Health Tip: Help Your Child Prepare for a Sibling (HealthDay)

(HealthDay News) -- It's common for children to feel jealous of a new sibling, including acting out and misbehaving.

The Nemours Foundation offers these suggestions for easing your child's transition to being an older sibling:

  • Let your child help choose items for the new baby's bedroom, or a special gift to share with the baby.
  • Spend some quality alone time with the elder child.
  • Read books, role-play and talk about what it's like with a new baby in the house.
  • Play up your child's new role as the "big" brother or sister.
  • Take your child with you to either an ultrasound appointment or to visit the new baby at the hospital.
  • Keep your child as involved as possible in preparing for the new baby.

NYC recommends AIDS drugs for any person with HIV

(AP) ? New York City health officials said Thursday they are recommending that any person with HIV be offered AIDS drugs as soon as they are diagnosed with the virus, an aggressive move that has been shown to prolong life and stem the spread of the disease.

Standard practice has been to have patients put off the expensive pill regimen ? which can cost up to $15,000 a year in the United States ? until the immune system weakens.

But city Health Commissioner Thomas Farley said recent studies have shown that the benefits of early treatment, combined with education and testing, appears to be a promising strategy for countering the epidemic.

"I'm more optimistic now than I've ever been about this epidemic that we can drive our new rates down to zero or close to it ? eventually. I don't know how soon," Farley said in an interview Wednesday.

More than 110,000 people in New York City are infected with HIV, more than in any other U.S. city. San Francisco, which had more than 18,000 people living with HIV, made a similar recommendation in 2010.

New York City health officials said the new recommendation could initially help about 3,000 people get on medications. About 66,000 New Yorkers living with HIV that the Health Department tracks are being effectively treated with AIDS drugs, they said. But they said it was difficult to estimate how many people would eventually need the medications.

Some doctors agree with the Department of Health that it is time to update the guidelines for initiating AIDS drug treatment.

"The New York City health department is a little bit ahead of the curve. In my opinion, the rest of the country will follow and I think it will be pretty quick," said Dr. Michael Saag of the University of Alabama at Birmingham and past chairman of the HIV Medicine Association.

The standard measure of the CD4 count ? a way to measure the strength of the immune system ? is an outdated trigger for therapy, a relic from research on early antiretroviral drugs, Saag said.

"It's anachronism. It's old school. It's yesterday," Saag said. "I agree completely with the New York City health department."

Saag said the cost questions are very important because a brand-name drug can retail for $1,200 to $1,600 per month.

"For sure, they're very expensive drugs and we should be careful about that," he said, though he added that the medications are going generic so costs should come down.

City health officials said they anticipated that the cost for expanding the use of AIDS drugs would be covered by private insurance or by the AIDS Drug Assistance Program, a $270 million program for the uninsured or underinsured that is partially funded through federal dollars.

The health officials said they expect the benefits over the long term would far outweigh the initial costs because there would be fewer hospitalizations and new HIV cases.

"There will be some increasing costs over the short term," said Farley. "But over the long term, it's absolutely the right thing for the epidemic."

HIV experts are split about whether early therapy should be recommended or optional. Besides the high costs, the pills have side effects from nausea to liver damage. Patients unwilling to take them regularly for life could develop drug resistance.

A panel that recently updated U.S. guidelines was divided evenly, with half favoring starting therapy early for everyone and half regarding an early start as elective.

But there's growing evidence that untreated HIV can lead to cancers and heart disease. What's more, antiretroviral drugs are safer, have fewer side effects and work better than they did in the past. New research also indicates that people live better, healthier lives and their partners do as well when they get early treatment.

The new research cited by the city's Health Department in making its recommendations includes a nine-country study whose preliminary results were announced earlier this year and showed that earlier treatment meant patients were 96 percent less likely to spread the virus to their uninfected partners.

Dr. Moupali Das, the director of research at the San Francisco Department of Health HIV/AIDS Epidemiology Section, said its surveillance data indicated that physicians were treating their HIV patients early even before the city recommended doing so. She said the average amount of time from diagnosis to having no virus in the blood went from 32 months in 2004 to eight months in 2008.

"That reflects that the newer medications are more potent and efficacious, and the doctors were likely initiating them earlier," she said.

