BACKGROUND: The prevalence of hypothyroidism is high in hemodialysis (HD) patients and hypothyroidism increases all-cause mortality in HD patients. Comorbidities are common in HD patients and are associated with both mortality and hypothyroidism. The aim of the study is to explore the effect of the interactions of comorbidities and hypothyroidism on all-cause mortality in HD patients. METHOD: Patients with hypothyroidism (ICD-9-CM 244.0, 244.1, and 244.9) and matched patients without hypothyroidism in the Registry for Catastrophic Illness Patient Database of Taiwan Health Insurance from 2000 to 2010 were analyzed...

Chronic obstructive pulmonary disease (COPD) is associated with an increased risk for lung cancer and an aberrant microbiota of the lung. Microbial colonization contributes to chronic neutrophilic inflammation in COPD. Nontypeable Haemophilus influenzae (NTHi) is frequently found in lungs of stable COPD patients and is the major pathogen triggering exacerbations. The epithelial cytokine interleukin-17C (IL-17C) promotes the recruitment of neutrophils into inflamed tissues. The purpose of this study was to investigate the function of IL-17C in the pulmonary tumor microenvironment...

Primary bronchopulmonary mucoepidermoid carcinoma (BPMEC) is a rare tumor. The fusion protein MECT1-MAML2 has been implicated as a causative genetic event in salivary and BPMECs. Several studies have shown the impact of MECT1-MAML2 on the diagnosis and prognosis of salivary gland mucoepidermoid carcinoma; however, few studies have been published regarding MECT1-MAML2 in the context of primary BPMEC. We describe the clinicopathologic, genetic, and outcome data of 16 patients with BPMEC. Clinicopathologic features were recorded from the electronic medical records...

We present an interesting case where a patient is presented with a droopy left eyelid (as part of Horner syndrome) and Cushingoid features which were a result of a Pancoast tumour (apical lung tumour in superior pulmonary sulcus) involving the left lung. This tumour was secreting ectopic adrenocorticotropic hormone (ACTH), a paraneoplastic endocrine phenomenon, which resulted in Cushing syndrome symptomatology. Though most ectopic ACTH-producing lung cancers are either small cell or carcinoid tumours, this was in fact a large cell neuroendocrine cancer (LCNEC)...

Autoimmune disorders are distinct with over production and accumulation of free radicals due to its undisclosed genesis. The cause of numerous disorders as cancer, arthritis, psoriasis, diabetes, alzheimer's, cardiovascular disease, Parkinson's, respiratory distress syndrome, colitis, crohn's, pulmonary fibrosis, obesity and ageing have been associated with immune dysfunction and oxidative stress. In an oxidative stress, reactive oxygen species generally provoke the series of oxidation at cellular level. The buildup of free radicals in turn triggers various inflammatory cells causing release of various inflammatory interleukins, cytokines, chemokines, and tumor necrosis factors which mediate signal transduction and transcription pathways as nuclear factor- kappa B (NF-κB), signal transducer and activator of transcription 3 (STAT3), hypoxia-inducible factor-1 (HIF-1α) and nuclear factor-erythroid 2-related factor (Nrf2)...

The lungs are frequently affected by cancer metastasis. Although NRAS mutations have been associated with metastatic potential, their exact role in lung homing is incompletely understood. We cross-examined the genotype of various tumor cells with their ability for automatic pulmonary dissemination, modulated NRAS expression using RNA interference and NRAS overexpression, identified NRAS signaling partners by microarray, and validated them using Cxcr1- and Cxcr2-deficient mice. Mouse models of spontaneous lung metastasis revealed that mutant or overexpressed NRAS promotes lung colonization by regulating interleukin-8-related chemokine expression, thereby initiating interactions between tumor cells, the pulmonary vasculature, and myeloid cells...

BACKGROUND AND PURPOSE: Adenoid cystic carcinoma (ACC) of salivary glands is characterized by long-term distant metastasis, most commonly in lungs. No agreement has been reached about the role of surgical treatment of pulmonary lesions. We evaluated the long-term results of lung metastasectomy for ACC in order to identify factors that should be taken into account in selecting patients eligible for surgery and treatment planning. PATIENTS AND METHODS: A retrospective study was conducted on 109 patients selected from our institutional experience and from the International Registry of Lung Metastases...

BACKGROUND: Lung cancer is the leading cause of cancer-related morbidity and mortality worldwide. Patients with chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD), are exposed to a higher risk of developing lung cancer. Chronic inflammation may play an important role in the lung carcinogenesis among those patients. The present study aimed at identifying candidate biomarker predicting lung cancer risk among patients with chronic respiratory diseases. METHODS: We applied clinical bioinformatics tools to analyze different gene profile datasets with a special focus on screening the potential biomarker during chronic inflammation-lung cancer transition...

National and sub-national mortality, years of life lost due to premature mortality (YLLs), years lived with disability (YLDs) and disability-adjusted life years (DALYs) for household air pollution from solid cookfuel use (HAP) in Iran, 1990-2013 were estimated based on the Global Burden of Disease Study 2013 (GBD 2013). The burden of disease attributable to HAP was quantified by the comparative risk assessment method using four inputs: (1) exposure to HAP, (2) the theoretical minimum risk exposure level (TMREL), (3) exposure-response relationships of related causes (4) disease burden of related causes...

