    The feline AB blood group system has clinical significance because type B cats have natural alloimmune anti-A antibodies which can cause isoerythrolysis of the newborn and life-threatening transfusion reactions. In the United States, the prevalence of type B blood is estimated to be 1% to 2%. This study determined the prevalence of feline AB blood groups among 207 potential blood donor cats that included 178 domestic cats, in the Montreal area of Quebec, Canada. Blood typing was performed using a standardized tube technique. Blood types AB and B were confirmed using a backtyping technique. The frequency of blood types among the studied population was as follows: 95.2% type A, 4.4% type B, and 0.48% type AB. Among domestic cats, the frequency was 94.4% for type A, 5% for type B, and 0.6% for type AB. The frequency of type B was higher than expected, which reinforces the recommendation to ensure blood compatibility of the recipient and donor before transfusion through typing and possibly cross-matching as well.

    Gaucher disease, the most prevalent lysosomal storage disease, is an autosomal recessive sphingolipidosis resulting from deficient glucocerebrosidase activity. Genomic DNA of the structural gene of glucocerebrosidase from normal individuals and fifteen unrelated patients with the three clinical forms of Gaucher disease from the Montreal/Quebec region were amplified by the polymerase chain reaction technique. Allele-specific oligonucleotide dot blot hybridization and restriction fragment length polymorphism were used to screen for five of the mutations [mutations 120, 370, 415, 444 (Nci), and 463] in exons 5, 9, and 10 of glucocerebrosidase gene. It was noted that all of the patients had at least one of the known mutant alleles. However, 9 patients (9/15 = 60%) had an unknown allele. Mutation 370 in exon 9 was present in the heteroallelic form in eight out of the nine patients with type 1 Gaucher disease, but was present in none of the six patients with type 2 or type 3 Gaucher disease. The Nci mutation in exon 10 was present in the heteroallelic form in three patients with type 1 Gaucher disease and in either the heteroallelic or homoallelic form in all of the six patients with type 2 or type 3 Gaucher disease. The 415/Nci mutations were found in a mildly affected 29-year-old patient with type 1 Gaucher disease, as well as in an infant with the type 2 form. These findings demonstrate the clinical and molecular genetic heterogeneities of Gaucher disease, the presence of unknown Gaucher allele(s) in most (60%) of the patients surveyed, and the occasional inexplicable lack of phenotype-genotype correlation among some patients.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1776640

    Objectives. We examined associations between residential exposure to BIXI (BIcycle-taXI)—a public bicycle share program implemented in Montreal, Quebec, in 2009, which increases accessibility to cycling by making available 5050 bicycles at 405 bicycle docking stations—and likelihood of cycling (BIXI and non-BIXI) in Montreal over the first 2 years of implementation. Methods. Three population-based samples of adults participated in telephone surveys. Data collection occurred at the launch of the program (spring 2009), and at the end of the first (fall 2009) and second (fall 2010) seasons of implementation. Difference in differences models assessed whether greater cycling was observed for those exposed to BIXI compared with those not exposed at each time point. Results. We observed a greater likelihood of cycling for those exposed to the public bicycle share program after the second season of implementation (odds ratio = 2.86; 95% confidence interval = 1.85, 4.42) after we controlled for weather, built environment, and individual variables. Conclusions. The implementation of a public bicycle share program can lead to greater likelihood of cycling among persons living in areas where bicycles are made available. PMID:23327280

    A population-based case-control study of the associations between various cancers and occupational exposures was carried out in Montreal, Quebec, Canada. Between 1979 and 1986, 484 persons with pathologically confirmed cases of bladder cancer and 1,879 controls with cancers at other sites were interviewed, as was a series of 533 population controls. The job histories of these subjects were evaluated by a team of chemist/hygienists for evidence of exposure to a list of 294 workplace chemicals, and information on relevant non-occupational confounders was obtained. On the basis of results of preliminary analyses and literature review, 19 occupations, 11 industries, and 23 substances were selected for in-depth multivariate analysis. Logistic regression analyses were carried out to estimate the odds ratio between each of these occupational circumstances and bladder cancer. There was weak evidence that the following substances may be risk factors for bladder cancer: natural gas combustion products, aromatic amines, cadmium compounds, photographic products, acrylic fibers, polyethylene, titanium dioxide, and chlorine. Among the substances evaluated which showed no evidence of an association were benzo(a)pyrene, leather dust, and formaldehyde. Several occupations and industries were associated with bladder cancer, including motor vehicle drivers and textile dyers. PMID:7998589

    This study used a contingent choice method to determine the economic value of improving various ecosystem services (ESs) of the Blue Network of Greater Montreal (Quebec, Canada). Three real projects were used and the evaluation focused on six ESs that are related to freshwater aquatic ecosystems: biodiversity, water quality, carbon sequestration, recreational activities, landscape aesthetics and education services. We also estimated the value associated with the superficies of restored sites. We calculated the monetary value that a household would be willing to pay for each additional qualitative or quantitative unit of different ESs, and these marginal values range from $0.11 to $15.39 per household per unit. Thus, under certain assumptions, we determined the monetary values that all Quebec households would allocate to improve each ES in Greater Montreal by one unit. The most valued ES was water quality ($13.5 million), followed by education services ($10.7 million), recreational activities ($8.9 million), landscape aesthetics ($4.1 million), biodiversity ($1.2 million), and carbon sequestration ($0.1 million). Our results ascribe monetary values to improved (or degraded) aquatic ecosystems in the Blue Network of Greater Montreal, but can also enhance economic analyses of various aquatic ecosystem restoration and management projects.

  16. A fluid inclusion study of vug minerals in dawsonite-altered phonolite sills, Montreal, Quebec: implications for HFSE mobility

    1993-03-01

    Ordovician limestones in the Francon quarr on the island of Montreal, Quebec, are host to three sills of Cretaceous age composed of phonolite that has been extensively altered to dawsonite. An interesting feature of the sills is the presence of abundant vugs containing a wide variety of minerals, including several in which one or more high field strength elements (Zr, Hf, Nb, Ti) is a major component. The most important of these latter minerals is weloganite, a rare strontium zirconium hydrous carbonate, first identified in the Francon, quarry. Four types of inclusions have been recognized in vug minerals: aqueous, aqueous-carbonic, carbonic and solidbearing. Aqueous inclusions homogenize at temperatures mainly between 70° and 170°C and between 230° and 390°C. The homogenization temperatures of primary inclusions cluster around 350°C. Aqueous inclusions and the aqueous phase in aqueous-carbonic inclusions have salinities ranging between 10 and 24 eq.wt.% NaCl equivalent. Primary aqueous-carbonic inclusions have low XCO2 (<0.03), whereas secondary aqueous-carbonic inclusions can have high XCO2 (>0.7); carbonic inclusions are all secondary. Nahcolite, dawsonite and weloganite occur as daughter minerals or trapped solids. Nahcolite and possibly natron or mirabilite appear to form in frozen inclusions. Analyses of fluid inclusion decrepitates detected high concentrations of Na, Cl, Al, S, and C. The extraordinarily high concentration of Al in the fluid (possibly exceeding 1 wt.%) suggests a pH of approximately 10. Pressure and temperature conditions, estimated from stratigraphic reconstruction and the isochores of primary aqueous fluid inclusions, were 450 bar and 360 to 400°C, respectively. The relatively high temperatures and compositions of primary fluid inclusions suggest that vug filling was the result of mineral precipitation from an orthomagmatic fluid. A model is proposed in which a partially crystallized phonolite melt started exsolving a homogeneous low

    BACKGROUND: Little attention has been devoted to the effects on children’s respiratory health of exposure to sulphur dioxide (SO2) in ambient air from local industrial emissions. Most studies on the effects of SO2 have assessed its impact as part of the regional ambient air pollutant mix. OBJECTIVE: To examine the association between exposure to stack emissions of SO2 from petroleum refineries located in Montreal’s (Quebec) east-end industrial complex and the prevalence of active asthma and poor asthma control among children living nearby. METHODS: The present cross-sectional study used data from a respiratory health survey of Montreal children six months to 12 years of age conducted in 2006. Of 7964 eligible households that completed the survey, 842 children between six months and 12 years of age lived in an area impacted by refinery emissions. Ambient SO2 exposure levels were estimated using dispersion modelling. Log-binomial regression models were used to estimate crude and adjusted prevalence ratios (PRs) and 95% CIs for the association between yearly school and residential SO2 exposure estimates and asthma outcomes. Adjustments were made for child’s age, sex, parental history of atopy and tobacco smoke exposure at home. RESULTS: The adjusted PR for the association between active asthma and SO2 levels was 1.14 (95% CI 0.94 to 1.39) per interquartile range increase in modelled annual SO2. The effect on poor asthma control was greater (PR=1.39 per interquartile range increase in modelled SO2 [95% CI 1.00 to 1.94]). CONCLUSIONS: Results of the present study suggest a relationship between exposure to refinery stack emissions of SO2 and the prevalence of active and poor asthma control in children who live and attend school in proximity to refineries.

    Objective We conducted a chart review to identify postsecondary students and nonstudents in the same age range who presented to the emergency department following a suicide attempt to (1) compare demographic characteristics and suicide risk factors and (2) determine factors associated with more serious attempts requiring hospitalizations. Method The study was conducted in 1 tertiary trauma hospital and 1 community hospital affiliated with McGill University, Montreal, Quebec, Canada, between January 1, 2009, and March 31, 2010. Charts of patients with potential suicide attempts were identified from medical records using ICD-10 codes that indicated traumatic injury, intentional self-harm, poisoning, and psychiatric or perception/cognition disorders and from the emergency department triage file using keywords that indicated suicidality or self-harm at presentation. Results In multivariable logistic regression models (odds ratio, 95% CI), students were younger (per 5-year increase: 0.22, 0.12–0.41), less likely to be born in Canada (0.17, 0.06–0.44), and more likely to use less violent methods (laceration, poisoning, other, multiple methods) versus more violent methods (collision, jump, fire burns, firearm, hanging) in their attempt. Fewer students had a history of substance abuse (0.12, 0.02–0.94) but were not different from nonstudents on history of other mental disorders. Less students attempted suicide in the winter/spring (January–April) versus fall (September–December) semester (0.32, 0.11–0.91). Students who attempted suicide were more likely to have family/social support. Those who attempted suicide in the previous year were more likely to require hospitalization for their current suicide attempt. Conclusions Knowledge of specific factors associated with suicide attempts in young people can help inform and guide suicide prevention efforts in both academic and community settings.

    A two-way television network using the Canadian satellite ANIK-B was utilized to transmit radiographic images from Northern Quebec to Montreal. The accuracy of the radiologist's interpretation and his satisfaction with the TV system were studied using a series of 67 preselected cases and 425 current clinical cases. The four participating radiologists gave correct TV interpretations in 81% of the 39 selected cases presented at the beginning of the experiment. This value reached 94% for the other 28 selected cases presented after three months of regular use of the TV system. With current clinical cases, the agreement between TV and direct interpretations was 93%. Although magnification was available, correct identification of very small lesions proved to be the major source of error. On the whole, the radiologists were satisfied with the TV system.

    Television transmission of diagnostic and educational information can help to improve specialized medical care in remote and underserviced areas. This paper describes a pilot study in which the Canadian satellite Anik-B was used to link the James Bay area in northern Quebec with two large Montreal teaching hospitals. Broad-band real-time television was well suited for tele-education and teleconsultation activities. A much less costly method, using narrow-band slow-scan television, was also examined, but it requires improvements. The technology of telemedicine is in place, but its future use is impeded by the prohibitive costs of operating an efficient two-way broad-band television system for several remote health care sites. A solution to this problem may be an intermediate-band system combining some of the low-cost features of narrowband slow-scan television with the interactive high-resolution advantages of broad-band real-time television.

    1998-12-31

    The Montreal Protocol on Substances that Deplete the Ozone Layer was signed by 24 countries in 1987, establishing measures for controlling the production and consumption of ozone-depleting substances. This publication begins with some background information on ozone depletion and the history of the Protocol. It then describes aspects of the Protocol`s Multilateral Fund, created to assist developing countries to meet Protocol deadlines: Its administration, structure, and how projects are initiated. Names, addresses, and phone/fax numbers of Fund contacts are provided. Canadian projects under the Fund are then reviewed and opportunities for Canadian environmental companies are noted. Finally, information sheets are presented which summarize Fund-related Canadian bilateral projects undertaken to date.

    OBJECTIVE: To determine the seroprevalence and correlates of HIV infection in a subpopulation of women of childbearing age in Montreal. DESIGN: Anonymous unlinked seroprevalence study. SETTING: Pregnancy termination unit in a teaching hospital in Montreal. PARTICIPANTS: Women presenting for abortion from July 1989 to June 1993 who resided in Quebec and were not known to have HIV infection; 12,017 (99.6%) of 12,068 eligible women were included in the study. INTERVENTION: HIV antibody testing of serum left over from samples obtained for routine Rh typing; the same algorithm as for serodiagnostic testing, namely enzyme immunoassay (EIA) followed by confirmatory testing of repeatedly EIA-reactive samples, was used. OUTCOME MEASURES: HIV serostatus by age, marital status, region of residence (metropolitan Montreal versus other), country of birth and number of living children. RESULTS: Most (84.7%) of the subjects resided in metropolitan Montreal. The median age was 27.0 (range 13 to 50) years. The serum samples of 22 women were confirmed to be HIV positive, for an overall seroprevalence rate of 1.8 per 1000 (95% confidence interval 1.1 to 2.8). The seroprevalence rate did not vary significantly by age, marital status, region of residence or study year. However, it was strongly correlated with country of birth: Canada 0.16, Haiti 23.5, HIV-endemic countries other than Haiti 5.3 and non-HIV-endemic countries other than Canada 0.0 per 1000. The seroprevalence rate among women born in Haiti was 147 times higher than that among women born in Canada (p < 0.0001). Of the women born in Haiti the rate was 3.0 times greater among those who immigrated to Canada in 1985 or later than among those who immigrated earlier (p = 0.047). CONCLUSIONS: The results of this study indicate that the HIV seroprevalence rate among women in Montreal is strongly associated with country of birth, women born in HIV-endemic countries, especially Haiti, having the highest rate. These results will help

    These images of Canada's Quebec province were acquired by the Multi-angle Imaging SpectroRadiometer on March 4, 2001. The region's forests are a mixture of coniferous and hardwood trees, and 'sugar-shack' festivities are held at this time of year to celebrate the beginning of maple syrup production. The large river visible in the images is the northeast-flowing St. Lawrence. The city of Montreal is located near the lower left corner, and Quebec City, at the upper right, is near the mouth of the partially ice-covered St. Lawrence Seaway.

    Both spectral and angular information are retrieved for every scene observed by MISR. The left-hand image was acquired by the instrument's vertical-viewing (nadir) camera, and is a false-color spectral composite from the near-infrared, red, and blue bands. The right-hand image is a false-color angular composite using red band data from the 60-degree backward-viewing, nadir, and 60-degree forward-viewing cameras. In each case, the individual channels of data are displayed as red, green, and blue, respectively.

    Much of the ground remains covered or partially covered with snow. Vegetation appears red in the left-hand image because of its high near-infrared brightness. In the multi-angle composite, vegetated areas appear in shades of green because they are brighter at nadir, possibly as a result of an underlying blanket of snow which is more visible from this direction. Enhanced forward scatter from the smooth water surface results in bluer hues, whereas urban areas look somewhat orange, possibly due to the effect of vertical structures which preferentially backscatter sunlight.

    The data were acquired during Terra orbit 6441, and cover an area measuring 275 kilometers x 310 kilometers.

    Cities are a key system in anthropogenic phosphorus (P) cycling because they concentrate both P demand and waste production. Urban agriculture (UA) has been proposed as a means to improve P management by recycling cities' P-rich waste back into local food production. However, we have a limited understanding of the role UA currently plays in the P cycle of cities or its potential to recycle local P waste. Using existing data combined with surveys of local UA practitioners, we quantified the role of UA in the P cycle of Montreal, Canada to explore the potential for UA to recycle local P waste. We also used existing data to complete a substance flow analysis of P flows in the overall food system of Montreal. In 2012, Montreal imported 3.5 Gg of P in food, of which 2.63 Gg ultimately accumulated in landfills, 0.36 Gg were discharged to local waters, and only 0.09 Gg were recycled through composting. We found that UA is only a small sub-system in the overall P cycle of the city, contributing just 0.44% of the P consumed as food in the city. However, within the UA system, the rate of recycling is high: 73% of inputs applied to soil were from recycled sources. While a Quebec mandate to recycle 100% of all organic waste by 2020 might increase the role of UA in P recycling, the area of land in UA is too small to accommodate all P waste produced on the island. UA may, however, be a valuable pathway to improve urban P sustainability by acting as an activity that changes residents' relationship to, and understanding of, the food system and increases their acceptance of composting.

    OBJECTIVE: To measure the HIV seroprevalence rate in a surrogate sample of the general population in the province of Quebec, using a network of sentinel hospitals. DESIGN: Anonymous unlinked sentinel surveillance study. SETTING: Outpatient surgery units in 19 acute care hospitals throughout Quebec. PARTICIPANTS: All patients attending the outpatient surgery units from November 1990 to October 1992. A total of 61,547 plasma samples were obtained from leftover blood samples collected for cell counts. Fifty samples were excluded because of an insufficient amount of plasma and one because of an indeterminate result. INTERVENTION: HIV antibody testing with enzyme-linked immunosorbent assay; positive results confirmed with radioimmunoprecipitation assay. OUTCOME MEASURES: HIV antibody status, sex, year of birth and area of residence. RESULTS: The crude seroprevalence rate among the subjects aged 15 years or more was 0.4 per 1000 population (95% confidence interval [CI] 0.2 to 0.7) among the women and 3.6 per 1000 population (95% CI 2.8 to 4.4) among the men (p < 0.001). The rate after adjustment for age, sex and geographic distribution of the study population was 2.3 per 1000 population (95% CI 1.9 to 2.7). The seroprevalence rate among the male patients in the City of Montreal was much higher than the rates elsewhere in the province. It increased progressively during each of the four 6-month intervals of the study: 8.1, 8.7, 13.9 and 18.3 per 1000 respectively (chi 2 linear trend = 4.76; p = 0.029). No similar trends were observed outside Montreal for the male patients. There were too few seropositive female patients to draw any solid conclusion. CONCLUSIONS: Despite the possible drawbacks of a nonrandomized sampling scheme, this study suggests that in the male population the HIV seroprevalence rate is increasing in Montreal and is stable in all other areas of the province. The continued surveillance of HIV infection through anonymous unlinked studies is useful to

    Brahams summarizes a 1989 Quebec Court of Appeal decision in an abortion case and places the ruling in the context of worldwide trends in abortion regulation. In Tremblay v. Daigle (1989 Jul 26), the Quebec court upheld a lower court injunction banning a woman from having an abortion. The injunction had been obtained by the woman's former boyfriend, the putative father. Brahams discusses the current legal status of abortion in Canada, the Daigle court's reasoning, and how the British approach to the legal status of fathers and fetuses in abortion disputes differs from the Canadian. She also briefly summarizes recent abortion-related judicial and regulatory developments in the United States, Ireland, and France. PMID:2569146

    Introduction We know little about the intensity and determinants of interorganisational collaboration within the homeless network. This study describes the characteristics and relationships (along with the variables predicting their degree of interorganisational collaboration) of 68 organisations of such a network in Montreal (Quebec, Canada). Theory and methods Data were collected primarily through a self-administered questionnaire. Descriptive analyses were conducted followed by social network and multivariate analyses. Results The Montreal homeless network has a high density (50.5%) and a decentralised structure and maintains a mostly informal collaboration with the public and cross-sectorial sectors. The network density showed more frequent contacts among four types of organisations which could point to the existence of cliques. Four variables predicted interorganisational collaboration: organisation type, number of services offered, volume of referrals and satisfaction with the relationships with public organisations. Conclusions and discussion The Montreal homeless network seems adequate to address non-complex homelessness problems. Considering, however, that most homeless individuals present chronic and complex profiles, it appears necessary to have a more formal and better integrated network of homeless organisations, particularly in the health and social service sectors, in order to improve services.

    In 1995 the Montreal Regional Health and Social Services Board began a major process of change to its health care system. This transformation places particular emphasis on primary health care and increases the role of local community services centres (CLSCs) and community organizations (COs). In order to understand this process as experienced by COs, the present exploratory study was conducted during the summer and fall of 1996. We targeted 12 COs, 4 CLSCs, the Quebec Federation of CLSCs, and the Montreal CLSC Working Group. Semi-structured group interviews and CO documents were used as sources of information. Most participants believe in the need for change but feel that the strategies and implementation have been mismanaged. COs are feeling the pressure to professionalize and specialize current and future services. The "social economy" appears to be gaining momentum in the health sector. PMID:10910565

    The Quebec Waste Management Policy (1998-2008) is requesting that the municipalities prepare a waste management plan, including a global objective of 60% of these wastes to be diverted from landfill sites by reduction, re-usage, recycling and valorization. Around 5.8 million tons of wastes were generated on the territory of the Montreal Metropolitan Community in 2001 for a population of about 3.5 millions citizens. In this paper, we present different management scenarios in which anaerobic digestion was used as a valorization step, focusing on the energetic value of the methane produced and the reduction in greenhouse gas (GHG) emissions. The four scenarios prepared cover the valorization of the organic fraction of municipal solid wastes, green wastes and excess sludge and showed potential methane generation of 17-140 Mm3 with a GHG reduction of 62,000-500,000 tons of CO2-equivalents.

    Ozone depletion is caused by the anthropogenic increase of halogen containing species in the atmosphere, which results in the enhancement of the concentration of reactive chlorine and bromine in the stratosphere. To reduce the influence of anthropogenic ozone-depleting substances (ODS), the Montreal Protocol was agreed by Governments in 1987, with several Amendments adopted later. In order to assess the benefits of the Montreal Protocol and its Amendments (MPA) on ozone and UV radiation, two different runs of the chemistry-climate model (CCM) SOCOL have been carried out. The first run was driven by the emission of ozone depleting substances (ODS) prescribed according to the restrictions of the Montreal Protocol and all its Amendments. For the second run we allow the ODS to grow by 3% annually. We find that the MPA would have saved up to 80% of the global annual total ozone by the end of the 21st century. Our calculations also show substantial changes in surface temperature and precipitations that could occur in the world without MPA implementations. To illustrate the changes in UV radiation at the surface and to emphasize certain features which can only be seen for some particular regions if the influence of the cloud cover changes is accounted for, we calculate geographical distribution of the erythemally weighted irradiance (Eery). For the no Montreal Protocol simulation Eery increases by factor of 4 to 16 between the 1970s and 2100. For the scenario including the Montreal Protocol it is found that UV radiation starts to decrease in 2000, with continuous decline of 5% to 10% at middle latitudes in the Northern and Southern hemispheres.

    BACKGROUND: The first heart transplantation in Canada was performed in 1968 at the Montreal Heart Institute (Montreal, Quebec). After nine patients transplanted in the precyclosporine era, the program was stopped. With the advent of cyclosporine, the program was reactivated in 1983. OBJECTIVE: To review the experience of the Montreal Heart Institute with heart transplantation between 1983 and 2005. METHODS: Three hundred patients underwent heart transplantation and were followed at the transplant clinic. Patients were divided into two groups: group 1 – first decade (1983 to 1993, n=145) and group 2 – second decade (1994 to 2005, n=155). RESULTS: There were 125 men (86%) and 20 women (14%) with a mean age of 45±10 years in group 1 compared with 118 men (76%) and 37 women (24%) with a mean age of 48±12 years in group 2 (P=0.03 and P=0.02, respectively). Indications for transplantation included congestive heart failure and/or ischemic heart disease in the majority of patients of both groups, with 83% in group 1 and 73% in group 2, respectively. In group 1, 30 patients (21%) required preoperative pharmacological support and 13 patients (9%) were on mechanical support compared with 16 (10%) and 34 (22%) patients in group 2 (P<0.01). The mean age of donors was 27±10 years and 34±13 years in groups 1 and 2, respectively (P<0.01). Major causes of mortality for donors included a motor vehicle accident in 65 cases (45%) and brain hemorrhage in 43 cases (30%) in group 1 compared with 34 cases (22%) and 68 cases (44%) in group 2 donors (P<0.01). The one-, five- and 10-year actuarial survival rates were 86%, 77% and 71%, respectively, in group 1 compared with 84%, 80% and 68%, respectively, in group 2 (P=0.95). The one-, five- and 10-year freedom from rejection rates were 35%, 28% and 25%, respectively, in group 1 compared with 41%, 36% and 33%, respectively, in group 2 (P=0.13).

    Temporal and geographical variabilities in the future "World Expected" UV environment are compared with the "World Avoided", which would have occurred without the Montreal Protocol on protection of the ozone layer and its subsequent amendments and adjustments. Based on calculations of clear-sky UV irradiances, the effects of the Montreal Protocol have been hugely beneficial to avoid the health risks, such as skin cancer, which are associated with high UV, while there is only a small increase in health risks, such as vitamin D deficiency, that are associated with low UV. However, interactions with climate change may lead to changes in cloud and albedo, and possibly behavioural changes which could also be important.

    This research examines the relationship between community unemployment and the physical and mental health of immigrants in comparison to non-immigrants in Montreal under the hypothesis that high unemployment in the community may generate more negative effects on the health of immigrants than on non-immigrants. Possible gender differences in these associations are also examined. Montreal residents were studied via multilevel analysis, using both individual survey data and neighbourhood data from 49 police districts. Individual-level data were excerpted from a 1998 health survey of Montreal residents, while neighbourhood data originated from survey data collected in the 49 Montreal police districts and the 1996 Canadian Census. The associations between community unemployment and self-rated health, psychological distress and obesity are examined, and hypotheses regarding the modifying mechanisms via which male and female immigrants may run a greater risk of poor health than non-immigrants when living in areas of high unemployment were tested. Between neighbourhoods, variations in the three health outcomes were slight, and differences in health were not associated with differences in community unemployment. The associations between community unemployment and health varied according to immigration status. At the individual level, immigrants do not differ from non-immigrants with respect to the three health indicators, except that second-generation males are slightly heavier. However, when living in areas of high unemployment, immigrants tend to report poor physical and mental health in comparison to non-immigrants. Among first-generation immigrants, community unemployment was associated with psychological distress. Among second-generation immigrants, the probability of obesity and poor self-rated health increased significantly for those living in areas with high unemployment, but these associations reached statistical significance only for men.

    The production of coherent radiation at ever shorter wavelengths has been a long-standing challenge since the invention of lasers and the subsequent demonstration of frequency doubling. Modern X-ray free-electron lasers (FELs) use relativistic electrons to produce intense X-ray pulses on few-femtosecond timescales. However, the shot noise that seeds the amplification produces pulses with a noisy spectrum and limited temporal coherence. To produce stable transform-limited pulses, a seeding scheme called echo-enabled harmonic generation (EEHG) has been proposed, which harnesses the highly nonlinear phase mixing of the celebrated echo phenomenon to generate coherent harmonic density modulations in the electron beam with conventional lasers. Here, we report on a demonstration of EEHG up to the 75th harmonic, where 32 nm light is produced from a 2,400 nm laser. We also demonstrate that individual harmonic amplitudes are controlled by simple adjustment of the phase mixing. Results show the potential of laser-based manipulations to achieve precise control over the coherent spectrum in future X-ray FELs for new science.

    Following changes to the Interim Federal Health (IFH) program in Canada in 2012, this study investigates health service providers' knowledge of the healthcare coverage for refugee claimants living in Quebec. An online questionnaire was completed by 1,772 staff and physicians from five hospitals and two primary care centres in Montreal. Low levels of knowledge and significant associations between knowledge and occupational group, age, and contact with refugees were documented. Social workers, respondents aged 40-49 years, and those who reported previous contact with refugee claimants seeking healthcare were significantly more likely to have 2 or more correct responses. Rapid and multiple changes to the complex IFH policy have generated a high level of confusion among healthcare providers. Simplification of the system and a knowledge transfer strategy aimed at improving healthcare delivery for IFH patients are urgently needed, proposing easy avenues to access rapidly updated information and emphasizing ethical and clinical issues.

    BACKGROUND: Mechanical circulatory support systems (MCSS) have been available in Canada since 1986. Accepted indications include bridging to transplantation or recovery. The present study reviewed the results following MCSS implantation at the Montreal Heart Institute (Montreal, Quebec). METHODS: From September 1987 to September 2006, 43 MCSS were implanted (32 Thoratec [Thoratec Corporation, USA], nine Cardio West TAH [SynCardia Systems Inc, USA], two Novacor [World Heart Corporation, Canada]) in 43 patients (mean [± SD] age 44±13 years; range 19 to 64 years). Indications for implantation included cardiogenic shock due to ischemic (n=19), viral (n=10) or other types of cardiomyopathies (n=14). RESULTS: The mean ejection fraction before implantation was 17.6±6.5% (range 10% to 45%). Before MCSS implantation, most patients showed signs of end-organ failure, including mechanical ventilation (77%), central venous pressure higher than 16 mmHg (44%), oliguria (35%) and hepatic dysfunction (19%). The mean duration of MCSS support was 22.8±32.8 days (range one to 158 days). Survival to transplantation or recovery was 74%. Only one patient was successfully bridged to recovery. Complications were common during MCSS support. They included re-exploration for bleeding (47%), respiratory failure (44%), renal failure requiring temporary dialysis (40%), infection (33%) and neurological events (16%). Only one patient had device failure. In patients successfully bridged to transplantation, early actuarial survival (one month) following transplantation averaged 71±8% and was 57±9% at one year. CONCLUSION: MCSS support with a left ventricular assist device or a total artificial heart provides an effective means of bridging terminally ill patients to transplantation or recovery. Early survival after transplantation shows satisfactory results. However, these results come at the expense of frequent device-related complications, and device failure remains a constant threat.

    Abstract Objective To compare quality-of-care indicators for management of patients with chronic kidney disease (CKD) and type 2 diabetes among the James Bay Cree of Northern Quebec with those among residents of Montreal, Que. Design A cross-sectional survey using medical records from patients seen between 2002 and 2008. Setting Predialysis clinics of the McGill University Health Centre in Montreal. Participants Thirty Cree and 51 nonaboriginal patients older than 18 years of age with type 2 diabetes mellitus and estimated glomerular filtration rates of less than 60 mL/min/1.73 m2. Main outcome measures Rates of anemia, iron deficiency, obesity, and renoprotective medication use among aboriginal and nonaboriginal patients. Results Overall, the Cree patients were younger (59 vs 68 years of age, P < .0035) and weighed more (101 vs 77 kg, P < .001). The 2 groups were prescribed medication to control blood pressure, lipids, and phosphate levels at similar rates, but the Cree patients were more likely to receive renoprotective agents (87% vs 65%, P = .04). Despite similar rates of erythropoietin supplementation, the Cree patients were at greater risk of anemia, with an adjusted risk ratio of 2.80 (95% CI 1.01 to 7.87). Conclusion Cree patients with CKD were younger, weighed more, and were more likely to receive renoprotective agents. With the exception of the management of anemia, quality of CKD care was similar between the 2 groups. Anemia education for family physicians and continuous monitoring of quality indicators must be implemented in northern Quebec. PMID:22439172

  11. Global environmental politics: Lessons from Montreal

    When 24 nations and the European Community signed the Montreal Protocol in September, 1987, it was widely praised for its reflection of unprecedented foresight in mandating preventive action on a global scale. Such praise may have been premature in light of more recent revelations that: (1) the rates of ozone depletion appear to be accelerating; and (2) the depletion seems to be spreading into the summer months over the north temperate zone of latitudes. Although there is still controversy over what the effects of such depletion ultimately will be, most nations of the world, including all of the advanced industrialized countries, agree that chlorofluorocarbons (CFCs) must be phased out of all production and use, and they are taking steps to do that before the turn of the century. Two distinctly different conclusions are thus possible regarding the outcome of the negotiations. As the first successfully negotiated multilateral agreement to address a global environmental problem, the Protocol is seen by many to be a triumph of environmental awareness and international cooperation. To other observers, however, the struggle for domestic commercial interests and national political debates that led to delays in action may already be causing serious and irreversible damage that could have been avoided. In short, the negotiation process worked, but it took to long for nations to agree that it was necessary and to begin the process.

    2014-01-01

    On May 19, 2013, a consulting physician contacted the Laurentian Regional Department of Public Health (Direction de santé publique des Laurentides [DSP]) in Quebec, Canada, to report that two masons employed by the same company to do demolition work were experiencing cough and dyspnea accompanied by fever. Other workers also were said to be ill. DSP initiated a joint infectious disease, environmental health, and occupational health investigation to determine the extent and cause of the outbreak. The investigation identified 14 persons with respiratory symptoms among 30 potentially exposed persons. A strong correlation was found between exposure to demolition dust containing bat or bird droppings and a diagnosis of histoplasmosis. Temporary suspension of construction work at the demolition site in Saint-Eustache, Quebec, northwest from Montreal, and transport of the old masonry elements to a secure site for burial were ordered, and information about the disease was provided to workers and residents. To prevent future outbreaks, recommendations included disinfection of any contaminated material, disposal of waste material with proper control of aerosolized dust, and mandatory use of personal protective equipment such as gloves, protective clothing, and adequate respirators.

    IN Quebec (Canada), the utilization of dental care services varies greatly from one social class to another: whereas the well-to-do visit the dentist often for check-ups, those most in need demonstrate a "wait-and-see" attitude. The objective of our research was to describe the dental care pathway of the underprivileged when confronted with symptoms, and to understand how this pathway might be interrupted and possibly lead to tooth extractions. We arranged 16 one-on-one interviews with adult Montrealers who had experienced a dental problem during the 12 months preceding the interview. These participants, 9 women and 7 men aged between 30 and 48, lived in great poverty: all were welfare recipients, and as such, enjoyed the benefits of a government programme that entitled them to free basic dental care. During the interviews, the interviewers asked the participants to describe their latest dental problem and their subsequent behaviour. The dental care pathway of our participants was characterized by a strategy of adapting to the symptoms. This process of adapting, which can last several months, is essentially an individual process in which the individuals often resort to self-medication to soothe their pain. They decide to visit a dentist when the pain is too great and self-medication is no longer effective. Once this decision is made, their dental care pathway may nevertheless be interrupted in two ways: first, in the failure to find a dentist, and second, later, in the failure to complete treatments that are not covered by the welfare program, such as endodontic treatment. The fragmented character of these dental care pathways refers us to two features of accessibility: financial accessibility and acceptability. With regard to financial accessibility, our study shows that the public coverage intended for welfare recipients presents major gaps. As for acceptability, our participants are strongly critical of the dental profession, and develop a culture of rejection

    When New York governor Mario Cuomo pulled the plug on a purchase of 1,000 megawatts of power from Hydro-Quebec last June, the provincial utility talked tough. The cancellation, a senior Hydro-Quebec official claimed, would not jeopardize the future of its controversial Great Whale hydro project in the North. Bu Hydro-Quebec has quietly shoved Great Whale onto the back burner while an environmental review is underway. In the meantime the utility is barreling ahead with another mega-dam. The Ste. Marquerite project planned for north-eastern Quebec is modest by Hydro-Quebec standards, generating less than a third the power of Great Whale. Still, with an 880-megawatt power station and 190 square miles of reservoirs, it is one of the largest hydro projects on any drawing board in North America. Environmentalists say it is being pushed ahead without a serious study of its impacts. This article details the environmental impacts of the project, and the extended impacts, not yet accounted for.

  16. Mergers and integrated care: the Quebec experience

    Demers, Louis

    2013-01-01

    As a researcher, I have studied the efforts to increase the integration of health and social services in Quebec, as well as the mergers in the Quebec healthcare system. These mergers have often been presented as a necessary transition to break down the silos that compartmentalize the services dispensed by various organisations. A review of the studies about mergers and integrated care projects in the Quebec healthcare system, since its inception, show that mergers cannot facilitate integrated care unless they are desired and represent for all of the actors involved an appropriate way to deal with service organisation problems. Otherwise, mergers impede integrated care by creating increased bureaucratisation and standardisation and by triggering conflicts and mistrust among the staff of the merged organisations. It is then preferable to let local actors select the most appropriate organisational integration model for their specific context and offer them resources and incentives to cooperate. PMID:23687474

  4. Human genetics: lessons from Quebec populations.

    PubMed

    Scriver, C R

    2001-01-01

    The population of Quebec, Canada (7.3 million) contains approximately 6 million French Canadians; they are the descendants of approximately 8500 permanent French settlers who colonized Nouvelle France between 1608 and 1759. Their well-documented settlements, internal migrations, and natural increase over four centuries in relative isolation (geographic, linguistic, etc.) contain important evidence of social transmission of demographic behavior that contributed to effective family size and population structure. This history is reflected in at least 22 Mendelian diseases, occurring at unusually high prevalence in its subpopulations. Immigration of non-French persons during the past 250 years has given the Quebec population further inhomogeneity, which is apparent in allelic diversity at various loci. The histories of Quebec's subpopulations are, to a great extent, the histories of their alleles. Rare pathogenic alleles with high penetrance and associated haplotypes at 10 loci (CFTR, FAH, HBB, HEXA, LDLR, LPL, PAH, PABP2, PDDR, and SACS) are expressed in probands with cystic fibrosis, tyrosinemia, beta-thalassemia, Tay-Sachs, familial hypercholesterolemia, hyperchylomicronemia, PKU, oculopharyngeal muscular dystrophy, pseudo vitamin D deficiency rickets, and spastic ataxia of Charlevoix-Saguenay, respectively) reveal the interpopulation and intrapopulation genetic diversity of Quebec. Inbreeding does not explain the clustering and prevalence of these genetic diseases; genealogical reconstructions buttressed by molecular evidence point to founder effects and genetic drift in multiple instances. Genealogical estimates of historical meioses and analysis of linkage disequilibrium show that sectors of this young population are suitable for linkage disequilibrium mapping of rare alleles. How the population benefits from what is being learned about its structure and how its uniqueness could facilitate construction of a genomic map of linkage disequilibrium are discussed

The reasons for using such a system and the way it was carried out are discrete.

    Cancer prevalence is of prime interest in public health because of its use in estimating the disease's burden on the heath care system. This study's objective was to estimate five-year prevalence of tumours from 1989 to 1999 and ten-year prevalence of tumours from 1994 to 1999 in the Province of Quebec (Canada). Five-year prevalence was used to represent tumours for which people are more likely to obtain primary treatment; ten-year prevalence included those tumours in addition to tumours that can be considered cured but still need follow-up. Information was extracted from the Quebec Cancer Registry. Prostate cancer was the most prevalent malignancy among males (25 percent, five-year prevalent tumours), while breast cancer was most prevalent among females (38 percent, five-year prevalent tumours). For both sexes, the greatest observed prevalence increase was for endocrine glands. On average, five-year prevalence proportions were 16 percent higher in men than in women; those of ten year were 14 percent higher in men. Furthermore, the largest differences were observed for bladder and lung cancer. The change in cancer prevalence in Quebec was dependent on the tumour site. PMID:17306062

    2001-02-16

    This paper describes a case study in which advanced chemical fingerprinting and data interpretation techniques were used to characterize the chemical compositions and determine the source of an unknown spilled oil from Quebec. On 28 February 1999, significant amounts of oil was reported on the river banks of St. Laurence River in front of a company named "Thermex" (in a town - Beauharnois, Quebec, about 50 km northwest of Montreal). The spilled oil was suspected to be released from a nearby factory. In response to this specific site investigation needs, a tiered analytical approach using GC-MS and GC-flame ionization detection was applied. A variety of diagnostic ratios of "source-specific marker" compounds, in particular isomers of biomarkers and alkylated series of polycyclic aromatic hydrocarbons within the same alkylation groups, were determined and analyzed. The hydrocarbon analysis results reveal the following: (1) the spilled oil is very "specific", and is significantly different from most crude oils in chemical composition; (2) the oil in samples come from the same source, however, the spill sample 2569 was identified to contain a small amount (approximately 10%) of diesel; (3) the spilled oil was relatively "fresh", its chemical composition has not undergone significant alteration yet; (4) the spilled oil showed unusually high concentration of the US Environmental Protection Agency priority polycyclic aromatic hydrocarbons (PAHs). The "Pyrogenic Index" values were determined to be as high as 0.11-0.13, significantly higher than crude oils (<0.010) and heavy Bunker type fuels (0.015-0.060). This indicates significant contribution of PAH composition from pyrogenic components; (5) biomarkers were also detected, but their concentrations were unusually low in comparison to most crude oils.

    A case study of state corporations in the forestry, mining, and petroleum sectors in resource frontier regions reveals the extent of state involvement in infrastructure and production in Quebec. The intention of government corporations was to encourage Quebec enterprise, to promote resource extraction in hinterland regions, and to contribute to the ''economic liberation'' of Quebec, as part of a regional policy of ''maitres chez nous.'' A complex set of relationships involving regional and international investments, ideology, and economic nationalism are discussed for the period 1960-1980. It is concluded that the state has become an integral part of regional development in selected resource frontier regions in Quebec.

    The golden cyst nematode (Globodera rostochiensis), native to South America, has been introduced in many parts of the world, including Europe and North America. Recently, it was found for the first time in the province of Quebec, Canada in the locality of St. Amable near Montreal. To date, very few studies have examined the population genetics of this pest. Consequently, there is a lack of knowledge about the genetic structure and evolution of this nematode. In this study, twelve new microsatellite markers were developed in order to explore these questions. These markers were used to genotype fifteen populations originating from different regions of the world, including five from Canada. Within populations, the highest genetic diversity was consistently observed in the populations from Bolivia, the postulated region of origin of the golden nematode, and the lowest in populations from British Columbia (Canada) and New York (USA). The two Quebec populations were very similar to each other and to the population found in Newfoundland, but surprisingly, they were significantly different from three other North American populations including those from New York and British Columbia. Based on our results, we conclude that the golden cyst nematode has been introduced in North America at least twice from distinct regions of the world. PMID:23742887

    This text narrates the evolution, since the 1960s, of different events that marked the history of psychiatry in the French-Canadian province of Quebec. From his personal experience, the author discusses. The evolution of the Départment de psychiatric de l'Université de Montréal fro where were issued more than 1000 psychiatrists who shaped clinical practice and research developments worthy of mention throughout the years. The evolution of diagnostic noselogy from the DSM-ii, very influenced by psychoanalysis, to the DSM-5 that is more atheortical, but that is still not based on objective data, which remains a challenge to the etiology of mental illness. The psychiatric drugs that we have learned to prescribe in the past 50 years in a more rational way thanks to a better understanding of their action mechanisms. In reality, there has been no discovery of new drug categories; rather it is the way we prescribe medication that evolved. The great adventure of the first textbook of Quebec psychiatry, which was first published in 1980, and is forthcoming in its 4th edition in 2015 in an improved and expanded format.

