[Media treatment of messages on weight loss products by the Association for Public Health of Quebec and its reception].

BACKGROUND: The results of a study on weight loss products and services were released during a press conference organized by the Association pour la santé publique du Québec (ASPQ). The media widely covered this press conference. The purpose of this article is to answer the question: "How are messages emitted by public health institutions transmitted by the media and received by the population?" METHOD: The transcripts of the press conference, the press release as well as 43 documents from the print and broadcast media were evaluated according to a press analysis method. The analysis of these documents was based on the concept of the information unit. The compilation of these information units was used to produce charts which include data such as the frequency, partiality, weight tendency ("poids-tendance") and tendency-impact ("tendance-impact"). Furthermore, two focus groups of persons using weight loss products and services were conducted. RESULTS: In this article, we compare the emitted message with the one transmitted. The analysis of the message emitted by the ASPQ and that conveyed by the media revealed that for almost all subjects dealt with during the press conference, the media have been more partial than the ASPQ. The media not only expanded on the emitted message but also gave a negative image of weight loss products and services. Furthermore, the message transmitted by the media was very similar to the initial message. The focus groups on how the message was received by persons using weight loss products and services also revealed that the message was lost in the flow of information on weight loss products and services. CONCLUSION: This analysis of the emitted, transmitted and received messages has given us some indications on how to readjust the initial message and on what to emphasize in future press conferences.

Validation of 1997 Partin Tables' lymph node invasion predictions in men treated with radical prostatectomy in Montreal Quebec.

OBJECTIVE: The accuracy of 1997 Partin Tables' lymph node invasion (LNI) predictions exhibits important variability in different testing populations. We explored the LNI predictive accuracy in radical prostatectomy (RP) patients from Montreal, Canada. Moreover, we assessed the extent of change in predictive accuracy related to a modification of PSA coding from categorical to continuous. METHODS: We used pretreatment serum PSA, clinical stage, and biopsy Gleason sum from 537 men treated with RP to compare predicted and observed rates of LNI. Accuracy was quantified with receiver-operating characteristics curves. RESULTS: Accuracy was 0.760 in 369 evaluable patients, when categorically coded pretreatment PSA (0-4, 4.1-10, 10.1-20, 20.1+) was combined with clinical stage and biopsy Gleason sum. A 2.7% accuracy increase was noted when categorically coded PSA was replaced with continuously coded values. CONCLUSION: Partin Tables' LNI predictions showed comparable accuracy to a community-based sample from the United States (0.766), and to a recent, multi-institutional sample (0.740). However, accuracy was lower than reported in internal (0.818), and external (0.837) academic, validation cohorts. Accuracy of LNI predictions was appreciably higher, when continuously coded PSA was used.

[Problems and eradication of Ambrosia artemisiifolia L. in Quebec in the urban and suburban environments].

Ambrosia artemisiifolia is a common weed in Canada and it is one of the most important source of aero-allergenic pollen in the north-eastern part of North America. It is a problem mostly along roads in urban or suburban areas. It is easily controlled by herbicides but their use is increasingly restricted because of environmental considerations. Therefore, new methods must be developed to control this weed. Three types of controls were evaluated against Ambrosia artemisiifolia along an expressway in the summer of 1990. The control methods were hand weeding, mowing at 2 cm, 5 cm, or 8 cm, and crushing by a roadroller. These treatments were done at different dates in the course of the summer. Hand weeding was the most effective in reducing pollen and seed production although it was also the most expensive. Mowing was very effective when it was done at a height of 2 cm from the soil. It is the only height at which seed production was significantly reduced. Mowing efficacy in reducing pollen production tended to decrease with the raising of the mowing blade. The efficiency of weed pulling or moving improved when they were performed later in the growing season. Crushing was not an effective method of control. Mowing or hand weeding cannot eradicate Ambrosia artemisiifolia but if they are consistently used, they could reduce its population level over several years by decreasing seed production. The treatments either eliminated pollen production or reduced it at least by 88%, thereby insuring a relative relief for people allergic to the pollen of this plant.

[Portrait of the formation in vaccination training offered to Quebec nurses in the workplace].

INTRODUCTION: Nurses carry out essential functions in the area of immunization in Québec and their role has broadened considerably since January 2003, following legislative modifications. However, the training received may not always allow nurses to fill this role satisfactorily. This study seeks to document the training in immunization offered to Québec nurses in the workplace. METHOD: A questionnaire was mailed to the directors or heads of nursing care (DSI/RSI) in 477 health care establishments in Québec in March 2003. RESULTS: Health care establishments in Québec offer more training to nurses on the job (68%) than at the moment of hiring (43%). These percentages vary widely according to the type of establishment. More than 90% of the local community service centres (CLSC) that responded offer training to their nurses. The indications/contraindications of immunization products and emergencies related to vaccination represent the themes most frequently dealt with. Only 38% of respondents affirm that the nurses in their institution are "very favourable" to vaccination. DISCUSSION: Almost all Québec CLSCs, which is where most immunization activities are carried out, offer training in vaccination to their nurses. On the other hand, few hospital centres (CH) and long-term care establishments (CHSLD) do so. Further documentation should be carried out on the impact of less than optimal training on the promotion of immunization programs by nurses.
