Cardiac disease in cystic fibrosis

The ferret (Mustela putorius furo) is a small domesticated species of the family Mustelidae within the order Carnivora. The present article reviews and discusses the current state of knowledge about housing, care, breeding, and biomedical uses of ferrets. The management and breeding procedures of ferrets resemble those used for other carnivores. Understanding its behavior helps in the use of environmental enrichment and social housing, which promote behaviors typical of the species. Ferrets have been used in research since the beginning of the twentieth century...

INTRODUCTION: We conducted a study to determine the prevalence of structural heart disease in patients with CF, the characteristics of a cardiomyopathy not previously described in this population, and its possible relationship with nutritional deficiencies in CF. METHODS: We studied 3 CMP CF patients referred for heart-lung transplantation and a prospective series of 120 adult CF patients. All patients underwent a clinical examination, blood tests including levels of vitamins and trace elements, and echocardiography with evaluation of myocardial strain...

INTRODUCTION: Psoriasis is a chronic disease of the skin with a prevalence of 2% in the general population. The high prevalence of psoriasis has prompted the study of its comorbidities in recent decades. We designed a study to determine the prevalence of psoriasis in a large-scale, population-based cohort, to exhaustively describe its comorbidities, and to analyze which diseases are associated with psoriasis. METHODS: Retrospective, observational study based on the clinical information contained in the electronic health records of the individuals in the EpiChron Cohort with a diagnosis of psoriasis (31,178 individuals) in 2019...

INTRODUCTION: Patients with cystic fibrosis (CF) are living longer and may be considered for total hip arthroplasty (THA) or total knee arthroplasty (TKA). Perioperative outcomes and implant survival after these procedures performed for those with CF have not been previously described. METHODS: Using the M151 PearlDiver database, a large, national, administrative database, THA and TKA patients with and without CF were identified and matched 1:10 based on age, sex, and Elixhauser Comorbidity Index...

Lung transplantation is the only therapy for patients with end-stage lung disease. In advanced lung diseases such as cystic fibrosis (CF), life expectancy increases, and it is important to recognize extrapulmonary comorbidities. Cardiovascular involvement, including pulmonary hypertension, right-heart failure, and myocardial dysfunction, are manifest in the late stages of CF disease. Besides right-heart failure, left-heart dysfunction seems to be underestimated. Therefore, an optimal anesthesia and surgical management risk evaluation in this high-risk patient population is mandatory, especially concerning the perioperative use of mechanical circulatory support...

BACKGROUND: Although people living with cystic fibrosis (PwCF) often have some risk factors for cardiovascular disease, including diabetes and chronic inflammation, little is known about the long-term cardiac risk in this condition. We aimed to determine the characteristics, rates and outcomes for cardiac disease in CF. METHODS: We looked at rates and outcomes for cardiac disease in 5649 adult PwCF in the UK CF Registry and 6265 adult PwCF in TriNetX (a global federated database of electronic healthcare record data)...

"Lung perfusion" in the context of imaging conventionally refers to the delivery of blood to the pulmonary capillary bed through the pulmonary arteries originating from the right ventricle required for oxygenation. The most important physiological mechanism in the context of imaging is the so-called hypoxic pulmonary vasoconstriction (HPV, also known as "Euler-Liljestrand-Reflex"), which couples lung perfusion to lung ventilation. In obstructive airway diseases such as asthma, chronic-obstructive pulmonary disease (COPD), cystic fibrosis (CF), and asthma, HPV downregulates pulmonary perfusion in order to redistribute blood flow to functional lung areas in order to conserve optimal oxygenation...

MasR is a critical element in the RAS accessory pathway that protects the heart against myocardial infarction, ischemia-reperfusion injury, and pathological remodeling by counteracting the effects of AT1R. This receptor is mainly stimulated by Ang 1-7, which is a bioactive metabolite of the angiotensin produced by ACE2. MasR activation attenuates ischemia-related myocardial damage by facilitating vasorelaxation, improving cell metabolism, reducing inflammation and oxidative stress, inhibiting thrombosis, and stabilizing atherosclerotic plaque...

Tachypnoea in the newborn is common. It may arise from the many causes of the respiratory distress syndrome such as hyaline membrane disease, transient tachypnoea of the newborn, meconium aspiration etc. Congenital heart disease rarely presents with early tachypnoea on day one or two, in contrast to the early presentation of cyanosis, unless there is "pump" (ventricular) failure such as may occur in a cardiomyopathy/myocarditis, or as a result of severe obstruction to either ventricle. Space-occupying lesions within the chest, for example from a diaphragmatic hernia or a congenital cystic adenomatoid malformation, may present with early tachypnoea, as can a metabolic cause resulting in acidosis...

