IVR Process Can Challenge Sex Life | Psych Central News

IVR Process Can Challenge Sex LifeA new study discovers that infertility treatment can negatively impact a women?s sex life. Despite the importance of sex in conceiving a child, little attention has been given to the sexual dynamics of couples as they work to overcome infertility challenges.

?Sex is for pleasure and for reproduction, but attention to pleasure often goes by the wayside for people struggling to conceive,? said Nicole Smith, a doctoral student with Indiana University?s Center for Sexual Health Promotion.

Smith is conducting the study in collaboration with Jody Lyne? Madeira, Ph.D.

?With assisted reproductive technologies (ART), couples often report that they feel like a science experiment, as hormones are administered and sex has to be planned and timed. It can become stressful and is often very unromantic and regimented; relationships are known to suffer during the process.?

Researchers say the study is one of the first in the United States to examine women?s sexual experiences while undergoing assisted reproductive technologies. Investigators used a Sexual Functioning Questionnaire to assess the impact of IVF treatment on couples? sexual experiences.

Compared to a sample of healthy women, women undergoing IVF reported significantly less sexual desire, interest in sexual activity and satisfaction with their sexual relationship. They had more difficulty with orgasm and were more likely to report sexual problems such as vaginal pain and dryness.

Experts have recognized that emotional and relationship challenges intensify as a couple?s use of ART proceeded. Attention to challenges in having sex has somehow escaped the purview of key parties.

When couples meet with their physicians, their sex life might not top the list of issues they want to discuss, either because of unease talking about the subject or simply because they have so many other important issues to discuss.

Still, Smith and Madeira say, the doctor-patient relationship is key, and couples can be told up front about the potential sexual side effects and resources that can help.

If they have issues with dryness, for example, they could be counseled on remedies such as purchasing lubricant or other sexual enhancement products. In addition to referring couples to mental health counselors, reproductive endocrinologists could also refer them to sex therapists.

?There?s just a dearth of knowledge on how infertility affects sexual behavior,? Madeira said. ?The focus is more likely to be on the social and support dimensions of the relationship, but sex is a big part of that. Just letting patients know they aren?t alone in this would be helpful.?

If more information about sexual challenges becomes available, couples might find it on their own.

?Women interested in ART are generally well-educated and tend to spend time researching these issues,? Madeira said. ?They would be very responsive to this information, and proactive.?

The study involved 270 women who completed an online questionnaire; interviews with 127 men and women using IVF to try to conceive; and interviews with 70 professionals, including physicians, nurses, mental health experts and other providers who work directly with patients.

IVF is a procedure in which mature eggs are retrieved from a woman?s ovaries and fertilized by sperm in a lab, forming embryos. The embryo(s) are then implanted in the woman?s uterus. It is considered an effective procedure but one that is used after couples try several other less invasive procedures.

By the time couples begin IVF, they might have been trying to conceive for many years. Nine percent of the women in their study had been through five IVF cycles, which could take at least a year.

Here are some of their other findings:

  • Women who reported being sexually active with a partner in the past month also were more likely to engage in masturbation and report fewer sexual problems;
  • The women reported similar problems with sexual function regardless of the type or source of infertility involved: male factor, female factor, or both male and female factor;
  • Hormonal treatments used in assisted reproductive technologies likely affect women?s sexual experiences and pain, but these effects are not as well understood and receive less priority than other conditions, such as heart disease and cancer.

Wireless Computers: Formerly A Luxury, Now A ... - Retirement Homes

It?s sometimes easy to forget how much technology has changed in the last 10 years. Personally, I grew up with a generation that had Internet access from the moment it was available to everyone, nearly 2/3 of my life. At the beginning, getting online was much different. Our family computer was a $3000, large and bulky, tan colored machine that had its own room in our house. It used a loud modem to connect to the only phone line we had, which meant no one could make a call while the Internet was in use.

Today, getting online is easier and more convenient than ever before. With the introduction of WIFI, which is the name commonly given to the concept of connecting to the Internet with a device wirelessly using radio waves, everything changed. Our computers (laptops) got smaller and more powerful, which promoted using these tools in a more mobile way. We were no longer forced to sit in our computer rooms anymore. We had the freedom to sit on the couch and check our email, or watch a cooking tutorial while preparing dinner in the kitchen. WIFI made it possible for the Internet to be available to everyone virtually anywhere. What a game changer!

