Remote endpoints for clinical trials in cystic fibrosis: Report from the U.S. CF foundation remote endpoints task force.

The COVID-19 pandemic necessitated a rapid shift in clinical research to perform virtual visits and remote endpoint assessments, providing a key opportunity to optimize the use of remote endpoints for clinical trials in cystic fibrosis. The use of remote endpoints could allow more diverse participation in clinical trials while minimizing participant burden but must be robustly evaluated to ensure adequate performance and feasibility. In response, the Cystic Fibrosis Foundation convened the Remote Endpoint Task Force (Supplemental Table 1), a multidisciplinary group of CF researchers with remote endpoint expertise and community members tasked to better understand the current and future use of remote endpoints for clinical research.

Estimating the Time Toxicity of Contemporary Systemic Treatment Regimens for Advanced Esophageal and Gastric Cancers.

(1) Background: The purpose of this study was to evaluate the time toxicity, or time spent in health care, of immunotherapy- versus chemotherapy-based regimens for metastatic esophageal and gastric cancers. (2) Methods: A literature search was conducted, and 18 phase III clinical trials of immune checkpoint inhibitors were selected for analysis. Health care days were calculated based on the number of days associated with receiving therapy and the adverse events reported in the clinical trials.

An Integrated Review of Carpal Tunnel Syndrome: New Insights to an Old Problem.

Carpal tunnel syndrome (CTS) is a common entrapment neuropathy characterized by pain, numbness, and impaired function of the hand due to compression of the median nerve at the level of the wrist. Although CTS can develop from repetitive strain, injury, or medical conditions, there are also congenital and genetic risk factors that can predispose individuals to the condition. With respect to anatomical factors, some individuals are born with a smaller carpal tunnel, which increases their susceptibility to median nerve compression.

Telemedicine and remote monitoring in cystic fibrosis.

Purpose Of Review: Guidelines for cystic fibrosis (CF) care recommend multidisciplinary teams see patients at least quarterly with frequent measurement of spirometry and collection of respiratory cultures. This can be burdensome for people with CF, particularly if they live far from a specialized care center. This has led to an interest in telehealth coupled with remote monitoring.

Biology of follicular lymphoma: insights and windows of clinical opportunity.

Follicular lymphoma (FL) is a heterogeneous disease, both clinically and biologically. The biological behavior and development of FL is a culmination of complex multistep processes underpinned by genetic and nongenetic determinants. Epigenetic deregulation through recurrent genetic alterations is now a recognized major biological hallmark of FL, alongside the t(14;18) translocation.

Going the Extra Mile: Why Clinical Research in Cystic Fibrosis Must Include Children.

This is an exciting time for research and novel drug development in cystic fibrosis. However, rarely has the adage, "Children are not just little adults" been more relevant. This article is divided into two main sections.

Cell-Based Therapy for the Treatment of Glioblastoma: An Update from Preclinical to Clinical Studies.

Glioblastoma (GB), an aggressive primary tumor of the central nervous system, represents about 60% of all adult primary brain tumors. It is notorious for its extremely low (~5%) 5-year survival rate which signals the unsatisfactory results of the standard protocol for GB therapy. This issue has become, over time, the impetus for the discipline of bringing novel therapeutics to the surface and challenging them so they can be improved.

The feasibility of home monitoring of young people with cystic fibrosis: Results from CLIMB-CF.

Background: CF is traditionally assessed in clinic. It is unclear if home monitoring of young people with CF is feasible or acceptable. The COVID-19 pandemic has made home monitoring more of a necessity.

Analysis of conventional and alternative CRISPR/Cas9 genome editing to enhance a single-base pair knock-in mutation.

Background: The use of CRISPR/Cas9 technologies in generating single-base pair knock-in mutations has recently exploded in the number of methods available. However, with the growing expansion of new technologies, it can be difficult to determine the best method for genome editing.

Results: In this study, we evaluated a number of CRISPR/Cas9 approaches for deriving cell lines with knock-in base pair edits to create a phosphorylation mutation and provide a breakdown of editing efficiencies and suggestions for improvement.

Telemedicine and cystic fibrosis: Do we still need face-to-face clinics?

