Inflammatory Biomarkers Affecting Survival Prognosis in Patients Receiving Veno-Venous ECMO for Severe COVID-19 Pneumonia.

Severe COVID-19 pneumonia in which mechanical ventilation is unable to achieve adequate gas exchange can be treated with veno-venous ECMO, eliminating the need for aggressive mechanical ventilation which might promote ventilator-induced lung injury and increase mortality. In this retrospective observational study, 18 critically ill COVID-19 patients who were treated using V-V ECMO during an 11-month period in a tertiary COVID-19 hospital were analyzed. Biomarkers of inflammation and clinical features were compared between survivors and non-survivors. Survival rates were compared between patients receiving ECMO and propensity matched mechanically ventilated controls. There were 7 survivors and 11 non-survivors. The survivors were significantly younger, with a higher proportion of females, higher serum procalcitonin at ICU admission, and before initiation of ECMO they had significantly lower Murray scores, PaCO2, WBC counts, serum ferritin levels, and higher glomerular filtration rates. No significant difference in mortality was found between patients treated with ECMO compared to patients treated using conventional lung protective ventilation. Hypercapnia, leukocytosis, reduced glomerular filtration rate, and increased serum ferritin levels prior to initiation of V-V ECMO in patients with severe COVID-19 pneumonia may be early warning signs of reduced chance of survival. Further multicentric studies are needed to confirm these findings.

Trying to Survive A Serious Heart Condition in Time of COVID-19.

The world has suffered over the past year under COVID-19. Unfortunately, people still are getting sick from other, also severe, diseases. Although the COVID-19 infection is present, patients need treatment for other life-threatening conditions. We present the case of a 36-year-old patient with severe infective endocarditis with a large abscess of the aortic root, who also is COVID-19 positive. Definitive diagnostics and treatment were avoided due to COVID-19 infection. In the end, emergent surgery was indicated due to acute cardiac decompensation and the development of heart failure symptoms, and the patient recovered uneventfully after surgery.

Gastric tube ulcer perforating the pericardium after subtotal esophagectomy.

Subtotal esophagectomy with retrosternal transposition of the gastric tube to the neck was performed in a 62-year-old patient with squamous cell carcinoma of the proximal third of the esophagus. He developed a salivatory fistula in the early postoperative period that healed spontaneously. Five months later, the patient developed partial stenosis of the esophagogastric anastomosis which required recervicotomy and excision, after numerous failed dilatation attempts. Eighteen months later, the patient presented to the hospital for severe pain in the upper abdomen. Clinical work-up revealed pericardial perforation by the gastric tube ulcer necessitating emergent surgery and gastric tube removal. We present a patient who developed both early and late complications of subtotal esophagectomy with gastric tube transposition as well as a review of the literature.
