The geriatric nutritional risk index (GNRI) is widely used for nutritional assessment in older inpatients and is associated with postoperative complications and cancer prognosis. We investigated the use of GNRI to predict long-term outcomes in hepatocellular carcinoma of all etiologies after hepatectomy. Overall, 346 patients were examined after propensity score matching. We dichotomized the GNRI score into high GNRI (> 98: N = 173) and low GNRI (≤ 98: N = 173) and evaluated recurrence-free survival (RFS) and overall survival (OS) between both groups. Clinicopathological characteristics between the low- and high-GNRI groups were similar after propensity score matching except for the components of the GNRI score (body mass index and serum albumin level), Child–Pugh score (comprising serum albumin level), and preoperative alpha-fetoprotein level (p < 0.0001, p < 0.0001, p = 0.0030, and p = 0.0007, respectively). High GNRI was associated with significantly better RFS and OS (p = 0.0003 and p = 0.0211, respectively; log-rank test). Multivariate analysis revealed that GNRI is an independent prognostic factor of RFS and OS (low vs. high; hazard ratio [HR], 1.8284; 95% confidence interval [CI] 1.3598–2.4586; p < 0.0001, and HR, 1.5452; 95% CI 1.0345–2.3079; p = 0.0335, respectively). GNRI is an objective, inexpensive, and easily calculated assessment tool for nutritional status and can predict prognosis of hepatocellular carcinoma after hepatectomy.

Disturbed colocalization of MRP2 and radixin was common in various cholestatic liver diseases, which may be associated with endocytic retrieval of MRP2 due to failure in anchoring MRP2 in the canalicular membrane.

Temporal lobe epilepsy is a common form of pharmacoresistant epilepsy, in which epileptogenic foci propagate to other regions of the brain from the area of the initial insult. The present study focused on epileptogenesis, that is, the development of the first foci inducing seizures in amygdala‐kindled mice, a model of temporal lobe epilepsy, to find the molecular process promoting the formation of epileptogenic networks. The expression of growth hormone (GH) was up‐regulated along neural circuits during the epileptogenesis, while there was no difference in the pituitary gland. The up‐regulation was associated with increased phosphorylation/activation of signal transducer and activator of transcription 5 and expression of the Serum Response Element‐regulated genes, FBJ osteosarcoma oncogene, early growth response 1, and Jun‐B oncogene, suggesting that expression of GH leads to GH signaling in the hippocampus and cortex. Furthermore, the administration of the hormone into the hippocampus markedly enhanced the progression of kindling. The administration of an inhibitor of its secretion into the hippocampus elicited a delay in the progression. Our results demonstrate directly that regulation via growth hormone has a robust impact in epileptogenesis.

Tumor location and immunity play important roles in the progression of colorectal cancer (CRC). This study aimed to investigate the differences in the immunosurveillance pattern between right‐ and left‐sided CRC and analyze their association with clinicopathologic features, including mismatch repair (MMR) status. We included surgically resected stage II/III CRC cases and evaluated the immunohistochemical findings of HLA class I, HLA class II, programmed cell death‐ligand 1 (PD‐L1), PD‐1, CTLA‐4, CD3, CD4, CD8, TIA‐1, T‐bet, GATA3, RORγT, Foxp3, and CD163. A total of 117 patients were included in the analyses; of these, 30 and 87 had right‐ and left‐sided cancer, respectively. Tumor immunity varied according to the tumor location in the overall cohort. Analysis of the tumors excluding those with DNA mismatch repair (MMR) deficiency also revealed that tumor immunity differed according to the tumor location. In right‐sided colon cancer (CC), high expression of Foxp3 (P = .0055) and TIA‐1 (P = .0396) were associated with significantly better disease‐free survival (DFS). High CD8 (P = .0808) and CD3 (P = .0863) expression tended to have better DFS. Furthermore, in left‐sided CRC, only high PD‐L1 expression in the stroma (P = .0426) was associated with better DFS. In multivariate analysis, high Foxp3 expression in right‐sided CC was an independent prognostic factor for DFS (hazard ratio, 7.6445; 95% confidence interval, 1.2091‐150.35; P = .0284). In conclusion, the immunosurveillance pattern differs between right‐ and left‐sided CRC, even after adjusting for MMR deficiency.

With the advent of advanced laparoscopic techniques in surgery, new applications have been found, which have expanded the role of laparoscopy in the gynecological field. The aim of this paper is to introduce our laparoscopic technique of taking a sigmoid colon autograft for colpopoiesis in a patient with congenital agenesis of the vagina. This technique is less invasive and is easy to perform, and it may be the best choice of operation in respect to the naturalness and the permanency of the vagina that results. The success of this laparoscopic technique of taking a sigmoid autograft for colpopoiesis suggests diverse possible applications in the future.
