BACKGROUND: Oxytocin is routinely used as prophylaxis against uterine atony. During elective cesarean delivery (CD), an oxytocin bolus is used to initiate adequate uterine tone, followed by an oxytocin infusion to maintain uterine contractility. However, it is unclear whether oxytocin maintenance infusion rate influences total estimated blood loss (EBL). METHODS: We performed a prospective, randomized, double-blind trial in 51 women undergoing elective CD. Women were randomly assigned to receive an oxytocin maintenance infusion of 2...

There is a national trend to refer patients requiring complex oncologic surgery to tertiary high-volume cancer centers. However, this presents major access challenges to Hawai'i patients seeking care. The purpose of this study is to demonstrate that complex oncologic surgery can be safely performed at community hospitals like those in Hawai'i. From July 2007 to December 2014, 136 patients underwent complex oncologic procedures at a community hospital in Hawai'i by a single general surgeon. Cases included esophagogastric, hepatobiliary, pancreatic, rectal, and retroperitoneal resections...

Functional connectivity (FC) analysis with data collected as continuous tasks and activation analysis using data from block-design paradigms are two main methods to investigate the task-induced brain activation. If the concatenated data of task blocks extracted from the block-design paradigm could provide equivalent FC information to that derived from continuous task data, it would shorten the data collection time and simplify experimental procedures, and the already collected data of block-design paradigms could be reanalyzed from the perspective of FC...
