Background:
Post-transplant diabetes mellitus (PTDM) is a risk factor for poor outcomes after kidney transplantation (KT). However, the outcomes of KT have improved recently. Therefore, we investigated whether PTDM is still a risk factor for mortality, major atherosclerotic cardiovascular events (MACEs), and graft failure in KT recipients.
Methods:
We studied a retrospective cohort of KT recipients (between 1994 and 2017) at a single tertiary center, and compared the rates of death, MACEs, overall graft failure, and death-censored graft failure after KT between patients with and without PTDM using Kaplan-Meier analysis and a Cox proportional hazard model.
Results:
Of 571 KT recipients, 153 (26.8%) were diagnosed with PTDM. The mean follow-up duration was 9.6 years. In the Kaplan- Meier analysis, the PTDM group did not have a significantly increased risk of death or four-point MACE compared with the non-diabetes mellitus group (log-rank test, P=0.957 and P=0.079, respectively). Multivariate Cox proportional hazard models showed that PTDM did not have a negative impact on death or four-point MACE (P=0.137 and P=0.181, respectively). In addition, PTDM was not significantly associated with overall or death-censored graft failure. However, patients with a long duration of PTDM had a higher incidence of four-point MACE.
Conclusion
Patient survival and MACEs were comparable between groups with and without PTDM. However, PTDM patients with long duration diabetes were at higher risk of cardiovascular disease.

Gastric hepatoid adenocarcinoma is a rare adenocarcinoma that develops in the stomach. The prognosis of gastric hepatoid adenocarcinoma is poorer than that of ordinary gastric adenocarcinoma. Here, we report the first case of human epidermal growth factor receptor 2 (HER2)-positive gastric hepatoid adenocarcinoma in Korea. A 57-year-old male presented with abdominal distension and underwent endoscopic gastric biopsy and percutaneous core needle liver biopsy. The pathological findings were consistent with HER2-positive gastric hepatoid adenocarcinoma. He received six cycles of chemotherapy with cisplatin-capecitabine plus trastuzumab, which is a HER2 targeted agent. After chemotherapy, a follow-up abdominal computed tomography scan showed a partial tumor response. This case emphasizes the importance of using trastuzumab in a patient with HER2-positive gastric hepatoid adenocarcinoma.

Magnetic resonance imaging (MRI) of six Yukatan minipig brains was performed. The animals were placed in stereotaxic conditions currently used in experiments. To allow for correctpositioning of the animal in the MRI instrument, landmarks were previously traced on the snout of the pig. To avoid movements, animal were anesthetized. The animals were placed in a prone position in a Siemens Magnetom Avanto 1.5 System with a head coil. Axial T2-weighted and sagittal T1-weighted MRI images were obtained from each pig. Afterwards, the brains of the pigs were fixed and cut into axial sections. Histologic and MR images were compared. The usefulness of this technique is discussed.
