RESUMEN
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. We assessed for risk factors of pretransplant anemia and identified associations with short-term post-transplant outcomes. RESULTS: Pretransplant anemia was associated with increased intraoperative transfusion of packed red blood cells and a trend towards increased index hospital length of stay and 1-year mortality. Conversely, pretransplant anemia was associated with a decreased incidence of acute cellular rejection. CONCLUSION: These preliminary data suggest that anemia may be a biomarker of altered inflammation in the host recipient and influences post-transplant outcomes.
RESUMEN
Venoarterial extracorporeal membrane oxygenation is increasingly used for mechanical circulatory support during lung transplant. Optimal intensity of intraoperative anticoagulation would be expected to mitigate thromboembolism without increasing bleeding and blood product transfusions. Yet, the optimal intensity of intraoperative anticoagulation is unknown. We performed a retrospective cohort study of 163 patients who received a bilateral lung transplant at a single center. We categorized the intensity of anticoagulation into 4 groups (very low to high) based on the bolus dose of unfractionated heparin given during lung transplant and compared the rates of intraoperative blood transfusions and the occurrence of thromboembolism between groups. When compared to the very low-intensity group, each higher intensity group was associated with higher red blood cell, fresh frozen plasma, and platelet transfusions. The occurrence of thromboembolism was similar across groups. These preliminary data suggest that lower intensity anticoagulation may reduce the rate of intraoperative blood transfusions, although further study is needed.

A hollow viscus injury is an uncommon but potentially dangerous intra-abdominal injury that can result from blunt abdominal trauma. It can be misdiagnosed in patient, particularly when the patient has other concerning findings. Also, diagnosis can be increasingly difficult in a patient with a pre-existing ventral hernia and chronic abdominal pain. In this case we present a 66-year-old women, with a history of a large ventral hernia and chronic abdominal pain, who presented to the emergency department after a motor vehicle crash (MVC). Patient denied abdominal tenderness at the time of presentation and the initial computed tomography (CT) did not demonstrate any abnormal findings within the abdomen. Patient later began experiencing increased abdominal pain and presented with a small bowel perforation within the hernia that required a bowel resection and hernia repair. A review of the literature reveals that not only are hollow viscus injuries rare but there appears to be few documented cases of viscus injuries occurring within a existing ventral hernia.
