Province says video visits with doctors will save time for patients

Toronto, ON - More Ontarians will be able to have “video visits” with doctors over the next year as the provincial government takes the first steps to offering more digital health care as part of the strategy to end hallway health care, says Health Minister Christine Elliott. Changes to modernize communication between patients and health care providers will include secure messaging, online booking of appointments, better access for Ontarians to their own health care records and allowing care providers to look at patients’ full online records under new privacy rules. Patients should talk to their doctors to see if visits can be done from the comfort of their living rooms over their computers or smartphones, Elliott said Wednesday at Credit Valley Hospital in Mississauga. “If it’s something really difficult and complicated they’ll still need to have an in-person visit,” she said. “But for many people who just want to have a quick consult with their doctor, the virtual care visits are going to save them a lot of time.” The province will spend an additional $3 million this year to compensate physicians for video visits. Doctors at Credit Valley are already using video links to consult with patients and colleagues at other sites in the Trillium Health Partners network of hospitals. The Ontario Telemedicine Network facilitates similar connections between doctors and patients in northern and rural communities. Through proposed amendments to the Personal Health Information Protection Act, new Ontario Health teams being formed to oversee care for patients will be able to collect, use and share information from individual patients so they don’t have to tell their medical stories “over and over and over again,” Elliott said. This will help various providers involved with a patient to provide more “integrated” care, she added.

Sweeping new B.C. regulations on vape products

Victoria, BC – British Columbia has announced new rules on vape products, including higher taxes, restrictions on sales and advertising, limits on nicotine content and constraints on packaging. Beginning in the spring of 2020, vapour pods and liquids will only be allowed to contain 20 milligrams of nicotine per millilitre, and will have to be sold in plain packaging with health warnings. Flavoured products will only be sold in vape-specific shops with age restrictions, and no advertising will be allowed in public spaces like bus shelters or parks where young people gather. The tobacco tax rate will also be increased by two cents beginning in Jan. 1, while the government will introduce legislation to increase the PST on vaping products from 7 per cent to 20 per cent. The PST increase will apply to cannabis vape juice once legal sales begin later this year, but other cannabis products will continue to be taxed at seven per cent. Health Minister Adrian Dix, Education Minister Rob Fleming and Finance Minister Carole James announced the new regulations at a news conference Thursday morning. "Some vaping manufacturers are using flavours and advertising to entice and normalize vaping for youth — introducing a new generation to very high levels of a very addictive drug," Dix said in a news release. "As a result, youth vaping rates are rising, putting them at risk for addiction and serious illness." The province stopped short of banning flavoured products, as some states have done. Dix said B.C. will prohibit some flavours that "clearly attract young people," but those have yet to be defined.

The effects of marijuana smoking on lung function in older people

Vancouver, BC – A study by WC Tan, Jean Bourbeau and SD Aaron, into the effects of marijuana smoking on the elderly, was recently published in the European Respiratory Journal. In order to determine how lung function is influenced in the long-term by smoked marijuana, the researchers undertook a study with 5,291 population-based people, including a subset of 1,285 men and women (aged 40 years and older) who self-reported use (or nonuse) of marijuana and tobacco cigarettes. They examined the link between marijuana smoking and the risk of spirometrically-defined COPD [post-bronchodilator FEV1/FVC < 0·7] in 5,291 participants. They also assessed the rate of decline in FEV1 in the abovementioned subset. Findings revealed an increase in the risk of COPD among heavy marijuana smokers. In concomitant tobacco smokers, heavy marijuana smoking accelerated FEV1 drop beyond that observed with tobacco alone.

Bone mineral density in emphysema in hospitalized male COPD patients

Konya, Turkey – A study, led by B. Yormaz of Selcuk University, Faculty of Medicine, Department of Pulmonology, Konya, Turkey was recently published in The Journal of Clinical Respirology, looked at bone density in men with COPD. Since an increased risk of osteoporosis in COPD is normally overlooked, particularly in male patients, therefore, researchers here compared male COPD patients with emphysema and the chronic bronchitis phenotype with respect to bone mineral density (BMD) measurements. They assessed the link between density of emphysema and osteoporosis. In this prospective analysis, they analyzed 94 patients with COPD, and with emphysema and the chronic bronchitis phenotype. Among patients with emphysema and bronchitis, osteoporosis was present in 60.47% and 17.65% and osteopenia was found in 27.91% and 41.18% of patients, respectively. In patients with osteoporosis, high resolution computed tomography emphysema density was negatively correlated with bone densitometer t-score, and BMI was positively correlated with the bone densitometer t-score. Independent risk factors for a low BMD were BMI and emphysema score. Experts recommended assessment for osteoporosis in particularly male patients with emphysema, high dyspnea score, low BMI and frequent exacerbations.

