Woman, 24, dies of heart attack doing CrossFit competition held in 96F heat
A 24-year-old woman died of a sudden cardiac arrest while competing in a CrossFit competition in held in 96F heat in Mexico.
Nayeli Clemente was taking part in the Cholula Games, a CrossFit licensed event in San Andras Cholula in the south east of the country on May 2.
But during the 'Team Pyramid Run' - a grueling relay-style race where teammates take turns running increasingly longer distances before working back down - Clemente began to find it hard to breathe and fainted.
The fitness enthusiast had to be given emergency CPR by a doctor in the crowd, who was able to briefly stabilize her before an ambulance arrived.
However, she died shortly after arriving at the hospital. Officials later clarified that she had reportedly suffered a sudden heart attack.
While officials are yet to clarify what caused a cardiac arrest, it can be assumed she died due to performing intense exercises in high temperatures.
According to the local press, spectators have claimed that the medical team at the event was slow to respond to Clemente's condition.
Paramedics were allegedly encountered issues when deploying a stretcher and an oxygenation device reportedly was not connected when it was needed.
Some witnesses have also claimed that there were not enough paramedics on site to cover the event - which has led to backlash against organizers of the event.
However, they soon assured people in a statement that they maintained close contact with the family of the young woman.
They said: 'During the main event of the Cholula Games, an athlete developed a medical complication.
'She was treated by the event's medical team and transported alive to a private hospital, where she sadly died the following day.
'The Cholula Games has been in constant communication with the athlete's family since the incident.
'We remain in contact with them to provide them with all the support they need during this difficult time.'
Doctors are warning that working out in excessive heat can increase your risks of a cardiac arrest.
Heat-caused stress to the body can force the cardiovascular system, particularly the heart to work harder to pump blood to the surface of the skin for cooling.
This can lead to to dehydration and electrolyte loss, which can disrupt heart function and raise the risk of death.
Dr Hugh Shoff with UofL Health Emergency Medicine told WDRB: 'If your body is not able to cool itself down, what ends up happening is your organs can't function as well.
'So you start evaporating a lot of water out of your system, then you become dehydrated to where your body can't pump as much fluid and that ends up injuring the organs.'
According to a 2010 study, 95F is considered the upper limit for human survival, beyond which the body cannot effectively cool itself through sweating and becomes susceptible to a cardiac arrest.
Over 350,000 Americans experience cardiac arrest outside of a hospital every year. It typically affects adults, but it can happen in children, too.
Pyramid runs are known to push runners to their limits in terms of endurance and speed due to their structured pattern of running and resting.
However, this exercise can be demanding on the cardiovascular system and muscles - leading to fatigue, excessive sweating as well as damage to your organs.
According to Dr Emil Hodzovic, a Pittsburgh-based doctor and health coach, fitness enthusiasts, whether new or seasoned should not perform intense exercises such as Crossfit during a heatwave.
He said: 'If you experience lightheadedness, hot or red skin, blurry vision, extreme fatigue, weakness, an excessive heart rate or vomiting, then rest in the shade and rehydrate.
'If symptoms persist consult a medical professional. This is not the time for "no pain no gain".'
Additionally, if you are exercising during intense heat, Dr Hodzovic recommends consuming an electrolyte drink before and after your session to make up for lost fluids.
'Hydrate above and beyond what you expect you'll need. Sweat needs to be replaced and you'll lose litres an hour, far more than you can absorb by drinking,' he added.

