Alström syndrome is a multisystemic disorder characterized by cone-rod dystrophy, hearing loss, obesity, insulin resistance and hyperinsulinemia, type 2 diabetes mellitus, dilated cardiomyopathy, and progressive hepatic and renal dysfunction. The cone-rod retinal dystrophy usually develops within a few weeks after birth. The authors examined a young boy with Alström syndrome by means of microperimetry and spectral domain optical coherence tomography (OCT). Instead of the typical alterations observed in cone-rod dystrophies, the characteristics of the central foveal tissue suggest signs of retinal immaturity, with only a single layer of short, thick cones and rods and immature short outer segments. High-speed and high-resolution spectral domain OCT allowed a detailed analysis of retinal layers in a young patient with Alström syndrome for the first time.

EZH2 inhibition induces pyroptosis via RHA-mediated S100A9 overexpression in myelodysplastic syndromes.

Myelodysplastic Syndromes (MDS) represent a group of heterogeneous myeloid clonal diseases derived from aberrant hematopoietic stem/progenitor cells. Enhancer of zeste homolog 2 (EZH2) is an important regulator in gene expression through methyltransferase-dependent or methyltransferase-independent mechanisms. Herein, we found EZH2 inhibition led to MDS cell pyroptosis through RNA Helicase A (RHA) down-regulation induced overexpression of S100A9, a key regulator of inflammasome activation and pyroptosis.

Background: The dynein cytoplasmic two heavy chain 1 (DYNC2H1) gene encodes a cytoplasmic dynein subunit. Cytoplasmic dyneins transport cargo towards the minus end of microtubules and are thus termed the "retrograde" cellular motor. Mutations in DYNC2H1 are the main causative mutations of short rib-thoracic dysplasia syndrome type III with or without polydactyly (SRTD3).

Background: Proton pump inhibitors (PPIs) are commonly used for managing gastroesophageal disorders but concerns about their potential association with increased stroke risk have emerged, especially among patients with pre-existing cardiovascular conditions such as acute coronary syndrome (ACS). This systematic review and meta-analysis aim to assess the risk of stroke associated with PPI use, stratified by the presence or absence of pre-existing CVD.
Methods: This review was conducted following the PRISMA guidelines and included studies up to March 2024 from PubMed, Embase, and Web of Science.
Identification of unmet information needs among families of critically ill patients and their association with post-intensive care syndrome-family: protocol for a single-center cross-sectional study.

Departments of Emergency and Critical Care Medicine, Graduate School of Medicine, Nippon Medical School, Tokyo, Japan.
Background: Families of critically ill patients in the intensive care unit (ICU) need a variety of information about the patient. Meeting these information needs improves the quality of communication between the family and ICU staff, as well as reduces the risk of post-intensive care syndrome-family (PICS-F). However, information needs continue to be unmet, and information regarding which specific information needs are met or unmet is insufficient.

Background: This study aimed to compare the effectiveness of the NoSAS, STOP-Bang, and Berlin scoring systems, which are utilized to predict obstructive sleep apnea syndrome (OSAS), in forecasting difficult airway management. Additionally, the study sought to determine which of these scoring systems is the most practical and effective for this purpose.
Methods: Following the ethics committee approval, preoperative NoSAS, STOP-Bang, and Berlin scores were calculated for 420 patients aged 18 years and older who were scheduled for tracheal intubation.