Playing harmonica is therapy for Veterans with COPD

Tampa, FL - A new class offered by James A. Haley Veterans’ Hospital is offering Veterans the chance to make music while treating their breathing problems. The COPD Foundation and the Academy of Country Music for individuals with Chronic Obstructive Pulmonary Disease created the Harmonicas for Health program. COPD is a catch-all term that includes people diagnosed with illnesses like emphysema, asthma and chronic bronchitis. According to Dave Folds, the breathing used to play the harmonica is similar to the breathing exercises used in therapy for COPD. Folds is the Health Promotion-Disease Prevention Coordinator. “Harmonicas for Health is using a musical instrument to use the same inhale-exhale exercises used by pulmonary rehabilitation to strengthen the diaphragm muscles,” Folds explained. “Basically, the breathing exercises are pursed lips-style breathing, like breathing in and out of a straw. Breathing through a straw would be the same way you would blow in and out of a harmonica.” Veterans who enroll in the class are given their own harmonica, a music book and literature on COPD. They meet as a class once a week and are asked to continue to practice at home. Folds, who is also the class instructor, said being able to use the harmonica at home is one of the major benefits of this program. “By making music, it’s much more enjoyable than sitting at home for half an hour each day breathing in and out of a straw,” Folds said. “Most of the people in this class won’t do that for a half an hour, and they say so. But they will sit at home and practice their harmonica, some of them for hours.” Besides the physical benefits of the program, participants also often experience social benefits. “These are people who oftentimes don’t go anywhere without an oxygen bottle. Or they don’t go anywhere because they feel self-conscious about saying one or two words and then taking a breath,” Folds said. “They tend to be not shut-ins, but stay-at-homes. This is an opportunity for them to get out, talk with one another, socialize and meet new people.” Folds asks Veterans to commit to the program for 12 weeks. That allows them to pick up enough instruction and practice to be able to play simple songs so they’re more likely to continue with the harmonica at home after leaving the class. Army Veteran Don Gilbreath was diagnosed with COPD 12 years ago. He has been participating in Harmonicas for Health for 12 weeks and says he can feel the difference the class has made in that time. “I feel a difference and have more endurance. I won’t do the pursed lips exercises at home. All I do is just sit there, breathe in, breathe out. But with the harmonica, you’re actually achieving something and hopefully getting pleasant sounds out of it. “You’re getting the reward for the effort you put in, and that’s the one thing I really like about it. Even after class, I’ll take it home and practice because I see an improvement in my breathing.”

Study finds vaccine effectiveness reduces hospitalizations in elderly

Atlanta, GA - Vaccination is the best way to prevent influenza; however, greater benefits could be achieved. To help guide research and policy agendas, researchers here, led by Michelle M Hughes, aimed to quantify the magnitude of influenza disease that would be prevented through targeted increases in vaccine effectiveness (VE) or vaccine coverage (VC). For 3 influenza seasons (2011–12, 2015–16, and 2017–18), researchers used a mathematical model to estimate the number of prevented influenza-associated illnesses, medically attended illnesses, and hospitalizations across 5 age groups. Compared with estimates of prevented illness during each season, given observed VE and VC, we explored the number of additional outcomes that would have been prevented from a 5% absolute increase in VE or VC or from achieving 60% VE or 70% VC. They concluded that small, attainable improvements in effectiveness or VC of the influenza vaccine could lead to substantial additional reductions in the influenza burden. Improvements in VE would have the greatest impact in reducing hospitalizations in adults aged ≥65 years, and VC improvements would have the largest benefit in reducing illnesses in adults aged 18–49 years.

Mice that vaped nicotine for a year had a dramatic increase in tumor growth, study finds

New York, NY - New research in mice suggests that long-term exposure to vaping liquids that contain nicotine greatly increases the risk of cancer. After breathing in the vapor for 20 hours a week for more than a year, 22.5% of the mice had cancerous tumors in the lining of the lungs, and 57.5% developed growths in their bladder tissue that can be precursors to cancer. Meanwhile, only 5.6% of mice in a control group that breathed only filtered air wound up with lung tumors, and none of them had growths in their bladders. In addition, a group of mice exposed to aerosolized vaping chemicals without nicotine developed no lung tumors, and just 6.3% of them had precancerous bladder growths. The scientists who conducted the study stressed that much more research is needed to know whether vaping leads to cancer in humans. But they hope their findings, published Monday in the journal Proceedings of the National Academy of Sciences, will make people think twice before trying e-cigarettes, which are widely perceived by teenagers and young adults as a safe alternative to smoking. “Right or wrong, millions of young people are using these right now, and the long-term, population-wide studies won’t be able to report out results for another decade,” said study leader Moon-Shong Tang, an environmental health expert at NYU School of Medicine. “We needed credible evidence to guide people in their choices, and it is unambiguous that nicotine alone will cause damage to the cells that make up organs, including lungs,” said Tang, who has studied how tobacco smoke promotes cancers of the lung and bladder. “Now, we can try to find measures to prevent incidents of e-cigarettes causing cancer.” Vaping has been linked to heart attacks, seizures and burns from exploding devices. And a growing outbreak of at least 1,080 vaping-related lung injuries serves as a stark reminder that it’s too soon to know whether e-cigarettes are a safe alternative to smoking. To get a better idea of the long-term effects of nicotine, Tang and his collaborators exposed 45 mice to an aerosol of nicotine dissolved in isopropylene glycol and vegetable glycerin, a common vehicle for vaping liquids. Another group of 20 mice was exposed to the same vehicle without nicotine. For 54 weeks, the animals were subjected to the aerosol mixes for four hours per day, five days per week. A third group of 20 mice spent their time in a room with ambient filtered air. (The study was limited to 54 weeks in order to minimize the effects of age-related cancers that could have cropped up occurred regardless of exposure to e-cigarette vapor.) Five mice in the group exposed to nicotine died over the course of the year. So did two of the mice in each of the other groups. When the 54 weeks were up, the remaining animals were killed and the researchers examined their tissues. Nine of the 40 mice in the nicotine group had tumors in their lungs, compared with none of the 18 mice that breathed the nicotine-free aerosol and one of the 18 mice exposed to filtered air. (Tang said he wasn’t surprised that a tumor was found in the control group, since mice typically have increased rates of lung cancer.) In addition, the researchers found that 23 of the 40 mice that inhaled the vapor with nicotine developed bladder hyperplasia, an out-of-control cell reproduction in the lining of the bladder that often precedes cancer. That compares with 1 out of 16 mice that inhaled vapor without nicotine and zero out of 17 mice that breathed filtered air. (Tissue samples from three of the mice were accidentally destroyed and could not be included in the analysis.) The differences were large enough for the researchers to conclude that the aerosolized vaping liquid with nicotine was responsible for the increased risk of tumors. For instance, the mice that inhaled the nicotine mixture were eight times more likely to develop lung tumors than the mice in the other two groups that weren’t exposed to nicotine. “This is compelling, and very scary,” said Dr. Mark Litwin, the chair of UCLA’s Department of Urology. “When the instructions encoded in DNA get mangled, the cells go on a craze and continue multiplying, unable to control themselves. That’s a hallmark of cancer. And at a glance, this already looks like precancer tissue.” The researchers also found that a few of the mice exposed to e-cigarette vapor — with or without nicotine — developed abdominal or skin tumors, while none of their counterparts in the filtered-air group did. However, those differences were small and could have been due to chance.

