Determination of crystalline silica in respirable dust upon occupational exposure for Egyptian workers.

This study aims to investigate occupational exposure to crystalline silica dust at 22 factories in Egypt with different industrial activities like stone cutting, glass making, ceramic, and sand blasting. Dust samples were collected from work sites at the breathing zone using a personal sampling pump and a size-selective cyclone and analyzed using FTIR. The sampling period was 60-120 min. The results show that the exposure at each of the industrial sectors is very much higher than the current national and international limits, and that lead to a great risk of lung cancer and mortality to workers.

Lucas Rachael M. Rodney Harris If environmental exposures are shown to cause an adverse health outcome, reducing exposure should reduce the disease risk. Links between exposures and outcomes are typically based on ‘associations’ derived from observational studies, and causality may not be clear. Randomized controlled tr...

Authors: Sacco PC, Maione P, Palazzolo G, Gridelli C Abstract INTRODUCTION: Lung cancer is predominantly a disease that affects the elderly; about 30-40% of lung cancers are diagnosed in patients aged 70 or more. The increasing number of elderly patients over the next decades is generating a new social and health problem; despite that, these patients are under-represented in clinical trials and under-treated in clinical practice. Areas covered: The main difficulty in treating elderly patients is to maximize the therapy benefits while minimizing the treatment risk. Elderly patients show a vulnerable clinical profile...

Authors: Janker F, Weder W, Jang JH, Jungraithmayr W Abstract Lung cancer is the leading cause of cancer-related mortality worldwide. Animal models are key in analyzing cancer biology and therapy evaluation. We here compared relevant non-genetic lung cancer models with regard to tumor induction period, incidence, morbidity and mortality rate and the immunological composition of primary tumors and the occurrence of tertiary lymphoid organs (TLO): (I) intraperitoneal Urethane injection (1g/kg), (II) Lewis lung carcinoma (LLC) cell line model (intravenous or subcutaneous), and (III) ex vivo three-dimensional (3D) prim...

WSE has been related with high frequency of EGFR mutations and low frequency of KRAS mutations. The aim of this study was to evaluate large scale genomic alterations in lung adenocarcinomas associated with WSE using targeted next generation sequencing. Methods: DNA multi-targeted sequencing was performed in 42 fresh-froze...
