Best Rated Survival Foods With Long Shelf Life 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".[1] 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).[2] The FDA gives separate definitions and prefers PFS.[3] PFS is widely used in oncology.[4] 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.[citation needed] 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.[5] It is a metric frequently used by the UK National Institute for Health and Clinical Excellence[6] 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.[citation needed] 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.[7] This has been described as an example of the McNamara fallacy.[7][8] Survival And Cross Jump Rope - Premium Quality

Bush-craft and primitive living are most often self-implemented, but require many of the same skills. Main article: Wilderness medical emergency A first aid kit containing equipment to treat common injuries and illness First aid (wilderness first aid in particular) can help a person survive and function with injuries and illnesses that would otherwise kill or incapacitate him/her. Common and dangerous injuries include: The survivor may need to apply the contents of a first aid kit or, if possessing the required knowledge, naturally occurring medicinal plants, immobilize injured limbs, or even transport incapacitated comrades. Main article: Bivouac shelter Shelter built from tarp and sticks. Pictured are displaced persons from the Sri Lankan Civil War A shelter can range from a natural shelter, such as a cave, overhanging rock outcrop, or fallen-down tree, to an intermediate form of man-made shelter such as a debris hut, tree pit shelter, or snow cave, to completely man-made structures such as a tarp, tent, or longhouse. Making fire is recognized in the sources as significantly increasing the ability to survive physically and mentally. Lighting a fire without a lighter or matches, e.g. by using natural flint and steel with tinder, is a frequent subject of both books on survival and in survival courses. There is an emphasis placed on practicing fire-making skills before venturing into the wilderness. Producing fire under adverse conditions has been made much easier by the introduction of tools such as the solar spark lighter and the fire piston. To start a fire you’ll need some sort of heat source hot enough to start a fire, kindling, and wood. Starting a fire is really all about growing a flame without putting it out in the process. One fire starting technique involves using a black powder firearm if one is available. Proper gun safety should be used with this technique to avoid injury or death. The technique includes ramming cotton cloth or wadding down the barrel of the firearm until the cloth is against the powder charge. Next, fire the gun up in a safe direction, run and pick up the cloth that is projected out of the barrel, and then blow it into flame. It works better if you have a supply of tinder at hand so that the cloth can be placed against it to start the fire.[3] Fire is presented as a tool meeting many survival needs. The heat provided by a fire warms the body, dries wet clothes, disinfects water, and cooks food. Not to be overlooked is the psychological boost and the sense of safety and protection it gives. In the wild, fire can provide a sensation of home, a focal point, in addition to being an essential energy source. Fire may deter wild animals from interfering with a survivor, however wild animals may be attracted to the light and heat of a fire. Hydration pack manufactured by Camelbak A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.[4] A typical person will lose minimally two to maximally four liters of water per day under ordinary conditions, and more in hot, dry, or cold weather. Four to six liters of water or other liquids are generally required each day in the wilderness to avoid dehydration and to keep the body functioning properly.[5] The U.S. Army survival manual does not recommend drinking water only when thirsty, as this leads to underhydrating. Instead, water should be drunk at regular intervals.[6][7] Other groups recommend rationing water through "water discipline".[8] A lack of water causes dehydration, which may result in lethargy, headaches, dizziness, confusion, and eventually death. Even mild dehydration reduces endurance and impairs concentration, which is dangerous in a survival situation where clear thinking is essential. Dark yellow or brown urine is a diagnostic indicator of dehydration. To avoid dehydration, a high priority is typically assigned to locating a supply of drinking water and making provision to render that water as safe as possible. Recent thinking is that boiling or commercial filters are significantly safer than use of chemicals, with the exception of chlorine dioxide.[9][10][11] Culinary root tubers, fruit, edible mushrooms, edible nuts, edible beans, edible cereals or edible leaves, edible moss, edible cacti and algae can be gathered and if needed, prepared (mostly by boiling). With the exception of leaves, these foods are relatively high in calories, providing some energy to the body. Plants are some of the easiest food sources to find in the jungle, forest or desert because they are stationary and can thus be had without exerting much effort.[12] Skills and equipment (such as bows, snares and nets) are necessary to gather animal food in the wild include animal trapping, hunting, and fishing. Food, when cooked in canned packaging (e.g. baked beans) may leach chemicals from their linings [13]. Focusing on survival until rescued by presumed searchers, the Boy Scouts of America especially discourages foraging for wild foods on the grounds that the knowledge and skills needed are unlikely to be possessed by those finding themselves in a wilderness survival situation, making the risks (including use of energy) outweigh the benefits.[14] Cockroaches[15], flies [16]and ants[17] can contaminate food, making it unsafe for consumption. Celestial navigation: using the Southern Cross to navigate South without a compass Those going for trips and hikes are advised[18] by Search and Rescue Services to notify a trusted contact of their planned return time, then notify them of your return. They can tell them to contact the police for search and rescue if you have not returned by a specific time frame (e.g. 12 hours of your scheduled return time). Survival situations can often be resolved by finding a way to safety, or a more suitable location to wait for rescue. Types of navigation include: The mind and its processes are critical to survival. The will to live in a life-and-death situation often separates those that live and those that do not. Stories of heroic feats of survival by regular people with little or no training but a strong will to live are not uncommon. Among them is Juliane Koepcke, who was the sole survivor among the 93 passengers when her plane crashed in the jungle of Peru. Situations can be stressful to the level that even trained experts may be mentally affected. One should be mentally and physically tough during a disaster. To the extent that stress results from testing human limits, the benefits of learning to function under stress and determining those limits may outweigh the downside of stress.[19] There are certain strategies and mental tools that can help people cope better in a survival situation, including focusing on manageable tasks, having a Plan B available and recognizing denial.[20] In a building collapse, it is advised that you[21]: Civilian pilots attending a Survival course at RAF Kinloss learn how to construct shelter from the elements, using materials available in the woodland on the north-east edge of the aerodrome. Main article: Survival kit Often survival practitioners will carry with them a "survival kit". This consists of various items that seem necessary or useful for potential survival situations, depending on anticipated challenges and location. Supplies in a survival kit vary greatly by anticipated needs. For wilderness survival, they often contain items like a knife, water container, fire starting apparatus, first aid equipment, food obtaining devices (snare wire, fish hooks, firearms, or other,) a light, navigational aids, and signalling or communications devices. Often these items will have multiple possible uses as space and weight are often at a premium. Survival kits may be purchased from various retailers or individual components may be bought and assembled into a kit. Some survival books promote the "Universal Edibility Test".[22] Allegedly, it is possible to distinguish edible foods from toxic ones by a series of progressive exposures to skin and mouth prior to ingestion, with waiting periods and checks for symptoms. However, many experts including Ray Mears and John Kallas[23] reject this method, stating that even a small amount of some "potential foods" can cause physical discomfort, illness, or death. Many mainstream survival experts have recommended the act of drinking urine in times of dehydration and malnutrition.[citation needed] However, the United States Air Force Survival Manual (AF 64-4) instructs that this technique is a myth and should never be applied.[citation needed] Several reasons for not drinking urine include the high salt content of urine, potential contaminants, and sometimes bacteria growth, despite urine's being generally "sterile". Many classic cowboy movies, classic survival books and even some school textbooks suggest that sucking the venom out of a snake bite by mouth is an appropriate treatment and/or also for the bitten person to drink their urine after the poisonous animal bite or poisonous insect bite as a mean for the body to provide natural anti-venom. However, venom can not be sucked out and it may be dangerous for a rescuer to attempt to do so. Modern snakebite treatment involves pressure bandages and prompt medical treatment.[24] Media
