Que tristeza, pero lo escrito en esta nota es factible, les dejo el artículo para escuchar sus comentarios

iPhone Hackeado en 20 segundos: "Todos sabemos por los anuncios de televisión y los comentarios de usuarios de Apple que los Mac y los iPhone son seguros, así que no hay nada que temer ante la noticia de Engadget de que se puede acceder a la base de datos de SMS del iPhone solo accediendo con el a una página web maliciosa. Los concursantes del Pwn2Own no harán público el método para llevarse el premio de 15.000 dólares, pero queda claro que es posible acceder como mínimo a toda la información de los SMS enviados, recibidos e incluso los borrados de un iPhone."

Oral Sex & Risk of Cancer

Sex virus blamed for rise in head and neck cancers


By Kate Kelland

LONDON -- The number of serious head and neck cancers linked to a virus spread by oral sex is rising rapidly and suggests boys as well as girls should be offered protection through vaccination, doctors said on Friday.

Despite an overall slight decline in most head and neck cancers in recent years, cases of a particular form called oropharyngeal squamous cell carcinoma (OSCC) have increased sharply, particularly in the developed world.

This growth seems to be linked to cancers caused by the human papillomavirus (HPV), the scientists said in a report in the British Medical Journal.

Two vaccines -- Cervarix, made by GlaxoSmithKline, and Gardasil, made by Merck & Co -- can prevent HPV, which causes virtually all cases of cervical cancer, the second most common cancer in women worldwide.

Many rich nations have launched HPV immunisation programmes for girls to try to protect them from the common sexually transmitted virus before they become sexually active.

The scientists, led by Hisham Mehanna of the Institute of Head and Neck Studies at Britain's University Hospital Coventry, said that while including boys in immunisation plans was previously seen as too expensive, it may be time to look again.

"We need to look at the evidence again to re-evaluate the cost-effectiveness of male children in light of this new and rapidly rising incidence," he said in a telephone interview.

More than 500,000 cases of cervical cancer are diagnosed annually in women and it kills around 200,000 a year. Head and neck cancer is the sixth most common cancer among men and women, with about 640,000 new cases each year worldwide.

A recent study found the risk of developing oropharyngeal carcinoma was linked to a history of six or more lifetime sexual partners, four or more lifetime oral sex partners, and, for men, an earlier age at first sexual intercourse.

"Sexual transmission of HPV -- primarily through orogenital intercourse -- might be the reason for the increase in incidence of HPV related oropharyngeal carcinoma," wrote Mehanna.

The experts pointed to recent studies which showed a 70 percent increase in the detection of HPV in biopsies taken to diagnose oropharyngeal carcinoma in Stockholm since the 1970s.

HPV-related cancer was also reported in 60 to 80 percent of recent biopsy samples in studies in the United States, compared with 40 percent in the previous decade, they wrote.

Mehanna said the findings had other important health implications. Patients with HPV-related head and neck cancers are typically younger and employed, he said, and because their tumours appear to be less deadly than those caused by factors like smoking and drinking, patients may also live longer with the physical and psychological effects of treatment.

"This means they would need prolonged support from health, social, and other services, and may require help in returning to work," he wrote. (Editing by Elizabeth Fullerton)

