Other less obvious factors that affect the bodys use of insulin must also be taken into account. For example, some people may find that their bodies process insulin better on hot days so require less insulin. With this, the person again has to adjust their dose to the best of their understanding from their past experiences. The DAFNE regime requires the person to learn about their bodys needs through experience, which takes time and patience, but it can then become effective. Closed-loop predictive modeling
People with fluctuating insulin requirements may benefit from a closed-loop predictive modeling approach. As an extension on "carb counting", in this closed-loop predictive modeling approach, the four daily insulin dosages needed to reach the target blood sugar levels for the "normal" daily carbohydrate consumption and amount of physical activity, are continuously adjusted based on the pre-meal and pre-night blood sugar level readings. Each new blood sugar reading provides the feedback to fine-tune and track the bodys insulin requirements. Within this strategy, the key specific factors, which have to be determined experimentally, are the blood sugar correction factor and the carbohydrate ratio. The blood sugar correction factor sets both the "proportional gain" and "integral gain" factors for the four feedback loops. When taken too low, deviations from the target blood sugar level are not corrected for effectively, when taken too high, the blood sugar regulation will become unstable.
A snakebite is an injury caused by the bite of a snake, especially a venomous snake. A common sign of a bite from a venomous snake is the presence of two puncture wounds from the animals fangs. Sometimes venom injection from the bite may occur. This may result in redness, swelling, and severe pain at the area, which may take up to an hour to appear. Vomiting, blurred vision, tingling of the limbs, and sweating may result. Most bites are on the hands, arms, or legs. Fear following a bite is common with symptoms of a racing heart and feeling faint. The venom may cause bleeding, kidney failure, a severe allergic reaction, tissue death around the bite, or breathing problems. Bites may result in the loss of a limb or other chronic problems or even death.The outcome depends on the type of snake, the area of the body bitten, the amount of snake venom injected, the general health of the person bitten and whether or not anti-venom serum has been administered by a doctor in a timely manner. Problems are often more severe in children than adults, due to their smaller size. Allergic reactions to snake venom can further complicate outcomes and can include anaphylaxis, requiring additional treatment and in some cases resulting in death.Snakes bite, both as a method of hunting, and as a means of protection. Risk factors for bites include working outside with ones hands such as in farming, forestry, and construction.