(AP) ? American universities send tens of thousands of students to study abroad every year, thrusting them into one of the most exciting periods of their lives with a heavy dose of maternal advice: Mix with the locals, but be careful. Don't get in any tight spots. Avoid protests.

It's practical guidance that can be forgotten in the heady political ferment in countries like Egypt, where three American students were recently arrested near demonstrations at Tahrir Square.

The Americans made it safely home, but only after an ordeal they said lasted several days and included being struck, forced to lie for hours in the dark and threatened with guns. It's an experience schools and other students say they try very hard to avoid, balancing personal safety against the desire to engage with the culture that drew them in the first place.

Wittney Dorn, 20, from Appleton, Wis., said she traveled to Egypt because she wanted to study Arabic at the American University in Cairo. In an email Tuesday, the political science major wrote of "the beautiful change" she is seeing as her Egyptian classmates talk about voting for the first time. She said she could understand the urge to get nearer the protests.

"I think the temptation is there, to wrap up in a keffiyeh and try to look like any other Egyptian revolutionary, to feel a little exhilaration from a kind of danger you don't get in America," Dorn wrote.

But she said she wouldn't be doing that. More than 40 protesters were killed, mostly in Cairo, during clashes with police last week and nearly 900 more died in the uprising earlier this year that ousted Hosni Mubarak from power.

"It's not a brilliant idea to go exploring an area where people are being killed, despite how tempting it may be to watch history unfold before one's eyes," wrote Dorn, a student from St. Olaf College in Northfield, Minn.

A survey earlier this month from the nonprofit Institute of International Education found more than 270,000 U.S. students studied abroad during the 2009-10 school year, up about 4 percent from a year earlier. The great majority went to western Europe: Britain, Italy, Spain and France. But the survey found increasing numbers in less traditional destinations; Egypt hosted 1,923 Americans, up 8 percent.

"A lot of students are trying to find places that will help them understand the emerging world," said Peggy Blumenthal, who oversees research at the institute. They are preparing for careers in public health, the sciences and national security, for example, she said.

Many universities and study abroad program coordinators have been trying to prod students out of what can become a comfort zone of huddling with their fellow Americans. The push to engage can be broadening in a "safe" country; in a country with a suddenly dicey political situation, it can be hazardous.

Blumenthal said universities give students traveling abroad a fairly standard list of do's and don'ts, including blending in with the locals, obeying local laws and customs and staying sober. Students should avoid large crowds, seedy areas and steer clear of political events, she said.

"Really, these are not new, these guidelines, but they are even more vigorously stressed now," she said.

Derrik Sweeney, one of the three Americans arrested Nov. 20, said he had heard just such cautions from the American University and the U.S. State Department. He went to demonstrations anyway ? including one in early September and one the Friday before he was arrested.

"I value democracy and liberty, so I wanted to go to those protests more to witness them and to see them than to participate in them," said Sweeney, a student at Georgetown. "I wanted to see history being made."

Sweeney, 19, of Jefferson City, Mo., was arrested along with Luke Gates, 21, who attends Indiana University and is from Bloomington, Ind., and Gregory Porter, 19, who studies at Drexel University and is from Glenside, Pa.

Egyptian officials said they arrested the students on the roof of a university building and accused them of throwing firebombs at security forces fighting with protesters. Sweeney said it didn't happen that way; he said he and the other Americans were with a group of protesters on the street near the Interior Ministry and fled when police dispersed the crowd.

Sweeney said he thought he could recognize danger and leave. He acknowledged it "seems kind of silly" now that he didn't stay away, but he said he doesn't regret it.

"I would have regretted it if I had gone to Egypt and never had gone to a protest," he said.

Georgetown hasn't pulled its other students out of Cairo because the U.S. State Department hasn't recommended it, spokeswoman Stacy Kerr said, but it has reminded them of policies against getting involved in demonstrations.

Drexel University also isn't telling its students to return to the U.S., said Daniela Ascarelli, director of the university's study abroad program. She said the university has spoken with the three students still in Egypt and all of them feel safe and want to stay.

Indiana University urged its two remaining students in Egypt to return to the U.S. One complied, but the other didn't, telling school officials he felt safe and wanted to finish the semester.

