Introduction: In 2000 the College of Pulmonologists of General Hospitals undertook an epidemiological study (KBP-2000-CPHG) enrolling all new cases of histologically confirmed lung cancer managed in general hospitals. This paper reports the five year survival in these cases.
Methods: Vital status was available for 5447 out of 5667 patients included in the original study. The effect of different prognostic factors on mortality was assessed.
Results: At 5 years 567 patients (10.4%) were still alive. Median survival for the 4880 (89.6%) deceased patients was 7 months. Univariate analysis identified age, smoking history, performance status, histological type and disease stage (TMN classification) as determinants of survival. For non-small cell lung cancer (n=4885) multivariate analysis identified five predictive factors for mortality - age, gender histological type, performance status and stage.
Conclusions: Five year survival in lung cancer continues to be poor. As the risk factors for poor outcome at the time of diagnosis are not modifiable and pending the results of screening studies reduction in mortality must rest on primary prevention.

Idiopathic pulmonary fibrosis (IPF) is a fatal disease defined by a progressive decline in lung function due to scarring and accumulation of extracellular matrix (ECM) proteins. The SOCS (Suppressor Of Cytokine Signaling) domain is a 40 amino acid conserved domain known to form a functional ubiquitin ligase complex targeting the Von Hippel Lindau (VHL) protein for proteasomal degradation. Here we show that the SOCS conserved domain operates as a molecular tool, to disrupt collagen and fibronectin fibrils in the ECM associated with fibrotic lung myofibroblasts.

Using Fourier Transform Infrared spectroscopy (FTIR), it is possible to show chemical composition of materials and / or profile chemical changes occurring in tissues, cells, and body fluids during onset and progression of diseases. For diagnostic application, the use of blood would be the most appropriate in biospectroscopy studies since, (i) it is easily accessible and, (ii) enables frequent analyses of biochemical changes occurring in pathological states. At present, different studies have investigated potential of serum, plasma and sputum being alternative biofluids for lung cancer detection using FTIR.

The mechanism(s) underlying gut microbial metabolite (GMM) contribution towards alcohol-mediated cardiovascular disease (CVD) is unknown. Herein we observe elevation in circulating phenylacetylglutamine (PAGln), a known CVD-associated GMM, in individuals living with alcohol use disorder. In a male murine binge-on-chronic alcohol model, we confirm gut microbial reorganization, elevation in PAGln levels, and the presence of cardiovascular pathophysiology.
