Baseline Exam Is Key to Eye Health
Even people with no signs or risk factors for eye disease can suffer vision loss and need to get baseline(基线)eye exams at age 40,says the American Academy of Ophthalmology(AAO)(美国眼科学会).
The reminder(提示)is part of the AAO's EyeSmart campaign to mark Save Your Vision Month in February.
“Many eye diseases progress without any warning signs,”Dr.Stephanie Marioneaux,a clin-ical correspondent for the AAO,said in a prepared statement.“Gradual changes in vision can af-fect your ability to function independently and have confidence in your abilities.”
Based on the findings from the initial screening,an eye doctor will create a schedule for follow-up eye exams.
People of any age who have symptoms of eye disease or are at high risk due to family history, diabetes(糖尿病)or high blood pressure should consult with their eye doctor to determine how often they should have their eyes checked,the AAO recommends .By 2020,43 million Americans will be at significant risk for vision loss or blindness due to age-related eye diseases such as cata-racts(白内障)and glaucoma(青光眼).That's a more than 50 percent increase over the current number of Americans with such vision-threatening diseases.
But many Americans are unconcerned about the risk of vision loss.Only 23 percent of Amer- icans are very concerned about losing their vision,while most feel weight gain or joint or back pain are greater worries than vision loss,according to an AAO survey conducted for its EyeSmart campaign.

Ebola Outbreak
1.You are likely aware that several countries in West Africa are battling an Ebola outbreak.Eb-ola is a dangerous and often lethal viral infection.Scientists believe that humans contracted the vi-rus by eating the meat of rare animals.It is now believed that bats are the primary carriers of the virus。
2.To date,there are only three major countries in West Africa experiencing a major outbreak:Si-erra Leone,Liberia and Guinea.However,other countries such as Nigeria have reported confirmed cases of Ebola with their border.
3.Unless you recently visited one of the three affected West countries,your risk of contracting the virus is virtually zero.Unlike other recent airborne virus outbreaks like SARS,the Ebola virus can only be spread through direct contact with an infected person.Specifically,Ebola is spread through contact with body fluids .Though the virus is transmittable,only an infected person exhib-iting symptoms is communicable.
4.The signs and symptoms of Ebola are non-specific and patients typically exhibit them after a week of contracting the virus.Symptoms may appear as early as two days or as late as three weeks after initial infection .Symptoms include disgust,weakness and stomach pain.More uncommon symptoms include chest pain,bleeding and sore throat.
5.Ebola is devastating because of its ability to attack and replicate in every organ of the body.This causes an overstimulation of the body's inflammatory response,causing the flu-like symptoms.The virus also causes bleeding and impairs the body's normal clotting mechanism(凝血机制), making bleeding even more severe.Loss of blood volume and decreased organ perfusion(器官灌注)ultimately lead to organ failure and death.
6.The current outbreak is the deadliest viral outbreak in over 35 years.While diseases such as the malaria(疟疾)are far more communicable,Ebola is one of the world's most fatal viral infec-tions.Ebola's fatality rate exceeds that of SARS.

Dangers Await Babies with Altitude
Women who live in the world's highest communities tend to give birth to underweight babies, a new study suggests.These babies may grow into adults with a high risk of heart disease and strokes.
Research has hinted that newborns in mountain communities are lighter than average.But it wasn't clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished—many people who live at high altitudes are relatively poor compared with those living lower down.
To find out more,Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1997 and 1998 .The babies were born in both rich and poor areas of two cities:La Paz and Santa Cruz.La Paz is the highest city in the world,at 3 .65 kilometers above sea level,while Santa Cruz is much lower,at 0 .44 kilometers.
Sure enough,Giussani found that the average birthweight of babies in La Paz was significantly lower than in Santa Cruz.This was true in both high and low-income families.Even babies born to poor families in Santa Cruz were heavier on average than babies born to wealthy families in lofty La Paz.“We were very surprised by this result,”says Giussani.
The results suggest that babies born at high altitude are deprived of oxygen before birth.
“This may trigger the release or suppression of hormones that regulate growth of the unborn child,”says Giussani.
His team also found that high-altitude babies tended to have relatively larger heads compared with their bodies.This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to the rest of the body.
Giussani wants to find out if such babies have a higher risk of disease in later life.People born in La Paz might be prone to heart trouble in adulthood,for example.Low birthweight is a risk factor for coronary heart disease.And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life.

