Objectives The aim was to analyse a prospective, consecutive series of awake carotid endarterectomy (CEA) patients undergoing, when possible, pre- and postoperative diffusion-weighted magnetic resonance imaging brain scans (DWI). Methods All CEA patients from June 23, 2006, to January 13, 2012, were prospectively entered in the study. CEA was performed under regional cervical block. Only patients demonstrating shunt dependence were shunted. Before August 7, 2008, all longitudinal endarterectomy had been performed with a vein patch. From that date all CEA were eversions without a patch, except shunted patients who were vein patched. DWI was performed 2 days before and 5 days after (3 Tesla). Scans were reported by MRI-trained radiologists. Logistic regression analysis (LRA) identified predictive variables for MRI changes using backward stepwise elimination of variables with p >.05. Results There was a total of 295 consecutive CEA. There were no deaths but four clinical strokes (1.4 %); 89 excluded from DWI leaving 206; of these 27 (13%) developed new DWI lesions including four of 57 (7%) in the asymptomatic group and 23 of 149 (15%) symptomatic patients. Nineteen of the 206 (9.2%) were shunted. LRA showed that shunt dependence was highly associated with new DWI lesions: odds ratio (OR) 6.43; 95% confidence interval (CI) 2.3-17.9; p <.001. Both the vein patched, non-shunted group (OR.25; CI 0.09-0.72; p =.010) and the eversion (all non-shunted and all non-patched) group (OR 0.05; CI 0.01-0.22; p <.001) were associated with a low risk of new lesions, with the eversion group a lower risk than the patched group. Conclusions One in every eight CEA patients developed new DWI lesions (rate doubled in symptomatic patients). Shunt dependence in conscious CEA patients is highly associated with the development of new DWI lesions compared with non-shunted patients. For non-shunted patients the new lesion risk is low, and in those patients the risk in the eversion group is lower than in the patched group. © 2015 European Society for Vascular Surgery.

Sri Lanka has an ageing population with an impending epidemic of stroke at hand. Stroke is the leading cause of adult disability in Sri Lanka. Sri Lanka has seen many recent advances in stroke services in the recent past providing a benchmark example for the countries in the Asia Pacific region, modeling the best care for stroke patients across the region with limited facilities they have. Three postgraduate trainees in neurology and medicine from Sri Lanka will spend a year at Western Health/ University of Melbourne, Melbourne, Australia for a period of 12 months for training in neurorehabilitation for stroke. It is timely for neurology trainees and trainees in internal medicine in Sri Lanka to be interested in neurorehabilitation. We sincerely hope the Board of study of Neurology, Post Graduate Institute of Medicine, Colombo, Sri Lanka will take the necessary steps to establish neurorehabilitation as an emerging sub-specialty for neurology trainees in Sri Lanka now. © 2011 The Authors.

