AstroMcGill was founded in 2011 by an enthusiastic group of undergraduate students, graduate students and post-doctoral fellows. It serves as the education and public outreach (EPO) branch of the astronomy group within the Physics Department at McGill University in Montreal, Quebec. Over the last five years, AstroMcGill has grown from organizing sporadic visits in a couple primary schools to running a successful inquiry-based outreach programme for grade 4-6 students, the McGill Space Explorers. During the same time span, the attendance at public AstroNight lectures ramped up from attracting a few dozen people to over 500 people each month. We will highlight the recent successes of the programme and our best guesses for the reasons behind this success. We will also discuss the challenges of working in a bilingual city as we juggle our majority anglophone volunteers, a mandatory french science curriculum for primary school children and the (somewhat) overlapping English- and French-speaking communities in the city.

2012-01-01

The McGill consensus statement on overdentures (14) was published following a symposium held at McGill University in Montreal, Canada in 2002. A panel of relevant experts in the field stated that: The evidence currently available suggests that the restoration of the edentulous mandible with a conventional denture is no longer the most appropriate first choice prosthodontic treatment. There is now overwhelming evidence that a two-implant overdenture should become the first choice of treatment for the edentulous mandible (14). In 2009, a further consensus statement was released as a support and follow-up to the McGill consensus statement. This report was jointly created by members of the BSSPD (British Society for the Study of Prosthetic Dentistry) Council and the panel of presenters at the BSSPD conference in York, UK in April 2009 (15). This report also highlighted that since the McGill statement in 2002, uptake by dentists of implant technology for complete denture wearers has been slow. The York statement concluded that 'a substantial body of evidence is now available demonstrating that patients' satisfaction and quality of life with ISOD mandibular overdentures is significantly greater than for conventional dentures. Much of this data comes from randomised controlled trials (15). Whilst it is accepted that the two-implant overdenture is not the gold standard of implant therapy it is the minimum standard that should be sufficient for most people, taking into account performance, patient satisfaction, cost and clinical time.

Near-infrared (NIR) technology appears promising as a non-invasive clinical technique for breast cancer screening and diagnosis. The technology capitalizes on the relative transparency of human tissue in this spectral range and its sensitivity to the main components of the breast:; water, lipid and hemoglobin. In this work we present initial results obtained using the SoftScan® breast-imaging system developed by ART, Advanced Research Technologies inc., Montreal. This platform consists of a 4-wavelength time-resolved scanning system used to quantify non-invasively the local functional state of breast tissue. The different aspects of the system used to retrieve 3D optical contrast will be presented. Furthermore, preliminary data obtained from a prospective study conducted at The Royal Victoria Hospital of the McGill University Health Center in Montreal will be discussed. Analysis of the data gathered by SoftScan® demonstrated the potential of the technology in discriminating between healthy and diseased tissue.

Phil Wallace and Theoretical Physics at McGill in the 1950's: A Personal Perspective

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jackson, John David

In 1946 Philip (Phil) Russell Wallace joined the Mathematics Department of McGill University as an Associate Professor of Applied Mathematics, apparently because A. H. S. Gillson, Dean of Arts and Science, wanted theoretical physicists to be in the Mathematics Department. He came with the dream of creating a theoretical physics group at McGill. By the spring of 1949, Phil was authorized to recruit two junior faculty in Mathematics. He hired Theodore (Ted) F. Morris from U. Toronto, who joined in September 1949, and me, who came in January 1950. The group had begun. Phil Wallace was born in Toronto inmore » 1915 and grew up there. He entered the University of Toronto in 1933, earned a B.A. in mathematics in 1937, a M.A. in 1938, and a Ph.D. in applied mathematics in 1940 under Leopold Infeld. His Ph.D. thesis in general relativity was entitled 'On the relativistic equations of motion in electromagnetic theory.' In 1940 World War II had engulfed Europe and was having its effect on Canada, but the US was still at peace. L. J. Synge, Head of the Applied Mathematics Department at Toronto, told Wallace that people such as he would be needed in war work, but things were not ready quite yet. Hold yourself ready. Phil took a two-year position as lecturer in mathematics at the University of Cincinnati (1940-42); in the fall of 1942 he became a lecturer in mathematics at M.I.T. It was from there that he was recruited by Synge to join the war effort from 1943 to 1946 at N.R.C.'s Montreal Laboratory, the genesis of the Canadian Atomic Energy Project. Phil has described those heady wartime years in these pages. Much of the effort of the theoretical physicists was on nuclear reactor theory and the properties of relevant materials, such as graphite, under long and intense neutron bombardment. In late 1945 Phil was sent for four months to Bristol to learn about the properties of graphite from the esteemed N. F. Mott. This exposure led Phil to a life-long interest in graphite and in condensed matter physics in general. After the war, the group of Montreal Lab theorists dissolved - some had already left for Los Alamos; some went to Chalk River; Volkoff returned to UBC to foster theoretical physics as part of physics in the West; Wallace to do the same in the East. But the path at McGill was not smooth. As a singular anomaly in a pure math department, Phil was tucked away in the corner of some engineering building, remote from the bulk of the mathematicians. And there was no welcoming mat from Physics. As Wallace remarks, 'I took a post at McGill, not surprisingly in the department of Mathematics. Certain complications of academic politics followed, such as jurisdictional disputes over course assignments. Theoretical physicists were treated more or less as foreigners or rivals by at least a segment of the physics department.' 'Why was that?' McGill's attitude about theoretical physics was colored for fifty years by the lingering influence of Ernest Rutherford, who was a faculty member from 1898 to 1907. In his essay about the beginnings of theoretical physics in Canada, Wallace quotes examples of Rutherford's views about theoretical physics. In short, theoretical physics is applied mathematics and has no place in a department devoted to the study of natural phenomena. Because of his eminence and connection to McGill, numerous physics graduates went to the 'Mecca' of Manchester then Cambridge to do a Ph.D. with the great man. Some then returned to the McGill Physics faculty to teach and perpetuate the Rutherfordian view of theory. Although the theoretical physics group at McGill in the 1950s had no official standing and no statutory leader, Phil Wallace was that leader and builder of the group. An inspiration to students and junior colleagues alike, he protected and nurtured us in the sometimes difficult circumstances of citizens without a country.« less

The technical challenges of endoscopic sinus surgery (ESS) and the high risk of complications support the development of alternative modalities to train residents in these procedures. Virtual reality simulation is becoming a useful tool for training the skills necessary for minimally invasive surgery; however, there are currently no ESS virtual reality simulators available with valid evidence supporting their use in resident education. Our aim was to develop a new rhinology simulator, as well as to define potential performance metrics for trainee assessment. The McGill simulator for endoscopic sinus surgery (MSESS), a new sinus surgery virtual reality simulator with haptic feedback, was developed (a collaboration between the McGill University Department of Otolaryngology-Head and Neck Surgery, the Montreal Neurologic Institute Simulation Lab, and the National Research Council of Canada). A panel of experts in education, performance assessment, rhinology, and skull base surgery convened to identify core technical abilities that would need to be taught by the simulator, as well as performance metrics to be developed and captured. The MSESS allows the user to perform basic sinus surgery skills, such as an ethmoidectomy and sphenoidotomy, through the use of endoscopic tools in a virtual nasal model. The performance metrics were developed by an expert panel and include measurements of safety, quality, and efficiency of the procedure. The MSESS incorporates novel technological advancements to create a realistic platform for trainees. To our knowledge, this is the first simulator to combine novel tools such as the endonasal wash and elaborate anatomic deformity with advanced performance metrics for ESS.

Respiratory medicine and research at McGill University: A historical perspective

PubMed Central

Martin, James G; Schwartzman, Kevin

2015-01-01

The history of respiratory medicine and research at McGill University (Montreal, Quebec) is tightly linked with the growth of academic medicine within its teaching hospitals. Dr Jonathan Meakins, a McGill medical graduate, was recruited to the Royal Victoria Hospital in 1924; as McGill’s first full-time clinical professor and Physician-in-Chief at the Royal Victoria Hospital. His focus on respiratory medicine led to the publication of his first book, Respiratory Function in Disease, in 1925. Meakins moved clinical laboratories from the Department of Pathology and placed them within the hospital. As such, he was responsible for the development of hospital-based research. Dr Ronald Christie was recruited as a postdoctoral fellow by Meakins in the early 1930s. After his fellowship, he returned to Britain but came back to McGill from St Bartholomew’s Hospital (London, United Kingdom) to become Chair of the Department of Medicine in 1955; he occupied the post for 10 years. He published extensively on the mechanical properties of the lung in common diseases such as emphysema and heart failure. Dr David Bates was among Dr Christie’s notable recruits; Bates in turn, recruited Drs Maurice McGregor, Margaret Becklake, William Thurlbeck, Joseph Milic-Emili, Nicholas Anthonisen, Charles Bryan and Peter Macklem. Bates published extensively in the area of respiratory physiology and, with Macklem and Christie, coauthored the book Respiratory Function in Disease, which integrated physiology into the analysis of disease. Dr JA Peter Paré joined the attending staff of the Royal Victoria Hospital and the Royal Edward Laurentian Hospital in 1949. A consummate clinician and teacher, he worked closely with Dr Robert Fraser, the Chair of Radiology, to write the reference text Diagnosis of Diseases of the Chest. This was a sentinel contribution in its focus on radiographic findings as the foundation for a systematic approach to diagnosis, and the correlation of these findings with pathological and clinical observations. Dr Margaret Becklake immigrated to Montreal from South Africa in 1957. Her research focused on occupational lung disease. She established the respiratory epidemiology research unit at McGill. She was renowned for her insistence on the importance of a clearly stated, relevant research question and for her clarity and insight. Dr William Thurlbeck, another South African, had developed an interest in emphysema and chronic bronchitis and applied a structure-function approach in collaboration with Peter Macklem and other respirologists. As chief of the Royal Victoria autopsy service, he used pathological specimens to develop a semiquantitative grading system of gross emphysema severity. He promoted the use of morphometry to quantify structural abnormalities. Dr James Hogg studied the functional consequences of pathological processes for lung function during his PhD studies under the joint supervision of Drs Macklem and Thurlbeck. His contributions to understanding the structural basis for chronic obstructive pulmonary disease (COPD) are numerous, reflecting his transdisciplinary knowledge of respiratory pathology and physiology. He trained other outstanding investigators such as Peter Paré Jr, with whom he founded the Pulmonary Research Laboratory in St Paul’s Hospital in Vancouver (British Columbia) in 1977. A signal event in the evolution of respiratory research at McGill was the construction of the Meakins-Christie Laboratories in 1972. These laboratories were directed by Dr Peter Macklem, a trainee of Dr Becklake’s. The research within the laboratory initially focused on respiratory mechanics, gas distribution within the lung and the contribution of airways of different sizes to the overall mechanical behaviour of the lungs. The effects of cigarette smoking on lung dysfunction, mechanisms of possible loss of lung elastic recoil in asthma and control of bronchomotor tone were all additional areas of active investigation. Dr Macklem pioneered the study of the physiological consequences of small airway pathology. Dr Joseph Milic-Emili succeeded Dr Macklem as director of the Meakins-Christie Laboratories in 1979. Milic-Emili was renowned for his work on ventilation distribution and the assessment of pleural pressure. He led the development of convenient tools for the assessment of respiratory drive. He clarified the physiological basis for carbon dioxide retention in patients with COPD placed on high inspired oxygen concentrations. Another area that captured many investigators’ attention in the 1980s was the notion of respiratory failure as a consequence of respiratory muscle fatigue. Dr Charalambos (‘Charis’) Roussos made seminal contributions in this field. These studies triggered a long-lasting interest in respiratory muscle training, in rehabilitation, and in noninvasive mechanical ventilation for acute and chronic respiratory failure. Dr Ludwig Engel obtained his PhD under the supervision of Peter Macklem and established himself in the area of ventilation distribution in health and in bronchoconstriction and the mechanics of breathing in asthma; he trained many investigators including one of the authors, Dr Jim Martin, who succeeded Milic-Emili as director of the Meakins Christie Laboratories from 1993 to 2008. Dr Martin developed small animal models of allergic asthma, and adopted a recruitment strategy that diversified the research programs at the Meakins Christie Laboratories. Dr Manuel Cosio built on earlier work with Macklem and Hogg in his development of key structure-function studies of COPD. He was instrumental in recruiting a new generation of young investigators with interests in sleep medicine and neuromuscular diseases. The 1970s and 1980s also witnessed the emergence of a topnotch respiratory division at the Montreal General Hospital, in large part reflecting the leadership of Dr Neil Colman, later a lead author of the revised Fraser and Paré textbook. At the Montreal General, areas of particular clinical strength and investigation included asthma, occupational and immunological lung diseases. In 1989, the Meakins Christie Laboratories relocated to its current site on Rue St Urbain, adjacent to the Montreal Chest Institute. Dr Qutayba Hamid, on faculty at the Brompton Hospital, joined the Meakins-Christie Labs in 1994. In addition to an outstanding career in the area of the immunopathology of human asthma, he broadened the array of techniques routinely applied at the labs and has ably led the Meakins-Christie Labs from 2008 to the present. The Meakins Christie Laboratories have had a remarkable track record that continues to this day. The basis for its enduring success is not immediately clear but it has almost certainly been linked to the balance of MD and PhD scientists that brought perspective and rigour. The diverse disciplines and research programs also facilitated adaptation to changing external research priorities. The late 1990s and the early 21st century also saw the flourishing of the Respiratory Epidemiology Unit, under the leadership of Drs Pierre Ernst, Dick Menzies and Jean Bourbeau. It moved from McGill University to the Montreal Chest Institute in 2004. This paved the way for expanded clinical and translational research programs in COPD, tuberculosis, asthma, respiratory sleep disorders and other pulmonary diseases. The faculty now comprises respiratory clinician-researchers and PhD scientists with expertise in epidemiological methods and biostatistics. Respiratory physiology and medicine at McGill benefitted from a strong start through the influence of Meakins and Christie, and a tight linkage between clinical observation and physiological research. The subsequent recruitment of talented and creative faculty members with absolute dedication to academic medicine continued the legacy. No matter how significant the scientific contributions of the individuals themselves, their most important impact resulted from the training of a large cohort of other gifted physicians and graduate students. Some of these are further described in the accompanying full-length online article. PMID:25664457

Atypical antipsychotics have been associated with weight gain. This study examines the efficacy of adjunctive topiramate in patients with schizophrenia and schizoaffective disorder with antipsychotic-induced weight gain. A 2-year retrospective case analysis was performed in all 300 patients of the outpatient Special Follow-up Clinic for chronic schizophrenia and related psychoses at the Allan Memorial Institute, McGill University Health Centre (Montreal, Canada), a tertiary care University teaching hospital. 10 patients met study inclusion criteria. Mean daily topiramate dose was 197.5 mg (A+/-77) (range, 125-400 mg). Topiramate produced continued weight loss throughout the study duration without tolerance. Patients treated for 6 months and more had significantly higher Body Mass Index (BMI) differences than those treated for shorter durations (BMI-d6 months=-4.7A+/-2.4; BMI-d2 months=-3.2A+/-2.3; P=0.015). BMI changes were similar across genders. This study supports topiramate use to target weight loss in stable overweight schizophrenic patients as a potential therapy that requires further investigation.

On making cuts for magnetic scalar potentials in multiply connected regions

NASA Astrophysics Data System (ADS)

Kotiuga, P. R.

1987-04-01

The problem of making cuts is of importance to scalar potential formulations of three-dimensional eddy current problems. Its heuristic solution has been known for a century [J. C. Maxwell, A Treatise on Electricity and Magnetism, 3rd ed. (Clarendon, Oxford, 1981), Chap. 1, Article 20] and in the last decade, with the use of finite element methods, a restricted combinatorial variant has been proposed and solved [M. L. Brown, Int. J. Numer. Methods Eng. 20, 665 (1984)]. This problem, in its full generality, has never received a rigorous mathematical formulation. This paper presents such a formulation and outlines a rigorous proof of existence. The technique used in the proof expose the incredible intricacy of the general problem and the restrictive assumptions of Brown [Int. J. Numer. Methods Eng. 20, 665 (1984)]. Finally, the results make rigorous Kotiuga's (Ph. D. Thesis, McGill University, Montreal, 1984) heuristic interpretation of cuts and duality theorems via intersection matrices.

A bibliometric analysis of digestive health research in Canada.

PubMed

Tuitt, Desiree; Knight, Frank; Lipman, Tara

2011-11-01

Measurement of the impact and influence of medical⁄scientific journals, and of individual researchers has become more widely practiced in recent decades. This is driven, in part, by the increased availability of data regarding citations of research articles, and by increased competition for research funding. Digestive disease research has been identified as a particularly strong discipline in Canada. The authors collected quantitative data on the impact and influence of Canadian digestive health research. The present study involved an analysis of the research impact (Hirsch factor) and research influence (Influence factor) of 106 digestive health researchers in Canada. Rankings of the top 25 researchers on the basis of the two metrics were dominated by the larger research groups at the University of Toronto (Toronto, Ontario), McMaster University (Hamilton, Ontario), and the Universities of Calgary (Calgary, Alberta) and Alberta (Edmonton, Alberta), but with representation by other research groups at the Universities of Manitoba (Winnipeg, Manitoba), Western Ontario (London, Ontario) and McGill University (Montreal, Quebec). Female and male researchers had similar scores for the two metrics, as did basic scientists versus clinical investigators. Strategic recruitment, particularly of established investigators, can have a major impact on the ranking of research groups. Comparing these metrics over different time frames can provide insights into the vulnerabilities and strengths of research groups.

EDITORIAL: International Workshop on Monte Carlo Techniques in Radiotherapy Delivery and Verification

Verhaegen, Frank; Seuntjens, Jan

2008-03-01

Monte Carlo particle transport techniques offer exciting tools for radiotherapy research, where they play an increasingly important role. Topics of research related to clinical applications range from treatment planning, motion and registration studies, brachytherapy, verification imaging and dosimetry. The International Workshop on Monte Carlo Techniques in Radiotherapy Delivery and Verification took place in a hotel in Montreal in French Canada, from 29 May-1 June 2007, and was the third workshop to be held on a related topic, which now seems to have become a tri-annual event. About one hundred workers from many different countries participated in the four-day meeting. Seventeen experts in the field were invited to review topics and present their latest work. About half of the audience was made up by young graduate students. In a very full program, 57 papers were presented and 10 posters were on display during most of the meeting. On the evening of the third day a boat trip around the island of Montreal allowed participants to enjoy the city views, and to sample the local cuisine. The topics covered at the workshop included the latest developments in the most popular Monte Carlo transport algorithms, fast Monte Carlo, statistical issues, source modeling, MC treatment planning, modeling of imaging devices for treatment verification, registration and deformation of images and a sizeable number of contributions on brachytherapy. In this volume you will find 27 short papers resulting from the workshop on a variety of topics, some of them on very new stuff such as graphics processing units for fast computing, PET modeling, dual-energy CT, calculations in dynamic phantoms, tomotherapy devices, . . . .

OBJECTIVE To demonstrate that senior surgical residents would benefit from focused training by professionals with management expertise. Although managerial skills are recognized as necessary for the successful establishment of a surgical practice, they are not often emphasized in traditional surgical residency curricula. DESIGN Senior residents from all surgical subspecialties at McGill University were invited to participate in a 1-day management seminar. Precourse questionnaires aimed at evaluating the residents' perceptions of their own managerial knowledge and preparedness were circulated. The seminar was then given in the form of interactive lectures and case-based discussions. The questionnaires were readministered at the end of the course, along with an evaluation form. Precourse and postcourse data were compared using the Freeman-Halton extension of the Fisher exact test to determine statistical significance (P < .05). SETTING McGill University Health Centre in Montreal, Quebec, Canada. PARTICIPANTS A total of 43 senior residents. RESULTS Before the course, the majority of residents (27 of 43 [63%]) thought that management instruction only happened "from time to time" in their respective programs. After the course, 15 residents (35%) felt that management topics were "well addressed," and 19 (44%) felt that management topics have been "very well addressed" (P < .01). Residents noted a significant improvement in their ability to perform the following skills after the course: giving feedback, delegating duties, coping with stress, effective learning, and effective teaching. On the ensemble of all managerial skills combined, 26 residents (60%) rated their performance as "good" or "excellent" after the course vs only 21 (49%) before the course (P = .02). Residents also noted a statistically significant improvement in their ability to perform the managerial duties necessary for the establishment of a surgical practice. CONCLUSIONS Surgical residency programs have the responsibility of preparing their residents for leadership and managerial roles in their future careers. An annual seminar serves as a starting point that could be built on for incorporating formal management training in surgical residency curricula.

The McGill Group in Medical Genetics was formed in 1972, supported by the Medical Research Council and successor Canadian Institutes for Health Research until September 2009, making it the longest active biomedical research group in the history of Canada. We document the history of the McGill Group and situate its research within a broader history of medical genetics. Drawing on original oral histories with the Group's members, surviving documents, and archival materials, we explore how the Group's development was structured around epistemological trends in medical genetics, policy choices made by research agencies, and the development of genetics at McGill University and its hospitals.

EDITORIAL: International Workshop on Current Topics in Monte Carlo Treatment Planning

2005-03-01

The use of Monte Carlo particle transport simulations in radiotherapy was pioneered in the early nineteen-seventies, but it was not until the eighties that they gained recognition as an essential research tool for radiation dosimetry, health physics and later on for radiation therapy treatment planning. Since the mid-nineties, there has been a boom in the number of workers using MC techniques in radiotherapy, and the quantity of papers published on the subject. Research and applications of MC techniques in radiotherapy span a very wide range from fundamental studies of cross sections and development of particle transport algorithms, to clinical evaluation of treatment plans for a variety of radiotherapy modalities. The International Workshop on Current Topics in Monte Carlo Treatment Planning took place at Montreal General Hospital, which is part of McGill University, halfway up Mount Royal on Montreal Island. It was held from 3-5 May, 2004, right after the freezing winter has lost its grip on Canada. About 120 workers attended the Workshop, representing 18 countries. Most of the pioneers in the field were present but also a large group of young scientists. In a very full programme, 41 long papers were presented (of which 12 were invited) and 20 posters were on display during the whole meeting. The topics covered included the latest developments in MC algorithms, statistical issues, source modelling and MC treatment planning for photon, electron and proton treatments. The final day was entirely devoted to clinical implementation issues. Monte Carlo radiotherapy treatment planning has only now made a slow entrée in the clinical environment, taking considerably longer than envisaged ten years ago. Of the twenty-five papers in this dedicated special issue, about a quarter deal with this topic, with probably many more studies to follow in the near future. If anything, we hope the Workshop served as an accelerator for more clinical evaluation of MC applications. The remainder of the papers in this issue demonstrate that there is still plenty of work to be undertaken on other topics such as source modelling, calculation speed, data analysis, and development of user-friendly applications. We acknowledge the financial support of the National Cancer Institute of Canada, the Institute of Cancer Research of the Canadian Institutes of Health Research, the Research Grants Office and the Post Graduate Student Society of McGill University, and the Institute of Physics Publishing (IOPP). A final word of thanks goes out to all of those who contributed to the successful Workshop: our local medical physics students and staff, the many colleagues who acted as guest associate editors for the reviewing process, the IOPP staff, and the authors who generated new and exciting work.

The life, achievements and legacy of a great Canadian investigator: Professor Boris Petrovich Babkin (1877-1950).

PubMed

Beck, Ivan T

2006-09-01

The present paper reviews the life and achievements of Professor Boris Petrovich Babkin (MD DSc LLD). History is only worth writing about if it teaches us about the future; therefore, this historical review concludes by describing what today's and future gastrointestinal physiologists could learn from Dr Babkin's life. Dr Babkin was born in Russia in 1877. He graduated with an MD degree from the Military Medical Academy in St Petersburg, Russia, in 1904. Not being attracted to clinical practice, and after some hesitation concerning whether he would continue in history or basic science of medicine, he entered the laboratory of Professor Ivan Petrovich Pavlov. Although he maintained an interest in history, in Pavlov's exciting environment he became fully committed to physiology of the gastrointestinal system. He advanced quickly in Russia and was Professor of Physiology at the University of Odessa. In 1922, he was critical of the Bolshevik revolution, and after a short imprisonment, he was ordered to leave Russia. He was invited with his family by Professor EH Starling (the discoverer of secretin) to his department at University College, London, England. Two years later, he was offered a professorship in Canada at Dalhousie University, Halifax, Nova Scotia. After contributing there for four years, he joined McGill University, Montreal, Quebec, in 1928 as Research Professor. He remained there for the rest of his career. Between 1940 and 1941, he chaired the Department, and following retirement, he remained as Research Professor. At the invitation of the world-famous neurosurgeon, Wilder Penfield, Dr Babkin continued as Research Fellow in the Department of Neurosurgery until his death in 1950 at age 73. His major achievements were related to establishing the concept of brain-gut-brain interaction and the influence of this on motility, as well as on interface of multiple different cells, nerves and hormones on secretory function. He had a major role in the rediscovery of gastrin. He established a famous school of gastrointestinal physiologists at McGill University. He supported his trainees and helped them establish their careers. He received many honors: a DSc in London, England, and an LLD from Dalhousie University. Most importantly, he was the recipient of the Friedenwald Medal of the American Gastroenterological Association for lifelong contributions to the field. Dr Babkin taught us his philosophical aspect of approaching physiology, his devotion to his disciples and his overall kindness. Most importantly, he has proven that one can achieve international recognition by publishing mainly in Canadian journals. He is an example to follow.

Harold Griffith Memorial Lecture. The Griffith legacy.

Sykes, K

1993-04-01

1992 was the anniversary of Crawford Long's use of ether in 1842, and Griffith and Johnson's introduction of Intocostrin into anaesthetic practice in 1942. Harold Randall Griffith was born in Montreal in 1894 and died in 1985. He interrupted his medical studies to serve in the first world war and was awarded the Military Medal for gallantry at the battle of Vimy Ridge. Griffith qualified from McGill University in 1922. After spending a year studying homoeopathic medicine, he joined his father's general practice and became the anaesthetist to the Homoeopathic Hospital in Montreal. He succeeded his father as Medical Director of the hospital (now renamed the Queen Elizabeth Hospital) in 1936 and retired in 1966. Griffith was a superb clinical anaesthetist. He was an early advocate of detailed anaesthetic records, and was responsible for the introduction of both ethylene and cyclopropane into Canadian practice, later teaching himself to intubate under these two agents. Griffith was one of the first to be concerned with standards of patient care. He introduced postoperative recovery and intensive care units into Canadian practice and played a major role in postgraduate teaching. He was unstinting in his support of organisations designed to further the progress of anaesthesia and was the first President of the Canadian Anaesthetist's Society. He was one of those responsible for inaugurating the World Federation of Societies of Anaesthesiology and was President of the First World Congress of Anaesthesiology in 1955. It is remarkable that the introduction of curare into anaesthetic practice was delayed until 1942, since curare had been used in anaesthesia some 30 years previously. However, it was probably Griffith's confidence in his own clinical abilities which enabled him to seize the opportunity when it was offered.

To study the rate of postoperative hypocalcemia following completion thyroidectomy (CT), in comparison with the hypocalcemia rate following total thyroidectomy (TT). A retrospective study, performed at the McGill University Thyroid Cancer Center, Montreal, Quebec, Canada, from 2007 to 2012. Medical records of adult patients undergoing CT and TT operated by a single surgeon were reviewed. Data were extracted for demographics, postoperative calcium levels, surgical logs, and final surgical pathology. Hypocalcemia was defined as corrected serum calcium level ≤ 1.90 mmol/L, with concurrent serum parathyroid hormone <8 ng/L, and/or any signs or symptoms of hypocalcemia. There were 68 CTs and 146 TTs. Transient hypocalcemia occurred in 1 of 68 (1.5%) and 18 of 146 (12.5%) patients in the CT and TT groups, respectively. The rate of hypocalcemia was significantly lower in the CT compared with the TT group (P = .02). In both groups, there were no cases of permanent hypocalcemia. The risk of transient of hypocalcemia in patients undergoing CT is significantly lower than the rate of hypocalcemia in patients undergoing TT. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

2014-01-01

Background. The aim of this study was to compare acute outcome between men and women after sustaining a traumatic brain injury (TBI). Methods. A total of 5,642 patients admitted to the Traumatic Brain Injury Program of the McGill University Health Centre-Montreal General Hospital between 2000 and 2011 and diagnosed with a TBI were included in the study. The overall percentage of women with TBI was 30.6% (n = 1728). Outcome measures included the length of stay (LOS), the Extended Glasgow Outcome Scale (GOSE), the functional independence measure instrument (FIM), discharge destination, and mortality rate. Results. LOS, GOSE, the FIM ratings, and discharge destination did not show significant differences between genders once controlling for several confounding variables and running the appropriate diagnostic tests (P < 0.05). However, women had less chance of dying during their acute care hospitalization than men of the same age, with the same TBI severity and following the same mechanism of injury. Although gender was a statistically significant predictor, its contribution in explaining variation in mortality was small. Conclusion. More research is needed to better understand gender differences in mortality; as to date, the research findings remain inconclusive. PMID:27355011

Current selection methods for neurosurgical residents fail to include objective measurements of bimanual psychomotor performance. Advancements in computer-based simulation provide opportunities to assess cognitive and psychomotor skills in surgically naive populations during complex simulated neurosurgical tasks in risk-free environments. This pilot study was designed to answer 3 questions: (1) What are the differences in bimanual psychomotor performance among neurosurgical residency applicants using NeuroTouch? (2) Are there exceptionally skilled medical students in the applicant cohort? and (3) Is there an influence of previous surgical exposure on surgical performance? Participants were instructed to remove 3 simulated brain tumors with identical visual appearance, stiffness, and random bleeding points. Validated tier 1, tier 2, and advanced tier 2 metrics were used to assess bimanual psychomotor performance. Demographic data included weeks of neurosurgical elective and prior operative exposure. This pilot study was carried out at the McGill Neurosurgical Simulation Research and Training Center immediately following neurosurgical residency interviews at McGill University, Montreal, Canada. All 17 medical students interviewed were asked to participate, of which 16 agreed. Performances were clustered in definable top, middle, and bottom groups with significant differences for all metrics. Increased time spent playing music, increased applicant self-evaluated technical skills, high self-ratings of confidence, and increased skin closures statistically influenced performance on univariate analysis. A trend for both self-rated increased operating room confidence and increased weeks of neurosurgical exposure to increased blood loss was seen in multivariate analysis. Simulation technology identifies neurosurgical residency applicants with differing levels of technical ability. These results provide information for studies being developed for longitudinal studies on the acquisition, development, and maintenance of psychomotor skills. Technical abilities customized training programs that maximize individual resident bimanual psychomotor training dependant on continuously updated and validated metrics from virtual reality simulation studies should be explored.

The five minds of a manager.

PubMed

Gosling, Jonathan; Mintzberg, Henry

2003-11-01

Managers are told: Be global and be local. Collaborate and compete. Change, perpetually, and maintain order. Make the numbers while nurturing your people. To be effective, managers need to consider the juxtapositions in order to arrive at a deep integration of these seemingly contradictory concerns. That means they must focus not only on what they have to accomplish but also on how they have to think. When the authors, respectively the director of the Centre for Leadership Studies at the University of Exeter in the U.K. and the Cleghorn Professor of Management Studies at McGill University in Montreal, set out to develop a masters program for practicing managers, they saw that they could not rely on the usual MBA educational structure, which divides the management world into discrete business functions such as marketing and accounting. They needed an educational structure that would encourage synthesis rather than separation. Managing, they determined, involves five tasks, each with its own mind-set: managing the self (the reflective mind-set); managing organizations (the analytic mind-set); managing context (the worldly mind-set); managing relationships (the collaborative mind-set); and managing change (the action mind-set). The program is built on the exploration and integration of those five aspects of the managerial mind. The authors say it has proved powerful in the classroom and insightful in practice. Imagine the mind-sets as threads and the manager as weaver. Effective performance means weaving each mind-set over and under the others to create a fine, sturdy cloth.

Global Climate Models for the Classroom: The Educational Impact of Student Work with a Key Tool of Climate Scientists

Efforts to address climate change require public understanding of Earth and climate science. To meet this need, educators require instructional approaches and scientific technologies that overcome cultural barriers to impart conceptual understanding of the work of climate scientists. We compared student inquiry learning with now ubiquitous climate education toy models, data and tools against that which took place using a computational global climate model (GCM) from the National Aeronautics and Space Administration (NASA). Our study at McGill University and John Abbott College in Montreal, QC sheds light on how best to teach the research processes important to Earth and climate scientists studying atmospheric and Earth system processes but ill-understood by those outside the scientific community. We followed a pre/post, control/treatment experimental design that enabled detailed analysis and statistically significant results. Our research found more students succeed at understanding climate change when exposed to actual climate research processes and instruments. Inquiry-based education with a GCM resulted in significantly higher scores pre to post on diagnostic exams (quantitatively) and more complete conceptual understandings (qualitatively). We recognize the difficulty in planning and teaching inquiry with complex technology and we also found evidence that lectures support learning geared toward assessment exams.

Plastic Surgery Inclusion in the Undergraduate Medical Curriculum: Perception, Challenges, and Career Choice—A Comparative Study

Objective The undergraduate medical curriculum has been overcrowded with core learning outcomes with no formal exposure to plastic surgery. The aim of this study was to compare medical students from two educational settings for the basic understanding, preferred learning method, and factors influencing a career choice in plastic surgery. Design and Setting A prospective cohort study based on a web-based anonymous questionnaire sent to final year medical students at Birmingham University (United Kingdom), McGill University (Canada), and a control group (non-medical staff). The questions were about plastic surgery: (1) source of information and basic understanding; (2) undergraduate curriculum inclusion and preferred learning methods; (3) factors influencing a career choice. A similar questionnaire was sent to non-medical staff (control group). The data was analysed based on categorical outcomes (Chi-square χ2) and level of significance p ≤ 0.05. Results Questionnaire was analysed for 243 students (Birmingham, n = 171/332, 52%) (McGill n = 72/132, 54%). Birmingham students (14%) considered the word “plastic” synonymous with “cosmetic” more than McGill students (4%, p < 0.025). Teaching was the main source of knowledge for McGill students (39%, p < 0.001) while Birmingham students and control group chose the media (70%, p < 0.001). McGill students (67%) more than Birmingham (49%, p < 0.010) considered curriculum inclusion. The preferred learning method was lectures for McGill students (61%, p < 0.01) but an optional module for Birmingham (61%). A similar proportion (18%) from both student groups considered a career in plastic surgery. Conclusions Medical students recognised the need for plastic surgery inclusion in the undergraduate curriculum. There was a difference for plastic surgery source of information, operations, and preferred method of learning for students. The study highlighted the urgent need to reform plastic surgery undergraduate teaching in collaboration with national educational bodies worldwide. PMID:28630768

Context The hypothesis of a serotonin (5-hydroxytryptamine [5-HT]) dysfunction in obsessive-compulsive disorder (OCD) stems largely from the clinical efficacy of 5-HT reuptake inhibitors. Serotonergic abnormalities in the unmedicated symptomatic state, however, remain to be fully characterized. Objective To investigate brain regional 5-HT synthesis, as indexed by positron emission tomography and the α-[11C]methyl-L-tryptophan trapping constant (K*), in treatment-free adults meeting criteria for OCD. Design Between-group comparison. Setting Department of Psychiatry and Montreal Neurological Institute, McGill University, and Department of Psychology, McGill University Health Centre, Quebec, Canada. Participants Twenty-one medication-free patients with OCD (15 men with a mean [SD] age of 33.2 [9.3] years and 6 women with a mean [SD] age of 35.8 [7.1] years) and 21 healthy controls matched for age and sex (15 men with a mean [SD] age of 32.9 [10.1] years and 6 women with a mean [SD] age of 36.5.5 [8.6] years). Main Outcome Measure The α-[11C]methyl-L-tryptophan brain trapping constant K*, which was analyzed with Statistical Parametric Mapping (SPM8) and with proportional normalization (extent threshold of 100 voxels with a peak threshold of P≤.005). Results Compared with healthy controls, the patients with OCD exhibited significantly greater α-[11C]methyl-L-tryptophan trapping in the right hippocampus and left temporal gyrus (Brodmann area 20). In the larger sub-sample of all men, these same differences were also evident, as well as higher K* values in the caudate nucleus. Individual differences in symptom severity correlated positively with K* values sampled from the caudate and temporal lobe of the patients with OCD, respectively. There were no regions where the patients exhibited abnormally low K* values. Volumetric analyses found no morphometric alterations that would account for the group differences. Conclusion The results support previous reports of greater striatal and temporal lobe activity in patients with OCD than in healthy controls and suggest that these disturbances include a serotonergic component. Previously reported glucose metabolic disturbances in OCD involving the orbitofrontal and cingulate cortices, in comparison, might reflect postsynaptic changes in the serotonergic system.

This article examines the question of how universities can be encouraged to address the mental health concerns of GLBT-SQ people and communities from a perspective of solidarity. In so doing, the authors take a case study approach, using Project Interaction: The Gay, Lesbian, Bisexual and Two-Spirit Initiative of McGill University's School of Social Work, to critically reflect upon the challenges arising from the development of an alternative organization within academia. The purpose of this reflection is to highlight how normal operations at work on university campuses, and within health and allied health curriculum, can be disrupted with the goal of providing momentum for the creation of affirmative space, the advancement of educational initiatives, and the building of opportunities for social change.