    "The goal of this paper is to review those explanatory models that dominate social demography in Quebec. The classical organization of demography, which calls upon the three components of demographic reproduction--fertility, migration and mortality--is followed. The concluding part of the paper deals with the concept of 'demographic regime', which aims to bring the three components together into an overall theory of demographic reproduction. The paper shows that if the functionalist and empirical tradition (mostly American) has dominated the field of demography for a very long time, feminist and materialistic approaches have recently appeared for the interpretation of demographic realities."

    In the last decade, it has become apparent that the regulation ofozone depleting substances (ODS) by the Montreal Protocol has hadprofound impacts on the climate system, affecting not only surfacetemperatures but also the atmospheric circulation and the entirehydrological cycle. In this study we demonstrate that he MontrealProtocol will also be very effective in mitigating the potentialintensity (PI) of hurricanes in the coming half century. We accomplish this by comparing the projections of a standard CMIP5RCP4.5 scenario to those of the so-called "World Avoided" scenario, inwhich ODS grow unabated in the absence of regulations. For thiscomparison, we use ouput from two 3-member ensembles of WholeAtmosphere Community Climate Model (WACCM), integrated between 2005and 2065. WACCM is the most comprehensive member of the CommunityEarth System Models (CESM), and includes interactive stratosphericchemistry, in addition to coupled land, ocean, and sea-ice components, In the World Avoided projections we find that the hurricane PI issubstantially larger that in the standard RCP4.5 case. Specifically,over the decade 2056-2065, the increase in PI is comparable to the onebetween RCP4.5 and RCP8.5 for the entire multi-model mean of the CMIP5models. Similar to what is projected by the CMIP5 models forincreasing CO2, in the World Avoided scenario the increase in hurricanPI is due to a combined increase in sea surface temperature and CAPE,and a decrease in the temperature in upper levels, near 70hPa. Our WACCM simulations indicate that the mitigating effect of theMontreal Protocol is highly significant: without ODSs regulations thePI would be twice as large as currently projected by the middle ofthis century.

    The Montreal Protocol, an international treaty designed to reduce the release into the atmosphere of ozone-depleting gases such as hydrochlorofluorocarbons and chlorofluorocarbons, has been successful since its implementation in the late 1980s. However, related greenhouse gases, such as hydrofluorocarbons (HFCs), have increased in concentration in the atmosphere since then. HFCs, along with other synthetic greenhouse gases (SGHGs), account for a radiative forcing almost 20% as large as that due to the increase in carbon dioxide (CO2) since the preindustrial era.

    The cooperation of China and India in replacing chemicals that damage the stratospheric ozone layer is critical to the success of the world`s first environmental agreement, the Montreal Protocol. China`s leaders accepted the agreement more readily than did their Indian counterparts. These divergent responses are attributed to the nature of the policy issue in question, the impact of regime type upon state leaders` environmental policies, and dissimilar linkages between international and domestic actors and forces. The author examines these divergent responses.

    Abstract Objective To describe the management and distribution of drug samples in family medicine teaching units (FMUs). Design Cross-sectional descriptive study. Setting All 16 FMUs affiliated with the Department of Family Medicine and Emergency Medicine at the University of Montreal in Quebec. Participants Health care professionals (physicians, residents, pharmacists, and nurses) who manage (n = 22) and dispense (n = 294) drug samples in the FMUs. Methods Data were collected between February and March 2013 using 2 self-administered questionnaires completed by health care professionals who manage or dispense drug samples. The data were subjected to descriptive and bivariate analyses. Results The participation rate was 100.0% for staff who manage drug samples and 72.5% for those who dispense them. Of the 16 participating FMUs, 12 have drug sample cabinets. Eight of the FMUs have a written institutional policy governing the management of drug samples. Of the 76.2% of respondents who said they distributed samples, more than half did not know whether their institution had a policy. In 7 of 12 FMUs with drug sample cabinets, access to samples is not restricted to those authorized to prescribe medications. Cabinets are most often managed by nurses (9 of 12 FMUs). Only 4 of 12 FMUs take regular inventory of cabinet contents. The main reasons cited for dispensing samples were to help a patient financially and to test for tolerance and efficacy when initiating or modifying a treatment for a patient. Three-quarters (78.2%) of dispensers reported that sometimes they were unable to find the drug they wanted in the cabinet; half of those consequently gave patients drugs that were not their first choice. More than half the dispensers reported they never or only occasionally referred patients to their community pharmacists. Conclusion A portrait of drug sample management and dispensation in the academic FMUs emerged from this study. This study provides insight into current

    Physico-chemical data from 234 lakes were collected during the spring and summer of 1980 by the Quebec Ministry of the Environment, the Quebec Ministry of Recreation, Hunting and Fishing and the Canadian Wildlife Service. A statistical method, based on the joint use of factorial correspondence analysis and cluster analysis, was applied to these data to obtain a general picture of the spatial variability of a member of physico-chemical parameters related to the sensitivity or acidification of lakewaters. This method was first applied to the entire Quebec territory, and showed that the part of Quebec lying on the Canadian shield is especially vulnerable to acidification. The method also showed that the southwestern portion of this area of Quebec was more substantially affected by acid fallout. A detailed study of spatial variability over the shield area revealed the existence of greater spatial heterogeneity. More precisely, it was possible to pinpoint zones which are highly vulnerable to acid precipitation and zones whose lakes show clear signs of acidification resulting from such precipitation. These two statistical analyses led to a first general diagnosis on lake acidification in Quebec. They contribute to the rationalization of data acquisition in Quebec by delimitating zones where network density needs to be increased.

    The literature reports that led to the current acceptance of New Quebec Crater (Chubb Crater) as an authentic impact crater are reviewed, and it is noted that, for reasons that are not entirely clear, a meteoritic origin for the New Quebec Crater achieved wider acceptance at an earlier data than for the Lake Bosumtwi Crater, for which petrographic and chemical evidence is more abundant and compelling. The petrography of two impact melt samples from the New Quebec Crater was investigated, and new evidence is obtained on the degrees of shock metamorphism affecting the accessory minerals such as apatite, sphene, magnetite, and zircon.

    According to data from the most recent edition of the Canadian Rx Atlas, Quebec was the province with the highest total spending per capita on prescription drugs. The difference between Quebec and the rest of Canada was 35%, which translates into $1.5 billion dollars of extra spending. This analysis explores the economic cost drivers of the higher level of pharmaceutical spending in Quebec. While much of the additional spending was driven by a higher volume of drugs being prescribed overall, the factors contributing to higher spending differed greatly within particular therapeutic categories. The results and their implications are discussed in the context of pharmaceutical policy environment. PMID:25617512

    Unlike many of my contemporaries, I did not begin my career with CFCs, ozone, and the Montreal Protocol. Instead, I began with climate change issue. In October 1989 I became Director of the Department of State's Office of Global Change, after the George H.W. Bush Administration agreed to host the Third Plenary of the Intergovernmental Panel on Climate Change (IPCC) at Georgetown University. Bert Bolin was IPCC Chair, Bill Reilly was EPA Administrator and John Sununu was White House Chief of Staff. I survived those early years and afterward had a long run with the climate change policy - lasting through six administrations. Last year I even chaired the Ad Hoc Group on Long-Term Cooperative Action in Durban at the 17th Conference of the Parties under the UN FCCC. I really plunged into the ozone issue in 2006 when I became the Deputy Assistant Secretary for Environment. By then ozone was hardly ever mentioned, except to recall that the Montreal Protocol was undoubtedly the most successful multilateral environmental agreement ever undertaken - and to contrast it nostalgically with others that have not fared so well - particularly climate. Even worse, ozone was ancient history and most people thought we had solved that problem. Richard Benedict's Ozone Diplomacy had long been a staple of college courses on the global environment but few graduates saw a career in ozone, and it had become difficult to find people in government who were willing to work on it. In early 2007, my staff and I met with colleagues at EPA to brainstorm about the global effort to phase out chlorofluorocarbons (CFCs) and move to alternatives - hydrochlorofluorocarbons (HCFCs). The transition from CFCs was nearing its end but HCFCs, though less potent, were still a problem for the ozone layer. We began to wonder -- could something be done to accelerate the phaseouts of HCFCs? We realized that proposing an acceleration would mean that developed countries would need to go first. Only later would they

    Background Climate change may lead to more severe and extreme heat waves in the future, but its potential impact on sudden infant death—a leading cause of infant mortality—is unclear. Objectives We sought to determine whether risk of sudden infant death syndrome (SIDS) is elevated during hot weather. Methods We undertook a case-crossover analysis of all sudden infant deaths during warm periods in metropolitan Montreal, Quebec, Canada, from 1981 through 2010. Our analysis included a total of 196 certified cases of SIDS, including 89 deaths at 1–2 months of age, and 94 at 3–12 months. We estimated associations between maximum outdoor temperatures and SIDS by comparing outdoor temperatures on the day of or day before a SIDS event with temperatures on control days during the same month, using cubic splines to model temperature and adjusting for relative humidity. Results Maximum daily temperatures of ≥ 29°C on the same day were associated with 2.78 times greater odds of sudden infant death relative to 20°C (95% CI: 1.64, 4.70). The likelihood of sudden death increased steadily with higher temperature. Associations were stronger for infants 3–12 months of age than for infants 1–2 months of age, with odds ratios of 3.90 (95% CI: 1.87, 8.13) and 1.73 (95% CI: 0.80, 3.73), respectively, for 29°C compared with 20°C on the day of the event. Conclusions High ambient temperature may be a novel risk factor for SIDS, especially at ≥ 3 months of age. Climate change and the higher temperatures that result may account for a potentially greater proportion of sudden infant deaths in the future.

    OBJECTIVES: To compare the practice patterns of female pediatricians in Quebec with those of their male counterparts and to identify specific factors influencing these practice patterns. DESIGN: Matched cohort questionnaire survey. SETTING: Primary, secondary and tertiary care pediatric practices in Quebec. PARTICIPANTS: All 146 female pediatricians and 133 of the 298 male pediatricians, matched for age as well as type and site of practice; 119 (82%) of the female and 115 (86%) of the male pediatricians responded. MAIN OUTCOME MEASURES: Demographic and family data as well as detailed information about the practice profile. RESULTS: The two groups were comparable regarding demographic data, professional work and patient care. Compared with the male respondents, the female pediatricians were younger and saw more outpatients. The mean number of hours worked per week, excluding on-call duty, was 40.5 (standard deviation [SD] 12.4) for the women and 48.9 (SD 12.0) for the men (p < 0.001). The female pediatricians were more likely than their male counterparts to have spouses who were also physicians (40%) or in another profession (45%). The female pediatricians without children worked significantly fewer hours than the male pediatricians with or without children (p < 0.001). Children (p = 0.006), but not the number of children (p = 0.452), had a significant effect on the number of hours worked by the female pediatricians. CONCLUSION: The duality of the role of female physicians as mothers and professional caregivers must be considered during workload evaluations. If the same style of practice and the increase in the proportion of female pediatricians continue, about 20% more pediatricians will be needed in 10 years to accomplish the same workload.

    Communities of practice (CoPs) are among the professional development strategies most widely used in such fields as management and education. Though the approach has elicited keen interest, knowledge pertaining to its conceptual underpinnings is still limited, thus hindering proper assessment of CoPs' effects and the processes generating the latter. To address this shortcoming, this paper presents a conceptual model that was developed to evaluate an initiative based on a CoP strategy: Health Promotion Laboratories are a professional development intervention that was implemented in local public health organizations in Montreal (Quebec, Canada). The model is based on latest theories on work-group effectiveness and organizational learning and can be usefully adopted by evaluators who are increasingly called upon to illuminate decision-making about CoPs. Ultimately, validation of this conceptual model will help advance knowledge and practice pertaining to CoPs as well as professional and organizational development strategies in public health.

This computer-controlled Pockels cell polarimeter has been restored to working order and offers a wide range of possibilities: almost all functions are under remote control, linear or circular polarization observations are both possible, a filter slide provides easy access to up to six different bandpasses, and the Pockels cell and Fabry lenses are kept at a constant temperature. In addition to controlling the instrument, the software allows the use of pre-defined sequences of observation, and does data acquisition and reduction. (SECTION: Astronomical Instrumentation)

  1. Power from the north: The poetics and politics of energy in Quebec

    NASA Astrophysics Data System (ADS)

    Desbiens, Caroline

    In 1971, Robert Bourassa, then Premier of Quebec, launched a major hydroelectric scheme to be built 1400 km North of Montreal. Known as the "James Bay" project, the first phase included the creation of eight powerhouses, six reservoirs and the diversion of two rivers. These transformations necessarily impacted the local Cree people; a territorial agreement partly compensated them but remains controversial to this day. While northern communities overwhelmingly bear the ecological cost of the project, the bulk of James Bay energy flows south to the industrial centers of Quebec, Ontario and the U.S. The assertion then that "James Bay belongs to all the Quebecois" which was meant to ease political tensions about the project begs the question, "Who are the Quebecois" and how do the Crees fit within such a community? This thesis explore that question by looking at the Quebecois cultural production of territory and its resources in the north. If James Bay was out of reach, it was never out of view. Media and political discourses reiterated key elements of a Quebecois cultural relationship to place, some of which are contained in the rural literature known as the roman de la terre. Several elements of this literature and its broader context were recontextualized in James Bay, particularly as they pertained to the will to occupy the land and develop natural resources. This was an important aspect of making James Bay---a land historically inhabited by the Crees---into a "Quebecois" national landscape. I suggest that this process was largely rooted in representations of nature that sought to bind it with nation and national identity. Thus James Bay demonstrates the close connection between identity and environmental struggles. For the Quebecois, the access to James Bay was supported by a territorial discourse that performed their own cultural past. This provoked an organized resistance from the Crees which constituted them as a modern political unit. A look at the cultural

    PubMed Central

    2010-01-01

    Background Crohn's disease (CD) is clinically expressed as a chronic affection of the gastrointestinal tract currently known to have a multifactorial etiology involving a complex pathophysiological host response modulated by genetic susceptibilities, demographic determinants and environmental factors. With more than 20 cases per 100,000 person-years, the province of Quebec, Canada is among regions of the world with highest reported occurrence of CD in relation to other places where comparable estimates are available. This ecological study was designed to provide a medium-scale spatial exploration of CD incidence after accounting for the influence of known population and regional determinants. Health records of consulting patients in southern Quebec were compiled from 1995 to 2000 and used to estimate age and sex standardized rates per health area (n = 156). Various statistical models taking into account the regional effect of Jewish ethnicity, aboriginal ancestry, material deprivation, prescription for oral contraceptives, reportable enteric infection incidence, smoking as well as latitude and longitude locations were fitted. Results The final regression model presented a coefficient of determination of 22.8% and there was evidence of an eastern trend in the residual incidence (p = 0.018). Overall, the smoothed residual incidence presented a heterogeneous spatial pattern with evidence of patches (multiple health areas) of high, low and contrasting values. Health areas with most extreme incidence residuals where also distributed over the whole province including one area in the metropolitan area of Montreal and others in surrounding areas. Conclusions These findings suggest that known populational and regional factors derived through census information only explain a limited fraction of the geographical variation of CD incidence and lead to speculate that the effects of these factors may be incompletely captured (imperfect construction of proxy variables) or that

  3. Earthquake-triggered slumps (1935 Timiskaming M6.2) in Lake Kipawa, Western Quebec Seismic Zone, Canada

    2010-07-01

    The Western Quebec Seismic Zone (WQSZ) of eastern North America is characterised by frequent moderate magnitude intracratonic earthquakes (e.g., 1732, M5.8; 1935, M6.2 and 1944, M5.2). The WQSZ is centered along the Timiskaming and Ottawa-Bonnechere grabens, which form part of a complex aulacogen (St.Lawrence Rift) within the Canadian Shield. The WQSZ includes the urban areas of Montreal and Ottawa but seismic risk analysis is challenged by short instrumental records and long recurrence intervals. The M6.2 1935 Timiskaming Earthquake is the largest recorded to date and was felt over some 1.3 million km 2 of eastern North America with many aftershocks of magnitude 4 to 5. Its epicenter lies below the western margin of Lake Kipawa, Quebec in the area where a major Proterozoic crustal boundary (the Grenville Front Tectonic Zone) crosses the Timiskaming Graben. A high-resolution 'chirp' seismic reflection survey of the lateglacial and postglacial sediment infill of Lake Kipawa reveals a clear record of recent ground shaking that is attributed to the 1935 earthquake. Widespread large slumps record down slope failure of the lateglacial and postglacial sediment fill indicating that the 1935 temblor was the largest in this area since deglaciation some 8000 years ago. Systematic mapping of landslides shows that they extend across an area of 600 km 2 around the earthquake's epicenter. Lakes cover a large area of eastern Canada; a regional-scale survey of lake floors could constrain historic epicenters and postglacial seismic history of the heavily populated WQSZ.

    One hundred ninety-eight groundwater wells were sampled to measure the (222)Rn activity in the region between Montreal and Quebec City, eastern Canada. The aim of this study was to relate the spatial distribution of (222)Rn activity to the geology and the hydrogeology of the study area and to estimate the potential health risks associated with (222)Rn in the most populated area of the Province of Quebec. Most of the groundwater samples show low (222)Rn activities with a median value of 8.6 Bq/L. Ninety percent of samples show (222)Rn activity lower than 100 Bq/L, the exposure limit in groundwater recommended by the World Health Organization. A few higher (222)Rn activities (up to 310 Bq/L) have been measured in wells from the Appalachian Mountains and from the magmatic intrusion of Mont-Saint-Hilaire, known for its high level of indoor radon. The spatial distribution of (222)Rn activity seems to be related mainly to lithology differences between U-richer metasediments of the Appalachian Mountains and magmatic intrusions and the carbonaceous silty shales of the St. Lawrence Platform. Radon is slightly enriched in sodium-chlorine waters that evolved at contact with clay-rich formations. (226)Ra, the parent element of (222)Rn could be easily adsorbed on clays, creating a favorable environment for the production and release of (222)Rn into groundwater. The contribution of groundwater radon to indoor radon or by ingestion is minimal except for specific areas near Mont-Saint-Hilaire or in the Appalachian Mountains where this contribution could reach 45% of the total radioactive annual dose.

    Remote assessments of individuals with a neurological disease via telemedicine have the potential to reduce some of the burdens associated with clinical care and research participation. We aim to evaluate the feasibility of conducting the Montreal Cognitive Assessment remotely in individuals with movement disorders. A pilot study derived from two telemedicine trials was conducted. In total, 17 individuals with movement disorders (8 with Parkinson disease and 9 with Huntington disease) had Montreal Cognitive Assessment examinations evaluated in-person and remotely via web-based video conferencing to primarily determine feasibility and potential barriers in its remote administration. Administering the Montreal Cognitive Assessment remotely in a sample of movement disorder patients with mild cognitive impairment is feasible, with only minor common complications associated with technology, including delayed sound and corrupted imaging for participants with low connection speeds. The Montreal Cognitive Assessment has the potential to be used in remote assessments of patients and research participants with movement disorders. PMID:25391849

    Feral pigeons (Columbia livia) can harbor a range of zoonotic pathogens. A transversal study was undertaken to estimate the prevalence of feral pigeons infected by various pathogens in public areas in Montreal, Quebec. Cloacal swabs from captured birds were cultured for Salmonella spp. and Campylobacter spp. and tested by real-time polymerase chain reaction (RT-PCR) for the detection of Coxiella burnetii. An oropharyngeal swab was also submitted to real-time reverse-transcription polymerase chain reaction (RRT-PCR) for the detection of Newcastle disease virus. Among the 187 pigeons tested from 10 public areas, 9.1% (95% CI: 3.0 to 15.2) were positive for Campylobacter spp. with all strains identified as Campylobacter jejuni. The Campylobacter status of birds was not associated with individual characteristics of birds, with the exception of body score. None of the pigeons tested positive for the other pathogens. Direct or indirect contacts with feral pigeons may constitute a potential risk for Campylobacter infection in humans. PMID:26733736

    Feral pigeons (Columbia livia) can harbor a range of zoonotic pathogens. A transversal study was undertaken to estimate the prevalence of feral pigeons infected by various pathogens in public areas in Montreal, Quebec. Cloacal swabs from captured birds were cultured for Salmonella spp. and Campylobacter spp. and tested by real-time polymerase chain reaction (RT-PCR) for the detection of Coxiella burnetii. An oropharyngeal swab was also submitted to real-time reverse-transcription polymerase chain reaction (RRT-PCR) for the detection of Newcastle disease virus.

    We investigated the effect of background noise on performance on the Montreal Cognitive Assessment (MoCA). Two groups of older adults (one with clinically normal hearing, one with hearing loss) and a younger adult group with clinically normal hearing were administered two versions of the MoCA under headphones in low and high levels of background noise. Intensity levels used to present the test were customized based on the hearing abilities of participants with hearing loss to yield a uniform level of difficulty across listeners in the high-level noise condition. Both older groups had poorer MoCA scores in noise than the younger group. Importantly, all participants had poorer MoCA scores in the high-noise (M = 22.7/30) compared to the low-noise condition (M = 25.7/30, p < .001). Results suggest that background noise in the test environment should be considered when cognitive tests are conducted and results interpreted, especially when testing older adults. PMID:27345572

  9. The Montreal Criteria for the Ethical Feasibility of Uterine Transplantation.

    2012-04-01

    Absolute uterine factor infertility (UFI) refers to the refractory causes of female infertility stemming from the anatomical or physiological inability of a uterus to sustain gestation. Today, uterine factor infertility affects 3-5% of the population. Traditionally, although surrogacy and adoption have been the only viable options for females affected by this condition, the uterine transplant is currently under investigation as a potential medical alternative for women who desire to go through the experience of pregnancy. Although animal models have shown promising results, human transplantation cases have only been described in case reports and a successful transplant leading to gestation is yet to occur in humans. Notwithstanding the intricate medical and scientific complexities that a uterine transplant places on the medical minds of our time, ethical questions on this matter pose a similar, if not greater, challenge. In light of these facts, this article attempts to present the ethical issues in the context of experimentation and standard practice which surround this controversial and potentially paradigm-altering procedure; and given these, introduces "The Montreal Criteria for the Ethical Feasibility of Uterine Transplantation", a set of proposed criteria required for a woman to be ethically considered a candidate for uterine transplantation.

    Even if home composting can eliminate municipal organic waste collection, handling and treatment costs, its compost quality requires investigation outside the laboratory. A study was thus conducted to evaluate the influence of the following management practices on the compost quality produced by five backyards home composters in Montreal West Island from June to October 2010: the type and backyard location of the home composter (HC), and the rate and type of organic waste (OW) fed into the home composter. The parameters monitored were compost temperature and final characteristics including trace elements and pathogens. For all HC compost, maximum but not necessarily thermophilic temperatures were highly probable within one week of adding more than 10 kg of OW composed of equal volumes of food waste (FW) and yard trimmings (YT). Top and bottom HC perforations enhanced convective aeration but concentrated OW decomposition within the bottom layer. Fed an equal volume of FW and YT, the final HC compost had a dry and organic matter content exceeding 30%, and 50%, respectively, and a total nitrogen, phosphorous and potassium level of 2, 1 and 3% on a dry matter basis, representing a good quality soil amendment. Clean OW feeding resulted in compost respecting Canadian and European regulations for Escherichia coli and Salmonella, irrespective of the temperature regime. For trace elements, regulatory limits may be exceeded when the home composter is fed ashes and soil. Homeowners must also be careful when applying pesticides to their lawns and gardens and then feeding the residues to the home composter. PMID:23393981

    Summary In 2012 Quebec limited continuous in-hospital duty to 16 consecutive hours for all residents regardless of postgraduate (PGY) level. The new restrictions in Quebec appeared to have a profound, negative effect on the quality of life of surgical residents at McGill University and a perceived detrimental effect on the delivery of surgical education and patient care. Here we discuss the results of a nationwide survey that we created and distributed to general surgery residents across Canada to capture and compare their perceptions of the changes to duty hour restrictions.

    This article is a review of Hydro-Quebec`s electric vehicle design efforts. This design incorporates electric motors into each wheel, which is expected to result in high torque at all speeds and improved handling and traction. The design is thought to be highly efficient because: (1) it is better at transforming stored energy into usable mechanical energy, and (2) regenerative braking and better aerodynamics require less energy at the wheels to propel the vehicle. System designers expect to have the system installed in a full-size vehicle (a Chrysler Intrepid) by early 1996, and eventually, Hydro-Quebec expects to sell the technology to automakers.

    1995-11-01

    This paper presents an evolution of the approach to the contaminated soil issue in Quebec. This evolution is directly related to the various programs of the provincial government. Beginning with an inventory of contaminated sites in the province of Quebec, Environment Quebec provided funds specially for development and demonstration projects related to site remediation. Consequently to the program expectation, a cooperation of scientific units, environmental industry and owners of contaminated sites were demonstrated. This paper shows the fluctuation of interest in various R and D topics. This paper also presents a critical point of view of different companies involved in the development of new technologies for soil remediation. As a consequence of the various activities related to the contaminated soil at different levels of interest, a new approach to the problem of contaminated soil in the province of Quebec is presented. New, non-profit organizations such as RESOL, CAS, and GRAPE have been created to improve the effectiveness of site remediation and lead the R and D in the correct direction. The pollutants of concern are organic compounds.

    Fishing and fish consumption are widely practiced among members of certain ethnocultural groups. Information assessment led them to ascribe high levels of consumption of locally caught sportfish to Montrealers of Asian origin and to hypothesize that their choices of species and fish organs differ from those of the majority group. An exploratory assessment of contaminant bioindicators reflective of St. Lawrence river fish consumption was conducted in late 1995 among nine Vietnamese and nine Bangladeshi Montreal sportfishers identified by community contacts. Vietnamese participants, six men and three women, were 27--70 years of age and had immigrated to Canada 3--20 years earlier. In contrast, the nine Bangladeshi males aged 28--41 years had been in Canada for 2--13 years. Bioindicator concentrations among Bangladeshi and Vietnamese participants are compared to those found for majority-community Montreal-area high-level consumers recruited on the St. Lawrence River during winter 1995.

  13. Seismic Vulnerability Assessment for Montreal -An Application of HAZUS-MH4

    2011-12-01

    Seismic loss estimation for Montreal, Canada is performed for a 2% in 50 years seismic hazard using the HAZUS-MH4 tool developed by US Federal Emergency Management. The software is manipulated to accept a Canadian setting for the Montreal study region, which includes 522 census tracts. The accuracy of loss estimations using HAZUS is dependent on the quality and quantity of data collection and preparation. The data collected for Montreal study region comprise: (1) the building inventory (2) hazard maps regarding soil amplification, liquefaction, and landslides (3) population distribution at three different times of the day (4) census demographic information and (5) synthetic ground motion contour maps using three different ground motion prediction equations. All these data are prepared and assembled into geodatabases that are compatible with the HAZUS software. The study estimated that roughly 5% of the building stock would be damaged with direct economic losses evaluated at 1.4 billion dollars for a scenario corresponding to the 2% in 50 years scenario. The maximum number of casualties associated with this scenario corresponds to a time of occurrence of 2pm and would result in approximately 500 people being injured. Epistemic uncertainty was considered by obtaining damage estimates for three attenuation functions that were developed for Eastern North America. The results indicate that loss estimates are highly sensitive to the choice of the attenuation function and suggests that epistemic uncertainty should be considered both for the definition of the hazard function and in loss estimation methodologies. The next steps in the study should be to increase the size of the survey area to the Greater Montreal which includes more than 3 million inhabitants and to perform more targeted studies for critical areas such as downtown Montreal, and the south-eastern tip of Montreal. The current study was performed mainly for the built environment; the next phase will need to

    Having in perspective the slight representativeness of students, from Haitian background, from the most unprivileged sections of the great region of Montreal in the scientific fields in High School and in the choices of career, this study intends to examine the effect of the individual characteristics as well as the associated factors related to the familial, scholastic, socio-economic, and cultural environment upon the attitudes of those students toward sciences. The analysis of the datum is based on the results of a questionnaire focusing on the socio-demographic profile of a group of students from fourth and fifth year attending two multiethnic High Schools of the North-Crown of Montreal as well as on the interviews with fifteen of those students who are from a haitian background. There were also interviews with some parents, a member of a community organism, some staff members of some schools as well as some Haitian-Quebecer professionals and scientists, in order to have a critical viewpoint upon the different positions expressed by the fifteen students. The Bronfenbrenner's ecosystemic model (1979, 1986) has been used as scope of reference allowing to draw the prominent aspects from the attitudes toward science in the students, from haitian background. The synthesis of ideas expressed by different interviewee reveals the existence of a environment not much enhancing the value of sciences around of students, from Haitian background. The socio-economic conditions, the familial practices, the ethnocultural status as well as some individual representations of sciences contribute to create and maintain some attitudes very little committed to sciences in those students. The study shows how much it is urgent to demystify the sciences by breaking with some stereotypes that prevent some categories of students from acceding to sciences. It also commands to politicians, concerning education, to be more open to ethnocultural differences and to explore some dynamic ways in

    success in getting a job as well as in developing some recovery effects. Accès-Cible SMT located in Montreal (Quebec, Canada) is also an interesting "hybrid" program since people with severe mental disorders can be supported by a counsellor, with a short period of training (a 28-week program with 6 steps) before integrating the regular labor market. The philosophy of Accès-Cible SMT is to consider their clients as normal persons more than as patients, and its objective is mainly to restore confidence and self-esteem of the person by putting emphasis on their professional skills. Meetings in groups, practicums in the workplace, and the utilization of job search strategies are essential ingredients of Accès-Cible SMT, which are also efficient tools to develop a better empowerment of the person. Indeed, the common ingredients/elements of these two vocational services, Messidor and Accès-Cible SMT, seem to be the development of empowerment for people with severe mental disorders. The scientific literature supports that empowerment is one of the key factors of recovery for people with a mental illness, a recovery process that can be illustrated by their work integration in the regular labor market as a final goal.

    Language-based differences in unintentional injury are poorly understood, despite the importance of language as a determinant of health. This study assessed inequalities in unintentional injury mortality between Francophones and Anglophones of Quebec, Canada. We calculated age-standardised rates of death by period, region, residential deprivation and cause of injury, and estimated rate ratios for Francophones relative to Anglophones. Francophones had higher unintentional injury mortality rates than Anglophones. Inequalities decreased over time for men, but rates remained 50% higher for Francophones at the end of the study period. Rates were stable for women, but were 30% higher for Francophones compared with Anglophones. Inequalities were larger at age 15-44 years, in urban areas, and for MVCs. Better understanding of risk factors for MVCs may benefit injury prevention in Quebec. Language-based differences in injury mortality warrant attention in other multilingual populations, especially across different demographic, temporal, regional and cause-of-injury groups.

    The government of Quebec (Canada) is poised to adopt a proposition to legalize euthanasia in the form of "Medical Aid in Dying," which presents a new option for end-of-life care. This proposition arouses concerns among palliative care providers. The aim of this article is to provide a palliative care perspective on Quebec's proposition to legalize euthanasia. Based on the epistemological and methodological framework of critical theory, the following three questions are raised: First, in Quebec's current state of the law, is it possible to relieve the suffering of end-of-life patients? Second, can the Quebec proposition to legalize euthanasia in specific circumstances be harmful? Third, is the Quebec proposition on euthanasia compatible with palliative care and social values? In conclusion, recommendations and alternatives to the current Quebec proposition are suggested. PMID:24125960

    An epizootic of bovine mastitis caused by a nontuberculous mycobacterial agent occurred in a large Quebec dairy herd. This mastitis problem was characterized by the occurrence of a high number of cows with severely inflamed, indurated and therapeutically incurable quarters. Routine diagnostic laboratory methods yielded negative cultural findings. Approximately 40% of the milking cows developed chronic mastitis. Poor sanitation, improper milking procedures and a faulty milking system prevailed at that time. PMID:17422316

    A US court has denied a request that it reconsider a decision upholding Hydro-Quebec's $4 billion sale of 340 MW to 16 Vermont utilities. The Vermont Supreme Court issued the decision in October, rejecting arguments that the contract would result in construction of Hydro-Quebec's giant Grande Baleine (Great Whale) hydroelectric development, flooding Creek Indian lands and harming waterfowl. The Vermont Public Service Board endorsed the 340-MW sale - the continuation of a previous sale - to 24 utilities in 1990, but rejected sale of an additional 110 MW without more proof that the power is needed and that its generation would not cause undue environmental damage. Since 1990, one utility merged with another, and seven withdrew from the contract, leaving 16 buyers. The New England Coalition for Energy Efficiency and the Environment and the Grand Council of the Cree appealed the Public Service Board approval. The high court agreed with the Public Service Board that the 340-MW purchase - a fraction of Hydro-Quebec's total 24,000-MW output - is a continuation of an earlier purchase and that no new construction at James Bay is necessary to supply the power. That finding undercut arguments about Grande Baleine's effects on the Cree.

    Background  The threat of 2009 pandemic influenza A (H1N1) is still causing widespread public concern. A comprehensive understanding of the epidemiology of 1918 pandemic influenza commonly referred to as the Spanish flu may be helpful in offering insight into control strategies for the new pandemic. Objective  We explore how the preparedness for a pandemic at the community and individual level impacts the spread of the virus by comparing the transmissibility of the 1918 Spanish flu in two Canadian cities: Montreal and Winnipeg, bearing in mind that each pandemic is unique and the current one may not follow the pattern of the 1918 outbreak. Methods  The historical epidemiological data obtained for Montreal and Winnipeg in Canada is analyzed to estimate the basic reproduction number which is the most important summary measure of transmission potential of the pandemic. Results  The transmissibility of the 1918 pandemic influenza virus in Winnipeg in the fall of 1918 was found to be much lower than in Montreal based on the estimated reproduction number obtained assuming different serial intervals which are the time between onsets of symptoms in an index case and a secondary case. Conclusion  The early preparedness and public health control measures could suggest an explanation for the fact that the number of secondary cases generated by a primary case was significantly reduced in Winnipeg comparing to it in Montreal.

  12. A cost-benefit/cost-effectiveness analysis of proposed supervised injection facilities in Montreal, Canada

    PubMed Central

    2013-01-01

    Background This paper will determine whether expanding Insite (North America’s first and only supervised injection facility) to more locations in Canada such as Montreal, cost less than the health care consequences of not having such expanded programs for injection drug users. Methods By analyzing secondary data gathered in 2012, this paper relies on mathematical models to estimate the number of new HIV and Hepatitis C (HCV) infections prevented as a result of additional SIF locations in Montreal. Results With very conservative estimates, it is predicted that the addition of each supervised injection facility (up-to a maximum of three) in Montreal will on average prevent 11 cases of HIV and 65 cases of HCV each year. As a result, there is a net cost saving of CDN$0.686 million (HIV) and CDN$0.8 million (HCV) for each additional supervised injection site each year. This translates into a net average benefit-cost ratio of 1.21: 1 for both HIV and HCV. Conclusions Funding supervised injection facilities in Montreal appears to be an efficient and effective use of financial resources in the public health domain. PMID:23837814

    Introduction Emergency departments are important safety nets for people who live in rural areas. Moreover, a serious problem in access to healthcare services has emerged in these regions. The challenges of providing access to quality rural emergency care include recruitment and retention issues, lack of advanced imagery technology, lack of specialist support and the heavy reliance on ambulance transport over great distances. The Quebec Ministry of Health and Social Services published a new version of the Emergency Department Management Guide, a document designed to improve the emergency department management and to humanise emergency department care and services. In particular, the Guide recommends solutions to problems that plague rural emergency departments. Unfortunately, no studies have evaluated the implementation of the proposed recommendations. Methods and analysis To develop a comprehensive portrait of all rural emergency departments in Quebec, data will be gathered from databases at the Quebec Ministry of Health and Social Services, the Quebec Trauma Registry and from emergency departments and ambulance services managers. Statistics Canada data will be used to describe populations and rural regions. To evaluate the use of the 2006 Emergency Department Management Guide and the implementation of its various recommendations, an online survey and a phone interview will be administered to emergency department managers. Two online surveys will evaluate quality of work life among physicians and nurses working at rural emergency departments. Quality-of-care indicators will be collected from databases and patient medical files. Data will be analysed using statistical (descriptive and inferential) procedures. Ethics and dissemination This protocol has been approved by the CSSS Alphonse–Desjardins research ethics committee (Project MP-HDL-1213-011). The results will be published in peer-reviewed scientific journals and presented at one or more scientific

    For years, studies of founder populations and genetic isolates represented the mainstream of genetic mapping in the effort to target genetic defects causing Mendelian disorders. The genetic homogeneity of such populations as well as relatively homogeneous environmental exposures were also seen as primary advantages in studies of genetic susceptibility loci that underlie complex diseases. European colonization of the St-Lawrence Valley by a small number of settlers, mainly from France, resulted in a founder effect reflected by the appearance of a number of population-specific disease-causing mutations in Quebec. The purported genetic homogeneity of this population was recently challenged by genealogical and genetic analyses. We studied one of the contributing factors to genetic heterogeneity, early Native American admixture that was never investigated in this population before. Consistent admixture estimates, in the order of one per cent, were obtained from genome-wide autosomal data using the ADMIXTURE and HAPMIX software, as well as with the fastIBD software evaluating the degree of the identity-by-descent between Quebec individuals and Native American populations. These genomic results correlated well with the genealogical estimates. Correlations are imperfect most likely because of incomplete records of Native founders' origin in genealogical data. Although the overall degree of admixture is modest, it contributed to the enrichment of the population diversity and to its demographic stratification. Because admixture greatly varies among regions of Quebec and among individuals, it could have significantly affected the homogeneity of the population, which is of importance in mapping studies, especially when rare genetic susceptibility variants are in play.

  8. Interdisciplinary collaboration within Quebec Community Health Care Centres.

    Central to the success of many recent health system reforms is the implementation of new primary health care delivery models. The central characteristic common to these new models usually emphasises interdisciplinary collaboration. Using empirical research, this paper studies interdisciplinary collaboration among various groups of professionals within an original Canadian primary health care delivery model, the Quebec Community Health Care Centres (CCHCs). The entire population of more than 150 CHCCs have been surveyed. The goals of this study are (1) to measure the achieved intensity of inter-professional collaboration among Quebec CHCCs, and (2) to identify the organisational and professional factors fostering or limiting interdisciplinary collaboration. The results show that Quebec CHCCs have reached modest results in achieving interdisciplinary collaboration especially since interdisciplinary collaboration is a central objective that has been pursued for more than 25 years. This study demonstrates that the main factors associated with interdisciplinary collaboration are closely linked to work group internal dynamics. Interdisciplinary collaboration is linked to the simultaneous and antagonistic effect of some central intragroup process factors. Conflicting values and beliefs are present that both enhance and limit interdisciplinary collaboration. The presence of conflicting stimuli seriously undermines the strength of the CHCC work group's shared beliefs and strongly limits interdisciplinary collaboration. The results also stress the importance of administrative formalisation initiatives to enhance collaboration among different professions. The efficacy of formalisation in this context is based on its capacity to offer an articulated and operative interdisciplinary framework that can generate a counteractive effect to the traditional professional framework. It offers concrete rules that help align the work group beliefs with interdisciplinary values. The

    This study aimed at determining the role of proximity to specific types of green spaces (GSes) as well as their spatial location in the relationship with the most morbid cardiovascular diseases (CVD) and diabetes. We measured the accessibility to various types of GS and used a cross-sectional approach at census Dissemination Area (DA) levels in the Montreal and Quebec City metropolitan zones for the period 2006-2011. Poisson and negative binomial regression models were fitted to quantify the relationship between distances to specific types of GS and CVD morbidity as well as some risk factors (diabetes and hypertension) while controlling for several social and environmental confounders. GSes that have sports facilities showed a significant relationship to cerebrovascular diseases: the most distant population had an 11% higher prevalence rate ratio (PRR) compared to the nearest, as well as higher diabetes risk (PRR 9%) than the nearest. However, the overall model performance and the understanding of the role of GSes with sport facilities may be substantially achieved with lifestyle factors. Significantly higher prevalence of diabetes and cerebrovascular diseases as well as lower access to GSes equipped with sports facilities were found in suburban areas. GSes can advantageously be used to prevent some CVDs and their risk factors, but there may be a need to reconsider their types and location. PMID:27089356

    Chlorine- and bromine-containing ozone-depleting substances (ODSs) are controlled by the 1987 Montreal Protocol. In consequence, atmospheric equivalent chlorine peaked in 1993 and has been declining slowly since then. Consistent with this, models project a gradual increase in stratospheric ozone with the Antarctic ozone hole expected to disappear by ∼2050. However, we show that by 2013 the Montreal Protocol had already achieved significant benefits for the ozone layer. Using a 3D atmospheric chemistry transport model, we demonstrate that much larger ozone depletion than observed has been avoided by the protocol, with beneficial impacts on surface ultraviolet. A deep Arctic ozone hole, with column values <120 DU, would have occurred given meteorological conditions in 2011. The Antarctic ozone hole would have grown in size by 40% by 2013, with enhanced loss at subpolar latitudes. The decline over northern hemisphere middle latitudes would have continued, more than doubling to ∼15% by 2013. PMID:26011106

    Hydrofluorocarbons (HFCs) are used as substitutes for ozone-depleting substances that are being phased out globally under Montreal Protocol regulations. New global scenarios of HFC emissions reach 4.0-5.3 GtCO2-eq yr-1 in 2050, which corresponds to a projected growth from 2015 to 2050 which is 9% to 29% of that for CO2 over the same time period. New baseline scenarios are formulated for 10 HFC compounds, 11 geographic regions, and 13 use categories. These projections are the first to comprehensively assess production and consumption of individual HFCs in multiple use sectors and geographic regions with emission estimates constrained by atmospheric observations. In 2050, in percent of global HFC emissions, China (~30%), India and the rest of Asia (~25%), Middle East and northern Africa (~10%), and USA (~10%) are the principal source regions; and refrigeration and stationary air conditioning are the major use sectors. National regulations to limit HFC use have been adopted recently in the European Union, Japan and USA, and four proposals have been submitted in 2015 to amend the Montreal Protocol to substantially reduce growth in HFC use. Calculated baseline emissions are reduced by 90% in 2050 by implementing the North America Montreal Protocol amendment proposal. Global adoption of technologies required to meet national regulations would be sufficient to reduce 2050 baseline HFC consumption by more than 50% of that achieved with the North America proposal for most developed and developing countries. The new HFC scenarios and effects of national regulations and Montreal Protocol amendment proposals will be presented.