Moderate drinking helps heart, but don't binge

Tue, March, 23, 2010
Reuters Health E-Line
Moderate drinking helps heart, but don't binge
NEW YORK -- One or two alcoholic drinks a day can help healthy people-and heart patients-live longer, new research confirms.
But the two new studies-one of nearly 250,000 US adults, the other an analysis of eight previous studies of more than 16,000 people with heart disease and other problems related to clogged arteries-also show that drinkers who exceeded recommended limits for alcohol consumption saw no heart health benefits.
"No question, heavy or binge drinking can have adverse health outcomes," Dr. Simona Costanzo and colleagues from Catholic University in Campobasso, Italy, warn in their report.
However, they add, doctors should tell their patients with heart disease and other clogged artery-related problems, together known as cardiovascular disease, that moderate alcohol consumption-a drink a day for women, two for men-"should not be harmful to their health."
There is considerable evidence that moderate drinking helps reduce the risk of heart disease and death from heart-related causes, likely due to the fact that drinking alcohol is linked to higher levels of "good" cholesterol.
However, questions have been raised about how research on alcohol and health is done, Dr. Kenneth J. Mukamal of Beth Israel Deaconess Medical Center in Boston and his team, the authors of the other study, write.
To address these issues, Mukamal and his colleagues looked at nine years' worth of data from the National Health Interview Survey from 1987 to 2000, including 245,207 people in all. Census bureau employees perform the survey in person every year, sampling a representative group of around 20,000 to 40,000 US citizens.
The researchers correlated the information on alcohol consumption with data from the National Death Index up until 2002, identifying 10,670 deaths from cardiovascular causes among survey participants.
The risk of dying due to heart disease or stroke was about the same for people who had never drank, meaning they had less than 12 drinks in their lifetime; people who drank infrequently, meaning they had more than 12 drinks in their life, but never drank more than 12 drinks in a given year; and ex-drinkers, who had more than 12 drinks in their lives and had consumed more than 12 drinks per year in the past, the researchers found.
But for light drinkers, defined as men or women who had three drinks a week or less, risk was 31 percent lower than for non-drinkers.
Among moderate drinkers (women who had three to seven drinks each week and men who had three to 14 drinks a week), risk was 38 percent lower than it was for abstainers.
Heavy drinkers, meaning women who had more than seven drinks a week and men who downed more than 14 drinks weekly, had the same cardiovascular death risk as non-drinkers.
Mukamal and his team also found that people who had two drinks on days when they consumed alcohol were "consistently" at lower risk than people who had three or more drinks per drinking day.
The study's strengths include its size, the fact that it included a broad sample of the US population, and its ability to separate people who had never drank or only rarely drank from those who had drank previously but quit, Mukamal noted in an E-mail interview.
"Our results suggest that even in this well-designed study, the lower risk linked to moderate drinking remains," he told Reuters Health. "However, it also clearly confirms that the benefit is lost for excessive drinking."
People with cardiovascular disease get mixed messages on whether moderate drinking is OK. The US Food and Drug Administration advises people with heart disease who drink alcohol to quit, but guidelines from the American Heart Association say they can drink in moderation, Costanzo and her colleagues point out in their report.
To better understand the risks and potential benefits of alcohol for cardiovascular patients, the researchers identified eight studies including 16,351 patients with cardiovascular disease. They analyzed the relationship between alcohol consumption and death due to cardiovascular disease among study participants, as well as the association between drinking and overall mortality.
The Italian team found a similar benefit pattern to the one Mukamal and his colleagues identified: heart patients who drank were less likely to die than abstainers, and the maximum benefit was seen for those who consumed between 5 to 10 grams of alcohol a day. A standard drink-12 ounces of beer or 5 ounces of wine, for example-contains about 14 grams of alcohol, according to the Centers for Disease Control and Prevention.
But people who drank more than about 25 grams of alcohol daily had overall mortality and cardiovascular death risks exceeding those of abstainers, and the more they drank, the higher the risk.
"Cardiovascular patients should be informed that low-to-moderate alcohol consumption (1 drink/day for women or up to 2 drinks/day for men) should not be harmful to their health," Costanzo and her team say. However, patients who don't drink regularly shouldn't be encouraged to start, they add, and those who drink heavily should be encouraged to quit or at least sharply reduce their alcohol intake.
"The risks of moderate drinking differ by sex, age, personal history, and family history," Dr. Arthur L. Klatsky of Kaiser Permanente Medical Center in Oakland, California, notes in an editorial accompanying the studies. While the case for alcohol's heart benefits is "compelling," he adds, "as is often the case in medical practice, advice about lifestyle must be based on something less than certainty."
He concludes: "What is required is a synthesis of common sense and the best available facts."

