Osteoporosis reduces the density and quality of bone, greatly increasing the risk of fracture. Many people (especially older people) are unaware they have osteoporosis and are at risk of fragility fractures.
The calculator was developed using data collected in the Dubbo Osteoporosis Epidemiology Study, conducted by our Bone Biology Lab . The study, begun in 1989, includes data from more than 2,500 men and women aged 60+.
Objective: This study aimed to develop a machine learning-based web calculator that can provide an accurate assessment of the likelihood of early death among patients with bone metastasis.
Methods: This study analyzed a large cohort of 118,227 patients diagnosed with bone metastasis between 2010 and 2019 using the data obtained from a national cancer database. The entire cohort of patients was randomly split 9:1 into a training group (n=106,492) and a validation group (n=11,735). Six approaches-logistic regression, extreme gradient boosting machine, decision tree, random forest, neural network, and gradient boosting machine-were implemented in this study. The performance of these approaches was evaluated using 11 measures, and each approach was ranked based on its performance in each measure. Patients (n=332) from a teaching hospital were used as the external validation group, and external validation was performed using the optimal model.
Results: In the entire cohort, a substantial proportion of patients (43,305/118,227, 36.63%) experienced early death. Among the different approaches evaluated, the gradient boosting machine exhibited the highest score of prediction performance (54 points), followed by the neural network (52 points) and extreme gradient boosting machine (50 points). The gradient boosting machine demonstrated a favorable discrimination ability, with an area under the curve of 0.858 (95% CI 0.851-0.865). In addition, the calibration slope was 1.02, and the intercept-in-large value was -0.02, indicating good calibration of the model. Patients were divided into 2 risk groups using a threshold of 37% based on the gradient boosting machine. Patients in the high-risk group (3105/4315, 71.96%) were found to be 4.5 times more likely to experience early death compared with those in the low-risk group (1159/7420, 15.62%). External validation of the model demonstrated a high area under the curve of 0.847 (95% CI 0.798-0.895), indicating its robust performance. The model developed by the gradient boosting machine has been deployed on the internet as a calculator.
Conclusions: This study develops a machine learning-based calculator to assess the probability of early death among patients with bone metastasis. The calculator has the potential to guide clinical decision-making and improve the care of patients with bone metastasis by identifying those at a higher risk of early death.
The Lean Body Mass Calculator computes a person's estimated lean body mass (LBM) based on body weight, height, gender, and age. For comparison purposes, the calculator provides the results of multiple formulas.
Lean body mass (LBM) is a part of body composition that is defined as the difference between total body weight and body fat weight. This means that it counts the mass of all organs except body fat, including bones, muscles, blood, skin, and everything else. While the percentage of LBM is usually not computed, it on average ranges between 60-90% of total body weight. Generally, men have a higher proportion of LBM than women do. The dosages of some anesthetic agents, particularly water-soluble drugs, are routinely based on the LBM. Some medical exams also use the LBM values. For body fitness and routine daily life, people normally care more about body fat percentage than LBM. To compute body fat, consider using our body fat calculator or ideal weight calculator.
Lean body mass includes the combined mass of bones, muscles, water, ligaments, tendons, and internal organs. Internal organs include some essential fat and the mass of this fat is included within the measurement of lean body mass. Although internal organs also have surrounding subcutaneous fat, this fat is not included within the measurement of lean body mass.
We recommend you always aim to get all the calcium you need as part of a healthy, balanced diet. To see whether you're getting enough calcium from what you eat and drink, you can use this online calcium calculator, from the University of Edinburgh.
This ideal weight calculator is designed for healthy adult women and its purpose is to serve as a motivation to help you achieve your goals. Knowing your ideal weight is the first step in any weight loss journey and having a real goal helps you stay focused and motivated.
To choose your goal BMI, required for the ideal weight calculator, you need to take into account your bone structure. Larger bones are heavier and therefore you should aim for a BMI closer to 24.9. If you have a small body frame, your goal BMI should be closer to 18.5.
