Surge in fatal opioid overdoses in Ontario shelters, report finds

INSTITUTE FOR CLINICAL EVALUATIVE SCIENCES

Researchers from the Ontario Drug Policy Research Network (ODPRN) at St. Michael’s Hospital and Public Health Ontario analyzed health data from the Office of the Chief Coroner of Ontario and ICES, and found that there were 210 accidental opioid-related toxicity deaths within shelters between January 2018 to May 2022, with the number of deaths more than tripling during the study period (48 before the pandemic versus 162 during the pandemic). 

Statistics Canada data shows that the annual number of emergency beds in Ontario grew by only 15% (6,764 to 7,767) between 2018 and 2022. 

“People who use Ontario’s shelter system are not only facing housing instability, but also have complex healthcare needs and unique barriers to accessing treatment and harm reduction programs,” says lead author Bisola Hamzat, an epidemiologist with the ODPRN. “This report underscores the disproportionate impact of the opioid crisis on this population.” 

Trends in shelters differed from rest of Ontario 

When exploring the circumstances surrounding the overdose and death, the data showed that someone was present and able to intervene for only 1 in 10 opioid-related toxicity deaths within shelters, which is lower than in Ontario overall (approximately 1 in 4). However, naloxone was administered most of the time when someone could intervene within shelters. 

In the week before death, nearly half of people who died within a shelter had contact with the healthcare system, and in the five years prior to death, almost 80% had a hospital visit related for a mental health diagnosis, which is much higher than 56% of people in Ontario overall. 

Several factors remained consistent with the rest of Ontario, including the rise of multiple substances contributing to death (such as benzodiazepines and stimulants), a greater tendency toward smoking and inhalation of drugs, and fentanyl from the unregulated drug supply being the most common driver of deaths. 

In a secondary analysis of hotels and motels, the researchers found that opioid-related overdose deaths followed similar patterns to those in shelters but began to decline toward the end of the study period in 2022. The researchers say that the rise in deaths was likely influenced by the rapid expansion of temporary hotel-based shelters early in the COVID-19 pandemic. 

Urgent need for improved response to crisis 

“Our report highlights the need for improved and expanded harm reduction approaches, overdose response, as well as staff training and supports within shelters,” says co-lead author Tara Gomes, a scientist at the Li Ka Shing Knowledge Institute of St. Michael’s Hospital and ICES, and a principal investigator of the ODPRN.  

“Additionally, improved connection to community-based healthcare, treatment programs, and mental health supports are needed for people experiencing homelessness and housing instability, in combination with efforts to address upstream factors such as more accessible housing, income and employment supports, and community-based social supports across the province.” 

“The report highlights what we have witnessed the last few years in Timmins. It demonstrates the need for comprehensive support across the spectrum of care for unhoused community members, and of the importance of shelter design and management to ensure services are accessible and safe for people who use drugs. An increase in deaths in the Timmins shelter system over the past two years serves as a stark reminder of this importance,” says Jason Sereda, President, Board of Directors: DIY Community Health Timmins. 

The report, “Opioid-related toxicity deaths within Ontario shelters: circumstances of death and prior medication & healthcare use” was published on the ODPRN website.

For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.

Astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have varied orientations within one region. Here, however, they are slanted in the same direction, to the same degree, like sleet pouring down during a storm.

 

The discovery of these aligned objects, made possible due to Webb’s exquisite spatial resolution and sensitivity in near-infrared wavelengths, is providing information into the fundamentals of how stars are born.

“Astronomers have long assumed that as clouds collapse to form stars, the stars will tend to spin in the same direction,” said principal investigator Klaus Pontoppidan, of NASA’s Jet Propulsion Laboratory in Pasadena, California. “However, this has not been seen so directly before. These aligned, elongated structures are a historical record of the fundamental way that stars are born.”

So just how does the alignment of the stellar jets relate to the rotation of the star? As an interstellar gas cloud crashes in on itself to form a star, it spins more rapidly. The only way for the gas to continue moving inward is for some of the spin (known as angular momentum) to be removed. A disk of material forms around the young star to transport material down, like a whirlpool around a drain. The swirling magnetic fields in the inner disk launch some of the material into twin jets that shoot outward in opposite directions, perpendicular to the disk of material.