(TORONTO, Canada - Dec. 14, 2016) - Scientists from the McEwen Centre for Regenerative Medicine, University Health Network, have developed the first functional pacemaker cells from human stem cells, paving the way for alternate, biological pacemaker therapy. Their findings, "Sinoatrial node cardiomyocytes derived from human pluripotent cells function as a biological pacemaker," published online in Nature Biotechnology on Dec. 12, detail how human pluripotent stem cells can be coaxed in 21 days to develop into pacemaker cells, which regulate heart beats with electrical impulses. These human pacemaker cells were tested in rat hearts and were shown to function as a biological pacemaker, by activating the electrical impulses that trigger the contraction of the heart. Pluripotent stem cells have the potential to differentiate into more than 200 different cell types that make up every tissue and organ in the body. Sinoatrial node pacemaker cells are the heart's primary pacemaker, controlling the heartbeat throughout life. Defects in the pacemaker can lead to heart rhythm disorders that are commonly treated by implantation of electronic pacemaker devices. Learning how to generate pacemaker cells could help in understanding disorders in pacemaker cells, and provide a cell source for developing a biological pacemaker. Biological pacemakers represent a promising alternative to electronic pacemakers, overcoming such drawbacks as a lack of hormonal responsiveness and the inability to adapt to changes in heart size in pediatric patients. The researchers used a developmental-biology approach to establish a specific protocol for generating the pacemaker cells. "What we are doing is human biology in a petri dish," says Dr. Gordon Keller, Director of the McEwen Centre, the senior author, and a trailblazer in generating a wide variety of specialized cells from human stem cells. "We are replicating nature's way of making the pacemaker cell." Based on previous findings in animal models, the researchers at the McEwen Centre tested and mapped out the specific developmental pathway of how human pluripotent stem cells become pacemaker cells. This was achieved by testing different signaling molecules at different times throughout the 21 days to guide the cells towards their goal. "It's tricky," says Dr. Stephanie Protze, a post-doctoral fellow in the laboratory of Dr. Keller and the first author in the Nature paper. "You have to determine the right signaling molecules, at the right concentration, at the right time to stimulate the stem cells." Adds Dr. Keller, who is also a Professor in the Department of Medical Biophysics at the University of Toronto: "We understand the importance of precision in developmental biology in setting out the process by which organisms grow and develop. We use that same precision in the petri dish because we are replicating these same processes." Once the team established which signaling pathways are activated at different stages to generate the pacemaker cells, they demonstrated that the new pacemaker cells could initiate and regulate the heartbeat in rats. The researchers noted that human clinical trials to test such biological pacemakers are from five to 10 years away, and that the next step is to launch safety and reliability pre-clinical trials on the pacemaker cells. Meanwhile, researchers can use their new technology to make pacemaker cells from patients suffering from pacemaker dysfunction. They can then use these patient-specific cells to study the "disease in a (petri) dish" and to identify new drugs that will improve their pacemaker function. Long term, the team hopes to develop a biological pacemaker to transplant into patients who need an electronic one. More than 10,000 electric pacemakers are implanted annually in Canada, with more than 120,000 patients living with them. They can last anywhere from five to 10 years or more -- on the average about seven years. If successful, the biological pacemaker holds the promise of a lifelong cure. This research is part of an international collaboration with Dr. Lior Gepstien from Technion Insitute of Technolgy and Dr. Peter Backx, Senior Scientist at the Peter Munk Cardiac Centre and Toronto General Research Institute, UHN. The partnership of UHN, Technion, the McEwen Centre for Regenerative Medicine and the Peter Munk Cardiac Centre, under the International Centre for Cardiovascular Innovation, is the largest scientific collaboration of its kind. Philanthropic donations to the Toronto General & Western Hospital Foundation and the Canadian Institutes of Health Research (CIHR) funded this research. About the McEwen Centre for Regenerative Medicine The McEwen Centre for Regenerative Medicine was founded with generous donations from Rob and Cheryl McEwen. The centre includes 16 scientists at five Toronto hospitals, as well as the University of Toronto. Currently, these scientists are working to accelerate the development of more effective treatments for conditions such as heart disease, diabetes, liver disease, arthritis and diseases of the blood like leukemia.

PURPOSE OF REVIEW: Influenza pandemics occur intermittently and represent an existential global infectious diseases threat. The purpose of this review is to describe clinical and research preparedness for future pandemics. RECENT FINDINGS: Pandemic influenza typically results in large numbers of individuals with life-threatening pneumonia requiring treatment in ICUs. Clinical preparedness of ICUs relates to planning to provide increased 'surge' capacity to meet increased demand and requires consideration of staffing, equipment and consumables, bed-space availability and management systems. Research preparedness is also necessary, as timely clinical research has the potential to change the trajectory of a pandemic. The clinical research response during the 2009 H1N1 influenza pandemic was suboptimal. SUMMARY: Better planning is necessary to optimize both clinical and research responses to future pandemics. © 2013 Wolters Kluwer Health Lippincott Williams & Wilkins.

