Successful Colchicine Therapy in a Patient With Follicular Bronchiolitis Presumed to Be Asthma.
Abstract Follicular bronchiolitis (FB) is a rare small-airway pathology that is associated mainly with connective tissue diseases. This case report presents a new, diagnosed, different airway disease in a non-smoker with rheumatoid arthritis in remission who was treated for presumed asthma, but was not controlled. She was ultimately diagnosed with FB after video-assisted thoracoscopic surgery. The clinical findings of FB were controlled successfully by colchicine after she did not respond to systemic steroid therapy. This is the first case report of FB associated with rheumatoid arthritis that responded to colchici...

Muscle Impairment in Neuromuscular Disease Using an Expiratory/Inspiratory Ratio.
CONCLUSIONS: Healthy individuals and subjects with NMDs showed higher PEmax in comparison to PImax regarding the PEmax/PImax ratio. Based on the ratio, it is possible to state that NMDs show different patterns of respiratory muscle strength loss. PEmax/PImax ratio is a useful parameter to assess the impairment of respiratory muscles in a patient and to customize rehabilitation and treatment.

Neurally Adjusted Ventilatory Assist Improves Patient-Ventilator Synchrony in a Patient With Tetanus and Unstable Diaphragmatic Electrical Activity.
Abstract A 79-y-old man with generalized tetanus was admitted to the ICU. A left-forearm wound was surgically debrided, and the wound was closed. On postoperative day 1, after the patient experienced opisthotonos and convulsions, endotracheal intubation was performed. Propofol and diazepam were infused but failed to stop the convulsions. Morphine, midazolam, dantrolene, and rocuronium were used to ameliorate the muscle spasms. Magnesium sulfate was also infused. On postoperative day 15, patient-ventilator asynchrony was apparent. The patient showed recurrent tachypnea and bradypnea, which seemed typical of Cheyne-S...

Interaction between dimer interface residues of native and mutated SOD1 protein: a theoretical study.
Abstract Cu-Zn superoxide dismutase 1 (SOD1) is a highly conserved bimetallic protein enzyme, used for the scavenging the superoxide radicals (O2 (-)) produced due to aerobic metabolism in the mitochondrial respiratory chain. Over 100 mutations have been identified and found to be in the homodimeric structure of SOD1. The enzyme has to be maintained in its dimeric state for the structural stability and enzymatic activity. From our investigation, we found that the mutations apart from the dimer interface residues are found to affect the dimer stability of protein and hence enhancing the aggregation and misfolding te...

Comparison of Turnaround Time (TAT) and Time to Oseltamivir Discontinuation between Two Respiratory Viral Panel Testing (RVP) Methodologies.
Abstract Multiplex PCR is highly sensitive and provides a more rapid turnaround time (TAT) compared to other respiratory viral testing methodologies. Our microbiology laboratory switched from the Luminex xTAG® RVP (detects 12 respiratory viruses with an assay time of 8.5 hours) to the Biofire Diagnostics, Inc. FilmArray®-RP (detects 17 respiratory viral and 3 bacterial targets with an assay time of 1.2 hours). We sought to compare the TAT between the two respiratory viral panels (RVP) performed at different frequencies and determine time to discontinuation of empiric oseltamivir. All adult patients with an RVP te...

Compound 48/80 acts as a potent mucosal adjuvant for vaccination against Streptococcus pneumoniae infection in young mice.
In this study, the adjuvanticity of C48/80 was evaluated when intranasally co-administrated with a pneumococcal vaccine candidate strain SPY1 in a young mice model in comparison with a classical mucosal adjuvant cholera toxin (CT) and a relatively safe mucosal adjuvant Pam2CSK4. All three adjuvants enhanced antibody responses, whereas serum IgG titers were maintained at a stable level during the 3 months after the last immunization only in the SPY1+C48/80 and SPY1+CT groups. Furthermore, both the SPY1+CT group and the SPY1+C48/80 group induced strong Th17 immune response. Notably, C48/80 showed the exceptional ability to p...

Intubation after noninvasive ventilation failure in chronic obstructive pulmonary disease: associated factors at emergency department presentation
Objective: Noninvasive ventilation (NIV) is a common practice in acute hypercapnic respiratory failure (AHRF) because of exacerbation of chronic obstructive pulmonary disease (COPD). However, a recent study has shown that patients who require invasive mechanical ventilation (IMV) after failure of NIV experience high mortality rates (up to 30%). Therefore, the aim of this study is to determine the parameters, specifically for emergency department (ED) presentation, associated with the transition from NIV to IMV because of NIV failure. Patients and methods: This is a 4-year retrospective cohort study in the EDs of two Dutch ...