Widespread penicillin usage rapidly resulted in the emergence of penicillin resistance in Staphylococcus aureus. However, new data suggest that penicillin susceptibility may be in a period of renaissance. The objective of our study was to quantify penicillin resistance in methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. We retrospectively reviewed all adult MSSA bacteremia from April 2010 to April 2015 at the McGill University Health Centre (Montreal, QC, Canada). Susceptibility to penicillin, erythromycin, clindamycin, and trimethoprim-sulfamethoxazole (TMP-SMX) was determined in accordance with the Clinical & Laboratory Standards Institute guidelines. There were 324 unique episodes of MSSA bacteremia. Ninety (28%) isolates were susceptible to penicillin, 229 (71%) to erythromycin, 239 (74%) to clindamycin, and 317 (98%) to TMP-SMX. Isolates that were penicillin resistant were more likely to also be resistant to other antibiotics, but a statistically significant association was apparent only for erythromycin resistance (76/234, 32.2% vs 19/90, 21.1%, P = .04). The median age of patients was 67.5 years (interquartile range 52-78) and overall in-hospital 30-day mortality was 16.3% (53 deaths). After adjustment for patient age, there was no association between penicillin resistance and either intensive care unit admission or death. More than one-quarter of patients with MSSA bacteremia potentially could be treated with parenteral penicillin, which may offer pharmacokinetic advantages over other beta-lactam drugs and potentially improved outcomes.

The purpose of this study is to investigate the effect of risk factors including International Normalized Ratio (INR) as well as the Partial Thromboplastin Time (PTT) scores on several outcomes, including hospital length of stay (LOS) and The Extended Glasgow Outcome Scale (GOSE) following TBI in the elderly population. Data were retrospectively collected on patients (n=982) aged 65 and above who were admitted post TBI to the McGill University Health Centre-Montreal General Hospital from 2000 to 2011. Age, Injury Severity Score (ISS), Glasgow Coma Scale score (GCS), type of trauma (isolated TBI vs polytrauma including TBI), initial CT scan results according to the Marshall Classification and the INR and PTT scores and prescriptions of antiplatelet or anticoagulant agents (AP/AC) were collected. Results also indicated that age, ISS and GSC score have an effect on the GOSE score. We also found that taking AC/AP has an effect on GOSE outcome, but that this effects depends on PTT, with lower odds of a worse outcome for those taking AC/AP agents as the PTT value goes up. However, this effect only becomes significant as the PTT value reaches 60 and above. Age and injury severity rather than antithrombotic agent intake are associated with adverse acute outcome such as GOSE in hospitalized elderly TBI patients. Copyright © 2017 Elsevier Ltd.

The Diabetes Prevention Program (DPP) is highly effective in promoting weight loss in overweight and obese individuals. However, one-on-one DPP sessions are costly. As a cost-saving alternative, a group version of the DPP, called Group Lifestyle Balance program (GLB), has been developed but has been shown to be less effective. The aim of this two-arm parallel randomized controlled trial is to increase the effectiveness of the GLB by integrating habit formation techniques, namely if-then plans and their mental practice, into the program. A total of 154 participants will be randomized to a standard or enriched GLB program. For the enriched GLB program, if-then plans and their mental practice will be integrated into the standard GLB program. Participants will be overweight or obese men and women (BMI of 28 to 45 kg/m2, waist circumference ≥ 88 for women, ≥ 102 for men, 18 to 75 years of age) who do less than 200 minutes of self-reported moderate or vigorous exercise per week. Measures will be completed at baseline, 3 months, post-intervention (12 months), and 12 months post-intervention (24 months). The primary outcome measure is weight loss at 3, 12, and 24 months. Secondary outcomes include percent reaching weight loss goal, physical activity at 3, 12, and 24 months, and weight-related risk factors (waist circumference, hemoglobin A1c, systolic/diastolic blood pressure, total cholesterol/HDL ratio). Standardized training of the life-style coaches, use of standardized manuals, and audio taping and reviewing of the sessions will ensure intervention fidelity. The study will provide evidence-based data on the effectiveness of an enhanced GLB intervention in promoting weight loss and in reducing weight-related risk factors for chronic health problems.

Assessment of neurosurgical technical skills involved in the resection of cerebral tumors in operative environments is complex. Educators emphasize the need to develop and use objective and meaningful assessment tools that are reliable and valid for assessing trainees' progress in acquiring surgical skills. The purpose of this study was to develop proficiency performance benchmarks for a newly proposed set of objective measures (metrics) of neurosurgical technical skills performance during simulated brain tumor resection using a new virtual reality simulator (NeuroTouch). Each participant performed the resection of 18 simulated brain tumors of different complexity using the NeuroTouch platform. Surgical performance was computed using Tier 1 and Tier 2 metrics derived from NeuroTouch simulator data consisting of (1) safety metrics, including (a) volume of surrounding simulated normal brain tissue removed, (b) sum of forces utilized, and (c) maximum force applied during tumor resection; (2) quality of operation metric, which involved the percentage of tumor removed; and (3) efficiency metrics, including (a) instrument total tip path lengths and (b) frequency of pedal activation. All studies were conducted in the Neurosurgical Simulation Research Centre, Montreal Neurological Institute and Hospital, McGill University, Montreal, Canada. A total of 33 participants were recruited, including 17 experts (board-certified neurosurgeons) and 16 novices (7 senior and 9 junior neurosurgery residents). The results demonstrated that "expert" neurosurgeons resected less surrounding simulated normal brain tissue and less tumor tissue than residents. These data are consistent with the concept that "experts" focused more on safety of the surgical procedure compared with novices. By analyzing experts' neurosurgical technical skills performance on these different metrics, we were able to establish benchmarks for goal proficiency performance training of neurosurgery residents. This study furthers our understanding of expert neurosurgical performance during the resection of simulated virtual reality tumors and provides neurosurgical trainees with predefined proficiency performance benchmarks designed to maximize the learning of specific surgical technical skills.

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. Specific to the findings of this study regarding the method of suicide attempt used, for example, limiting access to dangerous substances or large quantities of medications may help prevent or reduce suicide attempts in this population.

Three technologic projects with potentially patentable end results are slowly evolving in the Department of Obstetrics and Gynecology, McGill University and Royal Victoria Hospital. A tax shelter infusion of a significant amount of venture capital developed opportunities for all three projects over two years. The three projects--fetal heart rate tracing analysis related to fetal outcome, a distributed and intelligent data acquisition system and selected ultrasonic three dimensional imaging--were advanced considerably, and their results are expressed in outline. The effects of such infusions of business support into an environment of sparse research grant support have been extremely encouraging to the investigators, but the department, with its obligations of ongoing research, teaching and patient care, must develop the next steps with care, although one of the projects has been extended by an interested corporation.

Since May 1992 a small, 915-MHz profiler has been operated continuously in downtown Montreal. It is a five-beam system employing a microstrip array antenna, located atop a 14-story office building that houses several academic departments of McGill University. The data are used for research on precipitation physics and the clear-air reflectivity in addition to wind profiling. We are especially interested in situations in which the reflectivities of the clear air and the precipitation are comparable. This permits the study of interactions between the precipitation and the clear air, a new area of research made possible by wind profilers. On clear days in the summer, 30-min consensus winds can often be measured to an altitude of 3 km, but ground clutter in the antenna sidelobes interferes with measurements below 600 m. Rain when present often permits wind profiling down to 100 m and up to 6 km or higher. On cold winter days there are some periods when the reflectivity is too weak at all levels to permit wind estimation. Falling snow, however, provides readily detectable echoes and serves as a good tracer of the wind and so allows profiling over its full altitude extent. The best conditions for observing interactions between precipitation and the clear air are when light rain falls through a reflective layer associated with a frontal surface or inversion. Unexpectedly, flocks of migrating birds sometimes completely dominate the signal at night in the spring and fall seasons.

The McGill Quality of Life Questionnaire has been widely used with people with life-threatening illnesses without modification since its publication in 1996. With use, areas for improvement have emerged; therefore, various minor modifications were tested over time. To revise the McGill Quality of Life Questionnaire (McGill Quality of Life Questionnaire-Revised) while maintaining or improving its psychometric properties and length, keeping it as close as possible to the McGill Quality of Life Questionnaire to enable reasonable comparison with existing McGill Quality of Life Questionnaire literature. Data sets from eight studies were used (four studies originally used to develop the McGill Quality of Life Questionnaire, two to develop new McGill Quality of Life Questionnaire versions, and two with unrelated purposes). The McGill Quality of Life Questionnaire-Revised was developed using analyses of measurement invariance, confirmatory factor analysis, and calculation of correlations with the McGill Quality of Life Questionnaire's global quality of life item. Data were from 1702 people with life-threatening illnesses recruited from acute and palliative care units, palliative home care services, and oncology and HIV/AIDS outpatient clinics. The McGill Quality of Life Questionnaire-Revised consists of 14 items (plus the global quality of life item). A new Physical subscale was created combining physical symptoms and physical well-being and a new item on physical functioning. The Existential subscale was reduced to four items. The revised Support subscale, renamed Social, focuses more on relationships. The Psychological subscale remains unchanged. Confirmatory factor analysis results provide support for the measurement structure of the McGill Quality of Life Questionnaire-Revised. The overall scale has good internal consistency reliability ( α = 0.94). The McGill Quality of Life Questionnaire-Revised improves on and can replace the McGill Quality of Life Questionnaire since it contains improved wording, a somewhat expanded repertoire of concepts with fewer items, and a single subscale for the physical domain, while retaining good psychometric properties.

There is evidence that greater neighbourhood walkability (i.e., neighbourhoods with more amenities and well-connected streets) is associated with higher levels of total walking in Europe and in Asia, but it remains unclear if this association holds in the Canadian context and in chronic disease populations. We examined the relationships of different walkability measures to biosensor-assessed total walking (i.e., steps/day) in adults with type 2 diabetes living in Montreal (QC, Canada). Participants (60.5±10.4 years; 48.1% women) were recruited through McGill University-affiliated clinics (June 2006 to May 2008). Steps/day were assessed once per season for one year with pedometers. Neighbourhood walkability was evaluated through participant reports, in-field audits, Geographic Information Systems (GIS)-derived measures, and the Walk Score®. Relationships between walkability and daily steps were estimated using Bayesian longitudinal hierarchical linear regression models (n = 131). Participants who reported living in the most compared to the least walkable neighbourhoods completed 1345 more steps/day (95% Credible Interval: 718, 1976; Quartiles 4 versus 1). Those living in the most compared to the least walkable neighbourhoods (based on GIS-derived walkability) completed 606 more steps per day (95% CrI: 8, 1203). No statistically significant associations with steps were observed for audit-assessed walkability or the Walk Score®. Adults with type 2 diabetes who perceived their neighbourhoods as more walkable accumulated more daily steps. This suggests that knowledge of local neighborhood features that enhance walking is a meaningful predictor of higher levels of walking and an important component of neighbourhood walkability.

Many countries have reduced resident duty hours in an effort to promote patient safety and enhance resident quality of life. There are concerns that reducing duty hours may impact residents' learning opportunities. We (1) evaluated residents' perceptions of their current learning opportunities in a context of reduced duty hours, and (2) explored the perceived change in resident learning opportunities after call length was reduced from 24 continuous hours to 16 hours. We conducted an anonymous, cross-sectional online survey of 240 first-, second-, and third-year residents rotating through 3 McGill University-affiliated intensive care units (ICUs) in Montreal, Quebec, Canada, between July 1, 2012, and June 30, 2013. The survey investigated residents' perceptions of learning opportunities in both the 24-hour and 16-hour systems. Of 240 residents, 168 (70%) completed the survey. Of these residents, 63 (38%) had been exposed to both 24-hour and 16-hour call schedules. The majority of respondents (83%) reported that didactic teaching sessions held by ICU staff physicians were useful. However, of the residents trained in both approaches to overnight call, 44% reported a reduction in learner attendance at didactic teaching sessions, 48% reported a reduction in attendance at midday hospital rounds, and 40% reported a perceived reduction in self-directed reading after the implementation of the new call schedule. A substantial proportion of residents perceived a reduction in the attendance of instructor-directed and self-directed reading after the implementation of a 16-hour call schedule in the ICU.

To compare admission data and academic performances of medical students younger and older than 25, and to qualify older students' experiences and perceptions in medical school. The authors reviewed 1988-1991 data for applications to the McGill University Faculty of Medicine. Data included GPAs and MCAT scores, as well as ratings for reference letters, autobiographical statements, and interviews. For those same years, the authors measured students' academic performances in the preclinical and clinical years. The authors compared the data by students' age: "younger" students, aged 17 to 24; and "older" students, aged 25 and above. All enrolled students took the Derogatis Stress Profile, and the older students participated in focus groups. The older applicants had lower GPAs and MCAT scores, but higher interview and reference letter ratings. For older accepted students, basic science course scores were lower than those of younger students, but clinical scores did not differ significantly between the groups. The two groups had similar stress levels, although older students tested lower in driven behavior, relaxation potential, attitude posture, and hostility. In focus groups, the older students spoke of learning style differences, loss of social support, and loss of professional identity. Different scores in admission criteria suggest that McGill uses different standards to select older medical students. Older students admitted under different criteria, however, do just as well as do younger students by their clinical years. A broad-based study of admission criteria and outcomes for the older student population is warranted.

Unique Stellar System Gives Einstein a Thumbs-Up

NASA Astrophysics Data System (ADS)

2008-07-01

Taking advantage of a unique cosmic coincidence, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. The new data indicate that the famed physicist's 93-year-old theory has passed yet another test. Double Pulsar Graphic Artist's Conception of Double Pulsar System PSR J0737-3039A/B CREDIT: Daniel Cantin, DarwinDimensions, McGill University Click on image for more graphics. The scientists used the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) to make a four-year study of a double-star system unlike any other known in the Universe. The system is a pair of neutron stars, both of which are seen as pulsars that emit lighthouse-like beams of radio waves. "Of about 1700 known pulsars, this is the only case where two pulsars are in orbit around each other," said Rene Breton, a graduate student at McGill University in Montreal, Canada. In addition, the stars' orbital plane is aligned nearly perfectly with their line of sight to the Earth, so that one passes behind a doughnut-shaped region of ionized gas surrounding the other, eclipsing the signal from the pulsar in back. "Those eclipses are the key to making a measurement that could never be done before," Breton said. Einstein's 1915 theory predicted that, in a close system of two very massive objects, such as neutron stars, one object's gravitational tug, along with an effect of its spinning around its axis, should cause the spin axis of the other to wobble, or precess. Studies of other pulsars in binary systems had indicated that such wobbling occurred, but could not produce precise measurements of the amount of wobbling. "Measuring the amount of wobbling is what tests the details of Einstein's theory and gives a benchmark that any alternative gravitational theories must meet," said Scott Ransom of the National Radio Astronomy Observatory. The eclipses allowed the astronomers to pin down the geometry of the double-pulsar system and track changes in the orientation of the spin axis of one of them. As one pulsar's spin axis slowly moved, the pattern of signal blockages as the other passed behind it also changed. The signal from the pulsar in back is absorbed by the ionized gas in the other's magnetosphere. Pulsars, first discovered in 1967, are the "corpses" of massive stars that have exploded as supernovae. What is left after the explosion is a superdense neutron star that packs more than the mass of our Sun into the size of an average city. Beams of radio waves stream outward from the poles of the star's intense magnetic field and sweep around as the star rotates, as often as hundreds of times a second. The pair of pulsars studied with the GBT is about 1700 light-years from Earth. The average distance between the two is only about twice the distance from the Earth to the Moon. The two orbit each other in just under two and a half hours. "A system like this, with two very massive objects very close to each other, is precisely the kind of extreme 'cosmic laboratory' needed to test Einstein's prediction," said Victoria Kaspi, leader of McGill University's Pulsar Group. Theories of gravity don't differ significantly in "ordinary" regions of space such as our own Solar System. In regions of extremely strong gravity fields, such as near a pair of close, massive objects, however, differences are expected to show up. In the binary-pulsar study, General Relativity "passed the test" provided by such an extreme environment, the scientists said. "It's not quite right to say that we have now 'proven' General Relativity," Breton said. "However, so far, Einstein's theory has passed all the tests that have been conducted, including ours." Breton, Kaspi and Ransom worked with Michael Kramer of the Jodrell Bank Observatory at the University of Manchester in Great Britain; Maura McLaughlin of West Virginia University and the NRAO; Maxim Lyutikov of Purdue University and other colleagues in Canada, the U.S., France and Italy. The researchers presented their work in an article in the July 4 issue of Science.

Although eliminating financial barriers to care is a necessary condition for improving access to health services, it is not sufficient. Given the contrasting health systems with regard to financing and organization of health insurance in the United States and Canada, there is a long history of comparing these countries. We extend the empirical studies on the Canadian and US health systems by comparing access to ambulatory care as measured by hospitalization rates for ambulatory care sensitive conditions (ACSC) in Montreal and New York City. We find that, in New York, ACSC rates were more than twice as high (12.6 per 1000 population) as in Montreal (4.8 per 1000 population). After controlling for age, sex, and number of diagnoses, significant differences in ACSC rates are present in both cities, but are more pronounced in New York. Our findings are consistent with the hypothesis that universal, first-dollar health insurance coverage has contributed to lower ACSC rates in Montreal than New York. However, Montreal's surprisingly low ACSC rate calls for further research.

Socio-demographic characteristics (age, gender, marital state, infertility type & duration, previous IVF attempts; education, employment, income, ethnicity, spoken languages) and FertiQoL scores. In all, 1020 patients completed the questionnaires; of these, 752 (77.7%) non-immigrant Canadian citizens and 215 (22.3%) resident immigrants were included in the analysis. Median duration in Canada for immigrants was 4 years. Immigrants were more likely to have university/graduate degrees (75% versus 64%), to be unemployed (37% versus 13.1%) and to have lower annual household incomes (72.8% versus 39.5%, all P < 0.05). They also reported poorer QoL and achieved significantly lower scores in the emotional, mind/body, social, treatment and total FertiQoL domains. Multivariate analysis showed male gender, lower education level and Caucasian/European ethnicity to be significantly associated with higher QoL. Despite governmental funding of IVF, immigrants experience reduced fertility QoL, implying cost is not the only barrier to IVF use. The reduced QoL may stem from cross-cultural differences in infertility perception. This population may be at greater risk for depression and anxiety and should be flagged accordingly. Immigrants' fertility QoL is lower despite publicly funded IVF implying cost is not the only barrier to IVF use. © 2017 Royal College of Obstetricians and Gynaecologists.

The aim of this study was to verify the discriminative power of the most widely used pain assessment instruments. The sample consisted of 279 subjects divided into Fibromyalgia Group FM- 205 patients with fibromyalgia and Control Group CG-74 healthy subjects), mean age 49.29 +/- 10.76 years. Only 9 subjects were male, 6 in FM and 3 in CG. FM were outpatients from the Rheumatology Clinic of the University of São Paulo--Hospital das Clínicas (HCFMUSP); the CG included people accompanying patients and hospital staff with similar socio-demographic characteristics. Three instruments were used to assess pain: the McGill Pain Questionnaire MPQ, the Visual Analog Scale (VAS), and the Dolorimetry, to measure pain threshold on tender points (generating the TP index). In order to assess the discriminative power of the instruments the measurements obtained were submitted to descriptive analysis and inferential analysis using ROC Curve-sensibility (S), specificity (S1) and area under the curve (AUC)--and Contingence tables with Chi-square Test and odds ratio. Significance level was 0.05. Higher sensibility specificity and area under the curve was obtained by VAS (80% 80% and 0.864, respectively), followed by Dolorimetry (S 77% S177% and AUC 0.851), McGill Sensory (S 72% S167% and AUC 0.765) and McGill Affective (S 69% S1 67% and AUC 0.753). VAS presented the higher sensibility, specificity and AUC, showing the greatest discriminative power among the instruments. However, these values are considerably similar to those of Dolorimetry.

A joint project on the Ministry of Health, Addis Ababa University, the Jimma Institute of Health Services, the Gondar College of Health Sciences, and McGill University in Montreal, Canada is involved with working to improve the health care system in Ethiopia. The Ethiopian government has established postgraduate degrees in public health for district health managers, and overseas fellowships for students in order to train health professionals to work in 359 districts (awrajas). The emphasis is on district managers because of their link to the people, to stimulating community participation, and to coordinating activities. Training programs are available for physicians who have worked in rural areas for 2 years; completion of the program usually means placement as district health managers. One student was able to reduce respiratory illness among textile mill workers because of the success of his research thesis on byssinosis. 40% of Ethiopia has district health centers which provide primary health care and coordinate health resources. A 1st priority is convincing local leaders to construct latrines and provide safe sources of drinking water. The example of the functioning of the Suluta health district is provided. Of the 129,000 inhabitants, the health personnel and facilities provide for only 25% of the villages in the district. The district director is completing his thesis on field trials of oral rehydration therapy. Student research is supervised by physicians based at Addis Ababa University. An example is given of one such visit to a student studying adolescent sexual behavior and illegal abortion increases. Student work involved research, an action plan which identifies priorities for the area, and a health profile. Students learn how to compile data and plot graphs in a country where rural birth and death records are not kept. Record keeping, reference books and materials were also needed for the organization; technical resources were provided to this end. Computers and CD-ROMS have expended the resource base. Standards have improved since the initiation of the program, and the importance of the training was evident in the ability to handle the meningitis epidemic in 1989 and the coup in 1991. Economic conditions need to improve and be directed to health personnel, drugs, books and supplies.

Acquisition and Processing of High Resolution Hyperspectral Imageries for the 3d Mapping of Urban Heat Islands and Microparticles of Montreal

Mongeau, R.; Baudouin, Y.; Cavayas, F.

2017-10-01

Ville de Montreal wanted to develop a system to identify heat islands and microparticles at the urban scale and to study their formation. UQAM and UdeM universities have joined their expertise under the framework "Observatoire Spatial Urbain" to create a representative geospatial database of thermal and atmospheric parameters collected during the summer months. They innovated in the development of a methodology for processing high resolution hyperspectral images (1-2 m). In partnership with Ville de Montreal, they integrated 3D geospatial data (topography, transportation and meteorology) in the process. The 3D mapping of intraurban heat islands as well as air micro-particles makes it possible, initially, to identify the problematic situations for future civil protection interventions during extreme heat. Moreover, it will be used as a reference for the Ville de Montreal to establish a strategy for public domain tree planting and in the analysis of urban development projects.

Geometry Genetics and Evolution

Darwin argued that highly perfected organs such as the vertebrate eye could evolve by a series of small changes, each of which conferred a selective advantage. In the context of gene networks, this idea can be recast into a predictive algorithm, namely find networks that can be built by incremental adaptation (gradient search) to perform some task. It embodies a ``kinetic'' view of evolution where a solution that is quick to evolve is preferred over a global optimum. Examples of biochemical kinetic networks were evolved for temporal adaptation, temperature compensated entrainable clocks, explore-exploit trade off in signal discrimination, will be presented as well as networks that model the spatially periodic somites (vertebrae) and HOX gene expression in the vertebrate embryo. These models appear complex by the criterion of 19th century applied mathematics since there is no separation of time or spatial scales, yet they are all derivable by gradient optimization of simple functions (several in the Pareto evolution) often based on the Shannon entropy of the time or spatial response.

Surgical skills and simulation centers have been developed in recent years to meet the educational needs of practicing surgeons, residents, and students. The rapid pace of innovation in surgical procedures and technology, as well as the overarching desire to enhance patient safety, have driven the development of simulation technology and new paradigms for surgical education. McGill University has implemented an innovative approach to surgical education in the field of minimally invasive surgery. The goal is to measure surgical performance in the operating room using practical, reliable, and valid metrics, which allow the educational needs of the learner to be established and enable feedback and performance to be tracked over time. The GOALS system and the MISTELS program have been developed to measure operative performance and minimally invasive surgical technical skills in the inanimate skills lab, respectively. The MISTELS laparoscopic simulation-training program has been incorporated as the manual skills education and evaluation component of the Fundamentals of Laparoscopic Surgery program distributed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and the American College of Surgeons.

Neighbourhood Walkability and Daily Steps in Adults with Type 2 Diabetes

PubMed Central

Hajna, Samantha; Ross, Nancy A.; Joseph, Lawrence; Harper, Sam; Dasgupta, Kaberi

2016-01-01

Introduction There is evidence that greater neighbourhood walkability (i.e., neighbourhoods with more amenities and well-connected streets) is associated with higher levels of total walking in Europe and in Asia, but it remains unclear if this association holds in the Canadian context and in chronic disease populations. We examined the relationships of different walkability measures to biosensor-assessed total walking (i.e., steps/day) in adults with type 2 diabetes living in Montreal (QC, Canada). Materials and Methods Participants (60.5±10.4 years; 48.1% women) were recruited through McGill University-affiliated clinics (June 2006 to May 2008). Steps/day were assessed once per season for one year with pedometers. Neighbourhood walkability was evaluated through participant reports, in-field audits, Geographic Information Systems (GIS)-derived measures, and the Walk Score®. Relationships between walkability and daily steps were estimated using Bayesian longitudinal hierarchical linear regression models (n = 131). Results Participants who reported living in the most compared to the least walkable neighbourhoods completed 1345 more steps/day (95% Credible Interval: 718, 1976; Quartiles 4 versus 1). Those living in the most compared to the least walkable neighbourhoods (based on GIS-derived walkability) completed 606 more steps per day (95% CrI: 8, 1203). No statistically significant associations with steps were observed for audit-assessed walkability or the Walk Score®. Conclusions Adults with type 2 diabetes who perceived their neighbourhoods as more walkable accumulated more daily steps. This suggests that knowledge of local neighborhood features that enhance walking is a meaningful predictor of higher levels of walking and an important component of neighbourhood walkability.

Intracellular concentrations of sodium and potassium ions in a marine pseudomonad. J. Bacteriol. 87:510–518. 1964.—Washed cells of a marine pseudomonad were suspended in buffered salt solutions containing, in addition to MgSO4, NaCl and KCl at various concentrations. The cells were centrifuged from the medium and analyzed for Na+ and K+. Inulin and C14-carboxypolyglucose were employed to estimate the volume of extracellular fluid associated with the packed cells. Intracellular Na+ and K+ concentrations were determined by correcting for the amount of Na+ and K+ in the extracellular fluid. At all levels of Na+ in the suspending medium (0 to 1 m), the intracellular and extracellular Na+ concentrations within the limits of experimental error were the same. The intracellular K+ concentrations were approximately double the extracellular concentrations at the two levels of K+ tested (0.01 and 0.15 m) and were not influenced by the amount of Na+ present. Intracellular and extracellular Cl− concentrations were the same at the one level of Cl− examined. The intracellular fluid volume varied with the NaCl or KCl concentration of the suspending medium, being greatest in the absence of added salts, decreasing to a minimum at 0.3 m salt, and then increasing slightly at higher salt concentrations. Most of the intracellular Na+ could be removed by washing with solutions of MgSO4 or sucrose, but a small amount [10 to 15 μmoles/g (dry weight)] remained bound to the cells. PMID:14129666

Obsessive-compulsive personality disorder and suicidal behavior: evidence for a positive association in a sample of depressed patients.

Diaconu, Gabriel; Turecki, Gustavo

2009-11-01

To explore the association between obsessive-compulsive personality disorder (OCPD) and suicidal behavior. Subjects referred for a psychiatric consultation were evaluated with structured interviews for mood and personality disorders (the Structured Clinical Interview for DSM-III-R and the Structured Clinical Interview for DSM-III-R Axis II Disorders), a history of suicidal behavior, and levels of coping. A total of 311 subjects were investigated using a 3-group design to test the association between OCPD and suicidal behavior, controlling for the presence of depression. Subjects with OCPD and a history of depression were compared to depressed subjects without any Axis II diagnosis and to subjects without depression or personality disorders. The study was conducted at Verdun Community Psychiatric Clinic, Douglas Hospital, McGill University, in Montreal, Quebec, Canada, and subjects were recruited from 2003 until 2005. Subjects in the comorbid OCPD-depression group presented increased current and lifetime suicide ideation compared to the groups with depression alone or without depression or personality disorders (P = .004); they also had increased history of suicide attempts (P = .04), which were often multiple attempts (P = .01). They also scored lower on the Reasons for Living Inventory (RFL) and the Death Anxiety Questionnaire. Interestingly, comorbid OCPD-depression patients differed from patients with depression alone on the Moral Objections items of the RFL, on which individuals with OCPD-depression scored lowest. Limitations of this study were its cross-sectional design, retrospective sample, and limited generalizability to the population at large. Obsessive-compulsive personality disorder is a factor increasing risk for nonfatal suicidal behavior independently of risk conferred by depressive disorders.

To identify the factors that influence the use of dental services in 4-7-year-olds and in 10-13-year-olds resident in the cities of Talca (Chile) and Montreal (Canada). A nonprobabilistic cross-sectional study was carried out in 147 boys and girls in Talca and in 94 boys and girls in Montreal between 2009 and 2011. Sociodemographic variables were recorded in parents and children, including age and sex. Data were also gathered on parental education, family composition, and proximity to health centers within neighborhoods. The data were analyzed with Fisher's exact test and the robust Cox regression model (with constant time) with a significance level of 0,05. In Talca, parental education was significantly associated with dental care visits at least twice a year. The children of parents with university education were 2.20 times more likely to consult a dentist (95% CI: 1.30-3.73). Children whose parents perceived their children's health positively were 53% (OR = 0,47; 95% CI: 0,28-0,77) less likely to consult a dentist. In Montreal, the children of parents with university education were 2.10 times more likely to consult a dentist (95%CI: 1.17-3.76), while older children (10-13 years) were 2.11 (95% CI: 1.15-3.88) times more likely to consult a dentist. In both cities, parental education level was associated with the use of dental services. Copyright © 2012 SESPAS. Published by Elsevier Espana. All rights reserved.

The aim of this study was to determine the effects of pain and fatigue on daily life activities of systemic lupus erythematosus (SLE) patients. The study sample included 74 SLE patients who presented to outpatient departments of a university hospital and two local hospitals between 30.9.2009 and 15.5.2010. Data was collected using the Fatigue Severity Scale, Katz's Activity's Daily Living Index, Lawton and Brody's Instrumental Activities of Daily Living, and the McGill Pain Questionnaire. The mean scores were 6.0 (fatigue) on the Fatigue Severity Scale, 18.0 (independent) on the Daily Life Activities Index, 24.0 (independent) on the Instrumental Daily Life Activities Index, and 1.56 (discomforting) on the McGill Pain Scale for pain felt at the moment of questioning. A low-level negative relationship was observed between the scores on the Fatigue Severity Scale and the Daily Life Activities Index (p<0.05, r=-0.298), and between Fatigue and Instrumental Daily Life Activities scores (p<0.05, r=-0.354). A medium-level positive relationship was observed between the scores on the Fatigue Severity Scale and the McGill Pain Scale (p<0.05, r=0.478). This study determined that pain and fatigue affected the daily lives of SLE patients. The study should be repeated on a larger sample.

Training clinicians in cultural psychiatry: a Canadian perspective.

Kirmayer, Laurence J; Rousseau, Cécile; Guzder, Jaswant; Jarvis, G Eric

2008-01-01

The authors summarize the pedagogical approaches and curriculum used in the training of clinicians in cultural psychiatry at the Division of Social and Transcultural Psychiatry, McGill University. We reviewed available published and unpublished reports on the history and development of training in cultural psychiatry at McGill to identify the main orientations, teaching methods, curriculum, and course content. Student evaluations of teaching were reviewed. The training strategies and curriculum are related to the larger social context of Canadian society including the history of migration, current demography, and policies of multiculturalism. The McGill program includes core teaching, clinical rotations, an intensive summer program, and annual Advanced Study Institutes. The interdisciplinary training setting emphasizes general knowledge rather than specific ethnocultural groups, including: understanding the cultural assumptions implicit in psychiatric theory and practice; exploring the clinician's personal and professional identity and social position; evidence-based conceptual frameworks for understanding the interaction of culture and psychopathology; learning to use an expanded version of the cultural formulation in DSM-IV for diagnostic assessment and treatment planning; and developing skills for working with interpreters and culture-brokers, who mediate and interpret the cultural meaning and assumptions of patient and clinician. An approach to cultural psychiatry grounded in basic social science perspectives and in trainees' appreciation of their own background can prepare clinicians to respond effectively to the changing configurations of culture, ethnicity, and identity in contemporary health care settings.

2015-08-31

The Ohio State University (OSU) group contributed to the deliverables of the JET Collaboration three major products: 1. The code package iEBE-VISHNU for modeling the dynamical evolution of the soft medium created in relativistic heavy-ion collisions, from its creation all the way to final freeze-out using a hybrid approach that interfaces a free-streaming partonic pre-equilbrium stage with a (2+1)-dimensional viscous relativistic fluid dynamical stage for the quark-gluon plasma (QGP) phase and the microscopic hadron cascade UrQMD for the hadronic rescattering and freeze-out stage. Except for UrQMD, all dynamical evolution components and interfaces were developed at OSU and tested and implementedmore » in collaboration with the Duke University group. 2. An electromagnetic radiation module for the calculation of thermal photon emission from the QGP and hadron resonance gas stages of a heavy-ion collision, with emission rates that have been corrected for viscous effects in the expanding medium consistent with the bulk evolution. The electromagnetic radiation module was developed under OSU leadership in collaboration with the McGill group and has been integrated in the iEBE-VISHNU code package. 3. An interface between the Monte Carlo jet shower evolution and hadronization codes developed by the Wayne State University (WSU), McGill and Texas A&M groups and the iEBE-VISHNU bulk evolution code, for performing jet quenching and jet shape modification studies in a realistically modeled evolving medium that was tuned to measured soft hadron data. Building on work performed at OSU for the theoretical framework used to describe the interaction of jets with the medium, initial work on the jet shower Monte Carlo was started at OSU and moved to WSU when OSU Visiting Assistant Professor Abhijit Majumder accepted a tenure track faculty position at WSU in September 2011. The jet-hydro interface was developed at OSU and WSU and tested and implemented in collaboration with the McGill, Texas A&M, and LBNL groups.« less

An increase in dermatophyte infections caused by African species is reported in countries receiving African immigrants. Our goal was to determine the epidemiologic and clinical characteristics of tinea capitis in children infected with African species of dermatophytes in Montreal, Canada. Demographic and clinical data from medical records of children infected with African species of dermatophytes were retrieved retrospectively (2000-2016) at Sainte-Justine University Hospital Center. In Montreal, the number of tinea capitis cases caused by African species of dermatophytes increased sixfold over 17 years. African immigrant children (84%), men and boys (61%), and preschoolers (2-5 years old) (51%) were the most frequently affected in our 315 cases. Family contamination was frequent (45%). Referring physicians prescribed systemic antifungal treatment in 39% of cases and pediatric dermatologist consultants in 90%. Treatment failure to oral terbinafine occurred in 39% of Microsporum audouinii infections. In Montreal, there was a significant increase in tinea capitis caused by African species of dermatophytes. Microsporum audouinii is highly transmissible and often resistant to oral terbinafine. Recognizing tinea capitis trends in a given environment will improve patient care. © 2018 Wiley Periodicals, Inc.

Abstract Objective To examine the relationship between objective assessment of performance and self-rated competence immediately before and after participation in a required summative family medicine clerkship objective structured clinical examination (OSCE). Design Learners rated their competence (on a 7-point Likert scale) before and after an OSCE along 3 dimensions: general, specific, and professional competencies relevant to family medicine. Setting McGill University in Montreal, Que. Participants All 168 third-year clinical clerks completing their mandatory family medicine rotation in 2010 to 2011 were invited to participate. Main outcome measures Self-ratings of competence and objective performance scores were compared, and were examined to determine if OSCEs could be a “corrective” tool for self-rating perceived competence (ie, if the experience of undergoing an assessment might assist learners in recalibrating their understanding of their own performance). Results A total of 140 (83%) of the third-year clinical clerks participated. Participating in an OSCE decreased learners’ ratings of perceived competence (pre-OSCE score = 4.9, post-OSCE score = 4.7; F1,3192 = 4.2; P < .05). Learners’ mean self-rated competence for all categories of behaviour (before and after) showed no relationship to OSCE performance (r < 0.12 and P > .08 for all), nor did ratings of station-relevant competence (before and after) (r < 0.19 and P > .09 for all). Ratings of competence before and after the OSCE were correlated for individual students (r > 0.40 and P < .001 for all). Conclusion After the OSCE, students’ self-ratings of perceived competence had decreased, and these ratings had little relationship to actual performance, regardless of the specificity of the rated competency. Discordance between perceived and actual competence is neither novel nor unique to family medicine. However, this discordance is an important consideration for the development of competency-based curricula. PMID:28404722

Abstract The foundations for language and literacy are set in utero when babies hear the tone of their mother’s voice (1). There is strong evidence of a positive relationship between early literacy experiences and language and academic outcomes (2). Unfortunately, many parents do not know about the benefits of reading to and with young children, and many children enter school without the basic skills needed to learn to read and succeed. Physicians who have contact with young families are in a distinctive position to promote reading, though despite its evidence base, it has not yet become a universal intervention. A short description of the projects at the Montreal Children’s Hospital is provided. PMID:29479189

2015-01-01

Abstract Objective To assess use of the remediation instrument that has been implemented in training sites at the University of Montreal in Quebec to support faculty in diagnosing and remediating resident academic difficulties, to examine whether and how this particular remediation instrument improves the remediation process, and to determine its effects on the residents’ subsequent rotation assessments. Design A multimethods approach in which data were collected from different sources: remediation plans developed by faculty, program statistics for the corresponding academic years, and students’ academic records and rotation assessment results. Setting Family medicine residency program at the University of Montreal. Participants Family medicine residents in academic difficulty. Main outcome measures Assessment of the content, process, and quality of remediation plans, and students’ academic and rotation assessment results (successful, below expectations, or failure) both before and after the remediation period. Results The framework that was developed for assessing remediation plans was used to analyze 23 plans produced by 10 teaching sites for 21 residents. All plans documented cognitive problems and implemented numerous remediation measures. Although only 48% of the plans were of good quality, implementation of a remediation plan was positively associated with the resident’s success in rotations following the remediation period. Conclusion The use of remediation plans is well embedded in training sites at the University of Montreal. The residents’ difficulties were mainly cognitive in nature, but this generally related to deficits in clinical reasoning rather than knowledge gaps. The reflection and analysis required to produce a remediation plan helps to correct many academic difficulties and normalize the academic career of most residents in difficulty. Further effort is still needed to improve the quality of plans and to support teachers.

