Women who took fish oil during the last three months of pregnancy significantly lowered the risk that their children would develop asthma, a study in Denmark has found.
Among children whose mothers took fish-oil capsules, 16.9 percent had asthma by age three, compared with 23.7 percent whose mothers were given placebos. The difference, nearly 7 percentage points, translates to a risk reduction of about 31 percent.
But in the study released on Dec. 28 last year, the researchers say they are not ready to recommend that pregnant women routinely take fish oil.
Before doctors can make any recommendations, the study should be replicated, and fish oil should be tested earlier in pregnancy and at different doses.
Doctors are eager to find ways to prevent asthma, a chronic disease that causes wheezing, coughing and breathing trouble, and that sends many families to the emergency room again and again.
The incidence has more than doubled in developed countries in recent decades.
Previous research had suggested that fish oil might help prevent asthma. The idea is plausible, because inflammation in the airways and lungs plays a major role in asthma, and fatty acids in fish oil are thought to prevent inflammation. The richest sources in food include fish like herring, sardines, mackerel, eel and salmon.

It is the generation that can understand exactly how you are feeling through a few simple emoticons.
But now researchers claim that children are so engrossed in their phones, they are unable to accurately read how people are feeling in real life.
This is the result of less face-to-face time interaction, according to the study, which found young kids are glued to electronic devices for nearly five hours each day.
The finding was made after testing the ability of 11 to 12-year-olds to recognize the emotions of people pictured in photos.
“Many people are looking at the benefits of digital media in education, and not many are looking at the costs,” said study author Patricia Greenfield, professor of psychology at the Children’s Digital Media Center, part of the University of California, Los Angeles.
“Decreased sensitivity to emotional cues — losing the ability to understand the emotions of other people — is one of the costs.”
Lead author Yalda Uhls said that emoticons are a poor substitute for face-to-face communication: “We are social creatures. We need device-free time.”

Getting young children to take an hour-long nap after lunch could help them with their learning by boosting brain power, a small study suggests.
A nap appeared to help three-to-five-year-olds better remember pre-school lessons, US researchers said.
University of Massachusetts Amherst researchers studied 40 youngsters and reported their findings in Proceedings of the National Academy of Sciences. The benefit persisted in the afternoon after a nap and into the next day.
The study authors say their results suggest naps are critical for memory consolidation and early learning. When the children were allowed a siesta after lunch they performed significantly better on a visual-spatial tasks in the afternoon and the next day than when they were denied a midday snooze.

Regarding whether parents can truly comprehend what their children are thinking, psychiatrists say that with kids nowadays so enthralled with IT products, there is very little interaction and communication going on between parents and children, causing many things to remain bottled up and left unsaid. Can parents actually gain any insight by observing what video games their kids like to play? Which TV shows they enjoy watching? Which characters they like? If you want to understand a child’s inner world, there is no harm in talking and playing with them while they play with the IT products.
Lam Pok, an attending physician at Miaoli Wei Gong Memorial Hospital’s psychiatry department, says that back before 3C (computer, communications and consumer electronics) products existed, children and parents had more opportunities to talk with each other. Children used to vent their emotions by playing outdoor sports and also talked to their parents more about their feelings. With the proliferation of electronic products, video games have become the main way that children express their feelings. Characters in television dramas have also become objects for children to obtain emotional sustenance, making them less fond of talking to their parents about personal matters.
Lam says the theory of psychological projection explains why adolescents and young people often enjoy playing video games — the opponent that they are fighting is not actually the enemy in the game, but rather more likely to be someone in real life who makes them feel incredible pressure. It could be a classmate, a teacher or possibly parents. The same principle applies to watching the plots on TV or in films. Children who lack true love from their parents will easily be moved to tears when they see an alien savior come on the screen, Lam says.
When parents see their child playing video games or watching TV, it is best to get closer to them to make observations and show more concern for the child. Lam suggests that parents find an appropriate time to ask the following three questions. The first should be about which character they like the most. Liking a particular character is usually because that character has similar personality traits or has suffered in similar ways as the child. The second question should be about which character they wish they could be. This will be the person that possesses something that the child is lacking but aspires to be. The third question asks the child which character they loathe the most, which can represent someone who has probably hurt the child or gives them stress, Lam says.
It is easier for children to get sick in the spring due to highly unpredictable weather and temperatures as well as children’s lower resistance to infection. Chang Tao-tse, a pediatrician at Miaoli County’s Da Chien General Hospital, says there have been many cases of colds, bronchitis, mycoplasma pneumonia, and croup recently. He reminds parents to pay more attention when a child is not feeling well and to seek immediate medical attention.
Chang says that the common cold is the most frequently seen illness among children in the springtime. Usually a cold passes simply by drinking more water and resting, but if a high fever persists there is the possibility that it will bring about tympanitis or sinusitis. Parents and teachers should teach children to wash their hands often, avoid visiting public places, and wear masks if they do have a cold so that the virus does not continue to spread.
Also common in the spring is bronchitis, the initial symptoms of which resemble the common cold — coughing and a runny nose, but usually the patient recovers in one to two weeks. High fevers and labored breathing occur in serious cases, possibly leading to hypoxia, which requires hospitalization and is a situation that must be taken very seriously.
Chang says that mycoplasma pneumonia is often seen in school-aged children. Its initial symptoms include headaches, fever, sore throat, and lethargy. After two to five days, coughing begins, and sometimes non-respiratory symptoms such as vomiting, abdominal pains, conjunctivitis, and skin rashes also appear.
Croup occurs when a child’s voice suddenly becomes hoarse, with a “barking” cough, stridor, and breathing difficulties, during which time parents usually do not know what to do. Chang says the symptoms of croup usually appear late at night or early in the morning. Breathing warm steam can mitigate the symptoms, but it must not be taken lightly in cases of epilottitis, high fevers, short-temperedness or difficulty swallowing, or if it leads to an acute obstruction of the airways.
Other illnesses that are frequently seen in the spring include chicken pox, enterogastritis, allergic rhinitis, atopic dermatitis, and enteroviruses. Some viruses are picked up at school, so teachers must also help in protecting children’s health by letting parents know when a child is not feeling well and arranging for them to see a doctor.