My night with Israeli paramedics during Iran's worst missile barrage yet
Israel's main emergency dispatch centre for ambulances and paramedics is no ordinary healthcare facility. Buried 15 metres underground, the hardened control room can be sealed with blast doors and sits three floors down in a vast subterranean complex that is more Pentagon than NHS. Overnight on Wednesday, Telegraph reporters were given exclusive access to the high-security facility, which, since Friday, has been responding 24/7 to human damage caused by Iran's missile assault on the Jewish state. It is the headquarters of Magen David Adom (the red star of David), Israel's national ambulance service, one of the most advanced and unusual in the world. It's a place where call handlers are able to pinpoint the impact of missile strikes in real time and dispatch not just ambulances, mobile ICU units and helicopters, but specialist buses capable of carrying seven patients on advanced life support at once. This being Israel at a time of war, many of the emergency responders carry pistols on their belts alongside their tourniquets and stethoscopes. 'We believe we have the best and most advanced emergency service in the world but tomorrow we will be better,' says Elli Bin, MDA's swashbuckling director general. Since the start of Operation Rising Lion - the military name given to Israel's attack on Iran - and the declaration of a state of emergency early last Friday, his crews have responded to strikes that have killed at least 23 and injured more than 700, many with life-changing blast injuries. 'The size of the impacts is what makes this different,' said Israel Weingarten, MDA's deputy director of disasters. 'With the rockets from Gaza and even Lebanon it was contained. Here the blast radius can go to 300 metres or more. 'It means the numbers [of casualties] are higher and it's much more difficult to get to people. We also see many more internal blast, burn and crush injuries'. On Wednesday night, the blast doors of the MDA dispatch centre slammed shut on the dot of midnight as, with the rest of the country, the centre was alerted to the night's first barrage of missiles launched from Iran. As people across Israel dashed for bomb shelters - most in basements - screens lit up across the room with live feeds from news and static cameras across the country. Through these and other means, the centre is able to estimate probable and actual impact points, giving it vital extra minutes to get emergency crews to the scene. 'Speed is everything,' said Ori Lazarovich, 26, a senior paramedic and head of MDA international relations for Europe. 'If you want to save someone haemorrhaging or trapped in a fire every second counts'. On Sunday this week, Mr Lazarovich was among the first to arrive at the massive Bat Yam missile strike near Tel Aviv, where he worked with others to pull survivors from the burning buildings. 'Normally you would wait for the first services to arrive but we were first and had to deal with it,' said the paramedic who first trained with the Israeli Defence Forces. The first batch of missiles on Wednesday night was taken down by Israel's air defence system. But just as the room paused to catch its breath, a second salvo was launched, sparking another seven to eight minutes of frantic activity as the projectiles arched high above Iraq and Jordan before hurtling down towards Israel. And again, the air defence systems locked on, shooting them out of the sky before they could impact. The MDA centre breathed again. For the first three nights of this conflict, several missiles got through from Iran, the size of the barrages seemingly overwhelming Israel's air defences. There was significant damage done to both industrial and civilian infrastructure, with the destructive force of the blasts catching many Israelis by surprise. An oil refinery in the north was set ablaze and shut down, and while Iran had majored on military sites outside of major cities in the attacks launched in April and October last year, now it was hitting major population centres. The Iron Dome and its related air defence systems, which have given citizens a very real sense of protection, were not 'hermetic,' the government went on air to stress. Only an underground safe room could really provide protection. After the second strike in the early hours of Thursday morning, there was a long pause before a third barrage hit just after 7am in the morning. Two, nearly three, days of successful interceptions had built confidence that the Iranian capacity to get through was fading. So much so that lockdown regulations had been relaxed to allow many more businesses to reopen on Thursday morning. But at 7.12am, another 20 missiles started to hit, three of them getting through to cause very significant damage. A major hospital, the Soroka Medical Center in Beersheba in the south of the country, was hit, as were two densely packed housing areas south of Tel Aviv, one at Holon and one at Ramat Gan. The Telegraph raced to Holon where the devastation was immense, and it was a miracle no one was killed. If you had to guess where pictures of the scene came from, many would say Gaza. The missile hit one ageing five-storey block directly, completely demolishing it and leaving the four immediately adjacent buildings without windows and structurally unstable. A 12-floor high-rise had its cladding and glass stripped away from top to bottom on two sides, and even 400 metres away on surrounding streets, the blast had blown out doors and windows. The local synagogue was badly damaged, and a school and three local kindergartens were strewn with rubble. Had they been open, the carnage would have been unimaginable. Professor Alon Ben Nun, a prominent surgeon and medical director of the fire brigades, was early at the scene helping people from their shelters and out of the rubble. 'I would say there were a 100 walking wounded and four seriously wounded,' he said as drones with thermal cameras buzzed overhead searching for unconscious survivors. Gill Vaknin, 57, said he had just got into his building's shared bomb shelter when the missile hit. There was no 'whoosh' of warning, just an 'incredibly loud and powerful blast'. 'It's hard to describe,' he said, 'the whole building shook. If we were not in the shelter I would not be talking to you now'. Barch Angel, a retired machinery operative, 55, was out when the blast hit, but it very nearly killed his wife Dalia. She received an alert on her phone and reached the entrance to the shelter with only seconds to spare. The blast exploded through the plate glass front of the couple's apartment, shredding the main living area and kitchen. Anyone who had been there would almost certainly have died. Dalia could not speak for emotion, while Barch surveyed the damage philosophically. 'I'm fine', he said, 'what's there to worry about. We are safe. The rest is only money'. His son Itzic said the housing estate in Holon was a 'family community... peaceful, a very sleepy place.' 'Everyone in Israel has been affected by the war [since October 7] but this is the closest it has ever got to this neighbourhood physically', he added. The MDA paramedics at the scene were still busy helping people with minor injuries and logistical issues, when the Telegraph left. First responders with MDA, like Batya Tugendhaft, 20, originally from North West London, were visibly exhausted but determined to carry on. 'It's the young that basically run this nation. We are cheap labour, but we do it for a sense of duty to our country and love. This is a true national service,' she said. Even in the darkest of times as a paramedic, 'there are tiny pockets of human connection' that make it worthwhile.

