Racial disparities in lung transplantation for cystic fibrosis in the era of highly effective modulator therapy.

Background: Highly effective modulator therapies (HEMT) including ivacaftor (IVA) and elexacaftor/tezacaftor/ivacaftor (ETI) have transformed treatment for people with cystic fibrosis (pwCF). However, non-HEMT-responsive mutations are more common in pwCF of non-White race/ethnicity; introduction of HEMT might have exacerbated racial/ethnic disparities in CF care.

Methods: Using the Scientific Registry of Transplant Recipients, we identified all lung transplant candidates and recipients 05/2005-12/2022 and categorized them by diagnosis (CF/non-CF), race/ethnicity (non-Hispanic White/Black/Hispanic) and era [Pre-HEMT (2005-1/30/2012), IVA (1/31/2012-10/30/2019), ETI (10/31/2019-12/31/2022)].

Donor sequence number is not associated with worse lung transplant outcomes regardless of transplant center case volume.

Background: Potential lung transplantation (LTx) recipients are assigned a donor sequence number (DSN) based on their position on the match list. Since a higher DSN offer has already been declined for other recipients, some providers may assume that a high DSN connotates poorer allograft quality. This study evaluated the association between DSN and outcomes, the correlation between transplant program case volume and the utilization of higher DSN lungs, and whether LTx outcomes differ between lower- and higher-volume programs.

Higher Hospitalization Costs and Fewer Routine Discharges in the Medicaid Expansion Era for Lung Transplant Recipients.

Background: In January 2014, states expanded Medicaid access under the Affordable Care Act. We studied the financial implications of this policy on lung transplantation, a costly procedure.

Methods: Lung transplant (LT) hospitalizations were identified within the National Inpatient Sample (2005-2020).

Utilization and outcomes of nonintubated extracorporeal membrane oxygenation as a bridge to lung transplant.

Background: Nonintubated extracorporeal membrane oxygenation (ECMO) has been increasingly utilized for patients with severe respiratory failure. Since data on its use as a bridge to lung transplant remain limited, we evaluated its use in a national cohort.

Methods: Adult lung-only transplant recipients bridged with ECMO May 4, 2005 to March 8, 2023 in the United Network for Organ Sharing database were categorized by use of ECMO and mechanical ventilation (MV) at transplant (ECMO+MV vs ECMO-only).

Impact of variable titer COVID-19 convalescent plasma and recipient SARS-CoV2-specific humoral immunity on survival in hospitalized patients.

COVID-19 convalescent plasma (CCP) was one of the first therapies to receive emergency use authorization for management of COVID-19. We assessed the effectiveness of CCP in a propensity-matched analysis, and whether the presence of antibodies in the recipient at the time of treatment or the titer of antibodies in the administered CCP influenced clinical effectiveness. In an inpatient population within a single large health system, a total of 290 CCP patients were matched to 290 controls.

Skipping Breakfast and Academic Grades, Persistent Feelings of Sadness or Hopelessness, and School Connectedness Among High School Students - Youth Risk Behavior Survey, United States, 2023.

Breakfast consumption is positively associated with academic achievement and diet quality among students, whereas skipping breakfast has been linked with poor mental health. Data from CDC's 2023 nationally representative Youth Risk Behavior Survey were used to describe how often high school students ate breakfast in the past 7 days and the associations between skipping breakfast every day (ate breakfast on 0 of the past 7 days), experiencing persistent feelings of sadness or hopelessness, school connectedness, and self-reported grades. Prevalence estimates and corresponding 95% CIs were calculated, and t-tests were used to identify differences within demographic groups (e.

Cystic fibrosis foundation position paper: Redefining the CF care model.

Specialized care is provided to people with cystic fibrosis (pwCF) by interdisciplinary teams nested within the CF Foundation's accredited care center network. This network allows for standardization of the care model, implementation of clinical care guidelines, efficient communication, and outcomes reporting. Recent developments have impacted this care model.

Outcomes of single vs double lung retransplantation in patients with cystic fibrosis.

Background: Patients requiring lung transplant for cystic fibrosis (CF) may require retransplant due to limited graft survival and otherwise excellent life expectancy. Optimal transplant strategy for this population, including single vs double lung retransplant, has not been established.

Methods: We performed a retrospective analysis of the United Network for Organ Sharing/Organ Procurement and Transplant Network (UNOS/OPTN) database to identify adult lung retransplant recipients from 2005 to 2021 with a primary diagnosis of CF.

A Retrospective, Longitudinal Registry Study on the Long-Term Durability of Ivacaftor Treatment in People with Cystic Fibrosis.

Introduction: Ivacaftor (IVA) has been shown to change the trajectory of cystic fibrosis (CF) disease progression by slowing the rate of lung function decline in clinical studies. Long-term real-world data help to confirm the durability of this response.

Methods: This non-interventional, longitudinal study used data from the US CF Foundation Patient Registry to describe the annualized rate of change in lung function in people with CF receiving IVA.

Hospitalists' perception of their communication with primary care providers - survey results from six hospitals in Central Switzerland.

Objectives: Due to the increasing complexity of the healthcare system, effective communication and data exchange between hospitalists (in-hospital physicians) and primary care physicians (PCPs) is both central and challenging. In Switzerland, little is known about hospitalists' perception of their communication with PCPs. The primary objective was to assess hospitalists' satisfaction with their communication with PCPs.

