An epidemic outbreak of Methicillin-resistant Staphylococcus Aureus (MRSA) infections affecting liver transplantation patients was detected in our hospital. In this study we describe the special characteristics of the infections and the results of prophylactic treatment with Vancomycin. Between april 1990 and december 1991, 47 patients with mean age of 54.4 +/- 10 years underwent liver transplantation. The patients were included in two chronological groups: 1) Group I: 20 patients not treated prophylactically with Vancomycin; 2) Group II: 27 consecutive patients treated with Vancomycin. Systematical cultures of body fluids for bacteria and fungi were done in every patient, and were repeated after 24 hours. The cultures were repeated again in case of sepsis. Group I patients had a significantly higher frequency of MRSA infections than group II patients. Furthermore, in patients with MRSA infection, independently of the group, duration of transplantation (p < 0.01), reoperations (p < 0.001) and prophylactic treatment with Vancomycin (p < 0.001) were significative factors. In conclusion, Vancomycin appears to be an elective prophylactic antibiotic in case of high risk of MRSA sepsis after liver transplantation.

Chimeric antigen receptor (CAR)-T cell therapies have revolutionized the landscape of cancer treatment, in particular in the context of hematologic malignancies. However, for solid tumors that lack tumor-specific antigens, CAR-T cells can infiltrate and attack nonmalignant tissues expressing the CAR target antigen, leading to on-target, off-tumor toxicity. Severe on-target, off-tumor toxicities have been observed in clinical trials of CAR-T therapy for solid tumors, highlighting the need to address this issue.

The development of surgical techniques, chemotherapy, biological agents, and multidisciplinary approaches have made patients with unresectable colorectal liver metastases eligible for surgery. Many strategies have been developed to allow patients for surgical resection (percutaneous portal vein embolization, liver venous deprivation, parenchyma-sparing liver surgery, reverse strategy, associating liver partition and portal vein ligation for staged hepatectomy, and liver transplantation), the only form of disease control and curative treatment.

In patients with synchronic liver colorectal metastasis, resection of the primary tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or hepatectomy first). Patients with no bowel occlusion and with extensive liver disease are advised neoadjuvant oncological therapy.

Complete removal of metastatic disease and maintenance of an adequate liver remnant remains the only treatment option with curative intent concerning colorectal liver metastases. Surgery impacts on the long-term prognosis and complications adversely affect oncological results. The actual morbidity involving this scenario is debatable and estimated to be ranging from 15% to 50%.

Cardiac allograft vasculopathy (CAV) remains a significant challenge after heart transplantation, necessitating effective surveillance methods. This review centers around the role of coronary computed tomography angiography (CCTA) in CAV surveillance, given its unique capabilities to visualize and quantify CAV in comparison with other imaging modalities, including invasive coronary angiography and intravascular ultrasound. CCTA has shown good diagnostic performance for detecting and monitoring CAV, exemplified by a higher sensitivity and negative predictive value compared with invasive coronary angiography.