Background: Gestational diabetes rates have increased dramatically in the past two decades and this pattern of increase appears to relate primarily to the obesity epidemic, older maternal age and migration from world areas of high GDM risk. Women from disadvantaged and migrant backgrounds are most at risk of developing and of mismanaging this condition. The aim of the study was to explore the factors that facilitated or inhibited gestational diabetes self-management among women in a socially deprived area.Methods: Fifteen pregnant women, with a diagnosis of gestational diabetes, were purposively recruited for this study. Qualitative semi structured interviews and 1 focus group were conducted when participants were approximately 28-38 weeks gestation. The study's theoretical framework was based on interpretative phenomenology and data was analysed using a thematic analysis approach.Results: Women in this study identified a number of factors that complicated their task of GDM self-management. Barriers included: (1) time pressures; (2) physical constraints; (3) social constraints; (4) limited comprehension of requirements, and (5) insulin as an easier option. Factors facilitating GDM self-management included: thinking about the baby and psychological support from partners and families.Conclusion: Women from low socio economic and migrant backgrounds often struggle to comprehend GDM self-management requirements. To improve adherence to management plans, these women require educational and supportive services that are culturally appropriate and aimed at a low level of literacy. © 2012 Carolan et al.; licensee BioMed Central Ltd.

Aim To review the preliminary results of the ligation of the intersphincteric fistula tract (LIFT) technique in treating complex anal fistulas at our hospital. Method Between March and November 2010, patients with cryptoglandular anal fistulas were recruited prospectively from the colorectal clinic and treated using the LIFT procedure. A database was set up to collect information on demographics, past surgical treatments, fistula characteristics, MRI scan results, operative data and follow-up findings. The primary end-point measured was cure of the disease. The secondary end-point was the degree of postoperative continence. Preoperative and postoperative incontinence rates were recorded using Wexner's Incontinence Scale. Results Twenty-five patients (eight women and 17 men; median age, 40years) underwent the LIFT procedure. Ten patients had recurrent fistulas and previous fistula surgery. The median operating time was 39min. No intraoperative complications were documented. The median follow-up duration was 22 (3-43)weeks. Primary healing was observed in 17 (68.0%) patients and the median healing time was 6weeks; one wound remained incompletely healed. Seven patients (28.0%) had disease recurrence presenting between 7 and 20weeks postoperatively. No patients reported any incontinence postoperatively. Conclusion The LIFT procedure has favourable healing rates with little or no risk of incontinence. This operation is safe and easy to learn. The early results from this pilot study show promise and affirm some of the findings of other researchers. These results will suggest opportunities to conduct further controlled studies comparing the LIFT procedure with standard therapies. © 2011 The Association of Coloproctology of Great Britain and Ireland.

Aims: To determine the prevalence and clinical significance of carotid sinus syndrome (CSS) and vasovagal syncope (VVS), the two common types of Neurally Mediated Syncope (NMS), in a cohort of older patients with unexplained falls. Methods: Patients presenting with unexplained and accidental falls were identified from 200 consecutive admissions of falls in patients aged 65 years and older admitted to the Rapid Assessment Medical Unit (RAMU) in a teaching hospital. A sample of unexplained and accidental fallers underwent carotid sinus massage (CSM) and tilt table testing (TTT) as per a standardised protocol. Baseline characteristics, clinical variables and the prevalence of NMS were compared between the two groups. Results: Falls were unexplained in 26% of patients. The prevalence of NMS was 24% (5/21) among patients with unexplained falls who underwent assessment for NMS, whereas it was nil (0/17) in patients with accidental falls (P = 0.050). The prevalence of previous falls was significantly higher in patients with unexplained falls (P = 0.0025), but all other baseline characteristics were similar between the two groups. Conclusion: Falls are unexplained in a significant number of older patients presenting to acute hospitals. The assessment of unexplained fallers for NMS is clinically important as this may be aetiologically related in nearly a quarter of these patients. © 2011 European Federation of Internal Medicine.

Australian Prescriber | Year: 2012

A judicious approach in considering opioid therapy and choosing an appropriate opioid is needed. After an initial opioid trial, therapy should only be continued when there is reasonable evidence that it is effective and safe. The evidence for harm associated with long-term opioid prescribing is mounting while there is little evidence to support long-term efficacy. In many cases, reducing and eventually stopping opioid therapy may be the best course of action. Commitment by both the prescriber and the patient to a treatment plan which includes regular reviews is essential if opioid therapy is prolonged.