Connecting to the Internet using WIFI is also the technology that makes new gadgets such as tablets, smart phones, and new laptops possible, as these devices do not have another means to get online. So, when you walk around your retirement home sharing photos of your grandchildren on Facebook with your neighbors, imagine trying to do the same with a long wire attached to the wall. It would actually seem ridiculous. Future technologies will undoubtedly all use WIFI to access the Internet. Wires will soon be a thing of the past.

Because WIFI is so common, it?s important that everyone understands a few basic concepts about it, to use it confidently and safely. First, if you have your own WIFI connection at home, be sure to setup a WIFI password. This will ensure that only the people who know your password can get access to you WIFI connection. Second, when using public WIFI, like at Starbucks or your modernized retirement home, avoid making online purchases or doing online banking. With no WIFI password, anyone could view all the activity on the public WIFI connection, which includes your credit card number and bank information. Reserve this type of online activity for at home, when you?re using a private, password protected WIFI connection.

Finally, it?s important to know how to make your WIFI connection signal as strong as possible, so your Internet loads quickly. Be sure to have the WIFI router (electronic box with an antenna that transmits wireless radio waves) at a high elevation, wherever it?s setup. Also, keep it away from other electronic devices. This will help create a wide open area for the WIFI Internet connection to be projected and will decrease the amount of electronic interference other technologies might create.

Have fun out there in our WIFI enabled world. Just imagine when entire cities offer free WIFI to everyone?wow! WIFI truly is a technology for seniors.

Australia's Sermanni hired as new US women's coach

(AP) ? When Tom Sermanni shook hands with Pia Sundhage after her last game as coach of the U.S. women's soccer team, he should have asked her for a few tips.

Sermanni was hired Tuesday to replace Sundhage, who led the Americans to back-to-back Olympic gold medals and their first World Cup final in 12 years. Sermanni has spent the last eight years as Australia's coach, taking the Matildas to the quarterfinals of the last two Women's World Cups.

"He has the knowledge, experience and vision to take on the challenge of keeping our team at the top of the world," U.S. Soccer Federation president Sunil Gulati said in a statement. "He has a tremendous passion for the game, knows the American players, understands our system and knows the process of preparing a team for a World Cup tournament."

Sermanni, a 58-year-old originally from Glasgow, Scotland, has spent much of the last 20 years in Australia, where he is credited with transforming the Matildas into one of the world's top programs. In addition to their quarterfinal appearances at the 2007 and 2011 World Cups, the young Australians won the 2010 Asian Women's Cup. Their runner-up finish at the same tournament in 2006 earned Sermanni Asian Football Confederation coach of the year honors.

The Australians are ninth in the world, matching their highest ranking.

Sermanni also coached Australia from 1994-97, leading the Matildas to their first appearance in a World Cup, the 1995 tournament in Sweden. He was among 10 candidates for FIFA's 2011 Women's Coach of the Year.

"Tom's legacy for Women's Football in Australia will be felt for many years to come as he has helped transform our women's national team to a very professional and competitive group of players," Ben Buckley, CEO of Football Federation Australia, said in a statement. "Tom will always be considered a close friend of Australian football no matter where he is in the world."

Sermanni was selected after a five-person search committee, which included Mia Hamm, considered more than 30 candidates. The current U.S. players said they didn't care whether the new coach was male or female, American or foreign-born, so long as the right coach was selected.

The coaches of both U.S. national teams are foreign-born, with German-born Jurgen Klinsmann, a longtime California resident, coaching the men.

"Someone who's good enough, that's all I care about," Abby Wambach said earlier this month. "Be the person who brings the World Cup back."

Sundhage was 91-6-10 in her five years with the Americans, including a 23-1-1 record this year, and the U.S. was ranked No. 1 in the world for most of her tenure. She resigned Sept. 1 to return to her native Sweden, where she is now the women's national team coach.

"We need a strong person to come in and add to the history that this team, specifically, has created in the last two years," Wambach said. "... This team is scary good, and we need to have someone who can put all the Xs and Os together."

After Sermanni's hiring was announced, Megan Rapinoe, Alex Morgan and Wambach welcomed him via Twitter.

"really pumped about (at)TomSermanni being the new uswnt head coach!!! Welcome. (hashtag)movingforward," Wambach said.

Sermanni has experience coaching young players, which will be key as the U.S. begins integrating its next generation. Though veterans like Wambach, captain Christie Rampone and Shannon Boxx have all talked of playing through the 2015 World Cup in Canada, the next major tournament, there is plenty of depth and talent at the lower levels, too. The U-20 team just won the World Cup, and the U-23 team won both tournaments it played this year.