IDEAL WEIGHT vs CURRENT WEIGHT Is your pet at their ideal weight? We recommend using the calculator at your pets current weight and also try it at their ideal weight. This way you know what to work towards, but rapidly decreasing or increasing food is not advised. Work towards goals over time.
BREED As a general rule our calculator calls a pet an adult at 12 months. Some larger breeds are growing while past the 12 month marker and have not reached 'adulthood.' The same vice versa where some 'miniature' breeds have very little growing to do after 8 months. These are factors that can play into feeding amounts. If you are unsure about any change to feeding amounts we recommend calling one of our store associates for a much more detailed evaluation.
CALORIC NEEDS Just like humans, your pet has caloric intake requirements. Our feeding calculator is a generic calculator as it does not take into effect specifically what you are feeding. Feeding calculators going by percentages are assuming a raw diet that is balanced over time through variety. If variety is not attainable or your pet has specific dietary needs, we recommend speaking to one of our store associates so we can better evaluate feeding amounts based on the caloric intake of the specific foods you are feeding.
KITTENS It is typically recommended to allow a kitten to eat as much as they want. If you've used our calculator and find your kitten is showing signs of wanting more, offer a little more.
The Bone burial calculator is a calculator that can be used to efficiently train Prayer. This particular skill is noted for being something that can be "purchased", and none of this activity is "profitable" in terms of purchasing the bones from the Grand Exchange or from another player. Many of these bones sell in large enough quantities that the prices change on a daily basis.
The Chaos Altar calculations are an approximation. The Chaos Altar provides Prayer XP per bone equal to the Gilded Altar, however it has a 50% chance to not consume the bone when offered. This results in an average increase of 100% XP, which when multiplied with the experience multiplier of 3.5 the Chaos Altar results in an average of 700% experience per bone.
To calculate the cooking time for a bone-in turkey breast, multiply the weight of the turkey breast by the rate of cooking. Then, add the adjustment time for oven preheating and resting the turkey after cooking.
Napier's bones is a manually-operated calculating device created by John Napier of Merchiston, Scotland for the calculation of products and quotients of numbers. The method was based on lattice multiplication, and also called rabdology, a word invented by Napier. Napier published his version in 1617.[1] It was printed in Edinburgh and dedicated to his patron Alexander Seton.
Using the multiplication tables embedded in the rods, multiplication can be reduced to addition operations and division to subtractions. Advanced use of the rods can extract square roots. Napier's bones are not the same as logarithms, with which Napier's name is also associated, but are based on dissected multiplication tables.
The complete device usually includes a base board with a rim; the user places Napier's rods and the rim to conduct multiplication or division. The board's left edge is divided into nine squares, holding the numbers 1 to 9. In Napier's original design, the rods are made of metal, wood or ivory and have a square cross-section. Each rod is engraved with a multiplication table on each of the four faces. In some later designs, the rods are flat and have two tables or only one engraved on them, and made of plastic or heavy cardboard. A set of such bones might be enclosed in a carrying case.
The left-most column, preceding the bones shown coloured, may represent the 1 bone. (A blank space or zero to the upper left of each digit, separated by a diagonal line, should be understood, since 1 1 = 01, 1 2 = 02, 1 x 3 = 03, etc.) A small number is chosen, usually 2 through 9, by which to multiply the large number. In this example the small number by which to multiply the larger is 6. The horizontal row in which this number stands is the only row needed to perform the remaining calculations and may now be viewed in isolation.
For the calculation, the digits separated by vertical lines (i.e. paired between diagonal lines, crossing over from one bone to the next) are added together to form the digits of the product. The final (right-most) number on that row will never require addition, as it is always isolated by the last diagonal line, and will always be the final digit of the product. In this example, there are four digits, since there are four groups of bone values lying between diagonal lines. The product's digits will stand in the order as calculated left to right. Apart from the first and the final digit, the product's digits will each be the sum of two values taken from two different bones.
