Patient-reported outcomes 6Â months after enhanced recovery after colorectal surgery.
BackgroundEnhanced recovery after surgery (ERAS) programs have been established as perioperative strategies associated with improved outcomes. However, intermediate and long-term patient-reported outcome data for patients undergoing ERAS interventions remain limited. We utilized an automated telephone survey 6 months post-colorectal surgery from patients who participated in an ERAS program to determine 6-month patient-reported outcomes and associated predictive factors.MethodsWe conducted a prospective observational study, using an automated telephone survey and researcher-administered telephone questionnaire 6 months after patients underwent abdominal colorectal surgery. Six-month significant outcomes were defined by persistent pain, hospital readmission, and patient satisfaction. Patients reporting these outcome variables were compared with patients who met none of these criteria. Additionally, analysis was performed to determine differences between patients that did and did not respond to the 6-month survey. A chi-square test was used to determine any relationship for categorical variables, a two independent sample t test for length of procedure/stay, and a Wilcoxon-Mann-Whitney test for pain scores.ResultsOne hundred fifty-four of 324 patients contacted 6 months after surgery completed the automated telephone survey (47.53%). There was no statistical difference between patient populations completing and not completing the survey. Hospital 6-month readmission was associated with patients with a diagnosis of cancer (P = .049) and with a longer mean length of index procedure (282 vs. 206 minutes, P = .006). Median 6-month pain scores were higher for patients that underwent an open procedure compared to laparoscopic (Z = - 2.06, P = .04).ConclusionsLong-term benefits of an ERAS program were mostly confirmed. Longer procedure time and patients with cancer correlated with an increased likelihood of hospital 6-month readmission, suggesting that perioperative outcomes in complex cancer patients need to be evaluated over a longer time frame. In addition, invasiveness of procedure continues to have a significant effect on pain scores even 6 months later
Doping evoluton of antiferromagnetic order and structural distortion in LaFeAsOF
We use neutron scattering to study the structural distortion and
antiferromagnetic (AFM) order in LaFeAsOF as the system is doped
with fluorine (F) to induce superconductivity. In the undoped state, LaFeAsO
exhibits a structural distortion, changing the symmetry from tetragonal (space
group ) to orthorhombic (space group ) at 155 K, and then
followed by an AFM order at 137 K. Doping the system with F gradually decreases
the structural distortion temperature, but suppresses the long range AFM order
before the emergence of superconductivity. Therefore, while superconductivity
in these Fe oxypnictides can survive in either the tetragonal or the
orthorhombic crystal structure, it competes directly with static AFM order.Comment: reference update
Threshold Anonymous Announcement in VANETs.
Vehicular ad hoc networks (VANETs) allow wireless communications between vehicles without the aid of a central server. Reliable exchanges of information about road and traffic conditions allow a safer and more comfortable travelling environment. However, such profusion of information may allow unscrupulous parties to violate user privacy. On the other hand, a degree of auditability is desired for law enforcement and maintenance purposes. In this paper we propose a Threshold Anonymous Announcement service using direct anonymous attestation and one-time anonymous authentication to simultaneously achieve the seemingly contradictory goals of reliability, privacy and auditability
Spin gap and magnetic resonance in superconducting BaFeNiAs
We use neutron spectroscopy to determine the nature of the magnetic
excitations in superconducting BaFeNiAs ( K).
Above the excitations are gapless and centered at the commensurate
antiferromagnetic wave vector of the parent compound, while the intensity
exhibits a sinusoidal modulation along the c-axis. As the superconducting state
is entered a spin gap gradually opens, whose magnitude tracks the
-dependence of the superconducting gap observed by angle resolved
photoemission. Both the spin gap and magnetic resonance energies are
temperature \textit{and} wave vector dependent, but their ratio is the same
within uncertainties. These results suggest that the spin resonance is a
singlet-triplet excitation related to electron pairing and superconductivity.Comment: 4 pages, 4 figure
The Effect of Textiles on Perceived Physiological Comfort While Backpacking in the Cold
Clothing is the primary means that wilderness backpackers have to protect themselves from illnesses and injuries that can occur while hiking in the cold. Currently, backpackers are recommended to dress in clothing layers; however, when hiking in the cold, this system may not meet backpackers’ simultaneous, yet conflicting needs for thermal insulation and heat dissipation
