What does the HP Tablet PC offer for health care?
Tablet PCs allow health care professionals of all levels to be more efficient and accurate in their day-to-day activities by enhancing their ability to perform a variety of tasks, both at their desks or on the go.

Examples of activities that can be improved include:

• Collection and Integration of Patient Data
• Patient Record Retrieval, Review and Collaboration,
• Meetings
• House calls and patient bedside visits
• Wireless interaction among staff and physicians

These activities all involve basic tasks, which are made easier by the HP Tablet PC. Some examples are:

• Completing electronic forms or “writing” prescriptions
• Taking progress notes in handwriting that can be converted to printed text
• Adding handwritten notes to charts and images
• Integrating several reports, such as tests and treatment plans, into one document
• Sharing data via a secure wireless LAN

KNOWING THE BASICS
Physical fitness is most easily understood by examining its components, or “parts.” There is widespread agreement that these four components are basic:

• Cardiorespiratory Endurance – the ability to deliver oxygen and nutrients to tissues, and to remove wastes, over sustained periods of time. Long runs and swims are among the methods employed in measuring this component.
• Muscular Strength – the ability of a muscle to exert force for a brief period of time. Upper-body strength, for example, can be measured by various weight-lifting exercises.
• Muscular Endurance – the ability of a muscle, or a group of muscles, to sustain repeated contractions or to continue applying force against a fixed object. Pushups are often used to test endurance of arm and shoulder muscles.
• Flexibility – the ability to move joints and use muscles through their full range of motion. The sit-andreach test is a good measure of flexibility of the lower back and backs of the upper legs.

Why do we need vitamin D?
In 1919, Sir Edward Mellanby discovered vitamin D and the role it plays in the development of the childhood bone disease, rickets. Since then, vitamin D has been recognized for its role in enhancing calcium absorption, thereby promoting good bone health. In fact, vitamin D deficiency can also lead to osteomalacia—weak bones in adults. But, new research is suggesting various other roles for vitamin D as well. Adequate vitamin D levels are thought to reduce risk of breast, colon and prostate cancers and play a preventative role in multiple sclerosis, diabetes and rheumatoid arthritis. Finally, emerging research suggests that vitamin D may be involved in optimal functioning of the immune system, mental activities and in reducing risk of periodontal disease—a chronic inflammatory gum disease that can lead to tooth loss.

Prevention – Linus Pauling believed that chronic scurvy might be prevented with a daily intake of of vitamin C as low as 3000 mg. This amount approximates what some animals synthesize under normal conditions. Dr. Sydney Bush’s Cardioretinometry (microscopic pictures of the retina) suggests that some people require up to 10,000 mg daily for prevention.

Populations at risk for, and consequences of, vitamin B12 deficiency

Vegetarians
Because plants do not synthesize vitamin B12, individuals who consume diets completely free of animal products (vegan diets) are at risk of vitamin B12 deficiency. This is not true of lacto-ovo vegetarians, who consume the vitamin in eggs, milk, and other dairy products.

How much calcium and vitamin D do you need?

Calcium
Dairy products are a good source of calcium. There are also small amounts in other foods including breads, cereals, fruits and vegetables, fish with edible bones (e.g. tinned salmon and sardines), tahini, almonds, figs and foods fortified with calcium. If you find it difficult to get enough calcium from food ask your doctor or dietitian about taking a calcium supplement.

If you can’t tolerate dairy products or don’t enjoy them, there are some calciumenriched products available such as calcium-enriched orange juice, cereals and soy milk. However calcium added to soy drinks may not be as well absorbed as from dairy foods, so you may need larger servings of soy drinks.

People need different amounts of calcium at different ages – the food table at the end of this fact sheet shows you how to get calcium from food.
