Introduction: For complete blood count, ethylenediaminetetraacetic acid (EDTA) is universally used and has been recognized as the most robust anticoagulant. However, it may lead to pseudothrombocytopenia (PTCT), due to the formation of platelet clumps, which is currently followed by resampling on sodium citrate. Other possible anticoagulants are citrate theophylline adenosine dipyridamole (CTAD) and MgSO.

Background: Thoracic and lumbar spinal fractures are common in trauma care, requiring accurate classification to guide appropriate treatment. While traditional teaching methods use static 2D images, there is a growing need for interactive tools to improve understanding. This study addresses the lack of interactive three-dimensional (3D) models for teaching the AO (Arbeitsgemeinschaft für Osteosynthesefragen) Spine classification for thoracic and lumbar fractures.

Chagas disease following infection with Trypanosoma cruzi is a major public health issue, with the disease spreading beyond endemic regions and becoming more global due to the migration of infected individuals. The currently available anti-parasitic drugs, nifurtimox and benznidazole, remain insufficiently evaluated for their efficacy in adult patients. A key challenge is the lack of markers for parasitological cure, which also precludes the development of new treatments.

Introduction: Spinal deformity in adults is a major public health problem. After failure of conservative treatment, correction and fusion surgery leads to clinical and radiological improvement. However, mechanical complications and more particularly - proximal junctional kyphosis (PJK) - are common with an incidence of 10%-40% depending on the studies.

Background: Therapeutic targets supported by genetic evidence from genome-wide association studies (GWAS) show higher probability of success in clinical trials. GWAS is a powerful approach to identify links between genetic variants and phenotypic variation; however, identifying the genes driving associations identified in GWAS remains challenging. Integration of molecular quantitative trait loci (molQTL) such as expression QTL (eQTL) using mendelian randomization (MR) and colocalization analyses can help with the identification of causal genes.

Article Synopsis
  • - Metabolic dysfunction-associated steatotic liver disease (MASLD) is prevalent among obese individuals and shows differences between sexes. A study sought to create a noninvasive blood test using mid-infrared (MIR) metabolic fingerprinting to diagnose metabolic dysfunction-associated steatohepatitis (MASH) in those with severe obesity.
  • - The study involved 382 patients undergoing bariatric surgery, with liver biopsies assessed to establish a scoring algorithm based on MIR spectroscopy. In women, MASH was diagnosed in 14.3% of cases, showing high sensitivity (86%) and specificity (81%) for correctly identifying the condition.
  • - For men, the test's performance was notably less effective, with a MASH diagnosis

Article Synopsis
  • Acute kidney injury (AKI) can progress to acute kidney disease (AKD) and potentially to chronic kidney disease (CKD), creating significant health risks, including cardiovascular complications.
  • In a mouse study, researchers found that kidney injury resulted in early heart and blood vessel dysfunction, marked by specific changes in protein expression and increased levels of harmful toxins over time.
  • The findings emphasize the importance of understanding the early effects of AKD on cardiovascular health to find ways to prevent future heart issues.

Article Synopsis
  • The blood-labyrinth barrier (BLB) is crucial for maintaining the ionic balance in the inner ear and preventing harmful substances from entering.
  • Recent studies have shown that dysregulation of BLB permeability is linked to various auditory issues, such as acoustic trauma and autoimmune diseases.
  • This study found that neutrophil extracellular traps (NETs) affect endothelial cells in the BLB, leading to increased permeability and changes in cell structure, suggesting a need for further research on NETs' role in auditory disorders.

While significant advances have been made in understanding renal pathophysiology, less is known about the role of glycosphingolipid (GSL) metabolism in driving organ dysfunction. Here, we used a small molecule inhibitor of glucosylceramide synthase to modulate GSL levels in three mouse models of distinct renal pathologies: Alport syndrome (Col4a3 KO), polycystic kidney disease (Nek8), and steroid-resistant nephrotic syndrome (Nphs2 cKO). At the tissue level, we identified a core immune-enriched transcriptional signature that was shared across models and enriched in human polycystic kidney disease.

Background: Lower extremity wounds in patients with diabetes are difficult to heal due to an overabundance of pro-inflammatory M1 macrophages, reduced phagocytosis of necrosed cells, and circulatory issues. Keratin biomaterials have been shown to address some of these concerns by encouraging the proliferation of anti-inflammatory M2 macrophages, thereby creating more favorable conditions for wound healing resembling those of patients without diabetes.

Objective: To investigate the effect of a novel human keratin matrix (HKM) on wound healing.
