Research suggests vapers are vulnerable to pneumonia

(European Lung Foundation) The vapor from e-cigarettes seems to help pneumonia-causing bacteria stick to the cells that line the airways, according to research published in the European Respiratory Journal.

Care of infectious diseases (prevention, diagnosis, and treatment) represents a large part of the activity of pediatric practices as well as primary care, emergency departments, and hospitals. The bacterial and viral species involved in pediatric community-acquired infections (CAIs) can induce severe, moderate, or mild diseases, which require care by hospitalization, emergency departments, or first-line clinicians. For example, pneumococcus manifests as a spectrum of diseases ranging from severe invasive diseases, such as meningitis, bacteremic pneumonia, and bacteremia, to less severe but more frequent diseases, such as a...

Conclusion:S. pneumoniae remains a pathogen causing considerable mortality. In adults, non-IPD should be considered of comparable importance as IPD. Increasing pneumococcal vaccine awareness at the healthcare professional and patient levels is essential for increasing vaccine uptake, thus decreasing the incidence, severity and sequelea of pneumococcal disease.

(University of California - San Diego) Using artificial intelligence and machine learning techniques, researchers at Shiley Eye Institute at UC San Diego Health and University of California San Diego School of Medicine, with colleagues in China, Germany and Texas, have developed a new computational tool to screen patients with common but blinding retinal diseases, potentially speeding diagnoses and treatment.

Purpose: Fibrotic interstitial lung diseases presenting with nonspecific and overlapping radiologic findings may be difficult to diagnose without surgical biopsy. We hypothesized that baseline quantifiable radiologic features and their short-term interval change may be predictive of underlying histologic diagnosis as well as long-term survival in idiopathic pulmonary fibrosis (IPF) presenting without honeycombing versus nonspecific interstitial pneumonia (NSIP). Materials and Methods: Forty biopsy-confirmed IPF and 20 biopsy-confirmed NSIP patients with available high-resolution chest computed tomography 4 to 24 month...

Platelet collagen receptor glycoprotein VI (GPVI) and podoplanin receptor C-type lectin-like receptor 2 (CLEC2) are receptors implicated in platelet activation that both signal via an immunoreceptor tyrosine–based activation motif. Platelets are necessary for host defense and prevention of hemorrhage during sepsis, but the role of platelet GPVI and CLEC2 herein is unknown. To investigate this, we infected mice depleted of platelet GPVI or CLEC2 by antibody treatment or GPVI–/– mice with the common human sepsis pathogen Klebsiella pneumoniae via the airways to induce pneumonia-derived sepsis. The GPVI liga...

Duvelisib is an oral dual inhibitor of phosphoinositide 3-kinase- (PI3K-) and PI3K- in late-stage clinical development for hematologic malignancy treatment. This phase 1 study evaluated maximum tolerated dose (MTD), pharmacokinetics, pharmacodynamics (PD), efficacy, and safety of duvelisib in 210 patients with advanced hematologic malignancies. In the dose escalation phase (n = 31), duvelisib 8 to 100 mg twice daily was administered, with MTD determined as 75 mg twice daily. In the expansion phase (n = 179), patients with indolent non-Hodgkin lymphoma (iNHL), chronic lymphocytic leukemia (CLL), or T-cell lymphoma (TCL) wer...

Community-acquired pneumonia (CAP) is the leading cause of mortality in children under 5 years of age globally. To improve the management of CAP, we must distinguish CAP from other common pediatric conditions and develop better diagnostic methods to detect the causative organism, so as to best direct appropriate resources in both industrialized and developing countries. Here, we review the diagnostic modalities available for identifying viruses and bacteria in the upper and lower respiratory tract of children, with a discussion of their utility and limitations in diagnosing CAP in children.

ConclusionVancomycin PAP MIC may be a more relevant predictor of patient outcomes in persistent bacteremic MRSA infections (e.g., IE). This susceptibility method is less applicable in other high inoculum infections with shorter bacteremia durations and higher mortality rates (e.g., pneumonia).

Publication date: Available online 21 February 2018 Source:The Lancet Neurology Author(s): Stefan Schwartz, Dimitrios P Kontoyiannis, Thomas Harrison, Markus Ruhnke Fungal infections of the CNS are challenging to treat and their optimal management requires knowledge of their epidemiology, host characteristics, diagnostic criteria, and therapeutic options. Aspergillus and Cryptococcus species predominate among fungal infections of the CNS. Most of these fungi are ubiquitous, but some have restricted geographical distribution. Fungal infections of the CNS usually originate from primary sites outside the CNS (eg, fungal pneu...
