Traumatic pulmonary hemorrhage is uncommon and rarely results in respiratory failure requiring mechanical circulatory support. Indications for extracorporeal membrane oxygenation (ECMO) in injured patients are not well-defined, but recent work indicates a potential survival benefit. Additionally, coughing-induced hemorrhage requires a complex sedation strategy.

Utilization of 10ºC static storage safely extended both ischemic time and travel radius in heart transplantation. A 57-year-old man with ischemic cardiomyopathy, a left ventricular assist device (LVAD), and end-stage renal disease was listed for combined heart-kidney transplant. The donor hospital in Anchorage, AK, was located approximately 2,700 nautical miles and 8 hours from the recipient center.

Background: Access to life-saving lung transplantation remains limited by a shortage of donor organs. We have previously described rehabilitation of discarded human donor lungs to a quality suitable for transplantation using cross-circulation of whole blood between xeno-support swine and human lungs. However, the immunologic implications of transplanting rehabilitated lungs remain unknown.

Optimized static cold storage has the potential to improve the preservation of organs most vulnerable to ischemia-reperfusion injury. Data from lung transplantation suggest that storage at 10 °C improves mitochondrial preservation and subsequent allograft function compared with conventional storage on ice. Using a porcine model of donation after circulatory death, we compared static storage of livers at 10 °C to ice.

Donation after circulatory death (DCD) livers face increased risks of critical complications when preserved with static cold storage (SCS). Although machine perfusion (MP) may mitigate these risks, its cost and logistical complexity limit widespread application. We developed the Dynamic Organ Storage System (DOSS), which delivers oxygenated perfusate at 10°C with minimal electrical power requirement and allows real-time effluent sampling in a portable cooler.

Article Synopsis
  • Indocyanine green angiography (ICGA) is crucial for diagnosing and tracking choroidal inflammation, particularly choroidal vasculitis, which is often missed by doctors not using this method during posterior uveitis assessments.
  • The study analyzes ICGA signs of choroidal vasculitis, highlighting two main patterns: choriocapillaritis, which shows hypofluorescent areas indicating inflammation, and stromal choroidal vasculitis, characterized by leaking hyperfluorescent vessels.
  • Overall, choroidal vasculitis is commonly found in patients with inflammatory choroid issues, and understanding its ICGA features can improve diagnosis and treatment outcomes.

Background: Anemia is a risk factor for increased morbidity and mortality in multiple medical conditions, yet the impact of pretransplant anemia in patients with advanced lung disease on post-transplant outcomes remains under-explored. We sought to determine whether pretransplant anemia serves as a marker of altered inflammation in the host and associates with short-term outcomes following lung transplantation.

Study Design And Methods: We performed a single-center, retrospective analysis of 238 lung transplant recipients.

Background: Equinus contractures can commonly be due to contractures of gastrocnemius muscle or combined contractures of the gastrocnemius-soleus Achilles tendon complex. The decision to release part or all of the gastrocnemius-soleus Achilles tendon complex is often assessed intraoperatively while the patient is under anesthesia. It remains unknown whether the administration of general anesthesia affects the measurement of passive ankle dorsiflexion.

  • This study investigates the costs associated with surgeries for acute Achilles tendon tears, focusing on factors influencing these expenses.
  • Using the Value Driven Outcome tool, researchers analyzed cost data from 224 patients who underwent surgical repairs and compared costs based on surgical techniques and locations.
  • Findings indicate that open repairs are significantly less costly than percutaneous techniques, and surgeries performed in ambulatory care centers offer lower total and facility costs compared to main academic hospitals.

Article Synopsis
  • Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is used for support during lung transplants, but the ideal level of anticoagulation needed to balance thromboembolism risk and bleeding is not established.
  • A study analyzed 163 patients, categorizing anticoagulation intensity into four levels based on heparin doses, to evaluate blood transfusion rates and thromboembolism occurrences.
  • Results indicated that higher anticoagulation intensity correlated with increased blood transfusions, while thromboembolism rates remained similar across all groups, suggesting that lower anticoagulation might be beneficial in reducing transfusions, but further research is required.

Article Synopsis
  • - The study examined the link between fibroblast growth factor 21 (FGF21) levels and mortality in over 5,500 participants without existing cardiovascular disease (CVD), revealing that higher FGF21 levels were correlated with increased all-cause mortality during an average follow-up of 17.7 years.
  • - While baseline FGF21 was associated with both CVD and non-CVD deaths, only the connection with non-CVD mortality remained significant after adjusting for traditional risk factors like age and health conditions.
  • - The findings suggest a need for further research on the role of FGF21 in predicting mortality, particularly its strong association with non-CVD deaths in individuals free of clinically evident CVD.