  17. A post-Kyoto partner: Considering the Montreal Protocol as a tool to manage nitrous oxide

    While nitrous oxide (N2O) was recently identified as the largest remaining anthropogenic threat to the stratospheric ozone layer, it is currently regulated under the 1997 Kyoto Protocol due to its simultaneous ability to warm the climate. The threat N2O poses to the stratospheric ozone layer, coupled with the uncertain future of the international climate regime, motivates our exploration of issues that could be relevant to the Parties to the 1987 Montreal Protocol if they decide to take measures to manage N2O in the future. There are clear legal avenues for the Montreal Protocol and its parent treaty, the 1985 Vienna Convention, to regulate N2O, as well as several ways to share authority with the existing and future international climate treaties. N2O mitigation strategies exist to address its most significant anthropogenic sources, including agriculture, where behavioral practices and new technologies could contribute significantly to mitigation efforts. Existing policies managing N2O and other forms of reactive nitrogen could be harnessed and built upon by the Montreal Protocol's existing bodies to implement N2O controls. Given the tight coupling of the nitrogen cycle, such controls would likely simultaneously reduce emissions of reactive nitrogen and hence have co-benefits for ecosystems and public health. Nevertheless, there are at least three major regulatory challenges that are unique and central to N2O control: food security, equity, and the nitrogen cascade. The possible inclusion of N2O in the Montreal Protocol need not be viewed as a sign of the Kyoto Protocol's failure to adequately deal with climate change, given the complexity of the issue. Rather, it could represent an additional tool in the field of sustainable development diplomacy.lt;img border=0 src="images/B43K-06_B.jpg">

    The Montreal Neighbourhood Networks and Healthy Aging study was established: (i) to assess the added value in using formal network methods and instruments to measure social capital and its relationship to health; (ii) to determine whether older adults are more vulnerable to the effects of network and neighbourhood environments; and (iii) to examine longitudinally the relationship between social capital and health among adults in Montreal, Canada. The MoNNET-HA cohort consists of men and women aged 25 years and older, residing in the Montreal Metropolitan Area (MMA). Participants were recruited using a random stratified cluster sampling design with oversampling of adults older than 65 years. Initial MoNNET-HA study participants (n = 2707) were recruited for telephone interviews in the summer of 2008. Since 2008, participants were interviewed in the autumn of 2010 and the winter of 2013/2014. Data currently fall into five categories: (i) social network and social capital; (ii) psychosocial and psychological; (ii) socio-demographic and socioeconomic; (iv) health behaviours and conditions; and (v) neighbourhood environmental characteristics. Healthcare utilization data will be available for a subsample of participants. Upon funding, future work will measure anthropometric and metabolic health directly. Based on agreements with participants, external researchers should request access to data via collaborations with the study group. PMID:24984955

    Radio tracking via satellite was initiated to study the year-round movements of Golden Eagles(Aquila chrysaetosc anadensis) breeding on the east coast of Hudson Bay, Quebec. In June and August 1992, six Golden Eagles(five adults and one juvenile) were marked, three of which completed their year-round movements. The eagles left their breeding area in mid- to late October and migrated to known wintering areas in the eastern United States. They used different routes but each followed the same general path during fall and spring migrations which lasted between 26 and 40 days,and 25 and 51 days, respectively. Eagles wintered from 93 to 135 days in areas located 1,650 to 3,000 km south of their breeding territory. In spring 1993, satellite telemetry located the eagles in their former breeding territory in late March, mid-April and early May. This study confirms previous suggestion that some breeding Golden Eagles wintering in eastern United States come from northern Quebec and describes the first successful tracking of the complete yearly migration cycle of a bird of prey.

  20. Quebec mental health services networks: models and implementation

    Abstract Purpose In the transformation of health care systems, the introduction of integrated service networks is considered to be one of the main solutions for enhancing efficiency. In the last few years, a wealth of literature has emerged on the topic of services integration. However, the question of how integrated service networks should be modelled to suit different implementation contexts has barely been touched. To fill that gap, this article presents four models for the organization of mental health integrated networks. Data sources The proposed models are drawn from three recently published studies on mental health integrated services in the province of Quebec (Canada) with the author as principal investigator. Description Following an explanation of the concept of integrated service network and a description of the Quebec context for mental health networks, the models, applicable in all settings: rural, urban or semi-urban, and metropolitan, and summarized in four figures, are presented. Discussion and conclusion To apply the models successfully, the necessity of rallying all the actors of a system, from the strategic, tactical and operational levels, according to the type of integration involved: functional/administrative, clinical and physician-system is highlighted. The importance of formalizing activities among organizations and actors in a network and reinforcing the governing mechanisms at the local level is also underlined. Finally, a number of integration strategies and key conditions of success to operationalize integrated service networks are suggested. PMID:16773157

    Awareness of groundwater protection has increased substantially in recent decades. In the Province of Quebec, Canada, the Groundwater Catchment Regulation (GWCR) was promulgated in 2002 to protect water quality in public wells. The goal of the present study was to document groundwater protection in the context of emerging regulations and identify factors explaining the propensity of municipalities applying protection strategies. Two types of information were used in this study: data from a questionnaire-based survey conducted among 665 municipalities in the Province of Quebec and complementary information gathered from various sources. Data from the survey revealed that fewer than half of the municipalities have been able to comply with the GWCR, mainly because of financial limitations. Also, close to half of the municipalities have either identified or are expecting land use conflicts to arise between protection areas required by the GWCR and other land usage, with agriculture being the main conflicting activity. Multivariate logistic regression models served to identify factors explaining the likelihood of municipalities to take groundwater protection measures. Those factors were municipality revenue, history of water contamination in distribution systems, land use near wellheads, location of municipalities within a provincial priority watershed and the importance of groundwater use in a region. Results of the study may prove helpful for government authorities in better understanding the groundwater protection issue and in implementing strategies that improve the ability of municipalities to protect groundwater.

    This paper studies the urban heat island in Quebec City and its suburbs on one summer night. The region under study covers an area of 20 km by 20 km which streches from lake Saint-Charles on the north to Levis on the south and from the western suburb of Cap-Rouge to Beauport on the east. The total population of the region is about 400 000. On August 22, 1979 from 22:00 to 23:30 EDT, 109 measurements of wet- and dry-bulb temperatures were taken at preselected points. On that day, a large high pressure system gave clear skies to central Quebec while Quebec City Airport recorded a maximum temperature of 23 °C. The average wind measured at Duberger meteorological tower between 6 and 121 m above ground was 1.8 m s-1 at 22:00 EDT and 0.9 m s-1 at 23:30 EDT. Additional data were obtained from three thermographs installed at strategic points and five regular climatological stations, which were used to estimate cooling rates. During the period of measurement, the cooling rate averaged over the eight reference points was about 0.7 °C h-1. However, the maximum cooling rate, which occured earlier, ranged from 2.2 °C h-1 at Duberger to 4.4 °C h-1 at Courville-de-Poissy. No relation seems to exist, in our case, between the maximum cooling rate and the heat island spatial structure. Comparison of these results with the ones given by Oke et al. (1972) shows that the eight stations behaved more like rural stations than urban ones. The temperature gradient measured between the center of old Quebec City and the suburbs averaged 6 °C while it was 9 °C for the coldest spot. Clo units were used to characterize the microclimates prevailing on the region for that night; 1 clo would be sufficient for comfort downtown while 1.5 clo is needed in the coldest spot for a slowly walking person. Large open areas like parks or the Laval University campus had a definite effect on temperature. The humidity was calculated for each point using standard psychrometric tables; no significant

    In the late 1960s, Quebec demonstrated its willingness to influence migration by creating a Ministry of Immigration. The goal of the Ministry changed over the course of a decade from assuring harmonious integration of immigrants to obtaining a greater role in recruitment and selection as well as in reception and establishment. In the early 1970s the Canadian government undertook a significant revision of its immigration policies. The most significant change was probably the requirement of an annual estimate of the number of immigrants judged opportune to admit during a particular time period. to be preceded by consultations with the provinces concerning demographic needs and the labor market. A 1978 agreement between Quebec and the Canadian government gave Quebec a greater role in immigrant selection and recruitment, and in effect allowed it to develop its own immigration policy. Ability to absorb potential immigrants became the primary criterion in setting quotas for Quebec. The approach of the federal government has not changed greatly since the new policy came into use. The extent of annual net immigration judged desirable has changed from about 75,000 persons initially to about 55,000 more recently. The federal government has always viewed immigration as a possible solution to labor market problems, but estimates of manpower needs became very volatile in the late 1970s with the general rise in rates of unemployment, and survey results lost importance as a source of guidance. The government estimated that 20 to 25 thousand immigrants selected to fill specific manpower needs could be accomodated annually in the 1980s, but the collapse of the labor market following the economic crisis caused a downward revision in estimates for 1982-83 to 8000 to 10,000 workers with jobs already in hand. In order to participate in planning of immigration, Quebec had to develop a research program desinged to identify its capacity to absorb immigrants each year. The 1st step was to

    This paper describes research and development activities at Hydro-Quebec over the last ten years for improving the efficiency of distribution transformers in Quebec. A shell-type (wound-core) design making optimum use of the properties of amorphous metals (Metglas TCA formerly known as Metglas 2605s-2, Allied Signal Inc., Morristown, NJ) was adopted. Dry and oil-cooled, amorphous-core transformer prototypes were built. The joint research and development project was initiated with Transformateurs Ferranti-Packard Ltee, a company of Rolls-Royce Industries Canada Inc., to build and test a few units of high performance transformers on the Hydro-Quebec power system.

    Data on anaphylaxis cases in pre-hospital settings is limited. As part of the Cross Canada Anaphylaxis Registry (C-CARE), we assessed anaphylaxis cases managed by paramedics in Outaouais, Quebec. A software program was developed to prospectively record demographic and clinical characteristics as well as management of cases meeting the definition of the anaphylaxis. Univariate and multivariate logistic regressions were compared to assess factors associated with severity of reactions and epinephrine use. Among 33,788 ambulance calls of which 23,486 required transport, 104 anaphylaxis cases were identified (anaphylaxis rate of 0.31% [95%CI, 0.25%, 0.37%] among all ambulance calls and 0.44% [95%CI, 0.36%, 0.54%] among those requiring transport). The median age was 46.8 years and 41.3% were males. The common triggers included food (32.7% [95%CI, 24.0%, 42.7%]), drugs (24.0% [16.4%, 33.6%]), and venom (17.3% [10.8%, 26.2%]). Among all reactions, 37.5% (95%CI, 28.4%, 47.6%) were severe. Epinephrine was not administered in 35.6% (95%CI, 26.6%, 45.6%) of all cases. Males were more likely to have severe reactions (Odds ratio [OR]: 2.50 [95%CI, 1.03, 6.01]). Venom-induced reactions and severe anaphylaxis were more likely to be managed with epinephrine (OR: 6.9 [95%CI, 1.3, 35.3] and 4.2 [95%CI, 1.5, 12.0], respectively). This is the first prospective study evaluating anaphylaxis managed by paramedics. Anaphylaxis accounts for a substantial proportion of the cases managed by paramedics in Outaouais, Quebec and exceeds prior reports of the proportion of Quebec emergency room visits attributed to anaphylaxis. Although guidelines recommend prompt use of epinephrine for all cases of anaphylaxis, more than a third of cases did not receive epinephrine. It is crucial to develop educational programs targeting paramedics to promote the use of epinephrine in all cases of anaphylaxis regardless of the specific trigger. PMID:26734462

    Black carbon (BC), the solid carbonaceous residue of incomplete combustion, is a major by-product of wildfires in Quebec black spruce forests. Because of its estimated recalcitrance, it is considered a valuable pool in the global carbon cycle. However, BC characteristics, and more specifically its resistance to degradation depend on its conditions of formation. The objective of this study was to characterize BC chemical and physical properties under varying fire severities in order to assess its potential for recalcitrance as a passive carbon pool. Fresh BC samples from the forest floor were collected in 2010 from Quebec black spruce forests stands that had burnt 3-5 years prior. Fire severity was assessed at each sampling location and a total of 33 samples were selected to cover the range of severity encountered in these burnt forests. Samples were further analyzed for aromaticity and porosity using elemental and proximate analyses, solid-state 13C nuclear magnetic resonance (NMR) spectroscopy, scanning electron microscopy (SEM) and surface area (SA) analysis. They were then compared to BC samples produced under controlled conditions in the laboratory (lab-BC). The 13C NMR spectra of the BC collected on low fire severity sites showed a distribution of total intensity between the different spectral regions very similar to those of unburnt fuels. They were generally dominated by a peak at 74 ppm indicative of cellulose. On the other hand, 13C NMR spectra obtained for BC from high fire severity sites were dominated by peaks from aromatic carbons. When compared to the lab-BC NMR spectra, we concluded that the temperature of formation for the 33 analyzed samples ranged between 75°C and 250°C and that pyrolysis conditions prevailed, which points towards BC formation by a smouldering fire. Atomic ratio values (H/C = [1.36-0.77]; O/C = [0.75-0.30]) decreased with increasing fire severity and were in agreement with the results from 13C NMR spectroscopy. Finally, the

    The Potsdam sandstone aquifer of Cambrian age straddles southern Quebec and northern New York in a region known for its abundant and good quality groundwater, a resource that recently has been coveted by several bottling companies. The potential conflicts and concerns of the mainly rural and groundwater dependent population about the possible overuse of this resource has led the Quebec Ministry of Environment, Geological Survey of Canada and the U. S. Geological Survey to jointly carry out a transboundary hydrogeological study of the Potsdam sandstone aquifer. The Potsdam sandstone aquifer consists of a lower unit of arkose and conglomerate and an upper unit of well-cemented quartz arenite. The thickness of the regional aquifer ranges from nil at the base of Adirondacks to more than 500 m near the St. Lawrence River. Glacial till, littoral sand and gravel, and marine silt and clay discontinuously overlie the aquifer. The aquifer's water budget is characterized by low rates of surface runoff and high rates of infiltration and sub-surface runoff. Major recharge areas are present at higher altitudes near and to the south of the border. Strong downward hydraulic gradients in these areas result in cascading water and water-level depths of more than 30 m in deep wells. Bedding in the Potsdam sandstone is gently dipping with fractures along sub-horizontal bedding planes forming major flow conduits. Bedrock folds and faults, mainly developed by east-west compression during the Appalachian orogenies, locally complicates aquifer geometry and groundwater flow. Hydraulic tests (pump, slug, flowmeter and straddle packer) indicate similar horizontal transmissivities in the lower and upper aquifer units. However, differences in lithology and structure of the aquifer units impose some apparent differences in hydraulic properties and groundwater flow patterns. In the lower unit, regional flow appears to be sustained by a limited number of laterally extensive bedding-plane fractures

    The basin of the Lièvre River (9542 km2), Quebec, Canada, has a water system consisting of three high-capacity reservoirs. During floods, the reservoir management gives priority to flood control and hydropower generation but also tries to respect constraints associated with environmental issues. Nevertheless, the basin is subject to floods, raising the need for improved water system management tools. Since these reservoirs are also part of the Ottawa River system, the main tributary of the St. Lawrence River, reservoirs of the Lièvre River also impact floods and low flows in the Montreal Archipel, through their influence on streamflows in the Mille-Îles and Des Prairies Rivers. Low flow is an important issue in this area since a large population relies on the streamflow of the Mille-Îles River for freshwater. The effect of an anticipated increase of extreme meteorological events as a result of climate change makes the evaluation of water system capacity of the Lièvre River even more important to reduce the impacts of such hydrometeorological events. This kind of optimization problem has been studied in the past and there are many approaches to obtain, or at least to find an optimal solution, such as linear programming, nonlinear programming and dynamic programming. The later is widely used, but difficult to apply to systems with more than three reservoirs since computational time exponentially increases as the number of state variables increases. One of the goals of this study is to eventually extend the water system management to the entire Ottawa River watershed, which includes more than 40 reservoirs. A nonlinear programming approach using an interior-point algorithm has therefore been chosen for the Lievre reservoir system. Constraints related to the Montreal Archipel constitute a further challenge as the many reservoirs on the Ottawa River watershed upstream from the Lièvre River are managed by various owners. It is therefore difficult to know with

    OBJECTIVE: To determine whether the noise from low-level flights over Labrador and Quebec is harmful to human health. DATA SOURCE AND SELECTION: Search of MEDLINE for articles on the effect of noise, particularly impulse noise associated with low-level flights, and a search of the references from identified articles. DATA SYNTHESIS: The noise levels from low-level flights could affect hearing acuity. However, the more important consequences appear to be stress-mediated physiologic effects, especially cardiovascular ones, and psychologic distress, particularly in children. Subjective perception of control over the noise has been found to mitigate some physiologic effects. CONCLUSION: There is sufficient evidence to show that the noise from low-level flights is harmful to human health. PMID:2007238

    This paper analyzes the debates surrounding the privatization of health services financing in Quebec. The objective is to clarify policy-making processes with regard to this important issue and, more generally, to provide a realistic understanding of health-related policy processes in Canada. The analysis is based on a large and continuous sample of mass media and National Assembly debates on the question during the four-and-a-half years following the Chaoulli ruling of the Supreme Court of Canada. These data are used to test four hypotheses about relationships among the types of political actors involved, their policy preferences, the rhetoric they use and the anticipated policy effects they assert. The results are applied to a discussion of questions about the factors that influence the effectiveness of political communication. PMID:23968604

    The purpose of our research was to identify shrub species growing in southern Quebec that inhibit ecological succession in power-line corridors. Results are presented in three parts. First, clonal characteristics that allowed the establishment of stable communities were identified. Second, successional vector analysis identified those species that have the potential to inhibit succession. In poorly drained sites those species were Cornus stolonifera, C. obliqua, Salix petiolaris, and Spiraea alba. In well-drained sites, those species were Zanthoxylum americanum, Rubus idaeus, Spiraea alba, Rhus typhina, and Thuja occidentalis. Third, analysis of variance showed that there is a significantly larger number of tree seedlings found in adjacent herbaceous communities than found under the dense cover of Cornus stolonifera, C. obliqua, Salix petiolaris, Spiraea alba, Rhus typhina, Rubus idaeus, Thuya occidentalis, and Zanthoxylum americanum. These results indicate that the planting of selected shrub species could, through biological control, delay reforestation.

    Soon, physicians across Canada will be permitted to assist patients in dying, provided certain conditions are met. Physicians in the province of Quebec can already provide this service since December 10, 2015. While Quebec has been studying the question of legislating medical aid in dying since 2009, the rest of the country must come up with legislation on this issue within the next few months. This article suggests that other Canadian jurisdictions, federally and provincially/territorially, may find inspiration in the extensive work done in Quebec leading to its end-of-life legislation, including on the issues of identifying proper safeguards to protect vulnerable people and eligibility criteria that could be put in place in these jurisdictions. The Quebec model could be particularly useful in regard to the approach to balancing physicians' rights of conscience with patients' constitutional right to access medical aid in dying.

    This essay seeks to rationalize and explain the evolution of medical rhetoric in Cité libre by looking at trends in the journal's use of tropes of illness and disease. Through a combination of broad content analysis and close readings, it contrasts how individual metaphors create the impression of a sickening nation and the manner in which these metaphors collectively, albeit paradoxically, act as a national allegory of cure for mid-twentieth-century Quebec's social ills in general, and specifically for its pathological inferiority complex. By examining how the journal uses medical metaphors and specifically how the writers employed the trope of the body politic to illustrate Quebec's national failings, the essay demonstrates how Quebec challenges the rhetorical stability of the age-old metaphor as it attempts to solve, but also creates, problems within Quebec's articulation of its own nationhood.

  15. Recent Increases in Stratospheric HCl: Stratospheric Dynamics versus the Montreal Protocol

    NASA Astrophysics Data System (ADS)

    2014-05-01

    Long-lived chlorine-containing source gases, such as chlorofluorocarbons (CFCs), are transported into the stratosphere where they decompose and cause ozone depletion. Increases in chlorine during the 1970s-1990s resulted in long-term ozone decreases, especially in the polar regions. Following the implementation of the Montreal Protocol, the near-surface chlorine loading was observed to peak in 1993 and, since then, to decrease in line with expectations. After release from source gases in the stratosphere, chlorine mainly forms the reservoir HCl, providing an alternative method for monitoring the progress of the Montreal Protocol. A maximum in stratospheric HCl was observed around 1996, followed by decay at a rate close to 1%/year, consistent with the tropospheric chlorine peak and known transport timescales. However, we will present total column observations from ground-based FTIR instruments which show an unexpected and significant upturn in stratospheric HCl around 2007 in the northern hemisphere. Height-resolved observations from satellite instruments (HALOE, MLS, ACE) confirm this increase and show that it occurs in the lower stratosphere. These observations contrast with the ongoing monotonic decrease of near-surface chlorine source gases. Using 3-D model simulations (TOMCAT/SLIMCAT and KASIMA) we attribute this trend anomaly to a slowdown in the NH atmospheric circulation, causing air in the lower stratosphere to become more aged with a larger relative conversion of source gases to HCl. An important conclusion is that the Montreal Protocol is still on track and will still lead to long-term decreases in stratospheric chlorine. This dynamical variability could also significantly affect the evolution of stratospheric ozone and must be accounted for when searching for signs of ozone recovery.

  16. Variability and Uncertainty in Probabilistic Seismic Hazard Analysis for the Island of Montreal

    NASA Astrophysics Data System (ADS)

    Elkady, Ahmed Mohamed Ahmed

    The current seismic design process for structures in Montreal is based on the 2005 edition of the National Building Code of Canada (NBCC 2005) which is based on a hazard level corresponding to a probability of exceedence of 2% in 50 years. The code is based on the Uniform Hazard Spectrum (UHS) and deaggregation values obtained by Geological Survey of Canada (GSC) modified version of F-RISK software and were obtained by a process that did not formally consider epistemic uncertainty. Epistemic uncertainty is related to the uncertainty in model formulation. A seismological model consists of seismic sources (source geometry, source location, recurrence rate, magnitude distribution, and maximum magnitude) and a Ground-Motion Prediction Equation (GMPE). In general, and particularly Montreal, GMPEs are the main source of epistemic uncertainty with respect to other variables of seismological the model. The objective of this thesis is to use CRISIS software to investigate the effect of epistemic uncertainty on probabilistic seismic hazard analysis (PSHA) products like the UHS and deaggregation values by incorporating different new GMPEs. The epsilon "epsilon" parameter is also discussed which represents the departure of the target ground motion from that predicted by the GMPE as it is not very well documented in Eastern Canada. A method is proposed to calculate epsilon values for Montreal relative to a given GMPE and to calculate robust weighted modal epsilon values when epistemic uncertainty is considered. Epsilon values are commonly used in seismic performance evaluations for identifying design events and selecting ground motion records for vulnerability and liquefaction studies. A brief overview of record epsilons is also presented which accounts for the spectral shape of the ground motion time history is also presented.

    Introduction Rural emergency departments (EDs) are important safety nets for the 20% of Canadians who live there. A serious problem in access to health care services in these regions has emerged. However, there are considerable geographic disparities in access to trauma center in Canada. The main objective of this project was to compare access to local 24/7 support services in rural EDs in Quebec and Ontario as well as distances to Levels 1 and 2 trauma centers. Materials and Methods Rural EDs were identified through the Canadian Healthcare Association's Guide to Canadian Healthcare Facilities. We selected hospitals with 24/7 ED physician coverage and hospitalization beds that were located in rural communities. There were 26 rural EDs in Quebec and 62 in Ontario meeting these criteria. Data were collected from ministries of health, local health authorities, and ED statistics. Fisher’s exact test, the t-test or Wilcoxon-Mann-Whitney test, were performed to compare rural EDs of Quebec and Ontario. Results All selected EDs of Quebec and Ontario agreed to participate in the study. The number of EDs visits was higher in Quebec than in Ontario (19 322 ± 6 275 vs 13 446 ± 8 056, p = 0.0013). There were no significant differences between Quebec and Ontario’s local population and small town population density. Quebec’s EDs have better access to advance imaging services such as CT scanner (77% vs 15%, p < .0001) and most the consultant support and ICU (92% vs 31%, p < .0001). Finally, more than 40% of rural EDs in Quebec and Ontario are more than 300 km away from Levels 1 and 2 trauma centers. Conclusions Considering that Canada has a Universal health care system, the discrepancies between Quebec and Ontario in access to support services are intriguing. A nationwide study is justified to address this issue. PMID:25874948

    The authors interviewed first-generation Greek immigrant women in Montreal about nonspecific somatic symptoms. The concept of nevra (nerves), which was central to these discussions, was used to link environmental and psychosocial variables with distress and painful physical states. The authors discuss the cultural construction of female identity in Greece and analyze the negative effect of immigration on self-esteem, often manifested as attacks of nevra. Metaphorical concepts, such as nevra, can be used to improve physician understanding and to facilitate communication with, and enhance care of, immigrant patients. PMID:21234036

    This analysis examined references to foods mentioned in elementary school textbooks used in Montreal English schools. A study of 58 language arts and mathematics textbooks used in grades one-six revealed 4,391 references to foods in words and pictures. A large proportion of the references were to sugar-rich foods. Eating with peers was depicted more frequently than eating with family, while a surprising number of children were depicted consuming their food alone in texts used in grades one-three. Results suggest that, because unintended information may influence children's nutritional habits, more attention should be directed at concomitant messages in elementary school textbooks.

    An evaluation of lateral landfill gas migration was carried out at the Saint-Michel Environmental Complex in Montreal, City of Montreal Landfill Site, Canada, between 2003 and 2005. Biogas concentration measurements and gas-pumping tests were conducted in multilevel wells installed in the backfilled overburden beside the landfill site. A migration event recorded in autumn 2004 during the maintenance shutdown of the extraction system was simulated using TOUGH-LGM software. Eleven high-density instantaneous surface monitoring (ISM) surveys of methane were conducted on the test site. Gas fluxes were calculated by geostatistical analyses of ISM data correlated to dynamic flux chamber measurements. Variograms using normal transformed data showed good structure, and kriged estimates were much better than inverse distance weighting, due to highly skewed data. Measurement-based estimates of yearly off-site surface emissions were two orders of magnitude higher than modelled advective lateral methane flux. Nucleodensimeter measurements of the porosity were abnormally high, indicating that the backfill was poorly compacted. Kriged porosity maps correlated well with emission maps and areas with vegetation damage. Pumping tests analysis revealed that vertical permeability was higher than radial permeability. All results suggest that most of the lateral migration and consequent emissions to the atmosphere were due to the existence of preferential flow paths through macropores. In December 2006, two passively vented trenches were constructed on the test site. They were successful in countering lateral migration. PMID:18578151

    The release of man-made ozone depleting substances (ODS, including chlorofluorocarbons and halons) into the atmosphere has led to a near-linear increase in stratospheric halogen loading since the early 1970s, which levelled off after the mid-1990s and then started to decline, in response to the ban of many ODS by the Montreal Protocol (1987). We developed a multiple linear regression model to test whether this already had a measurable effect on total ozone values observed by the global network of ground-based instruments. The model includes explanatory variables describing the influence of various modes of dynamical variability and of volcanic eruptions. In order to describe the anthropogenic influence a first version of the model contains a linear trend (LT) term, whereas a second version contains a term describing the evolution of Equivalent Effective Stratospheric Chlorine (EESC). By comparing the explained variance of these two model versions we evaluated, which of the two terms better describes the observed ozone evolution. For a significant majority of the stations, the EESC proxy fits the long term ozone evolution better than the linear trend term. Therefore, we conclude that the Montreal Protocol has started to show measurable effects on the ozone layer about twenty years after it became legally binding.

    Changes in extreme meteorological variables and the demographic shift towards an older population have made it important to investigate the association of climate variables and hip fracture by advanced methods in order to determine the climate variables that most affect hip fracture incidence. The nonlinear autoregressive moving average with exogenous variable-generalized autoregressive conditional heteroscedasticity (ARMAX-GARCH) and multivariate GARCH (MGARCH) time series approaches were applied to investigate the nonlinear association between hip fracture rate in female and male patients aged 40-74 and 75+ years and climate variables in the period of 1993-2004, in Montreal, Canada. The models describe 50-56% of daily variation in hip fracture rate and identify snow depth, air temperature, day length and air pressure as the influencing variables on the time-varying mean and variance of the hip fracture rate. The conditional covariance between climate variables and hip fracture rate is increasing exponentially, showing that the effect of climate variables on hip fracture rate is most acute when rates are high and climate conditions are at their worst. In Montreal, climate variables, particularly snow depth and air temperature, appear to be important predictors of hip fracture incidence. The association of climate variables and hip fracture does not seem to change linearly with time, but increases exponentially under harsh climate conditions. The results of this study can be used to provide an adaptive climate-related public health program and ti guide allocation of services for avoiding hip fracture risk. PMID:23722925

  4. Economics of "essential use exemptions" for metered-dose inhalers under the Montreal Protocol.

    The Montreal Protocol on Substances that Deplete the Ozone Layer has led to rapid reductions in the use of ozone-depleting substances worldwide. However, the Protocol provides for "essential use exemptions" (EUEs) if there are no "technically and economically feasible" alternatives. An application that might qualify as an "essential use" is CFC-powered medical metered-dose inhalers (MDIs) for the treatment of asthma and chronic obstructive pulmonary disease (COPD), and the US and other nations have applied for exemptions in this case. One concern is that exemptions are necessary to ensure access to medications for low-income uninsureds. We examine the consequences of granting or withholding such exemptions, and conclude that government policies and private-sector programs are available that make it economically feasible to phase out chlorofluorocarbons (CFCs) in this application, thereby furthering the global public health objectives of the Montreal Protocol without compromising the treatment of patients who currently receive medication by means of MDIs.

  6. Protestants, Catholics, and Masonic Conspiracies: The British Association in Montreal (1884).

    2016-03-01

    The British Association for the Advancement of Science (BAAS), like many nineteenth-century institutions, sought to avoid controversy by excluding the discussion of political and religious topics from its proceedings. Nonpartisanship was a veneer it could hide behind. Yet during the Montreal meeting of 1884-the first time the association ventured beyond the comfortable confines of the British Isles-this "middle way" was tested. While local and visiting Anglophones, many of them BAAS members, viewed the proceedings and character of the association as "decidedly friendly" to religion and as promoting the broad interests of Protestants, Montreal's episcopacy and French-speaking press rallied against the anti-Catholic BAAS, accusing it of harboring a dangerous Masonic clique. In different material and social spaces, the relationship between science, religion, and the association was conceived in distinct ways. In examining this case, this essay seeks to augment the growing body of scholarship within science studies that recognizes the importance of writing both the history and the geography of encounters between science and religion.

    This paper describes the urban heat island in Quebec City on a typical clear winter night. This is a follow-up to a study made on a summer night in August 1980; the reader will find a detailed description of the region in Leduc et al. (1980). On February 25, 1980 at 21:30 EST, nearly 200 measurements of temperature were taken at preselected points by 17 mobile observers; a mini-sonde was launched near the Duberger meteorological tower while upper air data were obtained from a sonde launched at Valcartier CFB. Additional data were available from the five regular climatological stations in greater Quebec City and from 2 other thermographs in order to evaluate cooling rates. On the day of the 25th, a developing low pressure area over the eastern coast brought cold air from the northwest toward Quebec City. On that day, the maximum temperature was - 1 °C while the minimum on the following night dropped to - 19 °C. At the time of the experiment, the sky was clear and the winds were westerly at 1.5 m s-1 at the surface and northwesterly at 6 m s-1 at 122 m. A strong inversion was present in the lowest 200 m while upper inversions were noted on the upper air sounding. As noted in the summer experiment, cooling rates, according to the Oke et al. (1972) criteria, reflected a rural behaviour at all stations equipped with a thermograph. It is to be noted that no data on cooling rates are available for the highly urbanized sectors. One notes a relatively warm zone in the downtown area where temperature reached - 8 °C; there is also a cold zone, at the same location as during the summer experiment. The mean temperature gradient between the urban and rural sectors was 5 °C, which is comparable with that observed in August 1979 (6 °C). Thus, the urban heat island does not seem to be more intense in winter than in summer. Relatively large areas of uniform temperature were detected at places where the summer experiment indicated sharp spatial contrasts; this could be

    The snowmelt is an important component of the Soil Water Assessment Tool (SWAT[1]) model's hydrology when applied in snowy watersheds where spring flows are dominated by snow melting. However, little is known about its performance in modeling Nordic environments and its accuracy with respect to operational snowmelt models because most studies were conducted in rainfall-runoff catchments. To fill this gap in SWAT's knowledge, we aim to evaluate its performance for simulating a snowy Nordic catchment streamflow with comparison to the Streamflow Synthesis and Reservoir Regulation (SSARR[2]) model. SSARR is one of the selected operational models by the Snow Hydrology Guide as valuable tool for snowmelt runoff simulation (Ontario Ministry of Natural Resources, 1989). In the Côte Nord region of Quebec, most of the streamflow come from snowmelt in watersheds. Understanding the interactions among snow accumulation, snowmelt and streamflow generation is a challenge for water resources management in Quebec, since this province is the Canada's leader in hydroelectric energy production. The selected snow-covered watershed, namely the Outardes Basin, presents extreme climatic conditions. Few examples of model calibration in this Nordic environment exist because of the scarcity of reliable data. The basin has the interest of being well instrumented providing a comprehensive dataset to implement SWAT over this Nordic watershed. The evaluation indicates that SWAT has a good performance in simulating the daily, monthly, seasonal and annual mean discharges with low volume biases over the calibration and validation periods. The predominantly spring snow-melting generated streamflow is simulated with a good accuracy for both its magnitude and its timing. Seasonal snowpack plays an important role in defining the hydrologic regime where the accumulated snowmelt runoff contributes to 64% of the annual runoff. When we compared SWAT's results to SSARR, comparable performances in

  12. Revisiting physicians' financial incentives in Quebec: a panel system approach.

    PubMed

    Nassiri, Abdelhak; Rochaix, Lise

    2006-01-01

    Do Primary Care Physicians (PCPs) react strategically to financial incentives and if so how? To address this question, we follow a quasi-natural experiment in Quebec, using a panel system technique. In so doing, we both correct for underestimation biases in earlier time series findings and generate new results on the issue of complementarity/substitution between consultations with varying levels of technicality. Under both techniques, we show that PCPs are sensitive to the enforcement and subsequent temporary removals of expenditure caps and more generally, to changes in consultations' relative prices over time. These results support the existence of a discretionary power over the choice of consultation, PCPs increasing strategically the number of the more technical (and therefore more lucrative) consultations when pressed to defend their income. This finding for primary care parallels the now well-established DRG creep in hospitals. The panel system approach offers a better account of the complexity surrounding PCPs' decision-making process. In particular, it successfully addresses issues of physician heterogeneity, jointness between consultations and temporal breaks and generates robust estimates of PCPs volume and quality reactions to regulatory changes.

    This article reports preliminary research results on a professional development (PD) model as a mechanism for supporting absorption of the Healthy School (HS) approach into school functioning. The purpose of our study was to document the model implementation process and understand whether it influenced, or not, the accompanied actors' knowledge and practices about HS. The theoretical basis of the model and a description of its implementation, its appreciation by actors and its influence on their knowledge and confidence are presented. The research was conducted in three Quebec schools that had adopted this approach for at least 2 years. Multiple case study methodology, with pre- (T0) and post- (T1) intervention comparison, was adopted. The results disclose that the PD model implemented, which involves socio-constructivist accompaniment, has several assets that support the acquisition and application of new knowledge related to HS in order to promote its absorption within schools. Our findings indicate that PD likely reinforced the actors' knowledge and understanding as well as their confidence. The lessons drawn from the evaluation of this PD model could serve to enhance accompaniment methods implemented to promote the absorption of such initiatives in schools. Our data highlight the relevance and effectiveness of accompaniment anchored in action, calling for practice based on reflection and expert recommendations to meet the objectives of health and academic success.

    2015-01-01

    Background Inuit communities in northern Quebec have high rates of human papillomavirus (HPV) infection, cervical cancer and cervical cancer–related mortality as compared to the Canadian population. HPV types can be further classified as intratypic variants based on the extent of homology in their nucleotide sequences. There is limited information on the distribution of intratypic variants in circumpolar areas. Objective Our goal was to describe the HPV intratypic variants and associated baseline characteristics. Design We collected cervical cell samples in 2002–2006 from 676 Inuit women between the ages of 15 and 69 years in Nunavik. DNA isolates from high-risk HPVs were sequenced to determine the intratypic variant. Results There were 149 women that were positive for HPVs 16, 18, 31, 33, 35, 45, 52, 56 or 58 during follow-up. There were 5 different HPV16 variants, all of European lineage, among the 57 women positive for this type. There were 8 different variants of HPV18 present and all were of European lineage (n=21). The majority of samples of HPV31 (n=52) were of lineage B. The number of isolates and diversity of the other HPV types was low. Age was the only covariate associated with HPV16 variant category. Conclusions These frequencies are similar to what was seen in another circumpolar region of Canada, although there appears to be less diversity as only European variants were detected. This study shows that most variants were clustered in one lineage for each HPV type. PMID:26653084

    The (87)Sr/(86)Sr isotope ratios were measured on grape, wine and soil samples collected in 13 commercial vineyards located in three major wine producing areas of Quebec (Canada). The soils yield Sr isotope ratios that are intimately related to the local geology and unambiguously discriminate the different producing areas. A strong relationship exists between the (87)Sr/(86)Sr isotope ratios of the wine and the grapes. This suggests that the vinification process does not alter the overall Sr budget. Although the Sr isotope ratios of the grapes do not show a strong correlation with the bulk Sr isotope composition of the soil, they do correlate strongly with the Sr isotope composition contained in the labile fraction of the soil. This indicates that the labile fraction of the soil represents the Sr reservoir available to the plant during its growth. This study demonstrates that the Sr isotope approach can be used as a viable tool in forensic science for investigating the provenance of commercial wines. PMID:27211629

    1988-01-01

    A report on REE concentrations within the estuary of the Great Whale River in northwest Quebec and in Hudson Bay is given, showing concentrations which are less than those predicted by conservative mixing of seawater and river water, indicating removal of REE from solution. REE removal is rapid, occurring primarily at salinities less than 2 percent and ranges from about 70 percent for light REE to no more than 40 percent for heavy REE. At low salinity, Fe removal is essentially complete. The shape of Fe and REE vs. salinity profiles is not consistent with a simple model of destabilization and coagulation of Fe and REE-bearing colloidal material. A linear relationship between the activity of free ion REE(3+) and pH is consistent with a simple ion-exchange model for REE removal. Surface and subsurface samples of Hudson Bay seawater show high REE and La/Yb concentrations relative to average seawater, with the subsurface sample having a Nd concentration of 100 pmol/kg and an epsilon(Nd) of -29.3; characteristics consistent with river inputs of Hudson Bay. This indicates that rivers draining the Canadian Shield are a major source of nonradiogenic Nd and REE to the Atlantic Ocean.

    2016-01-01

    Background Sperm cryopreservation remains the only clinically feasible option to preserve male fertility. The quality of counselling provided by the treating physicians and the cost of sperm cryopreservation can both influence a patient’s decision about whether to preserve sperm. On 5 August 2010, the Quebec government introduced provincial coverage of assisted reproductive technologies, with sperm cryopreservation included as a covered service. The aim of the present study was to evaluate whether and how such a program affects the behaviour of cancer patients with respect to sperm cryopreservation. Methods We analyzed the database derived from male patients undergoing sperm cryopreservation from August 2008 to August 2012 at our centre. The retrieved data included patient age, male infertility or oncologic diagnosis, sperm quality parameters, and details about the number of visits for sperm cryopreservation. Results The number of cancer patients who cryopreserved sperm before and after the policy change did not differ significantly, but a marked increase in the number of non-cancer patients was observed. Further analysis revealed that, after implementation of the public funding program, the total number of sperm cryopreservation sessions per patient increased significantly in cancer patients but not in non-cancer patients. Conclusions It appears that cancer patients who are willing to freeze sperm are keen to return for more sessions of sperm banking when no fees are associated with the service. Those findings suggest that cost reduction is an important factor for improving delivery of fertility preservation services to male cancer patients. PMID:26966400

    The 1,1,1,2-tetrafluoroethane (HFC-134a), an important alternative to CFC-12 in accordance with the Montreal Protocol on Substances that Deplete the Ozone Layer, is a high global warming potential greenhouse gas. Here we evaluate variations in global and regional HFC-134a emissions and emission trends, from 1995 to 2010, at a relatively high spatial and temporal (3.75° in longitude × 2.5° in latitude and 8 day) resolution, using surface HFC-134a measurements. Our results show a progressive increase of global HFC-134a emissions from 19 ± 2 Gg/yr in 1995 to 167 ± 5 Gg/yr in 2010, with both a slowdown in developed countries and a 20%/yr increase in China since 2005. A seasonal cycle is also seen since 2002, which becomes enhanced over time, with larger values during the boreal summer.

    1993-07-01

    Between 23 and 25 November 1992, representatives from more than 100 states gathered in Copenhagen for the Fourth Meeting of the parties to the Montreal Protocol in Substances that Deplete the Ozone Layer. The Copenhagen gathering was significant not only because the international community had to respond to the ongoing deterioration of the Earth`s protective layer of stratospheric ozone, but also because it was one of the first major international environmental conferences to be held after the June 1992 UNCED in Rio de Janeiro. The results of the fourth meeting, discussed in this paper, might therefore suggest the extent to which UNCED cemented the international community`s commitment to the goal of sustainable development.

    Getz, K.A.

    1991-01-01

    This study examines factors influencing the choice of one set of tactics over others. The case of ozone depletion is used as the research context, and the data are drawn from US companies having a stake in this issue. A model is developed which suggests that a firm's choice of political tactics (dependent variable) is dependent on the targets of political activity and the nature of the issue of concern (independent variables), and a variety of organizational and industry factors (moderating variables). The paradigm of agency is used to systematically assess the relative importance of these factors. To test the relevance of the model, an empirical study was done. The case of the Montreal protocol on Substances That Deplete the Ozone Layer was chosen as a setting; and 551 firms directly affected by policy intended to protect the ozone layer were surveyed. There were 151 usable responses. Generally, the findings were consistent with the model.

