FRUITS & VEGETABLE


Keep Fruits & Veggies on the Table
No matter the emphasis on protein, make sure you leave room for fruits and vegetables in a high-protein diet. These nutrient gold mines contain powerful antioxidants that aren't found in most other foods, and research suggests that people who eat plenty of fruits and veggies may lower their risk of cancer.

ENERGY BARS


Cereal and Energy Bars
Pressed for time? You can turn to high-protein cereal or energy bars to give your high-protein diet a fast boost. Just make sure the bars you choose have at least 6 grams of protein and not too much sugar or fat.

LOW FAT MILK PRODUCTS


Low-Fat Milk Products
If you want to give your high-protein diet a tasty boost, don’t overlook dairy products as a protein source. Milk, cheese, and yogurt are not only protein-rich, they also provide calcium for strong bones and a healthy heart. Strive for 2-4 servings of low-fat or nonfat milk products daily.

EGGS


Eggs: Affordable, Convenient, & Tasty
Eggs are perhaps the most classic and certainly least expensive form of protein. The American Heart Association says an egg a day is safe for healthy adults, so you may want to get cracking with eggs when you’re on a high-protein diet.

DIET


The Goal Is Weight Loss
High-protein diets take a page from the low-carb craze. The goal is to lose weight by eating more protein-packed foods, which often means consuming fewer carbohydrates. The portion of total calories derived from protein is what defines a high-protein diet. In a typical diet 10%-15% of daily calories come from protein. In a high-protein diet, this number can be as high as 30%-50%.Curbing Appetite Plays One Role
Besides curbing appetites, high-protein diets may also change a person’s metabolism. When carbohydrates are severely restricted, the body begins burning its own fat for fuel – a state called ketosis. Ketosis may shed weight, but it’s also associated with headaches, irritability, nausea, kidney trouble, and heart palpitations.Starting a High-Protein Diet
High-protein diets come in many forms, and not all are created equal. The most nutritious high-protein plans are low in fat and moderate in carbohydrates, rather than high in fat and low in carbohydrates. The following slides present a variety of foods that fit the high-protein diet bill.

Human Immunodeficiency Virus( HIV )


HIV is present to variable degrees in the blood and genital secretions of virtually all individuals infected with HIV, regardless of whether or not they have symptoms. The spread of HIV can occur when these secretions come in contact with tissues such as those lining the vagina, anal area, mouth, or eyes (the mucus membranes), or with a break in the skin, such as from a cut or puncture by a needle. The most common ways in which HIV is spreading throughout the world include sexual contact, sharing needles, and by transmission from infected mothers to their newborns during pregnancy, labor (the delivery process), or breastfeeding. (See the section below on treatment during pregnancy for a discussion on reducing the risk of transmission to the newborn.)
Sexual transmission of HIV has been described from men to men, men to women, women to men, and women to women through vaginal, anal, and oral sex. The best way to avoid sexual transmission is abstinence from sex until it is certain that both partners in a monogamous relationship are not HIV-infected. Because the HIV antibody test can take up to six months to turn positive after infection occurs, both partners would need to test negative six months after their last potential exposure to HIV. If abstinence is out of the question, the next best method is the use of latex barriers. This involves placing a condom on the penis as soon as an erection is achieved in order to avoid exposure to pre-ejaculatory and ejaculatory fluids that contain infectious HIV. For oral sex, condoms should be used for fellatio (oral contact with the penis) and latex barriers (dental dams) for cunnilingus (oral contact with the vaginal area). A dental dam is any piece of latex that prevents vaginal secretions from coming in direct contact with the mouth. Although such dams occasionally can be purchased, they are most often created by cutting a square piece of latex from a condom.

Early Pregnancy Symptoms


Most women equate a missed menstrual period with the possibility of being pregnant, but other symptoms and signs are experienced by most women in the early stages of pregnancy. It's important to remember that not all women will experience all of these symptoms or have the symptoms to the same degree. Even the same woman can have different types of symptoms in a subsequent pregnancy than she had in previous pregnancies. The following are the most common pregnancy symptoms in the first trimester.

