Study attributes 440 ‘excess deaths' to January's Los Angeles wildfires
LOS ANGELES : Wildfires that devastated parts of the Los Angeles area in January indirectly led to hundreds of deaths in the ensuing weeks, far exceeding the official toll of 31 fatalities, according to a study released on Wednesday.
The research, published in the Journal of the American Medical Association, or JAMA, estimated 440 'excess deaths' were attributable to the fires from Jan 5 to Feb 1, using models that compared predicted mortality under normal circumstances to actual numbers documented during that period.
The additional deaths likely reflect a mix of factors, including increased exposure of people with heart and lung disease to poor air quality from smoke and toxins released by the fires, as well as healthcare delays and disruptions, the study said.
The findings 'underscore the need to complement direct fatalities estimates with alternative methods to quantify the additional mortality burden of wildfires and of climate-related emergencies more broadly,' the researchers wrote.
Two wind-driven wildfires that erupted during the first week of January on opposite sides of Los Angeles damaged or destroyed nearly 16,000 structures combined – laying waste to much of the seaside district of Pacific Palisades and the foothill community of Altadena.
Together, the blazes scorched 152sq km, an area larger than Paris.
The official tally of people who perished as a direct result of the fires stands at 31, after the most recent set of human remains were unearthed in Altadena in July, six months after the fires.
Governor Gavin Newsom in February requested nearly US$40 billion in wildfire aid from Congress. Some estimates put economic losses from the fires at more than US$250 billion, making the conflagration one of the most costly natural disasters in US history.
The JAMA study acknowledged some limitations, saying the data may need to be revised upward in the future and the research did not reflect any fire-attributable deaths beyond Feb 1.

307 medical officers to be stationed in Sabah
Health minister Dzulkefly Ahmad meeting patients during his visit to Klinik Desa Karamunting in Sabah today. (Facebook pic) PETALING JAYA : A total of 307 permanent medical officers will be stationed at healthcare facilities throughout Sabah under the first phase of the e-Placement initiative to strengthen services and reduce the existing workload. Health minister Dzulkefly Ahmad said 10 of these officers will serve at the Duchess of Kent Hospital in Sandakan, which is the main referral hospital for the east coast of Sabah, covering not just Sandakan but also Kinabatangan, Beluran, Telupid and Tongod, Bernama reported. 'This hospital offers 19 in-house specialties and is the heart of health services in these five districts. With 414 beds, it faces a high workload covering outpatient treatment, surgery, emergency cases and maternity services. 'The arrival of the new staff will help improve the quality of service for the public,' he said in a Facebook post about his three-day working visit to Sabah today. He said the ministry had approved an allocation of RM1.05 million to carry out minor works and improvements at the hospital. The funds will meet the needs of the surgical ward and help in the purchase of more chairs for patients in waiting areas, mattresses and pillows. He took note of the need for further facility upgrades, such as the construction of a new block, the temporary relocation of old, at-risk wards, and the addition of a large-capacity water tank. The minister later reviewed the operations at Kinabatangan Hospital, including the maternal and child health clinic as well as the dental clinic. He inaugurated the new building of the Ulu Dusun health clinic (KK) in Sandakan and reviewed the progress of the reconstruction of KK Bukit Garam in Kinabatangan under the 12th Malaysia Plan's dilapidated clinic project. The upgrading work for KK Ulu Dusun, valued at RM600,000, has been completed and the clinic is operational while reconstruction of KK Bukit Garam, valued at RM1 million, is ongoing and includes the construction of a new building, complete with basic and support facilities. Dzulkefly is expected to visit 22 health facilities across six districts in Sabah. He wants the services at health clinics to be strengthened to reduce overcrowding at major hospitals. This will be done by moving minor surgeries to health clinics with the involvement of specialists.

Cancer Diaries: Letting go of outcomes, expectations and clutter
AUG 13 — May 2026. That's the earliest mammogram appointment I can get from KL General Hospital While I don't need one so soon (I'm still waiting for a radiotherapy date and mammograms can only be scheduled within six to 12 months after completing the treatment), I'm still a little gobsmacked at how far out that is. Still, I'm not that hard up that I can't afford to pay for a mammogram at a private centre myself if I think it's warranted, so we'll just see how it goes. In other news I still don't have a radiation date and am deciding not to worry too much about my recurrence risk. All those calculated percentages are just possible odds and I would do better to look after myself, not stress myself out, and instead busy myself with one of my multiple hobbies. A friend, trying to be helpful, said that Beacon Hospital 'only' charged RM40,000 for a regular 23-day course of radiotherapy. That's nice and all but spending more than half my annual salary on radiotherapy when I can just wait a few more weeks for a public hospital appointment? I'll just be patient. Recovering from cancer has left me little time or energy to look after my collection of knick-knacks so declutter I must, because I struggle to bend over to dust low shelves. It's a pain having too many interests and hobbies because I only have one bank account. I went on a Facebook group for gifting things and gave away a large portion of my doll collection. One mother told me that her son had always wanted boy dolls but she hadn't had money to spare for them — now he and his sister can play with their dolls, formerly mine, together. Play, I think, is vital. Children need to be allowed to be children instead of, as a former minister suggests, being rushed into finishing school as soon as possible so they can be new bodies for the workforce. Play broadens the mind, exercises the imagination and even colours the future. Child me used to look into a mirror and pretend I was reporting for 'live' TV and while I never ended up in broadcast journalism, I think that desire to 'report' things has never gone away. Recovering from cancer has left me little time or energy to look after my collection of knick-knacks so declutter I must, because I struggle to bend over to dust low shelves. — Unsplash pic My canes are no longer a real help for me these days so they have gone to a nice senior citizen recovering from hip surgery. One of my spare photography lamps that keeps falling over on me when I try to clean my spare room is also going to a new owner. I have enough things in my life trying to kill me, thank you. Of course some self-righteous people would declare maybe if I'd been more frugal I'd have been able to self-fund my cancer treatment. That's laughable — what I spent on my dolls wouldn't cover even a tenth of what I've had to spend on my diagnosis alone. Unless you earn a five-figure salary and live like a monk, it's next to impossible now to save enough for a major medical emergency. The worst thing is that insurance isn't even guaranteed to cover your procedures being a gamble in itself (that your insurance provider won't screw you over) so for most of us public healthcare remains a saving grace. It's distressing that the government won't approve further health spending to 'not increase national debt', implying that it's perfectly OK instead to let Malaysians instead go into debt to stay alive. Then we have Indonesia clamouring to send their nurses over here which might quickly fill up positions, but I wonder how those foreign nurses will be able to live on wages that Malaysian nurses find untenable. It's also been eye-opening for me seeing on cancer forums people being near-hysterical at the mere mention of chemotherapy. The problem, I think, is that people see the side effects of cancer treatment more than they see what happens when people die of untreated cancer. You know why that is? Because cancer patients die and don't hang around long enough for the public to witness what happens when you try and cure cancer with wishful thinking. I feel a little guilty sometimes because I've tolerated the treatment and drugs fairly well, not even getting nauseous and running a fever only once, very briefly. My legs and hands are still stiff but I find I can go down stairs a little easier, if I warm my legs up beforehand. I don't know what the future brings and if my cancer will return, but what I will do is marvel that right now I'm alive and cake tastes good again.

