Article Abstract

Relapse after allogeneic stem cell transplantation (alloSCT) represents a frequent complication in patients with myelofibrosis (MF). This retrospective study analysed 38 patients with JAK2-mutated MF who underwent alloSCT. Serial sensitive molecular assessments at regular intervals of JAK2 V617F revealed that a ≥2-fold increase in JAK2 variant allele frequency (VAF) at days +100 and +180 post-alloSCT was highly predictive of eventual morphological relapse. The integration of JAK2 VAF monitoring with chimerism analysis into post-alloSCT care represents a novel strategy for early detection of MF relapse, which may enable timely interventions and improve outcomes in such high-risk patients.

This meta-analysis aimed to evaluate the efficacy of automated activity monitoring (AAM) in detecting estrous expression and ovulatory status in cows during the voluntary waiting period (VWP). A comprehensive literature search was conducted in PubMed, ScienceDirect, and Google Scholar using specific search terms. Inclusion criteria focused on studies that assessed estrous expression within the VWP using modern AAM systems alongside blood progesterone (P4) measurements.

Kounis syndrome, also known as allergic myocardial infarction, is a rare but potentially life-threatening condition in which acute coronary events are triggered by an allergic reaction. The pathophysiology involves mast cell degranulation and the release of inflammatory mediators such as histamine, leukotrienes, and platelet-activating factor, leading to coronary vasospasm, myocardial ischemia, or infarction. We present the case of a female patient in her 80s with no prior history of coronary artery disease who developed anaphylaxis shortly after intravenous administration of co-amoxiclav in the emergency department.

The word-length effect refers to the finding that memory on many short-term/working memory tasks is better for words with fewer syllables than words with more syllables. The standard account attributes this result to a combination of decay offset by rehearsal: More short words can be rehearsed because they take less time to articulate. However, most studies have confounded length with lexical and other long-term memory factors that covary with length.

Background: Bedside ultrasound is increasingly utilized to assess muscle mass in critically ill patients, providing a noninvasive and real-time tool for early risk stratification. Muscle wasting is known to be associated with adverse outcomes in septic shock, but its prognostic value using ultrasound in this population remains underexplored. This study aimed to investigate the association between changes in rectus femoris cross-sectional area (CSA), assessed by bedside ultrasound, and 28-day mortality in patients with septic shock.
