B.C. heat dome led to 3-times as many deaths among schizophrenic people

|
British Columbians living with schizophrenia saw a three-fold increase in deaths during the 2021 heat dome, a new study has found.
Roughly 740 people are thought to have died due to the heat dome. However, those living with chronic disease faced a hefty toll, according to the study led by researchers at the BC Centre for Disease Control (BCCDC) and published in GeoHealth Wednesday.
Michael Lee, a BCCDC epidemiologist and lead author of the study, said schizophrenia, and severe mental illness in general, haven’t been traditionally recognized as an important risk factor for dying during extreme heat events. This, he says, is one of the first studies to shed light on the deadly trend.
“Our most striking and surprising finding was that the risk of death among those with schizophrenia more than tripled during the extreme heat event as compared to more typical summer weather,” said Lee in an interview.
More than 60 per cent of deaths during the heat wave occurred in Metro Vancouver. The BC Coroners Service and past studies from the BC Centre for Disease Control have previously said the hardest hit included older people, those with disabilities, and residents living in neighbourhoods with higher levels of deprivation and fewer green spaces.
The latest study compared more than 1,600 deaths during the 2021 heat wave with more than 6,500 deaths recorded on the same dates in 2012 and 2020. The researchers then looked at 26 chronic diseases to find out how they were associated with death during the heat wave.
People were found to be at higher risk of death if they used substances or suffered from heart disease and chronic obstructive pulmonary disease.
The odds of dying during the heat wave were significantly higher for people with chronic kidney disease, depression and diabetes.
“Schizophrenia was most strongly associated with a higher risk of death during the [extreme heat event],” added the researchers.
How mental illness increases the risk of death during a heat wave is not clear, wrote the authors. Lee said past investigations have suggested people with schizophrenia could be more vulnerable because of antipsychotic medications — important drugs that help people manage a complex disease. The medications can sometimes impact the body’s ability to thermoregulate, and “some people with schizophrenia may lack insight into their health status, and thus may not perceive and respond to overheating,” wrote the researchers.
At the same time, the researchers said those with schizophrenia face “stigmatization, social isolation, economic marginalization, and coincident substance use disorder.” Each condition has been found to increase the mortality risk during a heat event.
Lee said no one risk factor explains the deaths seen during the heat wave. Mental health, poverty, age, social isolation and poor access to green spaces are all “very likely to be intertwined and overlapping with one another.”
The epidemiologist said the whole idea of the study was to figure out who is most at risk, so authorities, family, friends and neighbours we can prepare for the next time a major heat event hits the region — something that’s expected to become more frequent and more severe in the coming decades due to climate change.
“Many of us know people in our lives who do have mental health conditions,” said Lee. “And I think it’s really important for people to connect with them before extreme heat events happen, to see if those people understand that they might be at increased risk, to see if they have a plan in place for staying cool.”
And when temperatures climb, “check in on them,” he added.

Heads up – wood ticks are out and about in the Thompson-Okanagan – Vernon News – Castanet.net


Tick season is back in the Okanagan.
Colin Kennedy came across one of the blood-suckers while taking a walk with his dog.
Kennedy was on the Test of Humanity Trail in Summerland last week and came home with an unwanted passenger – a wood tick.
“I just thought it would be good to report it so people start checking their dogs for ticks now that the weather is getting better,” Kennedy says.
Kennedy also reported the tick to eTick.
Anyone who has lived in the B.C. Interior for any length of time has likely had an encounter with a tick or knows someone who has.
They can be found year round, but are most likely to bite from March to June.
Ticks will lie in wait on a branch or tall grass, waiting for an unsuspecting person or animal to brush by. They then latch onto their victim and bury their heads under the skin.
Staying out of the woods is no guarantee you won’t encounter ticks.
Rob Higgins, an entomologist with the department of biological sciences at Thompson Rivers University in Kamloops, says the most common area to find ticks is on grasslands, but they can be found in urban environments as well.
“You can definitely pick them up in town, even when you think you’re walking in urban areas, because you’re brushing up against grasses on the side of the sidewalks,” he said.
If a tick has bitten you, Higgins says the best way to remove it is to take a pair of forceps or tweezers, slide them under the tick and pull backwards firmly – but not abruptly.
It will often take about 30 seconds of firm pressure to pull the tick out.
The variety most often found in B.C. is the Rocky Mountain wood tick.
Western black legged ticks, a species which Higgins said exists in low numbers in B.C., can carry Lyme disease. Each year, there are around a dozen Lyme cases discovered in the province, but about half those originate from outside the region.
Ticks can also carry other diseases, such as tick paralysis. According to Higgins, this disease mostly affects animals and he said vets and ranchers see cases each year.
Overall, it’s important to be careful, but most ticks in B.C. aren’t harmful.
“People don’t like ticks, fortunately here we don’t need to worry about them a great deal,” he said.
“You definitely want to remove them, you want to keep your eyes on your pets for symptoms of paralysis, but otherwise, we can consider the vast majority of them to be harmless.”