In the Webb image, these jets are signified by bright clumpy streaks that appear red, which are shockwaves from the jet hitting surrounding gas and dust. Here, the red color represents the presence of molecular hydrogen and carbon monoxide.

“This area of the Serpens Nebula – Serpens North – only comes into clear view with Webb,” said lead author Joel Green of the Space Telescope Science Institute in Baltimore. “We’re now able to catch these extremely young stars and their outflows, some of which previously appeared as just blobs or were completely invisible in optical wavelengths because of the thick dust surrounding them.”

Astronomers say there are a few forces that potentially can shift the direction of the outflows during this period of a young star’s life. One way is when binary stars spin around each other and wobble in orientation, twisting the direction of the outflows over time.

Stars of the Serpens

The Serpens Nebula, located 1,300 light-years from Earth, is only one or two million years old, which is very young in cosmic terms. It’s also home to a particularly dense cluster of newly forming stars (~100,000 years old), seen at the center of this image. Some of these stars will eventually grow to the mass of our Sun.

“Webb is a young stellar object-finding machine,” Green said. “In this field, we pick up sign posts of every single young star, down to the lowest mass stars.”

“It’s a very complete picture we’re seeing now,” added Pontoppidan.

So, throughout the region in this image, filaments and wisps of different hues represent reflected starlight from still-forming protostars within the cloud. In some areas, there is dust in front of that reflection, which appears here with an orange, diffuse shade.

This region has been home to other coincidental discoveries, including the flapping “Bat Shadow,” which earned its name when 2020 data from NASA’s Hubble Space Telescope revealed a star’s planet-forming disk to flap, or shift. This feature is visible at the center of the Webb image.

Future Studies

The new image, and serendipitous discovery of the aligned objects, is actually just the first step in this scientific program. The team will now use Webb’s NIRSpec (Near-Infrared Spectrograph) to investigate the chemical make-up of the cloud.

The astronomers are interested in determining how volatile chemicals survive star and planet formation. Volatiles are compounds that sublimate, or transition from a solid directly to a gas, at a relatively low temperature – including water and carbon monoxide. They’ll then compare their findings to amounts found in protoplanetary disks of similar-type stars.

“At the most basic form, we are all made of matter that came from these volatiles. The majority of water here on Earth originated when the Sun was an infant protostar billions of years ago,” Pontoppidan said. “Looking at the abundance of these critical compounds in protostars just before their protoplanetary disks have formed could help us understand how unique the circumstances were when our own solar system formed.”

These observations were taken as part of General Observer program 1611. The team’s initial results have been accepted in the Astrophysical Journal.

The James Webb Space Telescope is the world's premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

[The following is a guest editorial written by Dr Lex van Loon, an assistant professor at the Australian National University and the University of Twente in the Netherlands. He is co-author of a new Frontiers in Physiology article.]

Space exploration has always captivated our imagination, offering the promise of discovering new worlds and pushing the boundaries of human capability. As commercial space travel becomes more accessible, individuals with various underlying health conditions—including heart failure—may soon be among those venturing beyond Earth’s atmosphere. This raises critical questions about the impact of space travel on humans with potential underlying health problems. My recent research, ‘Computational modeling of heart failure in microgravity transitions,’ delves into this issue, offering insights that could shape the future of space travel.

Why study heart failure in space?

The demographic of commercial space travelers is shifting, increasingly including older, wealthy individuals who may not be in optimal health. Unlike professional astronauts, these space tourists typically do not undergo rigorous health screenings or physical training. This shift necessitates a broader consideration of health conditions, such as heart failure, diabetes, and other chronic illnesses, in space mission planning.

Heart failure alone affects over 100 million people globally. Traditionally, space medicine has focused on the effects of microgravity on healthy astronauts. However, the inclusion of non-professional astronauts with preexisting health conditions demands a deeper understanding of how microgravity impacts these individuals. The unique cardiovascular challenges posed by space travel could significantly affect heart failure patients, making this an essential area of study.