Missed period
A missed menstrual period is most often the first sign of pregnancy. Sometimes a woman who is pregnant may still experience some bleeding or spotting around the time of the expected period, typically 6 to 12 days after conception. When it occurs, this so-called "implantation bleeding" is generally not as heavy or long as a regular menstrual period. This small amount of bleeding that occurs at the time of the expected menstrual period happens when the fertilized egg attaches to the uterine wall and is referred to as implantation bleeding.
Any bleeding during pregnancy is typically lighter than that observed during the regular menstrual period. However, if a woman does not have regular menstrual cycles, she may notice some of the other symptoms of early pregnancy before it is apparent that the menstrual period has been missed. A missed menstrual period also does not confirm that a woman is pregnant even if she has regular cycles, since both emotional and physical conditions may cause absent or delayed periods.

Introduction to breast cancer


Breast cancer is the most common cause of cancer in women and the second most common cause of cancer death in women in the U.S. While the majority of new breast cancers are diagnosed as a result of an abnormality seen on a mammogram, a lump or change in consistency of the breast tissue can also be a warning sign of the disease. Heightened awareness of breast cancer risk in the past decades has led to an increase in the number of women undergoing mammography for screening, leading to detection of cancers in earlier stages and a resultant improvement in survival rates. Still, breast cancer is the most common cause of death in women between the ages of 45 and 55. Although breast cancer in women is a common form of cancer, male breast cancer does occur and accounts for about 1% of all cancer deaths in men.
Research has yielded much information about the causes of breast cancers, and it is now believed that genetic and/or hormonal factors are the primary risk factors for breast cancer. Staging systems have been developed to allow doctors to characterize the extent to which a particular cancer has spread and to make decisions concerning treatment options. Breast cancer treatment depends upon many factors, including thee type of cancer and the extent to which it has spread. Treatment options for breast cancer may involve surgery (removal of the cancer alone or, in some cases, mastectomy), radiation therapy, hormonal therapy, and/or chemotherapy.

Cigarettes May Contain Bacteria


Nov. 24, 2009 -- Cigarettes are massive germ factories that may expose users and passersby to a swarm of disease-causing bacteria, a study shows.
It's well known that cigarette smoke harbors hundreds of toxic chemicals that are bad for your health. But a University of Maryland environmental health researcher says that's not the only danger. DNA examination of four cigarette brands shows, for the first time, that cigarettes are "widely contaminated" with hundreds of different types of bacteria. In fact, there appears to be as many bacteria in cigarettes as there are chemicals.
"The commercially available cigarettes that we tested were chock full of bacteria, as we had hypothesized, but we didn't think we'd find so many that are infectious in humans," says researcher Amy R. Sapkota, an assistant professor in the University of Maryland's School of Public Health.
Sapkota and microbial ecologists at the Ecole Centrale de Lyon in France examined the bacteria content in four major cigarette brands: Camel, Kool Filter Kings, Lucky Strike Original Red, and Marlboro Red and found similar types of bacteria in each one.
Previous research has watched for bacterial growth in lab dishes containing small tobacco samples, but this study is the first to scrutinize a cigarette's bacterial genetic makeup.

How Much Will the H1N1 Swine Flu Vaccine Cost?


The U.S. government purchased the vaccine from manufacturers and is providing the vaccine at no cost. The CDC has asked providers NOT to charge for administering the vaccine. Even if they do, several large insurance companies have said the costs would be covered. On October 24, 2009, President Barack Obama declared the H1N1 swine flu a national emergency.

What are swine flu symptoms?


Symptoms of swine flu are like regular flu symptoms and include fever, cough, sore throat, body aches, headache, chills, and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. Those symptoms can also be caused by many other conditions, and that means that you and your doctor can't know, just based on your symptoms, if you've got swine flu. It takes a lab test to tell whether it's swine flu or some other condition.

What Types of Swine Flu Vaccines Are Being Produced?


There are two forms of 2009 H1N1 vaccines being produced: a 2009 H1N1 "flu shot" and the 2009 H1N1 nasal spray flu vaccine. The same manufacturers who produce seasonal flu vaccines are producing 2009 H1N1 vaccines for use in the United States, and the vaccines are being made in the same way that the seasonal vaccines are made.