'Pandora's Box': Doctors Warn of Rising Plant Fungus Infections in People After 'First of Its Kind' Case – VICE


A man in India is the first human known to be infected by a fungus called Chondrostereum purpureum, a pathogen that is most well-known for causing a disease called silver leaf in plants, reports a new study.
The patient, who was 61 at the time of the diagnosis, made a full recovery and has not experienced any recurrence of the infection after two years of follow-up observations. However, this “first of its kind” case study exemplifies the risks that fungal pathogens pose for humans, especially now that climate change and other human activities like rampant urbanization, have opened a “Pandora’s Box for newer fungal diseases” by contributing to their spread, according to the study.
Fungal pathogens are having a pop culture moment because they are the source of a fictional disease depicted in apocalyptic game The Last of Us, which was recently adapted into the acclaimed HBO series of the same name. But these microbes are also a real-life scourge that infect about 150 million people every year, resulting in about 1.7 million deaths.
Though millions of fungal species exist, only a very small fraction of them are able to infect animals, including humans, because our bodies present challenges to these invaders such as high temperatures and sophisticated immune systems.
Soma Dutta and Ujjwayini Ray, doctors at Apollo Multispecialty Hospitals in Kolkata, India, have now added one more fungus to that small list of human invaders with their unprecedented report of a C. purpureum infection. The patient, a plant mycologist, had suffered from cough, fatigue, anorexia, and a throat abscess for months before his hospital visit, and was probably exposed to the fungus as a result of his profession.
When conventional techniques failed to diagnose the disease, the pathogen was sent to a World Health Organization center based in India where it was finally identified using DNA sequencing. The case “highlights the potential of environmental plant fungi to cause disease in humans and stresses the importance of molecular techniques to identify the causative fungal species,” according to their recent study in the journal Medical Mycology Case Reports.
“This is a first of its kind of a case wherein this plant fungus caused disease in a human,” Dutta and Ray said in the study. “This case report demonstrates the crossover of plant pathogens into humans when working in close contact with plant fungi. The cross-kingdom pathogenicity demands much work to be done in order to explore insights of the mechanisms involved, thus leading to possible recommendations to control and contain these infections.”
C. purpureum can infect a variety of different plants with silver leaf disease, an often fatal condition that is named after the color that the pathogen induces on the leaves on the hosts. It is the latest in a growing number of fungal pathogens that have infected humans, which are buoyed on in part by human activities, such as urbanization, travel, and commerce.
Human-driven climate change is also accelerating the spread of infectious diseases, including fungal pathogens, by allowing microbes to adapt to higher temperatures (like those in mammal bodies), expand their range, and interact with new hosts in the aftermath of extreme weather events. And though fungal diseases have maintained a lower profile in epidemiology compared to other pathogens, they may be more dangerous than viruses or bacteria in some contexts.
“While viral and bacterial diseases receive most attention as the potential cause of plagues and pandemics, fungi can arguably pose equal or even greater threats,” according to a 2021 study in PLoS Pathogens. “There are no vaccines available yet for fungal pathogens, the arsenal of antifungal agents is extremely limited, and fungi can live saprotrophically, producing large quantities of infectious spores and do not require host-to-host contact to establish infection. Indeed, fungi seem to be uniquely capable of causing complete host extinction.”
In addition to avoiding the spread of new fungal pathogens that can directly infect humans, researchers also point to the damage these diseases can deal to crops and ecosystems that people depend on. For this reason, Dutta and Ray recommend more research into the nature of these infections and strategies to mitigate their spread.
“Cross-kingdom human pathogens, and their potential plant reservoirs, have important implications for the emergence of infectious diseases,” Dutta and Ray said. “Fungi are also responsible for various infections in plants that cause destruction of millions of plants and crops” and “produce toxins that contaminate food and cause acute toxicity.”
“Over the past several decades multiple new pathogenic fungi have emerged,” they concluded. “A notable emergence of the multidrug resistant fungus Candida auris has spread all over the world and has become a significant threat. The worsening of global warming and other civilization activities opens Pandora’s Box for newer fungal diseases.”

Staff reassigned to children’s ICU in Winnipeg, some surgeries postponed: Shared Health – Global News
An influx of kids sick with respiratory illness at the children’s pediatric intensive care unit (PICU) in Winnipeg has forced a staff shakeup that may result in the postponement of some non-urgent surgeries, health officials say.
Shared Health says roughly 10 staff — including some from pediatric surgical and recovery units — are being temporarily reassigned to help at Health Sciences Centre Children’s ICU.

Children’s ER seeing ‘unprecedented’ patient levels in Winnipeg as feds secure more pain medications
Officials say a resurgence in respiratory illness circulating in the province is to blame for an uptick in kids ending up in the hospital’s ICU.
There were 17 kids receiving intensive care in the PICU as of Thursday morning. The PICU’s normal baseline capacity is nine.

“A significant number of these patients were experiencing medically complex cases that were further complicated by respiratory illness, including infants and young children,” Shared Health said in an online statement.
There were 51 patients in the hospital’s neonatal ICU Thursday morning. The normal baseline capacity there is 50.
Meanwhile, Shared Health says the number of kids visiting the ER with influenza-like symptoms has increased from a low of 22 on March 18 to 47 on Wednesday.
