Objective: This study aims to explore the clinical features and molecular diagnosis of FBN1-related acromelic dysplasia in Chinese patients.
Methods: The clinical and genetic features of three FBN1-related acromicric dysplasia (AD)/geleophysic dysplasia (GD) Chinese patients from two families were reviewed, and comprehensive medical evaluations were performed. Targeted next-generation sequencing was used to detect genetic mutations associated with short statures, including FBN1. Sanger sequencing was used to determine the de novo mutation origin.
Results: Patient 1 presented with short stature, short and stubby hands and feet, mild facial dysmorphism, hepatomegaly, delayed bone age and beak-like femoral heads. Patient 2 and this patient's father merely presented with short stature, wide and short hands, and beak-like femoral heads. One novel mutation, c.5272G>T(p.D1758Y), and one known mutation, c.5183C>T(p.A1728V), were identified in these patients.
Conclusion: The clinical features varied among these patients. The variant c.5272G>T(p.D1758Y) is a novel mutation.

Executive functions can be classified into processes of inhibition, working memory and shifting, which together support flexible and goal-directed behaviour and are crucial for both current and later-life outcomes. A large body of literature has identified distinct brain regions critical to performing each of these functions. These findings are however predicated on a piecemeal and single-task approach.

Objectives: The lack of definitive biomarkers presents a significant challenge for chemo-immunotherapy in extensive-stage small-cell lung cancer (ES-SCLC). We aimed to identify key genes associated with chemo-immunotherapy efficacy in ES-SCLC through comprehensive gene expression analysis using machine learning (ML).
Methods: A prospective multicenter cohort of patients with ES-SCLC who received first-line chemo-immunotherapy was analyzed.
Contribution of Open Access Databases to Intensive Care Medicine Research: Scoping Review.

Background: Intensive care units (ICUs) handle the most critical patients with a high risk of mortality. Due to those conditions, close monitoring is necessary and therefore, a large volume of data is collected. Collaborative ventures have enabled the emergence of large open access databases, leading to numerous publications in the field.

We All Need at Least One Friend Who Understands What We Do Not Say: A Scoping Review of Friendship and Augmentative and Alternative Communication.

Department of Library, The University of Tennessee Health Science Center, Memphis.
Purpose: The purpose of this scoping review was to understand what is known about the friendships of individuals who use augmentative and alternative communication (AAC) devices. Because communication is important to friendship, severe communication impairment may impact the establishment or maintenance of friendships in unique and important ways.
Method: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for scoping reviews and Covidence software using an established set of operationally defined inclusion criteria supported the identification of the 46 papers included in this review.
