Extracellular water to total body water ratio may mediate the association between phase angle and mortality in patients with cancer cachexia: A single-center, retrospective study.

Background & Aims: Recently, prognostic factors for cancer cachexia patients have been reported. We hypothesized that phase angle (PhA), which is measured by bioelectrical impedance analysis (BIA), might be a promising marker for assessing the nutritional status and prognosis of cancer patients. This study aimed to evaluate the predictive utility of PhA, which is mediated by several BIA factors and other anthropometric parameters, such as calf circumference, for the prognosis of cancer cachexia patients.

Multicentric prospective study of effect of dietary intake on quality of life for patients with end-stage cancers.

Objective: Impaired dietary intake (DI) contributes to deterioration of quality of life (QOL) in patients with end-stage diseases, including cancer, but the effects of DI on QOL specifically in terminal cancer has not been widely studied. Here, we evaluated the relationship between DI and QOL in patients with end-stage cancers.

Methods: We evaluated the energy amount of DI, performance status (PS) and QLQ-C15-PAL score of cancer patients with short prognoses in multicentre survey and analysed the parameters that influence QOL.

Preventing pancreatic fistula after distal pancreatectomy: An invagination method.

Following an increase in the use of the GIA stapler for treating a pancreatic stump, more techniques to prevent postoperative pancreatic juice leakage have been required. We describe one successful case using our new technique of invaginating the cut end of the pancreas into the stomach to prevent a pancreatic fistula (PF) from occurring. A 50-year-old woman with pancreatic cancer in the tail of the pancreas underwent distal pancreatectomy, causing a grade A PF.

Hepatic organoid formation in collagen sponge of cells isolated from human liver tissues.

We examined whether small hepatocytes (SHs), which are hepatic progenitor cells, could be isolated from a normal human liver and whether human hepatic cells could form hepatic organoids in a collagen sponge. Normal liver tissues were obtained from resected specimens from nine patients who underwent hepatic resection. Isolated hepatic cells were plated on dishes and a collagen sponge.

Absence of PERV infection in baboons after transgenic porcine liver perfusion.

Background: Xenotransplantation offers great promise to supplement the shortage of human organs available for transplant, but cross-species infection is a substantial concern. Porcine endogenous retrovirus (PERV), in particular, is thought to pose a risk as a potential pathogen to humans. We evaluated whether PERV is capable of infecting nonhuman primates in vivo after extracorporeal porcine liver perfusion (ECLP).

Bioartificial liver with whole blood perfusion.

In our series of studies, we have made an effort to develop a bioartificial liver (BAL) system through which whole blood can be perfused as in hemodialysis therapy. In this study, BAL cartridges containing porcine hepatocytes were prepared and perfused in an extracapillary space with human whole blood in vitro. Lidocaine loading tests were performed to evaluate the detoxification ability of the BAL.

Suppressed complement activation in human decay accelerating factor transgenic porcine liver cross-circulated with nonhuman primates.

Background: We developed an extracorporeal liver perfusion (ECLP) system as a liver-assist device. In this study, we evaluated the safety of the ECLP using human decay accelerating factor (hDAF) transgenic porcine livers in healthy baboons.

Methods: Livers were isolated from five hDAF transgenic pigs and five nontransgenic pigs for the ECLP.

Long-term culture of primary human hepatocytes with preservation of proliferative capacity and differentiated functions.

Background: The aim of this study was to develop a suitable method for the prolonged culture and maintenance of human hepatocytes with preservation of both proliferative capacity and differentiated functions.

Materials And Methods: Primary human hepatocytes were isolated from small pieces of liver tissue obtained from 15 patients who underwent hepatic resection. Hepatocytes were cultured in keratinocyte-stimulating factor medium supplemented with 10% human serum, 10 mM nicotinamide, 10 ng/ml epidermal growth factor, 0.
