Vitamin C aids tendon healingThe effect of fibrin clot and C vitamin on the surgical treatment of Achilles tendon injury in the rat model✰.
In our investigation, we looked at how vitamin C, in combination with a fibrin clot, influences the healing of Achilles tendon injuries in rats. We used 52 adult Wistar-Albino rats and divided them into four distinct groups to assess various treatments.
The results showed that vitamin C, when paired with fibrin clot, significantly improved tendon healing. Not only did it enhance the mechanical strength of the tendon, but it also led to better histological and biochemical outcomes, suggesting a more robust healing process. We noted increased levels of important growth factors in the groups treated with fibrin clot and vitamin C.
Importantly, the findings indicated that vitamin C plays a beneficial role in recovery, especially when combined with other treatment strategies. While further research may be necessary to fully understand its isolated effects, the data suggests that vitamin C is a valuable component in the healing bundle for Achilles tendon injuries.

Vitamin C enhances blood clottingAscorbic acid improves thrombotic function of platelets during living donor liver transplantation by modulating the function of the E3 ubiquitin ligases c-Cbl and Cbl-b.
We sought to understand how ascorbic acid, commonly known as vitamin C, impacts blood clotting during living donor liver transplantation (LDLT). In our study, we analyzed blood samples from 21 recipients before and after their surgeries.
We employed a well-structured approach, using rotational thromboelastography (TEG) and western blot analysis to scrutinize fibrinolysis and the functionality of specific proteins involved in clotting. Blood samples were tested in three distinct groups, one receiving vitamin C, to see its effects on clot rigidity and fibrinolysis.
Our findings revealed that ascorbic acid notably reduced fibrinolysis, which refers to the breakdown of blood clots, and improved the rigidity of the clots formed. Additionally, we observed that levels of a protein called Cbl-b were higher in those receiving vitamin C, while another protein, c-Cbl, showed reduced phosphorylation. These functional changes might explain how vitamin C supports better clotting during surgeries.
This study indicates that vitamin C could be a beneficial treatment to consider during LDLT to manage hyperfibrinolysis, thus promoting better outcomes for patients undergoing these complex procedures.

ESA and iron enhance surgery outcomesUse of preoperative erythropoietin-stimulating agents is associated with decreased thrombotic adverse events compared to red blood cell transfusion in surgical patients with anaemia.
We aimed to understand how preoperative treatments like erythropoietin-stimulating agents (ESAs) and intravenous (IV) iron influence the risk of blood clots in surgical patients dealing with anaemia.
In our investigation, we found that patients who received ESAs—whether accompanied by IV iron or not—had lower risks of serious post-operative complications, including blood clots, compared to those who were given red blood cell transfusions. Specifically, those treated with ESAs without IV iron showed significant reductions in mortality and the occurrence of venous thromboembolic events.
Interestingly, when IV iron was combined with ESAs, it appeared to further enhance outcomes, notably improving survival rates. Our results suggest that combining these treatments might yield benefits for patients undergoing surgery, reflected in higher haemoglobin levels and fewer complications compared to traditional blood transfusions.

Magnetic stent-grafts improve healingMagnetic capture of blood outgrowth endothelial cells to the luminal surface of magnetizable stent-grafts promotes healing in a porcine pseudoaneurysm model.
We explored how magnetizable stent-grafts can improve healing in carotid artery pseudoaneurysms by investigating their ability to capture blood outgrowth endothelial cells.
In a porcine model, we compared magnetic stent-grafts with standard non-magnetic ones. The results showed that the magnetic stent-grafts not only occluded all nine pseudoaneurysms but also achieved better cell capture and endothelial growth.
Essentially, the magnetic properties enhanced the healing process, leading to less thrombosis compared to non-magnetic counterparts. This innovative approach could reduce complications associated with these medical devices.

Scurvy-related DVT treated with vitamin CPediatric scurvy case report: a novel presentation with deep vein thrombosis secondary to large bilateral spontaneous iliac subperiosteal hematomas.
We explored a unique case of a 14-year-old boy with autism who presented with deep vein thrombosis (DVT) due to large bilateral subperiosteal hematomas caused by vitamin C deficiency, known as scurvy. This rare situation is noteworthy as scurvy is typically associated with other symptoms, but here it led to an unusual complication of DVT.
During our investigation, we observed that after administering vitamin C replacement, the patient's condition improved significantly. Follow-up imaging showed that both the DVT and the hematomas resolved. This outcome suggests that vitamin C can potentially have a positive impact in cases where blood clots are related to underlying deficiencies.
However, we must clarify that while vitamin C treatment appeared beneficial in this specific situation, our findings are based on a single case. Thus, further research would be essential to understand its broader implications on DVT treatment and the role of vitamin C in blood clot scenarios.
