OBJECTIVES: In the contemporary ICU, mechanically ventilated patients may not have arterial blood gas measurements available at relevant timepoints. Severity criteria often depend on arterial blood gas results. Retrospective studies suggest that nonlinear imputation of PaO2/FIO2 from SpO2/FIO2 is accurate, but this has not been established prospectively among mechanically ventilated ICU patients. The objective was to validate the superiority of nonlinear imputation of PaO2/FIO2 among mechanically ventilated patients and understand what factors influence the accuracy of imputation...

Background: Large cell neuroendocrine carcinoma of the lung (LCNEC) is a rare disease with poor prognosis and limited treatment options. Neuroendocrine tumors frequently show overactivation of the mTOR pathway. Based on the good activity of the mTOR inhibitor everolimus in different types of neuroendocrine tumors and the results of a previous phase I trial we evaluated the efficacy and safety of everolimus in combination with carboplatin and paclitaxel as upfront treatment for patients with advanced LCNEC...

BACKGROUND: CXCL12 (SDF1) is reported to promote cancer progression in several preclinical models and this is corroborated by the analysis of human tissue specimens. However, the relationship between CXCL12 expression and cancer survival has not been systematically assessed. METHODS: We conducted a systematic review and meta-analysis of studies that evaluated the association between CXCL12 expression and cancer survival. RESULTS: Thirty-eight studies inclusive of 5807 patients were included in the analysis of overall, recurrence-free or cancer-specific survival, the majority of which were retrospective...

BACKGROUND Lung adenocarcinoma (LUAD) is the most frequent lung cancer. MicroRNAs (miRNAs) are believed to have fundamental roles in tumorigenesis of LUAD. Although miRNAs are broadly recognized in LUAD, the role of microRNA-375 in LUAD is still not fully elucidated. MATERIAL AND METHODS We evaluated the significance of miR-375 expression in LUAD by using analysis of a public dataset from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database and a literature review. Furthermore, we investigated the biological function of miR-375 by gene ontology enrichment and target prediction analysis...

PURPOSE: Radiotherapy plays a major role in relieving pain caused by bone metastases; paradoxically initial flare of symptom is common. Our objectives were to assess prospectively the incidence, and to identify predictor's factors of this acute complication. PATIENT AND METHODS: Forty-one patients treated with analgesic external beam radiotherapy were followed prospectively. Patients recorded pain severity and analgesic intake was documented. Pain flare was defined as an increase of two points in the intensity of pain on the numerical scale with no reduction in analgesic intake and/or 25% increase of the analgesic intake without decreasing pain intensity...

BACKGROUND: Both adverse early life exposures and adult smoking can negatively influence adult lung function trajectory but few studies consider how the impact of early life exposures may be modified by subsequent smoking. METHODS: The Medical Research Council National Survey of Health and Development is a nationally representative cohort, initially of 5362 individuals, followed since enrolment at birth in March 1946. Using data collected prospectively across life and multilevel modelling we investigated how the relationships between early life exposures (infant lower respiratory infection, manual social class, home overcrowding and pollution exposure) and FEV1 and FVC trajectories between ages 43 and 60-64 were influenced by smoking behaviour...

Treatment of non-tuberculous mycobacterial lung disease (NTM-LD) is challenging for several reasons including the relative resistance of NTM to currently available drugs and the difficulty in tolerating prolonged treatment with multiple drugs. Yet-to-be-done, large, multicenter, prospective randomized studies to establish the best regimens will also be arduous because multiple NTM species are known to cause human lung disease, differences in virulence and response to treatment between different species and strains within a species will make randomization more difficult, the need to distinguish relapse from a new infection, and the difficulty in adhering to the prescribed treatment due to intolerance, toxicity, and/or drug-drug interactions, often necessitating modification of therapeutic regimens...

INTRODUCTION: We present a case-control study of non-AIDS-defining cancers (NADCs) in a cohort of HIV-infected patients where we value the incidence, survival and prognostic factors of mortality. METHODS: All NADCs diagnosis conducted from 2007 to 2011 in 7 hospitals were collected prospectively, with a subsequent follow up until December 2013. A control group of 221 HIV patients without a diagnosis of cancer was randomly selected. RESULTS: Two hundred and twenty-one NADCs were diagnosed in an initial cohort of 7,067 HIV-infected patients...

Technological advances in radiation therapy permit steep dose gradients from the target to spare normal tissue, but increase the risk of geographic miss. Suboptimal target delineation adversely affects clinical outcomes. Prospective peer review is a method for quality assurance of oncologists' radiotherapy plans. Published surveys suggest it is widely implemented. However, it may not be feasible to review every case before commencement of radiation therapy in all departments. The rate of plan changes following peer review of cases without a specific subsite or modality is typically around 10%...

A 76-year-old man underwent F-FDG PET/CT to complete staging and characterize a suspicious lung mass. Images showed intense uptake in the lung lesion and faint uptake in correspondence of a gastric mass, which was subsequently biopsied revealing a gastrointestinal stromal tumor. A F-FAZA PET/CT was also performed because of patient's enrollment in a prospective clinical trial (trial registration no. EudraCT 2011-002647-98), showing heterogeneous uptake of F-FAZA in the pulmonary lesion and faint uptake in correspondence of the gastrointestinal stromal tumor...