B.C. seniors face up to 2-month wait for more effective flu vaccine

Victoria, BC - Seniors in B.C. will have to wait longer for a flu vaccine that offers them better protection, because the province doesn't cover the vaccine, according to the vaccine's manufacturer. The Fluzone High-Dose vaccine isn't expected to land on shelves in B.C. until the end of November or early December, the B.C. Pharmacy Association said Tuesday. Fluzone High-Dose vaccine produces a stronger immune response in seniors who are vulnerable to the flu. Standard vaccines are expected to arrive in October. The vaccine, which Health Canada approved in 2015 for use in people aged 65 and older, contains four times the antigen of a standard flu vaccine and produces a stronger immune response in seniors. A 2014 study found the high-dose vaccine to be 24 per cent more effective in preventing the flu than standard vaccines in adults 65 or older. Seniors are more vulnerable to the flu because of their weaker immune systems. Adults 65 and older accounted for up to 90 per cent of seasonal flu-related deaths in recent years, and up to 70 per cent of seasonal flu-related hospitalizations, according to the U.S. Centers for Disease Control and Prevention. B.C. covers standard flu vaccines but does not publicly fund the high-dose version. Pharmacies in the province charge $75 for the shot.The vaccine's manufacturer, Sanofi Pasteur, said it prioritizes delivery of vaccines to provinces and territories that publicly cover the vaccine, including Ontario, Manitoba, Saskatchewan, Northwest Territories, Nova Scotia and Prince Edward Island. Ontario is the only province that offers the vaccines to all seniors. The other provinces and territories distribute the vaccines to people living in long-term care.

Influenza Vaccine Effectiveness in Preventing Hospitalizations in Older Patients With Chronic Obstructive Pulmonary Disease

Toronto, ON - Annual influenza immunization is recommended for people with chronic obstructive pulmonary disease (COPD) by all major COPD clinical practice guidelines. Researchers here recently sought to determine the seasonal influenza vaccine effectiveness (VE) against laboratory-confirmed influenza-associated hospitalizations among older adults with COPD. They conducted a test-negative study of influenza VE in community-dwelling older adults with COPD in Ontario, Canada using health administrative data and respiratory specimens collected from patients tested for influenza during the 2010–11 to 2015–16 influenza seasons. Influenza vaccination was ascertained from physician and pharmacist billing claims. Multivariable logistic regression was used to estimate the adjusted odds ratio of influenza vaccination in people with, compared to those without, laboratory-confirmed influenza. They found that receipt of seasonal influenza vaccine was associated with an adjusted 22% (95% confidence interval [CI], 15%–27%) reduction in laboratory-confirmed influenza-associated hospitalization. Adjustment for potential misclassification of vaccination status increased this to 43% (95% CI, 35%–52%). Vaccine effectiveness was not found to vary by patient- or influenza-related variables. The researchers concluded that during the studied influenza seasons, influenza vaccination was at least modestly effective in reducing laboratory-confirmed influenza-associated hospitalizations in people with COPD. The imperfect effectiveness emphasizes the need for better influenza vaccines and other preventive strategies. The study was led by Andrea S Girshon, Sunnybrook Health Sciences Centre, Toronto.