Glaxo's rotavirus vaccine use suspended

Mon, March, 22, 2010
Reuters News
Glaxo's rotavirus vaccine use suspended

* Merck vaccine not affected
* Suspension is temporary - no evidence of harm
* Rotavirus vaccines have troubled history
By Maggie Fox, Health and Science Editor

Doctors should temporarily stop using GlaxoSmithKline Plc's Rotarix vaccine against a diarrhea-causing virus called rotavirus because it is contaminated with an apparently harmless pig virus, regulators and the company said on Monday.
Doctors should instead use Merck and Co Inc's RotaTeq rotavirus vaccine, which is made using a different method and which shows no evidence of the virus, the U.S. Food and Drug Administration said.
The FDA and the company both found DNA from the virus in the vaccine. It is not clear whether whole virus is in the vaccine or just pieces of its DNA.
"We do believe the product is safe," FDA Commissioner Dr. Margaret Hamburg told reporters in a telephone briefing. Most children in the United States have been vaccinated with Merck's vaccine, which came onto the market sooner than Rotarix, she said.
Hamburg said the FDA was acting out of an abundance of caution. Rotavirus vaccines have a troubled history -- Wyeth's Rotashield was pulled off the market in 1999 after it was linked with a rare but deadly bowel obstruction called intussusception.
The contaminating virus in Rotarix, called porcine circovirus type 1 or PCV-1, is not known to cause disease.
"PCV-1 does not multiply in humans and is not known to cause illness in humans. It is found in everyday meat products and is frequently eaten with no resulting disease or illness," the company said in a statement.
The FDA said its vaccine advisory committee would meet within the next four to six weeks to review the issue.
DEATHS FROM ROTAVIRUS
Circoviruses are tiny animal viruses. Porcine circovirus type 2 or PCV-2 is believed to cause postweaning multisystemic wasting syndrome in young piglets, marked by diarrhea and an inability to gain weight. PCV-1 is related but appears to cause no disease in pigs.
Tests in human cells showed PCV-2 could damage the cells but PCV-1 did not.
Rotavirus can kill babies and young children within days by causing severe diarrhea. It kills more than 500,000 children under 5 every year, nearly half of them in Africa.
Rotavirus vaccines are now given as part of the standard immunizations in developed countries such as Canada and the United States.
"No safety issue has been identified by external agencies or GSK. GSK is committed to patient safety and to the highest manufacturing standards for all our vaccines and medicines. We are already working closely and discussing this finding with regulatory agencies around the world," said Thomas Breuer, Glaxo's chief medical officer.
Breuer said 69 million doses of Rotarix had been distributed with no evidence of a safety problem.
Hamburg said about 1 million U.S. children have received Rotarix, which came onto the market in 2008.
The DNA from the virus was found by accident, when the company ran checks using new molecular detection techniques. The virus has apparently been there since the vaccine was first developed.
"GSK is now reviewing how best to replace, in a timely way, the cell bank and virus seeds used as base production material," the company said. It said it would continue to make Rotarix, however, using current methods.
Hamburg said regulators in other countries might opt to continue using Rotarix, as the real threat of rotavirus outweighs any theoretical risk of the pig virus.
In afternoon New York Stock Exchange trading, Merck shares were up 54 cents or 1.4 percent to $38.60, while GlaxoSmithKline shares were up 49 cents or 1.3 percent to $39.06. (Reporting by Lisa Richwine and Maggie Fox, editing by Gerald E. McCormick)

Effects of Internet Use on Health and Depression: A Longitudinal Study

Estimados
Me llegó vía RSS los comentarios de este estudio longitudinal que habla sobre los efectos de Internet.
Chequenlo, vale la pena
Saludos

