Virtual doctors to help keep ER open in Hay River, N.W.T., until next week
New 'Limited' physician coverage at health centre until next Thursday, says local health authority Remote doctors will help provide care at the health centre in Hay River, N.W.T., until late next week to keep the emergency department open amid a shortage of on-site physicians, says the Hay River Health and Social Services Authority. In an update posted to Facebook Thursday afternoon, the authority said it would keep the emergency department open from July 17 to 24, with "limited" physician coverage and support from nurses and virtual doctors. The authority described virtual doctors in its release as licensed health-care professionals who provide remote care and can do things like carry out assessments and give prescriptions. "They work closely with on-site staff to ensure continuity of care," the authority said. "Residents are asked to be mindful that wait times may vary depending on physician availability and patient volumes." People are still asked to call 911 if they have an emergency. This is not the first time the authority is relying on virtual doctors. In April, it said it would go without an on-site doctor at the health centre for nearly a week. At the time, it said patients needing a doctor would be connected to one virtually or they would be medevaced to Yellowknife or Edmonton if needed.

4 hospitalized after airborne chemical release in Burnaby's Big Bend neighbourhood
Four people were taken to hospital and dozens more were temporarily evacuated after a chemical gas release in Burnaby's Big Bend neighbourhood Thursday night. In a statement Friday, the Burnaby Fire Department said crews responded to reports of a chemical odour in the 8000-block of Wiggins Street just before 11 p.m. Using portable air monitors, firefighters say they detected the presence of bromine gas and traced it to a building in the neighbourhood. The fire department says four workers at an adjacent business reported symptoms of inhalation exposure, including nose, throat and lung irritation. They were treated on site with oxygen therapy before being transported to hospital. B.C. Emergency Health Services (BCEHS) confirmed four ambulances, an advanced care paramedic team and a supervisor were dispatched to the scene. All four patients were taken to hospital in stable condition, spokesperson Brian Twaites said in a statement. As a precaution, fire crews evacuated more than 80 people from nearby buildings while monitoring the chemical plume and ventilating the affected structures. Roads in the area were closed and safety zones were established until it was deemed safe for people to return. Officials say there is no ongoing risk of exposure or further chemical release. Bromine is a naturally occurring element that is liquid at room temperature. Exposure to bromine can cause coughing, difficulty breathing and irritation of the eyes and respiratory system. The fire department says WorkSafeBC attended the scene and has launched an investigation into the incident.

Marijuana may make sleep worse, especially for regular users, study finds
A man holds a joint while smoking marijuana to celebrate the legalization of recreational cannabis, in Vancouver on Oct. 17, 2018. (Darryl Dyck / THE CANADIAN PRESS) It's a common assumption among marijuana users: Using weed will help you fall asleep and stay asleep. Scientists, however, aren't so sure that's true. 'This is an understudied but important area, as many people are increasingly turning to cannabis products as sleep aids,' said sleep specialist Wendy Troxel, a senior behavioral scientist at RAND Corporation, who was not involved in the study. 'But we really lack solid evidence demonstrating whether cannabis helps or hurts sleep,' Troxel added. Use of weed may actually harm sleep, a new study has found. The research, published Monday in a BMJ journal, revealed adults who use weed 20 or more days during the last month were 64% more likely to sleep less than six hours a night and 76% more likely to sleep longer than nine hours a night. Optimal sleep for adults is defined by the US Centers for Disease Control and Prevention as seven to eight hours a night. Moderate consumption -- using weed less than 20 days during the past month -- didn't create short sleep problems, but people were 47% more likely to snooze nine or more hours a night, the study also found. Why is short and long sleep a problem? 'Large population-based studies show that both short sleep and long sleep are associated with an increased risk of heart attacks and strokes, as well as the long-term progression of things like atherosclerosis, diabetes, coronary artery disease and any of the major cardiovascular diseases,' said lead study author Calvin Diep, who is resident in the department of anesthesiology and pain medicine at the University of Toronto. 'It seems with sleep there's kind of this 'Goldilocks phenomenon' where there's an amount that 'just right,'' Diep said. One in three Americans don't get enough sleep, according to the CDC. In addition, 50 million to 70 million Americans struggle with sleep disorders such as sleep apnea, insomnia and restless leg syndrome, which can ruin a good night's shut-eye. The CDC calls that a 'public health problem,' because disrupted sleep is associated with a higher risk of conditions including high blood pressure, weakened immune performance, weight gain, a lack of libido, mood swings, paranoia, depression, and a higher risk of diabetes, stroke, cardiovascular disease, dementia and some cancers. NO CLEAR EVIDENCE EITHER WAY The study analyzed use of marijuana for sleep among 21,729 adults between the ages of 20 and 59. The data was gathered by the National Health and Nutrition Examination Survey, and is considered representative of over 146 million Americans. In addition to issues with short and long sleep, people in the study who used weed within the last 30 days were also more likely to say they have trouble falling asleep or staying asleep, and were more likely to say they have discussed sleep problems with a health care provider, Diep said. 'The problem with our study is that we can't really say that it's causal, meaning we can't know for sure whether this was simply individuals who were having difficulty sleeping, and that's why they use the cannabis or the cannabis caused it,' he added. Prior studies have also found a connection between the two components of marijuana, CBD and THC, and poor sleep. CBD, or cannabidiol, is a key component of medical marijuana, while THC, or tetrahydrocannabinol, is the main psychoactive compound in cannabis that produces the high sensation. A 2018 randomized, double-blind, placebo-controlled study -- the gold standard -- found no benefit from CBD on sleep in healthy volunteers. Other studies have also found high rates of insomnia when withdrawing from nightly use of marijuana. 'At this time there still isn't any clear evidence that cannabis is helping sleep,' said Dr. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota, who was not involved in any of the studies. 'We know that when people initiate use there is some benefit in the immediate short term but there is quick tolerance to this effect,' Kolla said. " There currently is no good quality evidence to suggest that cannabis will help improve sleep quality or duration." CONFOUNDING FACTORS Still, people continue to believe that weed is helping their sleep. Surveys of marijuana users show they do indeed rely on the drug for better sleep. 'The issue is that there's a disconnect between these anecdotal reports of people reporting therapeutic benefits and the evidence behind it in terms of the data,' Diep said. One possible reason, Kolla said, is that when people stop using cannabis after a period of regular use, the withdrawal effects from weed can cause sleep disruptions. That leads people to believe 'the cannabis was in fact helping (sleep), while what they are actually experiencing are withdrawal symptoms.' Another factor to consider is the increased potency of weed today as compared to when many of the studies on cannabis and sleep were conducted, said Dr. Karim Ladha, staff anesthesiologist and clinician-scientist in the department of anesthesiology and pain medicine at the University of Toronto. 'A lot of the older data related to cannabis is based on lower doses of THC than what patients are using now, and there's very little research related to CBD,' Ladha said. 'Studies tell us about what happens at a population level, but on an individual level that discussion is much more personal,' he said. 'The studies just give us the possibilities that (marijuana) could hurt your sleep, but it may help and so we just don't know until you try it." That's why additional studies need to be done, he added. 'Patients are spending money and time and resources to obtain cannabis right now to help with sleep,' Ladha said. 'I think as the medical community, we need to do everything we can to make sure that we enable our patients to make the best possible decisions for their health.'
