Correlates of Injury-forced Work Reduction for Massage Therapists and Bodywork Practitioners.

BACKGROUND: Injury-forced work reduction (IFWR) has been acknowledged as an all-too-common occurrence for massage therapists and bodywork practitioners (M & Bs). However, little prior research has specifically investigated demographic, work attitude, and perceptual correlates of IFWR among M & Bs. PURPOSE: To test two hypotheses, H1 and H2. H1 is that the accumulated cost variables set ( e.g., accumulated costs, continuing education costs) will account for a significant amount of IFWR variance beyond control/demographic (e.g., social desirability response bias, gender, years in practice, highest education level) and work attitude/perception variables (e.g., job satisfaction, affective occupation commitment, occupation identification, limited occupation alternatives) sets. H2 is that the two exhaustion variables (i.e., physical exhaustion, work exhaustion) set will account for significant IFWR variance beyond control/demographic, work attitude/perception, and accumulated cost variables sets. RESEARCH DESIGN AND PARTICIPANTS: An online survey sample of 2,079 complete-data M & Bs was collected. Stepwise regression analysis was used to test the study hypotheses. The research design first controlled for control/demographic (Step1) and work attitude/perception variables sets (Step 2), before then testing for the successive incremental impact of two variable sets, accumulated costs (Step 3) and exhaustion variables (Step 4) for explaining IFWR. RESULTS: RESULTS SUPPORTED BOTH STUDY HYPOTHESES: accumulated cost variables set (H1) and exhaustion variables set (H2) each significantly explained IFWR after the control/demographic and work attitude/perception variables sets. The most important correlate for explaining IFWR was higher physical exhaustion, but work exhaustion was also significant. It is not just physical "wear and tear", but also "mental fatigue", that can lead to IFWR for M & Bs. Being female, having more years in practice, and having higher continuing education costs were also significant correlates of IFWR. CONCLUSIONS: Lower overall levels of work exhaustion, physical exhaustion, and IFWR were found in the present sample. However, since both types of exhaustion significantly and positively impact IFWR, taking sufficient time between massages and, if possible, varying one's massage technique to replenish one's physical and mental energy seem important. Failure to take required continuing education units, due to high costs, also increases risk for IFWR. Study limitations and future research issues are discussed.

Correlates of safety outcomes during patient ambulance transport: a partial test of the Haddon matrix.

The Haddon Matrix has been cited in a recent review of patient safety as a useful framework for understanding Emergency Medical Services (EMS) provider and patient injury prevention and safety during ambulance response and transport. The research goal of this study was to test part of the Haddon matrix, specifically variables within the pre-event host and event host cells, for explaining three multi-item ambulance-related safety outcomes: i.e., anticipated use of safety equipment, securing the patient, and securing the equipment. Complete study data were available for 648 EMS professionals who responded to the 2004 Longitudinal Emergency Medical Technician Attributes and Demographic Study (LEADS) survey. Overall very modest results were found. Specific findings indicated that EMS professionals with: lower perceived health, greater intrinsic satisfaction, more time in the patient compartment of an ambulance, and greater seatbelt use had higher anticipated use of ambulance safety equipment. For the patient being secured in an ambulance, the extremely high mean/low score variance resulted in only extrinsic satisfaction having a significant positive association. Finally, female EMS professionals, those more extrinsically satisfied, not being involved in a prior ambulance accident, and greater seatbelt use were related to higher frequency of securing ambulance equipment during patient transport.

Comparison of FoodChek E. coli test and AOAC Research Institute Performance Tested Method 010603 for detection of E. coli O157 in raw ground beef.

The FoodChek E. coli P157 assay [AOAC Research Institute (RI) Performance Tested Method (PTM) 060902] is a rapid detection system that incorporates the use of antibody-coated superparamagnetic nanoparticles in a lateral flow immunoassay format. The system comprises a commercially available enrichment medium, a magnetic nanoparticle immunoassay, and an automated reader for detection. Assay detection threshold is improved relative to traditional immunoassays through use of a magnetic nanoparticle label and a highly sensitive magnetic particle detector. FoodChek E. coli O157 is a reintroduction of the previously certified AOAC PTM 010603. The original assay was evaluated and approved in internal and independent laboratory studies. Vacci-Test Corp. has contracted with the original supplier of the PTM to remanufacture the test under identical conditions and with identical raw materials. This report is intended to show that FoodChek E. coli is identical in performance to the previously approved PTM. The results showed no difference for the parameters evaluated. Three kit lots along with three lots of media and media supplement were compared in lot-to-lot and stability testing. The results indicated no difference in performance across the three lots. The results showed sensitivity of > 99% and a specificity rate of > 98% for the FoodChek method and a significantly higher sensitivity than the reference method.

Laparoscopic colectomy for cancer is not inferior to open surgery based on 5-year data from the COST Study Group trial.

