Flavouring found in e-cigarettes linked to 'popcorn lung'

ConclusionThis study shows three chemicals reportedly linked to serious lung damage are present in many flavoured e-cigarettes in the US, raising concerns about their safety. Although the study tested US brands, it's likely similar findings would be found here in the UK, where e-cigarettes are similarly unregulated.However, this issue is not black and white. The researchers' concerns have been rightly raised, and their conclusion that urgent research needs to follow this study seems logical given the apparent lack of knowledge in this area.  Still, much of the potential health risk and alarm factor of this study hangs on the strength of previous reports suggesting these chemicals can cause lung damage. But this particular study didn't address this directly. We don't yet know whether these chemicals, in their vaporised forms and inhaled at the levels typical in e-cigarettes, cause any lung damage.This study simply looked at how often the three chemicals were detected in e-cigarettes, assuming a link with potential lung damage from other studies that were not appraised here. What we really need is more information on the potential causal link between these chemicals and lung disease, particularly the doses at which any damage might occur, which may or may not be present in e-cigs. Many e-cigarette users may be asking themselves whether they should stop vaping. This study only provides indirect evidence of a risk linking chemicals in e-cigarettes to lung disease, ...

Authors: Harada K, Yasuda M, Hasegawa K, Yamazaki Y, Sasano H, Otsuka F Abstract Adrenocortical carcinoma (ACC) is a rare malignancy arising from adrenocortical parenchymal cells. Myxoid ACC is one of the newly identified, rare, but important histological variants of ACC, characterized by the presence of abundant extracellular Alcian Blue-positive myxoid material. Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant cancer predisposition syndrome, and the incidence of ACC in MEN1 patients has been reported to be between 1.4% and 6%. Here, we report the case of a 68-year-old Japanese woman harboring t...

This study aimed to investigate if hyperinsulinemia and/or insulin resistance was correlated with the occurrence of papillary thyroid cancer (PTC) in a group of Chinese patients. 258 inpatients were included in the study. According to the postoperative pathology results, all subjects were divided into PTC (n = 153) and control groups (with benign thyroid nodules, n = 105). Body mass index (BMI), fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), thyroid-stimulating hormone (TSH), FT4, FT3, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), serum uric acid (UA), ...

Authors: Procaccio L, Bergamo F, Manai C, Di Antonio V, Fassan M, Zagonel V, Lonardi S, Loupakis F Abstract Introduction: Lung metastases occur in 10-20% of patients with colorectal cancer (CRC). Most of them are treated with palliative intent and have a poor prognosis. Pulmonary metastasectomy may be a curative option for carefully selected patients with 5-year survival rates ranging from 25% to 60%. However, up to 70% of patients develop recurrence after pulmonary metastasectomy. Therefore, the identification of prognostic factors is essential in CRC patients with resectable lung metastases. Areas covered: This r...

Authors: Snijder J, Peraza J, Padilla M, Capaccione K, Salvatore MM Abstract Introduction: Idiopathic pulmonary fibrosis (IPF) is a relentless form of fibrotic lung disease with a median survival of approximately 3 years after diagnosis and a mortality rate that surpasses that of many types of cancer. The pathophysiology of IPF is complex as there are likely different stages of disease occurring simultaneously in the lung. Areas covered: Some scientists consider IPF as primarily an epithelial driven disease in which dysfunctional surfactant-producing cells take an etiological precedent. Others focus on the augmente...

This study involved patients from the North-East Indian population, where the numbers of reported cases are increasing rapidly and alarmingly. Oxidative stress, based on 8-OH-dG levels, was found to be significantly higher in gallbladder anomalies (cholelithiasis [CL] and cholecystitis [CS]) and GBC at the plasma and DNA level, and was associated with GBC severity. The expressions of key BER pathway genes were downregulated in gallbladder anomalies and GBC compared to controls, and in GBC compared to both non-neoplastic controls and gallbladder anomalies. Expression of XRCC1 and hOGG1 was significantly associated with both...

Activation of Ras-ERK1/2 has been testified to be linked to the progression of diverse cancers. Nonetheless, whether Ras-ERK1/2-tumorigenic pathway is mediated by epigenetic factors remains indistinct. The purpose of the research attempted to disclose the functions of H2BK5ac in Ras-ERK1/2-evoked CRC cell phenotypes.Materials and methodsWestern blot assay was implemented for exp...
