. These experiments will provide new insight into how NPs affect the body and pave the way for new ways to predict the toxic effects of NPs (reducing the need for animal experiments). The findings will enable the design of novel NP without the harmful characteristics of those found in air pollution.
EndoSearch aims to analytically validate a cluster of specific biomarkers for endometriosis diagnosis and disease recurrence. This signature will be tested on endometrium and blood from 975 patients, divided in two groups : 550 patients affected by endometriosis and 225 patients unaffected (controls). EndoSearch is not about drug or medical device assessment but a research study for biomarker analytical validation purpose.