PURPOSE: Oncologic concerns from high wound recurrence rates prompted a multi-institutional randomized trial to test the hypothesis that disease-free and overall survival are equivalent, regardless of whether patients receive laparoscopic-assisted or open colectomy. METHODS: Eight hundred seventy-two patients with curable colon cancer were randomly assigned to undergo laparoscopic-assisted or open colectomy at 1 of 48 institutions by 1 of 66 credentialed surgeons. Patients were followed for 8 years, with 5-year data on 90% of patients. The primary end point was time to recurrence, tested using a noninferiority trial design. Secondary endpoints included overall survival and disease-free survival. (Kaplan-Meier) RESULTS: As of March 1, 2007, 170 patients have recurred and 252 have died. Patients have been followed a median of 7 years (range 5-10 years). Disease-free 5-year survival (Open 68.4%, Laparoscopic 69.2%, P=0.94) and overall 5-year survival (Open 74.6%, Laparoscopic 76.4%, P=0.93) are similar for the 2 groups. Overall recurrence rates were similar for the 2 groups (Open 21.8%, Laparoscopic 19.4%, P=0.25). These recurrences were distributed similarly between the 2 treatment groups. Sites of first recurrence were distributed similarly between the treatment arms (Open: wound 0.5%, liver 5.8%, lung 4.6%, other 8.4%; Laparoscopic: wound 0.9%, liver 5.5%, lung 4.6%, other 6.1%). CONCLUSION: Laparoscopic colectomy for curable colon cancer is not inferior to open surgery based on long-term oncologic endpoints from a prospective randomized trial.

Keeping up with evidence a new system for WHO's evidence-based family planning guidance.

The World Health Organization (WHO) is responsible for providing evidence-based family planning guidance for use worldwide. WHO currently has two such guidelines, Medical Eligibility Criteria for Contraceptive Use and Selected Practice Recommendations for Contraceptive Use, which are widely used globally and often incorporated into national family planning standards and guidelines. To ensure that these guidelines remain up-to-date, WHO, in collaboration with the Centers for Disease Control and Prevention and the Information and Knowledge for Optimal Health (INFO) Project at the Johns Hopkins Bloomberg School of Public Health's Center for Communication Programs, has developed the Continuous Identification of Research Evidence (CIRE) system to identify, synthesize, and evaluate new scientific evidence as it becomes available. The CIRE system identifies new evidence that is relevant to current WHO family planning recommendations through ongoing review of the input to the POPulation information onLINE (POPLINE) database. Using the Meta-Analysis of Observational Studies in Epidemiology guidelines and standardized abstract forms, systematic reviews are conducted, peer-reviewed, and sent to WHO for further action. Since the system began in October 2002, 90 relevant new articles have been identified, leading to 43 systematic reviews, which were used during the 2003-2004 revisions of WHO's family planning guidelines. The partnership developed to create and manage the CIRE system has pooled existing resources; scaled up the methodology for evaluating and synthesizing evidence, including a peer-review process; and provided WHO with finger-on-the-pulse capability to ensure that its family planning guidelines remain up-to-date and based on the best available evidence.

A comparison of laparoscopically assisted and open colectomy for colon cancer.

BACKGROUND: Minimally invasive, laparoscopically assisted surgery was first considered in 1990 for patients undergoing colectomy for cancer. Concern that this approach would compromise survival by failing to achieve a proper oncologic resection or adequate staging or by altering patterns of recurrence (based on frequent reports of tumor recurrences within surgical wounds) prompted a controlled trial evaluation. METHODS: We conducted a noninferiority trial at 48 institutions and randomly assigned 872 patients with adenocarcinoma of the colon to undergo open or laparoscopically assisted colectomy performed by credentialed surgeons. The median follow-up was 4.4 years. The primary end point was the time to tumor recurrence. RESULTS: At three years, the rates of recurrence were similar in the two groups--16 percent among patients in the group that underwent laparoscopically assisted surgery and 18 percent among patients in the open-colectomy group (two-sided P=0.32; hazard ratio for recurrence, 0.86; 95 percent confidence interval, 0.63 to 1.17). Recurrence rates in surgical wounds were less than 1 percent in both groups (P=0.50). The overall survival rate at three years was also very similar in the two groups (86 percent in the laparoscopic-surgery group and 85 percent in the open-colectomy group; P=0.51; hazard ratio for death in the laparoscopic-surgery group, 0.91; 95 percent confidence interval, 0.68 to 1.21), with no significant difference between groups in the time to recurrence or overall survival for patients with any stage of cancer. Perioperative recovery was faster in the laparoscopic-surgery group than in the open-colectomy group, as reflected by a shorter median hospital stay (five days vs. six days, P<0.001) and briefer use of parenteral narcotics (three days vs. four days, P<0.001) and oral analgesics (one day vs. two days, P=0.02). The rates of intraoperative complications, 30-day postoperative mortality, complications at discharge and 60 days, hospital readmission, and reoperation were very similar between groups. CONCLUSIONS: In this multi-institutional study, the rates of recurrent cancer were similar after laparoscopically assisted colectomy and open colectomy, suggesting that the laparoscopic approach is an acceptable alternative to open surgery for colon cancer.