    The Montreal Cognitive Assessment (MoCA) is a brief screening instrument for dementia that is sensitive to executive dysfunction. This study examined its usefulness for assessing cognitive performance in mild, moderate, and severe Huntington’s disease (HD), as compared to the MMSE. We compared MoCA and MMSE total scores and the number of correct answers in five cognitive-specific domains in 104 manifest HD patients and 100 matched controls. For the total HD sample, and for the moderate and severe patients, significant differences between both MoCA and MMSE total scores and almost all cognitive-specific domains emerged. Even mild HD subjects showed significant differences with regard to total score and several cognitive domains on both instruments. We conclude that the MoCA, although not necessarily superior to the MMSE, is a useful instrument for assessing cognitive performance over a broad level of functioning in HD. PMID:23798501

    The Montreal Cognitive Assessment (MoCA) is a brief cognitive instrument for the measurement of dementia. The aim of the present study is to provide normative data for the MoCA test in the Greek speaking population and to measure its validity in a clinical group of parkinsonian dementia participants. A total of 710 healthy Greek speaking participants and 19 parkinsonian dementia participants took part in the study. Both, the MoCA test and a neuropsychological test battery (digit span, semantic verbal fluency, phonemic verbal fluency, Color Trails Test) were administered to the normative and clinical samples. The test was found to correlate with all neuropsychological tests used in the test battery and it showed high discriminant validity (optimal screening cutoff point = 21, sensitivity = 0.82, specificity = 0.90) in the parkinsonian dementia participants. Further research is needed to use it in larger clinical samples and in different neurological diseases. PMID:26891720

    In the City of Montreal, 1881, the presence of three cultural communities with different profiles of economic status makes it possible to observe the way social settings affected survival over a lifetime. Regression models show culturally determined maternal factors dominant for infants, and persistent throughout childhood. For post-neonates, children aged 1-4, and adults aged 15-59 household poverty has a comparable effect. Among adults, a gender penalty differs among the three communities. Models are improved when differentiated by cause of death. Locating households using a GIS reveals high levels of residential segregation by ethnicity and income, spatial correlation of environmental hazards, and constraints on exit from zones of risk, which together produce neighbourhood effects as large as household effects. Attention to groups excluded (foundlings and inmates of institutions) confirms that models limited to full household-level information significantly underestimate the impacts of poverty and exclusion.

    The aim of this study was to assess certain musical abilities in 30 patients with Alzheimer's disease (AD) and 30 healthy controls by using the complete version of the Montreal Battery of Evaluation of Amusia (MBEA). This battery evaluates melodic (scale, contour, and interval) and temporal (rhythm and meter) perception of music and musical memory. We found that altered musical processing is a common feature in AD. Despite that, AD subjects show partially spared abilities for temporal organization of music, though not for melodic perception and musical memory. This peculiar dysfunctional pattern could depend on the neurodegenerative involvement of some specific areas for music perception and memory in the brains of AD patients. Further studies are needed to investigate the usefulness of additional musical tests like the MBEA on larger samples to confirm our preliminary data. PMID:27447536

    Organizational Strategies for Critical Transportation Infrastructure: Characteristics of Urban Resilience. The Case of Montreal. Stéphane Beauregard M.Sc. Candidate École nationale d'administration publique Julie-Maude Normandin Ph.D. Candidate École nationale d'administration publique Marie-Christine Therrien Professor École nationale d'administration publique The proposed paper presents preliminary results on the resilience of organizations managing critical infrastructure in the Metropolitan Montreal area (Canada). A resilient city is characterized by a network of infrastructures and individuals capable of maintaining their activities in spite of a disturbance (Godschalk, 2002). Critical infrastructures provide essential services for the functioning of society. In a crisis situation, the interruption or a decrease in performance of critical infrastructures could have important impacts on the population. They are also vulnerable to accidents and cascading effects because on their complexity and tight interdependence (Perrow, 1984). For these reasons, protection and security of the essential assets and networks are one of the objectives of organizations and governments. But prevention and recovery are two endpoints of a continuum which include also intermediate concerns: ensuring organizational robustness or failing with elegance rather than catastrophically. This continuum also includes organizational resilience (or system), or the ability to recover quickly after an interruption has occurred. Wildavsky (1988) proposes that anticipation strategies work better against known problems while resilience strategies focus on unknown problems. Anticipation policies can unnecessarily immobilize investments against risks, while resilience strategies include the potential for a certain sacrifice in the interests of a more long-term survival and adaptation to changing threats. In addition, a too large confidence in anticipation strategies can bring loss of capacity of an

    La determination de l'impact des facteurs sous controle et hors controle qui influencent les volumes de vente des magasins de detail qui vendent des produits homogenes et fortement substituables constitue le coeur de cette these. Il s'agit d'estimer un ensemble de coefficients stables et asymtotiquement efficaces non correles avec les effets specifiques aleatoires des sites d'essence dans le marche de Montreal (Quebec, Canada) durant is periode 1993--1997. Le modele econometrique qui est ainsi specifie et teste, isole un ensemble de quatre variables dont le prix de detail affiche dans un site d'essence ordinaire, la capacite de service du site pendant les heures de pointe, les heures de service et le nombre de sites concurrents au voisinage du site dans un rayon de deux kilometres. Ces quatre facteurs influencent les ventes d'essence dans les stations-service. Les donnees en panel avec les methodes d'estimation robustes (estimateur a distance minimale) sont utilisees pour estimer les parametres du modele de vente. Nous partons avec l'hypothese generale selon laquelle il se developpe une force d'attraction qui attire les clients automobilistes dans chaque site, et qui lui permet de realiser les ventes. Cette capacite d'attraction varie d'un site a un autre et cela est du a la combinaison de l'effort marketing et de l'environnement concurrentiel autour du site. Les notions de voisinage et de concurrence spatiale expliquent les comportements des decideurs qui gerent les sites. Le but de cette these est de developper un outil d'aide a la decision (modele analytique) pour permettre aux gestionnaires des chaines de stations-service d'affecter efficacement les ressources commerciales dans ies points de vente.

    Background: Magnetic resonance imaging (MRI) has improved the diagnosis and management of patients with multiple sclerosis (MS). Montreal Cognitive Assessment (MoCA) is a brief, sensitive test that has been recommended by National Institute of Neurological Diseases and Stroke and Canadian Stroke Network (NINDS-CSN) as a reliable tool to detect mild cognitive impairments. This study aimed to evaluate the relationship between MoCA test and its sub-items with brain abnormalities in MRI of MS patients. Methods: Based on MRI scans of 46 MS patients, third ventricle and white matter lesions volumes were measured. Disease duration and expanded disability status scale (EDSS) were recorded in each patient. In addition, cognitive domains of the patients were evaluated by Montreal cognitive assessment (MoCA) test. We analyzed data using t-test or Mann-Whitney U test, Pearson correlation coefficient, and non-parametric Spearman test. Furthermore, multiple linear regression model was applied to evaluate the association between cognitive indices and MRI characteristics. Results: Among MRI indices, only severity of atrophy showed a significant difference between cognitively impaired and cognitively preserved patients. Third ventricular volume was significantly correlated with total MoCA score (p=0.003, r=-0.42), but none of the juxtacortical or periventricular lesions volume revealed significant relation with total MoCA score. However, using multivariate linear regression after adjustment for educational level and disease duration, there was a significant negative association between juxtacortical lesions volume and total MoCA score as well as naming and attention sub-items. Also, memory score was adversely associated with the third ventricular volume (p=0.03, r=0.31). Conclusion: Cognitive disturbances detected by MoCA, may be associated with some pathological changes including atrophy, third ventricular volume, and juxtacortical lesion. MoCA, as a brief test, is not correlated

    A significant percentage of the northern Quebec boreal region consists of minerotrophic peatland. Their impact on large-scale watersheds, used for hydroelectric production, is important, especially in relation to climate change. During the last decades, a subtle increase in the surface of ponds at the expense of terrestrial compartments has been observed. To better understand the impacts of this development, a multidisciplinary study to perform a complete integrated analysis of the water balance was launched in summer 2008 on the Abeille peatland (54° 06'52" N, 72° 30'01"W), a minerotrophic peatland with an open-water surface. While all features of the water balance will be considered (precipitation, evapotranspiration, runoff, storage and error), some will be studied in greater depth. Notably, evapotranspiration and storage changes will be considered, since, they are particularly difficult to measure in peatland ecosystems. Indirect methods for estimating actual evapotranspiration are often used. One method is to use a semi-empirical formula to estimate potential evapotranspiration. The main problem with this method is that a relationship between potential and actual evapotranspiration must be established and this is a highly variable process for peat ecosystems. To establish a relationship appropriate to our study site, different methods of direct measurement of the actual evapotranspiration will be used (lysimeters, turbulence flow, daily fluctuations of storage, etc.) and compared. A dense network of wells has been installed to enable monitoring of changes in storage and subsurface runoff. A high accuracy topographic survey will be executed to assess the total water content of the site. A device for measuring the variation of peat surface elevation will also be established. Preliminary results are showing complex dynamic behaviors of water migration through the site, therefore opening the way to new questions and hypotheses to clarify in the coming years.

  18. Public participation in strategic environmental assessment (SEA): Critical review and the Quebec (Canada) approach

    2011-01-15

    It is widely accepted that public participation must be a part of strategic environmental assessment (SEA) procedures, and yet few studies have been conducted on the implementation of SEA public participation procedures. Accordingly, the theoretical and practical aspects of public participation in SEA remain research priorities for environmental policy-making. This paper presents a review of the Quebec (Canada) model of public participation in SEA through an evaluation of six public hearings on proposed directions and policies concerning, respectively, hazardous waste, forest protection, residual materials, energy, water management and pig farming. First, the authors examine the theoretical dimensions of SEA and public participation in the process. Second, they give a summary of the lessons that can be learned from the few Canadian and international experiences. Third, they outline the Quebec experience. Finally, they conclude by evaluating the opportunities and limitations of the Quebec experience and make some recommendations to improve its application.

    Black carbon (BC), an important component of the global soil carbon pool, is a major by-product of wildfires in Quebec black spruce forests. However, BC characteristics vary depending on the environmental conditions under which it is formed and this may further affect its resistance to degradation. The objective of this study was to characterize the chemical and physical properties of BC formed under variable fire severity to assess its potential for recalcitrance as a passive carbon pool. Samples (n = 267) of BC produced by early season wildfires in 2005-2007 were collected from the surface of black spruce forest floors to cover the range of severity encountered in these fire-affected forests. Representative samples (n = 33) were then analyzed using elemental analysis, solid-state 13C nuclear magnetic resonance (NMR) spectroscopy, scanning electron microscopy and surface area analysis (BET method). Properties of BC sampled in the field were compared with those of samples produced under a range of controlled formation conditions in the laboratory. The NMR spectra of the BC collected on sites affected by low fire severity showed a distribution of total intensity between the different spectral regions very similar to those of unburned fuels, and were dominated by peaks indicative of cellulose, while spectra for BC from higher fire severity sites were dominated by a broad peak assigned to aromatic carbons. Atomic H/C and O/C ratios decreased along the fire severity gradient, confirming that increasing severity was associated with an increase in condensation. By comparing field- to laboratory-produced samples, we concluded that the temperature of formation in the field ranged between 75 and 250 ° C. In all analyzed BC samples, the fraction of aromatic carbon:total carbon was low, suggesting that the freshly produced BC in this boreal forest environment may be susceptible to rapid physical alteration and chemical degradation. Nevertheless, it is important to highlight

    1999-01-01

    Family structure has been evolving in Quebec for approximately 30 years. This second demographic transition is especially characterized by the marked growth in the number and proportion of unmarried couples. Data from the 1995 General Social Study (ESG) were used in a study of the beginning of married life for Quebec women. The first union is particularly important in a person¿s life cycle because it often takes place at the same time as one¿s formal studies are concluding, entrance into professional/employed life, and departure from the parental home. The authors explored the relative importance of free unions in Quebec. A multivariate analysis provided a measure of the influence of demographic and socioeconomic characteristics upon the risk that Quebec women run of either entering an open union or formal marriage when they begin their lives with a partner. Schooling level and activity are used to empirically evaluate the theory of independence, while the authors also measure the effect of characteristics such as generation, the presence of a child, place of birth, maternal language, and religious practice. The analysis considers the stability of the family of origin. PMID:12349519

    The Bedrock Geologic Map of Maine was digitized and combined with digital geologic data for Quebec and the Gulf of Maine for the Quebec-Maine-Gulf of Maine Geologic Transect Project. This map is being combined with digital geophysical data to produce three-dimensional depictions of the subsurface geology and to produce cross sections of the Earth's crust. It is an essential component of a transect that stretches from the craton near Quebec City, Quebec, to the Atlantic Ocean Basin south of Georges Bank. The transect is part of the Global Geosciences Transect Project of the International Lithosphere Program. The Digital Line Graph format is used for storage of the digitized data. A coding scheme similar to that used for base category planimetric data was developed to assign numeric codes to the digitized geologic data. These codes were used to assign attributes to polygon and line features to describe rock type, age, name, tectonic setting of original deposition, mineralogy, and composition of igneous plutonic rocks, as well as faults and other linear features. The digital geologic data can be readily edited, rescaled, and reprojected. The attribute codes allow generalization and selective retrieval of the geologic features. The codes allow assignment of map colors based on age, lithology, or other attribute. The Digital Line Graph format is a general transfer format that is supported by many software vendors and is easily transferred between systems.

  8. Shunning the Bird's Eye View: General Science in the Schools of Ontario and Quebec

    NASA Astrophysics Data System (ADS)

    Hoffman, Michelle

    2013-04-01

    This paper considers the adoption of general science courses in two Canadian provinces, Ontario and Quebec, during the 1930s. In Ontario, a few science teachers had followed the early general science movements in the United States and Britain with interest. During the 1930s, several developments made the cross-disciplinary, applied thrust of general science particularly appealing to Ontario educationists. These developments included a new demand for vocational education, renewed reservations about pedagogical rationales based on transfer of training, and a growing professional divide between high school science teachers and university scientists. Around the same time, scientists in the Quebec's French-language universities were engaged in a concerted campaign to expand the place of science in the province's francophone secondary schools. The province's prestigious classical colleges, which were the scientists' principal target for reform, privileged an inductive view of science that had little in common with the applied, cross-disciplinary emphasis of the general science courses gaining support in English-speaking school systems. In 1934, however, a popular American general science textbook was adopted in a workers' cooperative devoted to adult education. Comparing the fate of general science within these two education systems draws attention to the fact that general science made inroads in francophone Quebec but had little influence in public and private schools. In light of the growing support general science enjoyed elsewhere, we are led to explore why general science met with little overt interest by Quebec scientists pushing for school science reform during the 1930s.

    After its modest beginnings focusing on arctic Quebec in 1999, the Quebec research programme on health and climate change became interested in the remainder of the province around 2002. The European heat wave in 2003 accelerated the pace of this programme and prompted the Quebec health sector's participation in the Ouranos Research Consortium. The research findings from the 2003-2006 period have directly fed into the health component of the Quebec government's climate change action plan (2006-2012), financed through the first carbon tax in the Americas. This component is planning for a series of adaptations to the health network and to some other public networks, which will apply to construction, the built environment and outdoor developments, clinical management methods and practices, public health surveillance as well as emergency preparedness. In this article, the authors describe how research is supporting action and implementation, while also preparing for the future, and how this interaction has progressively established itself over the last 10 years.

    2015-01-01

    The author is the witness of a historic period of the psychiatry in the province of Quebec in Canada, widely francophone. He describes the context, the training in psychiatry, and the care. In Quebec, in the 1950s, the psychiatry did not exist as such as speciality. There was however a discipline: the neuropsychiatry. It was managed by the neurologists who agreed to take care of cases of psychiatry, which few doctors wanted to treat at this moment. The religious and rural society in Quebec of the 1950s got ready for the "Revolution tranquille". The latter finally burst after 1960. But the artistic environment was already in full excitement, and from 1948, it showed its opposition to the values which were current with the publication of the Refus global. Among the signatories of the latter, we find Bruno Cormier as medical student who will become, after 1950, a psychiatrist and a psychoanalyst. To become a psychiatrist, it was necessary to be trained as an intern in a residency program in the USA, UK or in France. The residency in the United States in the 1950s represented a great adventure for the young doctors of Quebec, especially for the French speakers. At the end of 1950s, the pharmacology emerged. However, he described his own experience as an observer or an actor with ECT, Sakel cure and about the lobotomy. PMID:26559204

    The ozone layer is the Earth's natural sunscreen, blocking harmful solar ultraviolet radiation. In 1974, Mario Molina and F. Sherwood Rowland proposed that the ozone layer could be depleted by chlorine released from human-produced chlorofluorocarbons (CFCs). Follow-up science investigations supported this hypothesis, leading to the landmark 1987 Montreal Protocol on Substances That Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer). One of the Montreal Protocol provisions is that science assessments on ozone depletion be written and submitted to the signatory Parties every 4 years. In this talk, I will primarily focus on the science findings from the recently published "Scientific Assessment of Ozone Depletion: 2010". This assessment is written and reviewed (multiple times) by the international science community. The 2010 assessment is the latest in a long series of reports that provide the science foundation for the Montreal Protocol. This assessment demonstrates that the Montreal Protocol is working, and that there are early signs that ozone is beginning to respond to decreasing CFC levels. There are now state-of-the-art simulations that show that the ozone layer would have been largely destroyed if CFCs had not been regulated, and therefore extreme levels of UV radiation have been avoided. The 2010 assessment also spotlights new insights into the impact of ozone depletion on surface climate, and climate impacts on ozone. However, the assessment also reveals that greenhouse gases are modifying the stratosphere and that the ozone layer will evolve into a different state than its pre-industrial values - you can't go home again.

  12. Comparison of Alternate and Original Items on the Montreal Cognitive Assessment

    Background The Montreal Cognitive Assessment (MoCA) is a screening tool for mild cognitive impairment (MCI) in elderly individuals. We hypothesized that measurement error when using the new alternate MoCA versions to monitor change over time could be related to the use of items that are not of comparable difficulty to their corresponding originals of similar content. The objective of this study was to compare the difficulty of the alternate MoCA items to the original ones. Methods Five selected items from alternate versions of the MoCA were included with items from the original MoCA administered adaptively to geriatric outpatients (N = 78). Rasch analysis was used to estimate the difficulty level of the items. Results None of the five items from the alternate versions matched the difficulty level of their corresponding original items. Conclusions This study demonstrates the potential benefits of a Rasch analysis-based approach for selecting items during the process of development of parallel forms. The results suggest that better match of the items from different MoCA forms by their difficulty would result in higher sensitivity to changes in cognitive function over time. PMID:27076861

    An analysis of the household refrigeration sector and the foams sector investigates how Chinese enterprises have adopted cleaner technologies involving substitutes for ozone depleting substances (ODSs), such as chlorofluorocarbons (CFCs). The performance of the household refrigeration sector in reducing ODS consumption has been superior to that of the foams sector, even though required technology changes are relatively simple for the foams sector. There are two expansions for this outcome. First, market demand matters. The influence of the global market, multinational corporations, intense (and occasionally misleading) advertising about non-CFC products, and severe competition for consumers caused China`s principal refrigerator manufacturers to adopt non-CFC production technologies. Similar incentives did not exist for enterprises in the foams sector. Second, industrial structure matters. The foams sector includes a large number of small enterprises with limited financial and technical capability and weak access to information and technology, and these factors obstructed technological change. In general, assistance from the Multilateral fund established under the Montreal Protocol has motivated enterprises to shift to ODS reduction technologies, but complex and lengthy procedures for accessing the Multilateral Fund, difficulties in finding appropriate suppliers of non-CFC technologies, and insufficient financial an technical capabilities of many enterprises have slowed down this shift. The results provide a foundation for making changes in international assistance programs and China`s strategies for CFC reduction.

    2015-06-01

    We have developed a chemical mechanism describing the tropospheric degradation of chlorine containing very short-lived substances (VSLS). The scheme was included in a global atmospheric model and used to quantify the stratospheric injection of chlorine from anthropogenic VSLS ( ClyVSLS) between 2005 and 2013. By constraining the model with surface measurements of chloroform (CHCl3), dichloromethane (CH2Cl2), tetrachloroethene (C2Cl4), trichloroethene (C2HCl3), and 1,2-dichloroethane (CH2ClCH2Cl), we infer a 2013 ClyVSLS mixing ratio of 123 parts per trillion (ppt). Stratospheric injection of source gases dominates this supply, accounting for ˜83% of the total. The remainder comes from VSLS-derived organic products, phosgene (COCl2, 7%) and formyl chloride (CHClO, 2%), and also hydrogen chloride (HCl, 8%). Stratospheric ClyVSLS increased by ˜52% between 2005 and 2013, with a mean growth rate of 3.7 ppt Cl/yr. This increase is due to recent and ongoing growth in anthropogenic CH2Cl2—the most abundant chlorinated VSLS not controlled by the Montreal Protocol.

    Language barriers are often cited as a factor contributing to ethnic inequalities in occupational health; however, little information is available about the mechanisms at play. The authors describe the multiple ways in which language influences occupational health in a large garment factory employing many immigrants in Montreal. Between 2004 and 2006, individual, semi-structured interviews were conducted with 15 women and 10 men from 14 countries of birth. Interviews were conducted in French and English, Canada's official languages, as well as in non-official languages with the help of colleague-interpreters. Observation within the workplace was also carried out at various times during the project. The authors describe how proficiency in the official languages influences occupational health by affecting workers' ability to understand and communicate information, and supporting relationships that can affect work-related health. They also describe workers' strategies to address communication barriers and discuss the implications of these strategies from an occupational health standpoint. Along with the longer-term objectives of integrating immigrants into the linguistic majority and addressing structural conditions that can affect health, policies and practices need to be put in place to protect the health and well-being of those who face language barriers in the short term.

    The psychometric properties of the Montreal Cognitive Assessment (MoCA) were examined by using the Partial Credit Model. The study sample included 897 participants who were distributed into two main subgroups: (I) the clinical group (90 patients with Mild Cognitive Impairment, 90 patients with Alzheimer's disease, 33 patients with Frontotemporal Dementia, and 34 patients with Vascular dementia, whose diagnoses were previously established according to a consensus that was reached by a multidisciplinary team, based on the international criteria) and (II) the healthy group (composed of 650 cognitively healthy community dwellers). The results show (i) an overall good fit for both the items and the persons' values, (ii) high variability for the cognitive performance level of the cognitive domains (ranging between 1.90 and -3.35, where "Short-term Memory" was the most difficult item and "Spatial Orientation" was the easiest item) and between the subjects on the scale, (iii) high reliability for the estimation of the persons' values, (iv) good discriminant validity and high diagnostic utility, and (v) a minimal differential item functioning effect related to of pathology, gender, age, and educational level. MoCA and its cognitive domains are suitable measures to use for screening the cognitive status of cognitively healthy subjects and patients with cognitive impairment. PMID:25944337

    Delegates from around the world are meeting in Copenhagen this week to debate an accelerated phaseout of chlorofluorocarbons (CFCs), a time schedule for the eventual phaseout of hydrochlorofluorocarbons (HCFCs), and phaseouts of methyl chloroform and carbon tetrachloride. The fate of methyl bromide will also be a hot issue. The fourth meeting of the parties to the Montreal Protocol is widely expected to put through a 100% CFC phaseout by Jan. 1, 1996, coming into agreement with current US and European Community rules. But debate continues over the intermediate phaseout schedule, with European members pushing for an 85% reduction - from a 1986 baseline - by Jan. 1, 1994, and others arguing for a 70% cut by 1994. Delegates are expected to agree to the final phaseout of halons on Jan. 1, 1996, with an 85% cut in carbon tet by 1995. The meeting is also expected to broadly agree on a Jan. 1, 1996 phaseout of methyl chloroform, with a 50% reduction from a 1989 baseline by Jan. 1, 1994. A critical debate for chemical producers will be on the fate of methyl bromide. Many observers expect some phaseout for the chemical, but when and how is undetermined.

    The study contributes to literature on bicycle safety by building on the traditional count regression models to investigate factors affecting bicycle crashes at the Traffic Analysis Zone (TAZ) level. TAZ is a traffic related geographic entity which is most frequently used as spatial unit for macroscopic crash risk analysis. In conventional count models, the impact of exogenous factors is restricted to be the same across the entire region. However, it is possible that the influence of exogenous factors might vary across different TAZs. To accommodate for the potential variation in the impact of exogenous factors we formulate latent segmentation based count models. Specifically, we formulate and estimate latent segmentation based Poisson (LP) and latent segmentation based Negative Binomial (LNB) models to study bicycle crash counts. In our latent segmentation approach, we allow for more than two segments and also consider a large set of variables in segmentation and segment specific models. The formulated models are estimated using bicycle-motor vehicle crash data from the Island of Montreal and City of Toronto for the years 2006 through 2010. The TAZ level variables considered in our analysis include accessibility measures, exposure measures, sociodemographic characteristics, socioeconomic characteristics, road network characteristics and built environment. A policy analysis is also conducted to illustrate the applicability of the proposed model for planning purposes. This macro-level research would assist decision makers, transportation officials and community planners to make informed decisions to proactively improve bicycle safety - a prerequisite to promoting a culture of active transportation.

    The Montreal Cognitive Assessment (MoCA) is a brief cognitive screening instrument developed by Nasreddine et al. to detect mild cognitive impairment, a high-risk condition for Alzheimer's disease and other forms of dementia. In this study we report normative data on the MoCA-Italian version, collected on a sample of 225 Italian healthy subjects ranged in age between 60 and 80 years, and in formal education from 5 to 23 years. The global normal cognition was established in accordance with the Mini-Mental State Examination score and with the Prose Memory Test score (Spinnler and Tognoni, Ital J Neurol Sci 6:25-27, 1987). None of the participants had a history of psychiatric, neurological, cerebrovascular disorders or brain injury or took drugs affecting cognition. Linear regression analysis was performed to evaluate the potential effect of age, education and sex on the MoCA total performance score. We provide correction grids to adjust raw scores and equivalent scores with cut-off value to allow comparison between MoCA performance and others neuropsychological test scores that can be administered on the same subject.

    A 1995 pilot study assessed sport fish consumption and contaminant exposure among Montreal-area residents fishing the frozen St. Lawrence river. Interviews conducted among 223 ice fishers met on-site were used to create an index of estimated exposure to fish-borne contaminants. A second-stage assessment of sport fish consumption and tissue contaminant burdens included 25 interviewees at the highest level of estimated contaminant exposure and 15 low-exposure fishers. High-level fisher-consumers reported eating 0.92 {+-} 0.99 sport fish meals/week during the previous 3 weeks compared to 0.38 {+-} 0.21 for the low-level group. Based on the product of consumption frequency times mass of sport fish meals consumed, high-level consumers ate a mean of 18.3 kg of sport fish annually versus 3.3 kg for the low-level consumers. Tissue contaminant assessments showed significant groupwise differences: 0--1 cm hair mercury, lipid-adjusted plasma PCB congeners, and lipid-adjusted plasma DDE. No participant had a hair mercury or plasma DDE concentration above Health Canada recommendations but 2/25 high-level participants had plasma Aroclor 1260 concentrations above recommended limits.

    In 2007, a Filipina organization in Quebec (PINAY) sought the help of university researchers to document the workplace health and safety experiences of domestic workers. Together, they surveyed 150 domestic workers and produced a report that generated interest from community groups, policy-makers, and the media. In this article, we-the university researchers-offer a case study of community-university action research. We share the story of how one project contributed to academic knowledge of domestic workers' health and safety experiences and also to a related policy campaign. We describe how Quebec workers' compensation legislation excludes domestic workers, and we analyze the occupational health literature related to domestic work. Striking data related to workplace accidents and illnesses emerged from the survey, and interesting lessons were learned about how occupational health questions should be posed. We conclude with a description of the successful policy advocacy that was possible as an outcome of this project. PMID:21342868

    According to the Montreal Consensus Group's classification, gastroesophageal reflux disease develops when the reflux of stomach contents causes troublesome symptoms and/or complications such as esophagitis. The characteristic gastroesophageal reflux disease symptoms included in this statement are retrosternal burning and regurgitation. Troublesome is meant to imply that these symptoms impact on the well-being of affected individuals; in essence, quality of life (QOL). Whether heartburn and regurgitation symptoms would be characterized as more troublesome in those with confirmed pathologic acid reflux was determined. A second purpose was to assess how well troublesome scores correlated with the results of a validated, disease-specific QOL instrument. Subjects who underwent esophagogastroduodenoscopy (EGD) with 48-hour wireless esophageal pH testing off proton pump inhibitor therapy were interviewed. Esophagitis on EGD or pH < 4.0 for ≥4.5% of time over the 2-day period was considered positive for acid reflux. Assessment of how troublesome their symptoms of heartburn and regurgitation were made using separate 0-100 visual analog scales (VAS). Subjects were then asked to complete the Quality of Life in Reflux and Dyspepsia (QOLRAD) 25-item questionnaire. Sixty-seven patients (21 males, 46 females) with mean age 47.8 ± 15.6 years were identified. Forty (59.7%) had an EGD or pH study positive for acid reflux. Overall 35/40 (87.5%) complained of either heartburn or regurgitation. There was no difference (P= 0.80) in heartburn VAS troublesome ratings for those with (54.0 ± 43.9) and without (56.7 ± 37.6) confirmed acid reflux. The same was true for regurgitation VAS troublesome ratings (P= 0.62). Likewise, mean QOLRAD scores did not differ between those with and without confirmed acid reflux by pH or EGD (4.5 ± 1.7 vs. 4.3 ± 1.7; P= 0.61). There was a moderately strong inverse correlation between patient self-rated VAS troublesome scores for both heartburn and

It reviews and discusses the current usage of the MBEA in relation to cut-off scores, number of used subtests, manner of testing, and employed statistics, as these vary in the literature. Furthermore, data are presented from a large-scale experiment with 228 German undergraduate students who were assessed with the MBEA and a comprehensive questionnaire. This experiment tested the difference between scores that were obtained in a web-based study (at participants' homes) and those obtained under laboratory conditions with a computerized version of the MBEA. In addition to traditional statistical procedures, the data were evaluated using Signal Detection Theory (SDT; Green and Swets, 1966), taking into consideration the individual's ability to discriminate and their response bias. Results show that using SDT for scoring instead of proportion correct offers a bias-free and normally distributed measure of discrimination ability. It is also demonstrated that a diagnosis based on an average score leads to cases of misdiagnosis. The prevalence of congenital amusia is shown to depend highly on the statistical criterion that is applied as cut-off score and on the number of subtests that is considered for the diagnosis. In addition, three different subtypes of amusics were found in our sample. Lastly, significant differences between the web-based and the laboratory group were found, giving rise to questions about the validity of web-based experimentation. PMID:25883562

    Short-lived, anthropogenically produced chlorinated gases historically have not been controlled by the Montreal Protocol; their contribution to stratospheric halogen loading has been relatively small and constant. Since 2000, however, tropospheric mole fractions of dichloromethane (mean lifetime of 5 months) have increased by a factor of 2 at remote sites throughout the globe. Dichloromethane currently adds more chlorine to the atmosphere (~80 ppt) than either HCFC-141b or HCFC-142b, and the implied resulting increase in stratospheric chlorine in recent years is comparable to the increase in total Cl from HCFCs. Emissions driving this global increase have been estimated at 800 Gg/yr in 2012, which is more than half of the chlorine emitted from the three main CFCs during their peak emissions in the late 1980s. Although dichloromethane is used typically as a cleaning agent, solvent, and feedstock in the production of other chemicals, the cause of the recent atmospheric increase is not well understood. Here we will show that the substantial increase in emissions does not appear to be coming from the U.S., as our ongoing observations from tall towers and aircraft profiles over North America since 2005 show a decreasing trend in measured mole fractions in the continental boundary layer relative to the background atmosphere during this period. Instead, our data from remote sites across the Northern Hemisphere reveal a shift in the atmospheric distribution of dichloromethane since 2000 that implies increased emissions from lower latitudes in the northern hemisphere. These changing distributions will be presented and discussed, along with an exploration of the potential causes for the large inter-annual variations observed in the rate of increase and what the results suggest about the main loss mechanism for dichloromethane: oxidation by the hydroxyl radical.

    The objective of our study was to measure the impact of transportation-related noise and total environmental noise on sleep disturbance for the residents of Montreal, Canada. A telephone-based survey on noise-related sleep disturbance among 4336 persons aged 18 years and over was conducted. LNight for each study participant was estimated using a land use regression (LUR) model. Distance of the respondent’s residence to the nearest transportation noise source was also used as an indicator of noise exposure. The proportion of the population whose sleep was disturbed by outdoor environmental noise in the past 4 weeks was 12.4%. The proportion of those affected by road traffic, airplane and railway noise was 4.2%, 1.5% and 1.1%, respectively. We observed an increased prevalence in sleep disturbance for those exposed to both rail and road noise when compared for those exposed to road only. We did not observe an increased prevalence in sleep disturbance for those that were both exposed to road and planes when compared to those exposed to road or planes only. We developed regression models to assess the marginal proportion of sleep disturbance as a function of estimated LNight and distance to transportation noise sources. In our models, sleep disturbance increased with proximity to transportation noise sources (railway, airplane and road traffic) and with increasing LNight values. Our study provides a quantitative estimate of the association between total environmental noise levels estimated using an LUR model and sleep disturbance from transportation noise. PMID:27529260

    Background. Sparse data limit the interpretation of Montreal Cognitive Assessment (MoCA) scores, particularly in minority populations. Additionally, there are no published data on how MoCA scores compare to the widely used Modified Mini Mental State Examination (3MSE). We provide performance data on the MoCA in a large cohort of African Americans and compare 3MSE and MoCA scores, providing a “crosswalk” for interpreting scores. Methods. Five hundred and thirty African Americans with type 2 diabetes were enrolled in African American-Diabetes Heart Study-MIND, a cross-sectional study of cognition and structural and functional brain imaging. After excluding participants with possible cognitive impairment (n = 115), mean (SD) MoCA and 3MSE scores are presented stratified by age and education. Results. Participant mean age was 58.2 years (range: 35-83); 61% were female; and 64.9% had >12 years of education. Mean (SD) 3MSE and MoCA scores were 86.9 (8.2) and 19.8 (3.8), respectively. 93.5% of the cohort had a “positive” screen on the MoCA, scoring <26 (education-adjusted), compared with 47.5% on the 3MSE (cut-point < 88). A 3MSE score of 88 corresponded to a MoCA score of 20 in this population. Conclusion. The present data suggest the need for caution when applying proposed MoCA cutoffs to African Americans.

    Manual processing of sleep recordings is extremely time-consuming. Efforts to automate this process have shown promising results, but automatic systems are generally evaluated on private databases, not allowing accurate cross-validation with other systems. In lacking a common benchmark, the relative performances of different systems are not compared easily and advances are compromised. To address this fundamental methodological impediment to sleep study, we propose an open-access database of polysomnographic biosignals. To build this database, whole-night recordings from 200 participants [97 males (aged 42.9 ± 19.8 years) and 103 females (aged 38.3 ± 18.9 years); age range: 18-76 years] were pooled from eight different research protocols performed in three different hospital-based sleep laboratories. All recordings feature a sampling frequency of 256 Hz and an electroencephalography (EEG) montage of 4-20 channels plus standard electro-oculography (EOG), electromyography (EMG), electrocardiography (ECG) and respiratory signals. Access to the database can be obtained through the Montreal Archive of Sleep Studies (MASS) website (http://www.ceams-carsm.ca/en/MASS), and requires only affiliation with a research institution and prior approval by the applicant's local ethical review board. Providing the research community with access to this free and open sleep database is expected to facilitate the development and cross-validation of sleep analysis automation systems. It is also expected that such a shared resource will be a catalyst for cross-centre collaborations on difficult topics such as improving inter-rater agreement on sleep stage scoring. PMID:24909981

    The objective of our study was to measure the impact of transportation-related noise and total environmental noise on sleep disturbance for the residents of Montreal, Canada. A telephone-based survey on noise-related sleep disturbance among 4336 persons aged 18 years and over was conducted. LNight for each study participant was estimated using a land use regression (LUR) model. Distance of the respondent's residence to the nearest transportation noise source was also used as an indicator of noise exposure. The proportion of the population whose sleep was disturbed by outdoor environmental noise in the past 4 weeks was 12.4%. The proportion of those affected by road traffic, airplane and railway noise was 4.2%, 1.5% and 1.1%, respectively. We observed an increased prevalence in sleep disturbance for those exposed to both rail and road noise when compared for those exposed to road only. We did not observe an increased prevalence in sleep disturbance for those that were both exposed to road and planes when compared to those exposed to road or planes only. We developed regression models to assess the marginal proportion of sleep disturbance as a function of estimated LNight and distance to transportation noise sources. In our models, sleep disturbance increased with proximity to transportation noise sources (railway, airplane and road traffic) and with increasing LNight values. Our study provides a quantitative estimate of the association between total environmental noise levels estimated using an LUR model and sleep disturbance from transportation noise. PMID:27529260

Significant advances related to the interaction between the psychoanalytic movement and community psychiatry were greatly influenced by the work at the Pavillon Albert-Prévost and the emergence of behavioral therapies (Dr. Yves Lamontagne) and cognitive studies conducted by the Hôpital Louis-H. Lafontaine. Great discoveries about sleep were performed at the Hôpital du Sacré-Coeur de Montréal by teams gathered around Jacques-Yves Montplaisir.We also recall that two ministers from the Quebec government with important political responsibilities were members or directors of the Département de psychiatrie. These are Drs. Camille Laurin and Denis Lazure.The Département aims to strengthen clinical and basic research by contributing new knowledge that will improve care for people with mental disorders. These efforts benefit both patients and the medical students and residents being trained to care for them. The Département remains committed to its program, to pre-doctoral education (ensuring that all medical students at the Université are trained to recognize, diagnose, and be familiar with treatment options for mental disorders), to post-doctoral education for future psychiatrists, and to the care of Quebec's patients.For over 50 years, the academic department has played a key role in attracting and recruiting excellent academic and clinical resources to staff the programs and services of our hospital partners.

    Inuit people (Eskimos) are likely exposed to persistent organochlorine compounds because their traditional diet includes fatty tissues of the arctic marine biota. Here we present the results of organochlorine compound analysis in milk fat samples from artic Quebec Inuit women and in fat tissues from various animal species inhabiting that region. The total concentration of polychlorinated biphenyl congeners in Inuit milk fat was similar to that of the beluga, while the profile of the 10 congeners resembled that of the polar bear. Mean concentrations of various organochlorines in milk-fat samples from Inuit women were between 2 and 10 times greater than those found in samples previously collected from southern Quebec women. The Inuit mothers exhibit the greatest body burden known to occur from exposure to organochlorine residues present in the environment by virtue of their location at the highest trophic level of the arctic food web. 18 refs., 2 tabs.

    Focal mechanisms were determined for 42 small earthquakes (1.4 < M < 3.4) that occurred in the Adirondacks-western Quebec seismic region. The analysis demonstrates the variability of the focal mechanisms and suggests that the region can be divided into two subprovinces with distinctive seismotectonic regimes: (1) in the Adirondacks, the focal mechanisms are mostly strike-slip with a comparatively smaller thrust component and indicate NNE compression: (2) in the western Quebec seismic region, the stress field is more heterogeneous and is dominated by two directions (NE and NW) of horizontal compression. This variable pattern suggests that the seismicity and stress field are controlled by regional plate stresses but are affected by local structures and/or by the predominant orientation of preexisting faults.

    Large organizations often escalate their commitments to mega-project development, even after evidence becomes available of adverse environmental consequences or lack of economic feasibility. This escalation of commitment transcends both sectorial and national boundaries. Preeminent examples include controversial nuclear projects in the US, hydroelectric projects like the Three Gorges Dam in China, and transport projects like the Chunnel and the Concorde. In this article, the authors examine the experience of Hydro-Quebec with the Great Whale Project. They argue that Hydro-Quebec escalated its commitment even after serious questions emerged about its environmental impacts and economic feasibility, because of (1) its earlier success with large projects, (2) its engineering culture`s norms for consistency, and (3) its role in the government`s desire for economic and cultural autonomy. Finally, they discuss the changes that are necessary to break commitments to such projects.

    Research in the field of basic electrophysiology at the Quebec Heart Institute (Laval Hospital, Quebec City, Quebec) has evolved since its beginning in the 1990s. Interests were focused on cardiac arrhythmias induced by drugs, allelic variants and metabolic factors produced during ischemia. The results have contributed to the creation of new standards in drug development, more specifically, testing all new drugs for their potential effects on cardiac potassium currents, which could produce life-threatening proarrhythmic effects. In a French-Canadian population, three heterozygous single nucleotide polymorphisms in hKv1.5, a gene encoding for a major atrial repolarizing current, were found. These variants affect the expression level of the hKv1.5 channel and change the inactivation process in the presence of its accessory beta subunit. Because these effects could shorten atrial action potential, their presence was tested in postcoronary bypass patients and a higher prevalence was found in patients with postoperative atrial fibrillation. Finally, three potentially proarrhythmic factors characteristic of ischemia were identified: pH decrease; oxygen free radicals, which both increase the flow of K+ ions through human ether-a-go-go-related gene and hKv1.5, producing a reduction in action potential duration, frequently leading to cardiac arrhythmias; and lysophosphatidylcholine, a metabolite involved in the production of cardiac arrhythmias early during ischemia that was shown to be a major cause of electrical uncoupling. Over the past decade, the Quebec Heart Institute has provided a significant amount of original data in the field of basic cardiac electrophysiology, specifically concerning arrhythmias originating from pharmacological agents, genetic background and cardiac ischemia.

    Background Cree births in Quebec are characterized by the highest reported prevalence of macrosomia (~35%) in the world. It is unclear whether Cree births are at greater elevated risk of perinatal and infant mortality than other First Nations relative to non-Aboriginal births in Quebec, and if macrosomia may be related. Methods This was a population-based retrospective birth cohort study using the linked birth-infant death database for singleton births to mothers from Cree (n = 5,340), other First Nations (n = 10,810) and non-Aboriginal (n = 229,960) communities in Quebec, 1996–2010. Community type was ascertained by residential postal code and municipality name. The primary outcomes were perinatal and infant mortality. Results Macrosomia (birth weight for gestational age >90th percentile) was substantially more frequent in Cree (38.0%) and other First Nations (21.9%) vs non-Aboriginal (9.4%) communities. Comparing Cree and other First Nations vs non-Aboriginal communities, perinatal mortality rates were 1.52 (95% confidence intervals 1.17, 1.98) and 1.34 (1.10, 1.64) times higher, and infant mortality rates 2.27 (1.71, 3.02) and 1.49 (1.16, 1.91) times higher, respectively. The risk elevations in perinatal and infant death in Cree communities attenuated after adjusting for maternal characteristics (age, education, marital status, parity), but became greater after further adjustment for birth weight (small, appropriate, or large for gestational age). Conclusions Cree communities had greater risk elevations in perinatal and infant mortality than other First Nations relative to non-Aboriginal communities in Quebec. High prevalence of macrosomia did not explain the elevated risk of perinatal and infant mortality in Cree communities. PMID:27517613

    extension that impacts particles never entering that region. What is the gravitational analogue for that situation? The analogue concerns the impact a localized curvature has, and the cone is an excellent example to shed light on that question. Related to the method of images, Stuart has done an enormous amount of work on the influence of topology and curvature on quantum field theory. An example is [17], where the vacuum stress-energy tensor for Clifford-Klein forms of the flat or spherical type were computed. Another strand we would like to mention is Stuart's interest in higher spin equations. In [18], Steven Weinberg wrote down a set of higher spin equations that took his fancy. They involved angular momentum theory, which has always pleased Stuart, and the description was an alternative to Roger Penrose's use of two-spinors. Investigating the inconsistencies that arose on coupling to gauge theories, Stuart extended the classic results in [19], from electromagnetism to gravity in accordance with his general philosophy; see, e.g., [20, 21, 22]. Lately, Stuart is best known for his many applications in the context of zeta function regularization and its applications to quantum field theory under external conditions and spectral theory. He can be considered the world expert on particular case calculations with a knowledge of the literature, old and recent, that is not seen very often and which originated in the many hours spent at different (mostly British) libraries. His attitude towards explicit computations is nicely summarized by himself: 'I have always been interested in exact solutions, even if unphysical, so long as they are pretty. They seem to be working mechanisms that fit together, complete in themselves, like a watch.' The following issue in honour of Stuart's 75th birthday contains contributions that touch upon the various topics he has worked on.

