Effect of LZSA Glass-Ceramic Addition on Pressureless Sintered Alumina. Part II: Mechanical Behavior
Chemo-protective effect of aqueous extract of the resurrection plant Selaginella involvens (Sw.) Spring on UV-tolerance during spore germination of Pteris argyraea T. Moore
The present study was aimed to know the effect of aqueous extracts of the resurrection plant, Selaginella involvens (Sw.) Spring on spore germination in Pteris argyraea T. Moore and also to know the ameliorating effect of the extracts on UV-Stress during spore germination of Pteris argyraea T. Moore. Based on the present study it is concluded that the extract of Selaginella involvens, shows growth promoting effect by enhancing the spore germination in Pteris argyraea. Both UV and aqueous extracts of Selaginella involvens enhances germination, but the UV stress results in both physical and morphogenetic abnormalities. It is to be noted that in the extract treated spores, the physical abnormalities are in less frequency when compared to the extract- untreated spores
Factors Driving Readmissions in Tibia and Femur Fractures
As the American healthcare system shifts towards bundled payments, readmissions will become a measure of healthcare quality. The purpose of this study was to characterize readmission trends and factors influencing readmission in patients with diaphyseal femur and tibia fractures. Through a retrospective chart review, all patients who presented to a level 1 trauma center from 2004 to 2006 were evaluated. By using current procedural terminology codes, 1,040 patients with diaphyseal tibia or femur fractures fixed by IMN were identified. 645 patients were included for analysis. 30-day, 60-day, and 90-day readmission rates were compared with fracture type, reason for readmission, and basic demographic information. The 60-day readmission rate for open tibia fractures (14.8%) was significantly higher than the 60-day readmission rate for closed tibia fractures (8.0%) (p=0.037). When comparing reasons for 60-day readmissions, 50% of closed fractures were readmitted due to infection, while the other 50% needed additional surgery. 91.7% of open fractures readmitted in 60 days were due to infection. In a bundled payment system, orthopedic trauma must gain insight into drivers of readmission to identify those at risk for readmission and design effective healthcare plans for these patients
School-based violence prevention strategy: a pilot evaluation
Abstract:
Background: Violence has recently been reported among a primarily young, minority population in Nashville, Tennessee. School-based programs have been proven as effective
methods of reducing violent behavior, beliefs, and actions that lead to violence among adolescents.
Methods: Investigators implemented a rigorous search for an appropriate school-based violence prevention program for Metropolitan Nashville middle school students utilizing a
systematic review and discussion group with victims of violence. 27 programs nation-wide were reviewed and 2 discussion groups with African American males under the age of 25 admitted to a
level 1 trauma center for assault-related injuries were conducted. Our findings led to a single, evidence-based conflict resolution program. In conjunction with educators, we evaluated the
program’s effectiveness in a pilot study in a Nashville middle school with high rates of violence.
Results: 122 students completed the conflict resolution program and described their behavior and experiences with violence in a pre-test/post-test self-rate questionnaire. Results showed a
significant decrease in violent behavior and an increase in students’ competencies to deal with violence (p less than 0.05).
Conclusions: This study shows that a reduction in violent behavior and beliefs among middle school students can be achieved through the implementation of a targeted violence intervention
program. A larger-scale intervention is needed to develop more conclusive evidence of
effectiveness
Do orthopaedic trauma patients develop higher rates of cardiac complications? An analysis of 56,000 patients
The Costs of Operative Complications for Ankle Fractures: A Case Control Study
As our healthcare system moves towards bundling payments, it is vital to understand the potential financial implications associated with treatment of surgical complications. Considering that surgical treatment of ankle fractures is common, there remains minimal data relating costs to postsurgical intervention. We aimed to identify costs associated with ankle fracture complications through case-control analysis. Using retrospective analysis at a level I trauma center, 28 patients with isolated ankle fractures who developed complications (cases) were matched with 28 isolated ankle fracture patients without complications (controls) based on ASA score, age, surgery type, and fracture type. Patient charts were reviewed for demographics and complications leading to readmission/reoperation and costs were obtained from the financial department. Wilcoxon tests measured differences in the costs between the cases and controls. 28 out of 439 patients (6.4%) developed complications. Length of stay and median costs were significantly higher for cases than controls. Specifically, differences in total costs existed for infection and hardware-related pain. This is the first study to highlight the considerable costs associated with the treatment of complications due to isolated ankle fractures. Physicians must therefore emphasize methods to control surgical and nonsurgical factors that may impact postoperative complications, especially under a global payment system
