Cytomegalovirus can cause severe disease with adverse outcome in immunocompromised patients. Severe cytomegalovirus infection in previously healthy individuals is rare. Here we present an unusual case of cytomegalovirus infection with neurological and pulmonary involvement in a previously healthy young woman with no history of immuno-suppression. Unfortunately, the disease followed a malignant course and despite the efforts of the medical staff the patient died. CMV infection should be considered in the diagnostic work-up of immunocompetent patients with fever and unexplained neurological or pulmonary manifestations...

Disease tolerance can preserve host homeostasis and limit the negative impact of infections. We report that vaccinated mice survived pulmonary challenge with the extremely virulent SchuS4 strain of F. tularensis, despite the persistence of large numbers (~104) of organisms. Transfer of 100 of these resident bacteria to naïve animals caused 100% lethality, demonstrating that virulence was maintained. Tissue damage in the lung was limited over the course of infection, and was associated with increased levels of amphiregulin...

Sin Nombre virus (SNV) causes hantavirus cardiopulmonary pulmonary syndrome (HCPS) with the loss of pulmonary vascular endothelial integrity, and pulmonary edema without causing cytopathic effects on the vascular endothelium. HCPS is associated primarily with a dysregulated immune response. We previously found occult signs of hemostatic imbalance in the form of a sharp >30-100 fold increase in the expression of plasminogen activator inhibitor type 1 (PAI-1), in serial blood plasma draws of terminal stage-patients...

Unilateral pulmonary vein atresia is a rare entity, usually congenital in origin. It is thought to result from failure of incorporation of common pulmonary vein to left atrium. Patients often present with recurrent chest infections and haemoptysis during infancy or early childhood. Associated anomalies are commonly present in these cases. Pulmonary angiography is generally used for definitive diagnosis; however, characteristic imaging findings on latest multislice CT can be virtually diagnostic.

Obese patients have increased rates of upper extremity injury, carpal tunnel syndrome, and upper extremity osteoarthritis. Preoperative considerations include cardiovascular disease, pulmonary disease, and diabetes mellitus. Intraoperative and anesthetic considerations include specialized equipment, patient positioning, and the physiology of obese patients. Postoperative considerations should include increased risk of cardiovascular complications as well as surgical site infections and malunion. Surgery of the hand and upper extremity may be less prone to the postoperative complications seen in other regions of the body...

BACKGROUND: Hantavirus pulmonary syndrome (HPS) is an infection endemic in Chile and Argentina, caused by Andes hantavirus (ANDV). The rodent Oligoryzomys longicaudatus is suggested as the main reservoir, although several other species of Sigmodontinae are known hosts of ANDV. Here, we explore potential ANDV transmission risk to humans in southern South America, based on eco-epidemiological associations among: six rodent host species, seropositive rodents, and human HPS cases. METHODS: We used ecological niche modeling and macroecological approaches to determine potential geographic distributions and assess environmental similarity among rodents and human HPS cases...

Protein lysine ubiquitination is a dynamic reversible post-translational modification that plays key roles in modulating different cellular processes. Porcine reproductive and respiratory syndrome virus (PRRSV) is a notorious pathogen, causing tremendous economic losses for the global swine industry. The possible involvement of ubiquitination in PRRSV infection is unclear. So anti-ubiquitination-based enrichment and LC-MS were performed to investigate the global ubiquitination events triggered by PRRSV infection in pulmonary alveolar macrophages...

Oxidative stress and endoplasmic reticulum (ER) stress are related states that can occur in cells as part of normal physiology but occur frequently in diseases involving inflammation. In this article, we review recent findings relating to the role of oxidative and ER stress in the pathophysiology of acute and chronic nonmalignant diseases of the lung, including infections, cystic fibrosis, idiopathic pulmonary fibrosis and asthma. We also explore the potential of drugs targeting oxidative and ER stress pathways to alleviate disease...

BACKGROUND: Non-conversion of sputum smear and culture prolongs the infectivity of the patient and has been associated with unfavorable outcomes. We aimed to evaluate factors associated with persistent sputum positivity at the end of two months of treatment of new case pulmonary tuberculosis (TB). METHODS: Data of 87 human immunodeficiency virus-negative patients with culture-positive drug-susceptible pulmonary TB admitted to local university hospital between September 2015 and September 2016 were reviewed...

We experienced a breakthrough fungal infection caused by Geotrichum capitatum during empirical therapy with caspofungin. A 68-year-old male patient with refractory acute lymphoblastic leukemia had received umbilical cord blood transplantation after two courses of induction therapy. Empirical therapy with caspofungin was initiated 5 days before transplantation. Tacrolimus was continuously infused to prevent graft-versus-host disease. A minidose of methotrexate was intravenously administered on days 1 and 3 post-transplantation, which was changed to prednisolone from day 7 due to severe mucositis...

Airborne fungal pathogens, predominantly Aspergillus fumigatus , can cause severe respiratory tract diseases. Here we show that in environments, fungal spores can already be decorated with nanoparticles. Using representative controlled nanoparticle models, we demonstrate that various nanoparticles, but not microparticles, rapidly and stably associate with spores, without specific functionalization. Nanoparticle-spore complex formation was enhanced by small nanoparticle size rather than by material, charge, or "stealth" modifications and was concentration-dependently reduced by the formation of environmental or physiological biomolecule coronas...

Previous studies indicated that single-nucleotide polymorphisms (SNPs) of genes coding for toll-like receptors (TLRs) and toll-interacting protein (TOLLIP) may be involved in the pathogenesis of pulmonary tuberculosis (PTB). This study was designed to investigate potential associations between the polymorphisms in TLR2, TLR4, and TOLLIP and susceptibility to latent tuberculosis infection (LTBI) or subsequent PTB in a Chinese Han population. A total of 209 PTB and 201 LTBI patients and 204 healthy control subjects (HCS) were enrolled in our study...

In a patient with a medical history of cancer, the most probable diagnosis of an 18 FDG-avid pulmonary mass combined with intracranial abnormalities on brain imaging is metastasized cancer. However, sometimes a differential diagnosis with an infectious cause such as aspergillosis can be very challenging as both cancer and infection are sometimes difficult to distinguish. Pulmonary aspergillosis can present as an infectious pseudotumour with clinical and imaging characteristics mimicking lung cancer. Even in the presence of cerebral lesions, radiological appearance of abscesses can look like brain metastasis...