    Background More than 30 exposures in the workplace are proven carcinogens. In the present study, we aimed to estimate the burden of occupational cancer in Quebec so as to increase awareness among stakeholders and to prioritize research activities. Methods Work-attributable fractions—that is, the proportions of cancers attributable to work—as published in Finland and the United Kingdom were applied to Quebec 2002–2006 cancer incidence and mortality data to estimate the number of work-related cases for 28 cancer sites. Results Overall, 6.0% of incident cancers (men: 9.1%; women: 2.7%) and 7.6% of cancer deaths (men: 11.8%; women: 2.8%) could be attributable to work, resulting annually in an average of 2160 new cancer diagnoses and 1190 cancer deaths in Quebec. Incident cancers of the lung, prostate, skin, bladder, and (female) breast were the most numerous; cancer sites resulting in more deaths were lung, (female) breast, and pleura. During the same period, compensation statistics reported annual averages of 94.3 incident cancers and 61.9 cancer deaths, mostly involving mesothelioma (64% of compensated incident cancers) and lung cancer (30% of compensated incident cancers). Conclusions Increased recognition of workplace cancers by all stakeholders, from workers and employers to treating physicians, will foster appropriate preventive measures for safer workplaces.

    Global-scale atmospheric measurements are used to investigate the effectiveness of recent adjustments to production and consumption controls on hydrochlorofluorocarbons (HCFCs) under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) and to assess recent projections of large increases in hydrofluorocarbon (HFC) production and emission. The results show that aggregate global HCFC emissions did not increase appreciably during 2007-2012 and suggest that the 2007 Adjustments to the Montreal Protocol played a role in limiting HCFC emissions well in advance of the 2013 cap on global production. HCFC emissions varied between 27 and 29 kt CFC-11-equivalent (eq)/y or 0.76 and 0.79 GtCO2-eq/y during this period. Despite slower than projected increases in aggregate HCFC emissions since 2007, total emissions of HFCs used as substitutes for HCFCs and chlorofluorocarbons (CFCs) have not increased more rapidly than rates projected [Velders, G. J. M.; Fahey, D. W.; Daniel, J. S.; McFarland, M.; Andersen, S. O. The Large Contribution of Projected HFC Emissions to Future Climate Forcing. Proc. Natl. Acad. Sci. U.S.A. 2009, 106, 10949-10954] for 2007-2012. HFC global emission magnitudes related to this substitution totaled 0.51 (-0.03, +0.04) GtCO2-eq/y in 2012, a magnitude about two times larger than emissions reported to the United Nations Framework Convention on Climate Change (UNFCCC) for these HFCs. Assuming accurate reporting to the UNFCCC, the results imply that developing countries (non-Annex I Parties) not reporting to the UNFCCC now account for nearly 50% of global HFC emissions used as substitutes for ozone-depleting substances (ODSs). Global HFC emissions (as CO2-eq) from ODS substitution can be attributed approximately equally to mobile air conditioning, commercial refrigeration, and the sum of all other applications.

    The MUG (Montreal Urban Community) treatment plant produces approximately 270 tons of dry sludge daily (270 tds/day) during the physico-chemical treatment of wastewater. Recently, this treatment plant endowed a system of drying and granulation of sludge for valorization as an agricultural fertilizer having a capacity of 70 tds/day (25% of the daily sludge production). However, the metal content (mainly Cu and Cd) of the sludge surpasses the norms for biosolids valorization. In order to solve this problem, a demonstration project, from the lab scale to the industrial pilot plant, was carried out to test the Metix-AC technology for the removal of metals. A strongly metal-loaded filtrate was generated during the sludge decontamination. Tests concerned the study of the metal recovery by total precipitation and selective precipitation, as well as the use of alternative products for the metal precipitation. Other works consisted to simulate the acid filtrate recirculation from the decontaminated sludge (25% of the total volume) in the untreated sludge (75% of the total volume) intended for the incineration. The total precipitation with hydrated limeappearedeffectivefortherecoveryof metals (87% Cd, 96% Cr, 97% Cu, 98% Fe, 71% Ni, 100% Pb, 98% Zn). However, this option entails the production of an important quantity of metallic residue, which should be disposed of expensively as dangerous material. The selective iron precipitation does not appear to bean interesting option because the iron in solution within the leached sludge was principally present in the form of ferrous iron, which cannot be precipitated at pH lower than five. On the other hand, the use of commercial precipitating agents (TMT-15, CP-33Z, CP-NB and CPX) without pH adjustment of filtrate gave good results for the recovery of Cu and, to a lesser degree for the recovery of Pb. However, the efficiency for the other metals' (Cd, Cr, Fe, Ni and Zn) recovery was weaker (< 25%). Finally, the acid filtrate

    We monitored survival of 397 radiomarked juvenile American black ducks (Anas rubripes) distributed among Les Escoumins (n = 75) and Kamouraska, Quebec (n = 84), Amherst Point, Nova Scotia (n = 89), and a site on the Vermont-Quebec border (n = 149) during autumn 1990 and 1991. Eighty-six percent (215 of 250) of all confirmed mortalities during the study was from hunting; 72% of marked ducks were shot and retrieved and 14% were shot and unretrieved. We tested for differences in survival in relation to sex, body mass, year (1990-91, 1991-92), and among the 4 locations for each of 2 monitoring periods (early, EMP; late, LMP). With data from the EMP for Vermont-Quebec in 1990 and 1991, Les Escoumins in 1990, and Amherst Point in 1991, survival of hatching-year (HY) males and females did not differ (P = 0.357). For sexes combined for the EMP, survival of ducks was greater in 1991 than 1990 (P = 0.086), and differed among locations (P = 0.013). Survival (years combined) was greater at Amherst Point than at Kamouraska (P = 0.003) and Vermont-Quebec (P = 0.002) during the EMP. The highest survival rate at Amherst Point (0.545 ? 0.056 [SE]) was associated with the latest date (8 Oct) of season opening; the lowest survival rate (0.395 ? 0.043) was at the Vermont-Quebec border, where hunter numbers and activity were greatest. For the LMP, no interaction between years and locations was detected (P = 0.942), and no differences in survival existed between years (P = 0.102) and among locations (P = 0.349). No association was detected between body mass at capture and survival of combined males and females during the EMP (P = 0.572) or during the LMP (P = 0.965). When we censored hunting losses for combined years for each period, EMP or LMP, all survival estimates exceeded 0.800 (0.809-0.965). These data emphasize need for an improved harvest strategy for American black ducks in North America to allow for increases in breeding populations to achieve population goals.

  8. Analysis of air pollution from swine production by using air dispersion model and GIS in Quebec.

    Swine production, the second most important contributor to Quebec's agricultural revenue, faces many problems. Intensive piggeries, with up to 599 animal units, are used to raise finishing pigs for slaughter. Among the great number of gaseous species emitted to the atmospheric environment from livestock buildings and manure storage units is NH3, which is one of the most important and most offensive with respect to human health. Under appropriate meteorological and topographical conditions, gaseous contaminants can spread and cause a public nuisance--up to a 1-km radius around the farm. To mitigate these effects, the Quebec Government adopted regulations that set minimum buffer distances to be observed by any expansion of an existing or new pig farm. The objectives of this study were (i) to assess the efficiency of the current buffer distance prescriptions in Quebec in mitigating effects of air pollution from swine units and (ii) to identify potential areas for establishing pig farm operations that will not be offensive to people. The air dispersion American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) with receptors distributed at 1.6 km around each source was used first, followed by a spatial geographic information system (GIS) model. Results from the dispersion model showed that the highest hourly concentration with a 99.5% compliance frequency for a single farm was 3078.1 microg/m3 and exceeded the NH3 odor criterion hourly standard set by the Quebec Government at 183.4 microg/m3. Thus, for public safety, densely populated areas like housing developments must be located >1300 m from a pig farm. This distance is in the range of setback distances (723 to 1447 m) obtained by using abacuses defined in the L'Erable Regional County Municipality. That is why we can say the current rules established by the Quebec Government, if rigorously applied, can prevent odor nuisance, due to NH3 emission, from swine farms. In the spatial model

    The significant eruptions of Okmok and Kasatochi volcanoes in July and August 2008 produced large volcanic clouds consisting in a mixture ash, sulphur dioxide, sulphuric acid and sulphate aerosols that moved from the Aleutians over the North Pacific, North America, the Atlantic Ocean and eventually around the globe over a period of a few weeks. The three North American designated Volcanic Ash Advisory Centers (VAAC) and Meteorological Watch Offices worked in close collaboration with the Alaska Volcano Observatory to issue guidance and warnings (SIGMET) to the aviation community regarding the location and displacement of the volcanic clouds throughout this event. The Montreal VAAC was heavily involved in this coordination effort as the volcanic clouds approached and entered Canadian airspace. Atmospheric transport and dispersion modeling (ATDM) is an important tool in this process to help diagnose and predict the motion of volcanic clouds. This is even more important for long-lived events, as was the case here, given the complexity of atmospheric flows and dynamics in time and space which resulted in equally complex volcanic cloud dispersion patterns. In this study, we present the ATDM results for both eruptions using a lagrangian model called "Modele Lagrangien de Dispersion des Particules" (MLDP0) and developed at the Canadian Meteorological Centre. The model is the process of being implemented for the Montreal VAAC operations. The modeling results are compared with measurements and imagery from various satellites and sensors such as GOES, POES, AIRS and OMI.

    Background: For evidence-based medical practice, well-defined risk scoring systems are essential to identify patients with a poor prognosis. The objective of this study was to develop a prognostic score, the Montreal prognostic score (MPS), to improve prognostication of patients with incurable non-small cell lung cancer (NSCLC) in everyday practice. Methods: A training cohort (TC) and a confirmatory cohort (CC) of newly diagnosed patients with NSCLC planning to receive chemotherapy were used to develop the MPS. Stage and clinically available biomarkers were entered into a Cox model and risk weights were estimated. C-statistics were used to test the accuracy. Results: The TC consisted of 258 patients and the CC consisted of 433 patients. Montreal prognostic score classified patients into three distinct groups with median survivals of 2.5 months (95% confidence interval (CI): 1.8, 4.2), 8.2 months (95% CI: 7.0, 9.4) and 18.2 months (95% CI: 14.0, 27.5), respectively (log-rank, P<0.001). Overall, the C-statistics were 0.691 (95% CI: 0.685, 0.697) for the TC and 0.665 (95% CI: 0.661, 0.670) for the CC. Conclusion: The MPS, by classifying patients into three well-defined prognostic groups, provides valuable information, which physicians could use to better inform their patients about treatment options, especially the best timing to involve palliative care teams.

  11. The potential modal shift and health benefits of implementing a public bicycle share program in Montreal, Canada

    PubMed Central

    2013-01-01

    Background This study estimated the modal shift associated with the implementation of a public bicycle share program in Montreal, Canada. Methods A population-based sample of adults participated in two cross sectional telephone surveys. Self-reported travel behaviors were collected at the end of the first (fall 2009) and second (fall 2010) season of implementation. The sample included 2502 (Mean age=47.8 years, 61.8% female), and 2509 (Mean age=48.9 years, 59.0% female) adult respondents in each survey. Results The estimated modal shift associated with the implementation of the PBSP from motor vehicle use to walking, cycling, and public transportation was 6483 and 8023 trips in 2009 and 2010. This change represents 0.34% and 0.43% of all motor vehicle trips in Montreal. Conclusions The implementation of a PBSP was associated with a shift toward active transportation. The modal shift was complex and not simply the result of a discrete shift from one mode to another. Promotion of active transportation should encourage integration of multiple active transportation modes to better reflect people’s actual transportation behaviors. PMID:23705934

    The stratospheric ozone layer protects the surface of the Earth from harmful ultraviolet (UV-B) radiation, which has been causally linked to skin cancer and cataracts, suppression of the human immune system, damage to crops and aquatic organisms, the formation of ground-level zone and the rapid weathering of outdoor plastics. In recent years, scientists have observed a significant deterioration of the ozone layer, particularly over the poles, but increasingly over populated regions as well. This deterioration has been attributed to the atmospheric release of certain man-made halocarbons, including chlorofluorocarbons (CFCs), halons, methyl chloroform and carbon tetrachloride. Once used extensively as propellants for aerosol sprays (but generally banned for such purposes since 1978), CFCs are widely used today as refrigerants, foams and solvents. All of these chlorinated (CFC, methyl chloroform and carbon tetrachloride) and brominated (halon) compounds are classified for regulatory purposes as Class I substances because of their significant ozone-depleting potential. Hydrochlorofluorocarbons (HCFCs), developed as alternatives to CFCs and halons for many different applications, have been classified for regulatory purposes as Class II substances because of their relatively less destructive impact on stratospheric ozone. This paper describes the following regulations to reduce destruction of the ozone layer: the Montreal Protocol; Title VI of the Clean air Act Amendments of 1990; Accelerated Phase-out schedules developed by the countries which signed the Montreal Protocol; Use restrictions; Recycling and Emission reduction requirements; Servicing of motor vehicle air conditions; ban on nonessential products; labeling requirements; safe alternatives. 6 refs.

    nationwide effort for the Clean Development Mechanism project benefit of the Kyoto protocol. Emission rates of the halocarbons determined from the empirical emission strengths will certainly vary according to emission trend of our reference species, HCFC-22 in China from 2008 and 2012. Annual and average of HCFC-22 emissions from 2008 to 2012 will be calculated with an inverse method based on FLEXPART transport model. More detailed discussion on the emission rate estimation and its related caveats will be made in the presentation, but overall our analysis highlights the significance of long-term continuous monitoring for CFCs, HCFCs and HFCs in China to investigate impacts of Montreal Protocol regulations.

    Objective: To determine the prevalence and factors associated with nonmedical use of prescription medication (NMUPM) among adolescents who use drugs (ages 12 to 17 years) in Quebec. Method: Secondary data analyses were carried out with data from a 6-month study, namely, the 2010–2011 Quebec Health Survey of High School Students—a large-scale survey that sought to gain a better understanding of the health and well-being of young Quebecers in high school. Bivariate and multivariate logistic regression analyses were conducted to study NMUPM among adolescents who use drugs, according to sociodemographic characteristics, peer characteristics, health indicators (anxiety, depression, or attention-deficit disorder [ADD] with or without hyperactivity), self-competency, family environment, and substance use (alcohol and drug use) factors. Results: Among adolescents who had used drugs in the previous 12 months, 5.4% (95% CI 4.9% to 6.0%) reported NMUPM. Based on multivariate analyses, having an ADD (adjusted odds ratio [AOR] 1.47; 95% CI 1.13 to 1.91), anxiety disorder (AOR 2.14; 95% CI 1.57 to 2.92), low self-esteem (AOR 1.62; 95% CI 1.26 to 2.08), low self-control (AOR 1.95; 95% CI 1.55 to 2.45), low parental supervision (AOR 1.43; 95% CI 1.11 to 1.83), regular alcohol use (AOR 1.72; 95% CI 1.36 to 2.16), and polysubstance use (AOR 4.09; 95% CI 3.06 to 5.48) were associated with increased odds of reporting NMUPM. Conclusions: The observed prevalence of NMUPM was lower than expected. However, the associations noted with certain mental health disorders and regular or heavy use of other psychoactive substances are troubling. Clinical implications are discussed. PMID:26720824

    1996-01-01

    OBJECTIVE: To examine what role demographic factors and increases in physician fees and utilization played in the rise in costs of physician services provided for elderly people in Quebec between 1982 and 1992, and to investigate changes in patterns of care (type and amount of services) related to utilization. DESIGN: Retrospective study of population-based data. SETTING: Province of Quebec. SUBJECTS: Elderly people (65 years of age and over) in Quebec in 1982 (n = 589,800) and in 1992 (n = 803,600). OUTCOME MEASURES: Proportion of the increase in physician care costs attributable to (a) aging (defined as a shift in the age distribution) of the elderly population, (b) the increase in the size of the elderly population, (c) the increase in physician fees and (d) the increase in utilization of physician services; proportion of care provided by general practitioners (GPs) and by specialists; proportion of minor and complete examinations provided by GPs; and rates of hospital admissions and surgery. RESULTS: Aging was responsible for 0.5% of the increase in physician care costs between 1982 and 1992, population growth for 27.0% and the increase in physician fees for 25.5%. The increased utilization accounted for 47.0% of the total cost increase. Analyses of the utilization data revealed a shift toward more costly services, more visits to specialists and higher rates of hospital admissions and surgery in 1992 than in 1982. CONCLUSIONS: Aging and population growth had minor effects on the increase in physician care costs between 1982 and 1992. Increased utilization was the most important factor. The appropriateness of this trend needs to be verified. PMID:8956832

    During the summer of 2012, a major Legionella pneumophila serogroup 1 outbreak occurred in Quebec City, Canada, which caused 182 declared cases of Legionnaire's disease and included 13 fatalities. Legionella pneumophila serogroup 1 isolates from 23 patients as well as from 32 cooling towers located in the vicinity of the outbreak were recovered for analysis. In addition, 6 isolates from the 1996 Quebec City outbreak and 4 isolates from patients unrelated to both outbreaks were added to allow comparison. We characterized the isolates using pulsed-field gel electrophoresis, sequence-based typing, and whole genome sequencing. The comparison of patients-isolated strains to cooling tower isolates allowed the identification of the tower that was the source of the outbreak. Legionella pneumophila strain Quebec 2012 was identified as a ST-62 by sequence-based typing methodology. Two new Legionellaceae plasmids were found only in the epidemic strain. The LVH type IV secretion system was found in the 2012 outbreak isolates but not in the ones from the 1996 outbreak and only in half of the contemporary human isolates. The epidemic strains replicated more efficiently and were more cytotoxic to human macrophages than the environmental strains tested. At least four Icm/Dot effectors in the epidemic strains were absent in the environmental strains suggesting that some effectors could impact the intracellular replication in human macrophages. Sequence-based typing and pulsed-field gel electrophoresis combined with whole genome sequencing allowed the identification and the analysis of the causative strain including its likely environmental source.

    PubMed

    Laberge, Anne-Marie

    2007-11-01

    The prevalence and distribution of genetic diseases in the province of Quebec has been influenced by its population history. The current French Canadian population stems from 8,500 pioneers who left France for Nouvelle-France between 1608 and 1759. After the English conquest of Nouvelle-France in 1759, the French Canadian population remained mostly genetically isolated, for linguistic, cultural, and religious reasons. The migration of a small number of French individuals to Nouvelle-France created a founder effect. Subsequent migrations inland have created smaller regional founder effects. The limited size of the population favoured genetic drift, and the social context encouraged endogamy, i.e. unions between French Canadians with little admixture with English and other immigrants. Founder effects, genetic drift, and endogamy have all played a role in the current prevalence and distribution of genetic diseases now found in Quebec. The prevalence and distribution of genetic diseases in Quebec need to be taken into account in clinical practice. When clinicians are knowledgeable about the genetic diseases prevalent in the population they treat, they know to consider these diseases in differential diagnoses when appropriate and prioritize investigations accordingly. When developing a new diagnostic test for a genetic disease, the prevalence of the disease and the nature of the mutations found in the target population need to be taken into account. The performance of the test will depend on how well it accounts for the particularities of the disease in that population. In other words, how well does it detect the mutations found in that population? Interpretation of individual genetic test results will also depend on how well the test is expected to perform in the individual's population. PMID:18021714

    Porcine respiratory coronavirus (PRCV) was identified for the first time in Quebec, using a blocking enzyme-linked immunosorbent assay (ELISA). Unlike the virus neutralization test (VNT), this ELISA was able to distinguish transmissible gastroenteritis virus (TGEV) from PRCV. Among the 15 seropositive fattening herds from group A, sera containing PRCV antibodies represented 74.8%, whereas those with TGEV antibodies represented only 7.2%. In group B, which consisted of 15 sow herds, nine herds expressed only PRCV-specific antibodies while the other herds had animals positive for TGEV-specific antibodies. PMID:17424115

    Bottom-up estimates from targeted field campaigns can provide important insight into fine-scale source emissions not captured by regular gas monitoring. In turn, these targeted data sets can shed new light on the effectiveness of environmental policies. Halocarbons regulated under the Montreal Protocol are important due both to their high global warming potential and destruction of the stratospheric ozone layer. Although the Montreal Protocol has been in effect in industrialized countries for over a decade, observation- based estimates continue to report lingering emissions of regulated halocarbons. Lack of data apportioning emissions of Montreal Protocol-regulated gases to individual sources has led to wide-ranging assumptions about the source of lingering halocarbon emissions. In particular, landfill emissions have been the subject of some controversy with the landfill source reported to be 0-100% of total halocarbon emissions in industrialized countries. This study provides the first comprehensive observation-based estimates of CFC-12, CFC-11, CFC-113, and CH3CCl3 emissions in the United States (US) and United Kingdom (UK) from municipal solid waste (MSW) landfills. Whole landfill mixing ratios and flow rates were sampled monthly at one US landfill to provide temporal coverage. Spatial coverage was achieved through one time sampling at seven US landfills and through data provided by nine UK landfills. Weighted linear least square regressions of generated halocarbon vs. CH4 were used in combination with national estimates of landfill CH4 emissions to estimate 2006 US and UK landfill halocarbon emissions. For all four halocarbons, 2006 US landfill emissions were ~ 0.6% (0.008 - 0.08 Gg/year) of total US emissions from all sources. The 2006 UK landfill emission estimates were 6% (0.03 Gg/year) and 0.8% (0.006 Gg/year) of total UK CFC-12 and CFC-11 emissions, respectively, indicating that landfill emissions may be a significant source of CFC-12 in the UK.

    1988-08-01

    This paper is about alternative chemicals. The substitution, of less ozone-depleting chemicals wherever it is cost effective and technically feasible, is expected because of anticipated future limitations on production and consumption of the fully halogenated chlorofluorocarbons (CFCs) and halons (fluorocarbons containing bromine atoms) covered by the Montreal Protocol. Certain alternative chemicals (e.g., HCFC-22 and methyl chloroform) are already used in applications other than as CFC substitutes. Projected future consumption of alternative chemicals includes such non-substitution use. Study results indicate that the 50% reduction in weighted CFC/halon consumption (weighted for ozone-depletion potential) required by the Protocol in 1998 could initially be achieved by alternative chemicals alone. However, alternative processes or products not requiring either the controlled substances or their substitute chemicals and/or substantial recovery and reuse of the chemicals would be needed to maintain the 50% level of reduction in the longer term.

    The study was designed to identify factors associated with the diversity of professionals consulted by 212 individuals affected by at least one mental disorder in the past 12 months in a Montreal catchment area. For inclusion in the study, participants had to be aged 15 to 65 and reside in the study zone. A comprehensive set of variables were analyzed in accordance with the Andersen’s behavioural model of health service use. General practitioners, psychiatrists, and psychologists were the main professionals consulted in this study. Having post-secondary education, more than a single mental disorder, excellent relationships with neighbours, and (marginally) being a lifelong victim of violence were associated with higher numbers of professionals consulted. As this study highlights the large number of diversified professionals consulted for reason of mental disorders, shared care initiatives may prove beneficial. Greater effort could also be made in increasing services toward those deemed more vulnerable. PMID:22980229

    In the past three decades, rapidly changing demographic characteristics have been witnessed in western society. Concurrently, numerous culture-related studies have attested to the disparity in health services among different ethnic groups. Reports have shown contributing factors that can render main stream services inaccessible to immigrants include cultural and language barriers, adaptation difficulties, racial discrimination and lack of culturally appropriate psychosocial services. Inadequate training of health professionals regarding cross-cultural issues may hinder patient compliance and therapeutic alliances. In a paediatric practice in Montreal, prevalent health problems among Chinese families were identified to be related to cultural beliefs and psychosocial factors. These included a low breastfeeding rate (8%) among Chinese newborns, prevalent iron deficiency anemia (12%), nursing caries, social isolation, delayed diagnosis of developmental delay, learning disabilities and psychosocial problems. The participation in community research and advocacy, the development of health promotional projects with an interdisciplinary approach and the preparation of Chinese health information such as perinatal programs, infant nutrition, dental hygiene and immunization, were described. Subsequent studies in this population illustrated an increased breastfeeding rate (48%), decreased incidence of iron deficiency (2.8%) and improved self-health maintenance practices. More culturally appropriate allied health services, including the Multiculturalism Department in the Montreal Children's Hospital, have subsequently been developed for the community.In summary, identifying prevalent health problems of ethnic propensity may be the initiatives needed to develop research and health promotional projects for a target population. Comprehensive health care to different ethnic groups requires health professionals to incorporate cross-cultural issues in their services. PMID:19675850

    Methylcyclopentadienyl manganese tricarbonyl (MMT) is an organic derivative of manganese (Mn), used since 1976 in Canadian gasoline as an octane enhancer. Its combustion leads to the emission of Mn particles. Several studies carried out by our research group have established a correlation between atmospheric Mn concentrations and automobile traffic density, suggesting that MMT in gasoline could play a significant role. This study aims to measure Mn concentrations in the air of the underground subway in Montreal (Canada) and to examine the relation with nearby surface automobile traffic density and, by extension, with the use of MMT in gasoline. Three subway stations were chosen for their location in different microenvironments with different traffic densities. Respirable (MnR<5 microm) and total Mn (MnT) were sampled over two weeks, 5 days/week, 12 h/day. For the station located in the lower traffic density area, relatively low levels of MnR and MnT were found, with averages of 0.018 and 0.032 microg/m(3), respectively. These concentrations are within the range of the background levels in Montreal. For the other two stations, the average concentrations of MnR were twice as high and exceeded the US EPA reference concentration of 0.05 microg/m(3). Although there may be several sources of Mn from different components of the subway structure and vehicles, no correlation was found between subway traffic and atmospheric Mn in the subway. Since the air in the underground subway is pumped directly from outside without filtration, our findings strongly suggest that the combustion of MMT in automobiles is an important factor.

    In the last twenty years polychlorinated biphenyls (PCBs) have been identified as major contaminants of the natural environment. More recently, the presence of such toxic compounds was described in arctic regions. In this regions, PCBs have been found in water, snow, ice and air. The level of PCB contamination was significantly lower than that found at midlatitudes. PCB levels are often monitored because they could also reflect exposure to several other chemical contaminants such as other organochlorines. Other highly toxic compounds such as polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) were found in the blubber from arctic ringed seals caught near the west coast of Spitzbergen. Since the closest known sources of PCDD and PCDF were several thousands of kilometers away, these results were surprising. The consumption of fish and marine mammals by the Inuit people is markedly higher than in the rest of the Canadian population and in some communities, sea mammals represent a significant part of the diet. It is possible that Inuit are exposed to an undesirably high of PCBs and other organochlorinated compounds. Levels of PCBs in the Inuit diet were assessed in Broughton Island, North West Territories, Canada. The present study was designed to assess the PCB levels in the breast milk of lactating Inuit women from the Hudson Bay region of Northern Quebec and of women from Southern Quebec.

    1995-12-31

    Hydro-Quebec is in the process of renewing its Energy Management System (EMS) and its SCADA. Part of this work involves the introduction of a new data acquisition architecture. The proposed architecture requires that many systems now in operation be modified. This article describes a specialized Testing Workstation (TW) which provides all the testing capabilities needed to validate the full operation of the systems in the new communications environment. These include RTUs, other acquisition systems and even the new SCADA/EMS itself. The TW offers an extensive set of tools: communications analyzer, application data monitor, automatic and script-based simulators, allowing full testing of any system using the communications protocol of the new SCADA/EMS. The testing can be either at the communications level or at the application level. Since the TW has full database capabilities for field data, it can act both as a client (SCADA) and as a server (e.g. RTU). For Hydro-Quebec, the TW offers the advantage of standardizing the testing process used during the development of the new systems. The use of universal test equipment facilitates the integration of all systems into the new SCADA/EMS environment.

    OBJECTIVES: This study documented the concentration of polychlorinated biphenyls (PCBs) and dichlorodiphenyl dichloroethylene (DDE) in the breast milk of women from Quebec, Canada, and assessed the impact of various sociodemographic and lifestyle factors on these levels. METHODS: From 1988 to 1990, milk samples were obtained from 536 Quebec women and analyzed for seven PCB congeners and p,p'-DDE. Information was obtained on subjects' physical, sociodemographic, and lifestyle characteristics. RESULTS: Mean concentrations were 0.52 mg/kg lipids (95% confidence interval [CI] = 0.50, 0.54) and 0.34 mg/kg lipids (95% CI = 0.32, 0.35) for PCBs (Aroclor 1260) and DDE, respectively. Age and history of breast-feeding showed statistically significant correlations with PCB and DDE concentrations. CONCLUSIONS: Concentrations of PCBs and DDE measured in this study are at the lower end of the concentration range recently reported for women living in industrialized countries. The modulating factors identified here should be considered when conducting studies on organochlorine exposure and disease. PMID:8806375

    Objective Recent literature shows growing interest in the values displayed by occupational therapists. Yet, none of these writings has so far examined the factors that contribute to the development of occupational therapists' professional values. These factors are important, since values play a pivotal role in forging professional identity, which in the case of some occupational therapists remains somewhat ambiguous. This article proposes possible answers to the following question: What do Quebec Francophone occupational therapists perceive as the building blocks of their professional values? Methods Using a phenomenological qualitative method, the subjective experience of occupational therapists in Quebec, Canada was examined. Twenty-six occupational therapists took part in the study. Results As intended, their professional experience was varied. According to the participants, four factors contributed significantly to their professional values: professional experience, university training, personal experience, and professional development. However, fewer than 50% of the participants cited six other factors (workplace, family upbringing, personal development, personality and abilities, professional normative framework, and sociocultural background). Conclusions Most of these results are consistent with those documented in existing works. They point to the relevance of discussing professional values during university training and continuing professional development, as well as encouraging occupational therapists to become exemplars for their colleagues and interns. This study constitutes an initial step in understanding how occupational therapists' axiological identity is formed. PMID:26824179

    The Quebec Health Smart Card Project is advocating the use of a memory card software server[1] (SCAM) to implement a portable medical record (PMR) on a smart card. The PMR is viewed as an object that can be manipulated by SCAM's services. In fact, we can talk about a pseudo-object-oriented approach. This software architecture provides a flexible and evolutive way to manage and optimize the PMR. SCAM is a generic software server; it can manage smart cards as well as optical (laser) cards or other types of memory cards. But, in the specific case of the Quebec Health Card Project, SCAM is used to provide services between physicians' or pharmacists' software and IBM smart card technology. We propose to expose the concepts and techniques used to provide a generic environment to deal with smart cards (and more generally with memory cards), to obtain a dynamic an evolutive PMR, to raise the system global security level and the data integrity, to optimize significantly the management of the PMR, and to provide statistic information about the use of the PMR.

    Purpose Bullying has become a significant public health issue, particularly among youth. This study documents cyberbullying, homophobic bullying and bullying at school or elsewhere and their correlates among both heterosexual and sexual-minority high school students in Quebec (Canada). Method A representative sample of 8,194 students aged 14–20 years was recruited in Quebec (Canada) high schools. We assessed cyberbullying, homophobic bullying and bullying at school or elsewhere in the past 12 months and their association with current self-esteem and psychological distress as well as suicidal ideations. Results Bullying at school or elsewhere was the most common form of bullying (26.1%), followed by cyberbullying (22.9%) and homophobic bullying (3.6%). Overall, girls and sexual-minority youth were more likely to experienced cyberbullying and other form of bullying as well as psychological distress, low self-esteem and suicidal ideations. The three forms of bullying were significantly and independently associated with all mental health outcomes. Conclusions The results underscore the relevance of taking into account gender and sexual orientation variations in efforts to prevent bullying experience and its consequences. PMID:26047959

    In 2006, the golden cyst nematode, Globodera rostochiensis, was discovered in the province of Quebec, Canada. We report here the life cycle of G. rostochiensis under the climatic conditions of southwestern Quebec. Only one full generation was completed per year under these latitudes. On susceptible potato cv. Snowden, G. rostochiensis needed a minimum of 579 growing degree units (GDU) (base 5.9°C) to complete its life cycle and the first mature cysts were observed 42 to 63 days after planting (DAP). In soil, second-stage juveniles (J2) were first observed 14 to 21 DAP, whereas both white females on roots and males in soil appeared synchronously after 35 to 42 days. The duration of the life cycle was affected by temperature but not by soil type. A second wave of hatching systematically occurred later in the season and a second generation of males was observed during the 2011 growth season. No complete second cycle was observed before plant senescence. Climate change and later maturing cultivars/crops could allow the development of a full second generation in the future. PMID:26941456

    Objectives. The objectives of this study were to examine the spatial accessibility to alcohol outlets in Quebec and to assess the association between neighborhood level characteristics and availability of alcohol outlets. Methods. The Tobit Model was used to assess the association between neighborhood level characteristics and the availability of alcohol outlets within 500, 1000, 2000, and 3000 metres, respectively. Results. Alcohol outlets were found to be most available in the two largest metropolitan areas of the province of Quebec (Montréal and Québec City). Within 1000 metres, alcohol outlets are more available in neighbourhoods with the following characteristics: highest concentration of men, least materially deprived highest concentration of persons aged 20 years or more, and location either in a metropolitan area or in a small town. Finally, the number of bars with video lottery terminals increases with the level of social and material deprivation. Conclusion. In Québec, there is no rule governing the location of alcohol outlets. Thus, there is an abundant literature indicating that the regulation of alcohol outlet density could be an effective means of controlling risk attributable to alcohol consumption. PMID:25810946

    Rotation crop experiments were conducted from 1998 to 2000 to assess the impact of forage and grain pearl millet (Pennisetum glaucum) on Pratylenchus penetrans populations in three potato (Solanum tuberosum cv. Superior) fields in Quebec. These crops were compared to oats and(or) barley. Forage millet had a suppressive effect on P. penetrans populations after a 1 year rotation. The following year, marketable potato yields were negatively correlated with initial P. penetrans densities on two experimental sites (r = -0.454, P = 0.044; r = -0.426, P = 0.017). Average marketable and total yields were increased by 10% in plots previously grown in forage millet hybrid CFPM 101 when compared to oats (P = 0.017). Damage functions between preplant nematode density (Pi) and marketable yield (y = 42.0 -4.091 log₁₀ [Pi + 1]) and total yield (y = 43.9 -4.039 log₁₀ [Pi + 1]) of potato were established on pooled yield data. Forage pearl millet is an efficient and economically viable alternative for managing root-lesion nematodes and improving potato yields in Quebec. PMID:19262846

    Originally designed in Quebec, the MOI project was a collaboration between two professors of social work from Quebec and two members of the Peruvian NGO called SUR in Villa de Salvador, one of poorest slum areas on the outskirts of Lima. The approach is founded on the notion that the body is the primary instrument through which a person can interact with the world around him or her, and that the physical and mental health of an individual exists within the context of healthy conditions of life that must include at least a basic social and health infrastructure as well as healthy hygiene practices on the part of individuals, families and the local community. Preschool children (ages 4-6), study a different part of the body and its proper care each week through classroom observation games. Parents' help is requested to modify unhealthy conditions, at the same time to enrich the children's experience and to mobilize the community to improve health conditions. During the 1991 cholera epidemic, not a single case was counted in the experimental district, despite its clearly socio-economically impoverished status, and despite the fact that the Ministry of Health recorded 86,650 cases in the Lima-Callao district, accounting for about 40% of the total number of cases in the Peru. The prior work made it easier to explain how cholera is spread and what special new measures needed to be taken in addition to the hygiene habits already taught.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7820377

    Engineered NanoMaterials (NM) offer an opportunity to develop a wide variety of new products with unique properties but many studies have shown potential OHS risks specific to NM. Addressing these risks requires knowledge about release of NM into the workplaces. This research aimed to map the state of nanotechnology OHS practices in Quebec through a questionnaire following a first contact by telephone when possible and by compiling the type and volumes of NM used as well as gathering information related to the working conditions and OHS aspects. This survey was conducted among 1310 Quebec industries and 653 researchers working in different specialties potentially involved in the development/production/distribution/integration of NM and use of NM containing products. Overall, 90 questionnaires, including 51 from the industries, were completed. These showed that NM are mainly used into the powder form, in many different sectors and deserve a wide range of markets. The prevention measures implemented vary widely from a workplace to another but about one third of the participants report that they have implemented NP adapted prevention measures but they remain worried on some specific operations. More than 50% of the participants request more information about the safe laboratory/plant design, toxicity, regulation, good work practices and prevention measures, efficiency of personal protective equipment and environmental impacts.

    The Second International Workshop 'SANS-YuMO User Meeting at the Start-up of Scientific Experiments on the IBR-2M Reactor', devoted to the 75th anniversary of the birth of Professor Yu M Ostanevich (1936-1992), an outstanding neutron physicist and the founder of small-angle neutron scattering (field, group, and instrument) at JINR FLNPh, was held on 27-30 May at the Frank Laboratory of Neutron Physics. The first Workshop was held in October 2006. Research groups from different neutron centers, universities and research institutes across Europe presented more than 35 oral and poster presentations describing scientific and methodological results. Most of them were obtained with the help of the YuMO instrument before the IBR-2 shutdown in 2006. For the last four years the IBR-2 reactor has been shut down for refurbishment. At the end of 2010 the physical launch of the IBR-2M reactor was finally realized. Nowadays the small-angle neutron scattering (SANS) technique is applied to a wide range of scientific problems in condensed matter, soft condensed matter, biology and nanotechnology, and despite the fact that there are currently over 30 SANS instruments in operation worldwide at both reactor and spallation sources, the demand for beam-time is considerably higher than the time available. It must be remembered, however, that as the first SANS machine on a steady-state reactor was constructed at the Institute Laue Langevin, Grenoble, the first SANS instrument on a 'white' neutron pulsed beam was accomplished at the Joint Institute for Nuclear Research at the IBR-30 reactor, beamline N5. During the meeting Yu M Ostanevich's determinative and crucial contribution to the construction of spectrometers at the IBR-2 high-pulsed reactor was presented, as well as his contribution to the development of the time-of-flight (TOF) small-angle scattering technique, and a selection of other scientific areas.

    Objective To investigate whether the 1998 government policy for mandatory fortification of flour and pasta products with folate was followed by a reduction in the prevalence of severe congenital heart defects. Design Time trend analysis. Setting Province of Quebec, Canada. Participants Infants born in 1990-2005 identified with severe congenital heart defects (tetralogy of Fallot, endocardial cushion defects, univentricular hearts, truncus arteriosus, or transposition complexes) in Quebec administrative databases. Methods Data analysed in two time periods (before and after fortification). Birth prevalence measured annually as infants (live and stillbirths) with severe congenital heart defects per 1000 births in Quebec. Changes in the birth prevalence from the period before to the period after fortification were estimated with Poisson regression. Results Among the 1 324 440 births in Quebec in 1990-2005 there were 2083 infants born with severe congenital heart defects, corresponding to an average birth prevalence of 1.57/1000 births. Time trend analysis showed no change in the birth prevalence of severe birth defects in the nine years before fortification (rate ratio 1.01, 95% confidence interval 0.99 to 1.03), while in the seven years after fortification there was a significant 6% decrease per year (0.94, 0.90 to 0.97). Conclusions Public health measures to increase folic acid intake were followed by a decrease in the birth prevalence of severe congenital heart defects. These findings support the hypothesis that folic acid has a preventive effect on heart defects. PMID:19436079

    Abstract Twig beetles in the genus Pityophthorus Eichhoff, 1864 include more than 300 species worldwide, with maximum diversity in tropical and subtropical regions. To date, approximately 50 species of Pityophthorus have been recorded in Canada, and these species are associated mainly with coniferous trees. Since 1981, no comprehensive study on this difficult taxonomic group has been conducted in Quebec, Canada, most likely due to their limited significance as forest pests. Based on data gathered from five years of field sampling in conifer seed orchards and compiled from various entomological collections, the distribution of Pityophthorus species in Quebec is presented. Approximately 291 new localities were recorded for the Pityophthorus species. Five species-group taxa, namely Pityophthorus puberulus (LeConte, 1868), Pityophthorus pulchellus pulchellus Eichhoff, 1869, Pityophthorus pulicarius (Zimmermann, 1868), Pityophthorus nitidus Swaine, 1917,and Pityophthorus cariniceps LeConte&Horn, 1876 were the most widespread. In contrast, Pityophthorus consimilis LeConte, 1878, Pityophthorus intextus Swaine, 1917, Pityophthorus dentifrons Blackman, 1922, Pityophthorus ramiperda Swaine, 1917, and Pityophthorus concavus Blackman, 1928 display a notably limited distribution. In addition, the first distribution records of Pityophthorus intextus and Pityophthorus biovalis Blackman, 1922 are furnished, and the subspecies Pityophthorus murrayanae murrayanae Blackman, 1922is reported from Quebec for the second time. Moreover, distribution maps are provided for all Pityophthorus species recorded in the province of Quebec. PMID:24294076

    The incidence of Kawasaki disease in Maghreb countries is apparently low, unlike those living in the province of Quebec, Canada. This retrospective study compared Maghrebi children living in Quebec to the countries of origin, Morocco, Algeria, and Tunisia. The annualized incidence rate in Quebec (18.49/year/100 000 children under 5 years of age) was 4 to 12 times higher than in Tunisia, Morocco, and Algeria (0.95, 4.52, and 3.15, respectively). The prevalence of incomplete diagnostic criteria was higher in Quebec at 39%, Morocco 43%, and Tunisia 39% compared to Algeria at 8%, with minimal delayed diagnosis (7%) only in Quebec compared to 30%, 35%, and 62%, respectively (P < .001). The rate of coronary aneurysms was comparable however (11% in Quebec vs 4%, 10%, and 25%, in Tunisia, Morocco, and Algeria, respectively; P = .31). The higher incidence of Kawasaki disease in the Maghreb community in Quebec versus the countries of origin seems due to underdiagnosis, which represents a public health concern in those countries.