Increased Synthetic Cannabinoid Use Found in Older Adults With COPD

Toronto, ON - Older adults above the age of 66 with chronic obstructive pulmonary disease (COPD) were found to be twice as likely to use prescription synthetic oral cannabinoids when compared with adults of the same age without COPD, according to a study published this week in the journal Drugs & Aging. Research led by Saint Michael’s Hospital in Toronto and the Institute for Clinical Evaluative Sciences (ICES) sought to examine the frequency of synthetic oral cannabinoid use, human-made versions of THC such as nabilone and dronabinol, in patients with COPD. Previous studies by the study group have revealed that other psychoactive drugs such as opioids and benzodiazepines have been frequently used for care related to COPD, which were correlated to a potential increase in mortality risk. Currently, safety recommendations advise against prescribing cannabinoids in patients with COPD. However, due to the effects of THC in the central nervous system which produce effects such as sedation and pain relief, many patients and physicians are turning to its use to manage symptoms. Researchers analyzed information obtained from a retrospective, population-based, cohort study on 172,282 adults with COPD and 1,068,256 older adults without COPD all aged 66 or older: Physician-diagnosed COPD identified using previously validated, highly specific algorithm Incident off-label oral cannabinoid use examined between April 1, 2005 and March 31, 2015 Descriptive statistics used to describe drug use patterns and multiple logistic regression used to identify characteristics correlated to incident drug use. Data from the study unveiled a significantly greater frequency in incident synthetic oral cannabinoid use for patients with COPD versus without (0.6% vs 0.3%; P < .001). When compared to older adults without COPD who use synthetic cannabinoids, patients with COPD exhibited increased high dosage frequency and significantly longer usage duration. Study results additionally found that cannabinoids were used more frequently in subgroups of older adults with COPD at a heightened risk for adverse events, such as patients receiving other sedating psychiatric medications and those with psychiatric disease. Lead study author Nicholas Vozoris, MD, a respirologist at Saint Michael’s and an associate scientist at Li Ka Shing Knowledge Institute and ICES, highlighted the study’s findings while also stressing for precaution. “Our study showed that patients and clinicians are turning to cannabinoids more frequently to manage the symptoms associated with COPD, but little is known about the potential dangers associated with this medication class,” said Vozoris. The management of prescribed doses, especially in patients with COPD is vital considering the study’s indication of their high dosage and longer duration use. “Though the use of these drugs isn’t too frequent today, without careful monitoring of the way they’re being prescribed and used now, we could end up with larger problems in the future,” said Vozoris. The study authors noted that further research into the respiratory safety of cannabinoid use is warranted among individuals with COPD. “We’d like [clinicians] to reflect on their own prescribing practices and ensure cannabinoid drugs are used and prescribed with vigilance,” said Vozoris.

Pelosi offers Medicare negotiation plan to curb drug prices

Washington, DC - House Speaker Nancy Pelosi, trying to seize the agenda on a top consumer issue, announced an ambitious prescription drug plan last week that would allow Medicare to negotiate prices for seniors and younger people. The proposal would direct Medicare to bargain over as many as 250, but no fewer than 25, of the costliest drugs. Insulin is on the list. Drug-makers that refuse to negotiate could face steep penalties. Companies that raise prices beyond inflation would have to pay rebates to Medicare. The plan would limit copays for seniors covered by Medicare’s “Part D” prescription drug program to $2,000 a year. Medicare-negotiated prices would be available to other buyers, such as employer health plans. It’s shaping up as a high-stakes gamble for all sides in Washington. Polls show that high drug prices have Americans worried, and regardless of party affiliation, they want Congress to act. As a candidate, President Donald Trump called for Medicare negotiations but later seemed to drop the idea. Pelosi, D-Calif., said her goal is a deal that Trump can sign onto and that could pass the GOP-controlled Senate. “We don’t want a political issue at the polls,” Pelosi said at a news conference. “We want a solution in Congress, and we want it now.” Pelosi’s proposal would authorize Medicare to negotiate prices for up to 250 drugs with the greatest total cost to society. That includes pharmacy drugs under the Part D prescription benefit, and Part B medications dispensed in doctors’ offices, such as many cancer drugs. Medicare would negotiate for as many drugs as possible on a list refreshed annually, but no fewer than 25. The maximum price would be determined using a blend of international prices, similar to a more limited proposal from the administration. Drug companies that balk at making a deal would face penalties that start at 65% of sales for the drug at issue. Currently, Medicare’s pharmacy benefit has no cap on copays, and the advent of drugs costing hundreds of thousands of dollars a year has left some seniors saddled with bills that rival a mortgage payment.

Winter virus season impact on acute dyspnoea in the emergency department

Toulouse, France – A study led by Christiaens H, et al. recently published in The Clinical Respiratory Journal looked at the impact of breathlessness during virus season on the use of emergency departments in hospitals. In this monocentric retrospective cohort study, researchers compared the epidemiology of dyspnoea presented to emergency departments (EDs) during and of winter virus season (WVS). Participants included all patients visiting the ED of the Rangueil University Hospital (Toulouse, France) for dyspnoea in September 2016 (off WVS period) and January 2017 (during WVS period). During the WVS period, they noted a doubling of the incidence of patients visiting because of dyspnoea. Significantly older patients with more extensive medical backgrounds and more serious diseases visited the ED because of dyspnoea during WVS period. They realized a large requirement of hospitalization in this time-consuming population, which is possibly responsible for emergency department's overcrowding during epidemics.

