The prevalence of fungi in the respiratory tract of cystic fibrosis (CF) patients has risen. However, fungal surveillance is not routinely performed in most clinical centers in the United States, which may lead to an underestimation of the true prevalence of the problem. We conducted a prospective study comparing fungal detection rates for clinically important fungi (CIF) defined as Aspergillus species, Scedosporium species, Trichosporon species, and Exophiala dermatitidis in CF sputum using standard bacterial culture media and selective-fungal culture media, including Sabouraud dextrose agar with gentamicin (SDA), inhibitory mold agar (IMA), and brain-heart infusion agar (BHI) with chloramphenicol and gentamicin...

Alagille syndrome is a rare multisystem disorder affecting the liver, heart, vertebrae, eyes, and face. Alagille syndrome shares multiple phenotypic variants of other congenital or chronic childhood illnesses such as DiGeorge syndrome, Down syndrome, spina bifida, type 1 diabetes mellitus, and cystic fibrosis. All of these chronic illnesses have well-established links to psychiatric conditions. There are few community resources for Alagille patients, as it is an extremely rare condition. Despite the overlap with other chronic childhood illnesses, the psychiatric manifestations of Alagille syndrome have not been previously discussed in literature...

High fructose diet can cause cardiac hypertrophy and oxidative stress is a key mediator for myocardial hypertrophy. Disruption of cystic fibrosis transmembrane conductance regulator (CFTR) leads to oxidative stress. This study aims to reveal mitochondrial oxidative stress-related signaling pathway in high fructose-induced cardiac hypertrophy. Mice were fed high fructose to develop cardiac hypertrophy. Fructose and H2O2 were used to induce cardiomyocyte hypertrophy in vitro. Mitochondria-targeted antioxidant SkQ1 was applied to investigate the possible role of mitochondrial reactive oxygen species (ROS)...

BACKGROUND: Exercise testing is part of the regular assessment of patients with cystic fibrosis (CF). We aimed to evaluate (1) the convergent validity of the 1-min sit-to-stand (STS) test in CF by investigating its relationships with peak oxygen uptake (peak V̇O2 ), quadriceps strength, and quality of life and (2) to compare these associations with those of the 6-min walk test (6MWT). METHODS: Twenty-five adults with CF (FEV1 = 59 ± 24%) performed the STS test, the 6MWT, quadriceps strength assessment, and cardiopulmonary exercise test (CPET)...

In 2004, the U.S. Surgeon General declared that Thanksgiving would be National Family History Day, a day designed to encourage American families to learn about and create a written record of their family health history. Family history can identify those persons with a higher-than-average risk for many common diseases, such as heart disease, cancer, and type 2 diabetes. Having at least one first-degree relative with a disease can increase a person's risk twofold or more (1). Family history is also a determinant of less common diseases like sickle cell disease and cystic fibrosis (1)...

Left atrial (LA) dilation has been shown to be associated with atrial fibrillation (AF) in the adult population, with some studies indicating that larger LAs are more prone to AF recurrence. The relation of LA size to AF in the pediatric and young adult population has not been investigated. In this study, all pediatric patients (aged ≤22 years) who presented to Boston Children's Hospital from January 2002 to December 2012 with AF were reviewed. Patients with significant congenital heart disease, cardiomyopathies, proven channelopathies, previous cardiac surgery, end-stage renal disease, or severe lung disease/cystic fibrosis were excluded...

Cystic fibrosis is a complex multi-systemic chronic disease characterized by progressive organ dysfunction with development of fibrosis, possibly affecting the heart. Over the last four decades pathological, experimental, and clinical evidence points towards the existence of a specific myocardial involvement in cystic fibrosis. Multi-modality cardiac imaging, especially recent echocardiographic techniques, evidenced diastolic and/or systolic ventricular dysfunction in cystic fibrosis leading to the concept of a cystic fibrosis-related cardiomyopathy...

Alterations in myocardial wall texture stand out among ADPKD cardiovascular manifestations in hypertensive and normotensive patients. To elucidate their pathogenesis, we analyzed the cardiac phenotype in Pkd1(cond/cond)Nestin(cre) (CYG+) cystic mice exposed to increased blood pressure, at 5 to 6 and 20 to 24 weeks of age, and Pkd1(+/-) (HTG+) noncystic mice at 5-6 and 10-13 weeks. Echocardiographic analyses revealed decreased myocardial deformation and systolic function in CYG+ and HTG+ mice, as well as diastolic dysfunction in older CYG+ mice, compared to their Pkd1(cond/cond) and Pkd1(+/+) controls...

BACKGROUND: The overall life expectancy of women with cystic fibrosis (CF) is shorter compared with men with CF without accounting for lung transplant recipients. However, it is unclear how donor and recipient gender impact long-term outcomes in patients with CF who undergo lung transplantation. The purpose of this study was to determine if the gender disadvantage seen in women with CF before transplant continues to exist after lung transplant and if this is impacted by donor gender. METHODS: Patients with CF entered in the International Society for Heart and Lung Transplantation registry who were at least 18 years old and received a lung transplant between January 2000 and December 2012 were included and divided into groups based on donor-recipient gender combinations...

BACKGROUND: Acute pulmonary exacerbations are associated with progressive lung function decline and increased mortality in cystic fibrosis. The role of pulmonary vascular disease in pulmonary exacerbations is unknown. We aimed to assess the association between pulmonary artery enlargement (defined as pulmonary artery diameter to ascending aorta diameter [PA:A] ratio >1), a marker of pulmonary vascular disease, and exacerbations. METHODS: In this cohort study, we used clinical, CT imaging, and prospective exacerbation data from a previous prospective clinical trial (derivation cohort) and from The Prince Charles Hospital (TPCH; Brisbane, QLD, Australia) cystic fibrosis registry (validation cohort)...

BACKGROUND: A survival advantage has been demonstrated for lung transplantation (LTx) in the cystic fibrosis (CF) population, but children may be at higher risk of post-transplant mortality than adults. METHODS: The registry of the International Society for Heart and Lung Transplantation (ISHLT) was queried for lung transplants performed during the period 1998 to 2014 in patients with CF. Period differences were assessed by dividing the sample into LTxs performed between 2006 and 2014 and those performed between 1998 and 2005...