Evaluation of lung recruitment maneuvers in acute respiratory distress syndrome using computer simulation
Conclusions: There appears to be significant scope for reducing the peak levels of PEEP originally specified in the MRS and hence to avoid exposing the lung to unnecessarily high pressures. More generally, our study highlights the huge potential of computer simulation to assist in evaluating the efficacy of different recruitment maneuvers, in understanding their modes of operation, in optimizing RMs for individual patients, and in supporting clinicians in the rational design of improved treatment strategies.

NADPH Oxidase‐Dependent NLRP3 Inflammasome Activation and its Important Role in Lung Fibrosis by Multiwalled Carbon Nanotubes
In this study, three long aspect ratio (LAR) materials (MWCNTs, single‐walled carbon nanotubes, and silver nanowires) are used to compare with spherical carbon black and silver nanoparticles for their ability to trigger oxygen burst activity and NLRP3 assembly. All LAR materials but not spherical nanoparticles induce robust NADPH oxidase activation and respiratory burst activity in THP‐1 cells, which are blunted in p22phox‐deficient cells. The NADPH oxidase is directly involved in lysosomal damage by LAR materials, as demonstrated by decreased cathepsin B release and IL‐1β production in p22phox‐deficient cells. ...

Cerebral microhaemorrhages secondary to fat embolus syndrome in sickle cell disease
Introduction Fat embolus syndrome (FES) is a distinct pattern of clinical symptoms and signs following circulation of fat globules, or emboli, in the lung parenchyma and peripheral circulation. It leads to multisystem dysfunction, most commonly involving the lungs, skin, brain and kidneys. It is usually seen following trauma; however, it is a rare but potentially fatal and under-diagnosed complication of bone marrow infarction in patients with sickle cell disease. Neurological involvement forms part of the classical clinical triad of presentation, composed of respiratory changes, neurological abnormalities and a petechial ...

Endotoxin-induced lung alveolar cell injury causes brain cell damage
Sepsis is the most common cause of acute respiratory distress syndrome, a severe lung inflammatory disorder with an elevated morbidity and mortality. Sepsis and acute respiratory distress syndrome involve the release of inflammatory mediators to the systemic circulation, propagating the cellular and molecular response and affecting distal organs, including the brain. Since it has been reported that sepsis and acute respiratory distress syndrome contribute to brain dysfunction, we investigated the brain-lung crosstalk using a combined experimental in vitro airway epithelial and brain cell injury model. Conditioned medi...

A motion-compensated image filter for low-dose fluoroscopy in a real-time tumor-tracking radiotherapy system
In the real-time tumor-tracking radiotherapy system, a surrogate fiducial marker inserted in or near the tumor is detected by fluoroscopy to realize respiratory-gated radiotherapy. The imaging dose caused by fluoroscopy should be minimized. In this work, an image processing technique is proposed for tracing a moving marker in low-dose imaging. The proposed tracking technique is a combination of a motion-compensated recursive filter and template pattern matching. The proposed image filter can reduce motion artifacts resulting from the recursive process based on the determination of the region of interest for the next frame ...

Abstract B07: Metabolic liabilities of human colon carcinoma spheroids are different compared to standard 2D cultures
The search for metabolic liabilities in tumor cells is typically performed in standard 2D cultures. This approach lacks the 3D context and heterogeneity of tumor tissue in vivo, which has significant impact on their metabolic behavior. One solution to modeling complex tumor cell interactions is to use cultured tumor spheroids. To assess bioenergetic function in individual spheroids, a modified, 96-well plate for the Seahorse Bioscience XFe96 Extracellular Flux Analyzer was created. Here, we demonstrate the capability of measuring mitochondrial oxygen consumption – a measure or mitochondrial respiration – and extracellu...

Abstract B87: Prolyl hydroxylase and the regulation of reactive oxygen species (ROS) levels in cancer cells
Hypoxic microenvironments frequently exist within many solid tumors with oxygen levels fluctuating temporally and spatially from normoxia to hypoxia. The response to hypoxia in human cells is mainly regulated by hypoxia-inducible factors or HIFs, a family of transcription factors which orchestrate signalling events promoting cancer stem cells, leading to angiogenesis and increased tumorigenesis. Several events conspire together to stabilize HIF-αs to become constitutively expressed in many cancer cell types, regardless of oxygen levels. Prolyl hydroxylases (PHDs) play a crucial role in HIF regulation by hydroxylating HIF ...