Quenching of Particle-Gas Combustible Mixtures Using Electric Particulate Suspension (EPS) and Dispersion Methods

Colver, Gerald M.; Goroshin, Samuel; Lee, John H. S.

2001-01-01

A cooperative study is being carried out between Iowa State University and McGill University. The new study concerns wall and particle quenching effects in particle-gas mixtures. The primary objective is to measure and interpret flame quenching distances, flammability limits, and burning velocities in particulate suspensions. A secondary objective is to measure particle slip velocities and particle velocity distribution as these influence flame propagation. Two suspension techniques will be utilized and compared: (1) electric particle suspension/EPS; and (2) flow dispersion. Microgravity tests will permit testing of larger particles and higher and more uniform dust concentrations than is possible in normal gravity.

The Croonian lectures of 1917: a McGill pathologist confronts the biologists of England.

PubMed

Buttolph, Mike

2010-11-01

John George Adami (1862-1926) qualified in medicine at Manchester and in 1892 was appointed professor of pathology at McGill University. At the invitation of the Royal College of Physicians (in London) he delivered the Croonian Lectures in 1917. He chose the title 'Adaptation and disease; the contribution of medical research to the study of evolution'. Adami believed that medical work had brought to light important facts about heredity that had not been communicated adequately to biological scientists. He used the lectures to describe this work, placing particular emphasis on his contention that acquired characters are inherited. At this time the medical audience at Adami's lectures would have been generally sympathetic to the idea that acquired characters can be inherited, though many leading British biologists were not sympathetic. Adami hoped that a concise review of the medical findings would persuade the biologists to his point of view or at least would be the starting point for a serious discussion of his evidence. However, the biologists were not persuaded and, although there were acrimonious personal exchanges, there was no scientific debate.

[Purpose] The aim of this study was to compare the effects of "McGill stabilization exercises" and "conventional physiotherapy" on pain, functional disability and active back flexion and extension range of motion in patients with chronic non-specific low back pain. [Subjects and Methods] Thirty four patients with chronic non-specific low back pain were randomly assigned to McGill stabilization exercises group (n=17) and conventional physiotherapy group (n=17). In both groups, patients performed the corresponding exercises for six weeks. The visual analog scale (VAS), Quebec Low Back Pain Disability Scale Questionnaire and inclinometer were used to measure pain, functional disability, and active back flexion and extension range of motion, respectively. [Results] Statistically significant improvements were observed in pain, functional disability, and active back extension range of motion in McGill stabilization exercises group. However, active back flexion range of motion was the only clinical symptom that statistically increased in patients who performed conventional physiotherapy. There was no significant difference between the clinical characteristics while compared these two groups of patients. [Conclusion] The results of this study indicated that McGill stabilization exercises and conventional physiotherapy provided approximately similar improvement in pain, functional disability, and active back range of motion in patients with chronic non-specific low back pain. However, it appears that McGill stabilization exercises provide an additional benefit to patients with chronic non-specific low back, especially in pain and functional disability improvement.

"Missing Link" Revealing Fast-Spinning Pulsar Mysteries

NASA Astrophysics Data System (ADS)

2009-05-01

Astronomers have discovered a unique double-star system that represents a "missing link" stage in what they believe is the birth process of the most rapidly-spinning stars in the Universe -- millisecond pulsars. "We've thought for some time that we knew how these pulsars get 'spun up' to rotate so swiftly, and this system looks like it's showing us the process in action," said Anne Archibald, of McGill University in Montreal, Canada. Pulsar and Companion Neutron star with accretion disk (left) drawing material from companion star (right). CREDIT:Bill Saxton, NRAO/AUI/NSF Animations of this system and its evolution. Pulsars are superdense neutron stars, the remnants left after massive stars have exploded as supernovae. Their powerful magnetic fields generate lighthouse-like beams of light and radio waves that sweep around as the star rotates. Most rotate a few to tens of times a second, slowing down over thousands of years. However, some, dubbed millisecond pulsars, rotate hundreds of times a second. Astronomers believe the fast rotation is caused by a companion star dumping material onto the neutron star and spinning it up. The material from the companion would form a flat, spinning disk around the neutron star, and during this period, the radio waves characteristic of a pulsar would not be seen coming from the system. As the amount of matter falling onto the neutron star decreased and stopped, the radio waves could emerge, and the object would be recognized as a pulsar. This sequence of events is apparently what happened with a binary-star system some 4000 light-years from Earth. The millisecond pulsar in this system, called J1023, was discovered by the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT) in West Virginia in 2007 in a survey led by astronomers at West Virginia University and the National Radio Astronomy Observatory (NRAO). The astronomers then found that the object had been detected by NSF's Very Large Array (VLA) radio telescope during a large sky survey in 1998, and had been observed in visible light by the Sloan Digital Sky Survey in 1999, revealing a Sun-like star. When observed again in 2000, the object had changed dramatically, showing evidence for a rotating disk of material, called an accretion disk, surrounding the neutron star. By May of 2002, the evidence for this disk had disappeared. "This strange behavior puzzled astronomers, and there were several different theories for what the object could be," said Ingrid Stairs of the University of British Columbia, who has been visiting the Australia Telescope National Facility and Swinburne University this year. The 2007 GBT observations showed that the object is a millisecond pulsar, spinning 592 times per second. "No other millisecond pulsar has ever shown evidence for an accretion disk," Archibald said. "We know that another type of binary-star system, called a low-mass X-ray binary (LMXB), also contains a fast-spinning neutron star and an accretion disk, but these don't emit radio waves. We've thought that LMXBs probably are in the process of getting spun up, and will later emit radio waves as a pulsar. This object appears to be the 'missing link' connecting the two types of systems," she explained. "It appears this thing has flipped from looking like an LMXB to looking like a pulsar, as it experienced an episode during which material pulled from the companion star formed an accretion disk around the neutron star. Later, that mass transfer stopped, the disk disappeared, and the pulsar emerged," said Scott Ransom of the NRAO. The scientists have studied J1023 in detail with the GBT, with the Westerbork radio telescope in the Netherlands, with the Arecibo radio telescope in Puerto Rico, and with the Parkes radio telescope in Australia. Their results indicate that the neutron star's companion has less than half the Sun's mass, and orbits the neutron star once every four hours and 45 minutes. "This system gives us an unparalled 'cosmic laboratory' for studying how millisecond pulsars evolve," Stairs said. Maura McLaughlin, of West Virginia University, agrees: "Future observations of this system at radio and other wavelengths are sure to hold many surprises." Archibald, Ransom, Stairs and McLaughlin are members of an international scientific team with representatives from McGill University, the University of British Columbia, the NRAO, West Virginia University, and others. The scientists announced their discovery in the May 21 online issue of the journal Science.

Preferences for body type and body characteristics associated with attractive and unattractive bodies: Jackson and McGill revisited.

PubMed

Rosenfeld, L B; Stewart, S C; Stinnett, H J; Jackson, L A

1999-10-01

The present investigation replicates Jackson and McGill's study (1996) and extends it by considering the effects of respondents' own height, weight, and body mass on perceptions of attractiveness. Results, although generally supportive of those found by Jackson and McGill, point to the influence of respondents' own physical characteristics in the process of perceptions of attractiveness: only 1 of Jackson and McGill's 3 (of a possible 19) differences between responses of African- and Euro-American women was corroborated (the importance of silky hair for Euro-American women), whereas a second difference (the importance of round buttocks for African-American women) disappeared when controlling for respondents' weight, height, and body mass. Although differences between the two investigations may be attributed to regional differences in the surveyed students (Michigan and North Carolina), the small effect of one's own weight, height, and body mass in assessing an other-sex person's attractiveness may reflect adherence to norms learned very early in life that are subject to regional variations.

Montreal, one of the most civilized and cosmopolitan of North American cities, is the 2nd city in Canada in size and the largest French-speaking city. Of the 2.8 million people who lived there at census time in 1981, 45% chose both French and English as their official language, 41% chose French, and 1% used some other language. Fully 68% of Montreal residents said their mother tongue was French, and 68% also said they spoke French at home. The importance of bilingualism to the business culture of Montreal cannot be overemphasized. In the last decade, French-Canadians have taken an increasingly stronger role in business. Upper-middle-class suburbs that as little as 10 years ago had only 10% of their residents who were of French-Canadian descent now have as many as 50-60% of their residents who are French-Canadians. Most residents of Montreal willingly learn 2 languages. US firms should assume that all representatives who are sent to Montreal should be fluent in both French and English. Montreal's 2,828,349 people create a population density of 1004.9 persons per square kilometer. Montreal has 665 census tracts, which are described in the Metropolitan Atlas Series. Nearly 62% of Montreal's population fall between the ages of 20 and 64--the prime working ages. Although Montreal is 79% Catholic, it does not have the high fertility levels often associated with Catholic areas. There were 1,026,920 households in Montreal in 1981 with an average of 2.7 persons per household. 71% of these were census family households. Montreal had 1,026,895 occupied dwellings in 1985 with an average of 5 rooms each. About 71% of the population aged 15 and over that were not in school were in the labor force; 41% of the labor force was female. The largest employment category for men was manufacturing (16%) and the largest for women was clerical work (39%).

Linguistic adaptation of the Russian version of the Short-form McGill Pain Questionnaire-2 (SF-MPQ-2), which is conceptually equivalent to the original questionnaire. The adaptation of the Russian version of SF-MPQ-2 was performed in accordance to established rules in several stages by two independent translators with the development of a consensus Russian version and its back translation by two independent translators and development of a consensus English version. The final Russian SF-MPQ-2 version was then created. The Russian version of the Short-form McGill Pain Questionnaire-2 (SF-MPQ-2-RU) was generated based on the established rules. This version was legally registered by the right holder - Mapi Research Trust and recommended for research in the Russian Federation.

Medicine, morality, and the market.

PubMed

Owen, D

1984-07-07

In extracts from a lecture given at McGill University, the author describes the rise of a marketing or corporate ethos in medicine, stemming from economic constraints and the demographic pressures of aging populations in the U.S., Canada, and the United Kingdom. To counter the trend to corporate rather than public policy making in medicine, he advocates a holistic approach to health care, a revival of interest in preventive health, and encouragement of the self-help movement. Owen calls for a reorientation of medical attitudes so that traditional moral values of medicine present a "counterweight to the mechanistic, technological, cost-effectiveness of the market place."

This article, using revealing statements from contemporary correspondence, traces the eventful life of Harriet Brooks, one of Ernest Rutherford's most valued research students and collaborators at McGill University. Brooks performed some of the crucial experiments in the early work on radioactivity; her work led her to the Cavendish where she did work with J. J. Thomson. Still later, she worked with Marie Curie, to whom Rutherford favorably compared her. Despite Brooks' achievements and promise, she finally relinquished her research career when faced with insurmountable objections to women who wished to have both a professional and a married life.

To compare efficacies of 2 active programs in the management of chronic low back pain (CLBP). This prospective, stratified, randomized single-blinded controlled study was conducted in the Department of Rehabilitation Medicine, King Abdullah University Hospital, Irbid, Jordan, between February and December 2010. A total of 100 patients were randomized to either 6-weeks of multidisciplinary rehabilitation (group A) or therapist-assisted exercise (group B). At baseline and 6 weeks, the visual analogue scale (VAS) pain score was estimated, as a primary outcome measure. McGill pain score, Oswestry Disability Index (ODI), trunk forward flexion and extension, left and right lateral bending, were applied before and after treatment and were employed as secondary outcome measures. All outcome measures significantly improved in group A after treatment, compared with group B. The VAS, McGill, ODI scores, left and right lateral bending decreased significantly, whereas forward and backward bending increased. A significant number of patients returned to work in group A at the end of 6 weeks, compared with group B. These effects were maintained over 12 and 24 weeks of follow-up. Multidisciplinary rehabilitation improved functional indices and pain scale scores in group A compared with B. This would be an effective strategy in CLBP management.

Elharram, Malik; Dinh, Trish; Lalande, Annie; Ge, Susan; Gao, Sophie; Noël, Geoffroy

As health care delivery increasingly requires providers to cross international borders, medical students at McGill University, Canada, developed a multidirectional exchange program with Haiti and Rwanda. The program integrates surgery, pathology, anatomy, research methodology, and medical education. The aim of the present study was to explore the global health value of this international training program to improve medical education within the environment of developing countries, such as Haiti and Rwanda, while improving sociocultural learning of Canadian students. Students from the University of Kigali, Rwanda and Université Quisqueya, Haiti, participated in a 3-week program at McGill University. The students spanned from the first to sixth year of their respective medical training. The program consisted of anatomy dissections, surgical simulations, clinical pathology shadowing, and interactive sessions in research methodology and medical education. To evaluate the program, a survey was administered to students using a mixed methodology approach. Common benefits pointed out by the participants included personal and professional growth. The exchange improved career development, sense of responsibility toward one's own community, teaching skills, and sociocultural awareness. The participants all agreed that the anatomy dissections improved their knowledge of anatomy and would make them more comfortable teaching the material when the returned to their university. The clinical simulation activities and shadowing experiences allowed them to integrate the different disciplines. However, the students all felt the research component had too little time devoted to it and that the knowledge presented was beyond their educational level. The development of an integrated international program in surgery, pathology, anatomy, research methodology, and medical education provided medical students with an opportunity to learn about differences in health care and medical education between the 3 countries. This exchange demonstrated that a crosscultural near-peer teaching environment can be an effective and sustainable method of medical student-centered development in global health.

Jaffe, Peter G; Berman, Helene; MacQuarrie, Barb

2011-09-01

The importance of Canadian research on violence against women became a national focus after the 1989 murder of 14 women at École Polytechnique in Montreal. This tragedy led to several federal government studies that identified a need to develop centers for applied research and community-university alliances on violence against women. One such center is the Centre for Research & Education on Violence against Women and Children. The Centre was founded in London, Canada in 1992 out of a partnership of a university, a community college, and community services. The centre's history and current activities are summarized as a model for the development and sustainability of similar centers.

Clarence Sumner Greene, Sr.: the first African-American neurosurgeon.

PubMed

McClelland, Shearwood; Harris, Kimbra S

2006-12-01

Largely because of the advances of the Civil Rights movement in the mid-20th century, an increasing number of African-Americans have had the opportunity to become physicians and enter the distinguished field of neurosurgery. Many have made the most of this opportunity, becoming prominent in both academics and private practice. Unfortunately, the details regarding the first African-American neurosurgeon, Clarence Sumner Greene, Sr., have remained in relative obscurity. Born on December 26, 1901 in Washington, D.C., Dr. Greene received his M.D. from the Howard University College of Medicine with distinction in 1936. After 7 years of general surgery residency and 4 years as a professor of surgery at Howard University, he was granted the opportunity by the legendary Wilder G. Penfield to train in neurosurgery at the world-renowned Montreal Neurological Institute from 1947 to 1949. Receiving high praise from Dr. Penfield, Dr. Greene became the first African-American certified by the American Board of Neurological Surgery on October 22, 1953. Subsequently, he was appointed as chair of neurosurgery at Howard University, where he successfully treated intracranial aneurysms, brain tumors, and herniated intervertebral discs until his tragic death in 1957. The diligence and perseverance of Clarence Sumner Greene, Sr., M.D., D.D.S., F.A.C.S. enabled him to overcome incredible odds to become the first African-American neurosurgeon, trained by Dr. Penfield at the Montreal Neurological Institute. A true pioneer, his achievements have opened the door for subsequent African-Americans to enhance the field of neurosurgery.

The conventional history of paediatric cardiology teaches that it was Helen Taussig who founded the cardiac clinic for children at the Harriet Lane Home of the Johns Hopkins School of Medicine in 1930, when Edwards Park appointed her director of the clinic.1,2 However, the story was more complex than that, and involved the collaboration of institutions and the frustrations, doubts, and passions of both Park and Taussig. In this article, I explore the history in more depth through published works, and material preserved at the McGill University Archives, the Rockefeller Foundation Archives, and the Alan Chesney Medical Archives at Johns Hopkins.

This paper discusses results from a pilot study conducted in the spring of 2014 among young adults living in Montreal. The main objective of this study was to assess the relation between perception of the Charter of Quebec Values, 1 self-identification, perception of intercommunity relations, perceived discrimination, and psychological well-being in young students enrolled in undergraduate or graduate programs of a francophone university in Montreal. A total of 441 students (30.5% male, 69.5% female) took part in a web survey designed by the research team. The data analyses and results suggest that the debate around the Charter of Quebec values was associated with a shift from a predominantly positive perception of intercommunity relations to a predominantly negative one, particularly among women, immigrants, and those who self-identified as cultural or religious minorities. In addition, more than 30% of participants reported having experienced some form of ethnic or religious discrimination since the Charter was released (personally or as a witness). This was particularly the case among immigrants, as well as those who self-identified as bicultural or from cultural or religious minority groups. This study's results thus highlight the exacerbation of intercommunity tensions linked to the public debate around identity and intercommunity relations in Quebec. © The Author(s) 2016.

Nonlinear and Nonequilibrium Spin Injection in Magnetic Tunneling Junctions

Quantitative analysis of charge and spin quantum transport in spintronic devices requires an atomistic first principles approach that can handle nonlinear and nonequilibrium transport conditions. We have developed an approach for this purpose based on real space density functional theory (DFT) carried out within the Keldysh nonequilibrium Green's function formalism (NEGF). We report theoretical analysis of nonlinear and nonequilibrium spin injection and quantum transport in Fe/MgO/Fe trilayer structures as a function of external bias voltage. Devices with well relaxed atomic structures and with FeO oxidization layers are investigated as a function of external bias voltage. We also report calculations of nonequilibrium spin injection into molecular layers and graphene. Comparisons to experimental data will be presented.

- In the early 1900s, it was common practice to retain, prepare, and display instructive pathologic specimens to teach pathology to medical trainees and practitioners; these collections were called medical museums. Maude Abbott established her reputation by developing expertise in all aspects of medical museum work. She was a founder of the International Association of Medical Museums (later renamed the International Academy of Pathology) and became an internationally renowned expert on congenital heart disease. Her involvement in the Canadian Medical War Museum (CMWM) is less well known. - To explore Abbott's role in the development of the CMWM during and after World War I and to trace its history. - Available primary and secondary historical sources were reviewed. - Instructive pathologic specimens derived from Canadian soldiers dying during World War I were shipped to the Royal College of Surgeons in London, which served as a clearinghouse for museum specimens from Dominion forces. The Canadian specimens were repatriated to Canada, prepared by Abbott, and displayed at several medical meetings. Abbott, because she was a woman, could not enlist and so she reported to a series of enlisted physicians with no expertise in museology. Plans for a permanent CMWM building in Ottawa eventually failed and Abbott maintained the collection at McGill (Montreal, Quebec, Canada) until her death in 1940. We trace the CMWM after her death. - Sadly, after Abbott had meticulously prepared these precious teaching specimens so that their previous owners' ultimate sacrifice would continue to help their military brethren, the relics were bureaucratically lost.

In 1974, Mario Molina and F. Sherwood Rowland warned that chlorofluorocarbons (CFCs) could destroy the stratospheric ozone layer that protects Earth from harmful ultraviolet radiation. In the decade after scientists documented the buildup and long lifetime of CFCs in the atmosphere; found the proof that CFCs chemically decomposed in the stratosphere and catalyzed the depletion of ozone; quantified the adverse effects; and motivated the public and policymakers to take action. In 1987, 24 nations plus the European Community signed the Montreal Protocol. Today, 25 years after the Montreal Protocol was agreed, every United Nations state is a party (universal ratification of 196 governments); all parties are in compliance with the stringent controls; 98% of almost 100 ozone-depleting chemicals have been phased out worldwide; and the stratospheric ozone layer is on its way to recovery by 2065. A growing coalition of nations supports using the Montreal Protocol to phase down hydrofluorocarbons, which are ozone safe but potent greenhouse gases. Without rigorous science and international consensus, emissions of CFCs and related ozone-depleting substances (ODSs) could have destroyed up to two-thirds of the ozone layer by 2065, increasing the risk of causing millions of cancer cases and the potential loss of half of global agricultural production. Furthermore, because most, ODSs are also greenhouse gases, CFCs and related ODSs could have had the effect of the equivalent of 24-76 gigatons per year of carbon dioxide. This critical review describes the history of the science of stratospheric ozone depletion, summarizes the evolution of control measures and compliance under the Montreal Protocol and national legislation, presents a review of six separate transformations over the last 100 years in refrigeration and air conditioning (A/C) technology, and illustrates government-industry cooperation in continually improving the environmental performance of motor vehicle A/C.

The validation of McGill quality-of-life questionnaire (MQOLQ) in mainland China, which had already been used in multicultural palliative care background including Hong Kong and Taiwan, remained unknown. Eligible patients completed the translated Chinese version of McGill questionnaires (MQOL-C), which had been examined before the study. Construct validity was preliminarily assessed through exploratory factor analysis extracting 4 factors that construct a new hypothesis model and then the original model was proved to be better confirmed by confirmatory factor analysis. Internal consistency of all the subscales was within 0.582 to 0.917. Furthermore, test-retest reliability ranged from 0.509 to 0.859, which was determined by Spearman rank correlation coefficient. Face validation and feasibility also confirm the good validity of MQOL-C. The MQOL-C has satisfied validation in mainland Chinese patients with cancer, although cultural difference should be considered while using it. © The Author(s) 2014.

Application of heat pipe technology in permanent mold casting of nonferrous alloys

NASA Astrophysics Data System (ADS)

Elalem, Kaled

The issue of mold cooling is one, which presents a foundry with a dilemma. On the one hand; the use of air for cooling is safe and practical, however, it is not very effective and high cost. On the other hand, water-cooling can be very effective but it raises serious concerns about safety, especially with a metal such as magnesium. An alternative option that is being developed at McGill University uses heat pipe technology to carry out the cooling. The experimental program consisted of designing a permanent mold to produce AZ91E magnesium alloy and A356 aluminum alloy castings with shrinkage defects. Heat pipes were then used to reduce these defects. The heat pipes used in this work are novel and are patent pending. They are referred to as McGill Heat Pipes. Computer modeling was used extensively in designing the mold and the heat pipes. Final designs for the mold and the heat pipes were chosen based on the modeling results. Laboratory tests of the heat pipe were performed before conducting the actual experimental plan. The laboratory testing results verified the excellent performance of the heat pipes as anticipated by the model. An industrial mold made of H13 tool steel was constructed to cast nonferrous alloys. The heat pipes were installed and initial testing and actual industrial trials were conducted. This is the first time where a McGill heat pipe was used in an industrial permanent mold casting process for nonferrous alloys. The effects of cooling using heat pipes on AZ91E and A356 were evaluated using computer modeling and experimental trials. Microstructural analyses were conducted to measure the secondary dendrite arm spacing, SDAS, and the grain size to evaluate the cooling effects on the castings. The modeling and the experimental results agreed quite well. The metallurgical differences between AZ91E and A356 were investigated using modeling and experimental results. Selected results from modeling, laboratory and industrial trials are presented. The results show a promising future for heat pipe technology in cooling permanent molds for the casting of nonferrous alloys.

To determine the feasibility and effectiveness of a learner-created virtual patient (VP) curriculum for postgraduate year 2 surgical residents. Using a social-constructivist model of learning, we designed a learner-created VP curriculum to help postgraduate year 2 residents prepare for their in-training surgical examination. Each resident was assigned to create a VP curriculum based on the learning objectives for this examination, and VP cases were then disseminated to all residents for completion. To measure the learning effects of the curriculum, participants completed 2 simulated in-training examinations, both at the beginning and at the end of the intervention. Study participants also participated in a focus group and completed an online questionnaire about the perceived learning value of the curriculum. The study was conducted at the McGill University Health Centre, a tertiary care hospital in Montreal, Canada. In total, 24 residents from 7 surgical specialties completed both the pretest and posttest, as well as took part in the creation of a VP curriculum. Of those 24 residents, only 19 residents completed the cases created by their peers, with 7 completing greater than 50% of the cases and 12 completing less than 50%. In all 17 residents responded to the online questionnaire and 11 residents participated in the focus group. The VP curriculum failed to improve scores from pretest (59.6%, standard deviation = 8.1) to posttest (55.4%, standard deviation = 6.6; p = 0.01) on the simulated in-training examination. Nonetheless, survey results demonstrated that most residents felt that creating a VP case (89%) and completing cases created by their peers (71%) had educational value. Overall, 71% preferred active participation in a curriculum to traditional didactic teaching. The focus group identified time-related constraints, concern about the quality of the peer-created cases, and questioning of the relationship between the curriculum and the Surgical Foundations examination as barriers to the success of the curriculum. Despite the fact that a learner-created VP curriculum did not improve scores on a mock in training examination, residents viewed this intervention as a valuable educational experience. Although there were barriers to the implementation of a learner-created curriculum, it is nonetheless important to try and integrate pedagogical concepts into the instructional design of curricula for surgical residents.

Front line providers of care are frequently lacking in knowledge on and sensitivity to social and structural determinants of underprivileged patients' health. Developing and evaluating approaches to raising health professional awareness and capacity to respond to social determinants is a crucial step in addressing this issue. McGill University, in partnership with Université de Montréal, Québec dental regulatory authorities, and the Québec anti-poverty coalition, co-developed a continuing education (CE) intervention that aims to transfer knowledge and improve the practices of oral health professionals with people living on welfare. Through the use of original educational tools integrating patient narratives and a short film, the onsite course aims to elicit affective learning and critical reflection on practices, as well as provide staff coaching. A qualitative case study was conducted, in Montreal Canada, among members of a dental team who participated in this innovative CE course over a period of four months. Data collection consisted in a series of semi-structured individual interviews conducted with 15 members of the dental team throughout the training, digitally recorded group discussions linked to the CE activities, clinic administrative documents and researcher-trainer field notes and journal. In line with adult transformative learning theory, interpretive analysis aimed to reveal learning processes, perceived outcomes and collective perspectives that constrain individual and organizational change. The findings presented in this article consist in four interactive themes, reflective of clinic culture and context, that act as barriers to humanizing patient care: 1) belief in the "ineluctable" commoditization of dentistry; 2) "equal treatment", a belief constraining concern for equity and the recognition of discriminatory practices; 3) a predominantly biomedical orientation to care; and 4) stereotypical categorization of publically insured patients into "deserving" vs. "non-deserving" poor. We discuss implications for oral health policy, orientations for dental education, as well as the role dental regulatory authorities should play in addressing discrimination and prejudice. Humanizing care and developing oral health practitioners' capacity to respond to social determinants of health, are challenged by significant ideological roadblocks. These require multi-level and multi-sectorial action if gains in social equity in oral health are to be made.

There were 11 cases of cervical vertebral malformation, four of equine degenerative myeloencephalopathy, two of equine protozoal myeloencephalitis, one each of vertebral osteomyelitis and intervertebral disc protrusion. The clinical diagnosis of ataxia in horses requires neurological, radiographic, myelographic, and laboratory examinations. ImagesFigure 1.Figure 2.Figure 3. PMID:17423438

[Building and teaching bioethics in French-speaking countries: at the crossroads of disciplines and practices].

PubMed

Godard, Béatrice; Moubé, Zéphirin

2013-01-01

It is inmportant to emphasize three aspects concerning the construction and teaching of 'French bioethics: the maintenance and promotion ofa multidisciplinary approach; a greater autonomy in the management and development of training programs; positioning a power of attraction and development in French-speaking countries. Bioethics is defined as a field of interdisciplinary studies at the junction of the health sciences and the humanities and, more importantly, directly connected to the reality of the health community, research and public Policy. A greater autonomy in the management and development of training programs is also capital. The danger of being dominated by one discipline involved whether medicine, law, philosophy, theology is real and prevents from promoting methodological approaches that are both theoretical and empirical. Finally, compliance with local and national, but also disciplinary diversity is essential to the construction and teaching of French bioethics. As such, the University of Montreal has positioned itself as a leader in the French-speaking countries: at the junction of North America and European countries, Quebec has developed its own specificity in bioethics, which is a force of attraction for many countries of the French-speaking world. In this context, the Bioethics Programs at the University of Montreal rely heavily on knowledge transfer to other cultures. Moreover, the internationalization of training programs in French bioethics is a major issue in the current context of globalization and transmission of knowledge.

ISS014-E-12686 (21 Jan. 2007) --- This wintry scene of Quebec Province in Canada was photographed by one of the Expedition 14 crew members aboard the Earth-orbiting International Space Station. In 1535 Jacques Cartier landed on an island in the St. Lawrence River and named a 233 meter-high mountain Mount Royal. Montreal is a city on that island that grew up around the mountain. The city of Montreal (near center frame) is located on the Ile de Montreal to the northwest of the St. Lawrence river (the wider body of water). It was not until 1642 that Ville Marie, founded by missionaries, would officially become the city of Montreal. The cityscape contrasts well with the farmland and natural forests in this summer view. Today Montreal is the largest city in the province of Quebec, and is the second most populous metropolitan area in Canada -- in 1991 the population was just more than one million in the city and 3,127,242 in the metropolitan area. While owing its early growth to the fur trade, the city is a leading producer of aircraft, chemical and pharmaceutical products, and is a major petroleum production center. Nearly half of Canada's .8 billion aerospace industry is located in the Montreal area.

An evaluation of the current radiative forcing benefit of the Montreal Protocol at the high-Alpine site Jungfraujoch.

2008-03-01

A combination of reconstructed histories, long-term time series and recent quasi-continuous observations of non-CO2 greenhouse gases at the high-Alpine site Jungfraujoch is used to assess their current global radiative forcing budget and the influence of regulations due to the Montreal Protocol on Substances that Deplete the Ozone Layer in terms of climate change. Extrapolated atmospheric greenhouse gases trends from 1989 assuming a business-as-usual scenario, i.e. no Montreal Protocol restriction, are presented and compared to the observations. The largest differences between hypothetical business-as-usual mixing ratios and current atmospheric observations over the last 16 years were found for chlorinated species, in particular methyl chloroform (CH3CCl3) at 167 to 203 ppt and chlorofluorocarbon-12 (CFC-12) at 121 to 254 ppt. These prevented increases were used to estimate the effects of their restrictions on the radiative forcing budget. The net direct effect due to the Montreal Protocol regulations reduces global warming and offsets about 14 to 30% of the positive greenhouse effect related to the major greenhouse gases CO2, CH4, N2O and also SF6, and about 12 to 22% of the hypothetical current radiative forcing increase without Montreal Protocol restrictions. Thus, the Montreal Protocol succeeded not only in reducing the atmospheric chlorine content in the atmosphere but also dampened global warming. Nevertheless, the Montreal Protocol controlled species still add to global warming.

Optimizing ChIP-seq peak detectors using visual labels and supervised machine learning.

Many peak detection algorithms have been proposed for ChIP-seq data analysis, but it is not obvious which algorithm and what parameters are optimal for any given dataset. In contrast, regions with and without obvious peaks can be easily labeled by visual inspection of aligned read counts in a genome browser. We propose a supervised machine learning approach for ChIP-seq data analysis, using labels that encode qualitative judgments about which genomic regions contain or do not contain peaks. The main idea is to manually label a small subset of the genome, and then learn a model that makes consistent peak predictions on the rest of the genome. We created 7 new histone mark datasets with 12 826 visually determined labels, and analyzed 3 existing transcription factor datasets. We observed that default peak detection parameters yield high false positive rates, which can be reduced by learning parameters using a relatively small training set of labeled data from the same experiment type. We also observed that labels from different people are highly consistent. Overall, these data indicate that our supervised labeling method is useful for quantitatively training and testing peak detection algorithms.

Impact of practice leadership management style on staff experience in services for people with intellectual disability and challenging behaviour: A further examination and partial replication.

PubMed

Deveau, Roy; McGill, Peter

2016-09-01

Practice leadership (PL) style of frontline management has been shown to be associated with better experiences for staff working with people who may exhibit challenging behaviours (Deveau & McGill, 2014). This study aimed to examine additional staff experience factors with a different, larger sample and to partially replicate the findings of (Deveau & McGill, 2014). This study was a survey of staff self-reported data collected as part of a larger study. Information was collected on PL and staff experiences of: stress, turnover, job satisfaction and positive work experiences. The results broadly supported Deveau and McGill (2014) and demonstrated an association between PL and greater job satisfaction and positive experiences for staff. Results on staff turnover were inconsistent. The positive impact of PL on staff experience was further supported by this study. Suggestions are made for further research. These findings suggest further research is needed to examine the potential of interventions in frontline management/leadership practice to improve staff experience of working in challenging environments.

Hypofractionated radiation therapy for prostate cancer: The McGill University Health Center experience.

PubMed

Barbosa Neto, O; Souhami, L; Faria, S

2015-10-01

In 2002, at the McGill University Health Centre, we began a program of hypofractionated radiotherapy for patients with low risk prostate cancer as an alternative to conventionally fractionated radiotherapy. Our initial hypofractionation regimen was 66 Gy given in 22 fractions, prescribed to the isocenter, delivered with 3D-conformal radiotherapy plan. The clinical target volume was the prostate gland and the planning target volume consisted of the clinical target volume plus a 7-mm margin in all directions. Hormonal therapy was not given to any patient. The long-term results for this group of patients confirmed the feasibility, good tolerance and excellent disease control of the regimen with the extra-benefit of being convenient to both patients and the health system by shortening treatment duration. The outcomes of this approach stimulated us to use hypofractionation in patients with intermediate-risk. Analysis of 100 intermediate-risk patients receiving our hypofractionated radiotherapy regimen (no hormones) shows, at median follow-up of 75 months, 8-year biochemical recurrence free and cancer specific survival rates of 90% and 95%, respectively, with acceptable toxicity. Our technique changed from 3D to intensity modulated radiotherapy with the dose adjusted to 60 Gy in 20 fractions. Lastly, we have expanded the program to high-risk patients where IMRT treatments are given to the pelvic nodes (44 Gy in 20 fractions) with a simultaneous integrated boost delivery to the prostate (60 Gy in the same 20 fractions). Our long-term results have shown that moderate hypofractionated radiotherapy for prostate cancer is safe and provides good tumor control comparable to high-dose conventionally fractionated radiotherapy. This hypofractionated regimen has been routinely used in our institution. Copyright © 2015 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS. All rights reserved.

An 8-week thoracic spine stabilization exercise program improves postural back pain, spine alignment, postural sway, and core endurance in university students:a randomized controlled study.

To investigate the effects of an 8-week thoracic stabilization exercise program on back pain, spinal alignment, postural sway, and core endurance in university students. University students were randomly allocated into exercise (n: 28) and control (n: 25) groups. The exercise program was carried out 3 days a week for 8 weeks. Postural pain, spinal alignment, postural sway, and core endurance were assessed via visual analogue scale, Spinal Mouse, Biodex Balance System, and McGill's trunk muscle endurance tests at the baseline and after 8 weeks of training. Differences were observed for postural pain, thoracic and lumbar curvature, dynamic stability index (eyes closed), and core endurance scores in the exercise group between baseline and week 8 (P < 0.05) and all the parameters were significantly different when compared to those of the control group (P < 0.05). The program decreased postural pain, spinal curvatures, and postural sway, and increased core endurance in university students. The program can be effective in postural pain and misalignment of spine problems related to core weakness and balance disorders.

The Montreal Protocol treaty and its illuminating history of science-policy decision-making

NASA Astrophysics Data System (ADS)

Grady, C.