Furthermore, heart failure is not a uniform condition and can be broadly categorized into two types. One type involves a weakened heart that cannot pump blood effectively, while the other is characterized by the heart’s inability to relax and fill properly. These differences mean that each type of heart failure presents unique challenges and must be studied separately to understand the specific risks and required countermeasures in a microgravity environment.

The challenges of microgravity

In the microgravity environment of space, the human body undergoes significant changes. One of the most notable effects is the redistribution of bodily fluids, causing what is commonly known as ‘puffy face bird leg’ syndrome. Imagine a person with a swollen, puffy face paired with skinny, almost comically thin legs—like a bird, what’s in the name. This fluid shift results in reduced venous pooling in the legs and increased venous pressure in the upper body. For healthy individuals, the cardiovascular system can adapt to these changes, but for heart failure patients, the risks are substantially higher.

Using computational models to simulate space conditions

Given the lack of real-world data on heart failure patients in space, we turned to computational modeling to simulate the effects of microgravity. We used our previously published 21-compartment mathematical model of the cardiovascular system. By tuning the parameters of this model, we were able to predict how heart failure patients might respond during space travel with a high degree of accuracy.

Our simulations revealed that entry into microgravity increases cardiac output in all individuals. However, for heart failure patients, this increase in cardiac output is accompanied by a dangerous rise in left atrial pressure, which can lead to pulmonary edema—a condition where fluid accumulates in the lungs, making it difficult to breathe.

The path forward

Our research underscores the need for comprehensive health screenings and personalized medical plans for space tourists with underlying health conditions. As commercial space travel becomes more accessible, ensuring the safety of all passengers, especially those with chronic health conditions like heart failure, is paramount.

Moreover, our findings highlight the importance of further research into the long-term effects of space travel on cardiovascular health. Future studies should focus on the prolonged exposure to microgravity and the cumulative impact of comorbidities in heart failure patients.

The role of human digital twins

One promising avenue for future research and safety in space travel is the development of human digital twins. A human digital twin is a highly detailed virtual model of an individual's physiological systems. By creating these digital replicas, we can simulate various scenarios and predict how different conditions, such as microgravity, might affect an individual's health. This approach allows for personalized risk assessments and tailored countermeasures.

For heart failure patients, a digital twin could simulate how their specific heart condition would respond to the stresses of space travel. This personalized model could help identify the most effective pre-flight preparations and in-flight interventions, thereby enhancing the safety and well-being of space tourists with heart conditions.

The dream of space travel is closer than ever, but with it comes the responsibility to understand and mitigate the health risks associated with this new frontier. Our computational modeling provides a critical step toward ensuring that space travel is safe for everyone, including those with heart failure. As we continue to push the boundaries of exploration, integrating advanced technologies like human digital twins will be crucial in protecting the health and well-being of all who venture into the final frontier.

By studying nearby galaxy ESO320-G030, a Northwestern University-led team of international astronomers has discovered extremely powerful rotating, magnetic winds help the galaxy’s central supermassive black hole grow.

The process is strikingly similar to the birth of new stars and planets, which are fed by swirls of gas and dust. The new discovery provides a previously unknown clue to solving the long-standing mystery of how supermassive black holes grow to weigh as much as millions or billions of stars.

“It is well-established that stars in the first stages of their evolution grow with the help of rotating winds – accelerated by magnetic fields, just like the wind in this galaxy,” said Northwestern’s Mark Gorski, who led the study. “Our observations show that supermassive black holes and tiny stars can grow by similar processes, but on very different scales.”

The study was published this spring in the journal Astronomy & Astrophysics.

An expert on the evolution of galaxies, Gorski is a postdoctoral fellow at Northwestern’s Center for Interdisciplinary and Exploratory Research in Astrophysics (CIERA). When the research began, Gorski was a postdoctoral researcher at Chalmers University of Technology in Sweden.

Spying on the Milky Way’s neighbor

Most galaxies, including our own Milky Way, have a supermassive black hole at their centers. How these mind-bogglingly massive objects grow into super sizes has remained an unsolved mystery.

