Multi-centre prospective study on lung cancer


Electronic nose technology using the Aeonose™ can play an important role in rapidly excluding lung cancer due to the high negative predictive value for various types of lung cancer. Next step will be to find out if the Aeonose™ can be used for population screening on lung cancer.

Abstract

The aim of this pilot study is to investigate the ability of an electronic nose (e-nose) to distinguish malignant gastric histology from healthy controls in exhaled breath. In a period of 3 weeks, all preoperative gastric carcinoma (GC) patients (n = 16) in the Beijing Oncology Hospital were asked to participate in the study. The control group (n = 28) consisted of family members screened by endoscopy and healthy volunteers. The e-nose consists of 3 sensors with which volatile organic compounds in the exhaled air react. Real-time analysis takes place within the e-nose, and binary data are exported and interpreted by an artificial neuronal network. This is a self-learning computational system. The inclusion rate of the study was 100%. Baseline characteristics differed significantly only for age: the average age of the patient group was 57 years and that of the healthy control group 37 years (P value = .000). Weight loss was the only significant different symptom (P value = .040). A total of 16 patients and 28 controls were included; 13 proved to be true positive and 20 proved to be true negative. The receiver operating characteristic curve showed a sensitivity of 81% and a specificity of 71%, with an accuracy of 75%. These results give a positive predictive value of 62% and a negative predictive value of 87%. This pilot study shows that the e-nose has the capability of diagnosing GC based on exhaled air, with promising predictive values for a screening purpose.

We’re Losing the Fight’: Tuberculosis Batters a Venezuela in Crisis

Article Aeonose project Venezuela

Tuberculosis (TB) is the world’s deadliest infectious disease, and a top ten cause of death worldwide. Each year, almost 2 million people die from TB. Venezuela is one of the high burden countries with devastating consequences. In Caracas, a medical team (PI: Dr. Jacobus de Waard, mentioned in the NYT-article) is conducting a study for fast TB-screening using an electronic nose (‘Aeonose’) for exhaled-breath analysis. Improved treatment regimes and diagnostics are urgently needed!