15 ways of food safety


1. Consider your source. Eating locally grown food is becoming more popular, but that doesn't necessarily mean it's safer than supermarket produce.
"Just because you grow it in a farm down the street, it doesn't make it any safer or worse than any other produce that you get," Suresh Pillai, PhD, tells WebMD.
Pillai is a professor of food safety and environmental microbiology at Texas A&M University.
Locally grown food "is pretty much on par with what you would find in a supermarket," in terms of food safety, Demma agrees. "Of course, there [are] other reasons to buy and eat locally," she says.
At farmers markets, you may get the chance to meet and talk with the people who produced your food.
Farmers markets have become more common, with 4,385 U.S. farmers markets in 2006, up from 1,755 farmers markets in 1994, according to the U.S. Department of Agriculture (USDA).
Eating food shipped from overseas? The melamine-tainted animal feed ingredients came from China. But that doesn't mean that all imported food is suspect.
"The assumption that the imported products are unsafe is absolutely not true," Pillai says. "In fact, there are as many outbreaks associated with foods grown in the United States. So blaming it on imported products, I think, is a cop-out."
2. Map your supermarket route. Don't cruise the store aisles aimlessly. Gather nonperishable items first, fresh or frozen goods last. That strategy minimizes the time that perishable goods sit in your shopping cart instead of in a freezer or refrigerator.
3. Be choosy. Select fresh produce that isn't bruised or damaged. Check that eggs aren't cracked. Look for a clean meat or fish counter and a clean salad bar. Don't buy bulging or dented cans, cracked jars, or jars with loose or bulging lids. If fresh-cut produce (such as half a watermelon or bagged salad mixes) is on your shopping list, choose those that are refrigerated or surrounded by ice.
4. Pack it up. At the grocery store, bag fresh fruits and vegetables separately from meat, poultry, and seafood products.
Bring an ice chest to keep frozen or perishable items if it will take more than an hour to get those items home.
No ice chest? If it's hot outside, put the groceries in the air-conditioned passenger area of your car instead of putting them in the trunk, which may not have air-conditioning.
5. Keep your kitchen clean. Wash your cutting boards, countertops, refrigerator, pots, and utensils regularly in hot, soapy water, especially after they've been in contact with raw meat, poultry, and seafood.
6. Check your cutting boards. They shouldn't have lots of cracks and crevices where bacteria can lurk.
7. Sanitize. The FDA recommends periodically sanitizing your cutting boards, countertops, and kitchen sink drain with a homemade mixture of one teaspoon of chlorine bleach to one quart of water.
Sponges and dishcloths can house bacteria, so wash them weekly in hot water in the washing machine.
8. Store your food properly. Refrigerate frozen and perishable items as soon as possible.
Don't store foods near household chemicals or cleaning products. Some produce -- like onions and potatoes -- don't need to go in the refrigerator, but don't store them under the sink, where they could be damaged by leaky pipes.
9. Check the refrigerator and freezer temperature. Set the refrigerator temperature to 40 degrees Fahrenheit, set the freezer to zero degrees Fahrenheit.
Use a refrigerator thermometer to check those temperatures periodically.
10. Wash your hands. Before you handle food, lather up with soap and hot water, washing your hands for at least 20 seconds. Repeat after handling produce, meat, poultry, seafood, or eggs.
11. Wash fruits and vegetables in running water. A small scrub brush may help, but don't use soap or other detergents to wash produce.
What about produce washes? "All of these solutions and washes may have some applications but studies show that washing with water is as safe as anything else," says Pillai, who calls water the "most effective, the safest, and the cheapest" way to wash produce.
12. Thaw foods in the refrigerator, not on the countertop. It may take longer, but it's safer.
13. Cook foods thoroughly. Use a meat thermometer to make sure meat is fully cooked. Never put cooked meats on an unwashed plate or platter that has held raw meat.
14. Store leftovers safely. Refrigerate leftovers in tight containers as soon as possible and use them within three days. When in doubt, throw it out.
15. Maintain perspective. "There's no such thing as a zero risk," says Pillai. "There's no such thing as a sterile product."

