Survival skills in Irwindale are techniques that a person may use in order to sustain life in any type of natural environment or built environment. These techniques are meant to provide basic necessities for human life which include water, food, and shelter. The skills also support proper knowledge and interactions with animals and plants to promote the sustaining of life over a period of time. Practicing with a survival suit An immersion suit, or survival suit is a special type of waterproof dry suit that protects the wearer from hypothermia from immersion in cold water, after abandoning a sinking or capsized vessel, especially in the open ocean.

Survival skills are often associated with the need to survive in a disaster situation in Irwindale .
 Survival skills are often basic ideas and abilities that ancients invented and used themselves for thousands of years.
 Outdoor activities such as hiking, backpacking, horseback riding, fishing, and hunting all require basic wilderness survival skills, especially in handling emergency situations. Bush-craft and primitive living are most often self-implemented, but require many of the same skills.
Jump to navigation Jump to search Progression-free survival (PFS) is "the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse". In oncology, PFS usually refers to situations in which a tumor is present, as demonstrated by laboratory testing, radiologic testing, or clinically. Similarly, "disease-free survival" is when patients have had operations and are left with no detectable disease. Time to progression (TTP) does not count patients who die from other causes but is otherwise a close equivalent to PFS (unless there are a large number of such events). The FDA gives separate definitions and prefers PFS. PFS is widely used in oncology. Since (as already said) it only applies to patients with inoperable disease[dubious – discuss] that are generally treated with drugs (chemotherapy, target therapies, etc.) it will mostly be considered in relation to drug treatment of cancer. A very important aspect is the definition of "progression" since this generally involves imaging techniques (plain radiograms, CT scans, MRI, PET scans, ultrasounds) or other aspects: biochemical progression may be defined on the basis of an increase in a tumor marker (such as CA125 for epithelial ovarian cancer or PSA for prostate cancer). At present any change in the radiological aspect of a lesion is defined according to RECIST criteria. But progression may also be due to the appearance of a new lesion originating from the same tumor or to the appearance of new cancer in the same organ or in a different organ, or due to unequivocal progression in 'non-target' lesions—such as pleural effusions, ascites, leptomeningeal disease etc. Progression-free survival is often used as an alternative to overall survival (OS): this is the most reliable endpoint in clinical studies, but it will only be available after a longer time than PFS. For this reason, especially when new drugs are tested, there is a pressure (that in some cases may be absolutely acceptable while in other cases may hide economical interests) to approve new drugs on the basis of PFS data rather than waiting for OS data. PFS is considered as a "surrogate" of OS: in some cancers the two elements are strictly related, but in others they are not. Several agents that may prolong PFS do not prolong OS. PFS may be considered as an endpoint in itself (the FDA and EMEA consider it such) in situations where overall survival endpoints may be not feasible, and where progression is likely or very likely to be related to symptomatology. Patient understanding of what prolongation of PFS means has not been evaluated robustly. In a time trade off study in renal cancer, physicians rated PFS the most important aspect of treatment, while for patients it fell below fatigue, hand foot syndrome, and other toxicities. <Park et al> There is an element that makes PFS a questionable endpoint: by definition it refers to the date on which progression is detected, and this means that it depends on which date a radiological evaluation (in most cases) is performed. If for any reason a CT scan is postponed by one week (because the machine is out of order, or the patients feels too bad to go to the hospital) PFS is unduly prolonged. On the other hand, PFS becomes more relevant than OS when in a randomized trial patients that progress while on treatment A are allowed to receive treatment B (these patients may "cross" from one arm of the study to the other). If treatment B is really more effective than treatment A it is probable that the OS of patients will be the same even if PFS may be very different. This happened for example in studies comparing tyrosine kinase inhibitors (TKI) to standard chemotherapy in patients with non-small cell lung cancer (NSCLC) harboring a mutation in EGF-receptor. Patients started on TKI had a much longer PFS, but since patients that started on chemotherapy were allowed to receive TKI on progression, OS was similar. The relationship between PFS and OS is altered in any case in which a successive treatment may influence survival. Unfortunately this does not happen very often for second-line treatment of cancer, and even less so for successive treatments. The advantage of measuring PFS over measuring OS is that PFS appears sooner than deaths, allowing faster trials and oncologists feel that PFS can give them a better idea of how the cancer is progressing during the course of treatment. Traditionally, the U.S. Food and Drug Administration has required studies of OS rather than PFS to demonstrate that a drug is effective against cancer, but recently[when?] the FDA. has accepted PFS. The use of PFS for proof of effectiveness and regulatory approval is controversial. It is often used as a clinical endpoint in randomized controlled trials for cancer therapies. It is a metric frequently used by the UK National Institute for Health and Clinical Excellence and the U.S. Food and Drug Administration to evaluate the effectiveness of a cancer treatment. PFS has been postulated to be a better ("more pure") measure of efficacy in second-line clinical trials as it eliminates potential differential bias from prior or subsequent treatments. However, PFS improvements do not always result in corresponding improvements in overall survival, and the control of the disease may come at the biological expense of side effects from the treatment itself. This has been described as an example of the McNamara fallacy.
What is Fear and how can we manage it?Fear is something that has been bred into us. At one time it served a very useful purpose and still can today. Fear is our way of protecting us from great bodily harm or a threat to our survival. The unfortunate part is that we have generalized fear to the point that we use it in a way that hinders our growth and possibilities. All too often, fear is used as a reason to not follow through on something. Fear has become our protector from disappointment, not from bodily harm, as was intended. No one is going to be physically hurt or die because a business venture failed, or because he or she got turned down for a date, or even if you lose your job.Search your past for times when you have not attained your desired outcome. Maybe it was a test that you failed in University, an idea that got shot down by your boss, losing an important client, or even being fired from your job. Did you die? Did you lose a limb? The answer of course is no. In fact, and for the most part we look back at our disappointments with a certain level of fondness. Sometimes we even laugh about them. We've all said at one time or another, "I'll laugh about this later". Well why wait? Laugh now. Sometimes we even find ourselves in better positions because of our past disappointments. Yet at the time even the mere thought of these types of setbacks paralyze us to the point of inaction. It is natural to feel fear.That doesn't mean that you have to give into it. Jack Canfield, co-author of "Chicken Soup for the Soul" likes to say, "Feel the fear, and do it anyway". Feel the fear, take a deep breath, tell yourself that no bodily harm can come to you as a result of this action, see it for what it is...an opportunity to grow, no matter the result. Acknowledge the fact that your past disappointments have not destroyed you, they have made you stronger. Most importantly, follow through; take the next step toward your goal, whatever it may be. Don't let an instinct that was intended to protect you from great bodily harm, keep you from getting what you want. Learn to manage your fear and see it for what it is...a survival mechanism. Control it...don't let it control you.