Experts warn summer vacationers of beach seashells so toxic they can 'kill in minutes'
Experts are warning summer vacationers to be on the lookout for a hidden flesh-eating beach threat that could kill them within minutes. Hiding inside some seashells could be a cone snail — a highly venomous sea snail that can sting people with a poisonous toxin. People may unknowingly pick up the snail, which is found in coastal rockpools, after being attracted by its stunningly black-and-white patterned shell. However, if the shell is still inhabited, the snail can harpoon a human with its deadly stinger — injecting a cocktail of toxins that can kill in minutes. The snails can be found across the southern US coasts, but the types that can inject deadly venom have only been found near San Diego, California, and along Mexico 's Pacific coast. Larger snails are more likely to deliver deadly stings, scientists say, while children are more at risk of death from stings due to their smaller size. Some researchers fear the population of the snails, also found in the Indo-Pacific region, is now rising amid warming ocean temperatures. Tina Petway, an associate curator of molluscs at Houston's Museum of Natural Sciences, Texas, is among the lucky few to survive a sting from the snails. Petway was alone on a research trip to the Solomon Islands when she picked up a cone snail and, while turning to pick up another, it stung her three times. She tried to pull the barbs from her skin but, finding she couldn't, she then tried to walk back to her hut — already feeling herself losing vision and consciousness. Entering the hut moments later, she wrote a short note to her husband about what happened, took a lot of antihistamines - medications used during allergic reactions - and then climbed into bed. It was three days before she finally woke up again, and realized that she had just survived the deadly snail attack. 'I realized this other hand was on fire,' she said on TikTok, describing the attack, 'so when I looked I could see where it had stung me three times'. Afterward, she took a two-hour boat ride to the island's airstrip — and then waited there for three days for the next flight to get her off the island. She says she is routinely plagued by headaches ever since suffering the sting, but has not suffered from any other long-term complications. Australian marine snail specialist Dr Stephen Smith previously told ABC: 'It's one of the things that I've certainly instilled in my kids, that you don't pick up cone shells. 'Knowing what a cone shell looks like, the habitat you're likely to find them in… It's something we need to get out there so people are aware of the potential risk of this species.' Cone snails are predators, armed with a deadly harpoon that they use to shoot fish and then inject toxins to immobilize them. They do not hunt humans, but may deliver a sting if someone picks up their shell or accidentally steps on them in a rockpool or in the ocean. There are no good estimates on the number of stings and fatalities caused by the snails in the US or among American vacationers every year, although it is thought to be low. A 2016 study reviewing global data suggested there have been 139 cases of stings reported worldwide, of which 36 were fatal — based on information on cases they could find dating back to the 17th century. It particularly focused on the conus geographus species — identified by its brown cone-shaped shell with white bands or white spots and known on Mexico's Pacific coast — which it said was behind half of all cases and fatalities. 'Children succumb more often to C. geographus stings than adults and stings by larger snails are lethal more often than stings from smaller snails, regardless of the victim's age,' the researchers said. Also of concern is the conus textile — identified by a largely white cone-shaped shell covered with brown triangles — which can similarly deliver a nasty cocktail of neurotoxins in its stings. In many cases, stings from the snails are mild and not dissimilar from one due to a wasp or a bee — causing pain in the area. In some cases, however, this may progress to cyanosis — or blueness at the site due to decreased blood flow — and even numbness or tingling. Doctors say that in severe cases, stings can cause numbness in an entire limb that progresses to a loss of sensation around the mouth and then the entire body. Pictured above is the natural range for conus geographus, the most deadly cone snail Paralysis can then occur, which also affects the lungs — stopping someone from being able to breath. There is no antivenom for the stings, but doctors may treat them by immersing the affected area in water that is as hot as is tolerable — with the hot water potentially helping to denature the venom to make it less deadly. Pressure may also be applied to the affected area, which can help to slow the spread of the poison in the body. They may also inject a local anesthetic into the wounded area to try to ease the symptoms. Patients are advised to stay calm and avoid any excessive movement.
