Background: During esophagectomy, laparoscopy can be used together with thoracoscopy, but it is not known whether a combined thoracoscopic-laparoscopic procedure is associated with fewer postoperative complications than open esophagectomy, and without compromising oncological outcome.
Methods: This was a longitudinal cohort study that included 185 esophageal cancer patients, including 72 who underwent combined thoracoscopic-laparoscopic esophagectomy (TLE), 34 who underwent thoracoscopic esophagectomy (TE), and 79 who underwent open esophagectomy (OE) between January 2002 and May 2010. The main outcome measures were postoperative respiratory and overall complications. The secondary outcome was 2-year relapse-free survival (RFS).
Results: Respiratory complications occurred in 9 patients who underwent TLE, 13 who underwent TE, and 31 who underwent OE. TLE was associated with fewer respiratory complications (TLE vs. OE: odds ratio [OR], 0.22; 95% confidence interval [CI], 0.09-0.53 and TE vs. OE: OR, 0.71; 95% CI 0.29-1.76). Overall complications occurred in 34 patients who underwent TLE, 20 who underwent TE, and 54 who underwent OE. TLE was associated with fewer overall complications (TLE vs. OE: OR, 0.47; 95% CI 0.23-0.94 and TE vs. OE: OR, 0.51; 95% CI 0.21-1.25). The 2-year RFS rates were similar among the three groups: 71.6% for TLE, 57.7% for TE, and 58.3% for OE (TLE vs. OE: hazard ratio, 0.65; 95% CI 0.35-1.20 and TE vs. OE: hazard ratio, 0.91; 95% CI 0.45-1.82).
Conclusion: Unlike TE, TLE was associated with fewer postoperative complications than was OE, with no compromise of 2-year RFS. A randomized controlled trial with longer follow-up is needed.

Age-related differences in eye movements and the association with Archimedes spiral tracing performance in young and older adults.

Age-related hand motor impairments may critically depend on visual information though few studies have examined eye movements during tasks of hand function in older adults. The purpose of this study was to assess eye movements and their association with performance while tracing on a touchscreen in young and older adults. Eye movements of 21 young (age 20-38 years; 12 females, 9 males) and 20 older (65-85 years; 10 females, 10 males) adults were recorded while performing an Archimedes spiral tracing task, a common clinical assessment sensitive to age-associated impairments in hand function.

Introduction: Interpersonal theory can be used to better understand the personal and social manifestations of individual difference variables in physician assistant (PA) students. Emotional intelligence (EI) is characterized by self and social awareness that facilitates effective communication. While EI has been examined in PA students, a theoretical framework for describing why and how EI has beneficial effects has not been articulated.

Characteristics associated with individuals who frequent the emergency department at higher rates have been well established; however, factors associated with greater emergency department visits following a recent sexual assault are largely unknown. The current study evaluated the associations between pre-assault factors such as substance use and physical injuries, assault characteristics such as genital injury, non-genital injury, alcohol or drug use involvement, intimate partner involvement, and emergency department visits one-year after a sexual assault medical forensic exam (SAMFE). The current study included a medical record review of 123 individuals who received a SAMFE at a hospital in the United States.

It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.
Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.
