External validation of the Japanese difficulty score for laparoscopic hepatectomy in patients undergoing robotic-assisted hepatectomy.

Introduction: The Japanese difficulty score (JDS) categorizes laparoscopic hepatectomy into low, intermediate, and high complexity procedures, and correlates with operative and postoperative outcomes. We sought to perform a validation study to determine if the JDS correlates with operative and postoperative indicators of surgical complexity for patients undergoing robotic-assisted hepatectomy.

Methods: Retrospective review of 657 minimally invasive hepatectomy procedures was performed between January 2008 through March 2019.

Future liver remnant augmentation preceding ex vivo hepatectomy with IVC replacement: a strategy to achieve R0 margins.

Purpose: Ex vivo hepatectomy with autotransplantation (EHAT) provides opportunity for R0 resection. As EHAT outcomes after future liver remnant (FLR) augmentation techniques are not well documented, we examine results of EHAT after augmentation for malignant tumors.

Methods: Retrospective analysis of six cases of EHAT was performed.

Irreversible Electroporation-Assisted Resection for Locally Advanced Pancreas Cancer.

Background: A significant number of patients with advanced pancreatic cancer are unable to undergo resection due to vascular involvement. Irreversible electroporation (IRE) has shown promise in improving survival. This study sought to assess a novel IRE application whereby IRE was performed pre-resection to alter tissue plasticity and assist tumor removal from underlying vasculature when surgical excision was otherwise precluded.

New tests to measure individual differences in matching and labelling facial expressions of emotion, and their association with ability to recognise vocal emotions and facial identity.

Although good tests are available for diagnosing clinical impairments in face expression processing, there is a lack of strong tests for assessing "individual differences"--that is, differences in ability between individuals within the typical, nonclinical, range. Here, we develop two new tests, one for expression perception (an odd-man-out matching task in which participants select which one of three faces displays a different expression) and one additionally requiring explicit identification of the emotion (a labelling task in which participants select one of six verbal labels). We demonstrate validity (careful check of individual items, large inversion effects, independence from nonverbal IQ, convergent validity with a previous labelling task), reliability (Cronbach's alphas of.

Individual differences in the ability to recognise facial identity are associated with social anxiety.

Previous research has been concerned with the relationship between social anxiety and the recognition of face expression but the question of whether there is a relationship between social anxiety and the recognition of face identity has been neglected. Here, we report the first evidence that social anxiety is associated with recognition of face identity, across the population range of individual differences in recognition abilities. Results showed poorer face identity recognition (on the Cambridge Face Memory Test) was correlated with a small but significant increase in social anxiety (Social Interaction Anxiety Scale) but not general anxiety (State-Trait Anxiety Inventory).

Face ethnicity and measurement reliability affect face recognition performance in developmental prosopagnosia: evidence from the Cambridge Face Memory Test-Australian.

The Cambridge Face Memory Test (CFMT, Duchaine & Nakayama, 2006) provides a validated format for testing novel face learning and has been a crucial instrument in the diagnosis of developmental prosopagnosia. Yet, some individuals who report everyday face recognition symptoms consistent with prosopagnosia, and are impaired on famous face tasks, perform normally on the CFMT. Possible reasons include measurement error, CFMT assessment of memory only at short delays, and a face set whose ethnicity is matched to only some Caucasian groups.

An in vitro comparison of the antimicrobial effects of various endodontic medicaments on Enterococcus faecalis.

The purpose of this in vitro study was to investigate the antimicrobial action of Dermacyn (Oculus Innovative Sciences, Petaluma, CA), BioPure MTAD (Dentsply Tulsa Dental, Johnson City, TN), 2% chlorhexidine (CHX; Ultradent, West Jordan, UT), and 5.25% sodium hypochlorite (NaOCl) against Enterococcus faecalis (American Type Culture Collection 4082). Eighteen Petri dishes of BHI agar were inoculated with E faecalis.
