Long-term survival of cemented distal femoral endoprostheses with a hydroxyapatite-coated collar: a histological study and a radiographic follow-up.

Abstract: Background: The objective of this study was to examine the degree of osteointegration into a hydroxyapatite-coated collar and relate this finding to aseptic loosening in patients with a distal femoral replacement used to treat primary bone cancer. Our hypothesis was that the implant collar would increase osteointegration and reduce the rate of aseptic implant loosening. Methods: Sixty-one patients treated with a primary cemented distal femoral prosthesis between 1992 and 2001 were included in this study. The mean duration of follow-up was 8.5 years (range, two to eighteen years). Extracortical bone growth into the grooved hydroxyapatite-coated collar was quantified radiographically. Histological sections through four hydroxyapatite-coated collars and four implants with no collar, retrieved following amputation due to local recurrence or at autopsy at a mean of 3.5 years (range, 1.4 to 6.1 years) after implantation, were evaluated as well. Results: Five (8%) of the implants were revised because of aseptic loosening, 3% of the implants fractured, and 3% were revised because of infection. Six limbs (10%) required amputation because of local tumor recurrence. On radiographs, osteointegration into the collar was seen to have occurred in 70% of the patients and did not correlate with sex, age, diagnosis, or length of time postoperatively. Histological analysis showed mature lamellar bone within the grooves of the hydroxyapatite-coated collar, and bone was observed in direct contact with the hydroxyapatite coating. Extracortical bone failed to make direct contact with the surface of the implants manufactured without a collar. Conclusions: The use of cemented distal femoral massive bone tumor prostheses with a hydroxyapatite-coated collar located at the shoulder of the implant was followed by a low (8%) rate of revision due to aseptic loosening. The use of hydroxyapatite grooved collars may lead to osteointegration of the implant shoulder (collar) and may reduce the rate of aseptic loosening. Level of Evidence: Therapeutic Level IV.

Counterproductive behavior at work: A comparison of blue collar and white collar workers

Abstract: Counterproductive behavior at workplace has emerged as a major area of concern for researchers, theorists and managers in organizations due to its heavy cost and disruptive nature. Every organization thus endeavors to limit the effects and pervasiveness of these detrimental behaviors. This research investigates the magnitude of counterproductive work behaviors in a group of 400 blue collar and white collar workers. Three selfreported instruments used in this study are, Minnesota Job Satisfaction Scale, the Interpersonal Conflict Scale (ICAW) and the Counterproductive Work Behavior Checklist (CWB-C). Results are deduced by applying several techniques of descriptive and inferential statistics such as mean rank analysis, independent samples t-test, Pearson correlation and regression. Results show that a statistically significant difference exists in the magnitude of counterproductive work behaviors (CWBs) in blue and white collar workers. A high degree of job satisfaction and minimal degrees of interpersonal conflicts and counterproductive work behaviors are found in white collar workers. While, low level of job satisfaction and high degrees of interpersonal conflicts and counterproductive work behaviors are reported in blue collar workers. The results of the study also bring forward the predictability of CWB on the basis of the magnitude of interpersonal conflicts and job satisfaction. It is concluded that the job satisfaction has a diminishing effect on counterproductive behaviors.

Assessing the safety of collars used to attach predation deterrent devices and ID tags to pet cats

Abstract: Collar-worn deterrents reduce predation by cats while collar-mounted ID enhances return of lost animals. A perception that collars are hazardous limits their use. We defined cases as 'collar incidents' (cat snagged its collar or caught a paw), 'collar injuries' (veterinary treatment needed for a collar incident), and 'collar deaths' (cat died), before integrating data from veterinarians, owners from the general public and owners from a welfare society. Despite biases associated with each of these groups, taken together, the results from these indicated that collar injuries or deaths are rare. Interviews with one hundred and seven veterinarians indicated an average rate of one collar injury observed per 2.3 years of veterinary practice. At one practice, over three years, only 0.33% of 4,460 cat cases were collar injuries, while 180 cat cases at four clinics during August and November 2011 included none. The 63 owners from the general public reported only one collar injury and no deaths in a lifetime of ownership, although 27% experienced collar incidents. In contrast, 22% reported cats needing treatment following road accidents, 53% reported cats needing treatment for fighting injuries and 62% had owned cats killed on the road. Most (62%) of the 55 respondents from a cat welfare society had experienced a collar incident, but only two cats needed treatment. One died. In contrast, 31 and 58% reported cats needing treatment for road accidents and fighting, respectively, and 41% had owned cats killed on the road. Fighting and road accidents are greater hazards to roaming cats than collars, which offer the compensatory benefits of mounting predation deterrents and ID tags.

Electronically-actuated cementing port collar

Abstract: A cementing port collar has an opening sleeve biased from a closed position to an opened position relative to the collar's exit port, and a first restraint temporarily holds the opening sleeve closed. The collar also has a closing sleeve biased from an opened position to a closed position, and a second restraint temporarily holds the closing sleeve opened. During cementing, the first restraint is electronically activated with a first trigger to release the opening sleeve opened so cement slurry can pass out of the collar's exit port to the borehole annulus. When cementing is completed, the second restraint is electronically activated with a second trigger to release the closing sleeve closed to close off the collar to the borehole so the cement can set. The restraints can include bands of synthetic fiber, which are burned by fuses activated by a controller of the collar responding to passage of RFID tags.

Method for detecting fighting behaviors

Abstract: The invention provides a method for detecting a fighting behavior. The method comprises the following steps of detecting a human body contour and a collar contour in each frame image; when determining that the distance between any two human body contours is less than a first threshold value, respectively detecting the position relation between the collar and the head of each person in the image; and when the change of the position relation between the collar and the head of one person is more than the threshold value, determining that the fighting behavior occurs. A fighting process is determined through the distance between any two human body contours and the position relation between the collar and the head of a human body without detecting by the eyes of a user, so that the phenomenon that the fighting behavior cannot be timely found is avoided.
