The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.
The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of “effective behavioral counseling for physical activity and diet. ”
The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups “showed significant improvements in fitness, physical activity, and diet,” with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.
Jakicic said, “the study’s findings are important because effective long-term treatments are needed to address America’s obesity. ” More information is needed, he added, to learn how to best use these devices to change “physical activity and diet behaviors” in adults who want to lose weight.

When Dylan was just seven years old, he moved to the United States with his mother, Khadine, and his twin younger brothers. The family hoped that their new home would allow them to start over and find success. However, their dream didn’t work out exactly as they imagined it would.
Life as a single mother supporting three kids is incredibly difficult, but Khadine had a particularly difficult time after her twin sons had been diagnosed with serious heart conditions. As a result, the boys suffered from dangerous symptoms and required 24-hour care. As Khadine had to work three jobs to support her family financially, it became Dylan’s responsibility to look after his young brothers. To relieve Mom’s stress, Dylan also found a part-time job at a recreation center.
While Dylan never considered his family to be a burden to him, seeing his mother and brothers become vulnerable (脆弱的) made him determined to plan his future out correctly. He believed education was the only way out of their struggle, so he made a promise to his mother that he would be the first one in the family to go to college.
For that promise, Dylan made use of each and every minute to study while taking care of his brothers. He soon became an honor student at Henry High School and took several advanced classes to keep his grades up. The College of New Jersey was his top choice. He was determined to put that admission letter in his mother’s hands.
However, weeks before Dylan’s college entrance exam, both his family and his determination were tested again when Khadine fell ill and was unable to work for a while. Soon, the bills became unmanageable and the landlord evicted (驱逐) Dylan’s family after Khadine couldn’t pay the rent. The family had no choice but to live in the shelter. The place wasn’t an ideal place to study. It was often noisy and crowded, and the lights would go out at a certain time after 11 p.m.
But Dylan continued to follow his dream.
Weeks after his application, an envelope carrying good news arrived.

个人感想 | …… |
Now, a new trial finds antiviral medications, when given soon after a child is diagnosed with type 1 diabetes (糖尿病), might help preserve those vital beta (β) cells.
Antiviral drugs could be “used alone, or as part of combination treatment, to rescue insulin (胰岛素) — producing beta cells at diagnosis of type 1 diabetes,” said a team that presented their findings at the annual meeting of the European Association for the Study of Diabetes, in Hamburg. So-called beta cells in the pancreas (胰腺) can generate insulin. But in some cases, an uncontrolled auto-immune response causes the body to attack its own beta cells, ruining a child’s capacity to produce insulin and cause type 1 diabetes. So people with type 1 diabetes rely on insulin injections to maintain healthy blood sugar levels the rest of their lives.
The researchers have been investigating the root causes of the autoimmune “malfunction” behind beta cell destruction for years, and they discovered that low-grade infections with common germs often occur in the pancreatic cells of people newly diagnosed with type l diabetes. So what if these people were given antivirals — in this case, pleconaril and ribavirin — to rid the pancreas of these infections?
The new trial, led by Dr. Mynarek, sought to answer that question. The team followed96 children aged 6 to 15 who were all diagnosed with type 1 diabetes in the study. The children were randomly selected to receive either the two antiviral medicines or a placebo (无效对照剂) for six months. Mynarek’s group tracked C-peptides levels in the blood, which “mirror the insulin production in the pancreas,” implying that the higher a child’s C-peptide levels on tests, the better their pancreas was producing insulin. According to their findings, while C-peptide levels dropped a full 24% in children who received the placebo, it fell by just 11% in those who got the antivirals. That suggests the treatment helped protect the child’s pancreatic beta cells from destruction.
The researchers concluded that “further studies should be done to evaluate whether antiviral treatment could delay the progression of beta-cell damage leading to clinical type l diabetes.”