As the life expectancy improves in cystic fibrosis, cardiac dysfunction is becoming an important risk factor for morbidity and mortality. Here, the association of cardiac dysfunction with proinflammatory markers and neurohormones between cystic fibrosis patients and healthy children was investigated. Echocardiographic measurements of right and left ventricular morphology and functions together with levels of proinflammatory markers and neurohormones (renin, angiotensin-II, and aldosterone) were obtained and analysed in a study group of 21 cystic fibrosis children aged 5-18 years and compared with age- and gender-matched healthy children...

Long QT syndrome type 2 (LQT2) is a genetic disorder caused by mutations in the KCNH2 gene, also known as the human ether-a-go-go-related gene (hERG). Over 30% of hERG mutations result in a premature termination codon (PTC) that triggers a process called nonsense-mediated mRNA decay (NMD), where the mRNA transcript is degraded. NMD is a quality control mechanism that removes faulty mRNA to prevent the translation of truncated proteins. Recent advances in antisense oligonucleotide (ASO) technology in the field of cystic fibrosis (CF) have yielded significant progress, including the ASO-mediated comprehensive characterization of key NMD factors and exon-skipping therapy...

BACKGROUND: In many countries worldwide orphan drug regulations are installed but only the United States of America and Japan have an orphan device regulation. For many years surgeons have used off-label or self-assembled medical devices for the prevention, diagnosis or treatment of rare disorders. Four examples are given: an external cardiac pacemaker, a metal brace for clubfoot in newborns, a transcutaneous nerve stimulator and a cystic fibrosis mist tent. CONCLUSION: In this article we argue that we need authorized medical devices as well as medicinal products to prevent, diagnose and treat patients with life-threatening or chronically debilitating disorders with a low prevalence/incidence...

Cystic fibrosis (CF) is an autosomal recessive disease caused by different mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. It is the most common inherited disorder in the Caucasian population, with around 2000 mutations identified for the CFTR gene. The precise prevalence of CF in Arab countries remains unknown, with the prevalence of F508 del found to be a common type with other endemic mutations. We describe the case of a CF patient who was diagnosed at the age of seven years...

Background: Burkholderia gladioli (B gladioli) is a rare, gram-negative rod that was initially regarded as a plant pathogen. However, B gladioli has been reported as the primary pathogen causing pneumonia in organ transplant recipients and in patients with cystic fibrosis. We report a case of bacterial pneumonia caused by B gladioli in a patient hospitalized for coronavirus disease 2019 (COVID-19). Case Report: A 68-year-old male was admitted for acute hypoxic respiratory failure secondary to COVID-19 pneumonia...

Humanity has suffered from the coronavirus disease 2019 (COVID-19) pandemic over the past two years, which has left behind millions of deaths. Azithromycin (AZ), an antibiotic used for the treatment of several bacterial infections, has shown antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as well as against the dengue, Zika, Ebola, and influenza viruses. Additionally, AZ has shown beneficial effects in non-infective diseases such as cystic fibrosis and bronchiectasis...

Motivation and adherence are the main factors that limit participation in physiotherapy exercise sessions and airway clearance in cystic fibrosis (CF) population. One of the newly developed techniques is to use virtual reality (VR) games to increase motivation and adherence during exercise sessions for this population. However, this area is still poorly investigated. This review aims to evaluate, summarize, and review published literature regarding the effects of VR exercise on cardiopulmonary function and the use of VR games as a tool for airway clearance technique in CF population...

PATIENTS: This prospective study consisted of 32 children with mild cystic fibrosis and 30 age-matched healthy control participants. METHODS: Cardiac MRI was used to assess right ventricular volumes, anatomy, and function and to assessment of haemodynamic findings of pulmonary artery in the control and study groups...

BACKGROUND: Pediatric lung transplantation is performed in highly experienced centers due to the peculiar population characteristics. The literature is limited and not representative of individual countries' differences. The purpose of this study was to analyze the Italian experience. METHODS: A multicentric retrospective analysis was performed on 110 pediatric patients (<18 years old) who underwent lung transplantation from 1992 to 2019 at 9 Italian centers...

Fibrosis is characterized by the excessive extracellular matrix deposition due to dysregulated wound and connective tissue repair response. Multiple organs can develop fibrosis, including the liver, kidney, heart, and lung. Fibrosis such as liver cirrhosis, idiopathic pulmonary fibrosis, and cystic fibrosis caused substantial disease burden. Persistent abnormal activation of myofibroblasts mediated by various signals, such as transforming growth factor, platelet-derived growth factor, and fibroblast growh factor, has been recongized as a major event in the occurrence and progression of fibrosis...
