Summary: The aim of this study was to familiarize clinicians with the terms cystic fibrosis transmembrane conductance regulator related metabolic syndrome (CRMS) and cystic fibrosis screen positive inconclusive diagnosis (CFSPID), and to highlight the monitoring and outcomes of children with these designations. A literature review was performed to gather relevant articles, and the results showed that despite newborn screening programs for cystic fibrosis, the diagnosis remains uncertain for some infants. CRMS/CFSPID was established as a unified definition in 2016, but longer longitudinal studies are needed to determine the appropriate follow-up for these children. It is important for pediatricians to be knowledgeable about this condition and for children to be in contact with their local CF center.

Summary: As of December 2009, cystic fibrosis (CF) newborn screening (NBS) is performed in all 50 US states and the District of Columbia. Widespread implementation of CF newborn screening (CFNBS) in the US and internationally has brought about new and varied challenges. Advances in genetic testing have provided an opportunity for earlier identification of babies with CF through CFTR sequencing, improving long-term outcomes through prompt treatment and intervention.

Summary: This cross-sectional study aimed to evaluate the cutoff values of immunoreactive trypsinogen (IRT) and investigate the relationship between IRT values and clinical characteristics in children with cystic fibrosis (CF). The study included data from children with positive newborn screening (NBS) from 2015 to 2021. Sensitivity and specificity of IRT cutoff values were assessed, and the positive predictive value (PPV) was determined. The study found that while the sensitivity of CF NBS was high, the PPV was significantly lower than expected. Revising the NBS strategy may help overcome false-positive results.

Summary: This study evaluated whether the implementation of cystic fibrosis newborn screening leads to equitable timeliness of initial evaluation. The study compared the age at the first event (AFE) between infants of different races and ethnicities (Group 1) and white non-Hispanic infants (Group 2). The study found that differences in AFE for infants with CF from historically marginalized groups may exacerbate long-standing health disparities.

Summary: Disruptions of FOXP2 can cause severe speech disorder known as childhood apraxia of speech (CAS). This study examined individuals with pathogenic FOXP2-only variants and found that speech disorders, including CAS, were prevalent in these cases. Other comorbidities such as feeding difficulties, motor impairment, anxiety, depression, and sleep disturbance were also observed. The study emphasizes the importance of FOXP2 in understanding the neurobiological basis of speech disorder.

Summary: Patient care experiences play a crucial role in the successful implementation of genomics in paediatric care. A scoping review was conducted to understand parents' experiences and needs regarding genetic testing for rare diseases in their children. The review revealed that parents valued feeling cared for, consistent relationships with clinicians, empathic communication, updated information during the waiting period for test results, and access to support resources following result disclosure. Strategies to address unmet needs were proposed, but evidence on their effectiveness was limited. This emphasizes the need for rigorous interventions and the integration of genomics into paediatric care.

Summary: Genomic medicine is being implemented globally, and a genomic-competent health workforce is needed. A survey of Australian non-genetics physicians revealed that confidence and engagement with genomic medicine were influenced by factors such as specialty, continuing genomics education, and genomics research experience. Respondents who had completed genomics education and were engaged in genomic medicine reported higher confidence and were more likely to prefer genomic testing with genetics services support. A progression of genomic competence aligned with service delivery models and workplace learning could facilitate the adoption of genomic tests.

Summary: This study conducted qualitative interviews with cancer patients and providers to identify gaps in clinical care and propose care delivery solutions for the return of secondary germline findings. The responses of patients varied depending on the amount of pre-test counseling they received, and providers identified insufficient clinic time as a major barrier to pretest education. Online support tools and standardized pre-test education models were favored by providers. There were differing perspectives on how pre-test education should be integrated into clinical workflows, but agreement on the inclusion of differences between somatic and germline testing, likelihood of medically actionable findings, and the possibility of being referred to a genetics provider.