Challenges With School Meal Provisions in K-12 Public Schools: Findings From the National School COVID-19 Prevention Study.

School meals play a vital role in supporting student health. Access to school meals was disrupted during COVID-19-related school closures, impacting student nutritional intake and household food insecurity. Data from the National School COVID-19 Prevention Study Survey and school staff focus groups were used to examine challenges to school meal provision in K-12 public schools.

Investigation of CFTR Function in Human Nasal Epithelial Cells Informs Personalized Medicine.

We broaden the clinical versatility of human nasal epithelial (HNE) cells. HNEs were isolated from 10 participants harboring () variants: 9 with rare variants (Q359R [=2], G480S, R334W [=5], and R560T) and 1 harboring R117H;7T;TG10/5T;TG12. Cultures were differentiated at the air-liquid interface.

Impact of dual thoracic recovery from circulatory death donors on heart and lung transplant outcomes.

Objectives: Concomitant heart and lung recovery can result in increased operative complexity, ischemic time, and competition for resources and anatomic territory. Dual thoracic recovery from circulatory death donors may have additional risks that are not fully understood. We investigated the effects of dual heart and lung recovery from circulatory death donors on thoracic transplant outcomes.

The use of diagnostic ultrasound by primary care physicians in Switzerland - a cross-sectional study.

Background: Diagnostic ultrasound has become a bedside tool widely available to many primary care physicians (PCPs) in Europe. It is often used as point-of-care ultrasonography (POCUS) in this setting. In Switzerland, certain POCUS examinations are listed as learning objectives in existing ultrasound training programs (we defined these examinations as swissPOCUS = sPOCUS).

Long-term impact of ivacaftor on mortality rate and health outcomes in people with cystic fibrosis.

Background: Ivacaftor (IVA) has been shown to improve lung function and other clinical outcomes in people with cystic fibrosis (CF). A decade of real-world IVA availability has enabled the examination of long-term outcomes with this treatment. This retrospective, longitudinal cohort study investigated the impact of IVA on mortality rate and health outcomes among people with CF in the US.

Impact of age at ivacaftor initiation on pulmonary outcomes among people with cystic fibrosis.

Background: Ivacaftor (IVA) improves lung function and other extrapulmonary outcomes in people with cystic fibrosis (CF). However, the effect of initiating IVA at earlier versus later ages has not been studied.

Methods: We conducted an observational cohort study of people in the US CF Foundation Patient Registry aged ≥6 years with ≥1 CF transmembrane conductance regulator-gating mutation to compare the effects of initiating IVA at earlier ages on per cent predicted forced expiratory volume in 1 s (ppFEV) and pulmonary exacerbation (PEx) outcomes.

Debunking the July Effect in lung transplantation recipients.

Objective: The "July Effect" is a theory that the influx of trainees from July to September negatively impacts patient outcomes. We aimed to study this theoretical phenomenon in lung transplant recipients given the highly technical nature of thoracic procedures.

Methods: Adult lung transplant hospitalizations were identified within the National Inpatient Sample (2005-2020).

National utilization, trends, and lung transplant outcomes of static versus portable ex vivo lung perfusion platforms.

Background: This study compared utilization and outcomes of the 2 widely utilized ex vivo lung perfusion (EVLP) platforms in the United States: a static platform and a portable platform.

Methods: Adult (age 18 years or older) bilateral lung-only transplants utilizing EVLP between February 28, 2018, and December 31, 2022, in the United Network for Organ Sharing database were included. Predischarge acute rejection, intubation at 72 hours posttransplant, extracorporeal membrane oxygenation at 72 hours posttransplant, primary graft dysfunction grade 3 at 72 hours posttransplant, 30-day mortality, and 1-year mortality were evaluated using multivariable regressions.

Outcomes of Recipients Aged 65 Years and Older Bridged to Lung Transplant With Extracorporeal Membrane Oxygenation.

Extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplant (BTT) has been used for critically ill candidates with excellent outcomes, but data on this strategy in older recipients remain limited. We compared outcomes of no BTT, mechanical ventilation (MV)-only BTT, and ECMO BTT in recipients of greater than or equal to 65 years. Lung-only recipients of greater than or equal to 65 years in the United Network for Organ Sharing database between 2008 and 2022 were included and stratified by bridging strategy.

Health-Related Quality of Life Outcome Measures in Individuals With Hereditary Hemorrhagic Telangiectasia: A Scoping Review.

Background: Studies evaluating health-related quality of life (HRQOL) in patients with hereditary hemorrhagic telangiectasia (HHT) have expanded rapidly in the past decade. These studies have evaluated QOL aspects ranging from the general QOL for patients living with HHT to intervention-specific outcomes. However, few tools have been fully validated across the spectrum of disease manifestations and interventions in HHT.

The Impact of Donor Smoking on Primary Graft Dysfunction and Mortality after Lung Transplantation.

Primary graft dysfunction (PGD) is the leading cause of early morbidity and mortality after lung transplantation. Prior studies implicated proxy-defined donor smoking as a risk factor for PGD and mortality. We aimed to more accurately assess the impact of donor smoke exposure on PGD and mortality using quantitative smoke exposure biomarkers.