Sundhage had also begun changing the Americans' style of play. As the game evolves and improves around the world, relying on the advantages it has in size, speed and power is no longer enough for the U.S. Sundhage introduced a Barcelona-style attack that relied on creativity and ball possession, and Sermanni will have to decide whether to continue that or not.

"U.S. Soccer has always been at the forefront of supporting the women's game, and it's exciting to coach the team in this next chapter of its history," Sermanni said. "After coaching against many of these players for years, I am looking forward to working with an accomplished group of veterans while integrating the numerous talented young players who are itching for a chance to prove themselves.

"I'm honored to have this opportunity to work with tremendous players and in a program that has had such a tradition of success," he added.

Sermanni does not take over officially until Jan. 1, and will coach Australia in the East Asian Cup Qualification tournament from Nov. 20-24 in Shenzen, China. Interim coach Jill Ellis will lead the Americans in exhibitions against Ireland on Nov. 28 in Portland, Ore., and on Dec. 1 in Glendale, Ariz., as well as three games that have yet to be announced.

A midfielder, Sermanni played professionally from 1971-89 at clubs in Scotland, England, Australia and New Zealand, including Blackpool and Torquay, and scored more than 50 goals. He got into coaching soon after, and has had stints as both a men's and women's coach in Japan, the U.S. and Malaysia, in addition to Australia.

Study reveals impact of public DNS services; Researchers develop tool to help

ScienceDaily (Oct. 25, 2012) ? A new study by Northwestern University researchers has revealed that public DNS services could actually slow down users' web-surfing experience. As a result, researchers have developed a solution to help avoid such an impact: a tool called namehelp that could speed web performance by 40 percent.

Through a large-scale study involving more than 10,000 hosts across nearly 100 countries, Fabi?n Bustamante, associate professor of electrical engineering and computer science at Northwestern's McCormick School of Engineering and Applied Science, and his team found that one cause of slow web performance is a growing trend toward public Domain Name Systems (DNS), a form of database that translates Internet domain and host names into Internet Protocol (IP) addresses.

DNS services play a vital role in the Internet: every time a user visits a website, chats with friends, or sends email, his computer performs DNS look-ups before setting up a connection. Complex web pages often require multiple DNS look-ups before they start loading, so users' computers may perform hundreds of DNS look-ups a day. Most users are unaware of DNS, since Internet Service Providers (ISP) typically offer the service transparently.

Over the last few years, companies such as Google, OpenDNS, and Norton DNS have begun offering "public" DNS services. While "private" DNS services, such as those offered by ISPs, may be misconfigured, respond slowly to queries, and go down more often, public DNS services offer increased security and privacy, and quicker resolution time. The arrangement is also beneficial for public DNS providers, who gain access to information about users' web habits.

Bustamante and his team found that while using public DNS services may provide many benefits, users' web performance can suffer due to the hidden interaction of DNS with Content Delivery Networks (CDNs), another useful and equally transparent service in the web.

CDNs help performance by offering exact replicas of website content in hundreds or thousands of computer servers around the world; when a user types in a web address, he is directed to the copy geographically closest to him. Most popular websites -- more than 70 percent of the top 1,000 most popular sites, according to the Northwestern study -- rely on CDNs to deliver their content quickly to users around the world.

But researchers found that using public DNS services can result in bad redirections, sending users to content from CDN replicas that are three times farther away than necessary.

Public DNS and CDN services are working to address the problem, but current users are left with two mediocre options -- bad web performance through public DNS services or bad security and privacy support through private DNS services.

Now Bustamante and his group have developed a tool called namehelp that may let users have their cake and eat it, too -- by using public DNS services without compromising on web performance.

namehelp runs personalized benchmarks in the background, from within users' computers, to determine their optimal DNS configuration and improve their web experience by helping sites load faster. If it finds that a user is receiving less than optimal web performance, namehelp automatically fixes it by cleverly interacting with DNS services and CDNs to ensure the user gets his content from the nearest possible copy.

You can download namehelp today from: http://aqualab.cs.northwestern.edu/projects/namehelp.

The paper describing the research is titled "Content Delivery and the Natural Evolution of DNS: Remote DNS Trends, Performance Issues and Alternative Solutions." The team's findings will be presented at the Internet Measurement Conference (IMC 2012) in Boston this November. In addition to Bustamante, authors on the paper are lead author John S. Otto, Mario A. Sanchez, and John P. Rula, all of Northwestern.

