คลิปเตือนใจที่ไม่อยากให้เกิดขึ้นซ้ำ… เด็กชายวัย 8 ขวบจมน้ำอย่างเงียบ ๆ ในสระว่ายน้ำสาธารณะที่เต็มไปด้วยผู้คนในมณฑลหูหนาน ประเทศจีน แต่กลับไม่มีใครสังเกตเห็นในทันที การจมน้ำมักเกิดขึ้นรวดเร็วและเงียบกว่าที่คิด ไม่มีเสียงร้องขอความช่วยเหลืออย่างที่หลายคนเข้าใจ ผู้ปกครองจึงควรสอนทักษะว่ายน้ำและการเอาตัวรอดให้ลูกหลานตั้งแต่เนิ่น ๆ โดยเฉพาะก่อนเข้าสู่ฤดูร้อน #เตือนภัย #ความปลอดภัยทางน้ำ #อย่ามองข้าม A cautionary tale we don't want to see repeated… An 8-year-old boy silently drowned in a crowded public swimming pool in Hunan Province, China, yet no one noticed immediately. Drowning often happens more quickly and silently than expected. There are no cries for help as many mistakenly believe. Therefore, parents should teach their children swimming skills and survival techniques from an early age, especially before summer. #Warning #WaterSafety #DontOverlook

It’s Time to Shift Mindsets: Every Active Shooter Is a Potential Suicide Bomber Be wary of black puffer coats as they’re one of the easiest garments to conceal bombs inside, and Al-Qaeda has shown that repeatedly, including in their December 2023 video teasing their upcoming homeland plot. At least 10% of the attackers in the homeland plot are expected to be suicide bombers. That means you can’t treat an active shooter as “just” an active shooter anymore. You must assume he’s also a suicide bomber because that’s exactly how they designed it. Here are some basic SOPs for civilians and venue staff when a shooter may also be a suicide bomber: (1) Distance is survival: If a bomber is still mobile, the blast radius is the threat. Move away and create as much distance as possible: 30–50 feet minimum, 100+ if available. (2) Don’t rush to “help” the downed attacker: If the attacker drops, do not approach. Many vests use dead-man switches, pressure triggers, delayed chemical binaries, or can be remotely detonated by an overwatch. (3) Also, in the same vein, don’t dogpile an attacker: limit engagement to 1–3 responders to reduce the risk of additional casualties. Focus on controlling the attacker’s hands. The most critical element in any close-quarters fight is using firm, targeted restraint techniques to prevent detonation or access to a weapon. (4) Avoid chokepoints: Stairwells, elevators, and bottlenecks become kill zones in a blast. Keep moving toward open space and hard structure. (5) Expect secondary devices: Al-Qaeda doctrine routinely includes follow-on blasts. Treat abandoned bags, jackets, or dropped items as potential IEDs. (6) Clothing–behavior mismatch matters: Watch for heavy coats indoors or in warm climates, and for uneven weight distribution inside of clothing. Also, watch for attempts to evade placing items on belt scanners. (7) Choose hard cover, not concealment: Concrete, pillars, and engine blocks save lives. Drywall and furniture do not. (8) Communicate the right words: When calling 911, say: “Active shooter, possible suicide vest.” It triggers an immediate tactical shift in response. Law enforcement around the country has been preparing for this scenario, give them a leg up with concise reporting. (9) Control the flow. Push crowds away from the attacker, not toward him. Prevent panic surges toward gunfire as suicide bombers seek density. (10) After evacuation, don’t cluster. Most mass-casualty terrorist attacks anticipate crowds gathering outside. Move far and disperse; attackers often plan waves, and clustering makes you a target for a secondary strike. (11) Bombs may contain caustic chemicals. Stay clear of the area until a full HAZMAT assessment is completed. If you feel weak, dizzy, or unwell, seek medical evaluation immediately.

George Tolis: TAVR, Broken Training, and What's Really Wrong With Cardiac Surgery. Dr. George Tolis, section chief of coronary and general cardiac surgery at Brigham and Women's Hospital, joins Drs. Koka and DiGiorgio for a wide-ranging conversation on the state of cardiac surgery. He makes the case that TAVR — while genuinely transformative for the right patient — is being systematically applied too broadly, driven by industry incentive and the erosion of meaningful surgical consent. He discusses his collaboration with John Ioannidis that found no statistically significant mortality benefit for any new cardiac surgery technique introduced over the past 35 years, the paper's rejection by every major surgical journal, and what he paid out of pocket to make it open access. The conversation moves to the collapse of surgical training — fragmented pathways, work hour restrictions that leave residents unprepared for attending life, an academic promotion system that ignores teaching, and a culture that routes incompetent trainees around rather than out — and closes with a brief on Vasily Kolesov, the Soviet surgeon from Leningrad who performed the world's first documented coronary bypass years before Favaloro, and whose work was buried by the Cold War.