2017-12-01

The Montreal Protocol on Substances that Deplete the Ozone Layer, hailed as one of the most effective environmental treaties of all time, has a thirty year history of science-policy decision-making. The partnership between Parties to the Montreal Protocol and its technical assessment panels serve as a basis for understanding successes and evaluating stumbles of global environmental decision-making. Real-world environmental treaty negotiations can be highly time-sensitive, politically motivated, and resource constrained thus scientists and policymakers alike are often unable to confront the uncertainties associated with the multitude of choices. The science-policy relationship built within the framework of the Montreal Protocol has helped constrain uncertainty and inform policy decisions but has also highlighted the limitations of the use of scientific understanding in political decision-making. This talk will describe the evolution of the scientist-policymaker relationship over the history of the Montreal Protocol. Examples will illustrate how the Montreal Protocol's technical panels inform decisions of the country governments and will characterize different approaches pursued by different countries with a particular focus on the recently adopted Kigali Amendment. In addition, this talk will take a deeper dive with an analysis of the historic technical panel assessments on estimating financial resources necessary to enable compliance to the Montreal Protocol compared to the political financial decisions made through the Protocol's Multilateral Fund replenishment negotiation process. Finally, this talk will describe the useful lessons and challenges from these interactions and how they may be applicable in other environmental management frameworks across multiple scales under changing climatic conditions.

While attending medical school at McGill, David Hubel developed an interest in the nervous system during the summers he spent at the Montreal Neurological Institute. After heading to the United States in 1954 for a Neurology year at Johns Hopkins, he was drafted by the army and was assigned to the Neuropsychiatry Division at the Walter Reed Hospital, where he began his career in research and did his first recordings from the visual cortex of sleeping and awake cats. In 1958, he moved to the lab of Stephen Kuffler at Johns Hopkins, where he began a long and fruitful collaboration with Torsten Wiesel. Born in Sweden, Torsten Wiesel began his scientific career at the Karolinska Institute, where he received his medical degree in 1954. After spending a year in Carl Gustaf Bernhard's laboratory doing basic neurophysiological research, he moved to the United States to be a postdoctoral fellow with Stephen Kuffler. It was at Johns Hopkins where he met David Hubel in 1958, and they began working together on exploring the receptive field properties of neurons in the visual cortex. Their collaboration continued until the late seventies. Hubel and Wiesel's work provided fundamental insight into information processing in the visual system and laid the foundation for the field of visual neuroscience. They have had many achievements, including--but not limited to--the discovery of orientation selectivity in visual cortex neurons and the characterization of the columnar organization of visual cortex through their discovery of orientation columns and ocular-dominance columns. Their work earned them the Nobel Prize for Physiology or Medicine in 1981, which they shared with Roger Sperry. Copyright © 2012 Elsevier Inc. All rights reserved.

Reliability and responsiveness of measures of pain in people with osteoarthritis of the knee: a psychometric evaluation

Abstract Purpose: To examine the fit between data from the Short Form McGill Pain Questionnaire (SF-MPQ-2) and the Rasch model, and to explore the reliability and internal responsiveness of measures of pain in people with knee osteoarthritis. Methods: Participants with knee osteoarthritis completed the SF-MPQ-2, Intermittent and Constant Osteoarthritis Pain questionnaire (ICOAP) and painDETECT. Participants were sent the same questionnaires 3 and 6 months later. Results: Fit to the Rasch model was not achieved for the SF-MPQ-2 Total scale. The Continuous subscale yielded adequate fit statistics after splitting item 10 on uniform DIF for gender, and removing item 9. The Intermittent subscale fit the Rasch model after rescoring items. The Neuropathic subscale had relatively good fit to the model. Test–retest reliability was satisfactory for most scales using both original and Rasch scoring ranging from fair to substantial. Effect sizes ranged from 0.13 to 1.79 indicating good internal responsiveness for most scales. Conclusions: These findings support the use of ICOAP subscales as reliable and responsive measure of pain in people with knee osteoarthritis. The MPQ-SF-2 subscales found to be acceptable alternatives. Implications for RehabilitationThe McGill Pain Questionnaire short version 2 is not a unidimensional scale in people with knee osteoarthritis, whereas three of the subscales are unidimensional.The McGill Pain Questionnaire short version 2 Affective subscale does not have good measurement properties for people with knee osteoarthritis.The McGill Pain Questionnaire short version 2 and the Intermittent and Constant Osteoarthritis Pain scales can be used to assess change over time.The painDETECT performs better as a screening measure than as an outcome measure.

[Issues, dilemmas and managerial strategies of potential ethical risks associated with the implementation of patient partnership practices in psychiatry: a case study].

In terms of health and social services, the territory of the province of Quebec is covered by four large 'integrated university health networks,' which are involved in the coordination of care delivery and medical training. The francophone components of the public mental health system for Montreal are thus primarily linked to the Integrated University Health Network of University of Montreal. In 2010, the Faculty of Medicine of the University of Montreal has included in its development strategy a firm commitment to the development and implementation of the 'patient partner expertise' in research, training and care in order to make this expertise no less than the brand of the Faculty. This commitment applies to all medical specialties that are taught at University of Montreal, including in psychiatry. More recently, the Institut universitaire en santé mentale de Montréal (IUSMM) has endorsed a new clinical vision that promotes full citizenship, which implies that service users and carers are considered as full partners with a specific expertise to be fully deployed. The objective of this paper is to examine, from an ethical point of view, the challenges that may be associated with involving such lay persons in various levels of mental health care planning and delivery, and in research. This study is mainly based on a review of the institutional processes that are in place at the IUSMM to promote service users' participation in care planning and delivery, and in research. The focus is on the practicalities and conditions for the exercise of such an active participation, as some questions and concerns emerged through a series of interviews with different stakeholders. These issues are addressed and discussed through the lenses of the ethical values that were formalized at IUSMM. Despite a firm institutional commitment at IUSMM to implement its new citizenship-oriented clinical vision through greater service users' involvement, little is known about the possible negative impacts of their participation, on themselves and for regular employees. There is a consensus on the symbolic value of recognizing the potential of service users as contributors, as a peer workers or peer research assistants. This is an historic advance compared to a time when they were considered only as more or less passive recipients of services or as a simple research subjects. Some risk factors were nonetheless identified: isolation, emotional fatigue, possible relapse, insecurity, sometimes tensed relations with health or research professionals and misunderstanding. In organizational terms, among the pitfalls, the study highlighted the need for more cautious preparatory steps, guidance and support for service users and for professionals as well, and the importance of a global and integrated governance strategy. This study points to three main recommendations to better anticipate and manage possible risks associated with more or less improvised service users' active participation, as lay persons, in complex planning and service delivery and in research. The first would be directed towards professionals for them to reflect on the quality of the doctor-patient relationship in their facility as to see how service users can help to improve this relationship, but among a variety of stakeholders and without being the sole responsible for such an improvement, or for the lack of improvement thereof. The second recommendation would propose to draw an objective evaluative assessment of participatory approaches at the organizational level, promoting a real return of experience and in light of the issues raised by these practices. The third would recommend an update of the organizational ethical values when introducing practices that change the current paradigms of the provision of care and services and of research.

Phenotypic evolution of Crohn's disease occurs in whites but has never been described in other populations. The Montreal classification may describe phenotypes more precisely. The aim of this study was to validate the Montreal classification through a longitudinal sensitivity analysis in detecting phenotypic variation compared to the Vienna classification. This was a retrospective longitudinal study of consecutive Chinese Crohn's disease patients. All cases were classified by the Montreal classification and the Vienna classification for behavior and location. The evolution of these characteristics and the need for surgery were evaluated. A total of 109 patients were recruited (median follow-up: 4 years, range: 6 months-18 years). Crohn's disease behavior changed 3 years after diagnosis (P = 0.025), with an increase in stricturing and penetrating phenotypes, as determined by the Montreal classification, but was only detected by the Vienna classification after 5 years (P = 0.015). Disease location remained stable on follow-up in both classifications. Thirty-four patients (31%) underwent major surgery during the follow-up period with the stricturing [P = 0.002; hazard ratio (HR): 3.3; 95% CI: 1.5-7.0] and penetrating (P = 0.03; HR: 5.8; 95% CI: 1.2-28.2) phenotypes according to the Montreal classification associated with the need for major surgery. In contrast, colonic disease was protective against a major operation (P = 0.02; HR: 0.3; 95% CI: 0.08-0.8). This is the first study demonstrating phenotypic evolution of Crohn's disease in a nonwhite population. The Montreal classification is more sensitive to behavior phenotypic changes than is the Vienna classification after excluding perianal disease from the penetrating disease category and was useful in predicting course and the need for surgery.

ISS026-E-012474 (24 Dec. 2010) --- A night view of the Montreal metropolitan area is featured in this image photographed by an Expedition 26 crew member on the International Space Station. This photograph of the Montreal, Quebec, Canada metropolitan area (center) illustrates the extent of urbanization made clearly visible by city lights at night. Major roadways and industrial areas are traced by bright white lighting, while the adjacent residential and commercial land uses are characterized by more diffuse yellow-gold lighting. Rivers and other water bodies appear black, while the surrounding rural countryside is faintly illuminated by moonlight. Blurry areas at top and bottom left are caused by cloud cover. Montreal is the largest city in the dominantly French-speaking Province of Quebec. The metropolitan area is the country?s second-largest, having been surpassed by Toronto in 1976. While the city of Montreal proper is located on?and almost completely covers?the Island of Montreal at the confluence of the St. Lawrence (center) and Ottawa Rivers (not visible), the city takes its name from Mont Royal located at the city?s center . Several smaller urban areas form a loose ring around the Montreal metro region: Sorel-Tracy, Saint-Hyacinthe, Saint-Jean-sur-Richelieu, Salaberry-de-Valleyfield, Saint-Jerome, and Joliette are among those that can be readily identified. The International Space Station was located over the Pennsylvania-New York border (near Warren, PA) at the time this image was taken?a ground distance of approximately 600 kilometers southwest of Montreal. This distance from the camera target, coupled with the oblique (inclined) viewing angle from the ISS, results in the foreshortened appearance of urban areas in the image.

The Montreal Cognitive Assessment is a brief and easy screening tool for accurately testing cognitive dysfunction in Parkinson's disease. We tested its validity for use in non-English (Malayalam) speaking patients with Parkinson's disease. We developed a Malayalam (a south-Indian language) version of Montreal Cognitive Assessment and applied to 70 patients with Parkinson's disease and 60 age- and education-matched healthy controls. Metric properties were assessed, and the scores were compared with the performance in validated Malayalam versions of Mini Mental Status Examination and Addenbrooke's Cognitive Examination. The Montreal Cognitive Assessment-Malayalam showed good internal consistency and test-retest reliability and its scores correlated with Mini Mental Status Examination (patients: R = 0.70; P < 0.001; healthy controls: R = 0.26; P = 0.04) and Addenbrooke's Cognitive Examination (patients: R = 0.8; P < 0.001; healthy controls: R = 0.52; P < 0.001) scores. This study establishes the reliability of cross-cultural adaptation of Montreal Cognitive Assessment for assessing cognition in Malayalam-speaking Parkinson's disease patients for early screening and potential future interventions for cognitive dysfunction.

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

2013-07-09

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. 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. 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. Funding supervised injection facilities in Montreal appears to be an efficient and effective use of financial resources in the public health domain.

Identifying cancer predisposition syndromes in children with tumors is crucial, yet few clinical guidelines exist to identify children at high risk of having germline mutations. The McGill Interactive Pediatric OncoGenetic Guidelines project aims to create a validated pediatric guideline in the form of a smartphone/tablet application using algorithms to process clinical data and help determine whether to refer a child for genetic assessment. This paper discusses the initial stages of the project, focusing on its overall structure, the methodology underpinning the algorithms, and the upcoming algorithm validation process. © 2017 Wiley Periodicals, Inc.

The objective of this paper is to describe Montreal's heat response plan and its application during the July 2010 heat wave. The Montreal heat response plan is designed to ensure the surveillance of weather and health indicators during the summer season and to coordinate actions to be undertaken during this period to reduce morbidity and mortality due to heat, particularly when weather thresholds are reached or an increase in health indicators is observed. It was developed to coordinate and apply intervention measures on the Island of Montreal and has been in effect since 2004. In the beginning of July 2010, Montreal experienced a heat wave that lasted 5 days. During this period, health indicators such as total mortality, prehospital emergency transports, calls to the health information line and hospital admissions were monitored by the Montreal public health surveillance system. The decision to implement emergency interventions and actions performed by regional and local public health and municipal partners (intervention level) was made following attainment of a predetermined weather threshold and increases in health indicators. The significant increase in daily observed mortality from all causes and in particular people dying at home or in the community prompted the Director of public health to conduct a chart review of all people deceased from July 5 to July 11, 2010 to determine cause of death and underlying health conditions. During the heat wave, there were 304 reported deaths from all causes in Montreal residents, of which 106 were probably or possibly heat-related. Major underlying health conditions in heat-related deaths included cardiovascular problems and mental health illness. Furthermore, in the case of people with mental illness who died during the heat wave, the chart review revealed that many were contacted 24 hours prior to their death by health care professionals, family members, neighbours or friends. Following the 2010 heat wave, the Montreal heat response plan and heat surveillance system were updated to include initiatives to better communicate preventive measures to the vulnerable populations and to intervene earlier during a heat wave.

Evacuated canisters have been used for many years to collect ambient air samples for gases and vapors. Recently, significant interest has arisen in using evacuated canisters for personal breathing zone sampling as an alternative to sorbent sampling. A novel flow control device was designed and built at McGill University. The flow control device was designed to provide a very low flow rate, <0.5 mL/min, to allow a sample to be collected over an extended period of time. Previous experiments run at McGill have shown agreement between the mathematical and empirical models to predict flow rate. The flow control device combined with an evacuated canister (capillary flow control-canister) was used in a series of experiments to evaluate its performance against charcoal tubes and diffusive badges. Air samples of six volatile organic compounds were simultaneously collected in a chamber using the capillary flow control-canister, charcoal tubes, and diffusive badges. Five different concentrations of the six volatile organic compounds were evaluated. The results from the three sampling devices were compared to each other and to concentration values obtained using an online gas chromatograph (GC). Eighty-four samples of each method were collected for each of the six chemicals. Results indicate that the capillary flow control-canister device compares quite favorably to the online GC and to the charcoal tubes, p > 0.05 for most of the tests. The capillary flow control-canister was found to be more accurate for the compounds evaluated, easier to use, and easier to analyze than charcoal tubes and passive dosimeter badges.

Hydrofluorocarbon (HFC) Scenarios, Climate Effects and the Montreal Protocol

Velders, G. J. M.; Fahey, D. W.; Daniel, J. S.

2016-12-01

The Montreal Protocol has reduced the use of ozone-depleting substances by more than 95% from its peak levels in the 1980s. As a direct result the use of hydrofluorocarbons (HFCs) as substitute compounds has increased significantly. National regulations to limit HFC use have been adopted recently in the European Union, Japan and USA, and four proposals have been submitted to amend the Montreal Protocol to substantially reduce growth in HFC use. The Parties of the Montreal Protocol have discussed these proposals during their meetings in 2016. The effects of the national regulations and Montreal Protocol amendment proposals on climate forcings and surface temperatures will be presented. 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. 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. Calculated baseline emissions are reduced by 90% in 2050 by implementing the North America Montreal Protocol amendment proposal. This corresponds to a reduction in surface temperature attributed to HFCs from 0.1 oC to 0.04 oC in 2050 and from 0.3-0.4 oC to 0.02 oC in 2100.

The Importance of the Montreal Protocol in Protecting the Earth's Hydroclimate

Seager, R.; Wu, Y.; Polvani, L. M.

2012-12-01

The 1987 Montreal Protocol regulating emissions of ozone depleting chlorofluorocarbons (CFCs) was motivated primarily by the harm to human health and ecosystems arising from increased exposure to ultraviolet-B (UV-B) radiation associated with depletion from the ozone layer. It is now known that the Montreal Protocol has reduced global warming since CFCs are greenhouse gases (GHGs). In this paper we show that the Montreal Protocol also significantly protects the Earth's hydroclimate, even though this was also not a motivating factor in the decision-making that led to the Protocol. General Circulation Model (GCM) results show that in the coming decade (2020-29), under the 'World Avoided' scenario of no regulations on CFC emissions, the subtropical dry zones would in general get drier, and the middle and high latitude regions wetter. This change is similar, in both pattern and magnitude, to that in the coming decade caused by projected increases in carbon dioxide concentrations. This implies that because of the Montreal Protocol, and the ozone depletion and global warming associated with CFCs thus avoided, the hydrological cycle changes in the coming decade will be significantly less than what they otherwise would have been.

To examine the mechanisms of injury for concussions in university football, ice hockey, and soccer. Prospective analysis. McGill University. All athletes participating in varsity football, ice hockey, and soccer. Athletes participating in university varsity football, ice hockey, and soccer were followed prospectively to determine the mechanisms of injury for concussions, whether certain mechanisms of injury causing concussions were more common in any of the three sports, whether different areas of the body seem to be more vulnerable to a concussion after contact, and whether these areas might be predisposed to higher grades of concussion after contact. There were 69 concussions in 60 athletes over a 3-year period. Being hit in the head or helmet was the most common mechanism of injury for all 3 sports. The side/temporal area of the head or helmet was the most probable area to be struck, resulting in concussion for both football and soccer. When examining the body part or object delivering the concussive blow, contact with another player's helmet was the most probable mechanism in football. The mechanisms of injury for concussions in football are similar to previously published research on professional football players. The mechanisms of injury for concussions in soccer are similar to past research on Australian rules football and rugby.

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

Yu, Keyan

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 include more information relative to lifelines and their impact on risks.

The importance of the Montreal Protocol in protecting climate.

The 1987 Montreal Protocol on Substances that Deplete the Ozone Layer is a landmark agreement that has successfully reduced the global production, consumption, and emissions of ozone-depleting substances (ODSs). ODSs are also greenhouse gases that contribute to the radiative forcing of climate change. Using historical ODSs emissions and scenarios of potential emissions, we show that the ODS contribution to radiative forcing most likely would have been much larger if the ODS link to stratospheric ozone depletion had not been recognized in 1974 and followed by a series of regulations. The climate protection already achieved by the Montreal Protocol alone is far larger than the reduction target of the first commitment period of the Kyoto Protocol. Additional climate benefits that are significant compared with the Kyoto Protocol reduction target could be achieved by actions under the Montreal Protocol, by managing the emissions of substitute fluorocarbon gases and/or implementing alternative gases with lower global warming potentials.

STS085-506-081 (7-19 August 1997) --- Montreal is a city on an island that grew up around the mountain -- in 1535 Jacques Cartier landed on an island in the St. Lawrence River and named a 233 meter-high mountain Mount Royal. It was not until 1642 that Ville Marie, founded by missionaries, would officially become the city of Montreal. The cityscape contrasts well with the farmland and natural forests in this summer view. Today Montreal is the largest city in the province of Quebec, and is the second most populous metropolitan area in Canada -- in 1991 the population was just more than one million in the city and 3,127,242 in the metropolitan area. While owing its early growth to the fur trade, the city is a leading producer of aircraft, chemical and pharmaceutical products, and is a major petroleum production center. Nearly half of Canada's .8 billion aerospace industry is located in the Montreal area. In the image captured by the astronauts, the lighter blue, wide river is the St. Lawrence. The city of Montreal is located on the Ile de Montreal to the northwest of the St. Lawrence river. The Ottawa River enters the St. Lawrence near the center of the view. Mirabel International Airport stands out well, on the north side of the city. The long, narrow strips of land in the image are indicative of French agricultural land use. The narrow ends of farmlands are oriented perpendicular to rivers so that more farmers will have access to water resources.

Over their lifecourse, young adults develop different skills and preferences in relationship to the information sources they seek when having questions about health. Health information seeking behaviour (HISB) includes multiple, unequally accessed sources; yet most studies have focused on single sources and did not examine HISB's association with social inequalities. This study explores 'multiple-source' profiles and their association with socioeconomic characteristics. We analyzed cross-sectional data from the Interdisciplinary Study of Inequalities in Smoking involving 2093 young adults recruited in Montreal, Canada, in 2011-2012. We used latent class analysis to create profiles based on responses to questions regarding whether participants sought health professionals, family, friends or the Internet when having questions about health. Using multinomial logistic regression, we examined the associations between profiles and economic, social and cultural capital indicators: financial difficulties and transportation means, friend satisfaction and network size, and individual, mother's, and father's education. Five profiles were found: 'all sources' (42%), 'health professional centred' (29%), 'family only' (14%), 'Internet centred' (14%) and 'no sources' (2%). Participants with a larger social network and higher friend satisfaction were more likely to be in the 'all sources' group. Participants who experienced financial difficulties and completed college/university were less likely to be in the 'family only' group; those whose mother had completed college/university were more likely to be in this group. Our findings point to the importance of considering multiple sources to study HISB, especially when the capacity to seek multiple sources is unequally distributed. Scholars should acknowledge HISB's implications for health inequalities.

After leaving Chile during the Pinochet era, Dr Morales studied economics, health administration and international health at the University of Montreal. But his baptism in the field came in Haiti, where he was first PAHO advisor to the health ministry, and then for five years was responsible for human resources and health economics in the PAHO offices in the capital of Port-au-Prince. He was at his post during the flooding in Gonaïves, five hurricanes, the 2010 earthquake and the ensuing cholera epidemic-doubtless the most dramatic and complex times for the country's health in recent history. Before becoming the PAHO/WHO Representative in Cuba in 2015, he was Regional Advisor in Financing and Health Economics based in Washington, DC. In that role, he plunged into the often thorny debates about just how far governments of the Americas were willing to go towards achieving universal health-universal coverage plus universal access. The result was a historic resolution passed in late 2014 by PAHO's Directing Council (CD53.R14 Strategy for Universal Access to Health and Universal Health Coverage). Dr Morales talks about the process, the outcomes… and the road ahead.

Objective: To evaluate the effects of acupuncture branches on postpartum low back pain severity among the primiparous subjects visiting the selected educational centers affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. Materials and methods: This clinical trial was conducted on 150 (each group of 50 people) cases in 2012. Cupping therapy was done every other day in four 15-20 minute sessions a week. Besides, acupressure was applied according to the circular model for 20 minutes. The patients filled out the short form McGill Pain Questionnaires. Then, the data were analyzed using the SPSS statistical software (v. 16) and repeated measurements and Chi-square tests. Results: In the cupping group, the mean difference of postpartum Low Back Pain intensity reached from 31.8 ± 10.8 before the intervention to 9.0 ± 6.7, 7.5 ± 6.6, and 4.1 ± 3.6 immediately, 24 hours, and 2 weeks after the intervention, respectively and the results of repeated measures ANOVA showed a significant difference between the three follow-up periods (p < 0.05). On the other hand, this measure reached from 31.1 ± 11.0 before the intervention to 22.1 ± 7.3, 16.2±6.0, and 11.7 ± 5.3 immediately, 24 hours, and 2 weeks after the intervention, respectively in the acupressure group. Conclusion: The study results showed that these modalities could sedate the pain. Therefore, they can be applied as efficient treatments for reducing the low back pain. PMID:29282415

Supervision is a pillar in enhancing the student's learning environment throughout her/his higher education. Multiple studies qualify graduate supervision among the most important contributors to the successful completion of a higher education degree and to graduate students' positive academic experience. The aim of this study was to assess the views of graduate students enrolled in the Dental Sciences and Craniofacial Research Graduate Programs at McGill University (n = 64) regarding the quality of supervision they are receiving. An online questionnaire composed of 22 open and closed-ended format items was used and covered five domains: student profile, supervisory relationship, conflict resolution, student progress/thesis writing and career development. Descriptive statistics, chi-square tests and interpretative qualitative analysis were used to evaluate students' perspectives. Fifty-nine students completed the survey (92.2%). The distribution of sample in regard to the graduate student level was almost identical (M.Sc. level n = 28, Ph.D. n = 31). Overall, most graduate students appeared satisfied with the supervision they received and had similar perspectives about the surveyed domains. There was one statistically significant difference (P < 0.05) between MSc and PhD students when asked if their supervisors aided them in career development outside the supervisory relationship, where 77.4% (n = 24) of doctoral students agreed as opposed to 21.4% (n = 12) of Masters' students. Our results showed that McGill graduate students appeared to be overall satisfied with the supervision they received. The main elements contributing to a positive supervision experience were support, guidance, availability and good communication between supervisees and supervisors. © 2015 John Wiley & Sons A/S.

Montreal Protocol: The Gift that Keeps on Giving

NASA Astrophysics Data System (ADS)

Reifsnyder, D. A.

2012-12-01

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 be followed by developing countries. The question was, could we do it? And if we could, how could we get others developed countries and then developing countries on side? After our internal discussions, State and EPA convened a workshop with U.S. stakeholders from the private sector and the environmental community. To our delight, both groups thought the United States should take the initiative. In retrospect, the winds were favorable - 2007 marked the 25th Anniversary of the Montreal Protocol and many wanted to celebrate it with something significant. The private sector felt that it could meet an accelerated timetable for phasing out HCFCs - the technology was there. It was also clear that money in the Montreal Protocol Multilateral Fund had begun to decline with the developing country phaseout of CFCs and would decline even more steeply unless a new basis were found to continue it. But favorable winds do not always make for a smooth sail - and path to the accelerated phaseouts of 2007 proved challenging. At the time, practically no one thought the effort would succeed. Still, we did succeed. Yet even then it took time to for many to appreciate the significant benefits for the climate system, beyond the benefits to the stratospheric ozone layer. In fact, the continuing story of the Montreal Protocol is one of the gift that keeps on giving.

Using mean Montreal Cognitive Assessment score of subjects with Grade 1 calcifications (23.1 ± 4.2) as the referent category, fully adjusted generalized linear models showed significant associations between severity of carotid siphon calcifications and cognitive performance (mean Montreal Cognitive Assessment scores: 20.2 ± 4.8 for Grade 2 (p = 0.004), 19.7 ± 5.3 for Grade 3 (p = 0.0001), and 18.8 ± 4.1 for Grade 4 (p = 0.02)). Predictive Montreal Cognitive Assessment score margins were higher in individuals with Grade 1 calcifications than in other groups. This study shows an inverse relationship between calcium content in the carotid siphon and cognitive performance in Amerindians.

Contaminant exposure in Montrealers of Asian origin fishing the St. Lawrence River: Exploratory assessment

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.more » 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.« less

From gene to protein: A 3-week intensive course in molecular biology for physical scientists.

Nadeau, Jay L

2009-07-01

This article describes a 3-week intensive molecular biology methods course based upon fluorescent proteins, which is successfully taught at the McGill University to advanced undergraduates and graduates in physics, chemical engineering, biomedical engineering, and medicine. No previous knowledge of biological terminology or methods is expected, so the material could readily be adapted to earlier undergraduates or students in other fields. The course emphasizes hands-on experience with one half-hour of lecture and 3 and a half hours of laboratory 4 days per week, for a total of 39 hours. The materials are simple and low in cost and all software used is free, making the budget accessible to small universities and community colleges that possess basic teaching wet labs. Conceptual understanding is reinforced with lab reports and an independent final paper on a subject of the student's choice. The final paper describes a possible thesis project, not necessarily the student's own, with assessment based upon grasping of key concepts and methods of molecular biology.

Stewart, Miriam J; Kushner, Kaysi Eastlick

2014-03-01

In 2002 the Canadian Institutes of Health Research launched a national initiative to promote health equity research reflecting the World Health Organization imperative of investment in health equity research. Funded researchers and teams have investigated health disparities faced by vulnerable populations, analyzed interactions of health determinants, and tested innovative interventions. Strategies for building research capacity have supported students, postdoctoral fellows, new investigators, and interdisciplinary research teams. Partnerships have been created with 10 national and 7 international organizations. Strategies used to secure and sustain this research initiative could be adapted to other contexts. Nurse scholars led the launch and have sustained the legacy of this national research initiative. Moreover, nurse researchers and research trainees, supported by the initiative, have contributed to the expansion and translation of the health equity knowledge base.

Design principles of a cooperative robot controller

NASA Technical Reports Server (NTRS)

Hayward, Vincent; Hayati, Samad

1987-01-01

The paper describes the design of a controller for cooperative robots being designed at McGill University in a collaborative effort with the Jet Propulsion Laboratory. The first part of the paper discusses the background and motivation for multiple arm control. Then, a set of programming primitives, which are based on the RCCL system and which permit a programmer to specify cooperative tasks are described. The first group of primitives are motion primitives which specify asynchronous motions, master/slave motions, and cooperative motions. In the context of cooperative robots, trajectory generation issues will be discussed and the implementation described. A second set of primitives provides for the specification of spatial relationships. The relations between programming and control in the case of multiple robot are examined. Finally, the paper describes the allocation of various tasks among a set of microprocessors sharing a common bus.

Low-level laser therapy to treat fibromyalgia.

PubMed

Ruaro, J A; Fréz, A R; Ruaro, M B; Nicolau, R A

2014-11-01

Several clinical treatments have been proposed to manage symptoms of fibromyalgia. Low-level laser therapy (LLLT) may be a useful tool to treat this dysfunction. The aim of this study was to evaluate the effects of LLLT in patients with fibromyalgia. A placebo-controlled, randomized clinical trial was carried out with 20 patients divided randomly into either an LLLT group (n = 10) or a placebo group (n = 10). The LLLT group was treated with a GaAlAs laser (670 nm, 4 J/cm(2) on 18 tender points) three times a week over 4 weeks. Before and after treatment, patients were evaluated with the Fibromyalgia Impact Questionnaire (FIQ), McGill Pain Questionnaire, and visual analog scale (VAS). Data from the FIQ and McGill questionnaire for the treated and control groups were analyzed by paired t tests, and Wilcoxon tests were used to analyze data from the VAS. After LLLT or sham treatment, the number of tender points was significantly reduced in both groups (LLLT, p < 0.0001; placebo, p = 0.0001). However, all other fibromyalgia symptoms showed significant improvements after LLLT compared to placebo (FIQ, p = 0.0003; McGill, p = 0.0078; and VAS, p = 0.0020). LLLT provided relief from fibromyalgia symptoms in patients and should be further investigated as a therapeutic tool for management in fibromyalgia.

In order to make mental health services more accessible, the Tunisian Ministry of Health, in collaboration with the School of Public Health at the University of Montreal, the World Health Organization office in Tunisia and the Montreal World Health Organization-Pan American Health Organization Collaborating Center for Research and Training in Mental Health, implemented a training programme based on the Mental Health Gap Action Programme (mhGAP) Intervention Guide (IG) (version 1.0) , developed by the World Health Organization. This article describes the phase prior to the implementation of the training, which was offered to general practitioners working in primary care settings in the Greater Tunis area of Tunisia. The phase prior to implementation consisted of adapting the standard mhGAP-IG (version 1.0) to the local primary healthcare context. This adaptation process, an essential step before piloting the training, involved discussions with stakeholder groups, as well as field observations. Through the adaptation process, we were able to make changes to the standard training format and material. In addition, the process helped uncover systemic barriers to effective mental health care. Targeting these barriers in addition to implementing a training programme may help reduce the mental health treatment gap, and promote implementation that is successful and sustainable.

There is growing concern about understanding how sociodemographic variables may interfere with cognitive functioning, especially with regard to language. This study aimed to investigate the relationship between performance in the Brazilian version of the Montreal-Toulouse language assessment battery (MTL-BR) and education, age and frequency of reading and writing habits (FRWH). Cross-sectional study conducted in university and work environments in Rio Grande do Sul, Brazil. The MTL-BR was administered to a group of 233 healthy adults, aged 19 to 75 years (mean = 45.04, standard deviation, SD = 15.47), with at least five years of formal education (mean = 11.47, SD = 4.77). A stepwise multiple linear regression model showed that, for most tasks, the number of years of education, age and FRWH were better predictors of performance when analyzed together rather than separately. In separate analysis, education was the best predictor of performance in language tasks, especially those involving reading and writing abilities. The results suggested that the number of years of education, age and FRWH seem to influence performance in the MTL-BR, especially education. These data are important for making diagnoses of greater precision among patients suffering from brain injuries, with the aim of avoiding false positives.

Occupational and environmental exposure of automobile mechanics and nonautomotive workers to airborne manganese arising from the combustion of methylcyclopentadienyl manganese tricarbonyl (MMT).

Sierra, P; Loranger, S; Kennedy, G; Zayed, J

1995-07-01

Inhalation exposure to manganese (Mn) was measured for a group of garage mechanics and a control group of nonautomotive workers. The airborne Mn exposure of 35 garage mechanics suspected of being relatively highly exposed to Mn from MMT was measured at the workplace over one-week period. It also was measured for 30 nonautomotive workers at the University of Montreal. The environmental exposure also was measured for the two groups, as was the exposure to three other metals, aluminum (Al), iron (Fe), and zinc (Zn). At work the mechanics were exposed to Mn concentrations varying from 0.010 to 6.673 micrograms m-3 with a mean of 0.45 microgram m-5, while the control group was exposed to concentrations varying from 0.011 to 1.862 microgram m-3 with a mean of 0.04 microgram m-3. The mean environmental exposure for the two groups was similar to the Mn concentrations gathered in Montreal in 1992. Workplace concentrations of Al, Fe, and Zn also were higher for the garage mechanics. The results suggest that less than 10% of the Mn exposure of the garage mechanics was due to MMT. The levels of the metals measured were below the established limits for industrial and even environmental exposure.

The Montreal Neurological Institute: training of the first African-American neurosurgeons.

McClelland, Shearwood

2007-01-01

BACKGROUND: Since its inception in 1934 by the legendary Dr. Wilder Penfield, the Montreal Neurological Institute (MNI) has provided world-renowned instruction in neurosurgery and related neurosciences, training many of the most prominent figures in the history of neurosurgery. Less well known is the role of the MNI in training the first African-American board-certified neurosurgeons. METHODS: A comprehensive review of pertinent modern and historical records spanning the past century was performed. RESULTS: From 1947-1965, the MNI trained the first African-American board-certified neurosurgeon, and three of the first four. The first, Dr. Clarence Greene, Sr., trained at MNI from 1947-1949. The next, Dr. Jesse Barber, Jr., trained at MNI from 1958-1961. Like Greene, Barber received his MD from the Howard University College of Medicine, was on the general surgery faculty at Howard before training at MNI under Penfield and returned to Howard following his training. The third, Dr. Lloyd Dayes, matriculated at MNI in 1960 after receiving his MD from the Loma Linda University School of Medicine and trained from 1961-1965 under Dr. Theodore Rasmussen, after which he returned to Loma Linda. Greene, Barber and Dayes were certified by the American Board of Neurological Surgery in 1953, 1963 and 1967, respectively, as the first, third and fourth African-American neurosurgeons. CONCLUSION: The willingness of the world-renowned MNI to train the first African-American neurosurgeons during a time of intense racial segregation in the United States played a major role in enabling subsequent African Americans to enter and enhance the field of neurosurgery.

Health workers' perceptions of access to care for children and pregnant women with precarious immigration status: health as a right or a privilege?

The Canadian government's recent cuts to healthcare coverage for refugee claimants has rekindled the debate in Canada about what medical services should be provided to individuals with precarious immigration status, and who should pay for these services. This article further explores this debate, focussing on the perceptions of healthcare workers in Montreal, a large multiethnic Canadian city. In April-June 2010, an online survey was conducted to assess how clinicians, administrators, and support staff in Montreal contend with the ethical and professional dilemmas raised by the issue of access to healthcare services for pregnant women and children who are partially or completely uninsured. Drawing on qualitative analysis of answers (n = 237) to three open-ended survey questions, we identify the discursive frameworks that our respondents mobilized when arguing for, or against, universal access to healthcare for uninsured patients. In doing so, we highlight how their positions relate to their self-evaluations of Canada's socioeconomic situation, as well as their ideological representations of, and sense of social connection to, precarious status immigrants. Interestingly, while abstract values lead some healthcare workers to perceive uninsured immigrants as "deserving" of universal access to healthcare, negative perceptions of these migrants, coupled with pragmatic considerations, pushed most workers to view the uninsured as "underserving" of free care. For a majority of our respondents, the right to healthcare of precarious status immigrants has become a "privilege", that as taxpayers, they are increasingly less willing to contribute to. We conclude by arguing for a reconsideration of access to healthcare as a right, and offer recommendations to move in this direction. Copyright © 2013 Elsevier Ltd. All rights reserved.

Vera, Alonso

2017-01-01

In the development of intelligent systems that interact with humans, there is often confusion between how the system functions with respect to the humans it interacts with and how it interfaces with those humans. The former is a much deeper challenge than the latter it requires a system-level understanding of evolving human roles as well as an understanding of what humans need to know (and when) in order to perform their tasks. This talk will focus on some of the challenges in getting this right as well as on the type of research and development that results in successful human-autonomy teaming. Brief Bio: Dr. Alonso Vera is Chief of the Human Systems Integration Division at NASA Ames Research Center. His expertise is in human-computer interaction, information systems, artificial intelligence, and computational human performance modeling. He has led the design, development and deployment of mission software systems across NASA robotic and human space flight missions, including Mars Exploration Rovers, Phoenix Mars Lander, ISS, Constellation, and Exploration Systems. Dr. Vera received a Bachelor of Science with First Class Honors from McGill University in 1985 and a Ph.D. from Cornell University in 1991. He went on to a Post-Doctoral Fellowship in the School of Computer Science at Carnegie Mellon University from 1990-93.

UV Impacts Avoided by the Montreal Protocol

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.