In the search for clues, Gorski and his collaborators looked to relatively nearby galaxy ESO320-G030, located just 120 million light years from Earth. ESO320-G030 is a highly active galaxy, forming stars 10 times faster than the Milky Way. The astronomers examined the galaxy using telescopes at the Atacama Large Millimeter/submillimeter Array (ALMA) Observatory in Chile.

“Since this galaxy is very luminous in the infrared, telescopes can resolve striking details in its center,” said study co-author Susanne Aalto, a professor of radio astronomy at Chalmers University of Technology. “We wanted to measure light from molecules carried by winds from the galaxy’s core, hoping to trace how the winds are launched by a growing — or soon to be growing — supermassive black hole. By using ALMA, we were able to study light from behind thick layers of dust and gas.”

‘Clear evidence of a rotating wind’

To examine the dense gas that closely hovers around ESO320-G030’s central black hole, the scientists studied light from hydrogen cyanide molecules. Using Doppler effect technology, the researchers imaged fine details and trace movements in the gas, which revealed patterns suggesting the presence of a magnetized, rotating wind.

While other winds and jets typically push material away from a galaxy’s central supermassive black hole, the newly discovered wind adds another process, which instead feeds the black hole and helps it grow.

The researchers liken the matter traveling around a black hole to water circling a drain. As matter approaches the black hole, it first collects in a chaotic, spinning disk. There, magnetic fields develop and grow stronger. The magnetic fields help lift matter away from the galaxy, creating a vortex of wind. As matter is lost to the wind, the spinning disk slows, which turns the slow trickle of matter into a stream — meaning that matter flows more easily into the black hole. 

“We can see how the winds form a spiraling structure, billowing out from the galaxy’s center,” Aalto said. “When we measured the rotation, mass and velocity of the material flowing outwards, we were surprised to find that we could rule out many explanations for the power of the wind, including star formation for example. Instead, the flow outwards may be powered by the inflow of gas and seems to be held together by magnetic fields.” 

What’s next?

Next, the researchers plan to study the centers of other galaxies, searching for hidden spiraling outflows.

“In our observations we see clear evidence of a rotating wind that helps regulate the growth of the galaxy’s central black hole,” Gorski said. “Now that we know what to look for, the next step is to find out how common a phenomenon this is. And if this is a stage which all galaxies with supermassive black holes go through, what happens to them next? Far from all questions about this process are answered.”

The study, “A spectacular galactic scale magnetohydrodynamic powered wind in ESO320-G030,” was supported by the Swedish Research Council (grant number 621-2011-4143), the European Research Council and the Nordic ALMA Regional Center node based at Onsala Space Observatory.

The United States’ NASA aims to construct a lunar base through the Artemis program, a manned lunar exploration initiative. However, the practical reality of what general public envision for the space base differs somewhat from well-known science fiction movies. To build a base on the Moon using abundant and diverse construction materials, significant transportation costs are involved. All these materials must be launched from Earth using rockets.

Because transporting construction materials from Earth to the Moon is costly and time-consuming, local materials must be utilized in order to establish a lunar base. One promising method for lunar base construction using local materials is microwave sintering, which solidifies lunar regolith (soil) below its melting point. Research on sintering lunar soil using lasers, solar energy, and microwaves is actively underway worldwide. Among these techniques, microwave sintering is a notable technology being developed by various institutions, including NASA, ESA (European Space Agency), and the Korea Institute of Civil Engineering and Building Technology (KICT, President Kim Byung-suk).

The research team(Dr. Jangguen, Lee, Dr. Young-Jae, Kim, Dr. Hyunwoo, Jin) led by Dr. Hyu-Soung, Shin at the Future & Smart Construction Research Division of the KICT is currently conducting a study on microwave-sintered lunar regolith simulant bricks. This research applies sintering techniques similar to firing ceramics, raising the temperature to create solid bricks. The bricks made from lunar regolith simulant have a strength of over 20 MPa, which is comparable to concrete. Microwave heating depends on the dielectric properties of the material, so a detailed study of the dielectric characteristics of lunar regolith is necessary. Currently, there is insufficient research on how lunar regolith interacts with microwave heating at varying temperatures.