I completed 34 spays and neuters today—before noon. I’m posting every spay and neuter I perform until Texas A&M University stops killing animals for student training. Every veterinary student should graduate having performed at least 50 spays and neuters. Instead, some students are still being trained through terminal labs—killing healthy animals to practice a handful of procedures. Through public records requests, we reviewed Texas A&M protocols that request permission to kill: • 240 dogs • 43 goats • 48 birds Additional protocols include: • Up to 10 horses per year killed for equine surgery training • Turtles pithed—a procedure involving destruction of the brain—for physiology demonstrations that teach no clinical skills and have readily available non-lethal alternatives These animals are not suffering from conditions requiring euthanasia. High-volume spay/neuter, shelter partnerships, and modern teaching tools exist. I did not perform these labs in veterinary school—and I am not a less capable veterinarian because of it. If you are a Texas A&M student or alum and want to share your experience—or challenge this—reach out: [email protected] --- Among the records we obtained from Texas A&M University were the following protocols: · Creation of embalmed cadavers and teaching aids: In this protocol, 240 dogs, 43 goats, and 48 birds are purchased and killed to teach anatomy to veterinary students, graduate students, and undergraduates. These animals are not suffering from conditions necessitating medical euthanasia. · Equine euthanasia for cadaver surgery training: In this protocol, up to 10 horses are killed each year to train veterinary residents. While some horses are donated for euthanasia due to chronic, irreversible illnesses, some are also sourced from internal protocols. · Properties of cardiac muscle (teaching laboratory exercise for VTPP 423 & VTPP 910): Two turtles a year are chemically pithed and used in live demonstrations to demonstrate “electrical and mechanical events of the turtle heart” to veterinary students (additional turtles are also killed to perform this demonstration to undergraduates). Turtles are purchased from a vendor. This demonstration lacks educational merit as it does not teach any clinical skills, nor is there any justifiable reason to perform this demonstration when there are many other ways to teach the principles illustrated using teaching methods that do not involve the killing of healthy animals. · VMID 935-301, Surgery 1: In this protocol, 162 goats and/or sheep are purchased and then used in terminal teaching exercises to teach veterinary students surgical techniques. The instructors justify the protocol by stating that hemostasis techniques cannot be learned in simulators, models, or cadavers, although research has shown that these are effective methods of teaching hemostasis. This is also not a justification for doing terminal surgeries – most other schools successfully teach students castration and ovariohysterectomy as survival surgeries on shelter animals without requiring terminal surgeries as practice. · Reptile and Amphibian Teaching Labs: This protocol is for teaching vet students handling, and procedures on frogs and/or toads. Up to 20 animals are killed per year at the end of the lab. The animals are acquired through vendors, pet stores, or internal protocols. Some may be adopted instead of euthanized, but it is unclear how many survive. The animals used are otherwise healthy. · ACVIM Large Animal Internal Medicine Bootcamp (every two years): This protocol requires up to two horses to be killed and their cadavers used for teaching residents advanced medical procedures. This event appears to take place every two years, although it is unclear if it is still ongoing. The horses are sourced from the university herd and do not appear to be slated for medical euthanasia. Several protocols use mostly donated animals, and we encourage you to expand your donation program, particularly for cadavers. · Animal use for teaching through the Educational Memorial Program: Donated animals are used to create cadavers that are then used in teaching veterinary students, graduate and undergraduate students. The number and species of cadavers depends on availability. · Student Chapter of AAEP: In this protocol, 8 horse cadavers were used for teaching veterinary students from around the country. Procedures taught include laparoscopy, abdominal explore, laceration repair, necropsy, and emergency/critical care. It is unclear if this protocol recurs or if it was a one-time event. Most of the horses were donated for medical reasons, but some were sourced from the university herds, and it is unclear if they were slated for medical euthanasia. · Student Chapters of the American Association of Bovine Practitioners, Small Ruminant Practitioners, and Swine Practitioners skills teaching wetlab: Four terminally ill calves were donated for this lab teaching vet students euthanasia and necropsy skills. It is unclear if this event occurs on a regular basis. #vetmed #vetstudent #vetschool #veterinarian #spayandneuter #vettwitter