Last January, most schools followed a State Department recommendation to bring the students home as protests first broke out in Egypt.

Alex Hanna, a graduate student in sociology at the University of Wisconsin-Madison, was in Egypt in February after the unrest began. Hanna did attend protests, saying he was able to fit in because he's of Egyptian descent.

Hanna said American students who want to lend their support to what they see as a Democratic movement can unwittingly play into the government's hands, allowing it to use reports of foreign protesters to argue the dissent is being stirred up by outsiders.

"U.S. students going over there can actually hurt the efforts," he said. "They need to be cognizant of that."

Katrina Gray, 22, of Madison, Wis., was finishing a year of study in Alexandria, Egypt, when she was evacuated in January. Gray was disappointed to miss "a huge part of history" but said she never considered defying the University of Wisconsin's order to come home.

"My mother would have killed me," she said.

Scientists use laser imaging to assess safety of zinc oxide nanoparticles in sunscreen

ScienceDaily (Nov. 30, 2011) ? Ultra-tiny zinc oxide (ZnO) particles with dimensions less than one-ten-millionth of a meter are among the ingredients list of some commercially available sunscreen products, raising concerns about whether the particles may be absorbed beneath the outer layer of skin. To help answer these safety questions, an international team of scientists from Australia and Switzerland have developed a way to optically test the concentration of ZnO nanoparticles at different skin depths. They found that the nanoparticles did not penetrate beneath the outermost layer of cells when applied to patches of excised skin.

The results, which were published this month in the Optical Society's (OSA) open-access journal Biomedical Optics Express, lay the groundwork for future studies in live patients.

The high optical absorption of ZnO nanoparticles in the UVA and UVB range, along with their transparency in the visible spectrum when mixed into lotions, makes them appealing candidates for inclusion in sunscreen cosmetics. However, the particles have been shown to be toxic to certain types of cells within the body, making it important to study the nanoparticles' fate after being applied to the skin. By characterizing the optical properties of ZnO nanoparticles, the Australian and Swiss research team found a way to quantitatively assess how far the nanoparticles might migrate into skin.

The team used a technique called nonlinear optical microscopy, which illuminates the sample with short pulses of laser light and measures a return signal. Initial results show that ZnO nanoparticles from a formulation that had been rubbed into skin patches for 5 minutes, incubated at body temperature for 8 hours, and then washed off, did not penetrate beneath the stratum corneum, or topmost layer of the skin. The new optical characterization should be a useful tool for future non-invasive in vivo studies, the researchers write.

Apple II drum sequencer surfaces for chiptune composers

No, this isn't a recycled news item from the 1980s -- it's 2011, and MJ Mahon and 8 Bit Weapon have just announced the release of the Apple II DMS Drummer, a wavetable-based drum sequencer for Apple II-era machines. The monophonic synth reproduces eight drum sounds like bass, snare, rim shot, hand clap, tom, hat open, hat closed and "lazer," along with a sequencer that lets you plug in up to 16 drum patterns across 256 slots. Seems like just the thing for chiptune composers hankering for a way to make authentic eight-bit drum tracks using vintage Apple hardware. System requirements call for an Apple IIe, IIc, IIc+ or IIgs with 80-column capability and a 5.25-inch floppy drive -- you know, pretty modern stuff. A limited demo version is available, but if that doesn't satisfy, you can either buy it on a floppy for $14.95 or download a .dsk disk image for $9.95. Oh, and neither require a time-traveling DeLorean to go back to 1985.

Jackson's family calls for stiff sentence for doc (AP)

LOS ANGELES ? A lawyer for Michael Jackson's family has told a judge sentencing the doctor who caused the singer's death that the family is not seeking revenge but wants a stiff sentence that serves as a warning to opportunistic doctors.

Attorney Brian Panish did not specifically request the maximum term of four years in jail for Dr. Conrad Murray, but said Tuesday the cardiologist should be punished in a way that reminds physicians that they cannot sell their services to the highest bidder.

Panish represents family matriarch Katherine Jackson and the singer's three children in a civil lawsuit.

The statement by Panish at a sentencing hearing included elements representing the views of Jackson's children, parents and siblings.

Murray was convicted on Nov. 7 of involuntary manslaughter.
