BACKGROUND: The current literature is controversial regarding the importance of obese body mass index (BMI) classifications as a risk factor for pulmonary complications following outpatient surgery. The objective of the current investigation was to evaluate predictors of pulmonary outcomes following outpatient surgery and to assess the importance of BMI weight classifications in risk assessment. STUDY DESIGN: Patients with "outpatient" recorded as their inpatient/outpatient status in the 2012-2013 NSQIP database were included...

BACKGROUND: Legionella pneumophila (L. pneumophila) is a causative agent of severe pneumonia. It is highly adapted to intracellular replication and manipulates host cell functions like vesicle trafficking and mRNA translation to its own advantage. However, it is still unknown to what extent microRNAs (miRNAs) are involved in the Legionella-host cell interaction. METHODS: WT and MyD88-/- murine bone marrow-derived macrophages (BMM) were infected with L. pneumophila, the transcriptome was analyzed by high throughput qPCR array (microRNAs) and conventional qPCR (mRNAs), and mRNA-miRNA interaction was validated by luciferase assays with 3´-UTR mutations and western blot...

Clarithromycin is a broad-spectrum semi-synthetic macrolide indicated for treatment of pneumonias, Helicobacter pylori, and chlamydial and skin infections. The object of this study was to evaluate the pharmaceutical equivalence of 14 generic clarithromycin products marketed in Nairobi County, Kenya, to the innovator products, using in vitro dissolution profiles and similarity factors (f₂). Further, dissolution profiles of four innovator formulations manufactured in different sites were compared. Fourteen clarithromycin tablets/capsules and four suspensions were subjected to assay and comparative dissolution runs at pH 1...

BACKGROUND: We compared the performance of the modified Hodge test (MHT), Triton Hodge test (THT), Carba NP test (CNPt), simplified Carba NP test (CNPt-direct), blue-Carba NP test (BCT), and carbapenem inactivation method (CIM) for rapid and accurate carbapenemase detection. METHODS: The methods were evaluated by using 256 gram-negative isolates, including 197 Enterobacteriaceae (79 Enterobacter spp., 74 Klebsiella spp., 33 Escherichia coli, 10 Citrobacter spp., and 1 Serratia marcescens), 51 Acinetobacter baumannii, and 8 Pseudomonas aeruginosa strains...

Bacterial infections contribute to the disease progression of chronic obstructive pulmonary disease (COPD) by stimulating mucus production in the airways. This increased mucus production and other symptoms are often alleviated when patients are treated with mucolytics such as N-acetyl-L-cysteine (NAC). Moreover, NAC has been suggested to inhibit bacterial growth. Bacteria can release membrane vesicles in response to stress and recent studies report a role for these pro-inflammatory membrane vesicles (MVs) in the pathogenesis of airways disease...

Objective.: To evaluate the effect of rituximab (RTX) in patients with RA-related interstitial lung disease (RA-ILD) and identify factors associated with outcome after treatment. Methods.: An observational study of patients with RA-ILD was conducted from a cohort of RTX-treated RA patients in a single centre for >10 years. Progression was defined by any of the following: a decrease of pre-RTX forced vital capacity (FVC) >10% or diffusion capacity of carbon monoxide (DLCO) >15% predicted, worsening of the ILD score or death from progressive ILD...

Objectives: KPC-producing Klebsiella pneumoniae are an emerging public health problem around the globe. We defined the combinatorial pharmacodynamics and ability to suppress resistance of two 'old' antibiotics, fosfomycin and colistin, in time-kill experiments and hollow-fibre infection models (HFIM). Methods: Two KPC-2-producing K. pneumoniae isolates were used: one susceptible to both colistin and fosfomycin (KPC 9A: MIC colistin 0.25 mg/L and MIC fosfomycin ≤8 mg/L) and the other resistant to colistin and susceptible to fosfomycin (KPC 5A: MIC colistin 64 mg/L and MIC fosfomycin 32 mg/L)...

BACKGROUND: Clinically amyopathic dermatomyositis (CADM) is a distinct subgroup of dermatomyositis characterized by unique dermatologic manifestations without muscle involvement. CADM is frequently associated with interstitial lung disease (ILD), which usually has a rapidly progressive, fatal clinical course. Although CADM-related ILD (CADM-ILD) is well-described, data on the histopathology of CADM-ILD are limited. Organizing pneumonia and pulmonary vasculitis have rarely been reported...

Objective To assess the application of antibacterial agents, alongside pathogen prevalence and Pseudomonas aeruginosa drug resistance, with the aim of understanding the impact of inappropriate antibacterial use. Methods This retrospective study assessed bacteria from wounds, catheters, blood, faeces, urine and sputum of hospitalized patients in burn wards between 2007 and 2014. The intensity of use of antibacterial agents and resistance of P. aeruginosa to common anti-Gram-negative antibiotics were measured...

A 71-year-old man was admitted to our hospital for dyspnea, which had worsened over a period of more than six months. He was previously diagnosed as having cryptogenic organizing pneumonia, and was treated with steroids in another hospital. He had complained of worsening dyspnea, despite the treatment. We performed video-assisted thoracoscopic surgery because of the high level of lactate dehydrogenase and inconsistency of the usual interstitial pneumonia pattern. Pathologic specimens showed atypical lymphocytes confined to the pulmonary capillaries...

Cystic echinococcosis (CE) is an important helminthic zoonotic disease that commonly affects the liver and lungs. Imaging methods and serology establish the diagnosis in most cases. Chest x-ray can diagnose uncomplicated pulmonary hydatid cysts, whereas superinfection and/or rupture of the hydatid cyst (complicated cysts) may change the radiographic appearance and lead to delayed diagnosis and treatment. We report the case of a patient with hemoptysis and chest pain, where computer tomography scan of the lung suggested a large, ruptured hydatid cyst...

The Gram-positive anaerobic human pathogenic bacterium Atopobium vaginae causes most diagnosed cases of bacterial vaginosis as well as opportunistic infections in immunocompromised patients. In addition to its well-established role in carbohydrate metabolism, D-glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from Streptococcus pyogenes and S. pneumoniae have been reported to act as extracellular virulence factors during streptococcal infections. Here, we report the crystal structure of GAPDH from A. vaginae (AvGAPDH) at 2...

Bacterial meningitis has become a global concern, because of the emergence of antibiotic-resistant bacteria. It has been demonstrated that liposomes can enter bacteria, thus providing a possible treatment for numerous infections, including meningitis. Fusogenic liposomes are pH-sensitive with a high capacity to fuse with the bacteria membrane and promote intracellular drug release. Moreover, this ability can be improved by using cell-penetrating peptides (such as Tat47-57, which is a peptide derived from the Tat protein of HIV)...

In many respiratory diseases characterised by an intense inflammatory response, the balance between proteolytic enzymes (proteases, including elastases) and their inhibitors (proteinases inhibitors) is not neutral. In fact, an excess activity of neutrophil elastase (NE) and similar proteases has been reported to cause tissue damage and to alter the remodelling process in many clinical conditions such as pneumonia, respiratory distress and acute lung injury [ALI]. In recent years, several experimental NE inhibitors have been tested in preclinical and clinical studies of different conditions of inflammatory lung injury such as ALI and pneumonia, with contrasting results...
