Implementation of vaccination program of hepatitis B virus (HBV) is universal in infants in the mid-1980s has resulted in a significant decline in the incidence hepatocellular carcinoma (HCC) among children and adolescents in Taiwan. That's according to a report published in the Journal of the National Cancer Institute online edition of 16 September 2009.

Hepatitis B is a major cause of hepatocellular carcinoma - a type of primary liver cancer - especially in endemic areas of chronic HBV infection, as occurred in many parts of Asia.

Mei-Hwei Chang and colleagues from Taiwan hepatomas Study Group to investigate whether prevention of HCC after the launch of the program is a universal HBV vaccine to newborns in Taiwan in July 1984 has passed through childhood, and to determine predictors of HCC in the cohort of vaccinated infants when the new born.

Mei-Hwei Chang and colleagues from Taiwan hepatomas Study Group to investigate whether prevention of HCC after the launch of the program is a universal HBV vaccine to newborns in Taiwan in July 1984 has passed through childhood, and to determine predictors of HCC in the cohort of vaccinated infants when the new born.

The researchers used two national HCC list to collect data from 1958 patients aged six to 29 years old when they were diagnosed with liver cancer between 1983 and 2004. Researchers analyzed HCC incidence according to age and gender of the newborn cohort of vaccinated and unvaccinated using Poisson regression models.

In addition, medical records of 64 patients who developed HCC while 5,524,435 had been vaccinated and those without HCC who were born after the universal program began, compared to the characteristics of hepatitis B immunization in infants and status of hepatitis B surface antigen (HBsAg) and hepatitis B antigen "e" (HBeAg) in the mother before birth.

HIV infection and alcohol drinking habits may cause short-term memory until doubled. That's according to new research findings.


The study, published in the internet version of the first edition of Alcoholism: Clinical and Experimental Research, found that more than half of HIV patients in the clinic is also a heavy alcohol drinker and they seemed more troubled by the short-term memory, while long-term memory was not affected.


"The results show that people are able to withhold information for a while, which gives the impression that still can remember the information, while scores of immediate memory is lower, suggesting that these difficulties associated with the ability to learn, or recognize, the information," the study authors Edith V. Sullivan, professor of psychiatric faculty and behavioral sciences at Stanford University School of Medicine said in a press release issued by the journal publisher.



Inability to learn can affect many aspects of a person's life, including routines to abide by the treatment that helps fight HIV, Sara Jo Nixon, professor of psychiatric faculty at the University of Florida said in a press release the same. Strategies to help these patients need to be applied, he added.

Current air pollution is associated with respiratory disease and cardiovascular disease. Recently, the researchers say that the dirty air you breathe can also cause appendicitis. This new study published in the Canadian Medical Association Journal October 5, 2009 found that cases of appendicitis increases when the quality of dirtier air.

Dr. G. Gilaad Kaplan, senior author of the study and assistant professor of medicine division gastroenterologist at the University of Calgary in Alberta says that it makes us think about the causes of appendicitis which may be associated with air pollution. Air pollution is a risk factor that can be modified. If this finding is confirmed and we are able to enact unddang to mengendalian better air pollution, cleaner air, then we can probably prevent more cases of appendicitis. Other experts warn that at this early point in this study, the effect is not so clear.

Dr F. Paul Buckley III, assistant professor of surgery at Texas A & M Health Science Center College of Medicine and a surgeon at Scott & White Healthcare Round Rock, Texas said that this provocative, but there's a big difference between linking a number of factors with the disease and prove that These factors may cause the disease, and this study failed to show cause and effect. Buckey doubt pollution reduction will reduce the incidence of appendicitis. No one really knows why appendicitis or inflammation of the appendix and the infection occurs.

Appendicitis cases rose significantly in the late 19th century and early 20th century, when industrialization in control. Case dropped in the middle and later part of last century, when the law enforced clean air. Meanwhile, according to study authors, the countries that recently experienced an increase in the level of industrialization conditions.

A prevailing theory is that the appendix occurs when the opening to the appendix, an organ such as a bag attached to the large intestine, was blocked. Specifically, some experts believe that fiber intake is lower among citizens of industrialized countries resulted in obstruction of the appendix by feces.

But that does not explain the incidence of appendicitis decreased in the second half of the 20th century, says Kaplan. Air pollution is linked to various health conditions, especially respiratory disease and heart disease, including heart attack and stroke.

Kaplan and his colleagues studied more than 5000 adults treated in hospital in Calgary with appendicitis between 1 April 1999 until the end of 2006. This data is cross referenced with the analysis of air pollutants in the week before hospitalization.



Kaplan said that they found individuals are more likely to come with appendicitis in the week with higher concentrations of air pollution, particularly ozone and nitrogen dioxide.

More cases of appendicitis occur during the warmest months in Canada (April to September, when people are more likely outside the home), and men seemed more affected by air pollution than women. It is not clear why there is this gender difference, the researchers said.

Kaplan theorized that inflammation may explain the link, if proven to exist, between air quality and appendicitis. "This is still speculative, but air pollution may trigger inflammatory appendicitis," he said. "We have a few more steps before we can make that statement. We need to confirm and repeat these findings." Kaplan and co-author of the study planned in various cities in Canada.

Last year, Forbes magazine rated as Calgary the cleanest city of the world and Baku, Azerbaijan, as the dirtiest.

While some activities are tested in relation to their ability to stimulate the growth of strong bones, runs scored results three times higher compared with walking and other exercises. Meanwhile, up the stairs and exercises with an exercise bike, almost no impact on anything.

But that does not mean we should leave the gym to walk and chose to run with reason to worry we will weaken bones, says Charles Milgrom, MD, associate professor of orthopedics from the Hebrew University Medical School in Jerusalem. "Insert ran for 60 seconds in the middle of our walk program, is sufficient to signal the bones to increase bone mass, added Charles.

We do need to "forge" our bones harder, suggested Robert Marcus, MD, director of the aging study unit at Stanford University Medical School. So, if we do not move your body start to step on our feet for walking. As we've become accustomed to running, insert the program also ran 60 seconds. If still seems difficult, begin by running for 10 seconds first, which then continued with the improvement bit by bit. With this strategy, we can feel the bone response better, Dr.Marcus added.




Hate running? We can choose other training alternatives, such as jumping, slapping his hand into the air, tennis, tai chi or aerobics that has a greater impact and provide variety in our regular program. The exercises were also able to make muscles stronger and maintain a better balance, so that we can prevent injury and reduce the risk of bone fractures.

Or want to try suggestions from Dr.Milgrom? Enough to vary our walking program with zig-zag method, or walk forward and suddenly step backwards feet. Because of these sudden changes that can help our bones become stronger. And to make our practice to get perfect results, always accompanied the exercise by consuming foods that have a high calcium content as hormone replacement therapy at menopause.