Program launched to combat e-cigarette use

New York, NY - In response to alarming levels of e-cigarette use among youth in the United States—including a 78 percent increase among high school students in just one year—Bloomberg Philanthropies today announced the creation of a new $160 million initiative to end the youth e-cigarette epidemic. Goals of the initiative, “Protect Kids: Fight Flavored E-Cigarettes,” include banning all flavored e-cigarettes—and stopping Juul and other e-cigarette companies from marketing their products to children. The three-year program will be led by the Campaign for Tobacco-Free Kids, which will partner with other leading organizations including parent and community groups concerned about the nation’s kids and health. More than 3.6 million middle and high school students in the United States use e-cigarettes, accounting for about one-third of all U.S. e-cigarette users. E-cigarettes with kid-friendly flavors such as mint, mango, gummy bear and cotton candy are fueling this epidemic; 97 percent of kids who use e-cigarettes use the flavored varieties, and 70 percent report the flavors as the reason they use e-cigarettes. Teen smoking rates in the United States declined by more than 70 percent between 2000 and 2018, but the spike in e-cigarette use among youth threatens to undo a generation’s worth of progress. The creation of the initiative comes as health authorities in 33 states are investigating more than 450 cases of severe respiratory illnesses associated with vaping, with many cases involving teens and young adults. A CDC health advisory released in response to these alarming incidents encourages e-cigarette users to stop using these products while investigations into the cause of these illnesses are ongoing. Recently the Food and Drug Administration said that Juul, the leading e-cigarette company, has violated federal regulations by promoting its tobacco products as healthier than traditional cigarettes. E-cigarettes are uniquely dangerous for kids due to nicotine’s highly addictive properties and its impact on their developing brains: adolescent exposure to nicotine can reduce attention, learning and memory. Juul—which now represents over 70 percent of the e-cigarette market in the United States—delivers high levels of nicotine, with each Juul pod delivering as much nicotine as a pack of 20 cigarettes. There is also substantial evidence that e-cigarette use increases the risk of using combustible tobacco cigarettes among youth and young adults. “E-cigarette companies and the tobacco companies that back them are preying on America’s youth. They are using the same marketing tactics that once lured kids to cigarettes, and the result is an epidemic that is spiraling out of control and putting kids in danger of addiction and serious health problems,” said Michael R. Bloomberg, Bloomberg Philanthropies Founder. “The federal government has the responsibility to protect children from harm, but it has failed – so the rest of us are taking action. I look forward to partnering with advocates in cities and states across the country on legislative actions that protect our kids’ health. The decline in youth smoking is one of the great health victories of this century, and we can’t allow tobacco companies to reverse that progress.” The initiative will support local advocacy efforts in cities and states including legislative and regulatory measures to: Remove flavored e-cigarettes from the marketplace. Researchers have identified more than 15,000 e-cigarette flavors available online. In addition to the role flavored products have played in driving the youth e-cigarette epidemic, studies have found that some flavoring chemicals may also have health risks.

Optimism boosts exceptional longevity

Washington, DC - The National Academy of Sciences recently released a study that examined the relationship between optimism and longevity. Studies regarding exceptional longevity, defined as living to age 85 or older, have largely focused on biomedical rather than psychological factors. To examine the effects of optimism on exceptional longevity, Lewina O. Lee and colleagues analyzed data from 69,744 women from the Nurses' Health Study and 1,429 men from the Veterans Affairs Normative Aging Study. The women's age range was 58-86 years when they completed an optimism assessment in 2004, and their mortality status was tracked through 2014; the men's age range was 41-90 years when they completed an optimism assessment in 1986, and their mortality status was tracked through 2016. The authors found that higher optimism was associated with increased odds of exceptional longevity, even after taking into account other relevant factors, such as demographics, health conditions, and health behaviors. On average, more optimistic individuals demonstrated 11-15% longer lifespan than less optimistic individuals. The findings suggest that optimism may be an important factor for healthy aging, according to the authors.

Flu vaccine associated with reduced risk for death, stroke in elderly ICU survivors

Aarhus, Denmark - In Denmark, elderly ICU survivors who received an influenza vaccine had an 8% decreased risk for death and a 16% reduced risk for hospitalization for stroke in the year after discharge compared with patients who were not vaccinated, according to findings from a population-based cohort study published in Intensive Care Medicine. “Patients aged 65 years or older who survive a hospitalization with intensive care admission are at high risk of morbidity and mortality within the first year after discharge,” Christian F. Christiansen, MD, PhD, associate professor of clinical epidemiology at Aarhus University Hospital in Denmark, told Infectious Disease News. “Our study shows that there are fewer deaths and strokes within the first year after discharge in intensive care survivors who have been vaccinated against influenza compared with unvaccinated individuals.” According to Christiansen and colleagues, 1-year mortality after hospital discharge among ICU patients aged 65 years or older ranges between 21% and 27% — three to four times higher than the mortality rate for the general population of the same age. As more critically ill elderly patients are admitted to ICUs and surviving intensive care, “long-term morbidity and mortality after the immediate critical illness are major concerns in this fragile population,” and any benefits from influenza vaccination among these patients would have a significant clinical impact, they noted. The researchers analyzed data from the Danish Intensive Care Database from 2005 through 2015 and included 89,818 ICU survivors aged 65 years or older in the study. The patients who were vaccinated for influenza (n = 34,871; 39%) were older, used more prescription medications and had more chronic diseases than the unvaccinated patients, according to the study. Vaccinated patients had an adjusted 1-year mortality of 19.3% vs. 18.8% for unvaccinated patients (adjusted HR = 0.92; 95% CI, 0.89-0.95), Christiansen and colleagues reported. Vaccination also was associated with a decreased risk for stroke (adjusted HR = 0.84; 95% CI, 0.78-0.92), but the researchers found no association between vaccination and subsequent hospitalization for pneumonia or heart failure. “We can only speculate about the potential mechanisms as our study did not provide such data,” Christiansen said. “There is growing evidence linking infection and inflammation to cardiovascular events, and it is possible that preventing influenza infection may decrease the risk of cardiovascular events, including stroke. Others suggest a nonspecific immunomodulatory effect of the vaccine itself, which may influence the outcome of critical illness.” Christiansen said the study’s findings support current recommendations that influenza vaccination be provided to high-risk groups, including individuals aged 65 years or older.

