Idiopathic pneumonia syndrome (IPS) is a non-infectious pulmonary complication after hematopoietic cell transplantation (HCT) and is difficult to diagnose. We evaluated six candidate proteins in plasma samples at day 7 after HCT and at onset of IPS from 41 IPS cases to identify potential IPS diagnostic or prognostic biomarkers. Samples at similar times from 162 HCT recipients without documented infections and 37 HCT recipients with respiratory viral pneumonia served as controls. In multivariable models, a combination of Stimulation-2 (ST2, OR 2...

A woman in her 60s presented with 1 month of progressive dyspnea, watery rhinorrhea, and paroxysmal cough productive of clear, watery sputum. She was diagnosed with epidermal growth factor receptor (EGFR) mutation-positive lung adenocarcinoma at another institution 1 week prior to presentation and 3 weeks after the onset of symptoms. She was a never-smoker. She denied fevers and had completed a course of antibiotics for presumed pneumonia, without clinical improvement. She presented to the hospital due to increasing severity of her shortness of breath...

Emerging multidrug-resistant bacteria are a challenge for modern medicine, but how these pathogens are so successful is not fully understood. Robust antibacterial vaccines have prevented and reduced resistance suggesting a pivotal role for immunity in deterring antibiotic resistance. Here, we show the increased prevalence of Klebsiella pneumoniae lipopolysaccharide O2 serotype strains in all major drug resistance groups correlating with a paucity of anti-O2 antibodies in human B cell repertoires. We identify human monoclonal antibodies to O-antigens that are highly protective in mouse models of infection, even against heavily encapsulated strains...

Necrotising pneumonia (NP) is a rare but life-threatening complication of pulmonary infection. It is characterised by progressive necrosis of lung parenchyma with cavitating foci evident upon radiological investigation. This article reports the case of a 52-year-old woman, immunocompetent healthcare professional presenting to Accident and Emergency with NP and Staphylococcus aureus septicaemia. The cavitating lesion was not identified on initial chest X-ray leading to a delay in antimicrobial optimisation. However, the patient went on to achieve a full symptomatic recovery in 1 month and complete radiological recovery at 2-year follow-up...

Emergency medical services (EMS) personnel are an integral component of the healthcare framework and function to transport patients from various locations to and between care facilities. In addition to physical injury, EMS personnel are expected to be at high risk to acquire and transmit healthcare associated infections (HAIs) in the workplace. However, currently little is known about EMS biosafety risk factors and the epidemiological contribution of EMS to pathogen transmission within and outside of the healthcare sector...

BACKGROUND: Currently, contact precautions are recommended for patients colonized or infected with extended spectrum beta-lactamase producing enterobacteriaceae (ESBL-PE). Recent studies have challenged this strategy. This study aimed to assess the rate of ESBL-PE faecal carriage among hospitalized patients according to type of hospital ward, and to identify risk factors associated with carriage. METHODS: We conducted a point prevalence study in five different types of hospital wards (medical, surgical, intensive care unit (ICU), after care and rehabilitation and geriatric) in 8 French hospitals...

Tobacco exposure results in various changes to the airways and lung parenchyma. While emphysema represents the more common injury pattern, in some individuals, cigarette smoke injures alveolar epithelial and other lung cells resulting in diffuse infiltrates and parenchymal fibrosis. Smoking can trigger interstitial injury patterns mediated via recruitment and inappropriate persistence of myeloid and other immune cells including eosinophils. As our understanding of the role of cigarette smoke constituents in triggering lung injury continues to evolve, so does our recognition of the spectrum of smoking-related interstitial lung changes...

Streptococcus pneumoniae is a human pathobiont possessing a diverse array of multifunctional proteins essential for bacterial fitness and virulence. Gene expression is tightly controlled by regulatory components and among the pneumococcal sensorial tools, two‑component regulatory systems (TCS) are the most widespread and conserved. This review aims to provide a comprehensive analysis of original studies on pneumococcal TCS on a functional level. Despite a rather chaotic nomenclature, the current available information on pneumococcal regulation by these systems can be conveniently addressed, according to the regulation of pathophysiological cell processes and the responses to detectable environmental signals...

Few reports in the literature describe isolated peripheral neuropathies in relation to Mycoplasma pneumoniae infection without concurrent damage to the central nervous system. To our knowledge only a single case of mononeuritis multiplex with brachial plexus neuropathy coincident with M. pneumoniae has been documented until now. Here we present the first clinical case of lobar M. pneumoniae pneumonia in a 19-year-old female patient, where coincident neurological complications manifested as unilateral brachial plexus neuropathy, affecting axillar and suprascapular nerves...

OBJECTIVE: Complications adversely affect survival after lung cancer surgery. We tested the hypothesis that effects of complications after lung cancer surgery on survival vary substantially across the spectrum of postoperative complications. METHODS: The Society of Thoracic Surgeons General Thoracic Surgery Database was linked to Medicare data for lung cancer resections from 2002 through 2013. Linkage was achieved for 29,899 patients. A survival model was created that included operative complications as explanatory variables and adjusted for relevant baseline covariates...

BACKGROUND: Venovenous extracorporeal membrane oxygenation (VV-ECMO) is a valuable life support in acute respiratory distress syndrome (ARDS) in adult patients. However, the success of VV-ECMO is known to be influenced by the baseline settings of mechanical ventilation (MV) before its institution. This study was aimed at identifying the baseline ventilator parameters which were independently associated with hospital mortality in non-trauma patients receiving VV-ECMO for severe ARDS. METHODS: This retrospective study included 106 non-trauma patients (mean age: 53 years) who received VV-ECMO for ARDS in a single medical center from 2007 to 2016...

Instillation of intrapleural (IP) fibrinolytics has been used in patients with complicated parapneumonic pleural effusions to improve fluid drainage and decrease the need for surgical intervention. However, clinical trials have not included certain special populations such as pregnant females and there are currently no published case reports of this practice in this group. We describe the case of a 35-year-old female, G2P1 at 32 weeks of gestation, with a complicated pleural effusion due to influenza pneumonia with superimposed bacterial pneumonia...