    The style of Taconian deformation and metamorphism varies significantly along strike from the Quebec reentrant toward the New York promontory. Comparison of Upper Proterozoic/Lower Cambrian pre-shelf sedimentary sequences between southern Quebec and central Vermont suggests that, despite important similarities, the configurations of the rifted continental crust differed along strike. In southern Quebec, the base of the rift sequence is characterized by extensive flood basalt volcanism (Tibbit Hill Fm.). The basaltic rocks were subsequently deformed by block-faulting, which acted as basement to overlying rift-clastic sediments. In central Vermont, mafic dikes cut the Middle Proterozoic Lincoln massif and are unconformably overlain by the basal rift sequence. In both areas, a hinge zone, marking the transition between relatively unsubsided and significantly attenuated continental crust, developed early in the sedimentation history. West of the hinge zone, the basal rift-clastic rocks are characterized by a relatively thin sequence indicative of shallow subaqueous to subaerial deposition (Pinnacle Fm.), capped by a dolomitic horizon (White Brook Fm. and Forestdale Mb.) and a disconformity marking renewed extension. East of the hinge zone, rift-clastic rocks are thicker, generally finer-grained, and commonly contain mafic rocks of tholeiitic affinity. In southern Quebec and northern Vermont, significant subsidence accompanied the post-White Brook/Forestdale episode of extension. In contrast, the basement high of the Lincoln massif remained largely unsubsided until the onset of thermal subsidence in the Early Cambrian. Both in southern Quebec and central Vermont, early Taconian deformation was characterized by sub-horizontal westward transport of distal clastic sedimentary rocks.

    Background: Predicted rise in global mean temperature and intensification of heat waves associated with climate change present an increasing challenge for occupational health and safety. Although important scientific knowledge has been gathered on the health effects of heat, very few studies have focused on quantifying the association between outdoor heat and mortality or morbidity among workers. Objective: To quantify the association between occupational heat-related illnesses and exposure to summer outdoor temperatures. Methods: We modeled 259 heat-related illnesses compensated by the Workers' Compensation Board of Quebec between May and September, from 1998 to 2010, with maximum daily summer outdoor temperatures in 16 health regions of Quebec (Canada) using generalized linear models with negative binomial distributions, and estimated the pooled effect sizes for all regions combined, by sex and age groups, and for different time lags with random-effect models for meta-analyses. Results: The mean daily compensation count was 0.13 for all regions of Quebec combined. The relationship between daily counts of compensations and maximum daily temperatures was log-linear; the pooled incidence rate ratio (IRR) of daily heat-related compensations per 1 °C increase in daily maximum temperatures was 1.419 (95% CI 1.326 to 1.520). Associations were similar for men and women and by age groups. Increases in daily maximum temperatures at lags 1 and 2 and for two and three-day lag averages were also associated with increases in daily counts of compensations (IRRs of 1.206 to 1.471 for every 1 °C increase in temperature). Conclusion: This study is the first to quantify the association between occupational heat-related illnesses and exposure to summer temperatures in Canada. The model (risk function) developed in this study could be useful to improve the assessment of future impacts of predicted summer outdoor temperatures on workers and vulnerable groups, particularly in colder

    Purpose The advent of new technologies and social media offers a host of possibilities for teenagers to consolidate social networks. Unfortunately, new technologies also represent a potential setting for experiences of victimization. Methods The present study explores the prevalence of cyberbullying victimization in a representative sample of 8 194 teenagers in Quebec and the adverse associated consequences. Results Results indicate that 18% of boys and close to 1 out of 4 girls report at least one incident of cyberbullying in the past 12 months. Cyberbullying victimization contributes to the prediction of low self-esteem and psychological distress over and above other experiences of bullying in schools or other settings. Conclusions Cyberbullying appear as one important target for the design of prevention and intervention services designed for youth. PMID:25128859

  4. La gestion des gestionnaires de projets: Le cas de l'industrie aerospatiale au Quebec

    Petit, Marie-Claude

    This research focuses on the management of project managers (PMs) working in high technology organizations. In particular, it examines how these professionals are taken charge of from a human resources management (HRM) standpoint in firms within the aerospace industry in Quebec. The literature in the field of project management generally depicts PMs as entrepreneurs and resource managers, managing human resources (e.g. project team members) among other things. It also defines them as single-handedly responsible for managing their own career, stress and motivation. This profile suggests that once selected and assigned to projects, PMs receive little attention in terms of HRM from the organization. It is hardly conceivable, however, that PMs would move about completely on their own within the organization, let alone that they wouldn't represent any special challenge in terms of HRM, as the ones the literature so clearly underlines for project team members. The review of the literature also reveals that the subject of HRM as applied to PMs is poorly documented empirically, especially on the topic of what particular challenges the project context might bring up for the HRM of PMs. There is also little told about the actors involved in supporting and contributing to meet the challenges that arise out of managing PMs. This study sought to discern those challenges and the means put forth to address them. Also, it wanted to identify the actors of the HRM of PMs, their roles, their skills, and their relationships, among themselves and with the PMs, in order to efficiently take charge of them. This study also wanted to demonstrate the logic that ties the means put forth by the identified actors with the objectives PM-employing organizations want to reach. Finally, the study wanted to identify the impact of the HRM of PMs as it is occurring in organizations. The Quebec aerospace sector was chosen as the field of research primarily because the success of projects in

    The lowbush blueberry (Vaccinium angustifolium Ait.) is an important commercial crop of the Lac-Saint-Jean area (Quebec, Canada). The major blueberry fields are located on sandy soils relatively poor in available mineral nutrients. The nutrients originate from a thin organic layer found on the top of these sandy soils. The leaf mineral contents (N, P, K, Mg, Ca, Mn, Fe, Cu, Zn and B) were measured in five blueberry fields during 1984 and 1985. Soil pH and soil available P, K, and Mg were also assessed. The results show that the leaf mineral contents are generally adequate. However, K and Zn might be occasionally deficient when compared to the actual established standards. The available Mg in soil was significantly correlated with the leaf Mg concentration. The data also suggest that the influence of the pH following the burn pruning seems to influence the nutrition of this species.

    The Weedon mine site was remediated by the Government of Quebec in the summer of 1993. Erosion produced a large quantity of oxydized and acid generating tailings spread over more than 13 hectares of wooded land. Vast areas were exposed to leaching and precipitation of metals and sulphur, contaminating the surface waters. A site clean-up was undertaken and the dispersed tailings were excavated and confined in a capsule using a high-density polyethylene geomembrane cover. An innovative concept was developed to encapsulate the tailings on a sloping terrain, using acid generating wasterock for internal and perimeter containment. The cost of containing and covering the contaminated waste was 240 000 $ CAN/hectare.

    The Quaternary Geologic Map of the Quebec 4? x 6? Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during the past 2+ million years, the period that includes all activities of the human species. These materials are at the surface of the Earth. They make up the 'ground' on which we walk, the 'dirt' in which we dig foundations, and the 'soil' in which we grow crops. Most of our human activity is related in one way or another to these surface materials that are referred to collectively by many geologists as regolith, the mantle of fragmental and generally unconsolidated material that overlies the bedrock foundation of the continent. The maps were compiled at 1:1,000,000 scale.

    Education is a provincial responsibility in Canada, but there is a sharing of expenditure and strong support of public education, health and other welfare programs between the provinces and the federal government. Although the federal policy of multiculturalism has been aimed at making Canada a `just' society, the implementation of this policy in education in English-speaking Canada has been far from satisfactory, and there is great variation among the provinces in educational programs. In Quebec, the federal policy of multiculturalism is ideologically opposed to the vision of French-Québécois nationalism. While the federal policy of intercultural education has made some attempts to integrate immigrant populations, the focus remains on linguistic programs. In facing the dramatic changes driven by internationalization and a globalized economy, Canadians must respond - so the conclusion of the present study - to the urgent need to redefine the meaning of multiculturalism with radical educational programs.

Site Description - The ground is gently rolling with a weak slope (<5%). In mesic areas (designated as well to moderately well drained areas, according to the Canadian System of Soil Classification (Agriculture Canada Expert Committee on Soil Survey, 1983)), the soil is a ferro-humic to humic podzol covered by an organic layer having an average depth of 26 cm (Fig. 1). In humid areas, the soil is organic (imperfectly to poorly drained) with an average organic layer of 125 cm. Mesic areas accounted for approximately 75% of the total surface area of the footprint and humid areas accounted for 25%. Full-time continuous measurements eneded in 2011. Intermittent measurements are on-going as resources permit.

    The increasing availability of direct to consumer genetic tests, particularly over the Internet, raises a number of difficult to answer legal questions for health care professionals. While lawmakers have enacted an exhaustive legislative scheme aimed at ensuring the efficiency and universality of publicly funded health care, genetic services sold outside the public system create have created a new challenge for the public system. An analysis of both Quebec and Federal legislation highlights the gaps in the current legal framework with regards to freely available genetic services. The varied impact of failing to address direct to consumer sales of genetic testing services is identified, including implications for consumer protection, control and regulation of testing, and their integration into the public health care system. According to this analysis, resolving these problems, in light of the need for consumer protection, and controlling the use of genetic tests is an essential first step towards the integration of genetic services into the public health care system.

    Health-care providers play a major role in providing good quality care and in preventing psychological distress among mothers living with HIV (MLHIV). The objectives of this study are to explore the impact of health-care services and satisfaction with care providers on psychological distress in MLHIV. One hundred MLHIV were recruited from community and clinical settings in the province of Quebec (Canada). Prevalence estimation of clinical psychological distress and univariate and multivariable logistic regression models were performed to predict clinical psychological distress. Forty-five percent of the participants reported clinical psychological distress. In the multivariable regression, the following variables were significantly associated with psychological distress while controlling for sociodemographic variables: resilience, quality of communication with the care providers, resources, and HIV disclosure concerns. The multivariate results support the key role of personal, structural, and medical resources in understanding psychological distress among MLHIV. Interventions that can support the psychological health of MLHIV are discussed. PMID:25587793

    When decision-makers are engaged in a polarized discourse and leaving aside evidence-based recommendations, is there a role for researchers in the dissemination of this scientific evidence to the general public as a means to counterbalance the debate? In response to the controversial Bill 10 in Quebec, we developed and posted a knowledge transfer video on YouTube to help stimulate critical public debate. This article explains our approach and methodology, and the impact of the video, which, in the space of two weeks, had more than 9,500 views, demonstrating the pertinence of such initiatives.

    Beginning in 2006, point infection control operations and aerial distribution of oral rabies vaccines along the US border were performed in Quebec, Canada, to control the potential spread of raccoon rabies. A benefit-cost analysis assessed the economic efficiency of this rabies control programme into the future. In this study, a mathematical simulation model was used to determine the potential spread of raccoon rabies from the 2006 index case, and incidence rates of human post-exposure prophylaxis (PEP), animal testing and human exposure investigations were calculated. Benefits were calculated as the potential savings from reduced numbers of human PEP, animal testing and human exposure investigations owing to control, which ranged from $47 million to $53 million. Programme cost scenarios were based on projections of total expenditures, which ranged from $33 million to $49 million. Economic efficiency was indicated for approximately half of the modelled scenarios, with the greatest benefit-cost ratios resulting from reduced future programme costs. PMID:22709550

    Two pollen diagrams from lakes north of treeline in northwestern Quebec indicate that Picea never extended north of its present-day limit during the past 6000 yr BP. Alnus crispa was slightly more abundant around 5000 BP, but there are few major changes in the vegetation of the region during the Holocene. A third site in the tundra along Hudson Bay has a slightly longer sequence (7000 yr BP) which indicates more open conditions in the early and recent part of the record. Picea may have been more abundant locally around 3000 BP. Few major changes in these diagrams can be unequivocally attributed to local changes in plant abundance; changes in tree and shrub pollen abundance parallel those seen south of treeline.

    Respiratory effects of ozone in the workplace have not been extensively studied. Our aim was to explore the relationship between daily average ozone levels and compensated acute respiratory problems among workers in Quebec between 2003 and 2010 using a time-stratified case-crossover design. Health data came from the Workers’ Compensation Board. Daily concentrations of ozone were estimated using a spatiotemporal model. Conditional logistic regressions, with and without adjustment for temperature, were used to estimate odds ratios (ORs, per 1 ppb increase of ozone), and lag effects were assessed. Relationships with respiratory compensations in all industrial sectors were essentially null. Positive non-statistically significant associations were observed for outdoor sectors, and decreased after controlling for temperature (ORs of 0.98; 1.01 and 1.05 at Lags 0, 1 and 2 respectively). Considering the predicted increase of air pollutant concentrations in the context of climate change, closer investigation should be carried out on outdoor workers. PMID:25736778

    U-Pb zircon ages of samples of anorthosite, pyroxene monzodiorite (jotunite), and pyroxene quartz monzonite (quartz mangerite) of the Morin anorthosite complex, Grenville Province, Quebec, are 1155 {plus minus} 3, 1146 {plus minus} 4 and 1135 {plus minus} 3 Ma, respectively. These dates are very similar to available dates for equivalent units of the Lac St-Jean and Adirondack anorthosite suite occurrences and slightly predate estimates of 1075-1100 Ma for peak metamorphic conditions during the Grenville orogeny in this region. {sup 87}Sr/{sup 86}Sr initial ratios of 0.7048-0.7051 for the three Morin units sampled permit a comagmatic origin if the different emplacement or cooling times can be reconciled. The mangerite sampled cannot have been formed by fusion of the upper crust, but may have been derived from a relatively juvenile crust at depth. All three units have interacted with continental crust, given the likely depleted nature of the mantle in this region.

    This article aims to present the beneficial effects associated with the local implementation of an integrated network in palliative care, as perceived by diverse constituency groups. A case study was conducted in the province of Quebec, Canada, using individual (n=16) and group (n=16) interviews, with a total of 106 participants (i.e. managers and formal and informal caregivers). From a content analysis, two categories of beneficial effects emerged: those associated with professional practice and those with patient services. The most important effects of this organisational initiative were found to be the recognition of the palliative care domain necessitating specialized competencies, an improved interdisciplinary collaboration, and more efficient circulation of information between care settings, as well as improved accessibility, continuity and quality of care and services to patients at the end of life.

    The Beekmantown Group in the Quebec Lowlands was deposited as part of an extensive Early Ordovician coastal and shallow marine complex on the eastern margin of the North American craton. The Beekmantown is stratigraphically equivalent to the Beekmantown, Knox, Arbuckle, and Ellenburger rocks of the United States, and is subdivided into two formations: the sandstone-rich Theresa Formation and the overlying dolomite-rich Beauharnois. Dolomites of the Beekmantown provide an important exploration target in both the autochthon and the overlying thrust sheets of the Canadian and U.S. Appalachians. The reservoir potential of the autochthonous Beekmantown Group in the Quebec Lowlands can be determined from seismic data, well logs, cuttings, and petrographic analyses of depositional and diagenetic textures. Deposition of the Beekmantown occurred alongson the western passive margin of the Iapetus Ocean. By the Late Ordovician, the passive margin had been transformed into a foreland basin. Faulting locally positioned Upper Ordovician Utica source rocks against the Beekmantown and contributed to forming hydrocarbon reservoirs. The largest Beekmantown reservoir found to date is the St. Flavien field, with 7.75 bcf of original gas (methane) in place in fractured and possibly karst-influenced allochthonous dolomites within a thrust-fault anticline. Seven major depositional units can be distinguished in cuttings and correlated with wireline logs. Dolomites in the Beekmantown contain vuggy, moldic, intercrystalline, and fracture porosity. Early porosity formed at the top of the major depositional units in peritidal dolomites; however, much of this porosity was later filled by late-stage calcite cement after hydrocarbon migration. Thus, a key to finding gas reservoirs in the autochthonous Beekmantown is to define Ordovician poleostructures in which early and continuous entrapment of hydrocarbons prevented later cementation.

    Understory species play a significant role in forest ecosystem dynamics. As such, species of the Ericaceae family have a major effect on the regeneration of tree species in boreal ecosystems. It is thus imperative to understand the ecological gradients controlling their distribution and abundance, so that their impacts can be taken into account in sustainable forest management. Using innovative analytical techniques from landscape ecology, we aimed to position, along ecological gradients, four Ericaceae found in the boreal forest of Quebec (Canada) (Rhododendron groenlandicum, Kalmia angustifolia, Chamaedaphne calyculata, and Vaccinium spp), to regionalize these species into landscape units relevant to forest management, and to estimate the relative importance of several ecological drivers (climate, disturbances, stand attributes, and physical environment) that control the species distribution and abundance. We conducted our study in boreal Quebec, over a study area covering 535,355 km(2). We used data from 15,339 ecological survey plots and forest maps to characterize 1422 ecological districts covering the study region. We evaluated the relative proportion of each ericaceous species and explanatory variables at the district level. Vegetation and explanatory variables matrices were used to conduct redundancy, cluster, and variation partitioning analyses. We observed that ericaceous species are mainly distributed in the western part of the study area and each species has a distinct latitudinal and longitudinal gradient distribution. On the basis of these gradients, we delimited 10 homogeneous landscape units distinct in terms of ericaceous species abundance and environmental drivers. The distribution of the ericaceous species along ecological gradients is closely related to the overlaps between the four sets of explanatory variables considered. We conclude that the studied Ericaceae occupy specific positions along ecological gradients and possess a specific

    Background Acute care surgery (ACS) comprises trauma and emergency surgery. The purpose of this new specialty is to involve trauma and nontrauma surgeons in the care of acutely ill patients with a surgical pathology. In Quebec, few acute care surgery services (ACSS) exist, and the concept is still poorly understood by most general surgeons. This survey was meant to determine the opinions and interest of Quebec general surgeons in this new model. Methods We created a bilingual electronic survey using a Web interface and sent it by email to all surgeons registered with the Association québécoise de chirurgie. A reminder was sent 2 weeks later to boost response rates. Results The response rate was 36.9%. Most respondents had academic practices, and 16% worked in level 1 trauma centres. Most respondents had a high operative case load, and 66% performed at least 10 urgent general surgical cases per month. Although most (88%) thought that ACS was an interesting field, only 45% were interested in participating in an ACSS. Respondents who deemed this concept least applicable to their practices were more likely to be working in nonacademic centres. Conclusion Despite a strong interest in emergency general surgery, few surgeons were interested in participating in an ACSS. This finding may be explained by lack of comprehension of this new model and by comfort with traditional practice. We aim to change this paradigm by demonstrating the feasibility and benefits of the new ACSS at our centre in a follow-up study. PMID:23883506

    Background Alcohol and drug use is a serious health problem for many indigenous populations across Canada, including Inuit. The literature on substance use in these populations is too sparse to devise public health interventions. Objective The present article portrays alcohol and drug use among Inuit living in Nunavik (Northern Quebec) between the 1990s and 2000s, and identifies socio-demographic characteristics related to substance use. Design The Santé Québec Health Survey (1992) and the Nunavik Inuit Health Survey Qanuippitaa (2004) served as databases for this empirical work. Statistical comparisons were made of substance use variables in the 2 samples. Proportions were compared by chi-square tests (p≤0.05) with benchmarking of statistics for all of Quebec and, when available, all of Canada. Results Alcohol and drug use among Inuit increased significantly between 1992 and 2004, particularly among young adults. Alcohol users consumed significantly more alcohol per drinking episode than other Canadians in both time periods. Considerable cannabis use was widespread. In 2004, no significant differences in frequencies of heavy drinking episodes were observed by gender, with 60% of drug users consuming alcohol on a regular basis. Conclusions As in other populations from North America, this study profiles the increase in substance use among Inuit from Nunavik in the first part of the last 20 years. We observed distinct substance use patterns among them in comparison to other Canadians. Such findings, if replicated in the coming years, emphasize the need for major, culturally-relevant public health interventions in this population. PMID:26689846

    Waste stabilisation ponds (WSPs) are highly enriched environments that may emit large quantities of greenhouse gases (GHG), including CO2, CH4 and N2O. However, few studies provide detailed reports on these emissions. In the present study, we investigated GHG emissions from WSPs in Western Australia and Quebec, Canada, and compared emissions to WSPs from other climatic regions and to other types of aquatic ecosystems. Surface water GHG concentrations were related to phytoplankton biomass and nutrients. The CO2 was either emitted or absorbed by WSPs, largely as a function of phytoplankton dynamics and strong stratification in these shallow systems, whereas efflux of CH4 and N2O to the atmosphere was always observed albeit with highly variable emission rates, dependent on treatment phase and time of the day. The total global warming potential index (GWP index, calculated as CO2 equivalent) of emitted GHG from WSPs in Western Australia averaged 12.8 mmol m(-2) d(-1) (median), with CO2, CH4 and N2O respectively contributing 0%, 96.7% and 3.3% of the total emissions, while in Quebec WSPs this index was 194 mmol m(-2) d(-1), with a relative contribution of 93.8, 3.0 and 3.2% respectively. The CO2 fluxes from WSPs were of the same order of magnitude as those reported in hydroelectric reservoirs and constructed wetlands in tropical climates, whereas CH4 fluxes were considerably higher compared to other aquatic ecosystems. N2O fluxes were in the same range of values reported for WSPs in subtropical climate. PMID:27258617

    The large 1950s fires that burned > 5,500 km{sup 2} of land across a south-to-north climatic gradient in northern Quebec provide an opportunity to evaluate the role of fire in forest-tundra development on a demographic basis. The tree population density before and {approx} 30 yr after fire was estimated by censusing trees in plots of 400 m{sup 2} located in upland and lowland within four representative ecoregions of northern Quebec. The analysis of tree recruitment before and after fire, in 410 randomly selected sites along a transect crossing the upper boreal forest and forest-tundra zones, indicated that wildfires induced substantial depletion of tree populations. Taken as a whole, fires have significantly reduced the density of black spruce populations in forest-tundra uplands, but not in the lowlands. Sustained reduction of tree population density after several destructive fires appears as one of the main deforestation processed in the subarctic zone. This leads to the patchy distribution of forest stands and scattered tree populations typical of the forest-tundra biome. Comparisons with paleoecological data suggest that the impact of the 1950s fires contributed to the expansion of the forest tundra into the upper boreal forest. The ecological impact of these fires was probably similar to those fires responsible for development of the forest tundra during the Holocene. It is suggested that the fire-climate interaction should be considered in order to predict the ecological impact of warming climate on high-latitude forest ecosystems.

    Postoperative cognitive disorders are common in elderly patients. Pre-existing cognitive impairment including mild cognitive impairment may be an important risk factor for developing postoperative cognitive dysfunction and may not be detected in a standard preoperative interview, yet is not routinely sought. Our primary aim was to estimate the prevalence of mild cognitive impairment among elderly patients presenting to our hospital for elective surgery using a simple established screening tool: the Montreal Cognitive Assessment test. Secondarily, we wished to determine the proportion of patients with mild cognitive impairment who presented with this information available, the effect of increasing age on the prevalence of mild cognitive impairment and whether the timing and location of testing influenced results. We used the Montreal Cognitive Assessment test to screen preoperative patients aged 65 years and over. Our results suggested a potential prevalence of mild cognitive impairment of 56%, with prevalence increasing with age. No patients in the sample had a recorded diagnosis of mild cognitive impairment. Testing in either the preadmission clinic or on admission on the day of surgery yielded similar results. We found the Montreal Cognitive Assessment test to be a simple screening tool that was easily administered during the pre-admission visit. PMID:27608340

    2000-01-01

    The creation of imaginary families among street youth gives the peer group an identity prop that enables a young person living on the street to escape from his or her real family, thus reinforcing the imaginary dimension surrounding the myth of natural autonomy. While the group may gain a real sense of protection that is necessary in adolescence, the familialist projection that these young people unconsciously call into play constitutes what the founder of socio-psychoanalysis, Gérard Mendel, calls "psycho-familialist regression". Society is not a family, and familialist projections may block social relations with any adults who are identified with parental authority that may be potentially threatening for the "family of street youth". For that reason, in 1998, a form of collective mediation was tested in Montreal as part of a pilot project to develop young street people's social autonomy through on-going dialogue between them, elected municipal officials and youth workers. Relying on applied research from socio-psychoanalysis, this pilot project made it possible to alleviate familialist projections and offer street youth other alternatives in terms of self-image.

    Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences. This would mean that the climate system is close to entering if not already within the zone of “dangerous anthropogenic interference” (DAI). Scientific and policy literature refers to the need for “early,” “urgent,” “rapid,” and “fast-action” mitigation to help avoid DAI and abrupt climate changes. We define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades. We discuss strategies for short-lived non-CO2 GHGs and particles, where existing agreements can be used to accomplish mitigation objectives. Policy makers can amend the Montreal Protocol to phase down the production and consumption of hydrofluorocarbons (HFCs) with high global warming potential. Other fast-action strategies can reduce emissions of black carbon particles and precursor gases that lead to ozone formation in the lower atmosphere, and increase biosequestration, including through biochar. These and other fast-action strategies may reduce the risk of abrupt climate change in the next few decades by complementing cuts in CO2 emissions. PMID:19822751

    Objective We sought to compare age-related performance on the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) across the adult lifespan in an asymptomatic, presumably normal, sample. Background The MMSE is the most commonly used brief cognitive screening test; however, the MoCA may be better at detecting early cognitive dysfunction. Methods We gave the MMSE and MoCA to 254 community-dwelling participants ranging in age from 20 to 89, stratified by decade and we compared their scores using the Wilcoxon signed rank test. Results For the total sample, the MMSE and MoCA differed significantly in total scores as well as in visuospatial, language, and memory domains (for all of these scores, P <0.001). Mean MMSE scores declined only modestly across the decades; mean MoCA scores declined more dramatically. There were no consistent domain differences between the MMSE and MoCA during the 3rd and 4th decades; however, significant differences in memory (P <0.05) and language (P <0.001) emerged in the 5th through 9th decades. Conclusions We conclude that the MoCA may be a better detector of age-related decrements in cognitive performance than the MMSE, as shown in this community-dwelling adult population. PMID:23538566

    The validity of the Montreal Cognitive Assessment (MoCA) as a screen for mild cognitive impairment (MCI) and dementia was evaluated in African Americans attending an urban outpatient memory disorders clinic. Eighty one patients ≥50 years old were administered the MoCA and neuropsychological tests. Clinicians, blinded to the MoCA scores, reviewed the neuropsychological findings and reports of instrumental activities of daily living and they assigned a diagnosis of normal cognition (NC; N = 16), MCI (N = 38), or dementia (N = 27). The MoCA scores of the 3 groups were significantly different (NC > MCI > dementia). Using cutoff scores of ≤24 points for MCI and ≤22 points for dementia, the MoCA had .95 sensitivity and .63 specificity for MCI and .96 sensitivity and .88 specificity for dementia. The MoCA is a valid and cost-effective screen for cognitive impairment in African Americans but with a higher likelihood of falsely classifying persons with NC as having MCI. PMID:24614202

    The short life span of many street trees in the Montreal downtown area may be due in part to higher than standard concentrations of trace metals in the tree pit soils. The effects of land use, soil organic matter, and time since tree planting in a given tree pit (soil age) were studied with respect to the total concentration of trace metals (Cr, Ni, Cu, Zn, Cd, and Pb) in soil collected from tree pits on commercial and residential streets. Contingency table analysis and multiple linear regression were applied to study how these variables were related to the total concentrations of trace metals in soil. Other variables, such as pH, street width, distance of the tree pit from the curb, and tree pit volume, were also used as input to statistical analysis to increase the analysis' explanatory power. Significantly higher concentrations of Cu, Cd, Zn, and Pb were observed in soils from commercial streets, possibly as a result of heavier traffic as compared with residential streets. Soil organic matter was positively correlated with the concentrations of Cu and Pb, probably due to the ability of organic matter to retain these trace metals. Nickel, Cu, Zn, Cd, and Pb were positively correlated with the soil age presumably because trace metals accumulate in the tree pit soil over time. This knowledge can be helpful in providing soil quality standards aimed at improving the longevity of downtown street trees. PMID:24216430

    OBJECTIVE: To validate an adaptation of a short questionnaire measuring behaviour related to selecting low fat diets. The questionnaire was adapted for telephone use in a low income, low education population. DESIGN: The factorial structure of the 38 item adaptation was studied in a population based random sample of 1432 adults. Seven day test-retest reliability was measured in a convenience sample of 93 adults, and criterion related validity in measuring fat was assessed against a dietitian administered diet history in another convenience sample of 81 adults. SETTING: Adults aged 18-65 years living in low income, inner city neighbourhoods in Montreal, Canada. RESULTS: Principal components analysis identified five food factors: avoid fat, junk food, high fat traditional foods, low fat substitutes for high fat foods, and modification of meat to reduce fat. Two factors were similar to those of the original version. Internal consistency of the subscales ranged from 0.49-0.72. Test-retest reliability ranged from 0.72-0.90. Validation of the subscales against usual dietary intake indicated that the "junk food" factor, arising from questions added to the original questionnaire to reflect local dietary habits, was most closely related to fat intake (r = 0.48; p < 0.001). CONCLUSION: This telephone adaptation provides an inexpensive and valid method of measuring fat intake. However, these results suggest that adaptations of existing dietary instruments should be validated in the populations for which they are intended before they are used. PMID:9229065

    Despite music's universality, people perceive and interpret music according to their cultural background. The existing music perception batteries, however, do not take into account possible cultural differences. We adapted the Montreal Battery of Evaluation of Amusias (MBEA) into the requirements of Eastern (Greek) music, where rhythm and melody scales are different from the ones used in Western music. We obtained norms for both the original version of MBEA and its Greek adaptation from the same Greek participants because they are exposed to both genres (traditional and Eastern). Results indicate that some parts of the original MBEA such as the meter test would not be suitable for evaluating the musical abilities of populations with a different musical tradition. Instead, our version of the MBEA, the Greek Battery of Evaluation of Amusia (GBEA) should be preferred in assessing music perception in cultures or individuals influenced by Eastern or both traditions. We also report the results of a congenitally amusic individual (B.Z.) evaluated with both batteries showing that GBEA is a more sensitive tool to evaluate her impairment in music perception.

    The author describes the history of the Fonds de la recherche en santé du Québec, from after World War II to the present day. The Conseil de la recherche médicale du Québec (Quebec Medical Research Council) was created in 1964 to bring Quebec up to speed in biomedical research through programs that complemented those of the Medical Research Council of Canada. The council progressively evolved, becoming the Conseil de la recherche en santé du Québec (Quebec Health Research Council) in 1974 and the Fonds de la recherche en santé du Québec (FRSQ) in 1982. The FRSQ covers all aspects of medical research, in its broadest sense. Quebec's progress in biomedical research has been spectacular and has had direct and considerable influence on the quality of medical education and patient care. From 1982 to 1996, various Quebec governments have devoted more than +500 million to the FRSQ, a testimony to their comprehension of the importance of this area and to their farsightedness. The FRSQ and its predecessor organizations have been a major force in improving and maintaining the quality of medical teaching and care in Quebec during the last three decades. PMID:8823209

    This article reports the results of a study on the outcomes of the Canada-Quebec Infrastructure Works 2000 Program (CQIWP), an infrastructure grant program to Quebec municipalities. The focus of this study is on the effects of the CQIWP on municipal investment and physical conditions of drinking water systems and, as such, it goes beyond the usual emphasis on the fiscal consequences of intergovernmental grants. The study results show that the CQIWP was an efficient tool to induce municipalities to increase investment and to reduce the number of aqueduct breakdowns. In light of these findings, this study suggests that upper levels of governments can rely on infrastructure grants to fill the gap in municipal investment and, therefore, to improve the availability and quality of municipal infrastructure.

    Although raptors have been protected for decades in Quebec they are still regular victims of poaching. The objective of this study was to characterize cases of raptor shootings in Quebec over the last 2 decades. We reviewed clinical files, radiographs, and pathology reports on 4805 free-flying birds of prey admitted to the Faculté de médecine vétérinaire between 1986 and 2007. Evidence of gunshots was detected in 6.4% of the birds. Large species, such as ospreys, turkey vultures, snowy owls, and bald eagles represented the most frequently targeted species. The percentage of shot birds has decreased from 13.4% during 1991 to 1992 to 2.2% in 2006 to 2007. Potential reasons for this trend include a decrease in the presence of firearms in raptor habitats and changes in human attitude towards raptorial birds. PMID:20357944

    The Rey-Osterrieth (ROCF) and Taylor (TCF) complex figure tests are widely used to assess visuospatial and constructional abilities as well as visual/non-verbal memory. Normative data adjusted to the cultural and linguistic reality of older Quebec-French individuals is still nonexistent for these tests. In this article, we report the results of two studies that aimed to establish normative data for Quebec-French people (aged at least 50 years) for the copy, immediate recall, and delayed recall trials of the ROCF (Study 1) and the TCF (Study 2). For both studies, the impact of age, education, and sex on test performance was examined. Moreover, the impact of copy time on test performance, the impact of copy score on immediate and delayed recall score, and the impact of immediate recall score on delayed recall performance were examined. Based on regression models, equations to calculate Z scores for copy and recall scores are provided for both tests. PMID:25472685

    This paper presents a public health narrative on Quebec's new climatic conditions and human health, and describes the transdisciplinary nature of the climate change adaptation research currently being adopted in Quebec, characterized by the three phases of problem identification, problem investigation, and problem transformation. A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human-environment interactions (for example, climate change), for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change) in multi-actors contexts has progressively been established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a "public health narrative" presented in three phases: (1) problem identification (1998-2002) beginning in northern Quebec; (2) problem investigation (2002-2006) in which

    Musculoskeletal disorders are among the leading causes of work-related physical disability in the province of Quebec in Canada. The authors conducted a focus group study with physiotherapists and physical rehabilitation therapists working with patients whose treatments are compensated by the Quebec Workers' Compensation Board with the goal of exploring quality of care and ethical issues. Three main themes were identified: (1) systemic factors, (2) complexity in treatment decisions and (3) inequality of care. Although physiotherapy professionals strive to give these patients the best possible care, patients might not always be provided with optimal or equal treatment. When compared with other patients, there appear to be differences with respect to access to care and types of services offered to injured workers, raising equity concerns. Factors that shape and constrain quality of physiotherapy services for injured workers need to be addressed to improve care for these patients. PMID:25947032

    Studies worldwide point toward increased risk of mental health issues among immigrants. Immigrants’ ability to integrate the cultural identity of their new country has been found to be a key factor in their psychological well-being. Even though researchers agree on the crucial role of identity integration in immigrants’ well-being, the current literature has two main limitations: (1) researchers do not agree on the importance that should be allocated to each of the cultural identities, and (2) research has focused on bicultural individuals as opposed to multicultural individuals. The present paper proposes to study Canadians immigrants living in the province of Quebec who, because of the political and linguistic situation of the province, face the challenge of integrating two new cultural identities (Quebecer and Canadian) to their original one. Specifically, cluster analysis was used to observe identity profiles that naturally emerge among 120 Canadian immigrants from the province of Quebec. Identity profiles were then compared on various indices of well-being to identify the optimal identity structure. In total, four identity profiles emerged, differing in their levels of identity coherence (i.e., similar levels of identification with each group) and identification to either the original group or the Quebecers. ANOVA results confirmed that identity profiles differed in their average level of well-being. First, immigrants with coherent profiles displayed higher levels of well-being. Second, among incoherent profiles, the profile where identification to the original group is the highest showed the greatest well-being. Implications suggest that in order to maximize immigrants’ well-being, psychologists should focus on the coherence between cultural groups as well as identification to the original group.

    Beta-thalassemia minor occurs at 5% frequency (on average) in populations migrant (since 1945) from Mediterranean countries to the province of Quebec. Individuals of Southeast Asian/Chinese and Asian Indian origin now living in the province also carry beta-thalassemia genes at similar frequencies. We characterized beta-thalassemia genes on 68 chromosomes (19 patients and 30 carriers identified by screening) to describe heterogeneity of beta-thalassemia alleles and to evaluate desirability of DNA tests in carrier screening. Thirteen different mutations account for 74% of the 68 beta-thalassemia chromosomes: seven occur on Mediterranean chromosomes (IVS I,nt110, Non 39, IVS I,nt6, IVS I,nt1G----A, IVS II,nt1, Fr8, IVS II,nt745) another three on SE Asian chromosomes (Fr 41-42, IVS II,nt654, HbE) and yet another three on Asian Indian chromosomes (IVS I,nt5, 619 bp del, IVS I,nt1G----T). Twenty-six percent (18/68) of the chromosomes carried none of 17 alleles accounting for 92-96% of beta-thalassemia molecular pathology in reference populations. The Italian beta-thalassemia chromosomes in the Quebec sample least resembled those in the corresponding source population. Until the spectrum of mutations in Quebec populations is fully defined, phenotype assay remains the most reliable and efficient method for beta-thalassemia carrier screening. PMID:1782730

    In adopting a whole-of-society (WoS) approach that engages multiple stakeholders in public health policies across contexts, the authors propose that effective governance presents a challenge. The purpose of this paper is to highlight a case for how polycentric governance underlying the WoS approach is already functioning, while outlining an agenda to enable adaptive learning for improving such governance processes. Drawing upon a case study from Quebec, Canada, we employ empirically developed concepts from extensive, decades-long work of the 2009 Nobel laureate Elinor Ostrom in the governance of policy in nonhealth domains to analyze early efforts at polycentric governance in policies around overnutrition, highlighting interactions between international, domestic, state and nonstate actors and processes. Using information from primary and secondary sources, we analyze the emergence of the broader policy context of Quebec's public health system in the 20th century. We present a microsituational analysis of the WoS approach for Quebec's 21st century policies on healthy lifestyles, emphasizing the role of governance at the community level. We argue for rethinking prescriptive policy analysis of the 20th century, proposing an agenda for diagnostic policy analysis, which explicates the multiple sets of actors and interacting variables shaping polycentric governance for operationalizing the WoS approach to policymaking in specific contexts.

    The largest two earthquakes in eastern North America (ENA) in the last 50 years are the 2011 Mineral, Virginia and the 1988 Saguenay, Quebec earthquakes, both of moment magnitude (M) 5.8. Both events were relatively well-recorded at regional distances (especially the Virginia earthquake) but have a disappointing lack of instrumental records at distances within 50 km, confounding interpretation of expected near-source motions for moderate-to-large ENA events. At regional distances (200 to 500 km), over frequencies from 0.5 to 10 Hz, the instrumentally-recorded motions from the Virginia and Quebec earthquakes show similar amplitudes and attenuation trends; in both cases the motions agree reasonably well with the trend lines suggested by recent ground-motion prediction equations (GMPEs) such as those of Atkinson and Boore (2011) and Pezeshk et al. (2011). At distances <200 km, limited recorded data suggest that the Virginia event does not have high-frequency motions (5 to 10 Hz) as strong as those seen in the Saguenay earthquake, while low-frequency motions (0.5 to 1 Hz) appear to be larger for the Virginia event than for Saguenay. We can augment our understanding of the relative differences in ground motions and attenuation using intensity data; intensity data have the advantage of being available at close distances where instrumental records are sparse. Intensities for the Virginia event were approximately 1 unit lower than those for Saguenay at close distances (<40 km), but attenuated more slowly with distance. Attenuation differences might be partly due to the different focal depths of the events (6 km for Virginia, 28 km for Saguenay), which may have resulted in Moho-bounce effects being seen in a different distance range. Both events had a mean radius for intensity 3 of about 600 km. The observed mean intensity of 3 at 600 km is in agreement with the intensity GMPE of Atkinson and Wald (2007); at close distances, the Virginia intensities are lower than predicted

    Increasing albedo is an effective strategy to mitigate urban air temperature in different climates. Using reflective urban surfaces decreases the air temperature, which potentially reduces the rate of generation of smog. However, for implementing the albedo enhancement, complicated interactions between air, moisture, aerosols, and other gaseous contaminant in the atmosphere should be considered. We used WRF-CHEM to investigate the effect of increasing albedo in Montreal, Canada, during a heat wave period (July 10th through July 12th, 2005) on air quality and urban climate. The reflectivity of roofs, walls, and roads are increased from 0.2 to 0.65, 0.6, and 0.45, respectively. Air temperature at 2-m elevation is decreased during all hours in the simulation period and the maximum reduction is about 1 °C on each day (Tmax is reduced by about 0.7 °C) The concentration of two regulated pollutants -ozone (O3) and fine particulate matters (PM2.5) - is calculated at a height of 5-m above the ground. The maximum decrease in 8-h averaged ozone concentration is about 3% (∼0.2 ppbv). 24-h averaged PM2.5 concentration decreases by 1.8 μg/m3. This relatively small change in concentration of pollutants is related to the decrease in planetary boundary layer height caused by increasing the albedo. Additionally, the combined effect of decreased solar heat gain by building surfaces and decreased air temperature reduces the energy consumption of HVAC systems by 2% (∼0.1 W/m2), which exacerbates the positive effect of the albedo enhancement on the air quality.