As part of microwave sintering research, the research team investigated the dielectric properties of Korean Lunar Simulant (KLS-1) and ilmenite (iron titanate) at different temperatures. Ilmenite is a mineral abundant on the lunar surface and is known to enhance the efficiency of microwave heating. However, detailed studies on the dielectric properties of ilmenite and its behavior during microwave heating have not been conducted.

The research findings indicate that lunar regolith simulant has the microwave transparent property; making it challenging to heat. However, ilmenite (iron titanate) interacts strongly with microwaves due to its unique crystal structure, allowing rapid heating to high temperatures. Additionally, the analysis of the crystal structures of lunar regolith simulant and ilmenite successfully revealed key factors contributing to the increase in mineral-microwave interactions.

Utilizing a local resource, ilmenite, as a heating element in lunar base construction by using microwave sintering means efficient and rapid production of construction materials. Dr. Young-Jae, Kim from the KICT expressed that this research is expected to be a crucial foundation for the development of microwave technology for future lunar exploration and lunar base construction.

U$ Teachers report worse pay and well-being compared to similar working population

 NEWS RELEASE 18-JUN-2024

RAND CORPORATION

With more working hours and lower average base pay, the well-being of U.S. teachers continues to be worse than that of similar working adults – a consistent pattern since 2021, according to a new RAND survey.

Managing student behavior, low salary and administrative work outside of teaching were the top-ranked sources of stress for teachers in 2024. Teachers reported working an average of 53 hours per week; 15 of these hours – or roughly one quarter of their working hours – were outside of their contracts. This compares to 44 hours per week for similar working adults. Only 36% of teachers said their base pay was adequate compared with 51% of similar working adults.

The RAND State of the Teacher survey is a nationally representative, annual survey of K-12 public school teachers across the U.S. The 2024 survey focuses on teacher well-being and high-interest factors related to job retention: sources of job-related stress, pay, hours worked and intentions to leave. Teacher data is presented in comparison to a separate 2024 American Life Panel companion survey, a nationally representative survey of working adults.

“This is RAND’s fourth consecutive year collecting data that raise concerns about high stress and low pay in the teacher workforce,” said Sy Doan, lead author of the report and a policy researcher at nonprofit, nonpartisan RAND. “Although teacher well-being seems to have stabilized at pre-pandemic levels, our data raise questions about the sustainability of the profession for Black teachers and female teachers in particular.”

Black teachers reported working significantly more hours per week, on average, and were less likely to report satisfaction with their weekly working hours than their peers. They were also less likely to say their base pay was adequate than their peers, to report significantly lower base pay, and to say they intended to leave their job.

Female teachers reported significantly higher rates of frequent job-related stress and burnout than male teachers, a consistent pattern since 2021. Female teachers also reported significantly lower base pay than their male peers but no differences in the number of hours they work per week. 

Teachers who considered their current base salaries inadequate desired a roughly $16,000 increase in base pay, on average, to consider their salary to be completely adequate.

This survey also indicates teachers are about as likely to report intending to leave their as working adults; 22% compared with 24% working adults.

The State of the American Teacher survey was supported by the National Education Association and the American Federation of Teachers.

Other authors of “Teacher Well-Being and Intentions to Leave: Findings from the 2024 State of the American Teacher Survey” are Elizabeth D. Steiner and Rakesh Pandey.

RAND Education and Labor, a division of RAND, is dedicated to providing objective research and analysis that improves social and economic well-being through education and workforce development.

June 22 (UPI) -- A proposed class action lawsuit accuses Disney of inducing workers to sell their California homes and move to Florida to work there as part of an eventually canceled project.

Maria De La Cruz and George Fong in a lawsuit filed Tuesday in Los Angeles County Superior Court say Disney officials in July 2021 told them and about 250 other workers at the Disney park, experiences and product team to choose between moving to Lake Nona in central Florida and losing their jobs.