‘Silent Killer': Experts reveal the underestimated dangers of rising global heatwaves
PARIS, Aug 13 — As Europe and North America endure or brace for yet another wave of sweltering heat and out-of-control wildfires this summer, experts are sounding the alarm over heat stress. The condition kills more people than hurricanes, floods or any other climate-related extreme, but what is heat stress exactly, and how is it measured? 'Silent killer' Heat stress occurs when the body's natural cooling systems are overwhelmed, causing symptoms ranging from dizziness and headaches to organ failure and death. It is brought on by prolonged exposure to heat and other environmental factors that work together to undermine the body's internal thermostat and its ability to regulate temperature. 'Heat is a silent killer, because symptoms are not so easily evident. And when these underlying conditions are present, the consequences can be very bad, and even catastrophic,' said Alejandro Saez Reale of the World Meteorological Organisation (WMO). Infants, the elderly, people with health problems and outdoor workers are particularly vulnerable. City dwellers surrounded by concrete, brick and other heat-absorbing surfaces also face an elevated risk. The WMO estimates that heat kills around half a million people a year but says that the true toll is not known, and could be 30 times higher than is currently recorded. As climate change makes heatwaves longer, stronger and more frequent, people across the planet will be increasingly exposed to conditions that test the limits of human endurance. More than a maximum Temperature might be the most widely used and easily understood weather reading, but headline-catching 'maximum highs' do not fully tell how heat might affect the human body. For example, 35 degrees Celsius feels very different in the dry heat of the desert compared to the humid climes of a jungle. To build a more complete picture, scientists consider a host of factors including temperature but also humidity, wind speed, clothing, direct sunshine, and even the amounts of concrete or greenery in the area. All these play a big role in how the body perceives and, most importantly, responds to extreme heat. There are many ways to measure heat stress, some of which are decades old, but all try to boil down different environmental readings into a single number or graph. 'Feels like' One of the oldest methods is known as wet-bulb temperature, a useful gauge in situations where the thermometer reading may not seem too extreme but when combined with humidity becomes unbearable, even lethal. Just six hours exposed to 35 degrees Celsius with 100 percent humidity is enough to kill a healthy person, scientists said in 2023. Above this limit, sweat cannot evaporate off the skin, and the body overheats and expires. Copernicus, the EU's climate monitor, uses the Universal Thermal Climate Index (UTCI), which considers temperature and humidity but also wind, sunshine and radiated heat to rank heat stress levels from moderate to extreme. Extreme heat stress, as judged by this index, is a 'feels like' temperature of 46 Celsius and above, at which point it is necessary to take action to avoid health risks. The Heat Index, used by the US National Weather Service, offers an 'apparent temperature' based on heat and humidity in the shade, and a colour-coded graph denoting the likelihood of illness from exposure. Canada has developed the Humidex rating, which combines heat and humidity into one number to reflect the 'perceived temperature' and presents the associated risk in a four-step 'guide to summer comfort' chart. Limitations Other examples of 'thermal stress' indices include the Tropical Summer Index, Predicted Heat Strain and the mean radiant temperature. They are not without limitations, and heatwave expert John Nairn said that some measures worked better in some climates than others. 'It's not the same all around the world, about the way you approach it,' Nairn told AFP. The UTCI, for example, is excellent at reading heat stress in Germany, where it was first developed, but 'a very poor measure' in global south countries, he said. 'It saturates and over-measures far too much. And it would over-alert for those communities who are chronically exposed to heat,' said Nairn, who has advised governments and the WMO on heatwave policy. These locations might receive better heat stress readings using wet-bulb temperature, he said. These indices also do not consider the impact of heat beyond health, he said, even though a heatwave could strand trains or overload air-conditioners. 'If your heat challenge is such that it gets to a level where your infrastructure is not going to operate, and it starts failing, that will have a return on humans no longer being protected,' Nairn said. — AFP