Doctors suspect vaping behind dozens of lung illnesses in US

New York, NY - As many as 50 people in at least six states have come down with breathing illnesses that may be linked to e-cigarettes or other vaping products. No deaths have been reported, but at least a few have come close.Some patients have likened onset of the illness to a heart attack, and others to the flu. Symptoms have included shortness of breath, fatigue, chest pain and vomiting. Doctors say the illnesses resemble an inhalation injury, with the body apparently reacting to a caustic substance that someone breathed in.Dr. Melodi Pirzada, a pediatric lung specialist at NYU Winthrop Hospital in New York, said she’s seen two cases this summer — one of them an athletic 18-year-old who almost died. “We’re all baffled,” Pirzada said. The only common factor was they had been vaping, she said. Wisconsin health officials said they’re seen 15 confirmed cases, with another 15 illnesses under investigation. New York state officials are investigating 10, Illinois has seen at least six, and Minnesota doctors this week said they have four more. California and Indiana have also been looking into reported illnesses. Health officials have only been counting certain lung illnesses in which the person had vaped within three months. Most are teens, but some adult cases have also been reported. No single vaping device or liquid is associated with the illnesses. Dylan Nelson, a 26-year-old Wisconsin man, went to see a doctor when he first became ill. He has asthma, was diagnosed with pneumonia and was treated and released. Within a few days, he could barely breathe. He went to a hospital and was put on a breathing tube. His two brothers kept a round-the-clock vigil over him in the ensuing days, and at one point one called his mother to the hospital, saying: “Mom, I don’t think he’s going to make it. ... He can’t die without his mom.” He rallied and was released from the hospital late last month. But “he still has lung damage and heart damage,” and doctors still don’t know how much they’ll heal, said his mother, Kim Barnes of Burlington, Wisconsin. Electronic cigarettes have been described as a less dangerous alternative to regular cigarettes, but health officials have been worried about kids using them. Most of the concern has focused on nicotine, which health officials say is harmful to developing brains and might make kids more likely to take up cigarettes. But some vaping products have been found to contain other potentially harmful substances, including flavoring chemicals and oils used for vaping marijuana, experts say. Wisconsin officials did do not know the names of the products the sick people had vaped, but added they could include several substances, including nicotine and THC — the main active chemical in marijuana. Dr. Anne Griffiths, a lung specialist who saw all four of the reported Minnesota cases, said each had vaped different products.

New transplant tech extends organ life outside human body

Vancouver, BC - The Ex Vivo Lung Perfusion Program is centred around a new machine at Vancouver General Hospital that is paving the way for surgeons to provide better, stronger donor lungs with faster access to life-saving transplants. The lung perfusion system allows lungs to live outside the body for up to 12 hours after retrieval. A set of lungs that might otherwise be rejected for transplant can be reassessed, even repaired and reconditioned in a bubble-like machine using  bloodless oxygenated liquid and a ventilator to force air in and out of the lungs. What it means for patients represents a sea change in both the number of available donors, and the length of the average wait time. Last year, doctors at VGH performed 50 double lung transplants. Using ex vivo, that number is expected to increase to about 60, according to the B.C. Lung Transplant Program. The hope is to also reduce patient deaths on the transplant wait list. A bronchoscope is inserted into the airway of a set of donated lungs to clear away infected material. This is one of the ways in which lungs are reconditioned prior to transplant. "We are constantly striving to save more lives and provide better care through innovation," said provincial executive director Ed Ferre. "The Ex Vivo Lung Perfusion Program offers hope to all those on the wait-list." The B.C. Lung Transplant Program at VGH is one of four such programs in Canada and offers life-saving treatment for end-stage lung disease.

ECMO use outpacing mechanical ventilation in lung transplantation

Addison, Texas - In the past decade, the use of extracorporeal membrane oxygenation as a bridge to lung transplantation has increased significantly, whereas the use of mechanical ventilation has steadily decreased, researchers reported in The Journal of Heart and Lung Transplantation. Importantly, they added, this surge in use of ECMO has been accompanied by a significant improvement in survival that places the technique on par with mechanical ventilation.  “Until now, the traditional bridging strategy has been mechanical ventilation. After having undergone an iterative evaluation over a decade ago, [mechanical ventilation] as a bridge achieved outcomes that improved enough to allay initial safety concerns,” the researchers wrote. “Comparatively, ECMO was once considered a contraindication to [lung transplantation]. However, ECMO use has undergone a period of scrutiny and evolution to ultimately gain acceptance as a potentially acceptable contemporary bridging option. The improvement in technological design, use of membrane oxygenators and clinical expertise have each greatly enhanced its safety profile.” Using data from the Scientific Registry of Transplant Recipients (SRTR) Standard Transplant Analysis and Research files, the researchers evaluated 21,576 patients (mean age, 54 years; 41% women) who underwent lung transplantation in the U.S. from 2005 to 2017. Patients were analyzed according to whether they received pretransplant mechanical ventilation (n = 1,129), ECMO (n = 664) or no bridge (n = 19,783) and within the context of the early era (2005-2011; n = 11,004) or late era of use (2012-2017; n = 10,572). From the early to the late era, ECMO use increased from 1% to 5% (P < .001) as use of mechanical ventilation decreased from 6% to 4% (P < .001). Moreover, the median lung allocation scores of patients in the late era were higher than in the early era (37.5 vs. 36.1; P < .001). Although the risk for 1-year mortality was higher in both the mechanical ventilation (HR = 1.9; 95% CI, 1.64-2.2) and ECMO groups (HR = 1.93; 95% CI, 1.56-2.53) than in the no-bridge group, direct comparison demonstrated no significant differences between the two bridging strategies (HR = 0.99; 95% CI, 0.78-1.25). Five-year mortality risk was also higher with mechanical ventilation (P < .001) and ECMO (P < .001), as compared without bridging, but again, there was no difference between the two when directly compared (P = .817). Similar patterns regarding mortality risk with bridging vs. no bridging were noted in both the early and late eras, according to the data; however, analyses in the ECMO group only showed that the risk for 1-year mortality with ECMO decreased in the later era (HR = 0.5; 95% CI, 0.32-0.78). When compared with ECMO, patients who received mechanical ventilation were less likely to have ventilator support within 48 hours (P = .003), dialysis (P = .003) and postoperative ECMO (P = .006), but were more likely to be reintubated (P = .005). Length of stay, however, did not differ between the mechanical ventilation and ECMO groups. “There appears to be an improvement in the outcomes with ECMO, distancing itself somewhat from the prohibitive morbidity of the past and demonstrating a growth in volume that has now superseded that of mechanical ventilation. The use of ECMO is safe in this high-risk population. The increasing use of ECMO as a bridge to lung transplantation highlights the need to further define criteria and practice guidelines with which to steer clinical practice, accreditation and reimbursement,” the researchers wrote.