Both did as part of a planned Disney campus project costing $1 billion in Lake Nona that was canceled after the workers relocated there in 2022. Disney planned to bring 2,000 jobs to the Orlando area, which includes Disney World. Disneyland is located in Anaheim, Calif.

Fong is a Disney creative director and says he sold his family home in Los Angeles, which had been in his family for decades, and stayed in a hotel in Florida while his new home in Orlando was readied.

De La Cruz is a Disney vice president of product design, and says she sold her home in Altadena and moved her family to Florida.

After both relocated, along with other Disney workers, the company canceled the project and told the group of workers to move back to California.

Disney in May 2023 notified workers that "considerable changes have occurred since the announcement of this project, including new leadership and changing business conditions."

Those changes included replacing former Disney CEO Bob Chapek, who announced the Lake Nona campus project. New CEO Bob Iger canceled the Lake Nona project.

Fong says they were given the notice to move back to California within six months of him selling his California home and paying for a new one in Florida.

He says he was forced to sell the Florida home, which was virtually unsellable at first and took four months to find a buyer.

De La Cruz is undergoing the moving process to return to California to resume working at Disney's office in Glendale.

Given the current housing market in California, De La Cruz and Fong say they were forced to buy homes whose qualities are less than they had before the induced selling of their old homes.

They also are paying higher interest rates for their new mortgages.

Fong and De La Cruz accuse Disney of concealment and misrepresentation and say the company's eventual compensation offers were much less than the actual costs.

The plaintiffs want other Disney workers to join the lawsuit to create a class action.

Cyberattack cripples U.S. auto dealerships' operations

By Allen Cone

 Dealersbhips deal with hacking. WDIV.

June 22 (UPI) -- Thousands of car dealers in the United States are struggling to handle virtually all areas of their business, including sales and services, because their software vendor was hacked this week.

CDK Global, a company that provides auto dealerships software for managing sales and other services, was shut down for a third straight day Friday after cyberattacks crippled the platform.

Bloomberg reported a group claiming to have hacked the system is demanding tens of millions of dollars, and the company intends to pay the amount but discussions are subject to change. A Bloomberg source said the hack is believed to be based in eastern Europe.

Roughly 15,000 car dealers depend on CDK's dealer management software to run their businesses. That includes payroll, inventory, customer relations and office operations. Dealers also line up with financing and insurance with the system.

The computer system includes agreements involving rebates and incentives.

WDIV business editor Rod Meloni said "they're flying blind."

CDK has not indicated when its systems will be back up and running. But it could take days, according to PC Mag.

"We are actively investigating a cyber incident," a CDK spokesperson told CBS News. "Out of an abundance of caution and concern for our customers, we have shut down most of our systems and are working diligently to get everything up and running as quickly as possible."

Dealerships on Reddit are sharing that they were relying on spreadsheets and sticky notes to sell customers small parts and make repairs, but no large transactions are being done.

Jeff Ramsey, an executive with Ourisman Auto Group headquartered in Maryland, told CNN the shutdown could cost his dealerships some business. Customers could just find a dealer nearby that's not having these issues and buy a new vehicle there, instead.

"My selling team can hand-write a buyer's order," Brian Benstock, general manager of Paragon Honda and Paragon Acura in Long Island City, New York, told CNN.

Ford is providing assistance to its dealers, including Lincoln.

"Although there is an industry-wide system outage for some dealers who use CDK, Ford and Lincoln customers are able to receive sales and service support due to alternative processes available to our dealers," the company said.

Vehicle repair/mainteenance servucs also are affected.

Tom Maoli, whose dealerships are based out of New Jersey, told Fox Business, his group "has to do everything manually," including putting together the repair order "so they can pay it."

"And then what happens is, when there's parts that need to be used to repair the vehicle, there's an inventory system within CDK and those parts are not being deducted from our systems so when we use parts out of our inventory, alerts won't automatically go to the manufacturers to replenish us with those parts," he said, "They're not getting those alerts so the entire supply chain system is being shut down."

Brookfield Business Partners, a Toronto-based private equity firm, acquired the company in 2022 for more than $8 billion.