Gene mutation identifies colorectal cancer patients who live longer with aspirin therapy

ScienceDaily (Oct. 24, 2012) ? Aspirin therapy can extend the life of colorectal cancer patients whose tumors carry a mutation in a key gene, but has no effect on patients who lack the mutation, Dana-Farber Cancer Institute scientists report in the Oct. 25 issue of the New England Journal of Medicine.

In a study involving more than 900 patients with colorectal cancer, the researchers found that, for patients whose tumors harbored a mutation in the gene PIK3CA, aspirin use produced a sharp jump in survival: five years after diagnosis, 97 percent of those taking aspirin were still alive, compared to 74 percent of those not using aspirin. By contrast, aspirin had no impact on five-year survival rates among patients without a PIK3CA mutation.

"Our results suggest that aspirin can be particularly effective in prolonging survival among patients whose colorectal cancer tests positive for a mutation in PIK3CA," said the study's senior author, Shuji Ogino, MD, PhD, of Dana-Farber, Brigham and Women's Hospital, and the Harvard School of Public Health. "For the first time, we have a genetic marker that can help doctors determine which colorectal cancers are likely to respond to a particular therapy." He cautions that the results need to be replicated by other researchers before they can be considered definitive.

While aspirin is often prescribed for colorectal cancer patients, doctors haven't been able to predict which patients will actually benefit from the treatment. The new finding suggests that the survival benefit is limited to the 20 percent whose tumors have the PIK3CA mutation.

For the remaining patients, aspirin may still be used, but it is likely to be much less effective and can sometimes lead to gastrointestinal ulcers and stomach bleeding.

The study was prompted by previous research that suggested that aspirin blocks an enzyme called PTGS2 (cyclooxygenase-2), causing a slowdown in the signaling activity of another enzyme, PI3K. That led researchers to hypothesize that aspirin could be especially effective against colorectal cancers in which the PIK3CA gene -- which provides a subunit of PI3K -- is mutated.

To conduct the study, investigators obtained data on 964 patients with rectal or colon cancer from the Nurses' Health Study and the Health Professionals Follow-up Study -- long-term tracking studies of the health of tens of thousands of people. The data included information on the patients' use of aspirin after diagnosis and the presence or absence of PIK3CA mutations in their tumor tissue.

The study, which combines the study of disease-related genes and research into large populations of individuals, represents a new, hybrid field which Ogino has termed molecular pathology epidemiology. "The field may help us bring together information from two frontiers of cancer research -- at both the molecular and population levels -- in ways that are beneficial to patients," he said.

The study was supported in part by grants from the National Institutes of Health (P01 CA87969, P01 CA55075, P50 CA127003, R01 CA149222, R01 CA137178, and R01 CA151993); the Bennett Family Fund for Targeted Therapies Research; the Entertainment Industry Foundation through the National Colorectal Cancer Research Alliance; the Frank Knox Memorial Fellowship at Harvard University; and a Damon Runyon Clinical Investigator Award.

Adidas wins latest legal round in lightweight shoe battle vs. Nike ...

Adidas appears to have won the latest round in the legal tangle over Nike's contention that Adidas infringed on Nike's development of a super-lightweight running shoe.

The Nuremberg District Court today said "the granted injunction cannot be sustained," according to a statement issued by Germany-based Adidas. "It is to be expected that on November 7, 2012, the Court will set aside its initial decision and decide in favour of adidas."

?Nike, the Oregon-based company, sought and obtained an injunction Aug. 28, alleging the adizero Primeknit was a copy of the Nike Flyknit.

Nike, the world's largest sporting goods company, contended that its Flyknit running shoes were the first to offer a technology in which woven threads formed the shoe's upper. Nike executives have said the Flyknit technology has far-reaching potential, from altering shoe production methods to curtailing shoe construction waste.

The Flyknit running shoe, which has a line that was co-developed by Nike chief executive Mark Parker, was introduced at a Summer Olympics-themed event in New York in February.

But on July 25, about a week before the Summer Olympics' opening, Adidas, the world's second-largest sporting goods company, introduced the Primeknit shoe, a remarkably similar product to Nike's Flyknit.

Adidas, in its statement today, said the original Aug. 28 injunction was set aside just days after it was granted in advance of today's hearing. ?

"Adidas vigorously denies the alleged patent infringement, and has filed for cancellation of the patent, with documents showing that the technology has been known since the 1940s," says the statement the company issued today.

Nike, in a statement responding to the court ruling, said, "This is just one step in the process. We will continue to aggressively protect our intellectual rights, including through the conclusion of this interim injunction proceeding as well as in a formal infringement case."