WHO says not enough people protected from smoking

Geneva, Switzerland - Many governments are making progress in the fight against tobacco, with 5 billion people protected by comprehensive tobacco control policies. But a new WHO report shows many countries are still not adequately implementing policies. 2.6 billion people remain unprotected, leaving them at risk of harms caused by tobacco use. Only 1 in 5 people are protected by complete tobacco smoking bans in indoor public spaces and workplaces. 6 in 10 tobacco users want to quit and with proven help, they can more than double their chances of quitting. “Quitting tobacco is one of the best things any person can do for their own health,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. Currently, there are an estimated 1.1 billion smokers, around 80% of whom live in low- and middle-income countries. Many governments are making progress in the fight against tobacco, with 5 billion people today living in countries that have introduced smoking bans, graphic warnings on packaging and other effective tobacco control measures - four times more people than a decade ago. But a new WHO report shows many countries are still not adequately implementing policies, including helping people quit tobacco, that can save lives from tobacco. The seventh WHO Report on the global tobacco epidemic analyses national efforts to implement the most effective measures from the WHO Framework Convention on Tobacco Control (WHO FCTC) that are proven to reduce demand for tobacco. These measures, like the “MPOWER” interventions, have been shown to save lives and reduce costs from averted healthcare expenditure. The MPOWER report was launched in 2007 to promote government action on tobacco control strategies. The focus of the latest report is on the progress countries have made to help tobacco users quit. It is being launched today in Brazil, a country that has become the second, after Turkey, to fully implement all the MPOWER measures at the highest level of achievement. Dr Ghebreyesus said governments should implement cessation services as part of efforts to ensure universal health coverage for their citizens. “Quitting tobacco is one of the best things any person can do for their own health. The MPOWER package gives governments the practical tools to help people kick the habit, adding years to their life and life to their years.” Progress is being made, with 2.4 billion people living in countries now providing comprehensive cessation services (2 billion more than in 2007). But only 23 countries are providing cessation services at the best-practice level, making it the most under-implemented MPOWER measure in terms of number of countries offering full coverage. Tobacco cessation services include national toll-free quit lines, “mCessation” services to reach larger populations via mobile phones, counselling by primary health care providers and cost-covered nicotine replacement therapy. Michael R. Bloomberg, WHO Global Ambassador for Noncommunicable Diseases and Injuries  and founder of Bloomberg Philanthropies, said the report shows government-led efforts to help people quit tobacco work when properly implemented. “More countries are making tobacco control a priority and saving lives, but there’s still much more work to be done,” said Mr Bloomberg. “The WHO’s new report shines a spotlight on global efforts to help people quit using tobacco and it details some of our most important gains.” The report, funded by Bloomberg Philanthropies, showed that while only 23 countries have implemented cessation support policies at the highest level, 116 more provide fully or partially cost-covered services in some or most health facilities, and another 32 offer services but do not cost-cover them, demonstrating a high level of public demand for support to quit. Tobacco use has also declined proportionately in most countries, but population growth means the total number of people using tobacco has remained stubbornly high. Currently, there are an estimated 1.1 billion smokers, around 80% of whom live in low- and middle-income countries (LMICs).