    Satellite remote sensing offers the opportunity to determine the spatial distribution of aerosol properties and could fill the gap of ground-level observations. Various algorithms have recently been developed in order to retrieve the aerosol optical depth (AOD) at continental scales. However, they are, to some extent, subject to coarse spatial resolutions which are not appropriate for intraurban scales as usually needed in health studies. This paper presents an improved AOD retrieval algorithm for satellite instrument MODIS at 1-km resolution for intraurban scales. The MODIS-retrieved AODs are used to derive the ground-level PM2.5 concentrations using the aerosol vertical profiles and local scale factors obtained from the GEOS-Chem model simulation. The developed method has been applied to retrieve the AODs and to evaluate the ground-level PM2.5 over the city of Montreal, Canada for 2009 on daily, monthly and annual scales. The daily and monthly results are compared with the monitoring values with correlations R(2) ranging from 0.86 to 0.93. Especially, the annual mean PM2.5 concentrations are in good agreement with the measurement values at all monitoring stations (r=0.96, slope=1.0132 ± 0.0025, intercept=0.5739 ± 0.0013). This illustrates that the developed AOD retrieval algorithm can be used to retrieve AODs at a higher spatial resolution than previous studies to further derive the regional full coverage PM2.5 results at finer spatial and temporal scales. The study results are useful in health risk assessment across this region. PMID:26473708

    Cyclists may experience increased exposure to traffic-related air pollution owing to increased minute ventilation and close proximity to vehicle emissions. The aims of this study were to characterize personal exposures to air pollution among urban cyclists and to identify potential determinants of exposure including the type of cycling lane (separated vs on-road), traffic counts, and meteorological factors. In total, personal air pollution exposure data were collected over 64 cycling routes during morning and evening commutes in Montreal, Canada, over 32 days during the summer of 2011. Measured pollutants included ultrafine particles (UFPs), fine particles (PM(2.5)), black carbon (BC), and carbon monoxide (CO). Counts of diesel vehicles were important predictors of personal exposures to BC, with each 10 vehicle/h increase associated with a 15.0% (95% confidence interval (CI): 5.7%, 24.0%) increase in exposure. Use of separated cycling lanes had less impact on personal exposures with a 12% (95% CI: -43%, 14%) decrease observed for BC and smaller decreases observed for UFPs (mean: -1.3%, 95% CI: -20%, 17%) and CO (mean: -5.6%, 95% CI: -17%, 4%) after adjusting for meteorological factors and traffic counts. On average, PM(2.5) exposure increased 7.8% (95% CI: -17%, 35%) with separate cycling lane use, but this estimate was imprecise and not statistically significant. In general, our findings suggest that diesel vehicle traffic is an important contributor to personal BC exposures and that separate cycling lanes may have a modest impact on personal exposure to some air pollutants. Further evaluation is required, however, as the impact of separate cycling lanes and/or traffic counts on personal exposures may vary between regions. PMID:22910003

    ABSTRACT Background: The Montreal Cognitive Assessment (MoCA) is used for screening mild cognitive impairment (MCI), and the Beijing version (MoCA-BJ) is widely used in China. We aimed to develop a computerized tool for MoCA-BJ (MoCA-CC). Methods: MoCA-CC used person-machine interaction instead of patient-to-physician interaction; other aspects such as the scoring system did not differ from the original test. MoCA-CC, MoCA-BJ and routine neuropsychological tests were administered to 181 elderly participants (MCI = 96, normal controls [NC] = 85). Results: A total of 176 (97.24%) participants were evaluated successfully by MoCA-CC. Cronbach's α for MoCA-CC was 0.72. The test-retest reliability (retesting after six weeks) was good (intraclass correlation coefficient = 0.82; P < 0.001). Significant differences were observed in total scores (t = 9.38, P < 0.001) and individual item scores (t = 2.18-8.62, P < 0.05) between the NC and MCI groups, except for the score for "Naming" (t = 0.24, P = 0.81). The MoCA-CC total scores were highly correlated with the MoCA-BJ total scores (r = 0.93, P < 0.001) in the MCI participants. The area under receiver-operator curve for the prediction of MCI was 0.97 (95% confidence interval = 0.95-1.00). At the optimal cut-off score of 25/26, MoCA-CC demonstrated 95.8% sensitivity and 87.1% specificity. Conclusion: The MoCA-CC tool developed here has several advantages over the paper-pencil method and is reliable for screening MCI in elderly Chinese individuals, especially in the primary clinical setting. It needs to be validated in other diverse and larger populations. PMID:25362894

    Background Little is known about the respiratory effects of short-term exposures to petroleum refinery emissions in young children. This study is an extension of an ecologic study that found an increased rate of hospitalizations for respiratory conditions among children living near petroleum refineries in Montreal (Canada). Methods We used a time-stratified case–crossover design to assess the risk of asthma episodes in relation to short-term variations in sulfur dioxide levels among children 2–4 years of age living within 0.5–7.5 km of the refinery stacks. Health data used to measure asthma episodes included emergency department (ED) visits and hospital admissions from 1996 to 2004. We estimated daily levels of SO2 at the residence of children using a) two fixed-site SO2 monitors located near the refineries and b) the AERMOD (American Meteorological Society/Environmental Protection Agency Regulatory Model) atmospheric dispersion model. We used conditional logistic regression to estimate odds ratios associated with an increase in the interquartile range of daily SO2 mean and peak exposures (31.2 ppb for AERMOD peaks). We adjusted for temperature, relative humidity, and regional/urban background air pollutant levels. Results The risks of asthma ED visits and hospitalizations were more pronounced for same-day (lag 0) SO2 peak levels than for mean levels on the same day, or for other lags: the adjusted odds ratios estimated for same-day SO2 peak levels from AERMOD were 1.10 [95% confidence interval (CI), 1.00–1.22] and 1.42 (95% CI, 1.10–1.82), over the interquartile range, for ED visits and hospital admissions, respectively. Conclusions Short-term episodes of increased SO2 exposures from refinery stack emissions were associated with a higher number of asthma episodes in nearby children. PMID:19440507

    Premenstrual disorders (PMD) are characterised by a cluster of somatic and psychological symptoms of varying severity that occur during the luteal phase of the menstrual cycle and resolve during menses (Freeman and Sondheimer, Prim Care Companion J Clin Psychiatry 5:30–39, 2003; Halbreich, Gynecol Endocrinol 19:320–334, 2004). Although PMD have been widely recognised for many decades, their precise cause is still unknown and there are no definitive, universally accepted diagnostic criteria. To consider this issue, an international multidisciplinary group of experts met at a face-to-face consensus meeting to review current definitions and diagnostic criteria for PMD. This was followed by extensive correspondence. The consensus group formally became established as the International Society for Premenstrual Disorders (ISPMD). The inaugural meeting of the ISPMD was held in Montreal in September 2008. The primary aim was to provide a unified approach for the diagnostic criteria of PMD, their quantification and guidelines on clinical trial design. This report summarises their recommendations. It is hoped that the criteria proposed here will inform discussions of the next edition of the World Health Organisation's International Classification of Diseases (ICD-11), and the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-V) criteria that are currently under consideration. It is also hoped that the proposed definitions and guidelines could be used by all clinicians and investigators to provide a consistent approach to the diagnosis and treatment of PMD and to aid scientific and clinical research in this field.

    Increasing albedo is an effective strategy to mitigate urban air temperature in different climates. Using reflective urban surfaces decreases the air temperature, which potentially reduces the rate of generation of smog. However, for implementing the albedo enhancement, complicated interactions between air, moisture, aerosols, and other gaseous contaminant in the atmosphere should be considered. We used WRF-CHEM to investigate the effect of increasing albedo in Montreal, Canada, during a heat wave period (July 10th through July 12th, 2005) on air quality and urban climate. The reflectivity of roofs, walls, and roads are increased from 0.2 to 0.65, 0.6, and 0.45, respectively. Air temperature at 2-m elevation is decreased during all hours in the simulation period and the maximum reduction is about 1 °C on each day (Tmax is reduced by about 0.7 °C) The concentration of two regulated pollutants -ozone (O3) and fine particulate matters (PM2.5) - is calculated at a height of 5-m above the ground. The maximum decrease in 8-h averaged ozone concentration is about 3% (∼0.2 ppbv). 24-h averaged PM2.5 concentration decreases by 1.8 μg/m3. This relatively small change in concentration of pollutants is related to the decrease in planetary boundary layer height caused by increasing the albedo. Additionally, the combined effect of decreased solar heat gain by building surfaces and decreased air temperature reduces the energy consumption of HVAC systems by 2% (∼0.1 W/m2), which exacerbates the positive effect of the albedo enhancement on the air quality.

  14. How health professionals perceive and experience treating people on social assistance: a qualitative study among dentists in Montreal, Canada

    PubMed Central

    2013-01-01

    Background In Canada, the prevalence of oral diseases is very high among people on social assistance. Despite great need for dental treatment, many are reluctant to consult dental professionals, arguing that dentists do not welcome or value poor patients. The objective of this research was thus to better understand how dentists perceived and experienced treating people on social assistance. Methods This descriptive qualitative research was based on in-depth semi-structured interviews with 33 dentists practicing in Montreal, Canada. Generally organized in dentists’ offices, the interviews lasted 60 to 120 minutes; they were digitally recorded and later transcribed verbatim. The interview transcripts were coded with NVivo software, and data was displayed in analytic matrices. Three members of the research team interpreted the data displayed and wrote the results of this study. Results Dentists express high levels of frustration with people on social assistance as a consequence of negative experiences that fall into 3 categories: 1) Organizational issues (people on social assistance ostensibly make the organization of appointments and scheduling difficult); 2) Biomedical issues (dentists feel unable to provide them with adequate treatment and fail to improve their oral health); 3) Financial issues (they are not lucrative patients). To explain their stance, dentists blame people on social assistance for neglecting themselves, and the health care system for not providing adequate coverage and fees. Despite dentists’ willingness to treat all members of society, an accumulation of frustration leads to feelings of powerlessness and discouragement. Conclusions The current situation is unacceptable; we urge public health planners and governmental health agencies to ally themselves with the dental profession in order to implement concrete solutions.

    Vehicle operating speed measured on roadways is a critical component for a host of analysis in the transportation field including transportation safety, traffic flow modeling, roadway geometric design, vehicle emissions modeling, and road user route decisions. The current research effort contributes to the literature on examining vehicle speed on urban roads methodologically and substantively. In terms of methodology, we formulate a new econometric model framework for examining speed profiles. The proposed model is an ordered response formulation of a fractional split model. The ordered nature of the speed variable allows us to propose an ordered variant of the fractional split model in the literature. The proposed formulation allows us to model the proportion of vehicles traveling in each speed interval for the entire segment of roadway. We extend the model to allow the influence of exogenous variables to vary across the population. Further, we develop a panel mixed version of the fractional split model to account for the influence of site-specific unobserved effects. The paper contributes substantively by estimating the proposed model using a unique dataset from Montreal consisting of weekly speed data (collected in hourly intervals) for about 50 local roads and 70 arterial roads. We estimate separate models for local roads and arterial roads. The model estimation exercise considers a whole host of variables including geometric design attributes, roadway attributes, traffic characteristics and environmental factors. The model results highlight the role of various street characteristics including number of lanes, presence of parking, presence of sidewalks, vertical grade, and bicycle route on vehicle speed proportions. The results also highlight the presence of site-specific unobserved effects influencing the speed distribution. The parameters from the modeling exercise are validated using a hold-out sample not considered for model estimation. The results indicate

    Although the relationship between aging and cognitive decline is well established, there is substantial individual variability in the degree of cognitive decline in older adults. The present study investigates whether variability in cognitive performance in community-dwelling older adults is related to the presence of whole brain or tract-specific changes in white matter microstructure. Specifically, we examine whether age-related decline in performance on the Montreal Cognitive Assessment (MoCA), a cognitive screening tool, is mediated by the white matter microstructural decline. We also examine if this relationship is driven by the presence of cardiovascular risk factors or variability in cerebral arterial pulsatility, an index of cardiovascular risk. Sixty-nine participants (aged 43-87) completed behavioral and MRI testing including T1 structural, T2-weighted FLAIR, and diffusion-weighted imaging (DWI) sequences. Measures of white matter microstructure were calculated using diffusion tensor imaging analyses on the DWI sequence. Multiple linear regression revealed that MoCA scores were predicted by radial diffusivity (RaD) of white matter beyond age or other cerebral measures. While increasing age and arterial pulsatility were associated with increasing RaD, these factors did not mediate the relationship between total white matter RaD and MoCA. Further, the relationship between MoCA and RaD was specific to participants who reported at least one cardiovascular risk factor. These findings highlight the importance of cardiovascular risk factors in the presentation of cognitive decline in old age. Further work is needed to establish whether medical or lifestyle management of these risk factors can prevent or reverse cognitive decline in old age. PMID:26511789

    This paper presents a public health narrative on Quebec’s new climatic conditions and human health, and describes the transdisciplinary nature of the climate change adaptation research currently being adopted in Quebec, characterized by the three phases of problem identification, problem investigation, and problem transformation. A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human–environment interactions (for example, climate change), for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change) in multi-actors contexts has progressively been established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a “public health narrative” presented in three phases: (1) problem identification (1998–2002) beginning in northern Quebec; (2) problem investigation (2002–2006

    As a part of a larger study, the psychodemographic profile of Quebec pig stockpeople was described based on a sample of 48 persons working on independent farms randomly selected in the Richelieu-Saint-Hyacinthe region, and on a convenience sample of 38 others employed by 5 organizations of integrated swine production chosen among the largest ones in Québec. The 2 groups of stockpeople were described separately because of the differences between the 2 types of production. Demographic data (age, sex, level of education, training and experience in swine production, seniority on the farm) were obtained through a face-to-face interview. The personality profile was assessed using a standard personality test (French translation of the Sixteen Personality Factor Questionnaire). Both the stockpersons on independent farms and those employed by the organizations were more reserved, emotionally stable, serious, conscientious, unsentimental, controlled, introverted, and less anxious than the average person in the general population. However, multivariate analyses revealed some differences between these two groups of stock-persons (P = 0.021) as well as between the employees of the different organizations (P = 0.0038). These differences in personality profiles may reflect differences in working conditions, particularly regarding the human relationships, and in corporate cultures of the organizations. PMID:8904659

  19. Triple-drug therapy and return to work: results of a Quebec survey.

    PubMed

    Jalbert, Y

    Recent Quebec and Canadian statistics show the death rate declining among people living with HIV/AIDS. Triple-drug therapy has been shown to increase life expectancy and overall health. In the United States, a study of 55 people in Chicago living with HIV/AIDS found that 82 percent of them had considered returning to work. Another U.S. study showed that half the respondents had disclosed their sexual orientation to their employer. A survey questionnaire was prepared and distributed throughout the AIDS service organizations (ASOs) network and in two gay publications to see if the Canadian population has similar figures. The results showed that respondents under 45 years of age were more likely to want to return to work. Other conclusions of the study were that people with HIV/AIDS are not necessarily secure in their jobs, that the state of their health is their major area of concern, and that most people with HIV/AIDS do not want to return to their former jobs because of stress, discrimination, or their employer's attitude. The obligation for employers to make reasonable accommodations is a difficult concept for the employers to understand, and patients have concerns with explaining long or frequent absences from the workforce on their resumes. In 1998, the questionnaire will be distributed throughout the health and social services network. Ordering information is included. PMID:11365280

    This survey evaluates early perceptions about the use of medetomidine and atipamezole among veterinary practitioners in Quebec in 2002. Response rate was 23.5%; 71.1% of the practitioners did not use these products because of lack of information (69.3%), unavailability of the drugs in the practice (23.3%), or other reasons (7.3%), including concerns about the safety of alpha-2 agonists. Most veterinarians who used these products (70.4%) used them only rarely. Sedation by medetomidine was qualified as good (44.2%) or excellent (36%), and analgesia as good (46.5%) or average (32.7%). Waking up after atipamezole was qualified as good (47.5%) or excellent (40.9%). These perceptions indicate an opportunity for wider use of the products in veterinary practice. With more education and experience, practitioners could find medetomidine hydrochloride alone or in combination with an opioid useful for sedation, analgesia, and premedication for healthy animals. Reversal with atipamezole hydrochloride is considered effective, when residual sedation is undesirable. PMID:17824157

    Elemental abundances (including Ir), carbon and oxygen ratios in carbonates, mineral content, and thin sections have been measured in samples collected across the conodont-defined Ordovician/Silurian (O/S) boundary exposed on Anticosti Island, Quebec. The Ir concentrations ranged from 5 to a maximum at the boundary of 58 parts per trillion (ppt). However, there is no evidence, on the basis of these Ir results, for the association of a large-body-Earth impact with the O/S extinction, because the Ir concentrations, like those of most other trace elements, are simply proportional to the clay (Al) content in the carbonate sequence. The /sup 13/C//sup 12/C and /sup 18/O//sup 16/O ratios decrease abruptly at the boundary, then just as abruptly increase to a long period of higher than preboundary ratios. These patterns are probably related to the salinity in the seaway, which was shallowing up to boundary time and then deepened and developed patch-reefs. Fresh-water input from rivers would have been most influential during the shallow-water conditions. 32 references, 4 figures.

    SummaryRestoration efforts at peatlands drained for peat extraction attempt to return the hydrological conditions necessary for Sphagnum moss regeneration. One year of pre-restoration monitoring (1999) and three years of post restoration monitoring were done at the Bois-des-Bel peatland near Riviere-du-Loup, Quebec, to evaluate hydrological changes that occurred at a managed section (restored site) relative to an adjacent abandoned section of the same peatland (unrestored site). Restored site evaporation was 74%, 74%, and 98% of unrestored site evaporation in 2000, 2001, and 2002, while runoff at the restored site was 83%, 30%, and 12% of unrestored site runoff over the same period. Seasonal soil volume change (swelling and shrinking of the peat) was evident at the restored site indicating rewetting of the peat profile despite the prolonged period between site abandonment and the initiation of the restoration measures (19 years). Site rewetting may have benefited from the relatively deep layer of residual peat (around 1.5 m). Higher seasonal mean water table and soil moisture were observed at the restored site relative to the unrestored site in 2000 through 2002 along with increased seasonal variability at the former location. Mean soil-water pressure was also higher than at the unrestored site and the range decreased, both spatially and on a seasonal and daily basis. The restoration techniques contributed to the recovery of hydrological conditions necessary for Sphagnum recolonization, though successful application at different sites may be limited by specific peat and climate characteristics.

    During a seven-month survey from May to November 1985, 624 victims injured from three- or four-wheeled all-terrain vehicles (ATVs) were observed in the emergency rooms of 10 regional hospitals in Quebec. A total of 1,100 injuries were identified, including 3 fatal and 104 serious to critical injuries (AIS greater than or equal to 3). These injuries were to the lower limb (29%), the upper limb (28%), the head, neck, and face (26%), and the thorax, abdomen, and pelvis (18%). Close to one-half (45%) of the victims were 19 years old and less; 54% reported wearing helmets. Ten percent of the victims were hospitalized for an average period of 8 days. In 70% of the cases, the vehicle overturned: half of these vehicles turned on the side, 27% toward the back, and 19% flipped forward. Two-thirds of persons injured were involved in accidents in which no external objects were hit by the vehicle; these accidents typically involved vehicle overturns, both on hills and on level ground. Ninety-five percent of the vehicles were in good mechanical condition. The use of these vehicles presents a danger whether used by a child or an adult, by an experienced or an inexperienced rider. The average user may not be aware that three- and four-wheel ATVs demand considerable skill and caution. We suggest the use of accident reconstruction studies for possible engineering solutions.

    The Matoush uranium deposit is situated in the Paleoproterozoic Otish Basin, northern Quebec, Canada, and is hosted by the Indicator Formation sandstones. Its sheet-like ore bodies are closely associated with the steeply dipping Matoush Fracture, which hosts mafic dykes and minor quartz-feldspar-tourmaline pegmatites. Regional diagenesis, involving oxidizing basinal fluids (δ2H ˜-15‰, δ18O ˜8‰), produced mostly illite and possibly leached U from accessory phases in the Indicator Formation sandstones. The bimodal Matoush dyke intruded the Indicator Formation along the Matoush Fracture, and the related metasomatism produced Cr-rich dravite and muscovite in both the dyke and the proximal sandstones. Uraninite formed when U6+ in the basinal brine was reduced to U4+ in contact with the mafic dyke and by Fe2+ in Cr-dravite and Cr-muscovite, and precipitated together with eskolaite and hematite. Because of its unique characteristics, the Matoush deposit cannot be easily classified within the generally accepted classification of uranium deposits. Two of its main characteristics (unusual reduction mechanism, structural control) do not correspond to the sandstone-hosted group of deposits (unconformity type, tabular, roll front), in spite of uranium being derived from the Otish Group sandstones.

    As social elements of our environment, mass media are regarded as determinants of individual and population beliefs, social norms and habits. Since it is recognized that they influence population health, this study aims to obtain a better portrait of Quebec media content regarding physical activity and nutrition messages on a public health level. First, we analyzed the content of fictional television shows (n = 1 3) and advertisements broadcast during those shows (n = 68). Second, we reviewed the content of La Presse newspaper and of French television Société Radio-Canada from 1986 to 2005 with regard to physical activity and nutrition messages. Our results indicate a difference between how men and women are portrayed on French television, with women more often being shown as underweight and men as at or above healthy body weight. The results also show that during the 20-year period of the reviewed content, there were fewer messages about physical activity than about nutrition. To be successful in their goal of improving population health, mass media should address both subjects together in their messages. PMID:19507724

    In 1972 there were outbreaks of eastern equine encephalitis in the Eastern Townships, Quebec, Canada and in Connecticut, USA. Climatic data including Northern Hemisphere synoptic charts were examined. The findings indicate that the virus could have been brought to Lac Brome by infected mosquitoes carried on surface winds from Meriden, Connecticut, on the night of August 22-23, 1972. The distance of 400 km would have been covered in 14-16 h at a speed of 25-30 km h-1 and at a temperature of 15 degrees C and higher. The first case was recorded 13 days later on September 5, 1972. The outbreak at Meriden, Connecticut started on August 21, 1972. On August 7, 1972 southwesterly winds blew along the Atlantic coast at heights up to 1.5 km. Infected mosquitoes could have been carried on the wind from Cape May, New Jersey, Delaware-Maryland-Virginia peninsula, North Carolina or Georgia. Flights would have been at 17 degrees-20 degrees C and lasted 5-6, 9-10, 14-16 and 20-26 h depending on the origin. The arrival on August 8, 1972 coincided with a cold front moving from the northwest through Connecticut. Culiseta melanura is regarded as the mosquito species most likely to have been involved in the transmission of infection. PMID:2563337

    Fecal samples from diarrheic and nondiarrheic dairy calves (1 to 3 weeks old) from 12 regions of Quebec, collected between 1992 and 1994, were screened for group A bovine rotavirus (BRV) using a combination of 2 VP6-specific monoclonal antibodies (MAbs) in an enzyme-linked immunosorbent assay (ELISA). The overall prevalence of BRV infection was 26.4% (107/405). In diarrheic calves, BRV infection reached 74.3% (55/74), but only 15.7% (52/331) in nondiarrheic calves. BRV-positive samples were serotyped by enzyme-linked immunosorbent assay (ELISA) using G6 and G10 specific MAbs. The analysis of 107 field samples revealed that, in diarrheic calves, 34.5% (19/55) were G6, 27.2% (15/55) were G10, 9% (5/55) were G6 and G10 positive, and 29.9% (16/55) were G6 and G10 negative. In nondiarrheic calves, 19.2% (10/52) were G6, 19.2% (10/52) were G10, 7.6% (4/52) were G6 and G10 positive, and 53.6% (28/52) were G6 and G10 negative. Rotavirus dsRNA was extracted from BRV-positive samples and examined by polyacrilamide gel electrophoresis (PAGE). Of 107 samples tested, 74 (69.1%) were positive, and all the samples demonstrated a typical group A rotavirus migration pattern. PMID:8521359

The model uses specified input rates from background advective flows and emissions from the Alcan aluminum smelting facility at Beauharnois to deduce atmospheric concentrations and rates of wet and dry deposition to the three segment lake. Concentrations in water and sediment as well as relevant mass fluxes and residence times are computed and compared satisfactorily with monitoring data for five of the seven PAHs. Underestimation of concentrations for anthracene and phenanthrene is attributed to unquantified additional sources. The sources of the PAH burden in the lake are apportioned, and the implications of these results are discussed including likely response times to changes in loadings. It is suggested that this mass balance approach is more widely applicable to situations in which water bodies are impacted by a variety of contaminant sources. PMID:10834368

    A multi community environment-and-health study among six of the nine communities of Eeyou Istchee in northern Quebec, Canada provided greater insight into iodine intake levels among these Cree First Nation communities. Using data from this large population-based study, descriptive statistics of measured urinary iodine concentrations (UICs) and iodine-creatinine ratios (stratified by age, sex, community of residence, and water consumption) were calculated, and the associations between independent variables and iodine concentration measures were examined through a general linear model. Traditional food consumption contributions were examined through Pearson partial correlation tests and linear regression analyses; and the importance of water sources through ANOVA. Generally speaking, urinary iodine levels of Eeyou Istchee community members were within the adequate range set out by the World Health Organization, though sex and community differences existed. However, men in one community were considered to be at risk of iodine deficiency. Older participants had significantly higher mean iodine-creatinine ratios than younger participants (15-39 years = 90.50 μmol mol(-1); >39 years = 124.52 μmol mol(-1)), and consumption of beaver (Castor canadensis) meat, melted snow and ice, and bottled water were predictive of higher iodine excretion. It is concluded that using both urinary iodine indicators can be helpful in identifying subgroups at greater risk of iodine deficiency. PMID:25764377

  10. Collaboration between general practitioners (GPs) and mental healthcare professionals within the context of reforms in Quebec

    Background In the context of the high prevalence and impact of mental disorders worldwide, and less than optimal utilisation of services and adequacy of care, strengthening primary mental healthcare should be a leading priority. This article assesses the state of collaboration among general practitioners (GPs), psychiatrists and psychosocial mental healthcare professionals, factors that enable and hinder shared care, and GPs’ perceptions of best practices in the management of mental disorders. A collaboration model is also developed. Methods The study employs a mixed-method approach, with emphasis on qualitative investigation. Drawing from a previous survey representative of the Quebec GP population, 60 GPs were selected for further investigation. Results Globally, GPs managed mental healthcare patients in solo practice in parallel or sequential follow-up with mental healthcare professionals. GPs cited psychologists and psychiatrists as their main partners. Numerous hindering factors associated with shared care were found: lack of resources (either professionals or services); long waiting times; lack of training, time and incentives for collaboration; and inappropriate GP payment modes. The ideal practice model includes GPs working in multidisciplinary group practice in their own settings. GPs recommended expanding psychosocial services and shared care to increase overall access and quality of care for these patients. Conclusion As increasing attention is devoted worldwide to the development of optimal integrated primary care, this article contributes to the discussion on mental healthcare service planning. A culture of collaboration has to be encouraged as comprehensive services and continuity of care are key recovery factors of patients with mental disorders. PMID:23730332

    The 11q21-22 region is of interest for schizophrenia because several candidate genes are located in this section of the genome. The 11q21-22 region, including DRD2, was surveyed by linkage analysis in a sample (N = 242) made of four large multigenerational pedigrees densely affected by schizophrenia (SZ) and eight others by bipolar disorder (BP). These pedigrees were ascertained in a large area of Eastern Quebec and Northern New Brunswick and are still being extended. Family members were administered a {open_quotes}consensus best-estimate diagnosis procedure{close_quotes} (DSM-III-R criteria) blind to probands and relatives` diagnosis and to pedigree assignment (SZ or BP). For linkage analysis, 11 microsatellite polymorphism (CA repeat) markers, located at 11q21-22, and comprising DRD2, were genotyped. Results show no evidence of a major gene for schizophrenia. However, a maximum lod score of 3.41 at the D11S35 locus was observed in an affected-only analysis of one large SZ family, pedigree 255. Whether or not the positive linkage trend in pedigree 255 reflects a true linkage for a small proportion of SZ needs to be confirmed through the extension of this kindred and through replication. 36 refs., 2 tabs.

    Non-cervical anogenital cancers (i.e. anal, vulvar, vaginal and penile cancers) associated with the human papillomavirus (HPV), for which HPV is known to be the necessary cause of carcinogenesis, are poorly documented due to their relatively low incidence rate. The aim of this study is to describe the incidence rates of these cancers between 1984 and 2001, and their relative survival probabilities, in Quebec (Canada) between 1984 and 1998. The incidence of these cancers is on the rise, particularly anal cancer in women and, more recently (since 1993-95), vulvar cancer. Between 1984-86 and 1993-95, the 5-year relative survival probability for men with anal cancer decreased from 57% to 46%, while that for penile cancer dropped from 75% to 59%. However, during the same period, the 5-year relative survival probability for women with anal cancer rose from 56% to 65%, and remained stable for cervical and vulvar cancers, at 74% and 82%, respectively.

    OBJECTIVE: To characterize the incidence and duration of hospitalization due to diarrhea and to assess the proportion of hospitalizations that are attributed to rotavirus-associated diarrhea. DESIGN: Retrospective study of hospitalization data. SETTING: Hospitals located in Quebec. POPULATION STUDIED: Children from one to 59 months of age who were discharged from hospital from April 1, 1985 to March 31, 1998. MAIN RESULTS: There were 63,827 hospitalizations for diarrhea over the study period, for an average of 4910 hospitalizations/year. The epidemic curve showed a periodicity with regular alternation of high and low annual peaks. The number of hospitalizations for rotavirus-associated diarrhea was estimated according to three different methods. The estimates varied between 1353 and 1849 hospitalizations due to rotavirus-associated diarrhea/year over the 13-year period, with good agreement between the results of the three methods for a one-month to five years of age incidence of 320 hospitalizations for rotavirus-associated diarrhea/100,000 children. The average duration of hospital stay decreased from 5.2 days in 1985 to 3.3 days in 1998. CONCLUSIONS: The present article shows the importance of diarrhea hospitalizations among children and the alternating peak-year periodicity. PMID:18159396

    OBJECTIVES. This study assessed the effectiveness of a 4-year program of bicycle helmet promotion that targeted elementary school children in one region of Quebec. The program revolved primarily around persuasive communication and community organization, combining standard educational activities and activities to facilitate helmet acquisition and use. METHODS. Helmet use was compared between more than 8000 young cyclists in municipalities exposed or not exposed to the program. Factors influencing helmet use were controlled through the use of multivariate analyses. RESULTS. Helmet use increased from 1.3% before program implementation to 33% in 1993. The program was clearly effective in most cycling circumstances and for various groups of children. However, the benefits of the program were unequally distributed; the program was one third as effective in poorer municipalities as in "average-rich" ones. CONCLUSIONS. This community-based program that combined various types of activities appeared to be effective. New intervention models are needed to ensure an equitable distribution of benefits. PMID:8561241

    Quebec Urban Community (QUC) has selected Global Predictive Real-Time Control (GP-RTC) as the most efficient approach to achieve environmental objectives defined by the Ministry of Environment. QUC wants to reduce combined sewer overflows (CSOs) frequency to the St Lawrence river to two events per summer period in order to reclaim the use of Jacques-Cartier Beach for recreational activities and sports of primary contact. QUC's control scheme is based on the Certainty Equivalent Control Open Loop Feedback (CEOLF) strategy which permits one to introduce, at each control period, updated measurements and meteorological predictions. A non-linear programming package is used to find the flow set points that minimise a multi-objective (cost) function, subjected to linear equality and inequality constraints representing the physical and operational constraints on the sewer network. Implementation of GP-RTC on QUC's westerly network was performed in the summer of 1999 and was operational by mid-August. Reductions in overflow volumes with GP-RTC compared to static control are attributed to the optimal use of two existing tunnels as retention facilities as well as the maximal use of the wastewater treatment plant (WWTP) capacity.

    A hydrogeological study was conducted in Potsdam sandstones on the international border between Canada (Quebec) and the USA (New York). Two sandstone formations, arkose and conglomerate (base) and well-cemented quartz arenite (upper), underlie the study area and form the major regional aquifer unit. Glacial till, littoral sand and gravel, and marine silt and clay discontinuously overlie the aquifer. In both sandstone formations, sub-horizontal bedding planes are ubiquitous and display significant hydraulic conductivities that are orders of magnitude more permeable than the intact rock matrix. Aquifer tests demonstrate that the two formations have similar bulk hydrologic properties, with average hydraulic conductivities ranging from 2 ?? 10-5 to 4 ?? 10-5 m/s. However, due to their different lithologic and structural characteristics, these two sandstones impose rather different controls on groundwater flow patterns in the study area. Flow is sustained through two types of fracture networks: sub-horizontal, laterally extensive fractures in the basal sandstone, where hydraulic connectivity is very good horizontally but very poor vertically and each of the water-bearing bedding planes can be considered as a separate planar two-dimensional aquifer unit; and the more fractured and vertically jointed system found in the upper sandstone that promotes a more dispersed, three-dimensional movement of groundwater. ??

    A sample of anorthosite from the granulite facies Morin Shear Zone (Quebec, Canada) was investigated for crystal preferred orientation and elastic anisotropy. Time-of-flight neutron diffraction data obtained with the HIPPO diffractometer at LANSCE were analyzed with the Rietveld method to obtain orientation distribution functions of the principal phases (plagioclase, clinopyroxene and orthopyroxene). Texture and microstructures are compatible with the plastic deformation of the aggregate under high-T conditions. All mineral phases depict a significant preferred orientation that could be related to the general top-to-the north shearing history of the Morin Shear Zone. Texture patterns suggest that (010)[001] in plagioclase and (110)[001] in clinopyroxene are likely dominant slip systems. Using preferred orientation data P- and S-waves velocities and elastic anisotropy were calculated and compared with previous studies to explore elastic properties of rocks with different pyroxene-plagioclase mixtures. P-wave velocity, S-wave splitting and anisotropy increase with clinopyroxene content. Seismic anisotropy is linked to the texture symmetry which can lead to large deviations between actual anisotropy and that measured along Cartesian XYZ sample directions (lineation/foliation reference frame). This is significant for the prediction and interpretation of seismic data, particularly for monoclinic or triclinic texture symmetries.

    Field evidence supports the relatively widespread presence of nonmarine facies within the basal Potsdam formation of the Adirondack border areas of northern New York, southeastern Ontario, and southwestern Quebec. Detailed observations of areal extent, analysis of sedimentary structures and paleocurrent directions, and petrographic studies have been combined with the paleomagnetic determination of the temporal relationships of these strata to establish depositional patterns and facies trends within basal Potsdam units. Four distinct nonmarine lithofacies have been identified: massive matrix-supported conglomerate, stratified framework-supported conglomerate, conglomerate-arkose, and pebble conglomerate-arkose fining-upward sequences, interpreted to represent debris flows, proximal gravelly braided-stream deposits, intermediate to distal gravelly braided-stream deposits, and proximal sandy braided-stream deposits, respectively. Facies of eolian or possibly tidal, and shallow marine origin have also been identified at the base of the Potsdam sequence. Most basal Potsdam sediments are compositionally and texturally immature, derived directly from the crystalline detritus of the extensively weathered Precambrian surface and regoliths that may have locally developed on the craton. The desert-like environment of the Precambrian surface allowed for rapid transport and deposition of relatively unweathered sediments and the subsequent construction of a braided alluvial plain system. Field relations and evidence derived from consideration of the paleomagnetic properties in five localities of fine-grained alluvium suggest that terrestrial Potsdam deposition in the Early and Middle Cambrian largely preceded the marine transgression that deposited the thick, shallow marine units typifying most of the Potsdam sequence.

    The 'common knowledge' defence is a legal strategy which has been successfully used by defendant tobacco companies to avoid legal responsibility for the harms caused by smoking. Tobacco companies have hired professional historians to try to persuade courts about a longstanding high level of public awareness regarding the risks of tobacco use. To support this argument, they have used archival news clippings and media reports. Two historians were hired by tobacco companies to offer this defence during a recent class action trial in Canada, following which they were required to submit to the court the collection of media materials which had been gathered by history students to assist their testimony. Included in this collection were tobacco advertisements and other news items about tobacco products which the students had inadvertently also collected. Quantifying this collection reveals that even by the tobacco industry's own construct, the information environment surrounding Quebec smokers in the middle 20th century included more prosmoking messages than information about the risks of smoking.

    The Quebec Patient Smart Card Project is a Provincial Government initiative under the responsibility of the Rgie de l'assurance-maladie du Québec (Quebec Health Insurance Board). Development, implementation, and assessment duties were assigned to a team from Université Laval, which in turn joined a group from the Direction de la santé publique du Bas-St-Laurent in Rimouski, where the experiment is taking place. The pilot project seeks to evaluate the use and acceptance of a microprocessor card as a way to improve the exchange of clinical information between card users and various health professionals. The card can be best described as a résumé containing information pertinent to an individual's health history. It is not a complete medical file; rather, it is a summary to be used as a starting point for a discussion between health professionals and patients. The target population is composed of persons 60 years and over, pregnant women, infants under 18 months, and the residents of a small town located in the target area, St-Fabien, regardless of age. The health professionals involved are general practitioners, specialists, pharmacists, nurses, and ambulance personnel. Participation in the project is on a voluntary basis. Each health care provider participating in the project has a personal identification number (PIN) and must use both an access card and a user card to access information. This prevents unauthorized access to a patient's card and allows the staff to sign and date information entered onto the patient card. To test the microprocessor card, we developed software based on a problem-oriented approach integrating diagnosis, investigations, treatments, and referrals. This software is not an expert system that constrains the clinician to a particular decisional algorithm. Instead, the software supports the physician in decision making. The software was developed with a graphical interface (Windows 3.1) to maximize its user friendliness. A version of the

  4. Black spruce growth forms as a record of a changing winter environment at treeline, Quebec, Canada

    The environmental conditions prevailing at treeline in subarctic Quebec have been reconstructed over the past 400 yr through a comparative analysis of tree rings and growth forms of black spruce (Picea mariana (Mill.) B.S.P.). Because black spruce growth forms are closely associated with the winter environment, they are a direct response to conditions of low temperature and windblown snow abrasion affecting living tissues at the snow-air interface. The age structure of supranival shoot populations was closely associated with periods of higher stem survival in winter most likely under snowier and windless conditions. Spruce growth on slopes and in the valley revealed periods of low tree-ring growth between 1601 and 1663 and between 1700 and 1904, respectively. A long-lasting period of low radial growth 1697 and 1939 prevailed in the hilltop site. During the 20th century, spruce height increased from 0.8 to 1.6 m on slopes and in the valley, while the basal level of abrasion from windblown snow increased from 0.1 to 0.5 m, suggesting an increasing trend towards warmer and snowier conditions. Abraded spruces growing during the Little Ice Age (1570-1880) were replaced by symmetrical trees during the 20th century. Supranival skirted and whorled spruces which dominated on the hilltop site during the 16th century reverted to infranival cushion and mat growth forms during the Little Ice Age. These stunted spruces were unable to recover during the recent warming because of their inability to catch enough drifting snow to allow vertical growth.

  5. Volcanic red-bed copper mineralisation related to submarine basalt alteration, Mont Alexandre, Quebec Appalachians, Canada

    2007-11-01

    Two types of native copper occur in Upper Silurian basaltic rocks in the Mont Alexandre area, Quebec Appalachians: (1) type 1 forms micrometric inclusions in plagioclase and is possibly magmatic in origin, whereas (2) type 2 occurs as coarse-grained patches rimmed by cuprite in altered porphyritic basalt. Type 1 has higher contents of sulphur (2,000-20,263 ppm) and arsenic (146-6,017 ppm), and a broader range of silver abundances (<65-2,186 ppm Ag) than type 2 (149-1,288 ppm S, <90-146 As, <65-928 ppm Ag). No mineral inclusions of sulphide or arsenide in native copper were observed at the electron-microprobe scale. Primary igneous fabrics are preserved, but the basaltic flows are pervasively oxidised and plagioclase is albitised. Chlorite replaces plagioclase and forms interstitial aggregates in the groundmass and has Fe/(Fe+Mg) ratios ranging from 0.29 to 0.36 with calculated temperatures between 155°C and 182°C. Copper sulphides in vacuoles and veinlets are associated with malachite, fibro-radiating albite and yarrowite (Cu9S8 with up to 0.3 wt% Ag). Bulk-rock concentrations of thallium and lithium range from 70 to 310 ppb and 10 to 22 ppm, respectively, and thallium is positively correlated with Fe2O3. Such concentrations of thallium and lithium are typical of spilitisation during heated seawater-basalt interaction. Spilitisation is consistent with the regional geological setting of deepwater-facies sedimentation, but is different from current models for volcanic red-bed copper, which indicate subaerial oxidation of volcanic flows. The volcanic red-bed copper model should be re-examined to account for native copper mineralisation in basalts altered by warm seawater.

    Purpose Some evidence suggests that low maternal vitamin D status adversely affects perinatal health but few studies have examined cord blood vitamin D status. This project aimed to determine the association between the cord blood concentration of 25-hydroxyvitamin D [25(OH)D] and neonatal outcomes. Methods A nested case–control study was conducted in Quebec City, Canada from 2005 to 2010. Included were 83 cases of low birthweight (LBW; <2500 g), 301 cases of small for gestational age (SGA; <10th percentile), 223 cases of preterm birth (PTB; <37 weeks’ gestation), and 1027 controls. Levels of 25(OH)D were determined by chemiluminescence immunoassay. Adjusted odds ratios (OR) and 95 % confidence intervals (CI) were estimated with logistic regression. Results Cord blood [25(OH)D] <50 nmol/L was associated with a lower risk of LBW compared to [25(OH)D] ≥75 nmol/L (OR 0.47 95 % CI 0.23–0.97). For 25(OH)D levels 50–75 nmol/L, a significant association was not demonstrated (OR 0.58, 95 % CI 0.34–1.01). No significant associations were observed between [25(OH)D] and either SGA or PTB after adjustment. Conclusions Although our findings suggest that [25(OH)D] <50 nmol/L is associated with reduced risk of having a LBW infant, prenatal vitamin D recommendations require an examination of the literature that considers the full spectrum of maternal and neonatal outcomes.

    Synchrotron high-resolution powder X-ray-diffraction (HRPXRD) data and Rietveld structure refinement were used to examine a two-phase intergrowth of genthelvite, ideally Zn{sub 8}[Be{sub 6}Si{sub 6}O{sub 24}]S{sub 2}, from the alkaline intrusive complex at Mont Saint-Hilaire, Quebec, where genthelvite occurs in nepheline syenite pegmatites. The structural parameters obtained for the two phases are slightly different from each other. The unit-cell parameters are 8.119190(7) {angstrom} (51% phase 1) and 8.128914(9) {angstrom} (49% phase 2). The refinement gives the chemical formulae and interstitial M cation in terms of Zn and Mn (the Fe content is practically zero) for the Mn-poor genthelvite phase 1 as (Zn{sub 7.8}Mn{sub 0.2}){Sigma}{sub 8}[Be{sub 6}Si{sub 6}O{sub 24}]S{sub 2}, and the Mn-rich genthelvite phase 2 as (Zn{sub 7.0}Mn{sub 1.0}){Sigma}{sub 8}[Be{sub 6}Si{sub 6}O{sub 24}]S{sub 2}. These formulae are comparable to the Mn-poor and Mn-rich phases obtained by electron-microprobe analysis. The intergrowth indicates that diffusion is absent among the interstitial M cations of similar size (Zn{sup 2+}, Fe{sup 2+} and Mn{sup 2+}). Such intergrowths may form under distinct f(O{sub 2}) conditions and probably low temperature of crystallization that inhibits diffusion of M cations.

