    Abstract Bronchiolar disorders can be divided into 2 general categories: (1) airway disorders (cellular bronchiolitis and obliterative bronchiolitis) and (2) parenchymal disorders (respiratory bronchiolitis-interstitial lung disease, which occurs in smokers and is treatable with smoking cessation or corticosteroid therapy, and bronchiolitis obliterans organizing pneumonia, an inflammatory lung disease simultaneously involving the terminal bronchioles and alveoli). This article reviews the clinical findings and therapeutic management of bronchiolitis obliterans organizing pneumonia.

    Abstract Background: Often patients with chronic obstructive pulmonary disease (COPD) receive poor quality care with limited access to pulmonologists. We tested a novel intervention, INtegrating Care After Exacerbation of COPD (InCasE), that improved patient outcomes after hospitalization for COPD. InCasE used population-based identification of patients for proactive e-consultation by pulmonologists, and tailored recommendations with pre-populated orders timed to follow-up with primary care providers (PCPs). Although adoption by PCPs was high, we do not know how PCPs experienced the intervention.
    Objective: Our objective was to assess PCPs' experience with proactive pulmonary e-consults after hospitalization for COPD.
    Methods: We conducted a convergent mixed methods study among study PCPs at 2 medical centers and 10 outpatient clinics. PCPs underwent semi-structured interviews and surveys. We performed descriptive analyses on quantitative data and inductive and deductive coding based on prespecified themes of acceptability, appropriateness, and feasibility for qualitative data.
    Key results: We conducted 10 interviews and 37 PCPs completed surveys. PCPs perceived InCasE to be acceptable and feasible. Facilitators included the proactive consult approach to patient identification and order entry. PCPs also noted the intervention was respectful and collegial. PCPs had concerns regarding appropriateness related to an unclear role in communicating recommendations to patients. PCPs also noted a potential decrease in autonomy if overused.
    Conclusion: This evaluation indicates that a proactive e-consult intervention can be deployed to collaboratively manage the health of populations with COPD in a way that is acceptable, appropriate, and feasible for primary care. Lessons learned from this study suggest the intervention may be transferable to other settings and specialties.

    Abstract Reports of the characterization and understanding of bronchiolitis obliterans organizing pneumonia (BOOP) have continued at an accelerated rate for several years. The radiographic and high-resolution CT features of BOOP continue to be documented. There have been new insights into the pathogenesis of BOOP. An animal model has been developed. Video-assisted thoracoscopic biopsy has become a standard for confirming the diagnosis. Childhood BOOP has been described in several reports. Idiopathic BOOP continues to be the most common type; however, a variety of clinical settings such as inhalation of mold spores and associated disorders such as renal transplantation continue to be described. This paper provides an update of advances in the pathogenesis, radiographic features, clinical course, and categorization of the heterogeneity of BOOP.

    Abstract Bronchiolar lesions continue to be increasingly recognized as a cause of airflow obstruction. Thus, it is important to have a current update of the current clinical, radiographic, and immunologic perspective of these disorders. Diffuse panbronchiolitis has been reported to occur in the United States and Europe, and the anti-inflammatory action of erythromycin appears to be effective in management. Idiopathic bronchiolitis obliterans, post-fume or post-infectious, or connective tissue disorder bronchiolitis obliterans continues to be rare and often has a poor prognosis. Lung transplantation bronchiolitis obliterans continues to be the major complication and cause of mortality in transplant recipients. Risk factors of this form of chronic rejection include more frequent and more severe acute rejection and the coexistence of organizing pneumonia. The recognition of the distinctive differences among the bronchiolar airflow disorders continues to be essential for improved patient care, greater understanding of the pathogenesis, and development of therapeutic advances.

