Summarize the following:
This once-a-day pill can greatly reduce the risk of HIV infection, but only if used as prescribed. PrEP is recommended for people who do not have HIV, but are exposed to HIV-positive sexual partners or objects regularly. Visit a doctor every 3 months when taking PrEP, to check your HIV status and monitor for renal (kidney) problems. There are no known effects of PrEP on a fetus, but there have not been many studies. Talk to your doctor if you are on PrEP and become pregnant. PrEP is only able to prevent you from contracting HIV and not other STDs. Even while taking PrEP, it is important to continue using protection while having sex. If you think you've been exposed to HIV, talk to a medical worker at an HIV clinic or hospital immediately. If you start taking PEP drugs as soon as possible, and no later than 72 hours after exposure, there is a chance that you will fight off the HIV infection. You must take the drug (or more typically two or three drugs) daily for 28 days, or as directed by the health worker. Because this is not a guaranteed method of protection, you should still be tested for HIV after the drugs are done, and a second time 3 months later. Until you test negative, tell your sexual partners that you may have HIV. If you are exposed frequently, take PrEP as a constant daily pill instead, as described above. HIV-positive people who take antiretroviral drugs can have significant success managing their infection levels. Some of these people consider this ongoing treatment an important tool to help prevent spreading the infection to their HIV-negative partners. Researchers and workers in the HIV prevention community are divided on how effective this message is. Some studies show that people who use "treatment as prevention" (TasP) are more likely to skip other forms of protection, such as condoms. While treatment can certainly reduce the risk of transmitting the infection, it is not a guarantee. Each person involved should receive regular testing to measure the risk involved. Someone infected with HIV should receive regular testing to determine the "viral load," or concentration of HIV in the bodily fluids. With constant treatment, HIV positive people can have "undetectable viral loads." It's important to understand that someone with an undetectable viral load still has HIV, and may still be able to transmit HIV to a sexual partner. While some studies show very promising results about low (or potentially nonexistent) transmission rates, more studies are needed for accurate risk assessment. Some people with undetectable viral loads in their blood may have much greater viral loads in their semen or other bodily fluids. All of the suggestions listed here are risk mitigation techniques. There is no such thing as completely safe sex or safe drug use. Things can go wrong. Accidents happen. Whether or not you use protection while having sex, you should get tested for HIV every 3 to 6 months. If you engage in any behaviors that increase your risk of contracting HIV, such as unprotected sex or sharing needles with someone, seek the advice of a medical professional as soon as you can in order to determine the best course of action.

summary: Consider Pre-Exposure Prophylaxis (PrEP) for long-term protection. Use Post-Exposure Prophylaxis (PEP) immediately after exposure. Understand treatment as prevention. Understand undetectable viral loads. Get tested regularly.

Do not use a hot comb on hair that has been chemically relaxed since it's already weakened. Grow your hair out an inch (2.5 cm) or more before you try to use a hot comb, and then only use it on the new growth. Hair should be clean and dry before you attempt to straighten it. You'll have more success with the hot comb if you've already stretched your hair out, so blow dry it as straight as possible. Separate it into sections and run a brush through it as you dry. To protect your hair from the high heat, apply some product to each section of hair before you straighten it. Purchase a special heat protectant spray at a drugstore or beauty supply store, or use a carrier oil you already have at home. Use avocado or sunflower oil since they have higher burn points than other oils. Use a regular plastic-tooth comb and make sure you can run it through your hair from root to tip without resistance before you begin. If you leave tangles in, the hot comb will snag on them and is more likely to burn your hair. Each section should only take up about half the length of the comb as well as half of its width. Depending on the size of your comb, you will probably want to make your sections one to two inches (2.5 to 5 cm) wide. Gather each section back with a hair clip or pin.

summary: Grow out your hair if it's been chemically treated. Wash and dry your hair. Apply a heat protectant to your hair. Comb all the tangles out of your hair. Separate your hair into small sections.

These may indicate pancreatic cancer, or some other ailment. Since early signs and symptoms may be ambiguous, they are often not associated with the pancreas until the disease is quite advanced. Early issues include: Moderate abdominal and/or back pain Nausea (not vomiting) Loss of appetite (food is less desirable) Unexplained significant weight loss Yellow jaundice (which also causes itchy skin) Chronic pain Severe nausea Frequent vomiting Malabsorption of food Blood glucose control problems/Diabetes (since the pancreas makes and releases insulin but becomes dysfunctional). It is not easily scanned nor viewable behind the stomach and near the small intestines. The stages are: Stage 0: Not spread. A single layer/small group of cells in the pancreas -- not yet visible on imaging tests or to the unaided eye. Stage I: Local growth. Pancreatic cancer is growing in the pancreas, Stage 1A is less than 2 centimeters (0.79in) (approx 3/4 in) across, but Stage IB is greater than 2 centimeters. Stage II: Local spread. Pancreatic cancer is larger, protruding outside the pancreas, or has spread to nearby lymph nodes. Stage III: Spread nearby. The tumor has expanded such as encasing nearby major blood vessels or nerves (unlikely to be operable, unless very limited spread) -- as well as into nearby lymph nodes -- but is not known to have metastasized to any distant organ. Stage IV: Confirmed distant spread. Pancreatic cancer has been found in distant organs such as lungs, liver, colon, etc. -- probably inoperable.
summary: Watch for subtle and nonspecific signs and symptoms: Beware that in later stages there may be: Realize that the prognosis and staging of pancreatic cancer is not easily tested.