NUTRITIONS TIPS


Green Beans (Available all year) Nutrition Tip: One cup of raw snap green beans contains 4 grams of fiber (a combination of soluble and insoluble); 11% of the recommended daily amount of folic acid, vitamin A and vitamin B2; and 24% of the recommended daily amount of vitamin C. Storage Tip: Refrigerate green beans, unwashed, in a plastic bag for up to four days. Prep Tip: Snap or cut off the ends, cut longer beans crosswise into the length desired, and rinse before cooking. Cooking Tip: Green beans are most often cooked by microwaving, steaming, stir-frying, or boiling. The key is to cook only until tender-crisp. If stir-frying, cut the beans in 1-inch pieces so they will cook quickly along with the other ingredients.
Guava (September-March) Nutrition Tip: One guava contains 5 grams of fiber (a combination of soluble and insoluble), and 10% of the recommended daily amount of vitamin A, Vitamin B6, and 220% of the recommended daily amount of vitamin C. Storage Tip: Ripen at room temperature, if needed. You can store guavas at room temperature for up to one week, or refrigerate for up to two weeks. Prep Tip: Guavas have sturdy skin, so you can cut them in half and scoop out the semi-soft inside flesh with a teaspoon (discard the shell). They're ready to eat when the fruit gives slightly to gentle pressure. Cooking Tip: Use uncooked guavas in recipes in place of strawberries and kiwi. Use them cooked in pies, breads, or preserves, or cold or hot in sauces, juices, or sorbets.
Kiwi (October-March) Nutrition Tip: One kiwi contains 3 grams of fiber (mostly the insoluble type), and 76% of the recommended daily amount for vitamin C. Storage Tip: They're ready to eat when they give slightly to gentle pressure. Really soft kiwi fruit is too ripe to eat. Ripen at room temperature, or refrigerate in the crisper drawer for three to five days. Prep Tip: The skin on kiwi fruit can be eaten if desired. But if you want to peel them, cut in slices and then peel; use a paring knife to cut off the ends and then remove the skin; or cut in half and scoop out the flesh with a spoon. Cooking Tip: Kiwi is usually enjoyed raw. Pureed kiwi can be used to make all types of sorbet or margaritas. Kiwi is a beautiful addition to desserts and salads.

Asthma


Asthma is a breathing problem that results from the inflammation and spasm of the lung's air passages (bronchial tubes). The inflammation causes a narrowing of the air passages, which limits the flow of air into and out of the lungs. Asthma is most often, but not always, related to allergies. Common symptoms include:

Wheezing
Coughing
Chest tightness

What causes allergies?


To help answer this question, let's look at a common household example. A few months after the new cat arrives in the house, dad begins to have itchy eyes and episodes of sneezing. One of the three children develops coughing and wheezing, especially when the cat comes into her bedroom. The mom and the other two children experience no reaction whatsoever to the presence of the cat. How can we explain this?
The immune system is the body's organized defense mechanism against foreign invaders, particularly infections. Its job is to recognize and react to these foreign substances, which are called antigens. Antigens are substances that are capable of causing the production of antibodies. Antigens may or may not lead to an allergic reaction. Allergens are certain antigens that cause an allergic reaction.

What does an allergy mean?


An allergy refers to an exaggerated reaction by our immune system in response to bodily contact with certain foreign substances. It is exaggerated because these foreign substances are usually seen by the body as harmless and no response occurs in non- allergic people. Allergic people's bodies recognize the foreign substance and one part of the immune system is turned on. Allergy-producing substances are called "allergens." Examples of allergens include pollens, dust mitedanders, and foods. To understand the language of allergy it is important to remember that allergens are substances that are foreign to the body and can cause an allergic reaction in certain people.
When an allergen comes in contact with the body, it causes the immune system to develop an allergic reaction in persons who are allergic to it. When you inappropriately react to allergens that are normally harmless to other people, you are having an allergic reaction and can be referred to as allergic or atopic. Therefore, people who are prone to allergies are said to be allergic or "atopic."

The Role of Domain Knowledge in Automating Medical Text Report Classification


Objective: To analyze the effect of expert knowledge on the inductive learning process in creating classifiers for medical text reports.
Design: The authors converted medical text reports to a structured form through natural language processing. They then inductively created classifiers for medical text reports using varying degrees and types of expert knowledge and different inductive learning algorithms. The authors measured performance of the different classifiers as well as the costs to induce classifiers and acquire expert knowledge.
Measurements: The measurements used were classifier performance, training-set size efficiency, and classifier creation cost.
Results: Expert knowledge was shown to be the most significant factor affecting inductive learning performance, outweighing differences in learning algorithms. The use of expert knowledge can affect comparisons between learning algorithms. This expert knowledge may be obtained and represented separately as knowledge about the clinical task or about the data representation used. The benefit of the expert knowledge is more than that of inductive learning itself, with less cost to obtain.
Conclusion: For medical text report classification, expert knowledge acquisition is more significant to performance and more cost-effective to obtain than knowledge discovery. Building classifiers should therefore focus more on acquiring knowledge from experts than trying to learn this knowledge inductively.