Effects of Internet Use on Health and Depression: A Longitudinal Study: "Background: The rapid expansion of the Internet has increased the ease with which the public can obtain medical information. Most research on the utility of the Internet for health purposes has evaluated the quality of the information itself or examined its impact on clinical populations. Little is known about the consequences of its use by the general population. Objective: Is use of the Internet by the general population for health purposes associated with a subsequent change in psychological well-being and health? Is the effect different for healthy versus ill individuals? Does the impact of using the Internet for health purposes differ from the impact of other types of Internet use? Methods: Data come from a national US panel survey of 740 individuals conducted from 2000 to 2002. Across three surveys, respondents described their use of the Internet for different purposes, indicated whether they had any of 13 serious illnesses (or were taking care of someone with a serious illness), and reported their depression. In the initial and final surveys they also reported on their physical health. Lagged dependent variable regression analysis was used to predict changes in depression and general health reported on a later survey from frequency of different types of Internet use at an earlier period, holding constant prior depression and general health, respectively. Statistical interactions tested whether uses of the Internet predicted depression and general health differently for people who initially differed on their general health, chronic illness, and caregiver status. Results: Health-related Internet use was associated with small but reliable increases in depression (ie, increasing use of the Internet for health purposes from 3 to 5 days per week to once a day was associated with .11 standard deviations more symptoms of depression, P = .002). In contrast, using the Internet for communication with friends and family was associated with small but reliable decreases in depression (ie, increasing use of the Internet for communication with friends and family purposes from 3 to 5 days per week to once a day was associated with .07 standard deviations fewer symptoms of depression, p = .007). There were no significant effects of respondents’ initial health status (P = .234) or role as a caregiver (P = .911) on the association between health-related Internet use and depression. Neither type of use was associated with changes in general health (P = .705 for social uses and P = .494 for health uses). Conclusions: Using the Internet for health purposes was associated with increased depression. The increase may be due to increased rumination, unnecessary alarm, or over-attention to health problems. Additionally, those with unmeasured problems or those more prone to health anxiety may self-select online health resources. In contrast, using the Internet to communicate with friends and family was associated with declines in depression. This finding is comparable to other studies showing that social support is beneficial for well-being and lends support to the idea that the Internet is a way to strengthen and maintain social ties.

El inventor del móvil “jubila” su iPhone y se pasa a Android: "


El hombre que veis en la foto es Martin Cooper, el inventor del teléfono móvil y antiguo poseedor de un iPhone revela en una entrevista que lo ha cambiado por un Motorola Droid. A continuación sus motivos y una entrevista bastante interesante.

Martin Cooper de más de 80 años, nos habla en la entrevista sobre bastantes cosas acerca de la actualidad de los móviles, aunque muchas relacionadas con temas de salud y con el mercado estadounidense, y también de como contribuyó a su creación.

Al final de la entrevista suelta una “perla” como esta:

“Siempre tengo el móvil más actual, y los pruebo todos, tan sólo porque gente como tú sigue preguntándome. Ahora mismo estoy usando el Droid, porque quiero tener experiencia con el sistema operativo Android, y por ahora tengo resultados favorables”.

Teniendo en cuenta que antes del Droid, donó su iPhone a su nieto, nos preguntamos dos cosas:

1- ¿Cuál será su próximo móvil?

2- Cuando lo cambie ¿donará su Droid a este humilde redactor de Gizmodo?

Free iPhone medical apps that every doctor can use

Free iPhone medical apps that every doctor can use: "
Free iPhone medical apps that every doctor can use
by Iltifat Husain, Yousif Alkadhi, MD, and Satish Misra

If you’re a physician, medical student, or in any other health care related field, trying to find the best free medical apps for the iPhone is a hassle.

Apps such as “Dream Meanings”, “Relax Ocean waves”, and “Stool Scanner Lite” dominate the Top Free Medical Apps list in the App Store. Our top 10 iPhone medical apps list contains no such app, and this isn’t a re-hash of the top downloaded free medical apps either. Rather, this list contains the top 10 free iPhone apps health care professionals and students can actually use on a day to day basis.



1) Medscape

We mentioned this app when it was released in the summer of 2009. At the time I doubt many thought it would ever eclipse Epocrates in the top free medical apps section of the App Store, but with significant recent updates it’s accomplished this feat.

This app always had a great drug reference section, with over 6,000 generic, brand, and OTC drugs, along with a drug interaction checker. But with recent updates, Medscape now has a Diseases and Conditions section, along with a Clinical Procedures section. These added sections aren’t just fluff, they actually contain concise and useful information, with videos and pictures to boot. We plan on doing a full review in the near future.

Cost: Free

2) Epocrates

The free version of Medscape might be ranked higher on our list, and in the App Store, but I guarantee almost every medical professional still has at least the free version of Epocrates. My peers and I often joke about how Epocrates is the “most trusted name in Medicine” – because it’s the one app med schools and medical institutions aren’t afraid of pushing.

