As the majority of individuals with CF have chronic lung disease, this population was initially considered to be at high risk for severe disease as infection with a multitude of viruses has proven to cause pulmonary exacerbation. SARS-CoV-2 virus has proven challenging to study given the multiple disease manifestations, range of severity, and wave-like phenomenon that varies geographically.

A major CF breakthrough was the approval of elexacaftor/tezacaftor/ivacaftor (ETI) in 2019, which has been shown to improve symptoms and lung function in the CF population, and decrease pulmonary exacerbations. The purpose of this study was to analyze longitudinal changes in respiratory symptoms over 24 months in ETI-treated and untreated PwCF with ALD Symptoms were measured among CF adults with ppFEV < 40% (N = 48, 24 ETI-treated, 24 untreated) using the CFRSD-CRISS and the CFQ-R [respiratory].

Study Design: The Trauma ALgorithm Examining the Risk of massive Transfusion (Trauma ALERT) study was an observational cohort study.
The use of local anesthetics for improved pain management is well established. However, significant morbidity may be caused by local anesthetic systemic toxicity (LAST) from inadvertent intravascular injection or excessive dosing of local anesthetics. Despite incomplete understanding of the mechanism of action of intravenous lipid emulsions (ILE), their use has become a first-line therapy for treating LAST.
View Article and Find Full Text PDFBackground: Lung transplantation is a common therapeutic option for individuals with cystic fibrosis (CF) and advanced lung disease, yet many individuals with CF are not appropriately referred for evaluation. The present study sought to enhance CF transplant referral guidelines by integrating patient-centered input to identify possible psychosocial barriers contributing to suboptimal referral for appropriate CF transplant candidates.
Methods: As a component of developing the Cystic Fibrosis Foundation (CFF) Lung Transplant Referral Consensus Guidelines, we convened a focus group of lung transplant recipients with CF and two spouses of CF recipients.
Culture-independent studies of cystic fibrosis lung microbiota have provided few mechanistic insights into the polymicrobial basis of disease. Deciphering the specific contributions of individual taxa to CF pathogenesis requires comprehensive understanding of their ecophysiology at the site of infection. We hypothesize that only a subset of CF microbiota are translationally active and that these activities vary between subjects.

Our objective was to understand uptake, experiences, benefits, and limitations of a dashboard to support patient-clinician partnerships within the cystic fibrosis (CF) community.
Methods: People living with CF (PwCF) and clinicians co-designed a dashboard that displayed patient-reported and clinical data.
A critical limitation in the management of chronic polymicrobial infections is the lack of correlation between antibiotic susceptibility testing (AST) and patient responses to therapy. Underlying this disconnect is our inability to accurately recapitulate the environment and complex polymicrobial communities However, emerging evidence suggests that, if modeled and tested accurately, interspecies relationships can be exploited by conventional antibiotics predicted to be ineffective by standard AST. As an example, under conditions where relies on cocolonizing organisms for nutrients (i.

This system regulates behaviors including but not limited to virulence and biofilm formation. We focused on , a human opportunistic pathogen that is involved in acute and chronic lung infections and which disproportionately affects people with cystic fibrosis.

Methods: Information from a database associated with a large tertiary medical center was used to assess adult patients with CF CRS and non-CF CRS (total, n = 102; CF CRS, n = 31; non-CF CRS, n = 71). Radiologic evidence of neo-osteogenesis was measured using the Global Osteitis Scoring Scale (GOSS), and mucosal disease was assessed using the Lund-Mackay score (LMS) by 2 independent reviewers who were blinded to the patient's disease state.
Background: The relation between malnutrition and pulmonary death in patients with cystic fibrosis (CF) has resulted in intensive nutritional intervention over the last few decades, leading to a significant decline in underweight and the emergence of overweight/obesity as a potential new problem.
Methods: We performed a cross-sectional database analysis of 484 adults with CF seen at the University of Minnesota CF Center between January 2015-January 2017, to determine the prevalence and pulmonary/cardiovascular risk factors associated with overweight and obesity in this population.
Results: Mean age was 35.
Background: The increasing life expectancy of individuals with Cystic Fibrosis (CF) is likely to be associated with new age-related challenges, colorectal cancer (CRC) most notably; recent consensus recommendations for CRC screening published in 2018 represent an important early step in addressing the emerging awareness of CF as a gastrointestinal cancer syndrome. These recommendations, however, need to be further refined based on more systematic data. We discuss an illustrative first-ever case of synchronous CRC arising in a post-lung transplant individual with CF within the recommended surveillance interval after a well-documented prior normal colonoscopy.

Methods: The CF Foundation organized a multidisciplinary committee to develop CF Lung Transplant Referral Consensus Guidelines. Three workgroups were formed: timing for transplant referral; modifiable barriers to transplant; and transition to transplant care.
New sources of operational data are leading to novel healthcare delivery system design and opportunities to support operational planning and decision-making. Technologies such as real time locating systems (RTLS) provide a unique view and understanding of how healthcare delivery settings behave and respond to operational design changes. In this paper RTLS data from an outpatient clinical setting is leveraged to identify the appropriate number of scheduled providers in order to improve the utilization of the clinical space while balancing the negative effects of clinic congestion.

Background: Indirect evidence suggests that sinonasal secretions are aspirated into the lungs of patients with cystic fibrosis (CF), contributing to infection, subsequent tissue damage, and decreased lung function. Our objective is to determine whether sinonasal secretions are transferred to the lungs in patients with CF-related sinus disease and healthy subjects, particularly in the recumbent position and during sleep.
Methods: We performed a prospective, controlled trial to detect pulmonary aspiration of radiolabeled albumin applied to the nasal mucosa of study subjects with chronic sinusitis related to CF and control subjects without sinus disease.
Objectives: Chronic pancreatitis (CP) is an infrequent but debilitating complication associated with CFTR mutations. Total pancreatectomy with islet autotransplantation (TPIAT) is a treatment option for CP that provides pain relief and preserves β-cell mass, thereby minimizing the complication of diabetes mellitus. We compared outcomes after TPIAT for CP associated with CFTR mutations to CP without CTFR mutations.

Here, we compare bacterial communities of matched sinus and lung mucus samples from cystic fibrosis (CF) subjects undergoing endoscopic surgery for treatment of chronic sinusitis.
Methods: Mucus from one maxillary sinus and expectorated sputum were collected from twelve patients.
Chronic lung infections in cystic fibrosis (CF) patients are composed of complex microbial communities that incite persistent inflammation and airway damage. Despite the high density of bacteria that colonize the lower airways, nutrient sources that sustain bacterial growth in vivo, and how those nutrients are derived, are not well characterized. In this study, we examined the possibility that mucins serve as an important carbon reservoir for the CF lung microbiota.
