Therapeutic plasma exchange (TPE) is a standard treatment in Guillain-Barré syndrome. TPE may require exogenous fluid for replacement of plasma and, depending on the equipment used, varying extracorporeal volumes. Potential adverse effects include allergic reaction, infection, and hypotension. From September 1993 to December 1997, we treated 16 patients with Guillain-Barré syndrome by a newly developed method of automated double filtration plasmapheresis (DFPP). Patients (ten males and six females, age ranged from 16 to 73) suffering from acute ascending motor weakness and fulfilling the diagnostic criteria for GBS were chosen for DFPP. Each patient received at least five sessions of apheresis in 7 to 10 days and approximately 2.5 to 3.0 L of plasma was treated in each session. Patients were evaluated by disability grade according to a Hughes scale. The mean grade of disability was 3.62 at treatment and improved to 2.37 four weeks after the start of DFPP. The median time to grade 2 (walk without support) was 19 days. There were five patients (41.6%) in need of respirator support. The median time to weaning off the respirator was 9 days. Only two patients (12.5%) could not reach grade 2 at the end of 6 months. Our results were comparable to previously published results of TPE. We conclude that DFPP may be as effective as TPE in the treatment of GBS.

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: Adipose tissue plays a critical role in the development of metabolically unhealthy obesity (MUO), with distinct adipose depots demonstrating functional differences. This study aimed to investigate the unique characteristics of subcutaneous (SA) and visceral adipose tissue (VA) in MUO.
Methods: Paired omental VA and abdominal SA samples were obtained from four male patients with MUO and subjected to Four-Dimensional Data Independent Acquisition (4D-DIA) proteomic and lysine acetylation (Kac) analyses.

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.

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.
