Autism is clinically defined by challenges with social language, including difficulties offering on-topic language in a conversation. Similar differences are also seen in genetically related conditions such as fragile X syndrome (FXS), and even among those carrying autism-related genes who do not have clinical diagnoses (e.g.

Radiation oncology is among the most data-driven specialties in medicine. Recently, a wealth of peer-reviewed data has been published supporting the treatment of oligometastatic malignancies, demonstrating improved survival with metastasis-directed therapy, such as stereotactic body radiation therapy (SBRT), when combined with appropriate patient selection and treatment. However, there are currently few, if any, established guidelines that synthesize the abundance of data specific to radiotherapy into a single, easily accessed resource for clinicians.

Narrative is an important communication skill for sharing personal experiences and connecting with others. Narrative skills are often impacted in autism spectrum disorder (ASD) and have important consequences for social interactions and relationships. Subtle differences in narrative have also been reported among first-degree relatives of autistic individuals, suggesting that narrative may also be an etiologically important language-related skill that is influenced by genes associated with ASD.

This is the final of four papers updating standards for the care of people with CF. That this paper "Planning a longer life" was considered necessary, highlights how much CF care has progressed over the past decade. Several factors underpin this progress, notably increased numbers of people with CF with access to CFTR modulator therapy.

Article Synopsis
  • Pediatric urolithiasis is rare and usually linked to specific anatomical or metabolic issues, with this study examining emergency department (ED) admissions for renal colic among children and its potential relationship with climate.
  • A retrospective analysis of ED visits from 2010 to 2020 found a total of 609 admissions, showing a general decline over the years, with peaks in 2012 and 2018.
  • The research concluded that, unlike adults, seasonal variations and climate changes did not influence renal colic admissions in children, indicating different factors may be at play in this younger demographic.

Article Synopsis
  • - This paper is part of a series updating standards of care for cystic fibrosis (CF), emphasizing the importance of recognizing and managing various CF health issues despite advancements like CFTR modulators.
  • - It highlights the need for multidisciplinary care to address ongoing extrapulmonary issues such as diabetes, liver disease, and increased cancer risk, which require regular screenings.
  • - Mental and emotional support is crucial for individuals with CF and their families, especially during challenging times, and planning for end-of-life care should be approached with sensitivity and compassion.

DUS measurements for popliteal artery aneurysms (PAAs) specifically can be time-consuming, error-prone, and operator-dependent. To eliminate this subjectivity and provide efficient segmentation, we applied artificial intelligence (AI) to accurately delineate inner and outer lumen on DUS. DUS images were selected from a cohort of patients with PAAs from a multi-institutional platform.

This is the second in a series of four papers updating the European Cystic Fibrosis Society (ECFS) standards for the care of people with CF. This paper focuses on establishing and maintaining health. The guidance is produced using an evidence-based framework and with wide stakeholder engagement, including people from the CF community.

Article Synopsis
  • Advances in cystic fibrosis (CF) diagnosis focus on improvements in newborn bloodspot screening, gene analysis, and understanding CFTR-related disorders.
  • These developments highlight the importance of timely and accurate diagnosis for access to variant-specific therapy, which can significantly benefit those with eligible CFTR gene variants.
  • The guidance in this paper updates previous standards and emphasizes the growing necessity for proper diagnosis as future trials for variant-specific therapies are anticipated.

Introduction: We have recently validated a meatal Stenosis (MS) severity grading system that is based on physical examination.

Objectives: The study objective was to examine the correlation between this grading system, patients' urinary symptoms, uroflowmetry and postvoid residual parameters.

Study Design: Patients referred for our clinic for urinary and non-urinary complaints, were prospectively enrolled.

Purpose: To evaluate postoperative serum thyroglobulin (Tg) as a reliable tumor marker in low-risk differentiated thyroid cancer (DTC).

Methods: Two hundred and three patients met the selection criteria of >18 years old; who had undergone total or near total thyroidectomy; had a postoperative Tg, and had undergone I pre ablation whole body scan (PA-WBS). The primary endpoint was the correlation between Tg level and functional remnant thyroid tissues.

Purpose: Variation in protocols for axillary sentinel lymph node (SLN) mapping exists. We strive to evaluate the effectiveness of reduction in number of injections on reducing procedural pain, while maintaining nodal detection.

Methods: Over 7 years, the number of periareolar injections performed was reduced stepwise from 4 to 1.

Difficulties with pragmatic language (i.e., language in social contexts, such as conversational ability) are a noted characteristic of the language profiles of both fragile X syndrome (FXS) and autism spectrum disorder (ASD), conditions which show significant phenotypic overlap.

Background: Adherence to treatment by adolescents and adults with cystic fibrosis (CF) is often poor.

Objectives: To assess the impact of a focused clinical intervention on adherence in individual patients, including help in problem-solving key barriers to adherence. To implement a patient-centered problem-solving intervention using CF My Way tools.

Rationale: Early-onset adolescent depression is related to poor prognosis and a range of psychiatric and medical comorbidities later in life, making the identification of a priori risk factors for depression highly important. Increasingly, dysregulated levels of immune and neuroendocrine markers, such as C-reactive protein (CRP) and cortisol, have been demonstrated as both precursors to and consequences of depression. However, longitudinal research with adolescent populations is limited and demonstrates mixed immuno-endocrine-depression links.

Atypical visual attention patterns have been observed among carriers of the fragile X mental retardation gene () premutation (PM), with some similarities to visual attention patterns observed in autism spectrum disorder (ASD) and among clinically unaffected relatives of individuals with ASD. Patterns of visual attention could constitute biomarkers that can help to inform the neurocognitive profile of the PM, and that potentially span diagnostic boundaries. This study examined patterns of eye movement across an array of fixation measurements from three distinct eye-tracking tasks in order to investigate potentially overlapping profiles of visual attention among PM carriers, ASD parents, and parent controls.

Purpose: To identify preferences of patients and referring physicians for direct patient communication and notification of radiologic study results.

Methods: An anonymous survey was conducted of patients undergoing outpatient radiologic imaging studies and their referring physicians. The voluntary surveys elicited responses regarding preferences on a 5-point Likert scale (Strongly disagree, disagree, neutral, agree and strongly agree), as well as indicated by responding yes or no to specific questions.