Most Adults in U.S.Have Low Risk of Heart Disease
More than 80 percent of U .S.adults have a less than 10-percent risk of developing heart dis- ease in the next 10 years,according to a report in the Journal of the American College of Cardiolo-gy(心脏病学).Just 3 percent have a risk that exceeds 20 percent.
“I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary(心脏冠状动脉的)heart disease is distributed in the U.S.population ,” lead(带头的)author Dr.Earl S.Ford , from the Centers for Disease Control and Prevention in Atlanta,said in a statement.
The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age , who participated in the Third National Health and Nutrition(营养的供给)Examination Sur- vey from 1988 to 1994.
Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent and 3 percent had a risk above 20 percent,
The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast, race or ethnicity(种族划分)had little effect on risk distributions.
Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have a high or immediate risk,Dr.Daniel S .Berman,from Cedars-Sinai Medi- cal Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine, note in a related editorial.
Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add.

Better Control of TB Seen If a Faster Cure Is Found
The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis(结核病).Most times , the infection remains inactive(不活跃的).But each year about eight million people develop active cases of TB,usually in their lungs.Two million people die of it.The disease has increased with the spread of AIDS and drug-resist-ant forms of tuberculosis.
Current treatments take at least six months.Patients have to take a combination of several antibiotic(抗生素)drugs daily.But many people stop as soon as they feel better.Doing that can lead to an infection(传染病)that resists treatment.Public health experts agree that a faster-act-ing cure for tuberculosis would be more effective.Now a study estimates just how effective it might be .A professor of international health at Harvard University led the study.Joshua Salomon says a shorter treatment program would likely mean not just more patients cured.It would also mean fe- wer infectious patients who can pass on their infection to others.
The researchers developed a mathematical(数学的)model to examine the effects of a two-month treatment plan.They tested the model with current TB conditions in Southeast Asia.The scientists found that a two-month treatment could prevent about twenty percent of new cases.And it might prevent about twenty-five percent of TB deaths.The model shows that these reductions would take place between two thousand twelve and two thousand thirty.That is,if a faster cure is developed and in wide use by two thousand twelve.
The World Health Organization developed the DOTS program in nineteen ninety.DOTS(短期直接观察治疗)is Directly Observed Treatment, Short-course.Health workers watch tubercu- losis patients take their daily pills to make sure they continue treatment.
Earlier this year,an international partnership of organizations announced a plan to expand the DOTS program.The ten-year plan also aims to finance research into new TB drugs.The four most common drugs used now are more than forty years old.The Global Alliance for TB Drug De- velopment(全球结核病药物开发联盟)says its long-term goal is a treatment that could work in as few as ten doses.

Ants as a Barometer of Ecological Change
At picnics,ants are pests.But they have their uses.In industries such as mining,farming and forestry,they can help gauge the health of the environment by just crawling around and being antsy.
It has been recognized for decades that ant—which are highly sensitive to ecological change—can provide a near-perfect barometer of the state of an ecosystem.Only certain species, for instance,will continue to thrive at a forest site that has been cleared of trees._______(46) And still others will move in and take up residence.
By looking at which species populate a deforested area,scientists can determine how “stressed”the land is._______(47)Ants are used simply because they are so common and comprise so many species.
Where mine sites are being restored,for example,some ant species will recolonize the stripped land more quickly than others._______(48)Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recov-ery of land that it is replanting near its German Creek mine in Queensland.
Ant surveys also have been used with mine-site recovery projects in Africa and Brazil,where warm climates encourage dense and diverse ant populations.“We found it worked extremely well there,”says Jonathan Majer,a professor of environmental biology.Yet the surveys are perfectly suited to climates throughout Asia,he says,because ants are so common throughout the region.As Majer puts it:“That's the great thing about ants.”
Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting._______ (49)
Why not?Because many companies can't afford the expense or the laboratory time needed to sift results for a comprehensive survey.The cost stems,also,from the scarcity of ant specialists.______(50)