Purpose To determine the factorial validity, internal consistency, criterion-related and concurrent validity of the Perception of Quality of Rehabilitation Services - Montreal (PQRS-Montreal) questionnaire for persons receiving traumatic brain injury (TBI) rehabilitation services. Design Cross-sectional study. Setting Seventeen facilities providing acute care and intensive inpatient and outpatient TBI adult rehabilitation. Participants Five-hundred thirty adults (GCS  =  3-15; mean age  =  41.5 ± 16.9 years) who received rehabilitation were administered the questionnaire during an interview near time of discharge. Subjects responded to the 61 PQRS-Montreal items (five-point scale of agreement) and to the Client Satisfaction Question (CSQ8). Results Exploratory and confirmatory factor analyses identified three potential subscales (one- and two-factor solutions) explaining 26.1-41% of the variance (ecological approach, quality of team, service organization). The subscales' internal structures were interpretable and their internal consistency varied from 0.51 to 0.90 (Cronbach's α). Rehabilitation phase significantly and positively impacted factor scores and all factor scores were significantly and moderately correlated with CSQ8 scores. Conclusions The PQRS-Montreal possesses adequate psychometric properties supporting its use as a valid tool to measure patients' perception of the quality of TBI rehabilitation services. This tool could help guide the development and monitoring of TBI rehabilitation service delivery. Implications for Rehabilitation The importance of measuring and monitoring quality of care is increasingly important in rehabilitation. Using the experiences and perceptions of care of service users is a valid way of assessing the quality of rehabilitation services. The PQRS-Montreal has adequate psychometric properties supporting its use as a valid tool to measure patients' perception of the quality of TBI rehabilitation services. This tool could help guide the development and monitoring of TBI rehabilitation service delivery.

Can anchor models explain inverted-U effects in facial judgments?

PubMed

Mignault, Alain; Bhaumik, Arijit; Chaudhuri, Avi

2009-06-01

Researchers in a variety of disciplines have found that participants take less time and generate less diversity of responses when judging stimuli towards the ends of a scale than when judging those near the center. Three types of models, connectionist, exemplar, and anchor models, can account for these inverted-U effects. Anchor models assume that stimuli near the ends of the scale are used as anchors to compare with the other stimuli, implying that anchor representations are activated for each judgment. Therefore, participants should learn the anchors better than the other stimuli. Participants were 40 students from the Department of Psychology at McGill University (5 men; M age = 20.5 yr.; SD = 1.7). The experiment involved two tasks: first participants judged facial gender and then performed a recognition task. The results showed no correlation between the position on the gender scale and recognition accuracy. Several hypotheses were offered to explain these results.

Recent releases of genome three-dimensional (3D) structures have the potential to transform our understanding of genomes. Nonetheless, the storage technology and visualization tools need to evolve to offer to the scientific community fast and convenient access to these data. We introduce simultaneously a database system to store and query 3D genomic data (3DBG), and a 3D genome browser to visualize and explore 3D genome structures (3DGB). We benchmark 3DBG against state-of-the-art systems and demonstrate that it is faster than previous solutions, and importantly gracefully scales with the size of data. We also illustrate the usefulness of our 3D genome Web browser to explore human genome structures. The 3D genome browser is available at http://3dgb.cs.mcgill.ca/. © The Author(s) 2015.

The authors use inductive analysis of empirical data to explain how (1) nursing work is organized, structured, and circumscribed by centrally determined policies and practices that downplay nurses' professional judgement about patient care; (2) power is held over nurses in their relationship with their manager; and (3) nurses' response to power is to engage in strategies of resistance. The authors illustrate how power influences relations between staff nurses and managers and provide a critical analysis of the strategies of resistance that result in personal, relational, and critical empowerment among staff nurses. Through resistance, staff nurses engage in alternative discourses to counteract the prevailing neoliberal organizational and managerial discourses of efficiency and cost-effectiveness.

Fitting Square Pegs into round Holes: Doing Qualitative Nursing Research in a Quantitative World.

PubMed

Newton, Lorelei; Kimpson, Sally

2014-09-01

The authors, as doctoral candidates and registered nurses, took on a qualitative research project investigating nursing practice in a research-intensive organization. Their aims were to explore and describe how nurses in the ambulatory care setting assist patients and families, including how nursing practice was carried out, constraints to practice, and the influence of the interprofessional milieu. Their first finding, in part because of the qualitative research design used, concerned the potential impact of the organizational ethics review process on the project. The authors discuss how the language, definition of risk, and notion of informed consent articulated in the organizational review process influenced both the research timeline and (potentially) the study itself. While not dismissing the value of ethics review, they explore the tension of overlaying generic criteria for quantitative research, specifically randomized controlled trials, on nursing research from other traditions.

Guidelines regarding antiretroviral therapy (ART) initiation in HIV infection have varied over time, with the 2015 World Health Organization recommendation suggesting ART initiation at the time of diagnosis regardless of CD4 T-cell counts. Herein, we investigated the influence of socio-demographic and clinical factors in addition to time trends on early ART initiation among participants of the Montreal Primary HIV Infection Study. The Montreal Primary HIV Infection Study is a prospective cohort established in three community medical centres (CMCs) and two university medical centres (UMCs). Recently diagnosed HIV-infected adults were categorized as receiving early (vs. delayed) ART if ART was initiated within 180 days of the baseline visit. Associations between early ART initiation and socio-demographic, socio-economic and behavioural information were examined. Independent associations of factors linked with early ART initiation were determined using multivariable binary logistic regression analysis. A total of 348 participants had a documented date of HIV acquisition of <180 days. The median interquartile range (IQR) age of participants was 35 (28; 42) years and the majority were male (96%), having paid employment (63%), men who have sex with men (MSM) (78%) and one to four sexual partners in the last three months (70%). Participants presented with a median IQR HIV plasma viral load of 4.6 (3.7; 5.3) log 10 copies/ml, CD4 count of 510 (387; 660) cells/μl and were recruited in CMCs (52%) or UMCs (48%). Early ART initiation was observed in 47% of the participants and the trend followed a V-shaped curve with peaks in 1996 to 1997 (89%) and 2013 to 2015 (88%) with a dip in 2007 to 2009 (22%). Multivariable analyses showed that having a paid employment adjusted odds ratio (aOR: 2.43; 95% CI: 1.19, 4.95), lower CD4 count (aOR per 50 cell increase: 0.93; 95% CI: 0.87, 0.99) and care at UMCs (aOR: 2.03; 95% CI: 1.06 to 3.90) were independently associated with early ART initiation. Early ART initiation during primary HIV infection was associated with diminished biological prognostic factors and calendar time mirroring evolution of treatment guidelines. In addition, socio-economic factors such as having a paid employment, contribute to early ART initiation in the context of universal access to care in Canada. © 2018 The Authors.

New Regional and Global HFC Projections and Effects of National Regulations and Montreal Protocol Amendment Proposals

NASA Astrophysics Data System (ADS)

Velders, G. J. M.

2015-12-01

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.

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.

Human rights from the grassroots up: Vermont's campaign for universal health care.

PubMed

McGill, Mariah

2012-06-15

In 2008, the Vermont Workers' Center launched the "Healthcare Is a Human Right Campaign," a grassroots campaign to secure the creation of a universal health care system in Vermont. Campaign organizers used a human rights framework to mobilize thousands of voters in support of universal health care. In response to this extraordinary grassroots effort, the state legislature passed health care legislation that incorporates human rights principles into Vermont law and provides a framework for universal health care. The United States has often lagged behind other nations in recognizing economic, social, and cultural (ESC) rights, including the right to health. Nonetheless, activists have begun to incorporate ESC rights into domestic advocacy campaigns, and state and local governments are beginning to respond where the federal government has not. Vermont serves as a powerful example of how a human rights framework can inform health care policy and inspire grassroots campaigns in the United States. This three-part article documents the Vermont Workers' Center campaign and discusses the impact that human rights activity at the grassroots level may have on attitudes towards ESC rights in the United States. The first part describes the Vermont health care crisis and explains why the center adopted international human rights principles for their campaign. The article then goes on to discuss the three-year campaign and analyze the health care reform bill that the Vermont legislature passed. Finally, the article discusses the campaign's local and national impact. Copyright © 2012 McGill.

The Impact of Human Rights on Universalizing Health Care in Vermont, USA.

MacNaughton, Gillian; Haigh, Fiona; McGill, Mariah; Koutsioumpas, Konstantinos; Sprague, Courtney

2015-12-10

In 2010, Vermont adopted a new law embracing human rights principles as guidelines for health care reform, and in 2011, Vermont was the first state in the US to enact framework legislation to establish a universal health care system for all its residents. This article reports on the Vermont Workers' Center's human rights-based approach to universal health care and the extent to which this approach influenced decision makers. We found the following: (1) by learning about the human right to health care and sharing experiences, Vermonters were motivated to demand universal health care; (2) mobilizing Vermonters around a unified message on the right to health care made universal health care politically important; (3) using the human rights framework to assess new proposals enabled the Vermont Workers' Center to respond quickly to new policy proposals; (4) framing health care as a human right provided an alternative to the dominant economics-based discourse; and (5) while economics continues to dominate discussions among Vermont leaders, both legislative committees on health care use the human rights principles as guiding norms for health care reform. Importantly, the principles have empowered Vermonters by giving them more voice in policymaking and have been internalized by legislators as democratic principles of governance.

Did the Moon have a dipolar field?

Did the Moon have a dipolar core field? Daniel Boutin1 (dboutin003@sympatico.ca) Jafar Arkani-Hamed2 (jafar@physics.utoronto.ca) 1Earth and Planetary Sciences, McGill University, Montreal, QC, H3A-2A7, Canada 2Physics, University of Toronto, Toronto, ON M5S 1A7, Canada The lack of a global scale magnetic field at present and the observed strong magnetic anomalies of the Moon suggest that the magnetic source bodies have been magnetized in the past. The origin of the magnetizing field is poorly understood. Several scenarios have been proposed including a strong core dynamo [1] and the external origin due to giant impacts such as the enhancement of an existing weak field by impact-generated plasmas or a transient field possibly generated during the impacts [2,3]. It is also possible that the existing field was not very strong but the source bodies are highly magnetic [4]. Here we test the hypothesis that the magnetizing field was of internal origin using two sets of data: the 150 degree spherical harmonic representation of the lunar crustal field by Purucker [5] and the raw magnetic data acquired by the Lunar Prospector magnetometer. Although 17 isolated magnetic anomalies are easily identified on the basis of the spherical harmonic representation, we model only 10 anomalies because of the lack of sufficient raw data over others. The isolated magnetic anomalies allow us to model each anomaly by a simple uniformly magnetized elliptical source body. We model the radial component of the magnetic field following the procedure adopted by Boutin and Arkani-Hamed [6] for the martian magnetic anomalies, and determine the three components of the magnetization vector. Seven out of 10 anomalies result in consistent source bodies obtained using the two sets of data. Assuming that each of the source bodies is magnetized by a dipole core field, the paleomagnetic pole of the Moon is determined on the basis of the corresponding magnetization vector. The resulting paleomagnetic pole positions do not show any significant clustering. There is a general agreement between some of our pole positions with those reported by Wieczorek and Weiss [7]. The lack of consistent dipolar core field is probably due to (1) the core field was not dominated by the dipole component, or (2) the core field was mainly dipolar but there has been appreciable true polar wander during the time the source bodies acquired magnetization, or (3) the magnetizing field was not of internal origin. Further investigations are required to identify the characteristics of the magnetizing field. [1] D. R. Stegman, D.R., et al., Nature 421, 143, 2003. [2] Hood, L. And Z. Huang, J. Geophys.

The consortium universities will exchange students and faculty in several engineering and science disciplines (e.g. environmental engineering, civil engineering, geological engineering, social sciences and geology) involved in the study of natural geological hazards. Students in the social sciences also will be exchanged, recognizing that the solution of natural hazards problems involves critical political, social, and economic aspects. Students will be mobilized among the participating universities through one- to two-semester visits and up to 60 more students will be mobilized via short-term, intensive courses. Student activities will consist of three stages: intensive language training, natural hazards coursework, and professional or research internships with local industries, agencies or at the host university. In each of the next three years there will be a joint advanced volcanology class run via videoconferencing and a three week field trip to areas of volcanological interest in Canada, US and Mexico. The course and field trip foci for the next three years are: 2006: Megaeruptions/ LongValley and Yellowstone; 2007: Volcanic edifice failure/ Cascades and Western Canada 2008: Convergent plate Boundary Volcanism/ Mexican Volcanic Belt Although the six universities will have first access to the exchange we are constructing ways for other volcanology programs to share the teleconference courses and field trips.

Since public transit infrastructure affects road traffic volumes and influences transportation mode choice, which in turn impacts health, it is important to estimate the alteration of the health burden linked with transit policies. We quantified the variation in health benefits and burden between a business as usual (BAU) and a public transit (PT) scenarios in 2031 (with 8 and 19 new subway and train stations) for the greater Montreal region. Using mode choice and traffic assignment models, we predicted the transportation mode choice and traffic assignment on the road network. Subsequently, we estimated the distance travelled in each municipality by mode, the minutes spent in active transportation, as well as traffic emissions. Thereafter we estimated the health burden attributed to air pollution and road traumas and the gains associated with active transportation for both the BAU and PT scenarios. We predicted a slight decrease of overall trips and kilometers travelled by car as well as an increase of active transportation for the PT in 2031 vs the BAU. Our analysis shows that new infrastructure will reduce the overall burden of transportation by 2.5 DALYs per 100,000 persons. This decrease is caused by the reduction of road traumas occurring in the inner suburbs and central Montreal region as well as gains in active transportation in the inner suburbs. Based on the results of our study, transportation planned public transit projects for Montreal are unlikely to reduce drastically the burden of disease attributable to road vehicles and infrastructures in the Montreal region. The impact of the planned transportation infrastructures seems to be very low and localized mainly in the areas where new public transit stations are planned. Copyright © 2017 Elsevier Inc.

Tuberculosis and homelessness in Montreal: a retrospective cohort study

PubMed Central

2011-01-01

Background Montreal is Canada's second-largest city, where mean annual tuberculosis (TB) incidence from 1996 to 2007 was 8.9/100,000. The objectives of this study were to describe the epidemiology of TB among homeless persons in Montreal and assess patterns of transmission and sharing of key locations. Methods We reviewed demographic, clinical, and microbiologic data for all active TB cases reported in Montreal from 1996 to 2007 and identified persons who were homeless in the year prior to TB diagnosis. We genotyped all available Mycobacterium tuberculosis isolates by IS6110 restriction fragment length polymorphism (IS6110-RFLP) and spoligotyping, and used a geographic information system to identify potential locations for transmission between persons with matching isolates. Results There were 20 cases of TB in homeless persons, out of 1823 total reported from 1996-2007. 17/20 were Canadian-born, including 5 Aboriginals. Homeless persons were more likely than non-homeless persons to have pulmonary TB (20/20), smear-positive disease (17/20, odds ratio (OR) = 5.7, 95% confidence interval (CI): 1.7-20), HIV co-infection (12/20, OR = 14, 95%CI: 4.8-40), and a history of substance use. The median duration from symptom onset to diagnosis was 61 days for homeless persons vs. 28 days for non-homeless persons (P = 0.022). Eleven homeless persons with TB belonged to genotype-defined clusters (OR = 5.4, 95%CI: 2.2-13), and ten potential locations for transmission were identified, including health care facilities, homeless shelters/drop-in centres, and an Aboriginal community centre. Conclusions TB cases among homeless persons in Montreal raise concerns about delayed diagnosis and ongoing local transmission. PMID:22034944

In postherpetic neuralgia (PHN), dorsal root ganglia neurons are damaged. According to the proposed models, PHN pain might be associated with nociceptive deafferentation, and peripheral (heat hyperalgesia) or central sensitization (allodynia). In 36 PHN patients, afferent nerve fibre function was characterized using quantitative sensory testing and histamine-induced flare analysis. Psychological factors were evaluated with the Hospital Anxiety and Depression Scale (HADS), disease-related quality of life (QoL) with SF-36 and pain with the McGill questionnaire [pain rating index (PRI)]. The patients were also divided into subgroups according to the presence or absence of brush-evoked allodynia as a sign of central sensitization. For all patients, warm, cold and mechanical detection was impaired (p < 0.001 each) and the size of the histamine flare was diminished on the affected side (p < 0.05); pain thresholds with the exception of brush-evoked allodynia (p < 0.05) were unaltered. Correlation analysis revealed allodynia, anxiety, depression, QoL and age as relevant factors associated with pain severity (PRI). Allodynia was present in 23 patients (64%). In these patients, heat pain perception was preserved; the histamine flare was larger; the pinprick pain was increased as were McGill PRI sensory subscore, actual pain rating and almost significantly pain (McGill PRI) over the last 4 weeks. PHN is associated with damage of afferent fibres. Central sensitization (i.e., allodynia) might contribute to PHN pain. There was a striking association between anxiety, depression and age, and the magnitude of PHN pain. © 2014 European Pain Federation - EFIC®

Laminar Dust Flames: A Program of Microgravity and Ground Based Studies at McGill

Goroshin, Sam; Lee, John

1999-01-01

Fundamental knowledge of heterogeneous combustion mechanisms is required to improve utilization of solid fuels (e.g. coal), safe handling of combustible dusts in industry, and solid propulsion systems. The objective of the McGill University research program on dust combustion is to obtain a reliable set of data on basic combustion parameters for dust suspensions (i.e. laminar burning velocity, flame structure, quenching distance, flammability limits, etc.) over a range of particle sizes, dust concentrations, and types of fuel. This set of data then permits theoretical models to be validated and, when necessary, new models to be developed to describe the detailed reaction mechanisms and transport processes. Microgravity is essential to the generation of a uniform dust suspension of arbitrary particle size and concentration. When particles with a characteristic size on the order of tens of microns are suspended, they rapidly settle in a gravitational field. To maintain a particulate in suspension for time duration adequate to carry out combustion experiments invariably requires continuous convective flow in excess of the gravitational settling velocity (which is comparable with and can even exceed the dust laminar burning velocity). This makes the experiments turbulent in nature and thus renders it impossible to study laminar dust flames. Even for small particle sizes on the order of microns, a stable laminar dust flow can be maintained only for relatively low dust concentrations at normal gravity conditions. High dust loading leads to gravitational instability of the dust cloud and to the formation of recirculation cells in the dust suspension in a confined volume, or to the rapid sedimentation of the dense dust cloud, as a whole, in an unconfined volume. Many important solid fuels such as carbon and boron also have low laminar flame speeds (of the order of several centimeters per second). Convection that occurs in combustion products due to buoyancy disrupts the low speed dust flames and makes observation of such flames at normal gravity difficult.

Testing the reliability and efficiency of the pilot Mixed Methods Appraisal Tool (MMAT) for systematic mixed studies review.

Systematic literature reviews identify, select, appraise, and synthesize relevant literature on a particular topic. Typically, these reviews examine primary studies based on similar methods, e.g., experimental trials. In contrast, interest in a new form of review, known as mixed studies review (MSR), which includes qualitative, quantitative, and mixed methods studies, is growing. In MSRs, reviewers appraise studies that use different methods allowing them to obtain in-depth answers to complex research questions. However, appraising the quality of studies with different methods remains challenging. To facilitate systematic MSRs, a pilot Mixed Methods Appraisal Tool (MMAT) has been developed at McGill University (a checklist and a tutorial), which can be used to concurrently appraise the methodological quality of qualitative, quantitative, and mixed methods studies. The purpose of the present study is to test the reliability and efficiency of a pilot version of the MMAT. The Center for Participatory Research at McGill conducted a systematic MSR on the benefits of Participatory Research (PR). Thirty-two PR evaluation studies were appraised by two independent reviewers using the pilot MMAT. Among these, 11 (34%) involved nurses as researchers or research partners. Appraisal time was measured to assess efficiency. Inter-rater reliability was assessed by calculating a kappa statistic based on dichotomized responses for each criterion. An appraisal score was determined for each study, which allowed the calculation of an overall intra-class correlation. On average, it took 14 min to appraise a study (excluding the initial reading of articles). Agreement between reviewers was moderate to perfect with regards to MMAT criteria, and substantial with respect to the overall quality score of appraised studies. The MMAT is unique, thus the reliability of the pilot MMAT is promising, and encourages further development. Copyright © 2011 Elsevier Ltd. All rights reserved.

Astronomers Discover Fastest-Spinning Pulsar

NASA Astrophysics Data System (ADS)

2006-01-01

Astronomers using the National Science Foundation's Robert C. Byrd Green Bank Telescope have discovered the fastest-spinning neutron star ever found, a 20-mile-diameter superdense pulsar whirling faster than the blades of a kitchen blender. Their work yields important new information about the nature of one of the most exotic forms of matter known in the Universe. Pulsar Graphic Pulsars Are Spinning Neutron Stars CREDIT: Bill Saxton, NRAO/AUI/NSF (Click on image for larger version) "We believe that the matter in neutron stars is denser than an atomic nucleus, but it is unclear by how much. Our observations of such a rapidly rotating star set a hard upper limit on its size, and hence on how dense the star can be.," said Jason Hessels, a graduate student at McGill University in Montreal. Hessels and his colleagues presented their findings to the American Astronomical Society's meeting in Washington, DC. Pulsars are spinning neutron stars that sling "lighthouse beams" of radio waves or light around as they spin. A neutron star is what is left after a massive star explodes at the end of its "normal" life. With no nuclear fuel left to produce energy to offset the stellar remnant's weight, its material is compressed to extreme densities. The pressure squeezes together most of its protons and electrons to form neutrons; hence, the name "neutron star." "Neutron stars are incredible laboratories for learning about the physics of the fundamental particles of nature, and this pulsar has given us an important new limit," explained Scott Ransom, an astronomer at the National Radio Astronomy Observatory and one of Hessels' collaborators on this work. The scientists discovered the pulsar, named PSR J1748-2446ad, in a globular cluster of stars called Terzan 5, located some 28,000 light-years from Earth in the constellation Sagittarius. The newly-discovered pulsar is spinning 716 times per second, or at 716 Hertz (Hz), readily beating the previous record of 642 Hz from a pulsar discovered in 1982. For reference, the fastest speeds of common kitchen blenders are 250-500 Hz. The scientists say the object's fast rotation speed means that it cannot be any larger than about 20 miles across. According to Hessels, "If it were any larger, material from the surface would be flung into orbit around the star." The scientists' calculation assumed that the neutron star contains less than two times the mass of the Sun, an assumption that is consistent with the masses of all known neutron stars. The spinning pulsar has a companion star that orbits it once every 26 hours. The companion passes in front of the pulsar, eclipsing the pulsar about 40 percent of the time. The long eclipse period, probably due to bloating of the companion, makes it difficult for the astronomers to learn details of the orbital configuration that would allow them to precisely measure the masses of the pulsar and its companion. "If we could pin down these masses more precisely, we could then get a better limit on the size of the pulsar. That, in turn, would then give us a better figure for the true density inside the neutron star," explained Ingrid Stairs, an assistant professor at the University of British Columbia and another collaborator on the work. Competing theoretical models for the types and distributions of elementary particles inside neutron stars make widely different predictions about the pressure and density of such an object. "We want observational data that shows which models fit the reality of nature," Hessels said. If the scientists can't use PSR J1748-2446ad to do that, they are hopeful some of its near neighbors will yield the data they seek. Using the GBT, the astronomers so far have found 30 new fast "millisecond pulsars" in the cluster Terzan 5, making 33 pulsars known in the cluster in total. This is the largest number of such pulsars ever found in a single globular cluster. Dense globular clusters of stars are excellent places to find fast-rotating millisecond pulsars. Giant stars explode as supernovae and leave rotating pulsars which gradually slow down. However, if a pulsar has a companion star from which it can draw material, that incoming material imparts its spin, or angular momentum, to the pulsar. As a result, the pulsar spins faster. "In a dense cluster, interactions between the stars will create more binary pairs that can yield more fast-rotating pulsars," Ransom said. The great sensitivity of the giant, 100-meter diameter GBT, along with a special signal processor, called the Pulsar Spigot, made possible the discovery of so many millisecond pulsars in Terzan 5. "We think there are many more pulsars to be found in Terzan 5 and other clusters, and given that the fast ones are often hidden by eclipses, some of them may be spinning even faster than this new one," Ransom said. "We're excited about using this outstanding new telescope to answer some important questions about fundamental physics," he said. In addition to Hessels, Ransom and Stairs, the research team includes Paulo Freire of Arecibo Observatory in Puerto Rico, Victoria Kaspi, of McGill University, and Fernando Camilo, of Columbia University. Their report is being published in Science Express, the online version of the journal Science. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc. The pulsar research also was supported by the Canada Foundation for Innovation, the Natural Sciences and Engineering Research Council of Canada, the Quebec Foundation for Research on Nature and Technology, the Canadian Institute for Advanced Research, the Canada Research Chairs Program, and the National Science Foundation..

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.

Environmental effects of ozone depletion and its interactions with climate change: progress report, 2007.

PubMed

2008-01-01

This year the Montreal Protocol celebrates its 20th Anniversary. In September 1987, 24 countries signed the Montreal Protocol on Substances that Deplete the Ozone Layer. Today 191 countries have signed and have met strict commitments on phasing out of ozone depleting substances with the result that a 95% reduction of these substances has been achieved. The Montreal Protocol has also contributed to slowing the rate of global climate change, since most of the ozone depleting substances are also effective greenhouse gases. Even though much has been achieved, the future of the stratospheric ozone layer relies on full compliance of the Montreal Protocol by all countries for the remaining substances, including methyl bromide, as well as strict monitoring of potential risks from the production of substitute chemicals. Also the ozone depleting substances existing in banks and equipment need special attention to prevent their release to the stratosphere. Since many of the ozone depleting substances already in the atmosphere are long-lived, recovery cannot be immediate and present projections estimate a return to pre-1980 levels by 2050 to 2075. It has also been predicted that the interactions of the effects of the ozone layer and that of other climate change factors will become increasingly important.

Soucisse, Mikael L; Boulva, Kerianne; Sideris, Lucas; Drolet, Pierre; Morin, Michel; Dubé, Pierre

As surgical training is evolving and operative exposure is decreasing, new, effective, and experiential learning methods are needed to ensure surgical competency and patient safety. Video coaching is an emerging concept in surgery that needs further investigation. In this randomized controlled trial conducted at a single teaching hospital, participating residents were filmed performing a side-to-side intestinal anastomosis on cadaveric dog bowel for baseline assessment. The Surgical Video Coaching (SVC) group then participated in a one-on-one video playback coaching and debriefing session with a surgeon, during which constructive feedback was given. The control group went on with their normal clinical duties without coaching or debriefing. All participants were filmed making a second intestinal anastomosis. This was compared to their first anastomosis using a 7-category-validated technical skill global rating scale, the Objective Structured Assessment of Technical Skills. A single independent surgeon who did not participate in coaching or debriefing to the SVC group reviewed all videos. A satisfaction survey was then sent to the residents in the coaching group. Department of Surgery, HôpitalMaisonneuve-Rosemont, tertiary teaching hospital affiliated to the University of Montreal, Canada. General surgery residents from University of Montreal were recruited to take part in this trial. A total of 28 residents were randomized and completed the study. After intervention, the SVC group (n = 14) significantly increased their Objective Structured Assessment of Technical Skills score (mean of differences 3.36, [1.09-5.63], p = 0.007) when compared to the control group (n = 14) (mean of differences 0.29, p = 0.759). All residents agreed or strongly agreed that video coaching was a time-efficient teaching method. Video coaching is an effective and efficient teaching intervention to improve surgical residents' technical skills. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

Pathological gambling in Montreal's Chinese community: an anthropological perspective.

PubMed

Papineau, Elisabeth

2005-01-01

Pathological gambling has been identified as a major issue in Montreal's Chinese community. A variety of sources attest to the fact that, though we live in an increasingly heterogeneous society, the services provided to minority communities for preventing and treating pathological gambling are inadequate. An anthropological approach that takes into account cultural characteristics of one's community could lead to better strategies for acknowledgement, definition, diagnosis and treatment of pathological gambling among culturally different communities. Research paths that could help to provide effective treatment and services to specific populations are suggested. An overview of the way the Chinese view gambling, pathological gambling and treatment is presented. The concepts of fate, destiny and luck in Chinese thought, as well as Montreal's Chinese community social norms related to gambling are then described. The incorporation of those cultural understandings in future studies and treatment attempts is suggested.

Greek women and broken nerves in Montreal.

PubMed

Dunk, P

1989-05-01

In this paper, I examine the importance of class, ethnicity and gender in the causation and meaning of somatization for Greek women in Montreal. I argue that nevra--a form of psychosocial distress experienced by many of the women--is a phenomenon of the poor working conditions, low wages and gender relations in the Greek community. Data is based on interviews with 100 Greek families in Montreal and 45 patients in two different clinical settings. Comparing results with material on nervios and nerves from Latin America and the United States, I concur with Low (1985) that nerves should be viewed as a 'culturally-interpreted symptom' rather than a 'culture bound syndrome'. It is further suggested that the importance of social and material conditions and gender relations in mediating the cultural interpretation must be stressed. Failure to do so often results in the medicalization of nevra and the creation of a chronic sick role for the patient.

It is well established that anthropogenic chlorine-containing chemicals contribute to ozone layer depletion. The successful implementation of the Montreal Protocol has led to reductions in the atmospheric concentration of many ozone-depleting gases, such as chlorofluorocarbons. As a consequence, stratospheric chlorine levels are declining and ozone is projected to return to levels observed pre-1980 later this century. However, recent observations show the atmospheric concentration of dichloromethane-an ozone-depleting gas not controlled by the Montreal Protocol-is increasing rapidly. Using atmospheric model simulations, we show that although currently modest, the impact of dichloromethane on ozone has increased markedly in recent years and if these increases continue into the future, the return of Antarctic ozone to pre-1980 levels could be substantially delayed. Sustained growth in dichloromethane would therefore offset some of the gains achieved by the Montreal Protocol, further delaying recovery of Earth's ozone layer.

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.

The present study aimed to develop a Japanese version of the Short-Form McGill Pain Questionnaire (SF-MPQ-J) that focuses on cross-culturally equivalence to the original English version and to test its reliability and validity. Cross-sectional design. In study 1, SF-MPQ was translated and adapted into Japanese. It included construction of response scales equivalent to the original using a variation of the Thurstone method of equal-appearing intervals. A total of 147 undergraduate students and 44 pain patients participated in the development of the Japanese response scales. To measure the equivalence of pain descriptors, 62 pain patients in four diagnostic groups were asked to choose pain descriptors that described their pain. In study 2, chronic pain patients (N=126) completed the SF-MPQ-J, the Long-Form McGill Pain Questionnaire Japanese version (LF-MPQ-J), and the 11-point numerical rating scale of pain intensity. Correlation analysis examined the construct validity of the SF-MPQ-J. The results from study 1 were used to develop SF-MPQ-J, which is linguistically equivalent to the original questionnaire. Response scales from SF-MPQ-J represented the original scale values. All pain descriptors, except one, were used by >33% in at least one of the four diagnostic groups. Study 2 exhibited adequate internal consistency and test-retest reliability, with the construct validity of SF-MPQ-J comparable to the original. These findings suggested that SF-MPQ-J is reliable, valid, and cross-culturally equivalent to the original questionnaire. Researchers might consider using this scale in multicenter, multi-ethnical trials or cross-cultural studies that include Japanese-speaking patients. Wiley Periodicals, Inc.

This study aimed to investigate the effect of dry cupping therapy and acupressure at BL23 point on the intensity of postpartum perineal pain based on the short-form of McGill pain questionnaire (SMPQ). The present clinical trial was conducted on 150 subjects in 3 groups of 50 cases. After at least 4-8 hr of delivery, cupping therapy was performed for 15-20 min up to 3 times a week (once a day) and acupressure was performed for 15-20 min based on clockwise model. The short-form of McGill pain questionnaire was completed both before and after the intervention. The SPSS statistical software was used to analyze the data using repeated measures ANOVA. Besides, p<0.05 was considered statistically significant. In the cupping therapy group, mean of the perineal pain intensity reduced from 37.5±6.8 before the intervention to 11.1±6.1, 6.9±4.7, and 3.8±3.6 immediately, 24 hr, and 2 weeks after the intervention, respectively. The results of study showed that the differences between the intervention and control groups were statistically significant (p<0.01). Mean difference of the perineal pain intensity in the acupressure group reached from 35.6±8.1 before the intervention to 10.4±5.5 two weeks after the intervention, so the variation between intervention and control groups was statistically significant. The study findings showed that cupping therapy and acupressure reduced perineal pain. Therefore, they may be considered as effective treatments for reducing pain intensity of allowing delivery.

To examine whether Modic changes influence pain during a 1-year follow-up in patients with lumbar radicular pain. A total of 243 patients with lumbar radicular pain due to disc herniation were recruited from two hospitals in Norway and followed up at 6 weeks, 6 months, and 12 months. On baseline lumbar magnetic resonance images, two observers independently evaluated Modic changes (types I-III; craniocaudal size 0-3). Outcomes were sensory pain (McGill Pain Questionnaire), back and leg pain (visual analogue scale, VAS). Association between Modic type and outcomes was explored with a mixed model and then by two-way analysis of variance (ANOVA) at each time point with Modic and treatment groups (surgical, n = 126; nonsurgical, n = 117) as fixed factors, adjusted for disc degeneration, age, sex, smoking, and duration of radicular pain. Modic size was also analyzed using ANOVA. Pain scores had decreased significantly at 1-year follow-up. Modic type was significantly related to McGill sensory scores (mixed model: p = 0.014-0.026; ANOVA: p = 0.007 at 6 weeks), but not to VAS back pain or VAS leg pain scores. At 6 weeks, the mean McGill sensory score was higher in Modic I than in Modic II-III patients (p = 0.003) and in patients without Modic changes (p = 0.018). Modic size L1-S1 was not associated with pain outcomes. Patients with lumbar radicular pain have a substantial pain reduction during 1-year follow-up, but Modic type I changes may imply a slower initial decrease in sensory pain.

Seeking Connectivity in Nurses' Work Environments: Advancing Nurse Empowerment Theory.

PubMed

Udod, Sonia

2014-09-01

The purpose of this study was to investigate how staff nurses and their managers exercise power in a hospital setting in order to better understand what fosters or constrains staff nurses' empowerment and to extend nurse empowerment theory. Power is integral to empowerment, and attention to the challenges in nurses' work environment and nurse outcomes by administrators, researchers, and policy-makers has created an imperative to advance a theoretical understanding of power in the nurse-manager relationship. A sample of 26 staff nurses on 3 units of a tertiary hospital in western Canada were observed and interviewed about how the manager affected their ability to do their work. Grounded theory methodology was used. The process of seeking connectivity was the basic social process, indicating that the manager plays a critical role in the work environment and nurses need the manager to share power with them in the provision of safe, quality patient care.

2014-09-01

Males represent approximately 6.8% of registered nurses in Canada and consequently constitute an untapped health workforce resource. The authors investigated environmental work factors in the acute-care setting and their influence on male RNs' job satisfaction and intention to stay in the profession. They conducted a cross-sectional study of male RNs employed in acute-care settings in the province of Ontario. Correlations and multiple regression analyses were used to examine career satisfaction and intentions. Nurses who were most satisfied with their career valued extrinsic rewards (pay, vacation, and benefits), control and responsibility, and opportunities for professional development; those who were least satisfied and voiced their intention to leave the profession tended to work part time, experience gender mistreatment, and be dissatisfied with extrinsic awards, scheduling, and organizational support. A unique finding of this study relates to the significant predictive relationship between gender mistreatment and males' intention to leave.

Rethinking Case Study Methodology in Poststructural Research.

PubMed

Mohammed, Shan; Peter, Elizabeth; Gastaldo, Denise; Howell, Doris

2015-03-01

Little consideration has been given to how case study might be used in poststructural research to explore power relations that constitute a phenomenon. Many case study scholars, most notably Robert Yin, adopt a postpositivist perspective that assumes the "truth" can be accessed through applying prescriptive and rigid research techniques. Using a discussion of Michel Foucault's key theoretical ideas and the insights gained through a Foucauldian case study of people with advanced cancer who continue to receive curative treatment, the authors argue for the expansion of case study in poststructural inquiry. They propose that the use of poststructuralist case study is valuable because of the flexibility and comprehensiveness of the methodology, which allows for the exploration of a deeper understanding of the broader discourses that shape a phenomenon, as well as how power/knowledge relations shape the behaviours and perceptions of people. They also introduce the reflexive implications of poststructural case study research. Copyright© by Ingram School of Nursing, McGill University.

The objective of this study was to ascertain the information needs and knowledge-dissemination preferences of acute-care administrators with respect to advanced practice nursing (APN). Supportive leadership is imperative for the success of APN roles and administrators need up-to-date research evidence and information, but it is unclear what the information needs of administrators are and how they prefer to receive the information. A survey tool was developed from the literature and from the findings of a qualitative study with acute-care leaders. Of 107 surveys distributed to nursing administrators in 2 teaching hospitals, 79 (73.8%) were returned. Just over half of respondents reported wanting APN information related to model of care and patient and systems outcomes of APN care; the majority expressed a preference for electronic transmission of the information. Researchers need multiple strategies for distributing context-specific APN evidence and information to nursing administrators. Copyright© by Ingram School of Nursing, McGill University.