Non-small cell lung cancer (NSCLC) is the most prevalent type of lung cancer. The abnormal expression of many long non-coding RNAs (lncRNAs) has been reported involved in the progression of various tumours, which can be used as diagnostic indicators or antitumour targets. Here, we found that the long non-coding RNA 00312 was down-regulated in paired NSCLC tissues and correlated with poor clinical outcome; decreased linc00312 expression in NSCLC was associated with larger and later stage tumours. Functional experiments showed that linc00312 could inhibit cell proliferation and promote apoptosis in vitro and in vivo...

Atmospheric fine particulate matter 2.5 (PM 2.5) may carry many toxic substances on its surface and this may pose a public health threat. Epidemiological research indicates that cumulative ambient PM2.5 is correlated to morbidity and mortality due to pulmonary and cardiovascular diseases and cancer. Mitigating the toxic effects of PM2.5 is therefore highly desired. Bufei Huoxue (BFHX) capsules have been used in China to treat pulmonary heart disease (cor pulmonale). Thus, we assessed the effects of BFHX capsules on PM2...

BACKGROUND There is currently no reliable method to predict major postoperative cardiopulmonary complications for patients with non-small cell lung cancer (NSCLC). In this study, we hypothesized that exercise oxygen desaturation (EOD) and heart rate change results in a stair-climbing test (SCT) would predict postoperative cardiopulmonary complications for patients with NSCLC. MATERIAL AND METHODS We examined 171 patients (41 females and 130 males) with NSCLC by preoperative SCT from January 2010 to July 2015...

Metastasis impedes the successful chemotherapy for breast cancer. In this study, an Akt inhibitor (quercetin, Qu) was co-delivered with a chemotherapeutic agent (docetaxel, DTX) by using hyaluronic acid (HA)-modified nanoparticles (NPs) as vectors to block metastasis. Dual DTX/Qu-loaded HA/polylactic-co-glycolic acid-polyethyleneimine NPs (PP-HA/NPs) were prepared through a modified emulsion solvent evaporation technique. The particle size of PP-HA/NPs with narrow polydispersity was 209.8±10.8nm. Wound healing assay revealed that Qu co-delivery and HA modification elicited synergistic inhibitory effects on cell motility...

Titanium dioxide (TiO₂) has attracted wide attention as a potential photosensitizer (PS) in photodynamic therapy (PDT). However, bare TiO₂ can only be excited by ultraviolet illumination, and it lacks specific targeting ligands, which largely impede its application. In our study, we produced nitrogen-doped TiO₂ and linked it with an effective cancer cell targeting agent, folic acid (FA), to obtain N-TiO₂-FA nanoconjugates. Characterization of N-TiO₂-FA included Zeta potential, absorption spectra and thermogravimetric analysis...

BACKGROUND: There are few studies that have determined clinical outcomes following inferior vena cava filter (IVCF) insertion in cancer patients hospitalized for acute deep-vein-thrombosis (DVT) or pulmonary embolism (PE). METHODS AND RESULTS: We analyzed hospital discharge records of all patients with active cancer who were admitted to a California hospital specifically for acute DVT or PE between 2005 through 2009. Propensity and competing risk methodology were used to determine if IVCF-use lowered either 30-day mortality or the risk of recurrent PE, DVT, and major bleeding within 180days...

Low-dose computed tomography (LDCT) screening trials have based their risk selection algorithm on age and tobacco exposure, but never on pulmonary risk-related biomarkers. In the present study, the baseline inflammatory status, measured by C-reactive protein (CRP) level, and lung function, measured by forced expiratory volume in 1 s (FEV1), were tested as independent predictors of all-cause mortality in LDCT-screening participants. Between 2000 and 2010, 4413 volunteers were enrolled in two LDCT-screening trials, with evaluable baseline CRP and FEV1 values: 2037 were included in the discovery set and 2376 were included in the validation set...

Calcium (Ca2+) is a key player in the regulation of many cell functions. Just like Ca2+, mitochondria are ubiquitous, versatile, and dynamic players in determining both cell survival and death decisions. Given their ubiquitous nature, the regulation of both is deeply intertwined, whereby Ca2+ regulates mitochondrial functions, while mitochondria shape Ca2+ dynamics. Deregulation of either Ca2+ or mitochondrial signaling leads to abnormal function, cell damage or even cell death, thereby contributing to muscle dysfunction or cardiac pathologies...

The number of patients diagnosed with pulmonary nodules increased as more patients with high risk of lung cancer choose low-dose computed tomography (CT) scans for the screening of cancer. Clinicians might get two questions from the patients: what is the definite diagnosis of the nodule? What should we do? We have already got many guidelines trying to solve these problems. There are also several prediction models for pulmonary nodules. However, guidelines are not suitable for all types of patients, and the reality of patients is more complicated...