The free version, called Epocrates Rx, includes: Drug interactions, Pill Identifier, Drug Info, and Medical Calculator. Surprisingly, Medscape doesn’t have a medical calculator, you would think this added functionality would be easy to do. In our review of Epocrates, we go over all the different versions in details, along with pricing – we were definitely impressed.

Cost: Free

3) iRadiology

This app is a must download if you’re a resident or a medical student. Even if you’re not in that category, you might want to download this app just for fun. iRadiology has a catalog of over 500 radiology cases designed to help medical students and residents improve their plain film, CT, and MRI reading skills.

The cases are derived from Dr. Gillian Lieberman, who is currently the Director of Harvard Medical Student training and Associate Director of the Residency Program at Beth Israel Medical Center. We interviewed her when iRadiology was released – and she provided some great insight into the inspiration for the app.

Cost: Free

4) MedPage Today Mobile

What’s not to like about MedPage Today? The website is a fantastic resource for medical professionals, and a lot of the content is in partnership with the University of Pennsylvania School of Medicine – further securing its academic credentials. Their motto is, “Putting Breaking Medical News Into Practice”, and this app helps you with this cause via mobile access.

In addition, you can get audio and video through this app, allowing you to get CME credits while using MedPage Today mobile. With the most recent update, MedPage Today mobile now allows you to do a full text search of all articles published on their website since 1/1/07, definitely a welcome addition.

Cost: Free

5) Medical Radio

This is a product of ReachMD, probably most famous for its XM Satellite Radio broadcast feeds (XM 160) of medical information – and these feeds are available live through this app. MedicalRadio allows you to keep up to date with changing clinical guidelines, and I’ve found the medical talks to be informative and useful.

We haven’t done a full review of this app, but the original iteration of this app, ReachMD CME, made it into our old top medical apps list.

Cost: Free

6) MedCalc

We’ve always been fans of MedCalc, now the most popular free medical calculator in the App Store. There’s not much to say about it, other than it’s created by physicians who are dedicated to keeping it as a free resource for medical professionals. Also, don’t forget Epocrates Rx (free) has a great medical calculator built.

Cost: Free

7) NeuroMind

NeuroMind is one of the two medical apps on this list that we haven’t reviewed on iMedicalApps. Its a great tool for medical students, neurology residents, and even neurosurgeons. It contains a wide range of information, from basic neuro-anatomy to the WHO Safe Surgery checklist items.

Cost: Free

8. Drug trials

Drug Trials is an app we featured on one of our “recently released free medical apps” list. If you find yourself using clinicaltrials.gov, then this is a great app to have. It’s packed with features such as eligibility criteria, e-mail out functionality, and it can even use Google Maps to show the location of the trial!

We reviewed another similar app awhile back, Clinical Trials, but Drug Trials is just as good or slightly better. And unlike Clinical Trials ($7.99), this one is free.

Cost: Free

9) Eponyms (for students)

Webster’s definition of Eponym is: one for whom or which something is or is believed to be named. In medicine, we encounter this all the time when memorizing obscure diseases or pathologies. This app contains over 1700 of these medical eponyms with short descriptions of each – a nice learning tool for students.

Note, this is the “student” version of the app. If you’re no longer a student the developers ask you to download the $1.99 version of the app – and it contains the same content.

Cost: Free

10) MSK Radiology Teaching File – LITE

This was another app we featured on one of our regular columns, “recently released free medical apps”. MSK Radiology is the lite version of Radiopaedia.org’s Radiology Teaching Files: Volume 3, an app designed to teach radiology. Although this is a lite version, I was surprised to find out how much information it packs in 10 full cases.

This lite version comes included with some relatively common pathologies and even though it’s free, you could definitely get some good learning accomplished if you’re a resident or a medical student. There are other LITE versions of Radiopaedia.org’s content with similar formats. Usually I wouldn’t include a LITE version of an application in this list of free medical apps, but this app had plenty of content. Also, if you find the cases useful the full cost is $4.99 for each set of 50 cases, not a bad price.

Cost: Free

Conclusion:

So there you have it, the top 10 free medical apps for the iPhone and iPod Touch that are actually useful to medical professionals. We’ve reviewed 8 out of 10 of these apps, and I encourage you to look at our full catalog of reviews, where we’ve reviewed a diverse group of apps with various price ranges.