Knowledge about the beneficial effects of social support has not been used to systematically develop and evaluate interventions to help refugee new parents cope. The purpose of this study was to design and evaluate a social support intervention for refugee new parents. A multi-method research design was used and participatory research strategies were employed. Qualitative and quantitative measures were used to understand experiences of participants and to assess the perceived psychosocial and health-related outcomes of the intervention. Mentored support groups, matched by gender and ethnicity, met biweekly over 7 months. The participants were 48 Sudanese and 37 Zimbabwean refugee parents in 2 Canadian provinces. Increases were found in informational support, spousal support, community engagement, coping, and support-seeking. Decreases were found in parenting stress, loneliness, and isolation. The authors conclude that there is a need for culturally appropriate nursing practices and programs for refugee new parents from diverse cultures.

Reality Check: Are We Truly Preparing Our Students for Interprofessional Collaborative Practice?

Salfi, Jenn; Mohaupt, Jennifer; Patterson, Christine; Allen, Dianne

2015-06-01

Many academic settings offer interprofessional education (IPE) experiences that are of short duration and situated in safe, controlled environments such as classrooms or simulation labs. The purpose of this study was to examine the effects of a 10-week IPE strategy that was incorporated into the final clinical practicum of a BScN program. A mixed methods design was chosen, in the belief that qualitative data would help explain quantitative data from pre-test/post-test design (n = 268). Quantitative results revealed that participants disagreed more with statements on interprofessional collaboration (IPC) after completion of the strategy (p = 0.00). Qualitative findings reinforced these results, revealing a theme of common sense is not so common when it comes to IPC in the health-care setting. When student nurses are being prepared for IPC, IPE strategies should be as "real" as possible, with exposure to some of the realities of interprofessional team functioning.

Rural patients can wait up to 32 hours for transfer to cardiac catheterization (CATH) for events related to acute coronary syndrome (ACS). Pain arising from myocardial ischemia can be severe and anxiety-provoking. Pain management during this time should be optimized in order to preserve vulnerable myocardial muscle. This qualitative focus group study solicited the perspectives of ACS patients and emergency staff nurses on the rural patient experience of cardiac pain and anxiety and priorities and barriers to optimal assessment and management of ACS pain. Patients described ACS pain as moderate to severe, with pain in the chest, arms, back, shoulders, and jaw. Pain was well assessed and managed upon arrival in the emergency department but anxiety was not routinely assessed or treated. Barriers identified were poor management of patients with different acuity levels, high patient volumes, and assumptions regarding patients' communication about pain. Research related to ACS pain and anxiety management in the rural context is recommended. Copyright© by Ingram School of Nursing, McGill University.

The purpose of this study was to design an approach to supporting the development of gender- and Aboriginal-specific messages regarding the link between tobacco exposure and breast cancer, drawing on youth perspectives. Focus groups were held with 18 girls (8 First Nations and Métis) and 25 boys (12 First Nations and Métis) to solicit advice in the design of messages. Transcribed data were analyzed for themes. Girls preferred messages that included the use of novel images, a personal story of breast cancer, and ways to avoid secondhand smoke. Boys endorsed messages that were "catchy" but not "cheesy" and had masculine themes. First Nations and Métis participants confirmed the use of Aboriginal symbols in messages as signalling their relevance to youth in their communities. The results can be used as a guide in developing tailored health promotion messages. Challenges in developing gender-appropriate messages for youth are described.

2015-03-01

Mi'kmaq women are reported to have lower rates of Papanicolaou (Pap) screening and higher rates of cervical cancer than non-Aboriginal women. This qualitative participatory study used postcolonial feminist perspectives and Indigenous principles to explore Mi'kmaq women's experiences with Pap screening within the contexts that shaped their experiences. Community facilitators assisted with the research process. Talking circles and individual in-depth interviews were conducted with 16 Mi'kmaq women. Also, health-care providers were interviewed in 2 Mi'kmaq communities. The findings indicate that historical and social contexts are shaping Mi'kmaq women's screening experiences and that these experiences are diverse, as are their understandings about screening. Some women were accessing regular screening despite challenging personal circumstances. The results highlight the need for nurses and other health-care providers to understand the uniqueness of each woman's experiences with Pap screening. Improvements in screening rates depend on multifaceted nursing approaches developed in partnership with Mi'kmaq women. Copyright© by Ingram School of Nursing, McGill University.

Estimate the number of awakenings additional to spontaneous awakenings, induced by the nighttime aircraft movements at an international airport in Montreal, in the population residing nearby in 2009. Maximum sound levels (LAS,max) were derived from aircraft movements using the Integrated Noise Model 7.0b, on a 28 x 28 km grid centred on the airport and with a 0.1 x 0.1 km resolution. Outdoor LAS,max were converted to indoor LAS,max by reducing noise levels by 15 dB(A) or 21 dB(A). For all grid points, LAS,max were transformed into probabilities of additional awakening using a function developed by Basner et al. (2006). The probabilities of additional awakening were linked to estimated numbers of exposed residents for each grid location to assess the number of aircraft-noise-induced awakenings in Montreal. Using a 15 dB(A) sound attenuation, 590 persons would, on average, have one or more additional awakenings per night for the year 2009. In the scenario using a 21 dB(A) sound attenuation, on average, no one would be subjected to one or more additional awakenings per night due to aircraft noise. Using the 2009 flight patterns, our data suggest that a small number of Montreal residents are exposed to noise levels that could induce one or more awakenings additional to spontaneous awakenings per night.

The current version of the androgen receptor (AR) gene mutations database is described. The total number of reported mutations has risen from 309 to 374 during the past year. We have expanded the database by adding information on AR-interacting proteins; and we have improved the database by identifying those mutation entries that have been updated. Mutations of unknown significance have now been reported in both the 5' and 3' untranslated regions of the AR gene, and in individuals who are somatic mosaics constitutionally. In addition, single nucleotide polymorphisms, including silent mutations, have been discovered in normal individuals and in individuals with male infertility. A mutation hotspot associated with prostatic cancer has been identified in exon 5. The database is available on the internet (http://www.mcgill.ca/androgendb/), from EMBL-European Bioinformatics Institute (ftp.ebi.ac.uk/pub/databases/androgen), or as a Macintosh FilemakerPro or Word file (MC33@musica.mcgill.ca).

2016-12-01

This randomized controlled study assessed the efficacy of active music therapy (AMT) on anxiety, depression, and quality of life in amyotrophic lateral sclerosis (ALS). Communication and relationship during AMT treatment were also evaluated. Thirty patients were assigned randomly to experimental [AMT plus standard of care (SC)] or control (SC) groups. AMT consisted of 12 sessions (three times a week), whereas the SC treatment was based on physical and speech rehabilitation sessions, occupational therapy, and psychological support. ALS Functional Rating Scale-Revised, Hospital Anxiety and Depression Scale, McGill Quality of Life Questionnaire, and Music Therapy Rating Scale were administered to assess functional, psychological, and music therapy outcomes. The AMT group improved significantly in McGill Quality of Life Questionnaire global scores (P=0.035) and showed a positive trend in nonverbal and sonorous-music relationship during the treatment. Further studies involving larger samples in a longer AMT intervention are needed to confirm the effectiveness of this approach in ALS.

The authors of this article argue that classroom education does not fit the museum setting and that researchers need to re-think the basic principles for the use of museums in adult education. In order to do this, it is necessary to understand the psychology of the museum visitor. However, while much has been published on visitor behaviour and the factors influencing it, very little is known about what visitors think or feel in the exhibition room. A research team at the University of Montreal is currently studying the psychological reactions of adults when observing museum exhibits. This paper describes the methodology used by this team, some of the results obtained and the perspectives opened up by the study.

Wearable Device-Based Gait Recognition Using Angle Embedded Gait Dynamic Images and a Convolutional Neural Network.

2017-02-28

The widespread installation of inertial sensors in smartphones and other wearable devices provides a valuable opportunity to identify people by analyzing their gait patterns, for either cooperative or non-cooperative circumstances. However, it is still a challenging task to reliably extract discriminative features for gait recognition with noisy and complex data sequences collected from casually worn wearable devices like smartphones. To cope with this problem, we propose a novel image-based gait recognition approach using the Convolutional Neural Network (CNN) without the need to manually extract discriminative features. The CNN's input image, which is encoded straightforwardly from the inertial sensor data sequences, is called Angle Embedded Gait Dynamic Image (AE-GDI). AE-GDI is a new two-dimensional representation of gait dynamics, which is invariant to rotation and translation. The performance of the proposed approach in gait authentication and gait labeling is evaluated using two datasets: (1) the McGill University dataset, which is collected under realistic conditions; and (2) the Osaka University dataset with the largest number of subjects. Experimental results show that the proposed approach achieves competitive recognition accuracy over existing approaches and provides an effective parametric solution for identification among a large number of subjects by gait patterns.

The association between diagnosed acute ST-elevation myocardial infarction (STEMI) and hockey games in the Canadian population is unknown. We retrospectively analyzed the association between hockey games of the National Hockey League Montreal Canadiens and daily hospital admissions for acute STEMI at the Montreal Heart Institute, Canada. Between June 2010 and December 2014, a total of 2199 patients (25.9% women; mean age, 62.6 ± 12.4 years) were admitted for acute STEMI. An increase in STEMI admissions was observed the day after a hockey game of the Montreal Canadiens in the overall population (from 1.3 ± 1.2 to 1.5 ± 1.3), however, this difference was not significant (P = 0.1). The number of STEMI admissions increased significantly from 0.9 ± 1.0 to 1.2 ± 1.0 per day in men (P = 0.04), but not in women (P = 0.7). The association between ice hockey matches and STEMI admission rates was strongest after a victory of the Montreal Canadiens. Accordingly, an increased risk for the occurrence of STEMI was observed in the overall population (hazard ratio [HR], 1.15; 95% confidence interval [CI], 1.0-1.3; P = 0.037) when the Montreal Canadiens won a match. This association was present in men (HR, 1.2; 95% CI, 1.03-1.4; P = 0.02) but not in women (P = 0.87), with a most pronounced effect seen in younger men (younger than 55 years; HR, 1.4; 95% CI, 1.1-1.8; P = 0.009). Although a weak association between hockey games and hospital admissions for STEMI was found in our overall population, the event of a hockey game significantly increased the risk for STEMI in younger men. Preventive measures targeting behavioural changes could positively affect this risk. Copyright © 2018 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

Community unemployment and immigrants' health in Montreal.

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. Findings among first-generation immigrants are interpreted with respect to the effects of possible discrimination in areas with low job availability. Among second-generation men, poor physical health and obesity may be the result of poor health habits stemming from perceived lack of life opportunities.

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">

A Difference-in-Differences Approach to Assess the Effect of a Heat Action Plan on Heat-Related Mortality, and Differences in Effectiveness According to Sex, Age, and Socioeconomic Status (Montreal, Quebec).

The impact of heat waves on mortality and health inequalities is well documented. Very few studies have assessed the effectiveness of heat action plans (HAPs) on health, and none has used quasi-experimental methods to estimate causal effects of such programs. We developed a quasi-experimental method to estimate the causal effects associated with HAPs that allows the identification of heterogeneity across subpopulations, and to apply this method specifically to the case of the Montreal (Quebec, Canada) HAP. A difference-in-differences approach was undertaken using Montreal death registry data for the summers of 2000-2007 to assess the effectiveness of the Montreal HAP, implemented in 2004, on mortality. To study equity in the effect of HAP implementation, we assessed whether the program effects were heterogeneous across sex (male vs. female), age (≥ 65 years vs. < 65 years), and neighborhood education levels (first vs. third tertile). We conducted sensitivity analyses to assess the validity of the estimated causal effect of the HAP program. We found evidence that the HAP contributed to reducing mortality on hot days, and that the mortality reduction attributable to the program was greater for elderly people and people living in low-education neighborhoods. These findings show promise for programs aimed at reducing the impact of extreme temperatures and health inequities. We propose a new quasi-experimental approach that can be easily applied to evaluate the impact of any program or intervention triggered when daily thresholds are reached.

Although there is some debate about whether the depressions formed by means of sublimation or evaporation, it is commonly believed that the terrain in which the depressions occur is ice-rich.Moreover, most workers assume that this "ice-richness" is derived of a bi-hemispheric, latitudinally-dependent and atmospherically-precipitated mantle that is metres thick [2,4,6-10].

To examine the mechanisms of injury for concussions in university football, ice hockey, and soccer. Prospective cohort design. McGill University Sport Medicine Clinic. Male and female athletes participating in varsity football, ice hockey, and soccer. Athletes were followed prospectively over a 10-year period to determine the mechanisms of injury for concussions and whether contact with certain areas of the body or individual variables predisposed to longer recovery from concussions. For soccer, data were collected on whether concussions occurred while attempting to head the ball. There were 226 concussions in 170 athletes over the study period. The side/temporal area of the head or helmet was the most common area to be struck resulting in concussion in all 3 sports. Contact from another player's head or helmet was the most probable mechanism in football and soccer. In hockey, concussion impacts were more likely to occur from contact with another body part or object rather than another head/helmet. Differences in mechanisms of injuries were found between males and females in soccer and ice hockey. Athletes with multiple concussions took longer to return to play with each subsequent concussion. Half of the concussions in soccer were related to attempting to head the soccer ball. The side of the head or helmet was the most common area to be struck resulting in concussion in all 3 sports. In ice hockey and soccer, there are differences in the mechanisms of injury for males and females within the same sport.

The authors, both family physicians, report on a profile of fifty-eight (58) Montreal narcotic addicts admitted to a methadone treatment program in 1986. Their characteristic are similar to those published for addicts being treated in the United States. In particular, there is a high rate of involvement with crime, multiple drug abuse and family histories of violence. Certain characteristics are very helpful in the planning of future resources for the Montreal area and suggest possible avenues to primary prevention. The question is asked about which factors, if any, have prognostic significance. PMID:21248864

Dermatological disorders accounted for 18.8% and 15.2%, respectively, of all the dogs and cats examined at the Small Animal Clinic, University of Montreal, Saint-Hyacinthe, during a one-year period. In dogs, the most common groups of dermatological disorders encountered were bacterial folliculitis and furunculosis, allergic dermatitis, endocrinopathy, neoplasia, ectoparasitism, and immune-mediated dermatitis. The most common primary final diagnoses were bacterial folliculitis and furunculosis, atopy, food hypersensitivity, flea bite hypersensitivity, hyperadrenocorticism, and hypothyroidism. Breed predispositions were found for several canine dermatoses: bacterial folliculitis and furunculosis (collie, German shepherd, golden retriever, Newfoundland), atopy (boxer, golden retriever), food hypersensitivity (boxer, German shepherd), hyperadrenocorticism (miniature poodle), hypothyroidism (Doberman pinscher, Gordon setter), castration-responsive alopecia (chow chow), demodicosis (Old English sheepdog), and idiopathic pruritus (pit bull terrier). In cats, the most common dermatoses were abscesses, otodectic mange, cheyletiellosis, flea bite hypersensitivity, atopy, flea infestation, neoplasia, and food hypersensitivity. Himalayan and Persian cats accounted for 50% of the cases of cheyletiellosis and 75% of the cases of dermatophytosis, respectively. Hereditary primary seborrhea oleosa was seen only in Persian cats.

Derwent, R. G.; Simmonds, P. G.; Greally, B. R.; O'doherty, S.; McCulloch, A.; Manning, A.; Reimann, S.; Folini, D.; Vollmer, M. K.

The mixing ratios of HCFC-141b (1,1-dichlorofluoroethane) and HCFC-142b (1-chloro-1,1-difluoroethane) have been rising steadily in baseline air at Mace Head, Ireland over the 10-year period from 1994 to 2004. These HCFCs are widely used replacements for the chlorofluorocarbons phased out under the Montreal Protocol and its subsequent amendments. Analysis of the HCFC content of regionally-polluted air arriving at Mace Head from the European continent shows that European emissions reached a peak during 2000-2001 and have declined subsequently, following the phase-out in their usage. European emissions of HCFC-141b have been further constrained by observations at the High-Alpine Jungfraujoch site. The reductions are consistent with the phase-out of HCFC production and use from the year 2001 onwards mandated by European regulations designed to exceed the requirements of the Montreal Protocol.

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

Few studies have examined potential disparities in access to transportation infrastructures, an important determinant of population health. To examine individual- and area-level disparities in access to the road network, public transportation system, and a public bicycle share program in Montreal, Canada. Examining associations between sociodemographic variables and access to the road network, public transportation system, and a public bicycle share program, 6,495 adult respondents (mean age, 48.7 years; 59.0 % female) nested in 33 areas were included in a multilevel analysis. Individuals with lower incomes lived significantly closer to public transportation and the bicycle share program. At the area level, the interaction between low-education and low-income neighborhoods showed that these areas were significantly closer to public transportation and the bicycle share program controlling for individual and urbanicity variables. More deprived areas of the Island of Montreal have better access to transportation infrastructure than less-deprived areas.

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

PubMed

DeCanio, Stephen J; Norman, Catherine S

2007-10-01

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.

OBJECTIVE: To assess the clinical performance of a representative non-volunteer sample of family physicians in metropolitan Montreal, Que. DESIGN: Assessment of clinical performance was based on inspection visits to offices, peer review of medical records, and chart-stimulated recall interviews. The procedure was the one usually followed by the Professional Inspection Committee of the Collège des médecins du Québec. SETTING: Family physicians' practices in metropolitan Montreal. PARTICIPANTS: One hundred randomly selected family physicians. INTERVENTIONS: For each physician, 30 randomly chosen patient charts with data on three to five previous visits were reviewed using explicit criteria and a standard scale using global scores from 1 to 5 (unacceptable to excellent). MAIN OUTCOME MEASURES: Scores were assigned for office practices; record keeping; number of continuing medical education (CME) activities; and quality of clinical performance assessed in terms of investigation plan, diagnostic accuracy, treatment plan, and relevance of care. RESULTS: Overall performance was judged to be good to excellent for 98% of physicians in their private practices; for 90% of physicians concerning CME activities; for 94% of physicians concerning their clinical performance in terms of quality of care; and for 75% of physicians as to record keeping. There was a link between record keeping and quality of care as well as between the number of CME activities and quality of care. CONCLUSION: The overall clinical performance of family physicians in the greater Montreal region is excellent. PMID:12228963

2015-04-01

Due to a complex set of feedback processes collectively known as "polar amplification", the Arctic realm is expected to experience a greater-than-average response to global climate forcing. The cascades of feedback processes that connect the Arctic cryosphere, ocean and atmosphere remain incompletely constrained by observations and theory and are difficult to simulate in climate models. Our capacity to predict the future of the region and assess the impacts of Arctic change processes on global and regional environments hinges on the availability of interdisciplinary experts with strong international experience and understanding of the science/society interface. This is the basis of the International Research Training Group "Processes and impacts of climate change in the North Atlantic Ocean and the Canadian Arctic - ArcTrain", which was initiated in 2013. ArcTrain aims to educate PhD students in an interdisciplinary environment that combines paleoclimatology, physical oceanography, remote sensing and glaciology with comprehensive Earth system modelling, including sea-ice and ice-sheet components. The qualification program for the PhD students includes joint supervision, mandatory research residences at partner institutions, field courses on land and on sea (Floating University), annual meetings and training workshops and a challenging structured training in expert skills and transferrable skills. Its aim is to enhance the career prospects and employability of the graduates in a challenging international job market across academic and applied sectors. ArcTrain is a collaborative project at the University of Bremen and the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven. The German part of the project is designed to continue for nine years and educate three cohorts of twelve PhD students each. The Canadian partners comprise a consortium of eight universities led by the GEOTOP cluster at the Université du Québec à Montréal and including Dalhousie University, McGill University, Memorial University of Newfoundland, University of Alberta, University of British Columbia, University of Calgary and Université du Québec à Rimouski.

Lock, Margaret; Wakewich-Dunk, Pamela

1990-01-01

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

Given the heterogeneous nature of Crohn's disease (CD), our aim was to apply the Montreal Classification to a large cohort of Portuguese patients with CD in order to identify potential predictive regarding the need for medical and/or surgical treatment. A cross-sectional study was used based on data from an on-line registry of patients with CD. Of the 1692 patients with 5 or more years of disease, 747 (44%) were male and 945 (56%) female. On multivariate analysis the A2 group was an independent risk factor of the need for steroids (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.1-2.3) and the A1 and A2 groups for immunosuppressants (OR 2.2; CI 1.2-3.8; OR 1.4; CI 1.0-2.0, respectively). An L3+L3(4) and L(4) location were risk factors for immunosuppression (OR 1.9; CI 1.5-2.4), whereas an L1 location was significantly associated with the need for abdominal surgery (P < 0.001). After 20 years of disease, less than 10% of patients persisted without steroids, immunosuppression, or surgery. The Montreal Classification allowed us to identify different groups of disease severity: A1 were more immunosuppressed without surgery, most of A2 patients were submitted to surgery, and 52% of L1+L1(4) patients were operated without immunosuppressants. Stratifying patients according to the Montreal Classification may prove useful in identifying different phenotypes with different therapies and severity. Most of our patients have severe disease.

Objectives: We propose a novel approach to examine vulnerability in the relationship between heat and years of life lost and apply to neighborhood social disparities in Montreal and Paris. Methods: We used historical data from the summers of 1990 through 2007 for Montreal and from 2004 through 2009 for Paris to estimate daily years of life lost social disparities (DYLLD), summarizing social inequalities across groups. We used Generalized Linear Models to separately estimate relative risks (RR) for DYLLD in association with daily mean temperatures in both cities. We used 30 climate scenarios of daily mean temperature to estimate future temperature distributions (2021–2050). We performed random effect meta-analyses to assess the impact of climate change by climate scenario for each city and compared the impact of climate change for the two cities using a meta-regression analysis. Results: We show that an increase in ambient temperature leads to an increase in social disparities in daily years of life lost. The impact of climate change on DYLLD attributable to temperature was of 2.06 (95% CI: 1.90, 2.25) in Montreal and 1.77 (95% CI: 1.61, 1.94) in Paris. The city explained a difference of 0.31 (95% CI: 0.14, 0.49) on the impact of climate change. Conclusion: We propose a new analytical approach for estimating vulnerability in the relationship between heat and health. Our results suggest that in Paris and Montreal, health disparities related to heat impacts exist today and will increase in the future. PMID:26402690

Montreal Cognitive Assessment (MoCA) is a new cognitive tool developed for screening mild cognitive impairment (MCI). The authors examined validity of MoCA and discriminating power of subtests in a Turkish population comprising of 474 participants (246 healthy controls, 114 subjects with MCI and 114 subjects with dementia). The ANCOVAs showed that age and education had a main effect on MoCA scores. Cut scores were computed according to different education levels. The overall cut-off values for MCI and dementia were found to be lower compared to western studies. MoCA was found to have good internal consistency. The subtests most useful in discriminating MCI from healthy controls were recall, visuospatial and language, while in discriminating dementia from MCI were visuospatial, orientation and attention subtests. The results demonstrated that MoCA is a valid and reliable instrument in screening MCI, and compared with the MMSE, MoCA was proved to have superior sensitivity and specificity in detecting MCI. © The Author(s) 2014.

Global warming potential estimates for the C1-C3 hydrochlorofluorocarbons (HCFCs) included in the Kigali Amendment to the Montreal Protocol

Hydrochlorofluorocarbons (HCFCs) are ozone depleting substances and potent greenhouse gases that are controlled under the Montreal Protocol. However, the majority of the 274 HCFCs included in Annex C of the protocol do not have reported global warming potentials (GWPs) which are used to guide the phaseout of HCFCs and the future phase down of hydrofluorocarbons (HFCs). In this study, GWPs for all C1-C3 HCFCs included in Annex C are reported based on estimated atmospheric lifetimes and theoretical methods used to calculate infrared absorption spectra. Atmospheric lifetimes were estimated from a structure activity relationship (SAR) for OH radical reactivity and estimated O(1D) reactivity and UV photolysis loss processes. The C1-C3 HCFCs display a wide range of lifetimes (0.3 to 62 years) and GWPs (5 to 5330, 100-year time horizon) dependent on their molecular structure and the H-atom content of the individual HCFC. The results from this study provide estimated policy-relevant GWP metrics for the HCFCs included in the Montreal Protocol in the absence of experimentally derived metrics.

Background: Perineal pain is a major morbidity in the first few days after delivery. This study aimed to investigate the effect of dry cupping therapy and acupressure at BL23 point on the intensity of postpartum perineal pain based on the short-form of McGill pain questionnaire (SMPQ). Methods: The present clinical trial was conducted on 150 subjects in 3 groups of 50 cases. After at least 4–8 hr of delivery, cupping therapy was performed for 15–20 min up to 3 times a week (once a day) and acupressure was performed for 15–20 min based on clockwise model. The short-form of McGill pain questionnaire was completed both before and after the intervention. The SPSS statistical software was used to analyze the data using repeated measures ANOVA. Besides, p<0.05 was considered statistically significant. Results: In the cupping therapy group, mean of the perineal pain intensity reduced from 37.5±6.8 before the intervention to 11.1±6.1, 6.9±4.7, and 3.8±3.6 immediately, 24 hr, and 2 weeks after the intervention, respectively. The results of study showed that the differences between the intervention and control groups were statistically significant (p<0.01). Mean difference of the perineal pain intensity in the acupressure group reached from 35.6±8.1 before the intervention to 10.4±5.5 two weeks after the intervention, so the variation between intervention and control groups was statistically significant. Conclusion: The study findings showed that cupping therapy and acupressure reduced perineal pain. Therefore, they may be considered as effective treatments for reducing pain intensity of allowing delivery. PMID:26962482

Wilder Penfield and the Montreal Neurological Institute (MNI) are inextricably linked. It was Penfield's unique idea to create a building with an academic atmosphere wherein basic neuroscience and clinical care of neurological patients would benefit from interaction and mutual support. It is clear that without Penfield that there would be no MNI; however, the role of another Canadian icon, Sir Arthur Currie, in the development of the MNI has heretofore been barely mentioned. The thesis of this paper is that Currie had a critical role in the gestation of the MNI that has generally been ignored.

Loranger, Camille; Moreau, Linda; Sasseville, Denis

Aircraft building exposes workers to irritant and sensitizing products. The aim of this article was to study occupational dermatoses among aircraft workers over 25 years. The files of aerospace workers referred between 1990 and 2015 were extracted from the database of the McGill University Health Centre contact dermatitis clinic. These were subdivided according to demographics, type of work, patch testing results, and final diagnosis. Of 305 workers, 58% were 40 years or younger; one third were women. Onset of dermatitis varied from 2 months to 25 years, but 120 cases (39%) occurred during the first 3 years. Fifty-one percent of the cases involved assemblers, and 27% were composite material technicians, which were overrepresented as they constitute 10% of the workforce. Of the 305 workers, 152 suffered from allergic contact dermatitis, and 96 had irritant contact dermatitis. Of those with allergic contact dermatitis, 124 reacted to epoxy-based workplace products, but only 48 had positive patch tests to commercially available epoxy allergens. More than 60% of the cases of epoxy allergy would have been missed without testing with workplace products.

Withdrawal of participants from intervention studies has dire methodological and clinical consequences. Attrition rates in smoking cessation studies have been found to be particularly high. Identifying factors that contribute to attrition may inform strategies to address the problem and prevent its consequences. This systematic review had 2 objectives: to report attrition rates, and to identify factors that influence attrition of adult smokers participating in smoking cessation intervention studies. Inclusion criteria were (1) published between 1980 and 2015; (2) experimental or quasi-experimental design; (3) pharmacological, educational, or behavioural intervention; (4) target population of adult smokers; (5) examination of attrition rate; and (6) exploration of factors associated with attrition and/or of reasons given by participants for withdrawing. These criteria were met by 10 studies. Attrition rates ranged from 10.8% to 77%. A small number of demographic, clinical, behavioural, health, health-related beliefs, and logistical factors were related to attrition. The report of high attrition rates underlines the importance of incorporating strategies to minimize attrition in smoking cessation studies. Strategies to reduce attrition are proposed.

Phosphorus cycling in Montreal's food and urban agriculture systems.

Metson, Geneviève S; Bennett, Elena M

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.

We investigate the impact of the Montreal Protocol, and associated phase-out of ozone-depleting substances (ODSs), on the surface mass balance (SMB) of Antarctica, using simulations from the Community Earth System Model-Whole Atmosphere Community Climate Model (CESM-WACCM). The effect of ODSs on Antarctic SMB is first established by contrasting two sets of WACCM integrations (each with 6 ensemble members) for the period 1956-2005: one set that includes the full suite of natural and anthropogenic forcings, and a second set identical to the first but with atmospheric concentrations of ODSs held fixed at year 1955 levels. We find that holding ODSs fixed reduces the simulated increase in Antarctic SMB by nearly 60% in the ensemble mean, due to a suppression of Antarctic-mean warming. Having established this SMB impact of ODSs, we next examine three sets of future WACCM integrations (each with 3 ensemble members) for the period 2006-2065. The first two of these are the CMIP5 RCP4.5 and RCP8.5 integrations that include decreases in ODSs due to the implementation of the Montreal Protocol, and increases in other well-mixed greenhouse gases such as CO2. The third set of future integrations represents a hypothetical "world avoided" scenario in which the Montreal Protocol is assumed to have never been implemented, resulting in drastic increases in ODSs during the next several decades. In the world avoided, the simulated increase in Antarctic SMB is substantially larger than the other two scenarios, exceeding the SMB increases occurring under RCP4.5 and RCP8.5 by a factor of 3.7 and 1.9, respectively. The implications of this for future global sea-level rise will be discussed.

Background Only about 30% of cases of breast cancer can be explained by accepted risk factors. Occupational studies have shown associations between the incidence of breast cancer and exposure to contaminants that are found in ambient air. Objectives We sought to determine whether the incidence of postmenopausal breast cancer is associated with exposure to urban air pollution. Methods We used data from a case–control study conducted in Montreal, Quebec, in 1996–1997. Cases were 383 women with incident invasive breast cancer, and controls were 416 women with other incident, malignant cancers, excluding those potentially associated with selected occupational exposures. Concentrations of nitrogen dioxide (NO2) were measured across Montreal in 2005–2006. We developed a land-use regression model to predict concentrations of NO2 across Montreal for 2006, and developed two methods to extrapolate the estimates to 1985 and 1996. We linked these estimates to addresses of residences of subjects at time of interview. We used unconditional logistic regression to adjust for accepted and suspected risk factors and occupational exposures. Results For each increase of 5 ppb NO2 estimated in 1996, the adjusted odds ratio was 1.31 (95% confidence interval, 1.00–1.71). Although the size of effect varied somewhat across periods, we found an increased risk of approximately 25% for every increase of 5 ppb in exposure. Conclusions We found evidence of an association between the incidence of postmenopausal breast cancer and exposure to ambient concentrations of NO2. Further studies are needed to confirm whether NO2 or other components of traffic-related pollution are indeed associated with increased risks. PMID:20923746

The 'trickle-down effect', or how major sports events have a positive impact on sports participation, has been the subject of many studies, but none produced conclusive results. We took a different approach and rather than look at sports participation, we used injuries as a proxy and see if injuries increased, or remained the same, after the International Federation of Association Football World Cup. Using a retrospective cohort design, we looked at the injuries suffered by males and females (13-16 years old) while playing team sports in Montreal, that occurred in May to July, from 1999 to 2014. Information reported by the Canadian Hospitals Injury Reporting Prevention Program (CHIRPP) was limited to the two CHIRPP centres in Montreal: the Montreal Children's Hospital and Hopital Sainte-Justine. In females, no significant trends were noticed. In males who played non-organised soccer, the percent changes between FIFA World Cup (WC) (June) and pre-FIFA WC (May) was always highest during FIFA WC years: 17.2% more injuries in years when FIFA WC was held compared to 1.3% less injuries during non-FIFA WC years. In non-organised soccer, male players suffered less strains/sprains (11.9% vs. 30.1%; P = 0.015), suffered more severe injuries (59.7% vs. 43.1%; P = 0.049) and more of their injuries were the results of direct contact with another player (26.8% vs. 13.3%; P = 0.028) during FIFA WC. FIFA WC seems to have an impact on the injuries of teenage boys when playing non-organised soccer. The impact was short-lived, only lasting during the FIFA WC event. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Staff rotation: implications for occupational therapy.

Occupational therapy departments of tertiary care hospitals can provide staff with opportunities to gain diverse clinical experience if they rotate through the various services such as surgery, medicine, geriatrics, plastic surgery and orthopaedics. The system of rotation offers both advantages and disadvantages for the staff and the institution. The Royal Victoria Hospital in Montreal, a large university teaching hospital, had traditionally offered staff the opportunity to rotate. Changes in staffing and their needs however, resulted in rotation becoming an important issue within the department. This article presents the pros and the cons of rotation and non-rotation systems as identified by therapists and administrators across Canada. Staff rotation was found to have an effect on job satisfaction and a therapist's career orientation. Given these findings, administrators may want to reconsider the role of the generalist and specialist in their facilities.

In this paper we construct new simple and composed B-splines on the uniform four directional mesh of the plane, in order to improve the approximation order of B-splines studied in Sablonniere (in: Program on Spline Functions and the Theory of Wavelets, Proceedings and Lecture Notes, Vol. 17, University of Montreal, 1998, pp. 67-78). If φ is such a simple B-spline, we first determine the space of polynomials with maximal total degree included in , and we prove some results concerning the linear independence of the family . Next, we show that the cardinal interpolation with φ is correct and we study in S(φ) a Lagrange interpolation problem. Finally, we define composed B-splines by repeated convolution of φ with the characteristic functions of a square or a lozenge, and we give some of their properties.

2016-11-01

The sexual transmission of enteric diseases poses an important public health challenge. We aimed to build a prediction model capable of identifying individuals with a reported enteric disease who could be at risk of acquiring future sexually transmitted infections (STIs). Passive surveillance data on Montreal residents with at least 1 enteric disease report was used to construct the prediction model. Cases were defined as all subjects with at least 1 STI report following their initial enteric disease episode. A final logistic regression prediction model was chosen using forward stepwise selection. The prediction model with the greatest validity included age, sex, residential location, number of STI episodes experienced prior to the first enteric disease episode, type of enteric disease acquired, and an interaction term between age and male sex. This model had an area under the curve of 0.77 and had acceptable calibration. A coordinated public health response to the sexual transmission of enteric diseases requires that a distinction be made between cases of enteric diseases transmitted through sexual activity from those transmitted through contaminated food or water. A prediction model can aid public health officials in identifying individuals who may have a higher risk of sexually acquiring a reportable disease. Once identified, these individuals could receive specialized intervention to prevent future infection. The information produced from a prediction model capable of identifying higher risk individuals can be used to guide efforts in investigating and controlling reported cases of enteric diseases and STIs. © The Author 2016.

2016-12-01

Food insecurity is steadily increasing in Canada. The objective of this paper is to determine if food capacities and satisfaction of recently enrolled participants in food security interventions are associated with the intervention having either a traditional or an alternative type of approach. Participants having recently accessed traditional (n = 711) or alternative community interventions (n = 113) in the Montreal metropolitan area, Canada, were interviewed with a questionnaire. The categorizing variable was participation in a community organization providing either traditional interventions, aimed to help people cope with the urgent need of food, or alternative interventions, aimed at first assistance, in addition to the creation of long-term solutions such as social integration and skills development. Participants' food and nutrition-related capacities and food satisfaction are studied. Multilevel regression models were used to assess whether participants took part in a traditional or alternative interventions. These interventions do not reach the same population. Relative to participants in alternative food security interventions, participants in traditional interventions demonstrated less capacity for accessing information about food safety and healthiness, and perceived their diet as less healthy. Traditional food security participants also paid less attention to the nutritional properties of food and reported less satisfaction with quantity, variety and taste of the food they accessed. The reasons why individuals who may benefit the most from alternative interventions were unlikely to participate should be investigated. The potential that food security interventions may inadvertently reinforce social inequalities in health should be considered in future intervention research. © The Author 2015.

2014-10-01

The organization of basic functions of the human brain, particularly in the right hemisphere, remains poorly understood. Recent advances in functional neuroimaging have improved our understanding of cortical organization but do not allow for direct interrogation or determination of essential (versus participatory) cortical regions. Direct cortical stimulation represents a unique opportunity to provide novel insights into the functional distribution of critical epicentres. Direct cortical stimulation (bipolar, 60 Hz, 1-ms pulse) was performed in 165 consecutive patients undergoing awake mapping for resection of low-grade gliomas. Tasks included motor, sensory, counting, and picture naming. Stimulation sites eliciting positive (sensory/motor) or negative (speech arrest, dysarthria, anomia, phonological and semantic paraphasias) findings were recorded and mapped onto a standard Montreal Neurological Institute brain atlas. Montreal Neurological Institute-space functional data were subjected to cluster analysis algorithms (K-means, partition around medioids, hierarchical Ward) to elucidate crucial network epicentres. Sensorimotor function was observed in the pre/post-central gyri as expected. Articulation epicentres were also found within the pre/post-central gyri. However, speech arrest localized to ventral premotor cortex, not the classical Broca's area. Anomia/paraphasia data demonstrated foci not only within classical Wernicke's area but also within the middle and inferior frontal gyri. We report the first bilateral probabilistic map for crucial cortical epicentres of human brain functions in the right and left hemispheres, including sensory, motor, and language (speech, articulation, phonology and semantics). These data challenge classical theories of brain organization (e.g. Broca's area as speech output region) and provide a distributed framework for future studies of neural networks. © The Author (2014).

