Ficolins, a group of oligomeric lectins consisting of three isoforms (H-, L- and M-ficolin), contribute to innate immunity via activating the complement pathway and/or acting directly as opsonins against pathogens and apoptotic cells. Because apoptotic cells likely drive the development of systemic sclerosis (SSc) partly through innate immunity, we assessed the clinical association of serum H-ficolin levels in SSc patients. Despite no difference in serum H-ficolin levels between SSc and control subjects, SSc patients with decreased serum H-ficolin levels tended to have a higher prevalence of interstitial lung disease (ILD)...

PURPOSE: Interstitial lung disease is a common extra-articular manifestation of rheumatoid arthritis (RA-ILD) and is associated with significant morbidity and mortality. However, limited data exist regarding predictors of mortality. We sought to examine the prognostic value of the high-resolution computed tomography (HRCT) patterns in patients with RA-ILD. MATERIALS AND METHODS: RA-ILD patients with HRCT patterns of usual interstitial pneumonia (UIP) or nonspecific interstitial pneumonia (NSIP) were identified among a longitudinal cohort of individuals evaluated at National Jewish Health...

Diagnosing fibrotic interstitial lung disease (ILD) requires multidisciplinary integration of clinical, radiological, and pathological features with assignment of a consensus classification. The current approach lacks a standardized ontology and therefore results in diagnostic heterogeneity. The objectives of this international working group perspective are to describe limitations of the current approach to fibrotic ILD diagnosis and to develop an ontological framework for standardizing the diagnostic classification...

Interstitial lung diseases (ILD) comprise an array of heterogeneous parenchymal lung diseases that are associated with a spectrum of pathologic, radiologic and clinical manifestations. There are ILDs with known etiologies and those that are idiopathic, making treatment strategies challenging. Prognosis can vary according to the type of ILD but many exhibit gradual progression with an unpredictable clinical course in individual patients as seen in idiopathic pulmonary fibrosis and the phenomenon of "acute exacerbation"(AE)...

The Mongolian gerbil (Meriones unguiculatus) has become a key species in investigations of the neural processing of sound localization cues in mammals. While its sound localization has been tested extensively under free-field stimulation, many neurophysiological studies use headphones to present signals with binaural localization cues. The gerbil's behavioral sensitivity to binaural cues, however, is unknown for the lack of appropriate stimulation paradigms in awake behaving gerbils. We close this gap in knowledge by mimicking a headphone stimulation; we use free-field loudspeakers and apply cross-talk cancellation techniques to present pure tones with binaural cues via "virtual headphones" to gerbils trained in a sound localization task...

S-nitrosoglutathione reductase (GSNOR), or ADH5, is an enzyme in the alcohol dehydrogenase (ADH) family. It is unique when compared to other ADH enzymes in that primary short-chain alcohols are not its principle substrate. GSNOR metabolizes S-nitrosoglutathione (GSNO), S-hydroxymethylglutathione (the spontaneous adduct of formaldehyde and glutathione), and some alcohols. GSNOR modulates reactive nitric oxide (•NO) availability in the cell by catalyzing the breakdown of GSNO, and indirectly regulates S-nitrosothiols (RSNOs) through GSNO-mediated protein S-nitrosation...

As a modern phenomenon, there is currently limited understanding of the possible toxic effects and broader implications of electronic nicotine delivery systems (ENDS). Large volumes of aerosolized particles are inhaled during "vaping" and there are now an increasing number of case reports demonstrating toxic effects of ENDS, as well as human studies demonstrating impaired lung function in users. This article presents a case of respiratory bronchiolitis interstitial lung disease (RB-ILD) precipitated by vaping in a 33-year-old male with 10 pack years of traditional cigarette and prior treatment for mixed germ cell tumour...

Pulmonary fibrosis is a severe condition with no cure and limited therapeutic options. Better understanding of its pathophysiology is needed. Recent studies have suggested that pulmonary fibrosis may be driven by accelerated aging-related mechanisms. Sirtuins (SIRTs), particularly SIRT1, -3, and -6, are well-known mediators of aging, however limited data exist on the contribution of sirtuins to lung fibrosis. We assessed the mRNA and protein levels of all seven known sirtuins in primary lung fibroblasts from patients with idiopathic pulmonary fibrosis (IPF) and systemic sclerosis-associated interstitial lung disease (SSc-ILD) in comparison with lung fibroblasts from healthy controls...

BACKGROUND: Pulmonary vein reconnection (PVR) still determines recurrences of atrial fibrillation after contact force (CF)-guided pulmonary vein isolation. We studied whether acute PVR (adenosine and waiting time) and late PVR (at repeat) are explained by incomplete transmurality and contiguity within the deployed radiofrequency circle. METHODS AND RESULTS: We analyzed 42 CF-guided ipsilateral pulmonary vein isolation procedures. For each radiofrequency tag within the circle, we collected data reflecting lesion depth (time of application, power, impedance drop [Δ-Imp], CF, force-time integral [FTI], and ablation index [AI]) and contiguity (automated interlesion distance [ILD])...

We longitudinally examined the influence of anti-tumor necrosis factor (TNF)-α treatment on serum levels of KL-6 and surfactant protein-D (SP-D). The study group comprised 22 patients with psoriasis treated with infliximab or adalimumab and with no history of interstitial lung disease (ILD). KL-6 and SP-D levels were measured in serum samples. Twelve of the 22 patients (55%) showed at least a 20% increase in KL-6 levels compared with baseline. Of these 12 patients, none exhibited any signs of ILD on chest computed tomography and nine who showed an increase in KL-6 levels (75%) showed at least a 20% increase in SP-D levels...

A Doppler radar operating as a Phase-Locked-Loop (PLL) in frequency demodulator configuration is presented and discussed. The proposed radar presents a unique architecture, using a single channel mixer, and allows to detect contactless vital signs parameters while solving the null point issue and without requiring the small angle approximation condition. Spectral analysis, simulations, and experimental results are presented and detailed to demonstrate the feasibility and the operational principle of the proposed radar architecture...
