Omega-3 fatty acids include alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). Your body needs omega-3s; they appear in the membranes that surround every cell in your body. Some people take omega-3 supplements such as cod liver oil, but with a little dietary care, you should be able to obtain adequate omega-3s from your daily nutrition. ALA is available in plant-based oils, especially flaxseed and canola oils. Some leafy greens, wheat germ, and walnuts also contain ALA. DHA and EPA occur naturally in fatty fish such as tuna, mackerel, sardines, bluefish, and salmon. Vegetarians may obtain some DHA and EPA from algal sources.
The positive effects on health of a diet rich in omega-3s are clear, although further research is needed to know exactly how omega-3s help. They seem to reduce inflammation, lower blood pressure, and reduce the buildup of plaque in the arteries, making them critical in maintaining heart health. Researchers have found that people with a high omega-3 intake seem to have fewer colon and breast cancers. Because of the fatty acids’ effect on inflammation, some doctors find omega-3 supplements useful for asthma and arthritis patients.
Less clear are the effects on mental health, although there are health professionals who believe strongly that high levels of omega-3s can reduce depression, improve memory, and moderate symptoms of attention deficit hyperactive disorder. Until more research takes place, it is unwise to rely on omega-3s to cure mental health issues. However, ensuring that your diet contains ample amounts of these critical fatty acids is still a good idea.

Most nail abnormalities are innocuous, but some may be clues to underlying health problems. Everyone should be alert to changes in the color, shape, or texture of his or her nails. Nails may provide an early warning sign to serious illness. White nails may indicate liver problems, especially when they are accompanied by yellowish skin on the fingers.
Yellow nails, on the other hand, usually just mean you have a treatable fungal infection. Pale nails can be a sign of anemia, whereas blue nails usually mean a lack of oxygen due to a lung or heart problem. If your usually smooth nails become pitted, this could be a sign of rheumatoid or psoriatic arthritis. If they are indented and soft, you may have a serious iron deficiency. If normally healthy nails suddenly crack and split, you may need to get your thyroid checked. Dark lines under the nail may indicate the deadly skin cancer, melanoma.
Any unusual changes in your nails should lead you to make an appointment with your general practitioner or with a dermatologist. Your nails may be trying to tell you something about what’s going on in the rest of your body.

SOPHIA:
In a student union at the University of Michigan is a conference room named the Sophia B. Jones Room. The woman for whom it is named came from a family of impressive activists and revolutionaries and went on to have a remarkable career in medicine and education. Sophia was born in 1857 in Chatham, Ontario, Canada. Her father was one of the first Black graduates of Oberlin College in Ohio and was a strong abolitionist. Sophia had an older sister, Anna, and a younger sister, Fredericka. Both became teachers, and Anna was a suffragist who later helped create the National Association of Colored Women’s Clubs.
Sophia took a different path; she started at the University of Toronto, but dissatisfied with the medical education afforded to women there, she moved to Michigan and graduated in 1885 as the university’s first Black female doctor of medicine. She was quickly hired by the historically Black women’s school of higher learning, Spelman College, to create a nursing program, thus becoming Spelman’s first Black faculty member.
Following her work at Spelman, Sophia moved on to Wilberforce University in Ohio, a school that was the first to be owned and run by African-Americans, and one at which W. E. B. Du Bois had been an esteemed professor. She continued to believe and teach that education was the path to public health. She worked in hospitals in Philadelphia, St. Louis, and Kansas City until her retirement, at which time she and her sister Anna moved to California. A society named for Sophia continues to provide medical students and alumni at Spelman with scholarships and financial support. In this way, Spelman maintains Sophia’s inspiring goals of educating health workers and improving public health.

According to the Centers for Disease Control and Prevention (CDC), tickborne diseases doubled in the United States between the years 2004 and 2016. Lyme disease, in particular, is difficult to diagnose due to its disparate symptoms that mimic other diseases, making it greatly underreported. As a result, the prevalence of Lyme disease is thought to be even higher than the CDC suggests.
Lyme disease is caused by the bacterium Borrelia burgdorferi, which is spread through a relationship involving three animals. This relationship starts with the white-footed mouse (or in California, the Western gray squirrel), which is prone to infection by the bacterium. Ticks in their larval form feed on the blood of these mice. If the mouse is infected, the tick becomes infected as well. After passing through a dormant phase, the tick nymph, usually the size of a poppy seed, seeks another blood meal. This meal might come from another mouse, a human, or a dog or cat.
The nymphs then molt into active adults, whose primary food source is the whitetail deer. They mate on the deer, drop off, and lay their eggs, thus starting the cycle over again. Humans can be bitten by either an infected nymph or a full-grown adult tick. For Lyme disease transmission, the tick needs to attach for about 36 hours. Unfortunately, tick bites are easy to overlook; they do not itch like mosquito bites or sting like deerfly bites. Many people go without treatment for months until a test clarifies their seemingly unrelated symptoms, which may include joint pain, a rash, fatigue, swollen glands, chills or fever, headache, or even paralysis.
If you know you have been bitten by a tick, time is of the essence. It is important to see a doctor, get tested, and receive treatment promptly.

What is the meaning of the word disparate as used in the first paragraph?

• A. Unusual
• B. Diverse
• C. Trivial
• D. Damaging

Gout is a form of arthritis that typically comes on suddenly, causing intense joint pain, especially in the feet, ankles, wrists, or fingers. It is caused by the accumulation of urate crystals in the joint. Whereas normally, uric acid dissolves in the bloodstream and passes out of the body in the urine, at times, uric acid builds up, forming crystals. A diet rich in the foods that increase levels of uric acid—meat, seafood, fructose—may be a risk factor for gout.
It now appears that nurse-led treatments focusing on lifestyle may provide significant aid for gout patients. Medical treatment for gout has usually involved pain relievers and corticosteroids. In addition, doctors may prescribe uric acid inhibitors for patients who have recurrent gout attacks. A recent British study indicates that nurse-led care, which includes holistic education, lifestyle advice, and some form of urate-lowering therapy, is not only cheaper but also more successful than the usual physician-led treatment. Nurses were thoroughly trained in the causes and management of gout and were encouraged to include patients in decisions involving their own treatment. After two years, outcomes largely favored the nurse-led patients.

Which is the best title for this passage?

• A. "Medical Treatment for Gout"
• B. "Uric Acid Affects the Joints"
• C. "Risk Factors for One Type of Arthritis"
• D. "Nurse-Led Care Aids Gout Patients"