CRP test can guide antibiotic use in COPD

Oxford, UK - Point-of-care C-reactive protein (CRP) testing conducted to inform antibiotic prescribing in patients with chronic obstructive pulmonary disease (COPD) exacerbations was associated with lower overall antibiotic use, and with no evidence of increased harm, according to U.K. researchers. Fewer patients with acute COPD exacerbations in the CRP-guided treatment group were prescribed antibiotics at initial general medical practice consultation (47.7% vs 69.7% in the usual care group) and after the first month of follow-up (59.1% vs. 79.7%), reported Christopher C. Butler, MD, F.Med.Sci, of the University of Oxford in England, and colleagues. Between-group differences in scores on the Clinical COPD Questionnaire (CCQ) during follow-up were not clinically meaningful, suggesting that lower antibiotic use in the CRP-guided arm did not impact patient-reported, disease-specific quality of life during the weeks following initial consultation, they wrote in the New England Journal of Medicine. "The evidence from our trial suggests that CRP-guided antibiotic prescribing for COPD exacerbations in primary care clinics may reduce patient-reported use of antibiotics and the prescribing of antibiotics by clinicians," the authors stated. They noted that primary care physicians are the main prescribers of antibiotics for patients with COPD experiencing exacerbations, and that roughly half of patients living with COPD have one or more acute exacerbations of the disease annually, while approximately one in four patients have two or more exacerbations each year. "More than 80% of these patients receive antibiotic prescriptions in the United States and in Europe," they wrote. "Although many patients who have acute exacerbations of COPD are helped by these treatments, others are not." CRP is a well recognized biomarker for assessing COPD exacerbations that can readily be measured at the point of care, the researchers wrote. They hypothesized that CRP testing could reduce unnecessary antibiotic prescriptions for COPD exacerbations in the primary care setting. They tested the theory in a study involving 653 COPD patients seeking treatment for acute exacerbations at 86 general practice offices in the U.K. Clinicians were given guidance on how to interpret CRP test results, but they were also told that antibiotic prescribing decisions should be "based on a comprehensive assessment of likely risks and benefits, given a patient's underlying health status and clinical features." Based on findings from a 2012 study of antibiotic efficacy in COPD exacerbations, the clinicians were told that antibiotics were unlikely to benefit patients with CRP levels <20 mg/L. They were further told that antibiotics may benefit patients with CRP levels of 20 to 40 mg/L, "mainly, if purulent sputum is present," and that treatment with antibiotics was likely to benefit patients with CRP levels >40 mg/L. Two primary outcomes were assessed in the study: patient-reported antibiotic use within 4 weeks of study randomization and COPD-related health status, as measured by CCQ, 2 weeks after randomization. "Since we would need to show both a reduction in antibiotic use and no worsening of COPD-related health status in order for us to consider the CRP point-of-care test to be effective, we designed this study to answer both questions," Butler and colleagues wrote. They reported that antibiotic use was lower in the point-of-care CRP testing group (57.0% vs 77.4%, adjusted odds ratio 0.31, 95% CI 0.20-0.47). Also, at 2 weeks, the adjusted mean difference in CCQ score was −0.19 points (two-sided 90% CI −0.33 to −0.05) in favor of the CRP-guided group. At initial consultation, fewer patients in the CRP-testing group were prescribed antibiotics (47.7% vs 69.7%, for a difference of 22.0 percentage points, adjusted OR 0.31, 95% CI 0.21-0.45). A similar difference of 20.6 percentage points favoring the CRP-testing group was seen at 4 weeks follow-up (adjusted OR 0.30, 95% CI 0.20-0.46). The investigators concluded that the death of two patients in the usual care group within 4 weeks of study randomization was due to causes unrelated to trial participation.

Very difficult flu season may be on the horizon

Toronto, ON - Health ministry says it has ordered 300,000 more high-dose flu vaccines for this year. This year's flu season will likely be a bad one, Ontario's health minister said Monday, and the province is stocking up on extra high-strength vaccines in preparation. "We expect that it's going to be a very difficult year," Christine Elliott said after an unrelated announcement. "Based on what's happening in Australia we sort of take a look at what's likely to happen in Ontario." Australian health authorities are reporting an early flu season — unusually high activity for this time of year. Though the overall severity is reported as low, hospitalizations are three times what is normal for this time, and there have been more than 200 deaths so far, according to that country's department of health.  Ontario has already ordered 300,000 more doses of high-dose flu vaccines than last year, bringing the total order to 1.2 million doses, said a spokesman for Elliott.  'The anti-vaxxer theory is out there' That vaccine has four times the amount of antigens than the regular flu shot and is given to more vulnerable people, such as seniors. It can be provided in hospitals, long-term care homes and by primary care providers. Elliott said it was proven particularly effective last year, and that the government will also be rolling out an advertising campaign, encouraging people to get the flu shot. "It's really important to prevent it in the first place, but we also need to be prepared to deal with it when it does strike Ontario, both in terms of hospital care, home care and community care," she said. "We will be advertising to people that we want them to get out and get the flu shot and deal with some of the myths out there about  getting the flu vaccine because ... the anti-vaxxer theory is out there as well as far as the flu vaccine is concerned, too." Elliott did not yet have a specific date when the flu shot will be available, but she said it will be well in advance of flu season. Researchers reported early this year that the previous flu season's vaccine appeared to be highly effective. The analysis by researchers with the Canadian Sentinel Practitioner Surveillance Network and published online in the journal Euro Surveillance, shows it was 72 per cent effective in preventing infection with the H1N1 respiratory virus  overall across all age groups.  In the 2018-19 flu season, 34 per cent of adults in Canada aged 18-64 got the flu shot, and 70 per cent of seniors got it, according to the Public Health Agency of Canada.

Importance of patient choice in inhaled medication decision making

Toronto, ON - Asthma Canada and COPD Canada recently partnered to develop a white paper on the importance of patient choice. Some of the key points made in the report include: 

- Inhaled medications are the cornerstone of therapy for both asthma and COPD.

- Therapeutic guidelines help in the selection of safe and effective drugs; the selection of the device must also be patient-centered.

- There is abundant evidence that optimized patient outcomes, minimized exacerbations and maximized adherence are obtained only with careful patient-device alignment; this entails consideration of patient device preferences, physical constraints on device use, and regular inhaler technique education.

- Patients strongly prefer to have trusted health care practitioners who understand and incorporate their preferences when managing their care.

- Medication and device choices/switches should only be conducted by prescribers, with patient knowledge, consent and training, to support adherence and optimize outcomes.

- Drug or device restrictions or switches implemented for cost reasons should never compromise disease control or patient well-being. While budget and sustainability concerns are important to all parties, enforced or encouraged switches among non-equivalent respiratory devices are neither health-based nor patient-focused.