There has been growing interest in telemedicine for cystic fibrosis over recent years based largely on convenience for patients and/or increasing the frequency of surveillance and early detection which, it is assumed, could improve treatment outcomes. During 2020, the covid-19 pandemic catalysed the pace of development of this field, as CF patients were presumed to be at high risk of infection. Most clinics adapted to digital platforms with provision of lung function monitoring and sample collection systems.

Cystic fibrosis transmembrane conductance regulator modulators for cystic fibrosis: a new dawn?

Cystic fibrosis (CF) is the most common life-limiting inherited condition in Caucasians. It is a multisystem autosomal recessive disorder caused by variants in the gene for cystic fibrosis transmembrane conductance regulator (CFTR) protein, a cell-surface localised chloride channel that regulates absorption and secretion of salt and water across epithelia. Until recently, the treatment for CF was predicated on ameliorating and preventing the downstream symptoms of CFTR dysfunction, primarily recurrent respiratory infections and pancreatic exocrine failure.

Potentiators and Correctors in Paediatric Cystic Fibrosis Patients: A Narrative Review.

Cystic fibrosis is the most common inherited condition in the Caucasian population and is associated with significantly reduced life expectancy. Recent advances in treatment have focussed on addressing the underlying cause of the condition, the defective production, expression and function of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Several drugs with different modes of action have produced promising results in clinical trials, and some have been incorporated into routine clinical care for specific patients in many countries worldwide.

Outdoor air pollution and cystic fibrosis.

Outdoor air pollution is increasingly identified as a contributor to respiratory and cardiovascular disease. Pro-inflammatory particles and gases are inhaled deep into the lungs, and are associated with impaired lung growth and exacerbations of chronic respiratory diseases. The magnitude of these effects are of interest to patients and families, and have been assessed in studies specific to CF.

Cystic fibrosis newborn screening: outcome of infants with normal sweat tests.

Newborn babies positively screened for cystic fibrosis (CF) (high serum immunoreactive trypsin (IRT) with DNA analysis) are referred for a diagnostic sweat test, which may be normal (sweat chloride <30 mmol/L). Unless two gene mutations are identified during Newborn screening (NBS), the babies are discharged from follow-up. We wished to check that none had subsequently developed symptoms suggestive of CF.

Current and future therapies for Pseudomonas aeruginosa infection in patients with cystic fibrosis.

Pseudomonas aeruginosa opportunistically infects the airways of patients with cystic fibrosis and causes significant morbidity and mortality. Initial infection can often be eradicated though requires prompt detection and adequate treatment. Intermittent and then chronic infection occurs in the majority of patients.

Non-BMD DXA measurements of the hip.

Hip fracture is one of the most serious complications of osteoporosis. More than 50% of hip and other fractures occur in patients without densitometric osteoporosis. Therefore, areal bone mineral density (aBMD) may not be the best way to assess fracture risk.

Current and future treatment options for cystic fibrosis lung disease: latest evidence and clinical implications.

Treatment for cystic fibrosis (CF) has conventionally targeted downstream consequences of the defect such as mucus plugging and infection. More recently, significant advances have been made in treating the root cause of the disease, namely a defective CF transmembrane conductance regulator (CFTR) gene. This review summarizes current pulmonary treatment options and highlights advances in research and development of new therapies.

Directed differentiation of human embryonic stem cells into corticofugal neurons uncovers heterogeneous Fezf2-expressing subpopulations.

Understanding how neuronal diversity is achieved within the cerebral cortex remains a major challenge in neuroscience. The advent of human embryonic stem cells (hESCs) as a model system provides a unique opportunity to study human corticogenesis in vitro and to identify the mechanisms that promote neuronal differentiation to achieve neuronal diversity in human brain. The transcription factor Fezf2 is necessary and sufficient for the specification of subcerebral projection neurons in mouse.

Splicing factor TRA2B is required for neural progenitor survival.

Alternative splicing of pre-mRNAs can rapidly regulate the expression of large groups of proteins. The RNA binding protein TRA2B (SFRS10) plays well-established roles in developmentally regulated alternative splicing during Drosophila sexual differentiation. TRA2B is also essential for mammalian embryogenesis and is implicated in numerous human diseases.