The aim of this pilot study was to assess attention deficits in patients with aneurysmal subarachnoid hemorrhage using the test of variables of attention (TOVA). This is a computer-based continuous performance test providing objective measures of attention. We also compared the TOVA results with the attention and concentration domains of Montgomery Åsberg Depression Rating Scale and Montreal cognitive assessment, 2 examiner-administrated neuropsychological instruments. Nineteen patients with moderate to good recovery (Glasgow outcome scale, 4-5) were assessed using the TOVA, Montgomery Åsberg Depression Rating Scale, and Montreal cognitive assessment. The measurements were done when the patients visited the hospital for a routine magnetic resonance imaging control of the aneurysm. TOVA performance was pathological in 58%. The dominating pattern was a worsening of performance in the second half of the test, commonly a failing to react to correct stimuli. We found no correlation between TOVA and the performance in concentration and attention domains of Montgomery Åsberg Depression Rating Scale and Montreal cognitive assessment. Attention deficits, measured by the TOVA, were common after subarachnoid hemorrhage. This should be further studied to improve outcome. © 2015 American Heart Association, Inc.

The Montreal Protocol for Identification of Amusia.

The Montreal Battery for the Evaluation of Amusia (MBEA; Peretz, Champod, & Hyde Annals of the New York Academy of Sciences, 999, 58-75, 2003) is an empirically grounded quantitative tool that is widely used to identify individuals with congenital amusia. The use of such a standardized measure ensures that the individuals tested will conform to a specific neuropsychological profile, allowing for comparisons across studies and research groups. Recently, a number of researchers have published credible critiques of the usefulness of the MBEA as a diagnostic tool for amusia. Here we argue that the MBEA and its online counterpart, the AMUSIA tests (Peretz et al. Music Perception, 25, 331-343, 2008), should be considered steps in a screening process for amusia, rather than standalone diagnostic tools. The goal of this article is to present, in detailed and easily replicable format, the full protocol through which congenital amusics should be identified. In providing information that has often gone unreported in published articles, we aim to clarify the strengths and limitations of the MBEA and to make recommendations for its continued use by the research community as part of the Montreal Protocol for Identification of Amusia.

The Montreal-Toulouse Language Assessment Battery - Brazilian version (MTL-BR) provides a general description of language processing and related components in adults with brain injury. The present study aimed at verifying the criterion-related validity of the Montreal-Toulouse Language Assessment Battery - Brazilian version (MTL-BR) by assessing its ability to discriminate between individuals with unilateral brain damage with and without aphasia. The investigation was carried out in a Brazilian community-based sample of 104 adults, divided into four groups: 26 participants with left hemisphere damage (LHD) with aphasia, 25 participants with right hemisphere damage (RHD), 28 with LHD non-aphasic, and 25 healthy adults. There were significant differences between patients with aphasia and the other groups on most total and subtotal scores on MTL-BR tasks. The results showed strong criterion-related validity evidence for the MTL-BR Battery, and provided important information regarding hemispheric specialization and interhemispheric cooperation. Future research is required to search for additional evidence of sensitivity, specificity and validity of the MTL-BR in samples with different types of aphasia and degrees of language impairment.

A structurally simple, 35-km-thick, north facing stratigraphic succession of Late Archean to Middle Proterozoic rocks is exposed near the Montreal River, which forms the border between northern Wisconsin and Michigan. This structure, the Montreal River monocline, is composed of steeply dipping to vertical sedimentary rocks and flood basalts of the Keweenawan Supergroup (Middle Proterozoic) along the south limb of the Midcontinent rift, and disconformably underlying sedimentary rocks of the Marquette Range Supergroup (Early Proterozoic). These rocks lie on an Archean granite-greenstone complex, about 10 km of which is included in the monocline. This remarkable thickness of rocks appears to be essentially structurally intact and lacks evidence of tectonic thickening or repetition.Tilting to form the monocline resulted from southward thrusting on listric faults of crustal dimension. The faults responsible for the monocline are newly recognized components of a well-known regional fault system that partly closed and inverted the Midcontinent rift system. Resetting of biotite ages on the upper plate of the faults indicates that faulting and uplift occurred at about 1060 +/−20 Ma and followed very shortly after extension that formed the Midcontinent rift system.

Background. Physical activity initiation and maintenance are particular challenges in the postmastectomy recovery and in particular Dragon Boat racing seems to be a useful sport activity. The aim of this study was to evaluate the role of focal muscle vibration as a proprioceptive input to improve upper limb functioning in a group of “paddlers” patients. Methods. A group of paddlers has been evaluated before vibratory treatment (T0), immediately after therapy (T1), after one week (T2), and after one month (T3) with DASH questionnaire, Body Image Scale, McGill pain questionnaire, Constant Scale, and Short Form 36 questionnaire. Results. Fourteen patients showed a significant reduction in disability score (p = 0,001) using DASH scale, an improvement of upper limb function (p = 0,001) using the Constant scale, and a reduction of pain (p = 0,007) at the McGill pain questionnaire. The Mental Composite Score of the Short Form 36 questionnaire showed significant results (p = 0,04) while no significant results had been found regarding the physical mental score (p = 0,08). Conclusion. Focal muscle vibration may be a useful treatment in a postmastectomy recovery of upper limb functionality. PMID:28459068

Descriptive study that proposed to compare the qualitative and quantitative behavior of the pain in lateral posterior thoracotomy patients. The sample was consisted of 18 individuals with an average age of 44 years. The instruments used were physiotherapy evaluation form, numerical pain scale and McGill questionnaire for pain. The pain on the numerical pain scale was considered moderate(5) for both sexes. The descriptors of the McGill questionnaire choosen by the patients with higher frequency were: in the sensorial component, beat4, pointed1, shock2, final and pull2; in the afetive component, tired1, bored1, punishald1 and miserable1 and in the evaluative component was flat. The characteristics of pain in the sensorial group were more evidents on male group. No significant statistical difeferences were observed between quantitative answers concerning pain between the men and women. On the qualitative aspects , was observed an predominancy of the same descriptors of pain in afetive component for both sexes. Pain intensity was categorized as moderate. No significant statistical difference were observed between the pain on the post-operatory lateral posterior thoracotomy. These data demonstrate a necessity for an analysis with a larger study group.

Uninvestigated dyspepsia (UD), irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD) are common disorders universally. Many studies have assessed their epidemiological characteristics around the world. However, such information is not known for Syria. We aim to estimate the epidemiologic characteristics and possible risk factors for UD, IBS, and GERD among students at Damascus University, Damascus, Syria. A cross-sectional study was conducted in July-September 2015 at a campus of Damascus University. A total of 320 students were randomly asked to complete the survey. We used ROME III criteria to define UD and IBS, and Montreal definition for GERD. In total, 302 valid participants were included in the analysis. Prevalence for UD, IBS, and GERD was 25%, 17%, and 16%, respectively. Symptom overlap was present in 46 students (15%), with UD+IBS in 28 (9.3%), UD+GERD in 26 (8.6%), and IBS+GERD in 14 (4.6%) students. Eleven (3.6%) students had symptoms of UD+IBS+GERD. Each of these overlaps occurred more frequently than expected by chance. Significant risk factors included cigarettes smoking, waterpipe consumption, and body mass index <18.5kg/m 2 for UD; female gender and three cups of coffee/d for IBS; and two cups of tea and one to five cigarettes/d for GERD. Risk factors for these disorders remain poorly characterized and need further investigations. Copyright © 2016 Ministry of Health, Saudi Arabia. Published by Elsevier Ltd. All rights reserved.

Many individuals suffer from various kinds of chronic pain. Some controlled studies on distant healing for chronic pain exist, but no definitive conclusion has been established. To study the effects of distant healing performed by a professional Japanese healer on chronic pain. A double-blind randomized controlled study. Holos University, Fair Grove, Missouri. People suffering from chronic pain (not caused by clear organic diseases or that persists long after a reasonable period of healing following injuries or surgery) were recruited through local radio and newspaper advertising. Subjects were randomly assigned to a treatment group or control group using a double-blind procedure. All subjects met the healer at the initial session at Holos University. At the session, a 20-minute group meditation was performed. The healer went back to Japan after the session and started distant healing only to the treatment group for a 2-month period. All participants were asked to meditate for 20 minutes every day during this 2-month period. The visual analog scale and McGill Pain Questionnaire. A total of 17 subjects were recruited, and 16 subjects completed the study. Comparison of pretreatment and posttreatment visual analog scale indicated a slightly significant effect of distant healing (P=.056). The Present Pain Intensity Scale showed significant improvement in the treatment group compared to the control group (P=.0016). The Pain Rating Index showed improvement in the treatment group, but the difference between both groups was not statistically significant (P=.12).

Collaborative relationships are influenced by the context of the organization in which health professionals work. There is limited knowledge concerning the influence that organizational factors have on this process. A descriptive study design using semistructured interviews was used to explore nurses' perceptions of the organizational factors that influence the development of collaborative relationships in health care teams. Eight nurses from a university-affiliated teaching hospital in Montreal participated in this study. Nurses described a variety of experiences where effective collaboration took place. One common theme emerged from the participants: Being Available for Collaboration. Nurses perceived that 2 particular organizational factors-time and workday scheduling-influenced the development of collaborative relationships. This study supports the need for health care managers to promote and invest in alternative means of communication technology and to structure clinical care environments to help promote the development of collaborative relationships within health care teams.

Hans Selye, the father of the stress concept, was a giant of science of the twentieth century. Beyond his best-known work on stress, he also made several discoveries on various other fields of experimental medicine. He described and characterized various pluricausal diseases. In addition, he made pivotal contributions to the broad field of endocrinology, especially to the classification of steroids and to our better understanding of their mode of action. He developed surgical technics and experimental animal models suitable for studying the pathogenesis and prevention of human diseases. Selye was an extremely well educated, highly intelligent and disciplined individual, an original and creative scientist, an outstanding teacher, a philosopher, a prolific author, a fabulous communicator and a gifted organizer successfully establishing, developing and managing a major academic research institution, the word-famous Institute of Experimental Medicine and Surgery of the University of Montreal.

This article examines the story of the Assistance maternelle de Montreal, an organization founded in 1912 by a group of bourgeois catholic women to provide material assistance and free medical services to poor pregnant mothers of the city. I want to show that even if the timid intervention of the Quebec state allowed the AM to survive during the almost 50 years, the rise of the experts in the health field--a phenomenon to which the AM has largely contributed--and in the philanthropic sector led to the marginalization of the female volunteers within the very institution they had created.

We present Beauty and The Beast, a new polarimeter of the Universite de Montreal, formerly built for the Canada-France-Hawaii telescope (CFHT) but never commissioned there. 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)

Despite widespread use, there have been few investigations into the neuroanatomical correlates of the Montreal Cognitive Assessment (MoCA). In a sample of 138 consecutive patients presenting with cognitive complaints, we report significant correlations between lower MoCA memory scores and smaller hippocampal volumes (r = 0.36–0.41, p < 0.001). We also report that the newly devised memory index score, designed to better capture encoding deficits than the standard delayed recall score, was not significantly better for predicting hippocampal volume. These initial results suggest that poor performance on the MoCA’s memory section should prompt further evaluation for hippocampal atrophy. PMID:28453481

Bronchial typical carcinoid tumors are rare. The "gold standard" treatment is surgery, but there is literature to support bronchoscopic therapy with curative intent. Based on the efficacy of cryotherapy for in situ lung cancer, we studied the safety and efficacy of rigid bronchoscopic treatment with cryotherapy on isolated endoluminal typical carcinoid tumors. All the patients from the Department of Pulmonary Diseases and Thoracic Oncology of St. Etienne University Hospital (France), and of Hôpital Notre Dame, University Hospital of Montreal referred with typical carcinoid were screened. Inclusion criteria included the following: proven typical carcinoid, strictly endoluminal disease amenable to bronchoscopic therapy, and no evidence of lymph node invasion. All patients had a complete removal of the tumor, and all patients received cryotherapy to the implantation base. Twenty-nine patients were screened, and 18 were included. Mean age was 47 years, and study population included 11 women. Median follow-up was 55 months. There was a single recurrence 7 years after the initial bronchoscopic treatment. Cryotherapy is a safe and effective adjunct to endobronchial mechanical resection of typical carcinoids. Unlike other adjuncts that have been proposed, cryotherapy is not associated with long-term complications including bronchial stenosis.

Effects of a Comprehensive Police Suicide Prevention Program

PubMed Central

Mishara, Brian L.; Martin, Normand

2012-01-01

Background: Police suicides are an important problem, and many police forces have high rates. Montreal police suicide rates were slightly higher than other Quebec police rates in the 11 years before the program began (30.5/100,000 per year vs. 26.0/100,000). Aims: To evaluate Together for Life, a suicide prevention program for the Montreal police. Methods: All 4,178 members of the Montreal police participated. The program involved training for all officers, supervisors, and union representatives as well as establishing a volunteer helpline and a publicity campaign. Outcome measures included suicide rates, pre-post assessments of learning, focus groups, interviews, and follow-up of supervisors. Results: In the 12 years since the program began the suicide rate decreased by 79% (6.4/100,000), while other Quebec police rates had a nonsignificant (11%) increase (29.0/100,000). Also, knowledge increased, supervisors engaged in effective interventions, and the activities were highly appreciated. Limitations: Possibly some unidentified factors unrelated to the program could have influenced the observed changes. Conclusions: The decrease in suicides appears to be related to this program since suicide rates for comparable populations did not decrease and there were no major changes in functioning, training, or recruitment to explain the differences. Comprehensive suicide prevention programs tailored to the work environment may significantly impact suicide rates. PMID:22450038

In order to properly assess language, sociodemographic variables that can influence the linguistic performance of individuals with or without linguistic disorders need to be taken into account. The aim of this study was to evaluate the influence of schooling and age on the results from the Montreal Toulouse (Modified MT Beta-86) language assessment test among individuals without linguistic disorders. Cross-sectional study carried out between March 2006 and August 2007 in the Speech, Language and Hearing Pathology Department of Universidade Federal de São Paulo (Unifesp), São Paulo, Brazil. Eighty volunteers were selected. Schooling was stratified into three bands: A (1-4 years), B (5-8 years) and C (nine years and over). The age range was from 17 to 80 years. All the subjects underwent the Montreal Toulouse (Modified MT Beta-86) language assessment protocol. Statistically significant differences were found in relation to schooling levels, in the tasks of oral comprehension, reading, graphical comprehension, naming, lexical availability, dictation, graphical naming of actions and number reading. Statistically significant age-related differences in dictation and lexical availability tasks were observed. The Montreal Toulouse (Modified MT Beta-86) test seems to be sensitive to variations in schooling and age. These variables should be taken into account when this test is used for assessing patients with brain damage.

The present study introduces a novel tool for assessing musical abilities in children: The Montreal Battery of Evaluation of Musical Abilities (MBEMA). The battery, which comprises tests of memory, scale, contour, interval, and rhythm, was administered to 245 children in Montreal and 91 in Beijing (Experiment 1), and an abbreviated version was administered to an additional 85 children in Montreal (in less than 20 min; Experiment 2). All children were 6–8 years of age. Their performance indicated that both versions of the MBEMA are sensitive to individual differences and to musical training. The sensitivity of the tests extends to Mandarin-speaking children despite the fact that they show enhanced performance relative to French-speaking children. Because this Chinese advantage is not limited to musical pitch but extends to rhythm and memory, it is unlikely that it results from early exposure to a tonal language. In both cultures and versions of the tests, amount of musical practice predicts performance. Thus, the MBEMA can serve as an objective, short and up-to-date test of musical abilities in a variety of situations, from the identification of children with musical difficulties to the assessment of the effects of musical training in typically developing children of different cultures.

Revising the formal, retrieving the hidden: Undergraduate curricular reform in medicine and the scientific, institutional, & social transformation of the clinical training environment

NASA Astrophysics Data System (ADS)

Jagosh, Justin J.

2009-12-01

In 2004, members of the McGill University Faculty of Medicine began implementing a new curriculum for undergraduate medical education entitled, Physicianship: The Physician as Professional and Healer. The initiative underscores the idea that physician training entails cultivating not only scientific knowledge and technical skill, but a mindset guided by intrinsic principles of doctoring. Although the McGill case exemplifies a wide-spread paradigm shift in medical teaching, there is a dearth of analysis concerning the degree of congruency between the objectives of formal undergraduate curricular revision and the so-called 'hidden curriculum' of the hospital training environment. With Physicianship as a point of departure, this dissertation maps evolutionary patterns in clinical medicine and, using qualitative methods, analyzes the perspectives of twenty physician-educators on curricular reform and the transforming clinical training environment. Physicians interviewed were generally supportive of the new curricular initiative. Concerns were raised, however, that many recent changes within the teaching hospital environment interfere with students' cultivation of professional and healer attributes. These changes were organized into three main themes: scientific, institutional, and social. Physicians expressed concern that what is often considered beneficial for patients is often detrimental for medical training. For example, increased use of diagnostic technologies has improved patient care but reduces opportunities for trainees' clinical skill development. Concern was raised that the concept of selfless service has been undermined through recent shift-work regulations and a culture gap between older and younger generation physicians. Alternatively, some perceived new policies of the clinical environment to be more conducive to physicians' self-care and quality of life. Younger trainees were often described as more competent in managing medical information, more open to diversity, more candid about their needs, and more apt to challenge dogmatic or ethically substandard practices. The complexity of the transforming clinical environment is used to justify a rationale for developing the concept of Phronesis (practical wisdom) as a pedagogical framework. The concepts of 'acuity of perception' and 'mastery of emotion' are grounded in the data and analyzed for the development of Phronesis, to advance the field of medical education and support curricular initiatives such as the Physicianship program.

Recent trends in global emissions of hydrochlorofluorocarbons and hydrofluorocarbons: reflecting on the 2007 adjustments to the Montreal Protocol.

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.

In the eye of the beholder: Assessing the water quality of shoreline parks around the Island of Montreal through citizen science.

As a part of the FreshWater Watch project aiming to promote volunteers' water monitoring in 25 cities around the world, St. Lawrence River water quality was characterized at 28 public shoreline parks around Montreal Island, Quebec, Canada. This involved training of 69 citizen scientists by researchers of the Université de Montréal in five one-day sessions. Shoreline sampling yielded 174 data points over three summers (May 2013 to November 2015). Water turbidity, nitrate and phosphate concentrations were measured in situ, together with the thickness and type of beach-cast vegetation, and the relative abundance of different types of beach litter. Data generated by citizen scientists provided 1) an overview of the water quality of the St. Lawrence and Des Prairies rivers around the Island of Montreal, 2) an estimation of the quantity and types of beach-cast aquatic plants and filamentous algae, and 3) novel insights into the distribution of the nuisance cyanobacterium Lyngbya wollei. Overall, half of the sites were classified as "good" being characterized by low turbidity, nitrate and phosphate concentrations, and little deposition of beach-cast vegetation. Lyngbya wollei was found at 57% of the sites, revealing a more frequent occurrence than initially anticipated. The amount of litter recorded along the shoreline was generally small, comprising items related to picnicking (cans/bottles), smoking, and fishing activities in most parks. Wind exposure and rain events explained a significant fraction of the variability in nutrient concentration and turbidity among sites and dates. Shoreline condition assessed from water quality and vegetation data from this study was not correlated, however, with the most serious problem of faecal coliform counts gathered by the City of Montreal. This assessment of the quality and utilization of shoreline parks provides additional information to support planning and management activities of municipalities. Crown Copyright © 2016.

Tran, Nathalie Y L; Charbonneau, Johanne; Valderrama-Benitez, Valeria

2013-01-01

Through the conceptual lens of the archaic and modern gift, this study aims to examine perceived limitations and facilitators to increasing blood donations within Black communities in Montreal, Canada. The overall objective is to support blood agencies, such as Héma-Québec, in understanding the challenges and opportunities they face in promoting blood donation among Black communities in pluralistic societies. Thirty-three semi-structured qualitative interviews were conducted with donors and leaders of ethnocultural groups in Montreal: of these, 6 were Héma-Québec employees; 3 were Caribbean blood drive organizers; 14 were leaders of African, Caribbean or Black multiethnic churches and community groups; and finally, 10 were donors, including 2 African, 4 French-speaking Haitian and 4 English-speaking Caribbean. The existence of multiple Black communities in Montreal reflects the various facilitators and obstacles facing Héma-Québec. Caribbean and African communities have their own experiences with regard to blood donation as well as different relationships with the broader Quebec society, both of which have great impact on how they perceive the cause. Questions of trust, of giving to the family and to the community, as well as perceived social exclusion appear to be fundamental issues for our informants. The current participation of groups interested in bettering the lives of those affected by sickle cell anaemia combined with the fact that leaders felt more comfortable donating to someone close to the community suggests that the promotion of blood donation through this angle would be well received. Trust issues, perceived discrimination and social exclusion have structural and historical roots that can only be partly overcome with long-term efforts to increase awareness, develop collaborative partnerships and increase institutional efforts to adapt to the challenges of blood donation from Black citizens.

HCFC-142b emissions in China: An inventory for 2000 to 2050 basing on bottom-up and top-down methods

1-Chloro-1,1-difluoroethane (HCFC-142b) is both ozone depleting substance included in the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) and potent greenhouse gas with high global warming potential. As one of the major HCFC-142b consumption and production countries in the world, China's control action will contribute to both mitigating climate change and protecting ozone layer. Estimating China's HCFC-142b emission is a crucial step for understanding its emission status, drawing up phasing-out plan and evaluating mitigation effect. Both the bottom-up and top-down method were adopted in this research to estimate HCFC-142b emissions from China. Results basing on different methods were compared to test the effectiveness of two methods and validate inventory's reliability. Firstly, a national bottom-up emission inventory of HCFC-142b for China during 2000-2012 was established based on the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and the Montreal Protocol, showing that in contrast to the downward trend revealed by existing results, HCFC-142b emissions kept increasing from 0.1 kt/yr in 2000 to the peak of 14.4 kt/yr in 2012. Meanwhile a top-down emission estimation was also developed using interspecies correlation method. By correlating atmospheric mixing ratio data of HCFC-142b and reference substance HCFC-22 sampled from four representative cities (Beijing, Hangzhou, Lanzhou and Guangzhou, for northern, eastern, western and southern China, respectively), China's HCFC-142b emission in 2012 was calculated. It was 16.24(13.90-18.58) kt, equivalent to 1.06 kt ODP and 37 Tg CO2-eq, taking up 9.78% (ODP) of total HCFCs emission in China or 30.5% of global HCFC-142b emission. This result was 12.7% higher than that in bottom-up inventory. Possible explanations were discussed. The consistency of two results lend credit to methods effectiveness and results reliability. Finally, future HCFC-142b emission was projected to 2050. Emission might experience a continuous increase from 14.9 kt/yr to 97.2 kt/yr under business-as-usual (BAU) scenario, while a 90% reduction would be obtained by fulfilling the Montreal Protocol, namely an accumulative mitigation of 1578 kt from 2013 to 2050, equal to 103 kt ODP, and 3504 Tg CO2 emissions. Therefore, China will contribute tremendously to the worldwide ozone protection and global warming mitigation by successfully phasing out HCFC-142b according to the Montreal Protocol schedule.

Parkinson disease dementia dramatically increases mortality rates, patient expenditures, hospitalization risk, and caregiver burden. Currently, predicting Parkinson disease dementia risk is difficult, particularly in an office-based setting, without extensive biomarker testing. To appraise the predictive validity of the Montreal Parkinson Risk of Dementia Scale, an office-based screening tool consisting of 8 items that are simply assessed. This multicenter study (Montreal, Canada; Tottori, Japan; and Parkinson Progression Markers Initiative sites) used 4 diverse Parkinson disease cohorts with a prospective 4.4-year follow-up. A total of 717 patients with Parkinson disease were recruited between May 2005 and June 2016. Of these, 607 were dementia-free at baseline and followed-up for 1 year or more and so were included. The association of individual baseline scale variables with eventual dementia risk was calculated. Participants were then randomly split into cohorts to investigate weighting and determine the scale's optimal cutoff point. Receiver operating characteristic curves were calculated and correlations with selected biomarkers were investigated. Dementia, as defined by Movement Disorder Society level I criteria. Of the 607 patients (mean [SD] age, 63.4 [10.1]; 376 men [62%]), 70 (11.5%) converted to dementia. All 8 items of the Montreal Parkinson Risk of Dementia Scale independently predicted dementia development at the 5% significance level. The annual conversion rate to dementia in the high-risk group (score, >5) was 14.9% compared with 5.8% in the intermediate group (score, 4-5) and 0.6% in the low-risk group (score, 0-3). The weighting procedure conferred no significant advantage. Overall predictive validity by the area under the receiver operating characteristic curve was 0.877 (95% CI, 0.829-0.924) across all cohorts. A cutoff of 4 or greater yielded a sensitivity of 77.1% (95% CI, 65.6-86.3) and a specificity of 87.2% (95% CI, 84.1-89.9), with a positive predictive value (as of 4.4 years) of 43.90% (95% CI, 37.76-50.24) and a negative predictive value of 96.70% (95% CI, 95.01-97.85). Positive and negative likelihood ratios were 5.94 (95% CI, 4.08-8.65) and 0.26 (95% CI, 0.17-0.40), respectively. Scale results correlated with markers of Alzheimer pathology and neuropsychological test results. Despite its simplicity, the Montreal Parkinson Risk of Dementia Scale demonstrated predictive validity equal or greater to previously described algorithms using biomarker assessments. Future studies using head-to-head comparisons or refinement of weighting would be of interest.

Medical schools are confronted with the challenge of teaching professionalism during medical training. The aim of this study was to examine medical students' perceptions of using video clips as a beneficial teaching tool to learn professionalism and other aspects of physicianship. As part of the longitudinal Physician Apprenticeship course at McGill University, first year medical students viewed video clips from the television series ER. The study used qualitative description and thematic analysis to interpret responses to questionnaires, which explored the educational merits of this exercise. Completed questionnaires were submitted by 112 students from 21 small groups. A major theme concerned the students' perceptions of the utility of video clips as a teaching tool, and consisted of comments organized into 10 categories: "authenticity and believability", "thought provoking", "skills and approaches", "setting", "medium", "level of training", "mentorship", "experiential learning", "effectiveness" and "relevance to practice". Another major theme reflected the qualities of physicianship portrayed in video clips, and included seven categories: "patient-centeredness", "communication", "physician-patient relationship", "professionalism", "ethical behavior", "interprofessional practice" and "mentorship". This study demonstrated that students perceived the value of using video clips from a television series as a means of teaching professionalism and other aspects of physicianship.

Cosmic rays have dangerous effects for space, air and ground based assets, but on the other side cosmic rays are direct measure tools for real time space weather warning. A review of space weather related SSA results from operating global cosmic ray networks (especially those by neutron monitors and by muon directional telescopes), its limitations and main questions to be solved, is presented. Especially those recent results, received in real time and with high temporal resolution, are reviewed and discussed. In addition the relevance of these monitors and telescopes in forecasting geomagnetic disturbances are checked. Based on this study result, a next generation of highly miniaturized hybrid silicon pixel device (Medipix sensor) will be described for the following, beyond state-of-the-art application: a SSA satellite for high energy solar and galactic cosmic ray spectrum measurement, with a space plasma environment data package and CME real time imaging by means of cosmic rays. All data management and processing will be carried out on the satellite in real time. Insofar a high reduction of data and transmission to ground station of finalized space weather relevant data and images are foreseen.

The aim of the present study was to characterize pain in breast cancer survivors using the McGill Pain Questionnaire (MPQ). A descriptive, cross-sectional study was conducted with 30 women aged 30-80 years who had been submitted to treatment for breast cancer (surgery and complementary treatment) at least 12 months earlier with reports of pain related to the therapeutic procedures. Pain was characterized using the full-length version of the MPQ, which is made up of 78 descriptors divided into four categories: sensory (ten items), affective (five items), evaluative (one item) and miscellaneous (four items). Two indices were also used to measure pain through the use of the descriptors: the number of words chosen (NWC) and the pain rating index (PRI). The most frequent descriptive terms were "agonizing" (n = 16; 53.3%), "tugging" (n = 15; 50%), "sore" (n = 14; 46.7%), "wretched" (n = 14; 46.7%), "troublesome" (n = 13; 43.3%) and "spreading" (n = 11; 36.7%). The sensory category had the highest PRI value based on the descriptors chosen (mean: 0.41). Women with chronic pain following treatment for breast cancer employed the "agonizing", "tugging" and "sore" descriptors with greatest frequency and rated pain in the sensory category as having the greatest impact.

OBJECTIVE: To describe family physicians' perceived educational needs in computers and informatics. DESIGN: Mailed survey. SETTING: General or family practices in Canada. PARTICIPANTS: Physicians (489 responded to a mailing sent to 2,500 physicians) who might attend sessions at the McGill Centre for CME. Two duplicate questionnaires were excluded from the analysis. METHOD: Four domains were addressed: practice profile, clinical CME needs, professional CME needs, and preferred learning formats. Data were entered on dBASE IV; analyses were performed on SPSS. MAIN FINDINGS: In the 487 questionnaires retained for analysis, "informatics and computers" was mentioned more than any other clinical diagnostic area, any other professional area, and all but three patient groups and service areas as a topic where improvement in knowledge and skills was needed in the coming year. Most physicians had no access to computer support for practice (62.6%); physicians caring for neonates, toddlers, or hospital inpatients were more likely to report some type of computer support. CONCLUSIONS: Family physicians selected knowledge and skills for computers and informatics as an area for improvement in the coming year more frequently than they selected most traditional clinical CME topics. This educational need is particularly great in small towns and in settings where some computerized hospital data are already available. PMID:10790816

Nursing patients with acute chest pain: practice guided by the Prince Edward Island conceptual model for nursing.

Current research suggests that pain is a relatively common phenomenon with 60-90% of patients presenting to emergency departments reporting pain (e.g., chest pain, trauma, extremity fractures and migraine headache) that require treatment [Hogan, S.L., 2005. Patient satisfaction with pain management in the emergency department. Advanced Emergency Nursing Journal 27(4), 284-294]. This article explores the use of conceptual theoretical empirical (C-T-E) framework to guide a senior nursing student in a case study of patient with chest pain. The Middle Range Theory of Pain described by Good [Good, M., 1998. A middle-range theory of acute pain management: use in research. Nursing Outlook 46(3), 120-124] and Melzack's [Melzack, R., 1987. The short-form McGill pain questionnaire. Pain, 30, 191-197] short form McGill pain questionnaire were applied along with the Prince Edward Island conceptual model (PEICM) for nursing. Results indicate that the nursing student increased her ability to work in partnership, assess relevant and specific information, and identify a number of strategies to help the patient achieve pain control by using a complement of pharmacological and non-pharmacological interventions. Moreover, the C-T-E approach provided an organized and systematic theoretical approach for the nursing student to assist a patient in pain control.

This study aims to establish psychometric properties of the Malay Neuropsychiatry Unit Cognitive Assessment Tool (Malay NuCOG) in Alzheimer's disease. NuCOG was translated to Malay language and compared with Montreal Cognitive Assessment Tool on 80 individuals. The Malay NuCOG showed good internal consistency and reliability (Cronbach's alpha = 0.895). It demonstrated 100% sensitivity and 87.5% specificity at the cutoff score of 78.50/100. The Malay NuCOG is a valid and reliable cognitive instrument that is sensitive and specific for the detection of dementia and has clinical advantages in its ability to examine individual cognitive domains. © 2015 Wiley Publishing Asia Pty Ltd.

Adaptability of Physicians Offering Primary Care to the Poor: Social Competency Revisited

Loignon, Christine; Boudreault-Fournier,, Alexandrine

2013-01-01

This paper attempts to go deeper into the topic of social competency of physicians who provide primary care to populations living in poverty in Montreal. Adaptability as well as the ability to tailor practices according to patient expectations, needs and capabilities were found to be important in the development of the concept of social competency. The case of paternalism is used to demonstrate how a historically and socially contested medical approach is readapted by players in certain contexts in order to better meet patient expectations. This paper presents data collected in a qualitative study comprising 25 semi-supervised interviews with physicians recognized by their peers as having developed exemplary practices in Montreal's impoverished neighbourhoods.

Cosmic X-rays Reveal Evidence For New Form Of Matter

NASA Astrophysics Data System (ADS)

2002-04-01

NASA's Chandra X-ray Observatory has found two stars -- one too small, one too cold -- that reveal cracks in our understanding of the structure of matter. These discoveries open a new window on nuclear physics, offering a link between the vast cosmos and its tiniest constituents. Chandra's observations of RX J1856.5-3754 and 3C58 suggest that the matter in these stars is even denser than nuclear matter found on Earth. This raises the possibility these stars are composed of pure quarks or contain crystals of sub-nuclear particles that normally have only a fleeting existence following high-energy collisions. By combining Chandra and Hubble Space Telescope data, astronomers found that RX J1856 radiates like a solid body with a temperature of 1.2 million degrees Fahrenheit (700,000 degrees Celsius) and has a diameter of about seven miles (11.3 kilometers). This size is too small to reconcile with standard models for neutron stars -- until now the most extreme form of matter known. "Taken at face value, the combined observational evidence points to a star composed not of neutrons, but of quarks in a form known as strange quark matter," said Jeremy Drake of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., and lead author of a paper on RX J1856 to appear in the June 20, 2002, issue of The Astrophysical Journal. "Quarks, thought to be the fundamental constituents of nuclear particles, have never been seen outside a nucleus in Earth-bound laboratories." Observations by Chandra of 3C58 also yielded startling results. A team composed of Patrick Slane and Steven Murray, also of CfA, and David Helfand of Columbia University, New York, failed to detect the expected X-radiation from the hot surface of 3C58, a neutron star believed to have been created in an explosion witnessed by Chinese and Japanese astronomers in A.D. 1181. The team concluded that the star has a temperature of less than one million degrees Celsius, which is far below the predicted value. 3C58 3C58 "Our observations of 3C58 offer the first compelling test of models for how neutron stars cool, and the standard theory fails," said Helfand. "It appears that neutron stars aren't pure neutrons after all -- new forms of matter are required." A teaspoonful of neutron-star material weighs a billion tons, as much as all the cars, trucks and buses on Earth. Its extraordinary density is equivalent to that of the nucleus of an atom with all the typical space between the atoms and their nuclei removed. An atom's nucleus is composed of positively charged protons and neutral neutrons, particles so small that 100 billion trillion of them would fit on the head of a pin. Protons and neutrons are composed of even smaller particles called quarks, the basic building blocks of matter. Enormous atom-smashers are designed to probe the forces between quarks and the structure of the nucleus by smashing high-energy beams of nuclei into each other and observing the violent aftermath for a fraction of a second. Drake cautioned that the observations of RXJ1856 could be interpreted as a more normal neutron star with a hot spot. Such a model is under consideration by Fred Walter of the State University of New York, Stony Brook, one of the discoverers of RXJ1856, which was originally found in 1996 by the German Roentgen satellite. However, such a model would be expected to pulse, and a team of scientists lead by Scott Ransom of McGill University in Montreal, Canada report in The Astrophysical Journal Letters, that the pulsed fraction of the X-radiation from RX J1856 is less than 5%. To explain the absence of pulsations, a very special orientation with respect to the Earth is required. "Regardless of how these mysteries are resolved, these precise observations are highly significant," said Michael Turner of the University of Chicago. "They demonstrate our ability to use the universe as a laboratory where we can study some of the most fundamental questions in physics."

to evaluate pain in patients with lower limb venous ulcer who used non-adherent Ibuprofen foam dressing (IFD). we conducted a prospective study of patients with lower limb venous ulcers treated from April 2013 to August 2014. We used the Numerical Scale and McGill Pain Questionnaire, performing the assessments at the moment of inclusion of the patient in the study and every eight days thereafter, totaling five consultations. We divided the patients into two groups: 40 in the Study Group (SG), who were treated with IFD, and 40 in the Control Group (CG), treated with primary dressing, according to tissue type and exudate. at the first consultation, patients from both groups reported intense pain. On the fifth day, SG patients reported no pain and the majority of CG reported moderate pain. Regarding the McGill Pain Questionnaire, most patients of both groups reported sensations related to sensory, affective, evaluative and miscellaneous descriptors at the beginning of data collection; after the second assessment, there was slight improvement among the patients in the SG. After the third consultation, they no longer reported the mentioned descriptors. CG patients displayed all the sensations of these descriptors until the fifth visit. non-adherent Ibuprofen foam dressing is effective in reducing the pain of patients with venous ulcers. avaliar a dor em pacientes portadores de úlcera venosa de membros inferiores que utilizaram curativo de espuma não aderente com Ibuprofeno (CEI). estudo prospectivo de pacientes portadores de úlceras venosas de membros inferiores tratados no período de abril de 2013 a agosto de 2014.

Special article: Horace Nelson MD, John Webster LDS--unrecognized Canadian anesthesia pioneers.

