Heat exhaustion is caused by water and salt depletion from heavy sweating during prolonged exposure to high temperatures. The symptoms include confusion, dark urine, dizziness, fainting, fatigue, headache, muscle cramps, nausea, pale skin and profuse sweating. Heat stroke occurs when the body is unable to regulate its temperature, with a temperature over 40.6 degrees Celsius, and it may be accompanied by confusion and lack of sweating. To prevent heat illness, one should drink plenty of water, get enough sleep, slow down in hot weather, add salt to meals and tell a supervisor if feeling unwell. Treatment involves immediately cooling down, resting in air conditioning, drinking fluids and using cooling measures like showers.

Heat Illness prevention, protection and recovery
Heat illness can grab anyone in most every industry and out-of-work activities. Presenter is a coach outside of work, a Safety, Health and Wellness professional, and has seen both athletes and workers fall victim to heat. This presentation uses facts from a variety of sources along with his first-hand experience.
Heat and heart
This document discusses how heat affects the cardiovascular system and provides precautions. Heat can cause dehydration, directly damage heart and blood vessel cells, and affect blood pressure. Dehydration impacts the heart by causing hypotension, tachycardia, arrhythmias from electrolyte imbalances, and thicker blood with reduced flow. It is important to drink plenty of water and electrolyte drinks to prevent dehydration. Those most vulnerable include the elderly, those with heart conditions, and those on certain medications like diuretics. Symptoms of heat-related illnesses from mild to severe include fatigue, dizziness, nausea, and fainting to confusion and organ failure. Proper precautions include light clothing, staying cool,
Environmental factors in exercise and sports performance
Then there are factors such as the temperature, allergens, pollution and altitude that cannot be controlled and can have serious effects on human performance. Environmental factors such as temperature during competition can hinder performance if not taken seriously. The average body temperature is 37°C
TRAINING AND RACING IN HEAT AND HUMIDITY
This document discusses the physiological effects of training and racing in heat and humidity. It notes that exercise in hot and humid environments increases core temperature and sweat rate. Performance is impaired due to factors like hyperthermia and reduced muscle blood flow. However, heat acclimatization through repeated exercise in hot conditions promotes adaptations like increased plasma volume and sweat rate that improve heat tolerance and performance. Maintaining proper hydration is important to prevent dehydration, which can significantly reduce exercise capacity.
Ice Bath-WBC (1)
Whole body cryotherapy is more effective than ice baths for recovery from injuries. Cryotherapy exposes the body to extremely cold air between -220°F and -280°F for 2-3 minutes, causing rapid vasoconstriction that shunts blood away from the skin to protect internal organs. This enriches the blood and can improve circulation and immune function. In contrast, ice baths immerse the body in cold water for 15-20 minutes, forcing the body to expend energy warming blood and risking hyperthermia if cooling is too great. Cryotherapy allows for immediate return to exercise while ice baths require 12-24 hours of recovery.
Heat Injury Prevention
This document defines various types of heat injury including heat edema, heat rash, sunburn, heat tetany, heat syncope, heat cramps, heat exhaustion, and heat stroke. It identifies factors that influence heat injury such as acclimatization, physical fitness level, fatigue, food and alcohol consumption, and medications. Prevention of heat injuries requires monitoring the wet bulb globe temperature index and ensuring soldiers are properly acclimatized, hydrated, and rested.
Heat Stress 2009
Heat stress can cause severe illness and death. Proper precautions and training are needed to work safely in hot conditions. Employers should develop a heat illness prevention program that includes providing shade and water, training workers on heat illness signs and first aid, and allowing new workers to gradually adjust to hot environments over 10-14 days. Recognizing and promptly treating heat rash, cramps, exhaustion and stroke is critical. Workers should drink water regularly, avoid caffeine and alcohol, and rest in shade to prevent heat-related illness.

This document discusses initiatives by National Ambulance in the United Arab Emirates to improve outcomes for patients experiencing cardiac arrest. It found that applying elements of the cardiac arrest chain of survival, including bystander CPR, use of an automated external defibrillator, and mechanical chest compressions, increased rates of return of spontaneous circulation. Over a six month period, National Ambulance responded to 232 cardiac arrest cases and was able to achieve an overall return of spontaneous circulation rate of 5.2%, with a higher rate of 3.9% when bystander CPR was provided. The study demonstrates that early application of systematic chain of survival steps can positively impact cardiac arrest survival.
Proof of concept of Video Laryngoscopy Intubation: Potential utility in the p...
This study evaluated the use of video laryngoscopy (VL) with two different types of screens by emergency medical technicians with no prior intubation experience. Twenty technicians used direct laryngoscopy (DL) and the two VL methods on a manikin. VL with a distal screen had comparable intubation times, success rates, and difficulty ratings to DL. VL with an attached screen took longer, had lower success rates, and was rated as more difficult. The study suggests VL with a distal screen may help less experienced providers but more research is needed to determine if it provides benefits for emergency technicians in the field.
Damage Control Symposium 24th Nov 2014
The one-day Damage Control Symposium in Dubai discussed current strategies for damage control resuscitation, following the ATLS ABCDE approach. Key topics included prioritizing airway management over GCS criteria, using permissive hypotension and haemostatic resuscitation to control bleeding, and techniques for lung and neuroprotection to prevent further injury in trauma patients. Experienced clinicians shared practical considerations for implementing these strategies during pre-hospital care and in the emergency department.
Sepsis
Sepsis is a life-threatening condition that arises when the body's response to infection causes injury to its own tissues. Globally, sepsis kills about 8 million people annually. Early recognition and treatment are key to improving outcomes. The first hours after diagnosis are especially critical, as mortality increases by about 8% every hour that antibiotics are delayed. Prompt administration of broad-spectrum antibiotics and fluid resuscitation can significantly reduce mortality from sepsis.
EMT Pharmacology Review
This document provides an overview of pharmacology for EMT students. It defines key terms like pharmacodynamics and discusses drug mechanisms of action. The document reviews factors influencing drug response and lists medications EMTs can administer, along with their routes, times of effect, and brief descriptions. Examples are provided for calculating pediatric doses. Responsibilities for medication administration and important legal concepts are also covered.
Extract from 2010 ECC Guidelines: Clopidogrel
Clopidogrel is an oral drug that irreversibly inhibits platelet aggregation through a different mechanism than aspirin. Several studies since 2005 have shown that clopidogrel reduces combined rates of cardiovascular mortality, nonfatal heart attack, and stroke when used in addition to aspirin and anticoagulants for patients with non-ST-elevation or ST-elevation acute coronary syndrome. Clopidogrel increases the risk of major bleeding, especially for patients undergoing coronary artery bypass grafting within 5-7 days. The guidelines recommend a clopidogrel loading dose for moderate and high risk ACS patients but the ideal dose for patients over age 75 is still unclear.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