    Background Enrolling patients in studies of pancreatic ductal adenocarcinoma (pdac) is challenging because of the high fatality of the disease. We hypothesized that a prospective clinic-based study with rapid ascertainment would result in high participation rates. Using that strategy, we established the Quebec Pancreas Cancer Study (qpcs) to investigate the genetics and causes of pdac and other periampullary tumours (pats) that are also rare and underrepresented in research studies. Methods Patients diagnosed with pdac or pat were introduced to the study at their initial clinical encounter, with a strategy to enrol participants within 2 weeks of diagnosis. Patient self-referrals and referrals of unaffected individuals with an increased risk of pdac were also accepted. Family histories, epidemiologic and clinical data, and biospecimens were collected. Additional relatives were enrolled in families at increased genetic risk. Results The first 346 completed referrals led to 306 probands being enrolled, including 190 probands affected with pdac, who represent the population focus of the qpcs. Participation rates were 88.4% for all referrals and 89.2% for pdac referrals. Family history, epidemiologic and clinical data, and biospecimens were ascertained from 91.9%, 54.6%, and 97.5% respectively of patients with pdac. Although demographics and trends in risk factors in our patients were consistent with published statistics for patients with pdac, the qpcs is enriched for families with French-Canadian ancestry (37.4%), a population with recurrent germ-line mutations in hereditary diseases. Conclusions Using rapid ascertainment, a pdac and pat research registry with high participation rates can be established. The qpcs is a valuable research resource and its enrichment with patients of French-Canadian ancestry provides a unique opportunity for studies of heredity in these diseases. PMID:25908910

    Abstract Objective To determine health care professionals’ understanding of the current legal status of different end-of-life practices and their future legal status if medical aid in dying were legalized, and to identify factors associated with misunderstanding surrounding the current legal status. Design Cross-sectional survey using 6 clinical scenarios developed from a validated European questionnaire and from a validated classification of end-of-life practices. Setting Quebec. Participants Health care professionals (physicians and nurses). Main outcome measures Perceptions of the current legal status of the given scenarios and whether or not the practices would be authorized in the event that medical aid in dying were legalized. Results Among the respondents (n = 271, response rate 88.0%), more than 98% knew that the administration or prescription of lethal medication was currently illegal. However, 45.8% wrongly thought that it was not permitted to withdraw a potentially life-prolonging treatment at the patient’s request, and this misconception was more common among nurses and professionals who had received their diplomas longer ago. Only 39.5% believed that, in the event that medical aid in dying were legalized, the use of lethal medication would be permitted at the patient’s request, and 34.6% believed they would be able to give such medication to an incompetent patient upon a relative’s request. Conclusion Health care professionals knew which medical practices were illegal, but some wrongly believed that current permitted practices were not legal. There were various interpretations of what would or would not be allowed if medical aid in dying were legalized. Education on the clinical implications of end-of-life practice legislation should be promoted. PMID:26052600

    The increasing number of studies on the determination of natural methane in groundwater of shale gas prospection areas offers a unique opportunity for refining the quantification of natural methane emissions. Here methane emissions, computed from four potential sources, are reported for an area of ca. 16,500km(2) of the St. Lawrence Lowlands, Quebec (Canada), where Utica shales are targeted by the petroleum industry. Methane emissions can be caused by 1) groundwater degassing as a result of groundwater abstraction for domestic and municipal uses; 2) groundwater discharge along rivers; 3) migration to the surface by (macro- and micro-) diffuse seepage; 4) degassing of hydraulic fracturing fluids during first phases of drilling. Methane emissions related to groundwater discharge to rivers (2.47×10(-4) to 9.35×10(-3)Tgyr(-1)) surpass those of diffuse seepage (4.13×10(-6) to 7.14×10(-5)Tgyr(-1)) and groundwater abstraction (6.35×10(-6) to 2.49×10(-4)Tgyr(-1)). The methane emission from the degassing of flowback waters during drilling of the Utica shale over a 10- to 20-year horizon is estimated from 2.55×10(-3) to 1.62×10(-2)Tgyr(-1). These emissions are from one third to sixty-six times the methane emissions from groundwater discharge to rivers. This study shows that different methane emission sources need to be considered in environmental assessments of methane exploitation projects to better understand their impacts. PMID:27267724

    BACKGROUND: Public health authorities in Quebec have responded to the progressive emergence of Lyme disease (LD) with surveillance activities and education for family physicians (FPs) who are key actors in both vigilance and case management. OBJECTIVES: To describe FPs’ clinical experience with LD, their degree of knowledge, and their practices in two areas, one with known infected tick populations (Montérégie) and one without (regions nearby Montérégie). METHODS: In the present descriptive cross-sectional study, FPs were recruited during educational sessions. They were asked to complete a questionnaire assessing their clinical experience with Lyme disease, their knowledge of signs and symptoms of LD, and their familiarity with accepted guidelines for diagnosing and treating LD in two clinical scenarios (tick bite and erythema migrans). RESULTS: A total of 201 FPs participated, mostly from Montérégie (n=151). Overall, results revealed a moderate lack of knowledge and suboptimal practices rather than systematically insufficient knowledge or inadequate practices. A majority of participants agreed to more education on LD. As expected, FPs from Montérégie had a higher clinical experience with tick bites (57% versus 25%), better knowledge of LD endemic areas in Canada and erythema migrans characteristics, and better management of erythema migrans (72% versus 50%). CONCLUSION: The present study documented the inappropriate intention to order serology tests for tick bites and the unjustified intention to use tick analysis for diagnostic purposes. Such practices should be discouraged because they are unnecessary and overuse collective laboratory and medical resources. In addition, public health authorities must pursue their education efforts regarding FPs to optimize case management. PMID:26236357

  12. Paleomagnetic Dating of Holocene Rapidly Deposited Layers From the Saguenay Fjord, Quebec, Canada

    The Saguenay Fjord (Quebec, Canada) area has been struck by several natural disasters in the last 350 years. Among these disasters are the 1663 (M~7) and 1988 (M=6) earthquakes as well as the flood of 1996. These events triggered the deposition of thick layers, ranging from a few centimetres to about sixteen metres in the Saguenay Fjord inner basin. A 38 m-long piston core (core MD99-2222) was sampled from the deepest part of the Saguenay Fjord inner basin as part of the 1999 IMAGES-V (International Marine Past Global Change Study) program in order to determine the frequency of natural hazards such as earthquakes during the Holocene. Based on physical, magnetic and sedimentological data, we identified at least 14 rapidly deposited layers (RDL) in core MD99-2222. These layers contrast sharply from the dark grey bioturbated "background" sediments and are visually recognizable by their light color due to higher CaCO3 content resulting from the incorporation of light grey, slightly calcareous, Laflamme Sea Clays. In addition, most RDL have a sandy base with corresponding peaks in density and magnetic susceptibility, along with generally lower paleomagnetic inclinations that indicate an energetic depositional process where the magnetic particles are plastered horizontally because of high flow velocity and rapid sediment accumulation. Homogeneous, light grey, clayey silt beds generally overlie the sandy bases. Unfortunately, because CaCO3 dissolution occurs in the Saguenay Fjord sediments, little material is available for radiocarbon dating, making the setting of a robust chronology difficult. Here, we will show how changes in the Earth's magnetic field intensity and direction were used, in conjunction with 210Pb dating, one AMS 14C date and the recognition of a turbidite associated with the 1663 earthquake, to construct the age model for core MD99-2222 and thus to date all the RDL.

    Mineral carbonation is considered a permanent option to capture and store atmospheric CO2. This reaction occurs naturally under ambient conditions in ultramafic mining and milling waste. In the region of Thetford Mines, Quebec, chrysotile mining has produced approximately 0.8 Gt of magnesium-rich milling waste, which mainly consists of poorly sorted ultramafic rock fragments (< 10 cm) and chrysotile fibers. To quantify the amount of CO2 that can be captured in the mine wastes of Thetford Mines, two experimental pilot-scale tailings cells were constructed and instrumented for measuring soil temperature, volumetric water content, gas pressure and gas composition, with ambient conditions recorded by an autonomous meteorological station. The cells were monitored for water geochemistry, carbon content and mineralogy, with the objective to better understand the mineral carbonation processes under natural conditions and to propose a conceptual model for mineral carbonation at the pilot scale. To validate this model, numerical simulations with the MIN3P reactive transport code have been carried out. The chemical composition of the cell leachate (pH > 10, Mg from 85 to 140 mg.L-1, and high total alkalinity from 260 to 300 mg.L-1 CaCO3) is consistent with active CO2 mineralization reactions within the cell. SEM analyses show precipitation of dypingite with a lamellar texture and cemented grain surfaces. The milling waste contains up to 1.2% C, which indicates CO2 sequestration by mineral carbonation. Measured CO2 concentrations in the interstitial air are also ten times lower than in the atmosphere. Analysis of seasonal variations in fluid flow and heat transfer (essentially by thermal conduction) shows that molecular diffusion is the main process for CO2 supply within the experimental cells. These observations have helped develop a conceptual model for mineral carbonation in the wastes and were used to calibrate the reactive transport model.

    This study aims to translate and cross-culturally adapt the Moroccan version of the Quebec Back Pain Disability Scale (QDS) and to investigate its reliability and validity in Moroccan patients with low back pain (LBP). The translation and cross-cultural adaptation of the QDS were developed in agreement with published guidelines. The QDS was translated by use of the forward and backward translation procedure. After pretest, it was validated in 64 Moroccan patients with LBP. The QDS was recorded twice, at baseline visit and 72 h later. Reproducibility was evaluated using intraclass correlation coefficient (ICC) and Bland and Altman method. Internal consistency was measured by Cronbach α coefficient. Ceiling and floor effects were assessed. Validity was measured by correlating the scores of the Moroccan QDS with visual analogue scale (VAS) for Pain, Disability VAS, Schober test, fingertip-floor measurement and the Moroccan version of the Roland Morris Disability Questionnaire (RMDQ) by means of the Spearman rank correlation coefficient. Association with gender and education level was also studied. Reliability was excellent with an ICC (type 2.1) of 0.959 (CI 95%: 0.934-0.975). The internal consistency was high with a Cronbach α of 0.979. The Bland and Altman method showed homogenous distribution of the differences, with no systematic trend. There were no floor or ceiling effects. The correlation between QDS and RMDQ was very good (r = 0.664; p ≤ 0.001). There was no correlation between QDS and the other variables. Accordingly, the Moroccan version of QDS has good reproducibility, internal consistency and validity for the assessment of disability in Moroccan-speaking patients with LBP. PMID:22349881

    The cheese microbial ecosystem is complex, and the presence of non-starter adventitious microorganisms in milk may have an influence on the organoleptic characteristics of cheese. The aim of this study was to analyze the composition and diversity of the fungal flora of raw milk destined for cheesemaking from 19 dairy farms in Quebec and to monitor their evolution throughout ripening. Six hundred ten yeast and mold isolates were collected from raw milk and raw milk cheeses over a 9-month period. Based on the sequences of the rDNA ITS1-5.8S-ITS2 region, 67% of the raw milk isolates were yeasts, which were assigned to 37 species across 11 genera, while 33% were molds, which were assigned to 33 species across 25 genera. A semi-quantitative analysis of the yeasts and molds in the raw milk from four farms was performed over a 5-month period. The composition and diversity of the fungal microflora were totally different for each farm, each of which had a unique species profile. To determine whether adventitious yeast strains from the milk could develop in raw milk cheese, a multilocus-sequence-typing (MLST) analysis was performed on 13 Issatchenkia orientalis (syn. Pichia kudriavzevii, anamorph: Candida krusei) isolates. The same MLST genotypes were identified for strains independently isolated from raw milk and raw milk cheese from a farm processing its own milk. This study contributes to the understanding of the natural fungal microflora of raw milk and suggests that non-starter yeasts and molds can transfer from raw milk to raw milk cheese and may influence cheese ripening.

    Background Although interruption of endemic measles was achieved in the Americas in 2002, Quebec experienced an outbreak in 2011 of 776 reported cases; 80% of these individuals had not been fully vaccinated. We analyzed readers’ online responses to Canadian news articles regarding the outbreak to better understand public perceptions of measles and vaccination. Methods We searched Canadian online English and French news sites for articles posted between April 2011 and March 2012 containing the words “measles” and “Quebec”. We included articles that i) concerned the outbreak or related vaccination strategies; and ii) generated at least ten comments. Two English and two bilingual researchers coded the unedited comments, categorizing codes to allow themes to emerge. Results We analyzed 448 comments from 188 individuals, in response to three French articles and six English articles; 112 individuals expressed positive perceptions of measles vaccination (2.2 comments/person), 38 were negative (4.2 comments/person), 11 had mixed feelings (1.5 comments/person), and 27 expressed no opinion (1.1 comments/person). Vaccine-supportive themes involved the success of vaccination in preventing disease spread, societal responsibility to vaccinate for herd immunity, and refutation of the autism link. Those against measles vaccination felt it was a personal rather than societal choice, and conveyed a distrust of vaccine manufacturers, believing that measles infection is not only safe but safer than vaccination. Commenters with mixed feelings expressed uncertainty of the infection’s severity, and varied in support of all vaccines based on perceived risk/benefit ratios. Conclusion The anti-vaccine minority’s volume of comments translates to a disproportionately high representation on online boards. Public health messages should address concerns by emphasizing that immunization is always a personal choice in Canada, and that the pharmaceutical industry is strictly

    Objective: To evaluate the mental health care needs perceived as unmet by adults in Quebec who had experienced depressive and (or) anxious symptomatology (DAS) in the previous 2 years and who used primary care services, and to identify the reasons associated with different types of unmet needs for care (UNCs) and the determinants of reporting UNCs. Method: Longitudinal data from the Dialogue Project were used. The sample consisted of 1288 adults who presented a common mental disorder and who consulted a general practitioner. The Hospital Anxiety and Depression Scale was used to measure DAS, and the Perceived Need for Care Questionnaire facilitated the assessment of the different types of UNCs and their motives. Results: About 40% of the participants perceived UNCs. Psychotherapy, help to improve ability to work, as well as general information on mental health and services were the most mentioned UNCs. The main reasons associated with reporting UNCs for psychotherapy and psychosocial interventions are “couldn’t afford to pay” and “didn’t know how or where to get help,” respectively. The factors associated with mentioning UNCs (compared with met needs) are to present a high DAS or a DAS that increased during the past 12 months, to perceive oneself as poor or to not have private health insurance. Conclusions: To reduce the UNCs and, further, to reduce DAS, it is necessary to improve the availability and affordability of psychotherapy and psychosocial intervention services, and to inform users on the types of services available and how to access them.

    The Timiskaming Graben (TG) is a northwest-trending arm of the Ottawa-Bonnechere Graben and the St. Lawrence Rift System (SLRS) in eastern Canada. Together they form a 600 km long failed rift in the Canadian Shield, extending southward along the border of Ontario and Quebec to the St.Lawrence River Valley onto the Hudson Valley and Lake Champlain in the USA. The Timiskaming Graben preserves faulted outliers of Early Paleozoic limestones and has been reactivated several time during the Phanerozoic most recently during the breakup of Pangea. The 110 kilometre-long, ~100 m deep Lake Timiskaming fills the inner part of the Timiskaming Graben along the border of Ontario and Quebec. It is the postglacial successor to glacial Lake Barlow ponded against the northward-retreating Laurentide Ice Sheet some 9,000 years BP. The sedimentary record of Lake Timiskaming was established by collecting more than 1000 line kilometres of high-resolution 'chirp' seismic profiles, side scan and multibeam survey data between 2003 and 2007. These show that bathymetric relief is the product of ongoing tectonic subsidence where lateglacial Barlow glaciolacustrine and postglacial sediments are extensively deformed by closely-spaced horst and grabens. The greatest subsidence has occurred within a narrow (< 3 km) and deep (up to 209 m) central graben basin. We are able to infer the presence of hitherto unrecognized bounding and relay faults within the graben, and a 20 km long 8 m high fault scarp and sand blows produced by large postglacial earthquakes. The region is one of the most seismically active areas in eastern North America (Western Quebec Seismic Zone) with frequent moderate to large magnitude (> M5) intracratonic earthquakes. Structural activity is ongoing along the Timiskaming Graben and its lateglacial and postglacial sediment record provides the clearest evidence to date of modern intracratonic faulting anywhere in eastern North America.

  19. Social Values, Regulatory Tensions and Professional Practices with Underprivileged Populations: The Case of Quebec's Oral Healthcare System

    2011-01-01

    Objective: Dentists may experience frustration in their practice with people living on welfare, often perceiving them in a negative light. The difficulties encountered are detrimental to the patient—professional relationship and contribute to compromising access to care for this underprivileged population. In order to fully understand patient—professional interactions, we must consider the macroscopic contexts in which they occur. This paper examines the systemic influences of these interpersonal relationships to deepen our understanding of an important access-to-care determinant for people living on welfare. Methods: Two frameworks are applied to the analysis of Quebec's oral healthcare system: the social values framework and the regulatory logics framework. Results: Our assessment leads us to posit two phenomena: (1) certain negative stereotypes regarding patients living on welfare allow dentists to manage the inevitable regulatory conflicts (i.e., economic vs. professional) involved in their practice and (2) the behaviours of people living on welfare are frequently judged according to the social values embodied in the organization of Quebec's oral healthcare system, delivery and financing. Conclusion: Quebec's oral healthcare system fails to provide effective access to care for individuals living in poverty, and the government must significantly augment its involvement in this healthcare sector. Dentists should also understand the impact that systemic influences have on their rapport with people living on welfare. We argue that new orientations for the field of dental professional education should be considered.

    Nastev, M.; Savard, M. M.; Lapcevic, P.; Lefebvre, R.; Martel, R.

    This paper reports on the characterization of hydraulic properties of regional rock aquifers carried out within a groundwater resources assessment project in the St. Lawrence Lowlands of south-western Quebec. To understand the aquifer behavior at both the fracture level and at field scale, hydraulic investigations were carried out using various aquifer tests. The groundwater flow at the local scale is controlled mostly by the fracture system. Results of the constant-head injection tests show a weak decreasing trend of hydraulic conductivity with depth indicating that a major part of the groundwater flow occurs in the first meters of the rock sequence. At the regional scale, the equivalent porous media approach is applicable. The hydraulic conductivity measurements were correlated to the scale of the aquifer tests expressed with the investigated aquifer volume. A simple interpolation procedure for the hydraulic conductivity field was developed based on the distance between field measurements and the tested aquifer volumes. The regional distribution of the hydraulic conductivity for the major fractured aquifer units indicates that dolostone is the most permeable whereas sandstone and crystalline rocks are the least permeable units. Este artículo trata de la caracterización de las propiedades hidráulicas en acuíferos regionales rocosos, la cual se llevó a cabo dentro del proyecto de evaluación de los recursos de agua subterránea en St. Lawrence Lowlands al suroeste de Quebec. Para entender el comportamiento del acuífero tanto a nivel de fractura como a escala del campo, se ejecutaron investigaciones hidráulicas usando varias pruebas de acuífero. El flujo del agua subterránea a escala local está controlado principalmente por el sistema de fracturas. Los resultados de las pruebas de inyección con cabeza constante muestran una tendencia decreciente débil de la conductividad hidráulica con la profundidad, indicando que la mayor parte del flujo de agua

    The assessment model for ultraviolet radiation and risk "AMOUR" is applied to output from two chemistry-climate models (CCMs). Results from the UK Chemistry and Aerosols CCM are used to quantify the worldwide skin cancer risk avoided by the Montreal Protocol and its amendments: by the year 2030, two million cases of skin cancer have been prevented yearly, which is 14% fewer skin cancer cases per year. In the "World Avoided," excess skin cancer incidence will continue to grow dramatically after 2030. Results from the CCM E39C-A are used to estimate skin cancer risk that had already been inevitably committed once ozone depletion was recognized: excess incidence will peak mid 21st century and then recover or even super-recover at the end of the century. When compared with a "No Depletion" scenario, with ozone undepleted and cloud characteristics as in the 1960s throughout, excess incidence (extra yearly cases skin cancer per million people) of the "Full Compliance with Montreal Protocol" scenario is in the ranges: New Zealand: 100-150, Congo: -10-0, Patagonia: 20-50, Western Europe: 30-40, China: 90-120, South-West USA: 80-110, Mediterranean: 90-100 and North-East Australia: 170-200. This is up to 4% of total local incidence in the Full Compliance scenario in the peak year. PMID:22924540

    Psychiatry opens to the world at a time when the very basis of psychiatric practice, namely the asylum, is called into question. Studies appear in Quebec and Canadian journals concurrent to the introduction of new formulas for care, such as the delivery of psychiatric services in general hospitals and clinics, that allow patients to be treated outside the walls of psychiatric hospitals. In addition, postwar psychiatry takes an optimistic view toward the future of children with impairments through the creation of specialized schools and workshops.

    The 19th International Conference on Arabidopsis Research was a successful meeting attended by 815 scientists from around the world including 322 from the United States, 146 attendees from Canada, 179 from Europe, 134 from Asia, and 34 from a combination of Australia, South America, Africa and the Middle East. The scientific program was of excellent quality featuring 64 talks, including 41 from invited speakers. The Keynote Lecture, delivered by Chris Somerville (Energy Biosciences Institute/UC Berkeley) was particularly relevant to US agriculture and energy research and was titled The Development of Cellulosic Biofuels. There were also 6 community-organized workshops featuring 30 additional talks on topics including Frontiers in Plant Systems Biology, Sources and strategies for Gene Structure, Gene Function, and Metabolic Pathway annotation at TAIR and AraCyc, Advanced Bioinformatic Resources for Arabidopsis, Laser Microtechniques and Applications with Arabidopsis, Plant Proteomics- Tools, Approaches, Standards and Breakthroughs in Studying the Proteome, and Phytohormone Biosynthesis and Signal Transduction. Conference organizers arranged a special seminar by Jim Collins (head of the Directorate of Biosciences at NSF) to provide a community discussion forum regarding the future of Arabidopsis research. Approximately 575 posters were presented in topic areas including, among others, Development, Signal Transduction, Cell Walls, Non-Arabidopsis Systems, and Interactions with Biotic and Abiotic Factors. All conference abstracts and the full program are posted at The Arabidopsis Information Resource (TAIR), a publicly-accessibly website (www.arabidopsis.org/news/abstracts.jsp.) A survey completed by approximately 40% of the meeting attendees showed high satisfaction with the quality of the presentations, meeting organization and the city of Montreal.

    2011-03-01

    In this article, we describe the Quebec experience about the determinants of childhood obesity and the search for solutions, which are well adapted to the constraints of the current lifestyle. As expected, it is likely that a decrease in physical fitness and its related sedentariness as well as suboptimal food habits have contributed to the increase in overweight prevalence that was observed between 1980 and 2000. Our research experience suggests that other less suspected activity related factors have also played an important role in the occurrence of the obesity epidemic. This is particularly the case for short sleeping and demanding mental work, which are features of our modern lifestyle. Because there is no foreseeable prospect for a change in sleep and mental work habits, we argue that compensations in other factors may be necessary to prevent weight gain in this new context. We thus developed a concept of food design aiming at the maximization of the satiating properties of a food or a meal course. In this context, we were successful in the design of healthy lunch bags for students of a school located in a low socioeconomic area. Indeed, for a majority of menus, an optimal compromise seemed to be reached between nutrient composition, satiating potential, palatability, and financial accessibility. In summary, the Quebec experience reveals that childhood obesity is a complex problem that partly results from unsuspected environmental factors that deserve creative solutions to at least partly compensate for their effect.

    Canadian politicians, decision-makers, clinicians and researchers have come to agree that reforming primary care services is a key strategy for improving healthcare system performance. However, it is only more recently that real transformative initiatives have been undertaken in different Canadian provinces. One model that offers promise for improving primary care service delivery is the family medicine group (FMG) model developed in Quebec. A FMG is a group of physicians working closely with nurses in the provision of services to enrolled patients on a non-geographic basis. The objectives of this paper are to analyze the FMG's potential as a lever for improving healthcare system performance and to discuss how it could be improved. First, we briefly review the history of primary care in Quebec. Then we present the FMG model in relation to the four key healthcare system functions identified by the World Health Organization: (a) funding, (b) generating human and technological resources, (c) providing services to individuals and communities and (d) governance. Next, we discuss possible ways of advancing primary care reform, looking particularly at the family health team (FHT) model implemented in the province of Ontario. We conclude with recommendations to inspire other initiatives aimed at transforming primary care. PMID:23115575

    Projected future warming is particularly strong in the Northern high latitudes. Increases of temperatures are up to 2 to 6°C in the northern high latitudes, and up to 3 to 8°C in the North Pole area. Permafrosts (grounds with negative temperatures at least two years in a row) are present on 25 % of the northern hemisphere lands and contain high quantities of « frozen » carbon, estimated at 1400 Gt (40 % of the global terrestrial carbon). Recent studies have shown that a significant part (50%) of the first meters of the permafrost could melt within 2050, and 90 % within 2100. The aim of this study is to help understand the climate evolution in arctic areas, and more specifically of land areas covered by snow. We want to describe the ground temperature all year round even under snow cover. We hope to be able to deduce the active layer thickness evolution over the last ten years in northern Quebec. With the use of satellite data (fusion of Modis land surface temperature « LST » and AMSR-E brillance temperature « Tb », land cover …), and with the assimilation of these observations in the Canadian Landscape Surface Scheme (CLASS, CLASS-SSA) and in a simple radiative transfert model (HUT), we try to benefit from the advantages of each one of the sources in order to complete two objectives : 1- build a solid methodology in order to retrieve the land surface temperature, with and without snow cover, in taïga and toundra areas ; 2 - from those retrieved land surface temperatures, describe the ground temperature during summer as well as in winter (under snow) so that we can have a better look at the summer melt of the permafrost active layer. We have proposed a methodology that takes into account the evolution of two main input parameters of the CLASS model (air temperature and precipitations) in order to minimise the LST and Tb ouput. The proposed methodology seems to improve the results on the LST and Tb at 10 and 19 GHz in summer in a toundra environment

    Understanding the structure of the lithosphere is vital to our comprehension of plate tectonic processes. Using a seismograph network in Quebec, Canada, we attempt to identify horizontal discontinuities associated with the crust and lithospheric mantle. We also investigate systematic changes in these discontinuities across the Grenville Front and Appalachian Front, two tectonic boundaries separating the Proterozoic Grenville Province from the Archean Superior craton to the north and the Appalachian orogen to the south. Using data from long-term seismic stations, we analyzed over 3000 teleseismic earthquakes from the period 2000-2013. For each station we constructed P-to-S receiver function (RF) gathers arranged by backazimuth and epicentral distance, to identify individual phases that we can associate with seismic boundaries within the crust and upper mantle. At stations across the Superior craton, we see a strong positive phase at ~5 s with a prominent first multiple, suggesting a flat, sharp Moho boundary at ~35 km depth. A phase at ~2 s is also pervasive, likely due to an intra-crustal boundary. We do not see any evidence for a sharp lithosphere-asthenosphere boundary (LAB) in the RF data for this region. A remarkably similar structure is inferred at stations within the Grenville Province. Around the St. Lawrence River, observations from both sides of the Appalachian Front are broadly similar to each other, but systematically different from those further north. The Moho phase suggests a crustal thickness of ~40-45 km, and we do not observe any pulses that may be interpreted as Moho multiples. The crustal structure is more complex, with significant directional variation in RF signal at individual sites, and noticeable differences in RF gathers between stations separated by tens of km. This complexity likely explains the lack of coherent crustal multiples. At some stations, a negative pulse at ~15-17 s is observed, consistent with a predicted LAB depth of ~150 km

    To evaluate the relative importance of the various enteropathogens causing neonatal diarrhea in Quebec farrowing operations, observations were made on 749 diarrheic pigs from 325 outbreaks of diarrhea. They were one to 15 days of age, and were obtained alive for necropsy generally within 48 hours of the onset of diarrhea. Some pigs were from severe, explosive outbreaks of diarrhea with high morbidity and mortality rates, while others were from herds with chronic neonatal diarrhea with lower morbidity and mortality rates. A combination of bacteriological, virological and histological methods were used to study the pigs. Viruses were incriminated in 60%, bacteria in 23% and coccidia in 15.3% of the 325 diarrhea outbreaks. Transmissible gastroenteritis virus was by far the most common enteropathogen with a prevalence of 52%; rotavirus was implicated in 9.2% of the outbreaks while adenovirus was incriminated in 0.30% of the outbreaks. Enterotoxigenic Escherichia coli were involved in 22.4% of the cases while Clostridium perfringens type C was an occasional finding. Coccidia involved in our herds were identified as Isospora suis. The disease was attributed to infection with a single etiologic agent in 590 diarrheic pigs (78%) while combinations of agents were present in only 90 (12%). The age-specific occurrence of the various enteropathogens was evaluated. Transmissible gastroenteritis virus was the most common enteropathogen in all age groups. Colibacillosis was common in pigs which became diarrheic under five days of age; in this age group, the enterotoxigenic E. coli were frequently found alone, but were usually combined with other agents in older pigs. The prevalence of coccidia was high in pigs which became diarrheic between five and 15 days of age. Rotavirus infection was common in diarrheic pigs older than ten days of age. Although individual baby pigs were commonly infected with a single enteropathogen, it was very common to see more than one agent involved in

    The crystal structure of two zoned birefringent andradite garnets, ideally Ca3Fe2 3+Si3O12, from (1) Black Lake, Quebec (QC) and (2) Willsboro, New York (NY), was refined with the Rietveld method, space group , and monochromatic synchrotron high-resolution powder X-ray diffraction (HRPXRD) data. Electron probe microanalyzer results gave bulk or average compositions as follows: (1) Ca3[Fe{1.92/3+}Al0.07Mn{0.01/3+}Mg0.01]Σ2Si3O12, Adr96Grs3 and (2) {Ca2.99Mg0.01Mn{0.01/2+}}Σ3[Fe{1.52/3+}Al0.47Ti0.01]Σ2(Si2.98Al0.02)Σ3O12, Adr76Grs23. The HRPXRD data show the coexistence of two cubic phases as intergrowths in both samples. Phase-1a of the QC sample-1 has a composition of near-end-member andradite, and phase-1b is Adr91Grs9. For the NY sample-2, phase-2a is Adr76Grs23 and phase-2b is Adr59Grs39. The reduced χ2 and overall R ( F 2) Rietveld refinement values are 1.074 and 0.0268 for the QC sample, and 1.172 and 0.0333 for the NY sample. For the QC sample, the weight percentage and unit-cell parameter for phase-1a are 67.0(1) % and a = 12.06077(1) Å, and those for phase-1b are 33.0(1) % and a = 12.0535(1) Å with Δ a = 0.007 Å. For the NY sample, the corresponding values for phase-2a are 81.3(1) % and a = 12.00456(1) Å, and those for phase-2b are 18.7(1) % and a = 11.96687(1) Å with Δ a = 0.038 Å. The two cubic phases are intergrown and cause strain that arises from structural mismatch and gives rise to strain-induced birefringence. The above two samples are compared to andradite samples from Arizona and Magnet Cove.

    Background The rate of completed suicide among Inuit in Canada has been alarmingly high in recent years, and the suicide rate among Inuit in northern Quebec has increased since 1982. Our objectives were to describe the characteristics of Inuit people who died by suicide in Nunavik between 1982 and 1996, and to identify the antecedents and correlates of completed suicide. Methods We carried out a case–control study of 71 people who died by suicide between 1982 and 1996 and 71 population-based living control subjects matched for sex, community of residence and age within 1 year. Comprehensive medical charts were reviewed for data on sociodemographic characteristics, medical and psychiatric history, childhood separations and family history, and use of health care services. Results Most of the case subjects were single males aged 15 to 24 years. The two principal means of suicide were hanging (in 39 cases [54.9%]) and gunshot (in 21 cases [29.6%]). About 33% had been in contact with medical personnel in the month before their death. The case subjects were significantly more likely than the control subjects to have received a lifetime psychiatric diagnosis (one or more of depression, personality disorder or conduct disorder) (odds ratio [OR] 4.3 [95% confidence interval (CI) 1.2–15.2]) and to have had a history of psychiatric symptoms, disorder (including solvent sniffing) or treatment (OR 3.5 [95% CI 1.4–8.7]). The case subjects had experienced more severe types of nonpsychiatric illnesses and injuries than the control subjects (p = 0.04). The case subjects had more lifetime contacts with health care services than the control subjects (p = 0.01) and were more likely than the control subjects to have had contact with health care services in the year before death of the case subject (p = 0.03), even when psychiatric diagnoses were controlled for in conditional regression analysis (OR 1.02 [95% CI 1.01–1.04] and 5.0 [95% CI 1.07–23.7] respectively

    Alley cropping is an agroforestry practice whereby trees are planted in rows, thus creating alleyways within which companion crops are grown. The alley cropping systems as we call them may not only influence the local thermal energy balance by changes in airflow and solar irradiance, but also affect water uptake in plant roots and evapotranspiration. However, our understanding of the soil water balance and regulating mechanisms in alley cropping systems is very limited compared to what we know about the more common monoculture farming. Root systems of the trees are known to interact with soil water dynamics, in that they tend to grow in the direction of soil layers with a water content corresponding to a pF between 2-2.4, and conversely, water flows in the direction of decreasing hydraulic head, which, close to the root system, is in the direction of the roots when the trees absorb water by applying a suction gradient. As such, the trees in alley cropping systems either improve the resilience to drought by retaining more water in the upper soil layers, or they compete with the crops for water. With the eye on the future environmental conditions that may result from a shift in the local climate in southern Quebec, Canada, our objective is to characterize and evaluate the influence of alley cropping systems on soil water dynamics under various climate conditions. In order to evaluate the interaction between root system and soil water dynamics, we adopt an approach divided into three steps: (i) a field campaign where we monitor soil water patterns on an alley cropping site during the growing season; (ii) simulation of these soil water patterns with the HYDRUS model for two-dimensional movement of water; and (iii) the evolution of these patterns for a given scenario of climate change. Our submission focuses on the field campaign in which we used forty-five frequency domain reflectometers (FDR) along a 25-m transect perpendicular to the tree rows in order to monitor

    The Renard 2 kimberlite is located in the Otish Mountains region of Quebec, Canada and is one of the largest pipes in the Renard cluster. The cluster consists of nine kimberlite bodies and was discovered in 2001 by Ashton Mining of Canada Inc. and its joint venture partner SOQUEM Inc. Renard 2 was emplaced into Archean meta-greywacke derived migmatite, gneiss and granite of the Opinaca Subprovince of the eastern Superior Province at approximately 640.5 ± 2.8 Ma. An undetermined amount of erosion has occurred since emplacement with the present surface expression of the pipe estimated to be 0.75 ha. This kimberlite is interpreted as a steep-sided diatreme with minor irregularities in the external shape. The dominant infill is a massive volcaniclastic kimberlite (MVK) that is classified as tuffisitic kimberlite breccia (TKB) and is characterized by a high proportion of granitoid country rock xenoliths. A second dominant infill is a texturally complex, less diluted coherent kimberlite (CK) characterized locally by a transitional textures between CK and TKB. Surrounding the diatreme is a significant zone of variable width comprised of extensively brecciated country rock (+/-kimberlite) and referred to as marginal breccia. In addition to the two main rock types infilling the pipe, a number of hypabyssal kimberlite (HK) dykes and irregular shaped intrusions occur throughout the body, along the pipe contacts, within the marginal breccia and in the surrounding country rock. Geological features displayed by Renard 2 are similar to those described from Class 1 kimberlites of the Kimberley area of South Africa, the Gahcho Kué cluster of Canada and the Pimenta Bueno kimberlite field of Brazil. The economic evaluation of Renard 2 is in progress and to date has included extensive diamond and reverse circulation drilling as well as the collection of an underground bulk sample. Results from material sampled from Renard 2, including a 2449 tonne bulk sample, suggest Renard 2 has

    A significant fraction of the energy supply to eastern Canada and to the northeastern US comes from large hydropower plants located in the Canadian boreal shield. For instance, the La Grande River watershed near James Bay (Canada), hosts a hydropower complex producing nearly 40% of the overall peak load of Quebec. In this northern, remote and vast (≈100,000 km2) watershed, boreal forest is predominant, but wetlands (25% of the surface cover) are of key importance to the river's water budget. Unfortunately, little is known about how boreal wetlands affect regional hydrological processes, and hence, how they contribute to inflows to hydropower reservoirs. This study aims to gain a deeper understanding of evapotranspiration processes over boreal wetlands, based on field observations. The study site is a 60-ha bog (53.7°N, 78.2°W) located next to the Necopastic River, a tributary of the La Grande River. The peatland is of ombrotrophic type, meaning that it receives most of its water and nutrients from precipitation. The analysis relies on data collected by a flux tower during a field campaign throughout summer 2012., as well as detailed measurements of the water budget in this sub-watershed. One key finding is that the atmosphere is neutrally-stratified for more than 60% of the summer. The impact of this unusual feature of the atmospheric boundary layer on water vapor fluxes is carefully analyzed. As expected, eddy covariance evapotranspiration data compared well with classical formulas (Priestley-Taylor, Penman, Penman-Monteith, FAO), particularly with Priestley-Taylor. Given nearly all these formulations command direct measurements or estimations of net radiation, and that the cost of net radiometers is prohibitive, we tested the less frequently used profile method, which simply requires one or two additional measurement levels of wind speed, temperature and humidity. The latter method led to promising results, especially considering its ease of implementation

    Noble gases, in particular 3He/4He (R) ratios, were measured together with tritium activity in groundwater from eskers and moraines of the Abitibi-Temiscamingue region of northwestern Quebec (eastern Canada). These high-latitude glaciofluvial landforms contain precious freshwater resources that need to be quantified. Here we provide estimates of residence time for groundwater in glaciofluvial sediments forming the Saint-Mathieu-Berry (SMB) and Barraute eskers, the Harricana moraine and in the underlying fractured bedrock aquifer. The 3He/4He ratios range from 0.224 ± 0.012 to 1.849 ± 0.036Ra, where Ra is the atmospheric 3He/4He ratio (1.386 × 10-6). These results suggest the occurrence of 3He produced by decay of tritium and terrigenic 4He produced by decay of U and Th. Calculated 3H/3He apparent ages of groundwater from the SMB esker and the Harricana moraine range from 6.6 ± 1.1 a to 32 ± 7.4 a. Terrigenic 4He (4Heterr) was found in the deeper wells of the SMB esker and in the wells tapping water from the deeper fractured aquifer located below the eskers and moraines and confined by postglacial clays. The amount of 4Heterr ranges from 3.4 × 10-9 to 2.2 × 10-6 cm3STP g-1 and shows a clear gradient with depth, suggesting addition of a 4Heterr flux entering the bottom of the eskers. Modeled 4Heterr fluxes range from 2.0 × 10-8 cm3STP cm-2 yr-1 at the Harricana moraine to 6.6 × 10-7 cm3STP cm-2 yr-1 in the southern section of the SMB esker. Calculated fluxes are highly variable and 5-165 times lower than the helium continental crustal flux, suggesting local helium sources, with helium being driven upward through preferential pathways such as local faults. Maximum U-Th/4He ages obtained for the groundwater in the fractured bedrock range from 1473 ± 300 a to 137 ± 28 ka, suggesting the occurrence of several generations of fossil meltwater trapped under the clay plain after the last two glaciations.

    Introduction Trans youths are more likely to experience negative social and parental reactions suggesting reprehension, from disapproving looks to physical violence. While victimization increases the likelihood of poor mental health outcomes, little is known about potential mediating factors between mental health and victimization. Self-esteem is one of the factors that may mediate the impact of homophobic victimization on mental health. Yet, data on trans youths are scarce.Objectives The objectives of this paper are: 1) to compare trans youths to cisgender heterosexual male and female youths regarding two different forms of victimization (victimization based on gender nonconformity and parental verbal abuse), self-esteem, and psychological distress, as well as 2) to test a path model of the impact of these two forms of victimization on self-esteem and psychological distress.Methods Data for this study are drawn from the Quebec Youths' Romantic Relationships survey. Data were collected among youth aged 14 to 22 years old recruited either in schools or online. Thirty-seven participants endorsed being trans or questioning their gender identity. They were paired to 74 cisgender heterosexual youths (37 male and 37 female) using propensity scores based on socio-demographic characteristics.Results Results showed that verbal parental abuse and victimization based on gender nonconformity were more prevalent among trans participants. Parental verbal abuse and victimization based on gender nonconformity were both directly and negatively associated with self-esteem (explained variance: 36%). Sexual status explains 19.6% of the variance of parental victimization and 50.6% of the variance of victimization on the basis of gender nonconformity. A higher self-esteem was associated with decreased psychological distress (explained variance: 66.9%). Moreover, parental verbal abuse was also directly associated with higher psychological distress. Although there was no direct

    Nearly 2 billion people use groundwater and in Canada it is the potable water supply for about 30% of the population. Groundwater is also used in industrial and agricultural applications, and contributes to important hydrological habitats for various species. Limited research has been conducted to determine the potential impacts of climate change on groundwater. Local studies are crucial to better understand how, for example, increased duration and frequency of storms or drought periods may affect groundwater dependent ecosystems in order to anticipate and mitigate the impacts. Thus, the aim of this research is to explore the effects of climate change on a groundwater-surface water interacting system that supports a fragile ecosystem. This research is used to inform ecological conservation measures. The research site is the 17500 ha Covey Hill Natural Laboratory, which is located on the Quebec, Canada and New York State, USA border in the Chateauguay River watershed. At various locations within the Natural Laboratory there is continuous monitoring of groundwater levels and river flows. Covey Hill is an important recharge zone for the regional aquifer and provides habitat for endangered salamanders in discharge zones. Two hydrogeological models were constructed to represent flow at the site. First, a three-dimensional, finite difference model was developed using MODFLOW software to simulate overall groundwater flow at the research site. Second, a smaller-scale, discrete fracture, transient, three-dimensional, finite difference, integrated model was developed using HydroGeoSphere software to represent in better detail flow from bedrock springs that occur at mid-slope and provide the habitat for endangered salamanders. The models were used to: 1) observe groundwater flow under current climate conditions; 2) quantify water dynamics in response to climate change using 10 scenarios from the Canadian Regional Climate Model (for 1971-2000 and 2041-2070 time periods); and 3

    Game meat from animals killed by lead ammunition may expose consumers to lead. We assessed the risk related to lead intake from meat consumption of white-tailed deer and moose killed by lead ammunition and documented the perception of hunters and butchers regarding this potential contamination. Information on cervid meat consumption and risk perception were collected using a mailed self-administrated questionnaire which was addressed to a random sample of Quebec hunters. In parallel, 72 samples of white-tailed deer (n = 35) and moose (n = 37) meats were collected from voluntary hunters and analysed for lead content using inductively coupled plasma-mass spectrometry. A risk assessment for people consuming lead shot game meat was performed using Monte Carlo simulations. Mean lead levels in white-tailed deer and moose killed by lead ammunition were 0.28 and 0.17 mg kg(-1) respectively. Risk assessment based on declared cervid meat consumption revealed that 1.7% of the surveyed hunters would exceed the dose associated with a 1 mmHg increase in systolic blood pressure (SBP). For consumers of moose meat once, twice or three times a week, simulations predicted that 0.5%, 0.9% and 1.5% of adults would be exposed to a dose associated with a 1 mmHg increase in SBP, whereas 0.9%, 1.9% and 3.3% of children would be exposed to a dose associated with 1 point intelligence quotient (IQ) decrease, respectively. For consumers of deer meat once, twice or three times a week, the proportions were 1.6%, 2.9% and 4% for adults and 2.9%, 5.8% and 7.7% for children, respectively. The consumption of meat from cervids killed with lead ammunition may increase lead exposure and its associated health risks. It would be important to inform the population, particularly hunters, about this potential risk and promote the use of lead-free ammunition. PMID:26161681