PubMed

Craig, Douglas; Chartrand, Daniel

2014-03-01

The timing of the earliest reported ether anesthetics in early 1847, in regions to become Canada in July 1867, was examined using information from on-line and library-based sources. Previous authors had identified the first reported ether anesthetic given by a visiting American dentist in January 1847 in Saint John, New Brunswick. Nevertheless, they had reported three different anesthetics as the second occurrence - which would denote the first anesthetic given by a resident of Canada. We confirmed that there were no reports of ether anesthetics being given in Canada before that reported on January 18, 1847 in Saint John. The information available for our review indicates that the second ether anesthetic, and the first by a Canadian, was given in Montreal by a dentist, Dr. John Horatio Webster, on February 20, 1847. The surgical assistant for that operation, Dr. Horace Nelson, later reported on animal and human experiments with ether, which he had led in Montreal starting in January 1847. Earlier authors, who may not have had access to the information now available, came to incorrect conclusions about the first ether anesthetic reported to have been given by a Canadian. Current information indicates that John Webster gave the first reported anesthetic in Montreal on February 20, 1847 following experiments with ether led by Horace Nelson. Both Webster and Nelson deserve recognition as Canadian anesthesia pioneers.

Crohn's disease (CD) is a chronic inflammation of the gastrointestinal tract associated with life-long high health care costs. We aimed to determine the effect of disease phenotype on cost. Clinical and economic data of a community-based CD cohort with 10-year follow-up were analyzed retrospectively in relation to Montreal classification phenotypes. In 418 patients, mean total costs of health care for the behavior phenotypes were: nonstricturing-nonpenetrating 1690, stricturing 2081, penetrating 3133 and penetrating-with-perianal-fistula 3356 €/patient-phenotype-year (P<0.001), and mean costs of surgical hospitalization 215, 751, 1293 and 1275 €/patient-phenotype-year respectively (P<0.001). Penetrating-with-perianal-fistula patients incurred significantly greater expenses than penetrating patients for total care, diagnosis and drugs, but not surgical hospitalization. Total costs were similar in the location phenotypes: ileum 1893, colon 1748, ileo-colonic 2010 and upper gastrointestinal tract 1758 €/patient-phenotype-year, but surgical hospitalization costs differed significantly, 558, 209, 492 and 542 €/patient-phenotype-year respectively (P<0.001). By multivariate analysis, the behavior phenotype significantly impacted total, medical and surgical hospitalization costs, whereas the location phenotype affected only surgical costs. Younger age at diagnosis predicted greater surgical expenses. Behavior is the dominant phenotype driving health care cost. Use of the Montreal classification permits detection of cost differences caused by perianal fistula.

A Supplementary Emission Control (SEC) system has been developed on behalf of the Association Industrielle de l`Est de Montreal (AIEM). The objective of the SEC is to avoid exceedences of the Montreal Urban Community (MUC) 24 hour ambient Air Quality Standard (AQS) for sulphur dioxide in the industrial East Montreal area. The SEC system is comprised of: 3 continuous SO{sub 2} monitoring stations with data loggers and remote communications; a meteorological tower with data logger and modem for acquiring local meteorology; communications with Environment Canada to download meteorological forecast data; a polling PC for data retrieval; and Windows NT basedmore » software running on the AIEM computer server. The SEC software utilizes relational databases to store and maintain measured SO{sub 2} concentration data, emission data, as well as observed and forecast meteorological data. The SEC system automatically executes a numerical dispersion model to forecast SO{sub 2} concentrations up to six hours in the future. Based on measured SO{sub 2} concentrations at the monitoring stations and the six hour forecast concentrations, the system determines if local sources should reduce their emission levels to avoid potential exceedences of the AQS. The SEC system also includes a Graphical User Interface (GUI) for user access to the system. The SEC system and software are described, and the accuracy of the system at forecasting SO{sub 2} concentrations is examined.« less

In 1997, the Montreal Biodome obtained five barndoor skates (Dipturus laevis) from the waters off Boston, Massachusetts. Six years later, those specimens began reproducing, and the first egg case was collected in November 2003. Since then, 73 hatchlings have been born and raised. Egg cases were observed year round, and annual fecundity was measured for the first time: one female laid 69 eggs in 2005, 85 in 2006 and 115 in 2007. Egg incubation was longer than believed previously, ranging from 342 to 494 days. Hatching occurred throughout the year. Hatchlings averaged 193 mm total length and 128 mm disk width and weighed 32 g. They were fed krill and diced fish. All but one survived the first month. A photo identification system was useful in recognizing two groups of 10 specimens during their first year, and transponders could be inserted in the wing muscles of 1-year-old skates. Total lengths at birth and at age 2 were similar to the data reported from the wild, suggesting a similar growth pattern in captivity. The reproduction characteristics of the barndoor skate were compared with those of two other skate species currently bred at the Montreal Biodome, the winter skate (Leucoraja ocellata) and the thorny skate (Amblyraja radiata).

We seek funding from NASA for the third year (2005) of the four-year period January 1, 2003 - December 31, 2006 for continued support of the MIT contributions to the multi-national global atmospheric trace species measurement program entitled Advanced Global Atmospheric Gases Experiment (AGAGE). The case for real-time high-frequency measurement networks like AGAGE is very strong and the observations and their interpretation are widely recognized for their importance to ozone depletion and climate change studies and to verification issues arising from the Montreal Protocol (ozone) and Kyoto Protocol (climate). The proposed AGAGE program is distinguished by its capability to measure over the globe at high frequency almost all of the important species in the Montreal Protocol and almost all of the significant non-CO2 gases in the Kyoto Protocol.

A Cocoon Found Inside the Black Widow's Web

NASA Astrophysics Data System (ADS)

2003-02-01

NASA's Chandra X-ray Observatory image of the mysterious "Black Widow" pulsar reveals the first direct evidence of an elongated cocoon of high-energy particles. This discovery shows that this billion-year-old rejuvenated pulsar is an extremely efficient generator of a high-speed flow of matter and antimatter particles. Known officially as pulsar B1957+20, the Black Widow received its nickname because it is emitting intense high-energy radiation that is destroying its companion through evaporation. B1957+20, which completes one rotation every 1.6-thousandths of a second, belongs to a class of extremely rapidly rotating neutron stars called millisecond pulsars. The motion of B1957+20 through the galaxy -- at a high speed of almost a million kilometers per hour -- creates a bow shock wave visible to optical telescopes. The Chandra observation shows what cannot be seen in visible light: a second shock wave. This secondary shock wave is created from pressure that sweeps the wind back from the pulsar to form the cocoon of high-energy particles, visible for the first time in the Chandra data. "This is the first detection of a double-shock structure around a pulsar," said Benjamin Stappers, of the Dutch Organization for Research in Astronomy (ASTRON), lead author on a paper describing the research that will appear in the Feb. 28, 2003, issue of Science magazine. "It should enable astronomers to test theories of the dynamics of pulsar winds and their interaction with their environment." B1957+20 X-ray-only image of B1957+20 Scientists believe millisecond pulsars are very old neutron stars that have been spun up by accreting material from their companions. The steady push of the infalling matter on the neutron star spins it up in much the same way as pushing on a merry-go-round makes it rotate faster. The result is an object about 1.5 times as massive as the Sun and ten miles in diameter that rotates hundreds of times per second. The advanced age, very rapid rotation rate and relatively low magnetic field of millisecond pulsars put them in a totally separate class from young pulsars observed in the remnants of supernova explosions. "This star has had an incredible journey. It was born in a supernova explosion as a young and energetic pulsar, but after a few million years grew old and slow and faded from view," said Bryan Gaensler of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., a coauthor of the paper. "Over the next few hundred million years, this dead pulsar had material dumped on it by its companion, and the pulsar's magnetic field has been dramatically reduced. B1957+20 B1957+20 Artist's illustrations of B1957+20 "This pulsar has been through hell, yet somehow it's still able to generate high-energy particles just like its younger brethren," continued Gaensler. The key is the rapid rotation of B1957+20. The Chandra result confirms the theory that even a relatively weakly magnetized neutron star can generate intense electromagnetic forces and accelerate particles to high energies to create a pulsar wind, if it is rotating rapidly enough. Chandra's Advanced CCD Imaging Spectrometer observed B1957+20 for over 40,000 seconds on June 21, 2001.

STScI-PRC98-38 GREAT BALLS OF FIRE! HUBBLE SEES BRIGHT KNOTS EJECTED FROM BRILLIANT STAR

NASA Technical Reports Server (NTRS)

2002-01-01

Resembling an aerial fireworks explosion, this dramatic NASA Hubble Space Telescope picture of the energetic star WR124 reveals it is surrounded by hot clumps of gas being ejected into space at speeds of over 100,000 miles per hour. Also remarkable are vast arcs of glowing gas around the star, which are resolved into filamentary, chaotic substructures, yet with no overall global shell structure. Though the existence of clumps in the winds of hot stars has been deduced through spectroscopic observations of their inner winds, Hubble resolves them directly in the nebula M1-67 around WR124 as 100 billion-mile wide glowing gas blobs. Each blob is about 30 times the mass of the Earth. The massive, hot central star is known as a Wolf-Rayet star. This extremely rare and short-lived class of super-hot star (in this case 50,000 degrees Kelvin) is going through a violent, transitional phase characterized by the fierce ejection of mass. The blobs may result from the furious stellar wind that does not flow smoothly into space but has instabilities which make it clumpy. The surrounding nebula is estimated to be no older than 10,000 years, which means that it is so young it has not yet slammed into the gasses comprising the surrounding interstellar medium. As the blobs cool they will eventually dissipate into space and so don't pose any threat to neighboring stars. The star is 15,000 light-years away, located in the constellation Sagittarius. The picture was taken with Hubble's Wide Field Planetary Camera 2 in March 1997. The image is false-colored to reveal details in the nebula's structure.

2016-03-01

In Western studies, one-third of patients with Crohn's disease have stricturing or penetrating disease at presentation and one-half will progress to complicated disease in 20 years. Asian studies indicate that the Asian disease phenotype may be different. Our aim was to study the disease behaviour in Indian patients with Crohn's disease. In this hospital-based study, we analysed [Montreal classification] disease phenotype, presence of perianal disease, need for intestinal surgery, and changes in the Montreal classification over time in Crohn's disease patients from our database. In the 178 patients (median age 35, interquartile range [IQR] 21 years; 97 males) with Crohn's disease, the proportion of various features was as follows. More patients had ileo-colonic[L3: 43.8%] than ileal[L1: 27.5%] or colonic[L2: 28.7%] disease. Perianal disease was seen in 11.8% at baseline. Non-stricturing, non-fistulising disease[B1] was seen in 74.7%, 65.7%, 50%, and 44.4% at baseline, at 5, 10 and 15 years, respectively. Stricturing disease[B2] was seen in 21.4%, 21.9%, 28.9%, and 33.3%; penetrating disease[B3] in 3.9%, 11.4%, 21%, and 16.7%; and intestinal surgery was required in 10.7%, 20%, 34.2%, and 55.5%, respectively. KaplanMeier analysis showed no association between progression of disease and patient age or the location of the disease. Gender distribution and predominant ileo-colonic location of disease were similar to earlier Asian reports on Crohn's disease. Perianal disease was less frequent than reported in Western and other Asian studies. One-fourth of Indian patients had aggressive disease at diagnosis, but the tendency to progress towards aggressive disease over time was less pronounced than in Western patients.

PURPOSE. To assess the evolution of perceived ownership of a university-Aboriginal community partnership across three project stages. DESIGN. Survey administration to project partners during project formalization (1996-T1), mobilization (1999-T2), and maintenance (2004-T3). SETTING. Aboriginal community of Kahnawake, outside Montreal, Quebec, Canada. PARTICIPANTS. Partners involved in influencing decision making in the Kahnawake Schools Diabetes Prevention Project (KSDPP). MEASURE AND ANALYSIS . A measure of perceived primary ownership subjected to linear trend analysis. RESULTS. KSDPP staff were perceived as primary owner at T1 and shared ownership with Community Advisory Board (CAB) members at T2 and T3. Trend tests indicated greater perceived ownership between T1 and T3 for CAB (χ(2)(1)  =  12.3, p < .0001) and declining KSDPP staff (χ(2)(1)  =  10.5, p < .001) ownership over time. Academic partners were never perceived as primary owners. CONCLUSION. This project was community driven from the beginning. It was not dependent on an external academic change agent to activate the community and develop the community's capacity to plan and implement a solution. It still took several years for the grassroots CAB to take responsibility from KSDPP staff, thus indicating the need for sustained funding to build grassroots community capacity.

Comparison between low-level laser therapy (LLLT) and clonazepam for treating burning mouth syndrome (BMS) patients has never been documented; the aim of this study was to assess the effects of LLLT photobiomodulation versus medical therapy with clonazepam on BMS. Thirty-three patients (25 female, 8 male, mean age = 67.12) were randomly allocated to two different groups: the first one (group A, 18 patients) underwent two laser irradiation sessions weekly for 5 weeks, whereas the second one (group B, 15 patients) received topical clonazepam therapy [half a tablet (2 mg) in the mouth without swallowing for 3 min, three times a day for 21 days]. LLLT was delivered with a continuous wave 980-nm aluminum gallium arsenide (AlGaAs) diode laser and the output of 300 mW, delivering a Fluence of 10 J/cm(2), using a "spot technique," with an average power density of about 1 W/cm(2). The laser probe was held perpendicularly at a distance of about 2 mm from the mucosa. Visual analogue scale (VAS), McGill Pain Questionnaire, present pain intensity (PPI), and Oral Health Impact Profile (OHIP-49) assessed sensation of pain. Hospital Anxiety and Depression Scale and Geriatric Depression Scale assessed levels of anxiety and depression. Twelve weeks after the end of treatment, patients treated with LLLT experienced a decrease in pain sensation reported for all the parameters analyzed: VAS (P = 0.004), McGill Pain Questionnaire (P = 0.002), PPI (P = 0.002), and OHIP-49 (P = 0.010). The group treated with clonazepam had less favorable results for VAS (P = 0.33), McGill Pain Questionnaire (P = 0.005), PPI (P = 0.013), and OHIP-49 (P = 0.25). Levels of anxiety and depression did not change statistically in any groups (P > 0.05). Comparing the two groups, LLLT appeared to be superior in improving pain perception, but statistically only at 8 weeks after the end of the protocol proposed (P = 0.026). Based on this preliminary trial, LLLT is capable of reducing the symptoms of patients with BMS with a constant and long-lasting effect, experienced since the end of the first applications.

Star Cluster Buzzing With Pulsars

NASA Astrophysics Data System (ADS)

2005-01-01

A dense globular star cluster near the center of our Milky Way Galaxy holds a buzzing beehive of rapidly-spinning millisecond pulsars, according to astronomers who discovered 21 new pulsars in the cluster using the National Science Foundation's 100-meter Robert C. Byrd Green Bank Telescope (GBT) in West Virginia. The cluster, called Terzan 5, now holds the record for pulsars, with 24, including three known before the GBT observations. Pulsar Diagram Pulsar Diagram: Click on image for more detail. "We hit the jackpot when we looked at this cluster," said Scott Ransom, an astronomer at the National Radio Astronomy Observatory in Charlottesville, VA. "Not only does this cluster have a lot of pulsars -- and we still expect to find more in it -- but the pulsars in it are very interesting. They include at least 13 in binary systems, two of which are eclipsing, and the four fastest-rotating pulsars known in any globular cluster, with the fastest two rotating nearly 600 times per second, roughly as fast as a household blender," Ransom added. Ransom and his colleagues reported their findings to the American Astronomical Society's meeting in San Diego, CA, and in the online journal Science Express. The star cluster's numerous pulsars are expected to yield a bonanza of new information about not only the pulsars themselves, but also about the dense stellar environment in which they reside and probably even about nuclear physics, according to the scientists. For example, preliminary measurements indicate that two of the pulsars are more massive than some theoretical models would allow. "All these exotic pulsars will keep us busy for years to come," said Jason Hessels, a Ph.D student at McGill University in Montreal. Globular clusters are dense agglomerations of up to millions of stars, all of which formed at about the same time. Pulsars are spinning, superdense neutron stars that whirl "lighthouse beams" of radio waves or light around as they spin. A neutron star is what is left after a massive star explodes as a supernova at the end of its life. The pulsars in Terzan 5 are the product of a complex history. The stars in the cluster formed about 10 billion years ago, the astronomers say. Some of the most massive stars in the cluster exploded and left the neutron stars as their remnants after only a few million years. Normally, these neutron stars would no longer be seen as swiftly-rotating pulsars: their spin would have slowed because of the "drag" of their intense magnetic fields until the "lighthouse" effect is no longer observable. The Green Bank Telescope The Robert C. Byrd Green Bank Telescope CREDIT: NRAO/AUI/NSF (Click on image for GBT gallery) However, the dense concentration of stars in the cluster gave new life to the pulsars. In the core of a globular cluster, as many as a million stars may be packed into a volume that would fit easily between the Sun and our nearest neighbor star. In such close quarters, stars can pass near enough to form new binary pairs, split apart such pairs, and binary systems even can trade partners, like an elaborate cosmic square dance. When a neutron star pairs up with a "normal" companion star, its strong gravitational pull can draw material off the companion onto the neutron star. This also transfers some of the companion's spin, or angular momentum, to the neutron star, thereby "recycling" the neutron star into a rapidly-rotating millisecond pulsar. In Terzan 5, all the pulsars discovered are rotating rapidly as a result of this process. Astronomers previously had discovered three pulsars in Terzan 5, some 28,000 light-years distant in the constellation Sagittarius, but suspected there were more. On July 17, 2004, Ransom and his colleagues used the GBT, and, in a 6-hour observation, found 14 new pulsars, the most ever found in a single observation. "This was possible because of the great sensitivity of the GBT and the new capabilities of our backend processor," said Ingrid Stairs, a professor at the University of British Columbia in Vancouver. The processor, named, appropriately, the Pulsar Spigot, was built in a collaboration between the NRAO and the California Institute of Technology. The processor, which generates almost 100 GigaBytes of data per hour, allowed the astronomers to gather and analyze radio waves over a wide range of frequencies (1650-2250 MegaHertz), adding to the sensitivity of their system. Eight more observations between July and November of 2004 discovered seven additional pulsars in Terzan 5. In addition, the astronomers' data show evidence for several more pulsars that still need to be confirmed. Future studies of the pulsars in Terzan 5 will help scientists understand the nature of the cluster and the complex interactions of the stars at its dense core. Also, several of the pulsars offer a rich yield of new scientific information. The scientists suspect that one pulsar, which shows strange eclipses of its radio emission, has recently traded its original binary companion for another, and two others have white-dwarf companions that they believe may have been produced by the collision of a neutron star and a red-giant star. Subtle effects seen in these two systems can be explained by Einstein's general relativistic theory of gravity, and indicate that the neutron stars are more massive than some theories allow. The material in a neutron star is as dense as that in an atomic nucleus, so that fact has implications for nuclear physics as well as astrophysics. "Finding all these pulsars has been extremely exciting, but the excitement really has just begun," Ransom said. "Now we can start to use them as a rich and valuable cosmic laboratory," he added. In addition to Ransom, Hessels and Stairs, the research team included Paulo Freire of Arecibo Observatory in Puerto Rico, Fernando Camilo of Columbia University, Victoria Kaspi of McGill University, and David Kaplan of the Massachusetts Institute of Technology. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc. The pulsar research also was supported by the Canada Foundation for Innovation, Science and Engineering Research Canada, the Quebec Foundation for Research on Nature and Technology, the Canadian Institute for Advanced Research, Canada Research Chairs Program, and the National Science Foundation.

Review of plants to mitigate particulate matter, ozone as well as nitrogen dioxide air pollutants and applicable recommendations for green roofs in Montreal, Quebec.

PubMed

Gourdji, Shannon

2018-05-28

In urbanized regions with expansive impervious surfaces and often low vegetation cover, air pollution due to motor vehicles and other combustion sources, is a problem. The poor air quality days in Montreal, Quebec are mainly due to fine particulate matter and ozone. Businesses using wood ovens are a source of particulates. Careful vegetation selection and increased green roof usage can improve air quality. This paper reviews different green roofs and the capability of plants in particulate matter (PM), ozone (O 3 ) as well as nitrogen dioxide (NO 2 ) level reductions. Both the recommended green roof category and plants to reduce these pollutants in Montreal's zone 5 hardiness region are provided. Green roofs with larger vegetation including shrubs and trees, or intensive green roofs, remove air pollutants to a greater extent and are advisable to implement on existing, retrofitted or new buildings. PM is most effectively captured by pines. The small Pinus strobus 'Nana', Pinus mugho var. pumilio, Pinus mugho 'Slowmound' and Pinus pumila 'Dwarf Blue' are good candidates for intensive green roofs. Drought tolerant, deciduous broadleaved trees with low biogenic volatile organic compound emissions including Japanese Maple or Acer palmatum 'Shaina' and 'Mikawa-Yatsubusa' are options to reduce O 3 levels. Magnolias are tolerant to NO 2 and it is important in their metabolic pathways. The small cold-tolerant Magnolia 'Genie' is a good option to remove NO 2 in urban settings and to indirectly reduce O 3 formation. Given the emissions by Montreal businesses' wood ovens, calculations performed based on their respective complex roof areas obtained via Google Earth Pro indicates 88% Pinus mugho var. pumilio roof coverage can annually remove 92.37 kg of PM 10 of which 35.10 kg is PM 2.5 . The removal rates are 4.00 g/m 2 and 1.52 g/m 2 for PM 10 and PM 2.5 , respectively. This paper provides insight to addressing air pollution through urban rooftop greening.

Subtropical air masses over eastern Canada: Their links to extreme precipitation

Gyakum, John; Wood, Alice; Milrad, Shawn; Atallah, Eyad

2017-04-01

We investigate extremely warm, moist air masses with an analysis of 850-hPa equivalent potential temperature (θe) extremes at Montreal, Quebec. The utility of using this metric is that it represents the thermodynamic property of air that ascends during a precipitation event. We produce an analysis of the 40 most extreme cases of positive θe, 10 for each season, based upon standardized anomalies from the 33-year climatology. The analysis shows the cases to be characterized by air masses with distinct subtropical traits for all seasons: reduced static stability, anomalously high precipitable water, and anomalously elevated dynamic tropopause heights. Persistent, slow moving upper- and lower-level features were essential in the build up of high- θe air encompassing much of eastern Canada. The trajectory analysis also showed anticyclonic curvature to all paths in all seasons, implying that the subtropical anticyclone is crucial in the transport of high- θe air. These atmospheric rivers during the winter are characterized by trajectories from the subtropical North Atlantic, and over the Gulf Stream current, northward into Montreal. In contrast, the summer anticyclonic trajectories are primarily continental, traveling from Texas north-northeastward into the Great Lakes, and then eastward into Montreal. The role of the air mass in modulating the strength of a precipitation event is addressed with an analysis of the expression, P = RD, where P is the total precipitation, and R is the precipitation rate, averaged through the duration, D, of the event. Though appearing simple, this expression includes R, (assumed to be same as condensation, with an efficiency of 1), which may be expressed as the product of vertical motion and the change of saturation mixing ratio following a moist adiabat, through the troposphere. This expression for R includes the essential ingredients of lift, air mass temperature, and static stability (implicit in vertical motion). We use this expression for precipitation rate to study the extreme precipitation events in Montreal that are associated with these same cases of extreme warm, moist air masses, and their physical impacts on the precipitation rate. Implications of this air mass modulation on precipitation rate are discussed in the context of longer-term global climate change.

To examine the association between the local food environment and the severity of food insecurity among new families using community food security interventions in Montreal. In this cross-sectional study, we analyzed baseline data from 785 adults aged 18-65 years enrolled in the evaluation of the effects of organizations delivering community food security interventions in Montreal. The dependent variable was household food insecurity, while the independent variable was the local food environment, assessed through: location of the most frequently used grocery store, distance between the participant's residence and the community organization used, mode of transportation, walking time to the most frequently used grocery store, satisfaction with the acceptability and affordability of food available at the most frequently used grocery store, and self-reported difficulties in accessing food. We used polytomous logistic regression to estimate the association between household food insecurity and the local food environment. In all the models, we coded food security status in three categories: food security, moderate food insecurity and severe food insecurity. The last group was used as a reference group. Our data suggest that compared to households with severe food insecurity, those with moderate food insecurity (OR = 0.43, 95% CI: 0.28-0.62) and those with food security (OR = 0.13, 95% CI: 0.06-0.26) were less likely to report difficulties in accessing food due to food affordability. Food-secure households also had lower odds of reporting difficulties in accessing food due to transportation constraints (OR = 0.18, 95% CI: 0.06-0.55) compared with severe food-insecure households. Living a distance of between 1 and 2 km from the organization used was significantly correlated with moderate food insecurity (OR = 1.80, 95% CI: 1.12-2.88). The local food environment is associated with severity of household food insecurity among new families using community food security interventions in Montreal. Future studies should study the relationship between the local food environment and food insecurity across all dimensions of food access.

Uptake of HPV vaccination among university students remains low despite risky sexual practices and increased prevalence of high-risk HPV genotypes. The study objective was to determine the level of knowledge related to HPV and cervical cancer among university students and to subsequently develop a targeted education and vaccination campaign to increase uptake. Phase I was a pilot project in which participants were recruited as part of Cervical Cancer Awareness Week 2015 at two universities, one site immediately offering vaccination and the other not. A self-administered questionnaire was used to collect demographic information from participants and evaluate their baseline knowledge related to HPV and the risks of cervical cancer, in addition to determining barriers to vaccination and future willingness to be vaccinated. Data was compiled and analyzed using descriptive statistics of means and percentages. In phase II, which followed 1 year after, a targeted education and vaccination campaign was designed based on lessons learned from phase I, and vaccination uptake was reevaluated after 1 year. In phase I, 56 participants responded to a questionnaire related to HPV knowledge and cervical cancer. Among these, 29 students were vaccinated in a 2-day resident-run clinic. Overall, 63% felt they were not at risk of cervical cancer, though 88% knew HPV was the cause of cervical cancer. The three barriers identified to previous vaccination were lack of access to a doctor or a nurse (25%), financial reasons (25%), and low self-perceived risk (7%). There was a 50% three-dose completion rate in phase I. Based on this information, the education campaign in phase II was expanded in the subsequent year through social media, email communication, information booths, and individual solicitation. A total of 151 students were approached for individual solicitation and education. Among these, 64 students were vaccinated on site, including five men. Most importantly, there were 18 walk-ins resulting directly from the education initiatives and person-to-person solicitation. Subsequently, in 2016, 502 students were vaccinated at the McGill student health clinic and 455 at Concordia University. HPV vaccination rates in university students are readily increased through educational campaigns, of which person-to-person solicitation proved to be the most fruitful in this study. Identifying barriers to vaccination can guide future initiatives to maximize impact. Crown Copyright © 2018. Published by Elsevier Inc. All rights reserved.

The purpose of this study was to explore how Turkish nonmalignant pain patients described their pain and how the language of pain used by Turkish patients compares to the language found in common pain assessment tools. Pain is influenced by a combination of ethnic, cultural, psychological, and social variants. In the Turkish language, six words are central to pain-like experiences: ağri (pain), aci (suffering), sizi (aching), sanci (colic), istirap (agony), and dert (torture). We assessed discriminant characteristics of the Turkish translation of the McGill Pain Questionnaire (MPQ). Chronic clinical nonmalignant pain patients (n = 319, 35.7% males, 64.3% females) were questioned with the Turkish translation of the MPQ. Pain symptoms were categorized as headache (33.5%), musculoskeletal pain (33.2%), visceral pain (18.8%), and low back pain (14.5%). The visceral pain group had the highest mean value in the evaluative subscale (2.6 +/- 1.9). Descriptions used for sensory subscale included throbbing, sharp, aching, and tingling, while affective subscale words included tiring, suffocating, sickening, cruel, and wretched. In all pain groups, frequently chosen words for the miscellaneous subscale were nagging and penetrating. Pain descriptors were identified for each type of pain. This is, to our knowledge, the first assessment of the Turkish translation of the MPQ in nonmalignant pain patients.

Patient-reported outcome (PRO) data are beneficial to a range of stakeholders including patients, clinicians, researchers, national funding and regulatory agencies, health system administrators, and policymakers. Because stakeholders represent diverse groups and needs, it is challenging to reach consensus on how to advance PRO development and harmonize data across settings to enable use for multiple secondary purposes. Collaborative national networks can facilitate the sharing of expertise, resources, and necessary infrastructure; create development, use, and reporting standards; optimize formats to efficiently store and transfer data; and disseminate tools and information for widespread uptake. In the United States, the National Institutes of Health's Patient-Reported Outcomes Measurement Information System offers an example of how collaborators can work across distances to form essential partnerships, create a common vision, and leverage technology to accelerate the development and testing of universal PROs that are broadly applicable across health conditions and settings.

2006-07-01

A 3-year-old African hedgehog (Atelerix albiventris) was presented to the Exotic Animal Clinic of the University of Montreal for evaluation of a mass growing on the right thoracic wall. The diagnostic workup, which included helical computed tomography, confirmed the presence of a large mass, originating from the right 7th rib, infiltrating the thoracic wall and cavity. The animal was euthanized due to the poor prognosis. At necropsy, a well-demarcated mass penetrated the thoracic wall and incorporated the 6th to 8th ribs. Cut sections of the tumor were white, glistening, firm, and gritty. Microscopically, it was composed of polyhedral to elongated cells with interspersed trabeculae of osteoid and large areas of coagulative necrosis. On the basis of histopathologic findings, a diagnosis of osteoblastic osteosarcoma was made. To the authors' knowledge, this is the first report of an osteoblastic osteosarcoma on the thoracic wall of an African hedgehog, as well as the first report of the use of helical computed tomography in that species.

2015-01-01

Davanloo's Intensive Short-term Dynamic Psychotherapy has been the subject of various reviews. Davanloo has published extensively on his early work, but there have been no publications on his most recent work-most notably his Montreal Closed-circuit training program. This program focuses on his most recent discoveries and techniques and is a unique, videotaped supervisory program. It focuses on self-assessment and peer-assessment. It is also a unique format in which to review Davanloo's theoretical conceptions of resistance and the transference component of the resistance. This paper will review the early work of Davanloo as well as his most recent research findings. A case from the Montreal Closed-circuit training program will be reviewed in detail to highlight these findings.

Accelerating Translational Research through Open Science: The Neuro Experiment.

Gold, E Richard

2016-12-01

Translational research is often afflicted by a fundamental problem: a limited understanding of disease mechanisms prevents effective targeting of new treatments. Seeking to accelerate research advances and reimagine its role in the community, the Montreal Neurological Institute (Neuro) announced in the spring of 2016 that it is launching a five-year experiment during which it will adopt Open Science-open data, open materials, and no patenting-across the institution. The experiment seeks to examine two hypotheses. The first is whether the Neuro's Open Science initiative will attract new private partners. The second hypothesis is that the Neuro's institution-based approach will draw companies to the Montreal region, where the Neuro is based, leading to the creation of a local knowledge hub. This article explores why these hypotheses are likely to be true and describes the Neuro's approach to exploring them.

Modeling climate effects on hip fracture rate by the multivariate GARCH model in Montreal region, Canada.

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.

The absence of ongoing surveillance for childhood asthma in Montreal, Quebec, prompted the present investigation to assess the validity and practicality of administrative databases as a foundation for surveillance. To explore the consistency between cases of asthma identified through physician billings compared with hospital discharge summaries. Rates of service use for asthma in 1998 among Montreal children aged one, four and eight years were estimated. Correspondence between the two databases (physician billing claims versus medical billing claims) were explored during three different time periods: the first day of hospitalization, during the entire hospital stay, and during the hospital stay plus a one-day margin before admission and after discharge ('hospital stay +/- 1 day'). During 1998, 7.6% of Montreal children consulted a physician for asthma at least once and 0.6% were hospitalized with a principal diagnosis of asthma. There were no contemporaneous physician billings for asthma 'in hospital' during hospital stay +/- 1 day for 22% of hospitalizations in which asthma was the primary diagnosis recorded at discharge. Conversely, among children with a physician billing for asthma 'in hospital', 66% were found to have a contemporaneous in-hospital record of a stay for 'asthma'. Both databases of hospital and medical billing claims are useful for estimating rates of hospitalization for asthma in children. The potential for diagnostic imprecision is of concern, especially if capturing the exact number of uses is more important than establishing patterns of use.

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. © 2012 Wiley Periodicals, Inc.

The aim of the present research was to study the ghrelin level, executive function and their possible association in patients with type 2 diabetes mellitus. A total of 370 people were recruited between March 2015 and March 2016 in this study. Among them, 212 participants were patients with type 2 diabetes mellitus and 158 participants were included as the control group. Their blood sample was analyzed for the level of ghrelin and other clinical indexes. Cognitive function was measured by the Montreal Cognitive Assessment, and executive function was evaluated by the Wisconsin Card Sorting Test. In the type 2 diabetes mellitus group, age, years of education, duration of diabetes, fasting blood glucose, glycated hemoglobin, hypertension and waist-to-hip ratio were correlated with total Montreal Cognitive Assessment scores. No association was found between ghrelin level and total Montreal Cognitive Assessment score in patients with type 2 diabetes mellitus. However, ghrelin was found to be a significant predictor for executive function impairment measured by the Wisconsin Card Sorting Test in patients with type 2 diabetes mellitus. The level of serum ghrelin might be a biomarker of executive function and become a strong predictor of executive function impairment in patients with type 2 diabetes mellitus. Ghrelin might have a potential protective effect against cognitive function impairment in type 2 diabetes patients. © 2016 The Authors.

Objectives To analyze experience at the McGill University Health Centre with cardiopulmonary bypass (CPB) in trauma, complemented by a review of the literature to define its role globally and outline indications for its expanded use in trauma management. Data sources All available published English-language articles from peer reviewed journals, located using the MEDLINE database. Chapters from relevant, current textbooks were also utilized. Study selection Nine relevant case reports, original articles or reviews pertaining to the use of CPB in trauma. Data extraction Original data as well as authors’ opinions pertinent to the application of CPB to trauma were extracted, incorporated and appropriately referenced in our review. Data synthesis Overall mortality in the selected series of CPB used in the trauma setting was 44.4%. Four of 5 survivors had CPB instituted early (first procedure in operative management) whereas 3 of 4 deaths involved late institution of CPB. Conclusions Although CPB has traditionally been used in the setting of cardiac trauma alone, a better understanding of its potential benefit in noncardiac injuries will likely make for improved outcomes in the increasingly diverse number of severely injured patients seen in trauma centres today. Further studies by other trauma centres will allow for standardized indications for the use of CPB in trauma. PMID:11939667

Describing medical student curiosity across a four year curriculum: An exploratory study.

Intellectual curiosity can be defined as a desire for knowledge that leads to exploratory behavior and consists of an inherent and stable trait (i.e. trait curiosity) and a variable context-dependent state (i.e. state curiosity). Although intellectual curiosity has been considered an important aspect of medical education and practice, its relationship to medical education has not been empirically investigated. The purpose of this exploratory study was to describe medical students' intellectual curiosity across a four-year undergraduate program. We employed a cross-sectional design in which medical students, across a four-year undergraduate program at McGill University, completed the Melbourne Curiosity Inventory as a measure of their state and trait intellectual curiosity. A Mixed Models ANOVA was used to compare students across year of training. Four hundred and two out of 751 students completed the inventory (53.5%). Trait curiosity was significantly higher than state curiosity (M = 64.5, SD = 8.5 versus M = 58.5, SD = 11.6) overall, and within each year of training. This study is the first to describe state and trait intellectual curiosity in undergraduate medical education. Findings suggest that medical students' state curiosity may not be optimally supported and highlight avenues for further research.

To measure the effect of seeing a photograph of the pelvic findings at laparoscopy. Two university teaching hospitals. A randomised-controlled trial. Two hundred thirty-three women undergoing diagnostic laparoscopy for the investigation of chronic pelvic pain. At operation a Polaroid print was taken of the pelvis. If this was of satisfactory quality, the patient was randomly allocated to either see, or not see, the print during the postoperative consultation. Pain severity and pain belief scores at 3 and 6 months. By intention to treat. Postoperative consultations with photographs did not improve immediate understanding and satisfaction with the consultation. In addition, compared to controls, both patients and doctors did not perceive particular benefit for communication from the photograph. There was a consistent trend to more pain in the photographic reinforcement group and more negative pain beliefs. At 3 months, the average within person differences showed some benefit in visual analogue pain scores, McGill affect scores, 'permanence' and 'self-blame' scores. These benefits were not statistically significant. At 6 months, there was a consistent pattern of benefit from pain severity and pain beliefs, again these benefits were not statistically significant. No clear benefits result from showing patients photographs of their pelvis.

This article is extracted from a doctoral thesis that was supported by a research grant from the International Development Research Centre of Canada (IDRC)'s Ecosystem Approaches to Human Health Training Award, the Royal Anthropological Institute of Great Britain and Northern Ireland's Emslie Horniman Scholarship Fund and McGill University, Faculty of Graduate Studies and Research's Humanities and Social Sciences Research Award. This study used a broad theoretical framework encompassing an ecosystem approach to HIV-1/AIDS that partly investigated the nexus between local knowledge of tuberculosis (TB) and HIV-1/AIDS. According to the Turkana of Lodwar township, Kenya, HIV-1/AIDS and TB are largely contagious and are attributed to impersonal and natural causes. In addition, in line with biomedical knowledge, the Turkana's local knowledge emphasises a conceptual link between TB and HIV-1/AIDS. The study also demonstrates that factors of the ecosystem such as kaada, poverty, widow inheritance, migration and other socio-cultural practices play an influential role in the vulnerability of the Turkana to the contraction and transmission of both TB and HIV-1/AIDS. The article posits an integrated approach to the prevention of TB and HIV-1 and to the management of AIDS and TB.
