BACKGROUND Trainees are performing fewer bronchoscopies as a result of the increased use of endobronchial ultrasound-guided transbronchial needle aspiration. Workforce planning and changes in trainee working patterns may also have compounded this situation. We investigated current trends in endobronchial biopsy (EBB) and transbronchial biopsy (TBB) training and competency in respiratory trainee...
STUDY OBJECTIVE To study the diagnostic role of flexible bronchoscopy (FB) in immunocompromised patients with pulmonary infiltrates. DESIGN Prospective, observational study. SETTING Tertiary care hospital. PATIENTS A total of 104 consecutive non-HIV-infected immunocompromised patients with lung infiltrates in whom FB was performed. METHODS The primary outcome measure was the diagnostic ...
We have examined several emerging brominated flame retardants (BFRs) including 2-ethyl-1-hexyl-2,3,4,5-tetrabromobenzoate (TBB), bis(2-ethylhexyl) tetrabromophthalate (TBPH), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), 4,5,6,7-tetrabromo-1,1,3-trimethyl-3-(2,3,4,5-tetrabromophenyl)-indane (OBIND), and decabromodiphenyl ethane (DBDPE) in paired human maternal serum (n = 102) and breast milk (...
The Geostationary Lightning Mapper (GLM) on the Operational Environmental Satellite 16 (GOES-16) detects total lightning continuously, with a high spatial resolution and detection efficiency. Coincident data from GLM Advanced Baseline Imager (ABI) are used to explore correlation between cloud top properties flash activity across continental United States (CONUS) sector May September 2020. A lar...
There are no established opinions concerning whether the amount of tissue affects the accuracy of histological analyses in gastrointestinal stromal tumors (GISTs). The aim of the present study was to investigate the appropriate amount of tissue sample needed for mitotic count based on the risk classification of GISTs and the Ki-67 index using the following three methods: endoscopic ultrasound-g...
INTRODUCTION Rebiopsy in patients with advanced non-small-cell lung cancer (NSCLC) resistant to systemic chemotherapy may yield information on the mechanisms of resistance and planning of subsequent treatment. Transbronchial biopsy (TBB) using a flexible bronchoscope has been commonly used for establishing the initial diagnosis of lung cancer. The aim of this study was to assess the accuracy an...
OBJECTIVE Autoimmune hepatitis and primary sclerosing cholangitis are chronic inflammatory disorders of unknown aetiology, frequently associated with the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCAs) directed against an unknown antigen of myeloid cells. METHODS AND RESULTS Here, it is reported that p-ANCAs in autoimmune liver disorders react with beta-tubulin isotype...
Lung transplant (LT) recipients among solid organ transplant recipients are at high risk for cytomegalovirus (CMV) infections. We evaluated the effect of CMV-Immunoglobulins (CMV-IG) (Cytotect Biotest) on CMV pneumonia diagnosed in 303 follow-up transbronchial biopsies (TBB) of lung transplant recipients. 24 patients (control group, 155 TBB from 1999 to 2002) received acyclovir for 24 months an...
BACKGROUND Usual interstitial pneumonia (UIP) is a slowly progressive, usually fatal form of idiopathic interstitial pneumonia for which there is no effective treatment. Transbronchial biopsy (TBB) has been utilized only to exclude other diseases such as sarcoidosis, lymphangitic carcinoma, and infection, for example, but TBB is generally considered to have little role in confirming UIP. OBJE...
Many mammalian and avian predators consume the whole carcass of their small mammal prey. Thus, the contaminant load of the gut and its contents may be of toxicological significance, but pollutant loads in the gut of prey species are often not measured and their role in food-chain transfer of contaminants is largely unquantified. We investigated the importance of the gut and its contents in prey...