    Abstract Bronchiolitis obliterans organizing pneumonia (BOOP) is increasingly recognized as an important cause of diffuse infiltrative lung disease. It is a diagnostic consideration in patients with a febrile flu-like illness of a few weeks' duration and a roentgenogram showing bilateral patchy infiltrates that are not responsive to a typical course of antibiotics. It is defined as granulated tissue plugs within lumens of small airways that extend into alveolar ducts and alveoli. Clinically, a flu-like illness, cough, and crackles are common. Pulmonary function studies of patients show a decreased vital capacity, normal flow rates (except in smokers), and a decreased diffusing capacity. It is generally idiopathic, but it may occur during the resolution of a viral or mycoplasma pneumonia. It is also associated with a variety of systemic illnesses and clinical settings. These include the connective tissue disorders, antineoplastic and other drugs, and immunological disorders, as well as bone marrow and lung transplantation. There are numerous related disorders, including human immunodeficiency virus infection, radiation therapy, thyroiditis, and alcoholic cirrhosis. In idiopathic BOOP, complete resolution occurs in 65% to 85% of patients treated with corticosteroid therapy. This type of therapy is often effective in patients with associated systemic disorders or in other clinical settings, but there may be limited or no response in patients with dermatomyositis, immunosuppression, or interstitial opacities at the lung bases. Respiratory failure leading to death may occur in 5% of patients. It is important to add BOOP to the differential diagnosis of febrile, noninfectious illnesses that are mimics of pneumonia.

    Abstract Bronchiolar lesions are becoming increasingly recognized as an important cause of airflow obstruction. For this reason, it is helpful to have an update of the current clinical, radiographic, and immunologic perspective. Among the bronchiolar airflow disorders, diffuse panbronchiolitis is related to HLA antigen Bw54, and low-dose, long-term erythromycin appears to be effective therapy. Bronchiolitis obliterans can be classified histologically as constrictive bronchiolitis and as proliferative bronchiolitis obliterans. Idiopathic, postfume, postinfectious, and connective tissue disease bronchiolitis obliterans continue to be rare and often have a poor prognosis. Bronchiolitis obliterans associated with lung transplantation is undergoing intensive investigation with regard to pathogenesis, immunologic study, early detection, and treatment. The lesion appears to be a form of chronic organ rejection. The recognition of the distinctive differences among the bronchiolar airflow disorders by clinicians and clinical investigators is essential for improved patient care, for a greater understanding of the pathogenesis of the disorder, and for development of new therapeutic advances.

    Abstract The specific source of high burdens of selenium (Se) and mercury (Hg) in several bird species at Great Salt Lake (GSL) remain unknown. Frequent co-located water and brine shrimp samples were collected during 2016 through 2017 to identify potential correlations of element concentrations among brines and brine shrimp, a keystone species in the GSL. Like many aquatic systems, GSL is characterized by elevated methylmercury (MeHg) in deep waters. However, in contrast to thermally-stratified aquatic systems, biota in the salinity-stratified GSL do not reside in its deep waters, obscuring the presumed relationship between elevated MeHg in biota and in the deep brine. Brine shrimp and water column (shallow and deep, filtered and unfiltered) samples were collected from six sites spanning the South Arm of GSL approximately every other month. Mercury concentrations in brine shrimp (on average 89% of which is MeHg) were correlated only with total mercury in surface filtered water, and displayed little spatial variability, but consistent seasonal trends across the two sampled years. In contrast to Hg, temporal correspondence was observed between Se concentrations in brine shrimp and those in all water samples regardless of filtering and depth, with maxima and minima at higher-than-seasonal frequency. The data suggest a spatially diffuse source of bioavailable mercury to the shallow brine that responds to seasonal influences, for which the underlying deep brine, surficial sediments, and overlying atmosphere were evaluated in terms of potential temporal correspondence to shallow brine and brine shrimp Hg concentrations, as well as potential to mix across the extent of the shallow brine. Bioaccumulation factors were at the low end of those reported for marine systems, and decreased at higher trace element concentrations in water.

In the past few years and moving forward, glycosylation is increasingly being implicated in the pharmacodynamics and therapeutic efficacy of therapeutic proteins. This article provides illustrative examples of drugs that have already been improved through glycoengineering including cytokines exemplified by erythropoietin (EPO), enzymes (ectonucleotide pyrophosphatase 1, ENPP1), and IgG antibodies (e.g., afucosylated Gazyva®, Poteligeo®, Fasenra™, and Uplizna®). In the future, the deliberate modification of therapeutic protein glycosylation will become more prevalent as glycoengineering strategies, including sophisticated computer-aided tools for “building in” glycans sites, acceptance of a broad range of production systems with various glycosylation capabilities, and supplementation methods for introducing non-natural metabolites into glycosylation pathways further develop and become more accessible.
