BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and fatal disease. Histone deacetylase 6 (HDAC6) alters function and fate of various proteins via deacetylation of lysine residues, and is implicated in TGF-β1-induced EMT (epithelial-mesenchymal transition). However, the role of HDAC6 in pulmonary fibrosis is unknown. METHODS: HDAC6 expression in IPF and control lungs was assessed by quantitative real-time PCR (qRT-PCR) and immunoblots. Lung fibroblasts were treated with TGF-β1 ± HDAC6 inhibitors (Tubacin, Tubastatin, ACY1215, or MC1568), and fibrotic markers such as type I collagen were assessed using qRT-PCR and immunoblots...

RATIONALE: Cigarette smoking is associated with increased risk of acute respiratory distress syndrome (ARDS) in patients following severe trauma; however, mechanisms underlying this association are unknown. OBJECTIVES: To determine whether cigarette smoking contributes to ARDS development following trauma by altering community composition of the lung microbiota Methods: We studied lung microbiota of mechanically ventilated patients admitted to the intensive care unit (ICU) following severe blunt trauma using 16S rRNA gene amplicon sequencing of endotracheal aspirate (ETA) samples obtained upon ICU admission (n=74) and at 48 hours post-admission (n=30)...

BACKGROUND: Inflammatory myofibroblastic tumor (IMT) is a rare, distinctive lesion composed of a proliferation of myofibroblastic spindle cells accompanied by an inflammatory infiltrate. It was first described in the lung, but its occurrence at various extrapulmonary sites has also been reported. The literature mentions only a handful of cases of IMT in the breast and only 1 case in the male breast. We report the second case of IMT in the male breast. CASE REPORT: A 60-year-old male presented with a large, lobulated lump in the left breast that had progressively increased in size during the past year...

Background: FDG-avid thyroid incidentalomas (TI) are seen in approximately 2.5% of patients imaged for staging or response assessment of malignancy and represent thyroid cancer in approximately 35% of cases. Consequently, the 2015 ATA guidelines strongly recommend investigation of all FDG-avid nodules ≥1cm with US and fine needle aspiration cytology (FNA). This study aims to assess the overall and thyroid cancer specific survival in a large cohort of patients with FDG-avid TI with long-term follow-up to assess the validity of this approach...

Altered sphingolipid metabolism is associated with increased inflammation; however, the impact of inflammatory mediators, including neutrophil elastase (NE), on airway sphingolipid homeostasis remains unknown. Using a well-characterized mouse model of NE oropharyngeal aspiration, we investigated a potential link between NE-induced airway inflammation and increased synthesis of various classes of sphingolipids, including ceramide species. Sphingolipids in bronchoalveolar lavage fluids (BAL) were identified and quantified using reverse phase high-performance liquid chromatography/electrospray ionization tandem mass spectrometry analysis...

Transbronchial needle aspiration (TBNA) of small lesions or lymph nodes in the lung may result in nondiagnostic tissue samples. We demonstrate the integration of an optical coherence tomography (OCT) probe into a 19-gauge flexible needle for lung tissue aspiration. This probe allows simultaneous visualization and aspiration of the tissue. By eliminating the need for insertion and withdrawal of a separate imaging probe, this integrated design minimizes the risk of dislodging the needle from the lesion prior to aspiration and may facilitate more accurate placement of the needle...

Metastatic cancer represents the most common form of intraocular malignancy. Due to its abundant vascular supply the choroid is the most common ocular site for intraocular metastatic disease (approximately 90%). Less than 10% of intraocular metastases are located in the iris and/or ciliary body, whereas the retina and vitreous are rarely affected. Most intraocular metastases are carcinomas; the majority of metastases originate from breast cancer in females and lung cancer in males. However, virtually every primary malignancy has been described to metastasize to intraocular structures...

Inhibiting specific gene expression with short interfering RNA (siRNA) provides a new therapeutic strategy to tackle many diseases at the molecular level. Recent strategies called high-density lipoprotein (HDL)-mimicking peptide-phospholipid nanoscaffold (HPPS) nanoparticles have been used to induce siRNAs-targeted delivery to scavenger receptor class B type I receptor (SCARB1) expressing cancer cells with high efficiency. Here, eight ideal therapeutic target genes were identified for advanced lung cancer throughout the screenings using endobronchial ultrasonography-guided transbronchial needle aspiration (EBUS-TBNA) and the establishment of a personalized siRNA-nanoparticle therapy...

OBJECTIVE: Dendriform pulmonary ossification (DPO) is a rare lung disease in which mature bone is present in the peripheral interstitium of the lung. It typically occurs in patients with usual interstitial pneumonia (UIP). We assessed patients with CT findings of DPO without UIP to determine possible causative factors and to assess the clinical and CT course. We hypothesized that DPO without UIP would be a unique entity. MATERIALS AND METHODS: We retrospectively reviewed CT reports for the word "ossification...

Gene methylation has been frequently observed in lung cancer. However, the use of methylated genes in bronchial aspirates of patients with lung cancer remains to be evaluated. The purpose of this study was to analyze whether the detection of genes with aberrant promoter methylation can be useful noninvasive biomarkers in bronchial aspirates from lung cancer. We found that the methylation status of the cyclin-dependent kinase inhibitor 2A (P16), Ras association domain family 1 isoform (RASSF1A), adenomatous polyposis coli (APC) and short stature homeobox 2 (SHOX2) genes was significantly correlated with lung cancer in bronchial aspirates...

INTRODUCTION: It is crucial to diagnose the subtype of lung cancer quickly and accurately for effective therapy. Conventional cytology staining sometimes provides limited information, and additional tissue is often required to diagnose lung cancer. Cell blocks (CB) recovered during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) increases the diagnostic accuracy of the procedure and the likelihood of additional valuable histochemical and immunohistochemical staining...

Upper extremity deep vein thrombosis is an extremely important clinical entity with potential for considerable morbidity and mortality. A 64-year-old woman was brought to the emergency department with complaints of left upper limb and neck swelling for 4 days. Ultrasonography of the neck showed thrombosis of the left internal jugular and other surrounding veins associated with local lymphadenopathy. Computed tomography (CT) of the neck also showed a hypodense 0.6 cm × 0.8 cm × 1.2 cm lesion in the right middle lobe bronchus, causing complete occlusion and collapse of the right middle lobe of the lung...

In spite of their powerful anti-inflammatory effect, glucocorticoids have shown no significant clinical benefit in respiratory syncytial virus (RSV)-induced bronchiolitis, the reason for which remains unclear. Upon glucocorticoid binding, the cytoplasmic glucocorticoid receptor (GR) translocates to the nucleus with the help of importin-13 (IPO13). Here, we report that RSV infection reduced GR nuclear translocation in the nasopharyngeal aspirate (NPA) of the RSV-infected infants, lungs of infected mice, and A549 cells, which coincided with decreased IPO13 expression...

The great risks of swallowing are choking and aspiration of food into the lungs. Both are rare in normal functioning humans, which is remarkable given the diversity of foods and the estimated 10 million swallows performed in a lifetime. Nevertheless, it remains a major challenge to define the food properties that are necessary to ensure a safe swallow. Here, the mouth is viewed as a well-controlled processor where mechanical sensory assessment occurs throughout the occlusion-circulation cycle of mastication...
